(15) The primary biodegradability requirements

should be

instrumental analyses in those cases in which semi-specific
analytical methods are not suitable.

(16) The determination of biodegradability test-methods and
the record-keeping of lists of derogations are technical
matters and should be revised taking into account
technical and scientific developments as well as regulatory
developments.

equipment, instruments, apparatus, etc.);

transport

and

of

— ‘Other cleaning and washing preparations’, intended for

any other washing and cleaning processes.

2.

‘Washing’ means the cleaning of laundry, fabrics, dishes
and other hard surfaces.

3.

‘Cleaning’ has the meaning defined by EN ISO 862.

4.

‘Substance’ means chemical elements and their compounds
in the natural state or obtained by any production process,
including any additive necessary to preserve the stability of
the products and any impurity deriving from the process
used, but excluding any solvent which may be separated
without affecting the stability of the substance or changing
its composition.

6.

7.

8.

‘Surfactant’ means any organic substance and/or prep-
aration used in detergents, which has
surface-active
properties and which consists of one or more hydrophilic
and one or more hydrophobic groups of such a nature and
size that it is capable of reducing the surface tension of
water, and of forming spreading or adsorption monolayers
at the water-air interface, and of forming emulsions and/or
microemulsions and/or micelles, and of adsorption at
water-solid interfaces.

a

the structural change
‘Primary biodegradation’ means
(transformation) of
surfactant by micro-organisms
resulting in the loss of its surface-active properties due
to the degradation of the parent substance and conse-
quential
loss of the surface-active property as measured
by test methods listed in Annex II.

‘Ultimate aerobic biodegradation’ means the level of biode-
gradation achieved when the surfactant is totally used by
micro-organisms in the presence of oxygen resulting in its
breakdown to carbon dioxide, water and mineral salts of
any other elements present (mineralisation), as measured
by test methods listed in Annex III, and new microbial
cellular constituents (biomass).

6.
The Commission shall publish the list of surfactants that
have obtained derogation, with the corresponding conditions
or limitations of use, as provided in Annex V.

Article 6

Refusal of derogation

1. Where the Commission considers refusing to grant a
derogation,
it shall do so in accordance with the procedure
referred to in Article 12(2), and on the basis of the following
criteria:

— use in high volumes;

— use

in wide-dispersive

applications,

rather

than in

low-dispersive applications;

— socio-economic benefits do not outweigh the impact on

human health and the environment.

As long as the Commission has not decided on a request
2.
for derogation,
the placing on the market and use of the
surfactant in question may be maintained, provided the manu-
facturer can show that the surfactant was already in use on the
Community market at the date of entry into force of this
Regulation and that

the request
within two years from that date.

3.
If the Commission refuses to grant a derogation, it shall
do so within 12 months of receiving from a Member State the
evaluation mentioned in Article 5(3), except in the case of
Article 5(4) and (6) of Decision 1999/468/EC where the
period shall be 18 months. It may set a transitional period
during which the placing on the market and use of
the
surfactant in question shall be phased-out. This transitional
period shall not exceed two years from the date of
the
Commission Decision.

4.
The Commission shall publish in Annex VI the list of
surfactants that have been identified as not complying with
this Regulation.

Article 7

Testing of surfactants

All tests referred to in Articles 3 and 4 and in Annexes II, III,
IV and VIII shall be conducted in compliance with the
standards mentioned in Annex I.1 and in accordance with
testing requirements under Article 10(5) of Regulation (EEC)
No 793/93. For this purpose, it is sufficient to apply either the
EN ISO/IEC standard or the principles of good laboratory
for those tests for which the principles of
practice, except
good laboratory practice have been made mandatory.
In
cases where surfactants are used in detergents which were
placed on the market before the entry into force of
the
above standard, existing tests that were performed using the
best scientific knowledge available, and that were performed to
a standard comparable to those of the standards mentioned in
Annex I may be accepted on a case-by-case basis. The manu-
facturer or the Member State may submit to the Commission
any case over which there is doubt or dispute. A decision shall
then be taken in accordance with the procedure laid down in
Article 12(2).

Article 8

Duties of the Member States

1. Member States shall appoint the competent authority or
authorities
responsible for communicating and exchanging
information relating to the management of this Regulation
and inform the Commission of the full name and address of
these authorities.

2.
Each Member State shall notify to the other Member
States and the Commission the list of approved laboratories,
with full name and address, that are competent and authorised
to carry out the tests required by this Regulation. Member
States shall demonstrate the competence of the above labora-
tories according to the standard EN ISO/IEC 17025 mentioned
in Annex I.1. This requirement shall be deemed to be fulfilled if

ANNEX II

Primary biodegradability test methods for surfactants in detergents

Primary biodegradability is measured by the determination in biodegraded liquors of the remaining level of parent
surfactants. This Annex begins with a list of the test-methods common to all classes of surfactants, and then lists under
headings A to D the analytical test procedures specific to each class of surfactant.

The pass criterion for primary biodegradability shall be a level of at least 80 %, as measured according to the test
methods below.

The reference method for the laboratory testing of surfactants in this Regulation is based on the Confirmatory test procedure
in the OECD method, described in Annex VIII.1. Changes to the Confirmatory test procedure are permissible provided that
they comply with EN ISO 11733.

1. The OECD method published in the OECD's technical report of 11 June 1976 on the ‘Proposed Method for the

Determination of the Biodegradability of Surfactants in Synthetic Detergents’.

TEST METHODS

2. The method in use in France, approved by the ‘arrêté du 24 décembre 1987’ published in the Journal officiel de la
République française of 30 December 1987, p. 15385, and by the standard NF 73-260 of June 1981, published by
the Association française de normalisation (AFNOR).

3. The method in use in Germany, established by the ‘Verordnung über die Abbaubarkeit anionischer und nichtion-
ischer grenzflächenaktiver Stoffe in Wasch- und Reinigungsmitteln’ of 30 January 1977, published in the Bundes-
gesetzblatt of 1977, Part I, p. 244, as set out in the Regulation amending that Regulation of 4 June 1986, published
in the Bundesgesetzblatt of 1986, Part I, p. 851.

4. The method in use in the United Kingdom called the ‘Porous Pot Test’ and described in Technical Report No 70

(1978) of the Water Research Centre.

5. The ‘Confirmatory test procedure’ in the OECD method, described in Annex VIII.1 (including possible changes in
operating conditions as proposed in EN ISO 11733). This is also the reference method used for the settlement of
litigation.

A. ANALYTICAL METHODS FOR ANIONIC SURFACTANTS

The determination of anionic surfactants in the tests shall be done by the Methylene Blue Active Substance (MBAS)
analysis according to the criteria established in Annex VIII.2. For those anionic surfactants not reacting to the above-
mentioned MBAS method, or if it seems more appropriate for reasons of efficiency or precision, appropriate specific
instrumental analyses such as high performance liquid chromatography (HPLC) or gas chromatography (GC) are to be
applied. Samples of the pure surfactant of interest shall be provided by the manufacturer to the competent authorities of
the Member States upon request.

B. ANALYTICAL METHODS FOR NON-IONIC SURFACTANTS

The determination of non-ionic surfactants in the tests shall be done by the Bismuth Active Substance (BiAS) method,
according to the analytical procedure established in Annex VIII.3. For those non-ionic surfactants not reacting to the
abovementioned BiAS method, or if it seems more appropriate for reasons of efficiency or precision, appropriate
specific instrumental analyses such as HPLC or GC are to be applied. Samples of the pure surfactant of interest shall
be provided by the manufacturer to the competent authorities of the Member States upon request.

C. ANALYTICAL METHODS FOR CATIONIC SURFACTANTS

The determination of cationic surfactants in the tests shall be done by the Disulfine Blue Active Substance (DBAS)
analysis according to the following DBAS procedures: The method in use in the Federal Republic of Germany, (1989)
DIN 38 409 — Ausgabe: 1989-07. For those cationic surfactants not reacting to the abovementioned test method, or if
it seems more appropriate for reasons of efficiency or precision (this must be justified) appropriate specific instrumental
analyses such as HPLC or GC are to be applied. Samples of the pure surfactant of interest shall be provided by the
manufacturer to the competent national authorities of the Member States upon request.

Ultimate biodegradability (mineralisation) test methods for surfactants in detergents

ANNEX III

A. The reference method for laboratory testing of surfactant ultimate biodegradability in this regulation is based on the

EN ISO standard 14593:1999 (CO2 headspace test).

Surfactants in detergents shall be considered as biodegradable if the level of biodegradability (mineralisation)
measured according to one of the five following tests (1) is at least 60 % within twenty-eight days:

1. EN ISO Standard 14593:1999. Water quality. — Evaluation of ultimate aerobic biodegradability of organic
compounds in aqueous medium. — Method by analysis of inorganic carbon in sealed vessels (CO2 headspace
test). Pre-adaptation is not to be used. The ten days window principle is not applied. (Reference method).

2. Method of the Directive 67/548/EEC Annex V.C.4-C (Carbon dioxide (CO2) Evolution Modified Sturm Test):

Pre-adaptation is not to be used. The ten days window principle is not applied.

3. Method of the Directive 67/548/EEC Annex V.C.4-E (Closed Bottle): Pre-adaptation is not to be used. The ten days

window principle is not applied.

4. Method of the Directive 67/548/EEC Annex V.C.4-D (Manometric Respirometry): Pre-adaptation is not to be used.

The ten days window principle is not applied.

5. Method of the Directive 67/548/EEC Annex V.C.4-F (MITI: Ministry of International Trade and Industry-Japan):

Pre-adaptation is not to be used. The ten days window principle is not applied.

B. Depending on the physical characteristics of the surfactant, one of the methods listed below might be used if
appropriately justified (2). It should be noted that the pass criterion of at least 70 % of these methods is to be
considered as equivalent to the pass criterion of at least 60 % referred to in methods listed in point A. The adequacy
of the choice of the methods listed below shall be decided on a case by case confirmation, in accordance with Article
5 of this Regulation.

1. Method of the Directive 67/548/EEC Annex V.C.4-A (Dissolved Organic Carbon DOC Die-Away): Pre-adaptation
is not to be used. The ten days window principle is not applied. The pass criteria for biodegradability measured
according to the test shall be at least 70 % within twenty-eight days.

2. Method of the Directive 67/548/EEC Annex V.C.4-B (Modified OECD Screening-DOC Die-Away): Pre-adaptation
is not to be used. The ten days window principle is not applied. The pass criteria for biodegradability measured
according to the test shall be at least 70 % within twenty-eight days.

NB: All the abovementioned methods, taken from Council Directive 67/548/EEC, can also be found in the publication
‘Classification, Packaging and Labelling of Dangerous Substances in the European Union’, Part 2: ‘Testing Methods’.
European Commission 1997. ISBN 92-828-0076-8.

(1) These five tests are identified as the most suitable for surfactants.
(2) The DOC methods could give results on the removal and not on the ultimate biodegradation. The Manometric Respirometry and the

MITI would not be appropriate in some cases because the high initial test concentration could be inhibitory.

ANNEX IV

Complementary risk assessment for surfactants in detergents

For those surfactants for which an environmental risk assessment is available in the context of Directive 93/67/EEC, or
Regulation (EEC) No 793/93 and Regulation (EC) No 1488/94, and Technical Guidance Documents, this risk assessment
shall be considered together with the complementary risk assessment run in the scope of this Regulation.

The complementary risk assessment run in the scope of this Regulation, in case it is likely that recalcitrant metabolites
are produced, shall be considered in the context of assessments made on the basis of Directive 93/67/EEC or Regulation
(EEC) No 793/93. This is to be assessed case by case and in particular on the basis of the results of the tests referred to
in part 3.

The study shall cover the aquatic environmental compartment. Additional
information relating to specific risk
assessment concerns might be required by the Committee referred to in Article 12(2) on a case by case basis. Additional
information might include other environmental compartments such as sewage sludge and soil. A tiered approach shall
be adopted concerning the information required for the technical file referred to in Articles 5 and 9. The file shall
contain at least the information described under points 1, 2 and 3 below.

However, to minimise testing, and especially to avoid unnecessary animal testing, the additional studies listed under
point 4.2.2 should be requested only where such information is necessary and proportionate. In case of dispute
concerning the extent of additional information required, a Decision may be taken in accordance with the procedure
laid down in Article 12(2).

As noted in Article 13, the guidelines included in this Annex for the Decisions on derogation may be adapted as
appropriate on the basis of the accumulated experience.

The information on use patterns given in this section shall be sufficient to allow an approximate but realistic
estimate of function and environmental exposure to the surfactant as associated with its use in detergents. It shall
include the following:

— importance of the application (societal value),

— use conditions (release scenario),

— use volume,

— availability and suitability of alternatives (performance and economic considerations),

— assessment of relevant environmental information.

3.

Information on the potential recalcitrant metabolites

Toxicity information on test liquors shall be provided. If no data are available on residue identity, the information
referred to in point 4.2.1 may be requested, depending on the potential risk, the importance and the quantity of the
surfactant used in detergents. In conflicting cases concerning this information, a Decision may be taken in accordance
with the procedure laid down in Article 12(2).

Any of the tests described in Annex III, may be run with pre-adapted inoculum in order to provide evidence of
the relevance of pre-adaptation for the surfactant.

4.1.2. Inherent Biodegradability Tests

At least one of the tests referred to below shall be included:

— method of the Directive 67/548/EEC, Annex V.C.12 (Modified SCAS test),

— method of the Directive 67/548/EEC, Annex V.C.9 (Zahn-Wellens).

Failure to pass the inherent biodegradability test would indicate potential
for persistency which may be
considered, in general terms, as sufficient to prohibit the placing on the market of such a surfactant except in
cases where the criteria set out in Article 6 indicate that there is no justification for refusing a derogation.

4.1.3. Activated Sludge Simulation Biodegradability Tests

The following tests referred below shall be included:

— method of the Directive 67/548/EEC, Annex V.C.10 (including possible changes in operating conditions as

proposed in EN ISO 11733).

Failure to pass the activated sludge simulation biodegradability test would indicate potential for the release of the
metabolites by sewage treatment, which may be considered, in general terms, as evidence of need for a more
complete risk assessment.

4.2.

Toxicity testing of biodegradation test liquors

Toxicity information on test liquors is to be provided on:

4.2.1. Chemical and physical information, such as:

— identity of the metabolite (and analytical means by which it was obtained);

— key physical chemical properties (water solubility, Octanol: Water partition coefficient (Log Po/w, etc.).

will consider as well the potential of metabolites for bio-concentration and their partitioning to the sediment
phase.

Moreover, if some metabolites are suspected for endocrine disrupting activity, it is recommended to determine if
these have potential to result in adverse affects as soon as validated testing schemes to assess such adverse effects
are available.

ANNEX VIII

TEST METHODS AND ANALYTICAL METHODS

The following test and analytical methods apply to control procedures for detergents on the market carried out by
Member States:

1.

1.1.

Reference method (confirmatory test)

D e f i n i t i o n

This method describes a laboratory model of the activated sludge + secondary settler which is designed to
simulate municipal sewage treatment. The conditions described are those from the Directives that preceded
this Regulation. Improved state-of-the-art operating conditions can be applied to this test method as described
in EN ISO 11733.

1.2.

E q u i p m e n t n e e d e d f o r m e a s u r e m e n t

The method of measurement employs the small-activated sludge plant shown in Figure 1, and in greater detail
in Figure 2. The equipment consists of a sewage vessel A for synthetic sewage, dosing pump B, aeration vessel
C, settling vessel D, air-lift pump E to recycle the activated sludge, and vessel F for collecting the treated
effluent.

Vessels A and F must be of glass or suitable plastic and hold at least twenty-four litres. Pump B must provide a
constant flow of synthetic sewage to the aeration vessel; this vessel, during normal operation, contains three
litres of mixed liquor. A sintered aeration cube G is suspended in the vessel C at the apex of the cone. The
quantity of air blown through the aerator shall be monitored by means of a flow meter H.

1.3.

S y n t h e t i c s e w a g e

A synthetic sewage is employed for the test. Dissolve in each litre of tap water:

— 160 mg peptone;

— 110 mg meat extract;

— 30 mg urea, CO(NH2)2;

— 7 mg sodium chloride, NaCl;

— 4 mg calcium chloride, CaCl2.2H2O;

— 2 mg magnesium sulphate, MgSO4.7H2O;

— 28 mg of di-potassium hydrogen phosphate, K2HPO4;

— and 10 ± 1 mg of the surfactant.

The synthetic sewage is freshly prepared daily.

1.4.

P r e p a r a t i o n o f s a m p l e s

Uncompounded surfactants are examined in the original state. Active content of surfactant samples must be
determined in order to prepare the synthetic sewage (1.3).

1.5.

O p e r a t i o n o f e q u i p m e n t

Initially, fill aeration vessel C and settling vessel D with synthetic sewage. The height of the vessel D should be
so fixed that the volume contained in the aeration vessel C is three litres.

Inoculation is made by introducing 3 ml of a secondary effluent of good quality, freshly collected from a
treatment plant dealing with a predominantly domestic sewage. The effluent must be kept under aerobic
conditions in the period between sampling and application. Then set the aerator G, air-lift E and dosing device
B in operation. The synthetic sewage must pass through the aeration vessel C at a rate of one litre per hour;
this gives a mean retention time of three hours.

C 305 E/30

EN

Official Journal of the European Union

16.12.2003

The rate of aeration should be so regulated that the contents of vessel C are kept constantly in suspension and
the dissolved oxygen content is at least 2 mg/l. Foaming must be prevented by appropriate means. Anti-
foaming agents that inhibit the activated sludge or contain surfactants must not be used. The air-lift pump E
must be set so that the activated sludge from the settling vessel is continually and regularly recycled to
aeration vessel C. Sludge which has accumulated around the top of the aeration vessel C, in the base of the
settling vessel D, or in the circulation circuit must be returned to the circulation at least once each day by
brushing or some other appropriate means. When the sludge fails to settle, its settleability may be increased
by the addition of 2 ml portions of a 5 % solution of ferric chloride, repeated as necessary.

The effluent from the settling vessel D is accumulated in vessel F for twenty-four hours, following which a
sample is taken after thorough mixing. Vessel F must then be carefully cleaned.

1.6.

C h e c k i n g m e a s u r i n g e q u i p m e n t

The surfactant content (in mg/l) of the synthetic sewage is determined immediately before use.

The surfactant content (in mg/l) of the effluent collected over twenty-four hours in vessel F should be
determined analytically by the same method, immediately after collection: otherwise the samples must be
preserved, preferably by freezing. The concentrations must be determined to the nearest 0,1 mg/l surfactant.

As a check on the efficiency of the process, the chemical oxygen demand (COD) or the dissolved organic
carbon (DOC) of the glass fibre filtered effluent accumulated in vessel F and of the filtered synthetic sewage in
vessel A is measured at least twice per week.

The reduction in COD or DOC should level off when a roughly regular daily surfactant degradation is
obtained at the end of the running-in period shown in Figure 3.

The content of dry matter in the activated sludge contained in the aeration vessel should be determined twice
a week in g/l. If it is more than 2,5 g/l, the excess activated sludge must be discarded.

The degradation test is performed at room temperature; this should be steady and kept between 19-24 °C.

1.7.

C a l c u l a t i o n o f b i o d e g r a d a b i l i t y

The percentage degradation of surfactant must be calculated every day on the basis of the surfactant content
in mg/l of the synthetic sewage and of the corresponding effluent accumulated in vessel F.

The degradability values thus obtained should be presented graphically as in Figure 3.

The degradability of the surfactant should be calculated as the arithmetic mean of the values obtained over the
twenty-one days that follow the running-in and acclimatisation period, during which degradation has been
regular and the operation of the plant trouble-free. In any event the duration of the running-in period should
not exceed six weeks.

The daily degradation values are calculated to the nearest 0,1 % but the final result is given to the nearest
whole number.

In some cases it may be permissible to reduce the frequency of sampling but at least fourteen results collected
over the twenty-one days which follow the running-in period should be used in calculating the average.

2.1.

Determination of anionic surfactants in biodegradability tests

P r i n c i p l e

The method is based on the fact that the cationic dye methylene blue forms blue salts with anionic surfactants
(MBAS), which can be extracted with chloroform. To eliminate interference, the extraction is first effected
from alkaline solution and the extract is then shaken with acidic methylene blue solution. The absorbency of
the separated organic phase is measured photometrically at the wavelength of maximum absorption of
650 nm.

P r o c e d u r e

The samples for analysis must not be taken through a layer of foam.

After thorough cleaning with water, the equipment used for the analysis must be thoroughly rinsed with
methanolic hydrochloric acid (2.2.10) and then with deionised water before using.

Filter the activated sludge plant influent and effluent to be examined immediately on sampling. Discard the
first 100 ml of the filtrates.

Place a measured volume of the sample, neutralised if necessary, into a 250 ml separating funnel (2.2.11). The
volume of sample should contain between 20 and 150 µg of MBAS. At the lower MBAS content, up to
100 ml of sample may be used. When using less than 100 ml, dilute to 100 ml with deionised water. Add to
the sample 10 ml of buffer solution (2.2.1), 5 ml of neutral methylene blue solution (2.2.2) and 15 ml of
chloroform (2.2.4). Shake the mixture uniformly and not too vigorously for one minute. After phase sepa-
ration, run the chloroform layer into a second separating funnel, containing 110 ml of deionised water and
5 ml of acidic methylene blue solution (2.2.3). Shake the mixture for one minute. Pass the chloroform layer
through a cotton-wool filter previously cleaned and wetted with chloroform into a graduated flask (2.2.12).

C a l i b r a t i o n c u r v e

Prepare a calibration solution from the standard substance dodecylbenzene sulphonic acid methyl ester (tetra-
propylene type mol. wt. 340) after saponification into the potassium salt. The MBAS is calculated as sodium
dodecyl benzene sulphonate (mol. wt. 348).

From a weighing pipette, weigh 400 to 450 mg of dodecyl-benzene-sulphonic-acid-methyl-ester (2.2.5) to the
nearest 0,1 mg in a round-bottomed flask and add 50 ml of ethanolic potassium hydroxide solution (2.2.6)
and some boiling granules. After mounting the reflux condenser, boil for one hour. After cooling, wash the
condenser and ground glass joint with about 30 ml of ethanol, and add these washings to the contents of the
flask. Titrate the solution with sulphuric acid against phenolphthalein until it becomes colourless. Transfer this
solution to a 1 000 ml graduated flask (2.2.14), dilute to the mark with deionised water and mix.

Part of this surfactant stock solution is then further diluted. Withdraw 25 ml, transfer to a 500 ml graduated
flask (2.2.13), dilute to the mark with deionised water and mix.

This standard solution contains:

3.1.

Determination of non-ionic surfactants in biodegradation test liquors

P r i n c i p l e

Surface active agents are concentrated and isolated by gas stripping. In the sample used, the quantity of
non-ionic surfactant should be in the range 250-800 µg.

The stripped surfactant is dissolved in ethyl acetate.

After phase separation and evaporation of the solvent, the non-ionic surfactant is precipitated in aqueous
solution with modified Dragendorff reagent (KBiI4 + BaCl2 + glacial acetic acid).

The precipitate is filtered, washed with glacial acetic acid and dissolved in ammonium tartrate solution. The
bismuth in the solution is titrated potentiometrically with pyrrolidinedithiocarbamate solution at pH 4-5 using
a bright platinum indicator electrode and a calomel or silver/silver chloride reference electrode. The method is
applicable to non-ionic surfactants containing 6-30 alkylene oxide groups.

M e t h o d

3.3.1.

Concentration and separation of the surfactant

Filter the aqueous sample through a qualitative filter paper. Discard the first 100 ml of the filtrate.

Into the stripping apparatus, previously rinsed with ethyl acetate, place a measured quantity of the sample,
such that it contains between 250-800 µg non-ionic surfactant.

To improve the separation add 100 g sodium chloride and 5 g sodium bicarbonate.

If the volume of the sample exceeds 500 ml, add these salts to the stripping apparatus in solid form, and
dissolve by passing nitrogen or air through.

If a smaller-sized sample is used, dissolve the salts in 400 ml water and then add to the stripping apparatus.

Add water to bring the level to the upper stopcock.

Cautiously add 100 ml ethyl acetate on top of the water.

Fill the wash-bottle in the gas-line (nitrogen or air) two-thirds full with ethyl acetate.

Pass a gas stream of 30-60 l/h through the apparatus; the use of a flowmeter is recommended. The rate of
aeration must be increased gradually at the beginning. The gas rate must be so adjusted that the phases
remain noticeably separate to minimise the mixing of the phases and the solution of the ethyl acetate in the
water. Stop the gas flow after five minutes.

If there is a reduction of more than 20 % in the volume of the organic phase through solution in water, the
sublation must be repeated paying special attention to the rate of gas flow.

Run off the organic phase into a separating funnel. Return any water in the separating funnel from the
aqueous phase — it should only be a few ml — to the stripping apparatus. Filter the ethyl acetate phase
through a dry qualitative filter paper into a 250 ml beaker.

Put a further 100 ml ethyl acetate into the stripping apparatus and again pass nitrogen or air through for five
minutes. Draw off the organic phase into the separating funnel used for the first separation, reject the aqueous
phase and run the organic phase through the same filter as the first ethyl acetate portion. Rinse both the
separating funnel and the filter with about 20 ml ethyl acetate.

Evaporate the ethyl acetate extract to dryness using a water-bath (fume cupboard). Direct a gentle stream of
air over the surface of the solution to accelerate the evaporation.

3.3.2.

Precipitation and filtration

Dissolve the dry residue from 3.3.1 in 5 ml methanol, add 40 ml water and 0,5 ml dilute HCl (3.2.3) and
stir the mixture with a magnetic stirrer.

To this solution add 30 ml of precipitating agent (3.2.6) from a measuring cylinder. The precipitate forms
after repeated stirring. After stirring for ten minutes leave the mixture to stand for at least five minutes.

Filter the mixture through a Gooch crucible, the base of which is covered with a glass-fibre filter paper. First
wash the filter under suction with about 2 ml glacial acetic acid. Then thoroughly wash the beaker, magnet,
and crucible with glacial acetic acid, of which about 40-50 ml is necessary. It is not necessary to quanti-
tatively transfer the precipitate adhering to the sides of the beaker, to the filter, because the solution of the
precipitate for the titration is returned to the precipitating beaker, and the remaining precipitate will then be
dissolved.

16.12.2003

C 305 E/35

3.3.3.

Dissolution of the precipitate

Dissolve the precipitate in the filter crucible by the addition of hot ammonium tartrate solution (about 80 °C)
(3.2.8) in three portions of 10 ml each. Allow each portion to stand in the crucible for some minutes before
being sucked through the filter into the flask.

Put the contents of the filter flask into the beaker used for the precipitation. Rinse the sides of the beaker with
a further 20 ml of tartrate solution to dissolve the rest of the precipitate.

Carefully wash the crucible, adapter and filter flask with 150-200 ml water, and return the rinsing water to
the beaker used for the precipitation.

3.3.4.

The titration

Stir the solution using a magnetic stirrer (3.2.16), add a few drops of bromocresol purple (3.2.5) and add the
dilute ammonia solution (3.2.9) until the colour turns violet (the solution is initially weakly acid from the
residue of acetic acid used for rinsing).

Then add 10 ml standard acetate buffer (3.2.10), immerse the electrodes in the solution, and titrate poten-
tiometrically with standard ‘carbate solution’ (3.2.11), the burette tip being immersed in the solution.

The titration rate should not exceed 2 ml/min.

The endpoint is the intersection of the tangents to the two branches of the potential curve.

It will be observed occasionally that the inflection in the potential curve becomes flattened; this can be
eliminated by carefully cleaning the platinum electrode (by polishing with emery paper).

3.3.5.

Blank determinations

At the same time run a blank determination through the whole procedure with 5 ml methanol and 40 ml
water, according to the instructions in 3.3.2. The blank titration should be below 1 ml, otherwise the purity
of the reagents (3.2.3, 3.2.7, 3.2.8, 3.2.9, 3.2.10) is suspect, especially their content of heavy metals, and they
must be replaced. The blank must be taken into account in the calculation of the results.

3.3.6.

Control of the factor of the ‘carbate solution’

Determine the factor for the carbate solution on the day of use. To do this, titrate 10 ml of the copper
sulphate solution (3.2.12) with ‘carbate solution’ after the addition of 100 ml water and 10 ml standard
acetate buffer (3.2.10). If the amount used is a ml, the factor f is:

and all the results of the titration are multiplied by this factor.

Every non-ionic surfactant has its own factor, depending on its composition, particularly on the length of the
alkene oxide chain. The concentration of non-ionic surfactant is expressed in relation to a standard substance
— a nonyl phenol with ten ethylene oxide units (NP 10) — for which the conversion factor is 0,054.

Using this factor the amount of surfactant present in the sample is found expressed as mg of NP 10
equivalent, as follows:

(b-c) × f × 0,054 = mg non-ionic surfactant as NP 10

where:

b = volume of ‘carbate solution’ used by the sample (ml),

c = volume of ‘carbate solution’ used by the blank (ml),

Preliminary treatment of anionic surfactants to be tested

P r e l i m i n a r y n o t e s

Treatment of samples

The treatment of anionic surface-active agents and formulated detergents prior to the determination of
primary biodegradability in the confirmatory test is:

Products

Treatment

Anionic surfactants

None

Formulated detergents

Alcoholic extraction followed by separation of the
anionic surfactants by ion exchange

The purpose of the alcoholic extraction is to eliminate the insoluble and inorganic ingredients of the
commercial product, which in some circumstances might upset the biodegradability test.

4.1.2.

Ion-exchange procedure

Isolation and separation of anionic surface active agents from soap, non-ionic and cationic surfactants are
required for correct biodegradability tests.

This is achieved by an ion-exchange technique using a macro-porous exchange resin and suitable eluants for
fractional elution. Thus soap, anionic and non-ionic surfactants may be isolated in one procedure.

4.1.3.

Analytical control

After homogenising,
is determined
according to the MBAS analytical procedure. The soap content is determined by a suitable analytical method.

the concentration of anionic surfactants in the synthetic detergent

This analysis of the products is necessary to calculate the quantities required for preparing fractions for the
biodegradability test.

Quantitative extraction is not necessary; however, at least 80 % of the anionic surfactants should be extracted.
Usually, 90 % or more is obtained.

4.2.

P r i n c i p l e

From a homogeneous sample (powders, dried pastes and dried liquids) an ethanol extract is obtained which
contains the surfactants, soap and other alcohol-soluble constituents of the synthetic detergent sample.

The ethanol extract is evaporated to dryness, dissolved in an isopropanol/water mixture and the solution
obtained is passed through a strongly acidic cation exchange/macro-porous anion exchange combination
heated to 50 °C. This temperature is necessary to prevent the precipitation of any fatty acids which may
be present in acidic media.

Any non-ionic surfactants remain in the effluent.

Soap fatty acids are separated by extraction with ethanol containing CO2. The anionic surfactants are then
obtained as ammonium salts, by elution with an aqueous isopropanolic solution of ammonium bicarbonate.
These ammonium salts are used for the degradation test.

Cationic surfactants that might upset the biodegradability test and the analytical procedure are eliminated by
the cation exchanger placed above the anion exchanger.

Preparation of extract

The quantity of surfactants necessary for the biodegradation test is about 50 g MBAS.

Normally, the quantity of product to be extracted will not exceed 1 000 g, but it may be necessary to extract
further quantities of sample. For practical reasons, the quantity of product used should in most cases be
limited to 5 000 g in preparing extracts for the biodegradation test.

Experience has shown that there are advantages in using a number of small extractions rather than one large
extraction. The exchanger quantities specified are designed for a working capacity of 600-700 mmoles of
surfactants and soap.

4.4.2.

Isolation of alcohol-soluble constituents

Add 250 g of the synthetic detergent to be analysed to 1 250 ml ethanol, heat the mixture to boiling point
and reflux for one hour with stirring. Pass the hot alcoholic solution through a coarse-pored suction filter
heated to 50 °C and filter rapidly. Wash the flask and suction filter with approximately 200 ml hot ethanol.
Collect the filtrate and filter washings in a filter flask.

In the case of pastes or liquid products to be analysed, make sure that not more than 55 g anionic surfactants
and 35 g soap are contained in the sample. Evaporate this weighed sample to dryness. Dissolve the residue in
2 000 ml ethanol and proceed as described above.

In the case of powders of low apparent density (< 300 g/l) it is recommended to increase the ethanol ratio in
the relation 20:1. Evaporate the ethanolic filtrate to dryness, preferably by means of a rotary evaporator.

Preparation of ion-exchange columns

CATION-EXCHANGE COLUMN

Place 600 ml cation-exchange resin (4.3.6) in a 3 000 ml beaker and cover by adding 2 000 ml hydrochloric
acid (4.3.8). Allow to stand for at least two hours, with occasional stirring.

Decant the acid and transfer the resin into the column (4.3.12) by means of deionised water. The column
should contain a glass-wool plug.

Wash the column with deionised water at a rate of 10-30 ml/min until the eluate is free of chloride.

Displace the water with 2 000 ml isopropanol/water mixture (4.3.3) at a rate of 10-30 ml/min. The exchange
column is now ready for operation.

ANION-EXCHANGE COLUMN

Place 600 ml anion-exchange resin (4.3.7) in a 3 000 ml beaker and cover by adding 2 000 ml deionised
water.

Allow the resin to swell for at least two hours.

Transfer the resin into the column by means of deionised water. The column should contain a glass-wool
plug.

Wash the column with 0,3 M ammonium bicarbonate solution (4.3.5) until free of chloride. This requires
about 5 000 ml solution. Wash again with 2 000 ml deionised water. Displace the water with 2 000 ml
isopropanol/water mixture (4.3.3) at a rate of 10-30 ml/min. The exchange column is now in the OH-form
and ready for operation.

4.4.4.

Ion-exchange procedure

Connect the exchange columns so that the cation-exchange column is placed on top of the anion-exchange
column.

Heat the exchange columns to 50 °C using thermostatic control.

Heat 5 000 ml of the solution obtained in item 4.4.2 to 60 °C and pass the solution through the exchanger
combination at a rate of 20 ml/min. Wash the columns with 1 000 ml hot isopropanol/water mixture
(4.3.3).

To obtain the anionic surface active agents (MBAS), disconnect
the KAT column. Using 5 000 ml
ethanol/CO2 solution at 50 °C (4.3.4), elute the soap fatty acids out of the KAT column. Reject the eluate.

Then elute the MBAS out of the AAT column with 5 000 ml ammonium bicarbonate solution (4.3.5).
Evaporate the eluate to dryness using a steam bath or in a rotary evaporator.

The residue contains the MBAS (as ammonium salt) and possible non-surfactant anionics that have no
detrimental effect on the biodegradation test. Add deionised water to the residue until a definite volume is
obtained and determine the MBAS content in an aliquot. The solution is used as a standard solution of the
anionic synthetic detergents for the biodegradation test. The solution should be kept at a temperature below
5 °C.

4.4.5.

Regeneration of ion exchange resins

The cation exchanger is rejected after use.

Passing an additional quantity of ammonium bicarbonate solution (4.3.5) down the column at a flow rate of
approximately 10 ml/min until the eluate is free from anionic surfactants (methylene blue test) regenerates the
anion-exchange resin.

P r e l i m i n a r y n o t e s

5.1.1.

Treatment of samples

The treatment of non-ionic surface-active agents and formulated detergents prior to the determination of
primary biodegradability in the confirmatory test is:

Products

Treatment

Non-ionic surfactants

None

Formulated detergents

Alcoholic extraction followed by separation of the
non-ionic surfactants by ion exchange

The purpose of the alcoholic extraction is to eliminate the insoluble and inorganic ingredients of the
commercial product, which in some circumstances might upset the biodegradability test.

5.1.2.

Ion-exchange procedure

Isolation and separation of non-ionic surface active agents from soap, anionic and cationic surfactants are
required for correct biodegradability tests.

This is achieved by an ion exchange technique using a macro-porous exchange resin and suitable eluants for
fractional elution. Thus soap, anionic and non-ionic surfactants may be isolated in one procedure.

5.1.3.

Analytical control

After homogenising, the concentration of anionic and non-ionic surfactants in the detergent is determined
according to the MBAS and BiAS analytical procedure. The soap content is determined by a suitable analytical
method.

This analysis of the product is necessary to calculate the quantities required for preparing fractions for the
biodegradability tests.

Quantitative extraction is not necessary; however, at least 80 % of the non-ionic surfactants should be
extracted. Usually, 90 % or more is obtained.

5.2.

P r i n c i p l e

From a homogeneous sample (powders, dried paste and dried liquids) an ethanol extract is obtained which
contains the surfactants, soap and other alcohol-soluble constituents of the detergent sample.

The ethanol extract is evaporated to dryness, dissolved in an isopropanol/water mixture and the solution
obtained is passed through a strongly acidic cation exchange/macro-porous anion exchange combination
heated to 50 °C. This temperature is necessary to prevent the precipitation of any fatty acids which may
be present in acidic media. The non-ionic surfactants are obtained from the effluent by evaporation.

Cationic surfactants, which might upset the degradation test and the analytical procedure, are eliminated by
the cation exchanger placed above the anion exchanger.

Preparation of extract

The quantity of surfactant necessary for the degradation test is about 25 g BiAS.

In preparing extracts for the degradation tests, the quantity of product to be used should be limited to a
maximum of 2 000 g. Therefore it may be necessary to carry out the operation two or more times in order
to obtain sufficient quantity for the degradation tests.

Experience has shown that there are advantages in using a number of small extractions rather than one large
extraction.

5.4.2.

Isolation of alcohol-soluble constituents

Add 250 g of the synthetic detergent to be analysed to 1 250 ml ethanol and heat the mixture to boiling
point and reflux for one hour with stirring. Pass the hot alcoholic solution through a coarse-pored suction
filter heated to 50 °C and filter rapidly. Wash the flask and suction filter with approximately 200 ml hot
ethanol. Collect the filtrate and filter washings in a filter flask.

In the case of pastes or liquid products to be analysed, make sure that not more than 25 g anionic surfactants
and 35 g soap are contained in the sample. Evaporate this weighed sample to dryness. Dissolve the residue in
500 ml ethanol and proceed as described above.

In the case of powders of low apparent density (< 300 g/l) it is recommended to increase the ethanol ratio in
the relation 20:1.

Evaporate the ethanolic filtrate to complete dryness, preferably by means of rotary evaporator. Repeat the
operation if a greater quantity of extract is required. Dissolve the residue in 5 000 ml isopropanol/water
mixture.

STATEMENT OF THE COUNCIL'S REASONS

I. INTRODUCTION

On 4 September 2002 the C o m m i s s i o n presented its proposal (12319/02 ENT 129 ENV 507
CODEC 1146).

On 26 February 2003 the E c o n o m i c a n d S o c i a l C o m m i t t e e delivered its Opinion (Opinion
CESE 282/2003 (1)).

On 10 April 2003 the E u r o p e a n P a r l i a m e n t concluded its first reading, adopting a number of
amendments (doc. 8310/03 CODEC 448 ENT 59 ENV 213).

On 19 May 2003 the C o u n c i l
( C o m p e t i t i v e n e s s ) reached a political agreement by qualified
majority on the Presidency text set out in doc. 9096/03 ENT 78 ENV 263 CODEC 610, which after
legal/linguistic revision, is now the text of the Common Position, set out in doc. 10595/03.

On 4 November 2003 the Council agreed, pursuant to Article 251 par. 2 of the Treaty, the Common
position and the Statement of the Council's reasons.

II. OBJECTIVE

The objective of this Regulation is to ensure the free movement of detergents in the Internal Market
while at the same time providing a high level of protection for human health and for the environment.
In particular it modernises the existing detergent directives by including provisions on the biodegrad-
ability of surfactants. The proposed new biodegradability tests ensure a higher level of environmental
protection and are applicable to all types of surfactants in detergents. Furthermore, it makes binding the
requirements for the products covered by this Regulation specified in Commission Recommendation
89/542/EEC on labelling of detergents and cleaning products and on specific information to consumers
on the presence of fragrance substances in detergents.

III. ANALYSIS OF THE COMMON POSITION AS SET OUT IN DOC. 10595/03

1. General

The Common Position modifies the Commission Proposal by attempting to cater for the following
requirements:

— better definition of the parties intervening in the authorisation or derogation process;

— clarification of the scope (inter alia by defining the boundaries with respect to biocidal products);

— need to inform and to protect consumers;

— providing clearer guidelines for approved laboratories and for testing methods.

Amendments 2, 4, 8, 17, and 53 of the E.P. were accepted with their original wording, as these
amendments contribute to clarify the text and improve some definitions.

Amendments 3, 18, 27, 34, 35, 36, 37, 45, 46, 52, 55 and 57 were accepted in part, or in
substance, as they either further clarify the text or some parts thereof, or else because they add
provisions which may ease implementation of the Regulation.

All other amendments were rejected (see also item IV hereafter).
