 Foreword 
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountered when goods and services are exchanged 
within the Community will be removed.  
In order to achieve this objective, the Community established an East African Standards Committee mandated 
to develop and issue East African Standards.   
The Committee is composed of representatives of the National Standards Bodies in Partner States, together 
with the representatives from the private sectors and consumer organizations. Draft East African Standards 
are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments 
received are discussed and incorporated before finalization of standards, in accordance with the procedures 
of the Community. 
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .  
EAS 127 was prepared by Technical Committee EAS/TC 074 , Surface active agents . 
This third edition cancels and replaces the second edition (EAS 127:2011), which has been technically 
revised. FOR COMMENTS ONLYEAS 127-1 : 2013

 Introduction 
There are two main groups of detergents, namely, the soaps and synthetic detergents. In order to guide th e 
production of synthetic detergents of well-defined quality and also to safeguard consumer interests, it has 
been felt desirable to formulate this standard. 
Synthetic detergents are of three types: anionic, cationic and non-ionic. Anionic synthetic detergents of the 
alkyl aryl type, such as dodecylbenzene sulfonic acid, are now produced in fairly Iarge quantities and hence 
priority has been given for the standardization of this material. 
It has been discovered that equally good cleaning can be achieved at relatively low detergent levels. With the 
advance of technology, other equally effective, environmentally safe and cheaper builders can be used 
instead of Sodium Tripolyphosphate (STPP) which is currently being used. Phosphates have been known to 
bring eutrofication in water bodies and companies world over are doing away with them and encouraging use 
of alternative builders such as zeolites and carbonates, and therefore for this reason the requirement for levels 
of STPP are being progressively phased out in the standard with a view of eliminating them in the near future.  
The standard is more composition based than performance based and for that reason performance measures 
for cleaning efficiency and detergency tests have been included. This edition emphasizes on the 
biodegradability of the surfactants used to manufacture detergent powders and a method for determining the 
same has been developed.

 Annex B 
(normative) 
 
Determination of non -detergent organic matter  
B.1 General 
The term non-detergent organic matter includes hydrocarbons, fatty alcohols and perfumes. Using petroleum 
ether and under the conditions prescribed, non-detergent organic matter only is extracted leaving any 
alkylolamide present in the material. 
B.2 Apparatus 
B.2.1 Evaporating basin 
B.2.2 Separating funnels, 1 000-mL capacity 
B.2.3 Wide mouthed flat-bottomed flask, 200-mL capacity  
B.2.4 Buchner flask, 500-mL-capacity fitted with a sintered glass filter funnel (porosity 4)  
B.3 Reagents 
B.3.1 Ethyl alcohol, 50 %, 70 %. 90 % and 96% (by volume) 
B.3.2 Petroleum ether,  boiling range 40 °C to 60 °C non-volatile residue at 80 °C maximum 0.001% 
B.3.3 Acetone,  non-volatile residue at 80 °C maximum 0.001 % 
B.4 Procedure  
B.4.1 Weigh accurately about 5 g of the material in a 150-mL squat beaker. Extract with 50 m L of hot 
90 % ethanol by heating on the steam bath for about 2 min stirring and breaking up any hard lumps with a 
glass rod flattened at the end. 
Allow the solid matter to settle and decant the hot aIcoholic solution through a sintered glass filter funnel 
(porosity 4) fitted to a 500-mL Buchner flask to which suction is applied. Repeat the extraction in a similar 
manner with five further consecutive 30-mL quantities of boiling 90 % ethanol. Pass each extract in turn 
through the filter into the flask. 
B.4.2 Transfer quantitatively all the combined filtrate from the Buchner flask to a 1-L separating funnel 
and rinse the flask four times with 40-mL quantities of distilled water, transferring each wash in turn to the 
separating funnel. Add 100 mL of petroleum ether, swirl gently to ensure adequate mixing and allow the two 
phases to separate. Run off the aqueous alcoholic layer into a second separating funnel, and extract with 75 
mL of petroleum ether. Repeat the extraction of the aqueous alcoholic phase in the third separating funnel 
with a further 75 mL of petroleum ether. Combine the three ether extracts in the first separating funnel. Rinse 
each of the two empty funnels with a few millilitres petroleum ether and add the rinsing to the combined ether 
extracts. 
B.4.3 Wash the combined ether extracts and rinsing (see B.4.2) with four successive 50-mL portions of 
70 % ethyl alcohol, shaking and removing the alcoholic phase each time. Transfer the ether layer in stages to 
a tared flask and evaporate off the solvent. Add 10 mL of acetone and evaporate off the solvent. Rotate the 
flask on a steam bath during the operation. Cool the flask to about 60 °C to 65 °C, gently blow out the last 
traces of solvent with a current of dry air, cool in a desiccator and weigh. FOR COMMENTS ONLYEAS 127-1: 2013

 Annex C 
(normative) 
 
Determination of matter insoluble in water  
C.1 Procedure 
C.1.1  Starting with a fresh portion of the material, weigh accurately about 5 g of the material into a beaker, 
and digest with 50 ml of ethyl alcohol by heating on a steam bath for about 2 min. Stir and break up any hard 
lump with a glass rod flattened at one end. Allow the solid matter to settle and decant the hot alcoholic 
solution through a sintered gl ass filter funnel fitted to a Buchner flask, to which suction is applied. Repeat the 
alcoholic digestion in a similar manner with five further consecutive 30 -ml portions of boiling ethyl alcohol. 
Filter each extract in turn through the same sintered glass  funnel and, finally, wash the residue several times 
with hot ethyl alcohol to remove all the alcohol solubles. Dry the sintered glass funnel with the residue in an 
air-oven at a temperature of 105 °C ± 2 °C until a constant mass is obtained.  
 
C.1.2 Even after digestion with five 30-ml portions of boiling ethyl alcohol, the alcohol insoluble portion may 
sometimes be found to be sticky. In that case, treat it further with more boiling ethyl alcohol until it is free from 
active matter and the alcohol insoluble portion is no longer sticky. Do not dry or weigh the matter insoluble in 
alcohol. After filtering and washing the residue thoroughly with hot ethyl alcohol, change the receiver, extract 
the residue with successive portions of distilled water at about 60 °C, and wash the residue several times to 
remove all the water solubles. Dry the sintered glass funnel with the residue in an air-oven at a temperature of 
105 °C ± 2 °C until a constant mass is obtained. 
C.2 Calculation 
The matter insoluble in water is expressed as follows: 
Matter insoluble in water, % by mass = 
mm1100  
where 
m1 is the mass , in grams , of matter insoluble in water; and  
m is mass , in grams,  of material taken for the test.

(normative) 
 
Sampling procedure for powder detergents 
D.1 General requirements 
D.1.1 In drawing preparing, storing and handling samples, the precautions in D.1.2 – D.1.7 shall be 
observed.  
D.1.2 Samples shall not be taken from places exposed to damp air, dust or soot. 
D.1.3 The sampling instruments shall be clean and dry when used. 
D.1.4 The samples, the material being sampled, the sampling instruments and the containers for samples 
shall be protected from adventitious contamination. 
D.1.5 The samples shall be placed in clean and dry glass containers. The sample containers shall be of 
such a size that they are almost completely filled by the sample. 
D.1.6 Each container shall be sealed airtight after filling, and marked with full details of sampling which 
include, date of sampling, batch or code number, name of manufacturer, and other important particulars of the 
consignment. 
D.1.7 The samples shall be stored in such a manner that the temperature of the material does not vary 
unduly from the normal temperature, and that they are protected from light. 
D.2 Scale of sampling 
D.2.1 In a single consignment, all the packages containing non-soapy detergents of the same type and 
form, and drawn from the same batch of manufacture, shall constitute a lot. If the consignment consists of 
packages containing non-soapy detergents of different types and forms, then the packages containing non-
soapy detergents of the same type form and batch of manufacture shall be grouped together, and such group 
shall constitute a separate lot. 
D.2.2 For ascertaining the conformity of the lot to the requirements prescribed in this standard, tests shall be 
carried out on each lot separately. The number (n) of packages to be selected for drawing the samples shall 
depend upon the size (N) of the lot and shall be in accordance with Table D.1.

NOTE  When the size of  the lot is 3 packages or less, the number of containers to be selecte d and the 
criteria for judging the conformity of the lot to the specifications should be as agreed on between the 
purchaser /inspector  and the supplier.  FOR COMMENTS ONLYEAS 127-1: 2013 
© EAC 2013  – All rights reserved  9 
 D.2.3 The packages shall be selected at random and to ensure randomness of selection, a random number 
table shall be used. In case such tables are not available, the procedure given below may be adopted. 
Starting from any package, count all the packages in one order as 1, 2, 3,…, up to r and so on, where r is the 
integral part of N/n, (N being the lot size and n the number of packages to be selected). Every rth package thus 
counted shall be withdrawn to give a sample for the purposes of test. 
D.3 Preparation of gross samples, test sample and reference sample 
D.3.1 Gross sample 
From each one of the packages selected as in D.2, draw at random one or more containers. The material in 
the containers so chosen shall be nearly thrice the quantity required for purpose of test as indicated in D.4. 
The powder from the containers selected shall be disintegrated, if aggregated, and mixed thoroughly to give 
the gross sample for the package. 
D.3.2 Test sample 
D.3.2.1  Segregate carefully the gross samples of powders. From the gross representing each form of 
synthetic detergent take a small but equal quantity of material and mix thoroughly into a composite sample 
which should be of a size sufficient to carry out triplicate testing for all the characteristics specified under D.4. 
The composite samples representing each form and type of synthetic detergent shall be divided into three 
equal parts, one for the purchaser/inspector, another for the supplier, and the third for the referee. 
D.3.2.2  The remaining portion of the material in each of the gross samples shall be divided into three 
equal pans, each forming an individual sample. One set of individual samples, representing the n selected 
packages shall be for the purchaser/inspector, another for the supplier, and the third for refere nce. 
D.3.2.3  A ll the composite and individual samples shall be transferred to separate containers. These 
containers shall then be sealed airtight with stoppers, and labelled with full particulars of identification given in 
D.1.6. 
D.3.3 Refere nce samples 
D.3.3.1 The refere nce samples shall consist of a composite sample and a set of individual samples. All 
the containers shall bear the seals of both the purchaser/inspector and the supplier, and shall be kept at a 
place agreed to between the two parties. 
D.3.3.2  Refere nce samples shall be used in case of any dispute between the purchaser/inspector and the 
supplier. 
D.4 Number of tests 
D.4.1 Tests for the determination of active ingredient shall be performed on each of the individual samples. 
D.4.2 Tests for the determination of other requirements specified in Table 1 shall be conducted on the 
composite sample. FOR COMMENTS ONLYEAS 127-1: 2013 
10 © EAC 2013  – All rights reserved  
 D.5 Criteria for conformity 
D.5.1 For individual samples 
D.5.1.1 For the characteristic, which has been determined on the individual sample, the mean (X) and the 
range (R) of test results shall be calculated as follows: 

resultstestof Numberresultstestof SumMean X
 
Range ( R) is the difference between the maximum and the minimum value of test results. 
D.5.1.2 If the specification limit for the characteristic is given as a minimum, the value of the expression 
(
X- KR) shall be calculated from the relevant test results (see also D.5.1 .5). If the value so obtained is 
greater than or equal to the minimum limit, the lot shall be declared as conforming to the requirement for the 
characteristic. 
D.5.1.3 If the specification limit for the characteristic is given as a maximum, the value of the expression 
(
X+ KR) shall be calculated from the relevant test results (see also D.5.1.5) . If the value so obtained is less 
than or equal to the maximum limit, the lot shall be declared as conforming to the requirement for the 
characteristic. 
D.5.1.4 If the characteristic has two-sided specification limits, then the values of the expression (
X  ± KR) 
shall be calculated from the relevant test results (see also D.5.1.5).  If the value so obtained lies between the 
two specification limits, the lot shall be declared as conforming to the requirement for the characteristic. 
D.5.1.5 The value of the factor K referred to in D.5.1.2 - D.5.1 .4 shall be chosen in accordance with Table
