 Introduction  
 
Research and investigation  found  that Zeolite  is the most suitable and ideal  replacement  for Sodium tripolyphosphate 
(STPP)  as the main builder in most of the detergents  due to  eutrophication  effect  to the water sources  which is 
caused  by STTP affec ting the life of living organisms  especially aqu atic organism s hence aquatic -ecosystem 
disturbed . 
 
Zeolite  is synthesized normally in  two different ways:  
a) from amorphous hydrogels prepared from high purity sources of sodium silicates and sodium aluminates,  and 
b) from kaolin by calcinations followed by reaction with aqueous sodium hydroxide.  
The formula of zeolite, normally used by detergent industry is Na 12(AlO2.SiO2)12.27H 2O. Zeolite is  manufactured as 
zeolite slurry first and then spray dried to form zeolite powder. In the spray dried  detergent manufacturing process, 
zeolite is used in the slurry form and spray drying in the zeolite plant is hence  eliminated. Zeolite whenever dispatched 
in the slurry form is stabilized and sent under the nomenclature ‘Zeolite  master batch .  
 
Zeolite in powder form is used in detergent cakes and in detergent powders prepared by dry  mixing process  is 
generally used as a builder in detergent industry. S ince it causes  eutrophication , there was intensive research for an 
alternative  to STPP. After rigorous

stirrer. A 50μ sieve is attached to the Mocker apparatus . The Mocker apparatus is made ready as per  instructions 
given by the supplier. Then the suspension  is poured into the Mocker apparatus by means of a  funnel and sieved at 
a -water pressure of (0.3 -0.5) kg/cm2 (150 L /h). The suspension is added in portions, so  that the filtering surface 
keeps as fre e as possible. When  the major quantity of the sample has passed through  the sieve, the noise of the 
water jet changes.  It becomes louder and hissing noise is heard. Continue  to sieve for 3 min more. Then the 
apparatus is switched  off, the test sieve is rem oved and dried in the oven at11 0°C for 30 min. The sieve is cooled 
and weighed to  constant mass. Then the residue is carefully removed  and the empty sieve is weighed again.

ºC. To dissolve the soluble salts, add 10 ml of dilute hydrochloric acid and 20 ml of water to the residue and digest 
for 5 minutes on the water -bath. Filter the residue, which is mainly silica, through a Whatman fil ter paper and wash 
the residue on the filter paper with hot water till it is free from chlorides. Keep the residue on the filter paper and 
collect the filtrate and washings in original dish.  
 
G.5.2.1  Evaporate to dryness the filtrate and washings on the wa ter-bath; moisten the residue with 10 mL dilute 
hydrochloric acid and again evaporate to dryness. Heat at 110 ºC ± 5 ºC for one hour, add to the residue 10 ml of 
dilute hydrochloric acid and 20 ml of water and digest as before to dissolve the soluble salts . Filter any additional 
silica separated on a separate filter paper and wash it free from chlorides as before.  
 
G.5.2.2  Transfer both the filter papers and the residues as obtained under A.5.2 and A.5.2.1 to a platinum crucible 
previously ignited and weigh ed without cover. Ignite it in a muffle furnace, slowly raising its temperature until free 
from carbon. Cover the crucible with a platinum cover, heat to the highest temperature of blast burner for 15 minutes. 
Cool in a desiccator and weigh without the cru cible cover.  
 
G.5.2.3  Add sufficient water just to moisten the contents of the crucible and add 2 to 3 drops of concentrated sulfuric 
acid. Slowly add 10 ml of hydrofluoric acid. Evaporate to a small volume on the water -bath; add another portion of 
about 1 0 ml of hydrofluoric acid and evaporate to fumes of sulfuric acid. Heat the crucible gently at first over an open 
flame to drive off sulfuric acid and finally at a red heat. Cool in a desiccator and weigh. Repeat the heating, if 
necessary, till constant we ight is obtained.

 Annex H 
(normative)  
 
Sampling of Zeolite powder  
 
H.1 General Requirements  
H.1.1 In drawing, preparing, storing and handling  samples, the following precautions shall be observed.  
H.1.1.1  Samples shall be taken in a protected place, not  exposed to damp air, dust or soot.  
H.1.1.2  The sampling instruments shall be clean and  dry when used.  
H.1.1.3 The samples, the material being sampled, the  sampling instruments and the containers for samples  shall be 
protected from adventitious contamination.  
H.1.1.4 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.  
H.1.1.5 Each container shall be sealed airtight after  filling and marked with full details of sampling, date  of sampling, 
batch or code number, name of  manufacturer, and other important particulars of the  consignment.  
H.1.1.6  The samples shall be stored in such a manner  that the temperature of the material does not vary unduly  from 
the normal state and that they are protected from  light.  
H.2 Scale of Sampling  
Lot 
H.2.1  In a single consignment, all the packages containing  mater ial of the same type, and drawn from the same  
batch of manufacture, shall constitute a lot.  
H.2.2 For ascertaining the conformity of the lot to the  requirements prescribed in this st andard, tests shall be  carried 
out on each lot separately. The number (n) of bags to be selected for drawing the sample shall depend  upon the size 
(N) of the lot, and shall be in accordance  with Table 2.  
Table 2 Scale of Sampling  
SL. N Lot size  Sample size  
1.  Up to 50 3 
2.  51 to 100 4

 H.2.3 The bags  shall be select ed at random. In  order  to ensure the randomness of selection, a random number  table 
shall be used . In the absence of a random number table, the following procedure may be adopted:  Starting from any 
package in the lot , count them  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 bags to be selected). Every  rth package thus counted shall be withdrawn to  give the 
required sample size’.  
H.3 Preparation of gross samples,  
Test samples and reference samples  
H.3.1 Gross Samples  
H.3.1.1 From each one of the bags selected as in H.2, draw at random one or more containers. The material  in the 
containers so chosen  shall be nearly thrice the  quantity required for purposes of test as indicated  in H.4. 
H.3.1.2 The material from the containers -selected as  in H.3.1.1 shall be disintegrated, if necessary, and  mixed 
thoroughly to give the gross sample for the bag.  
H.3.2 Test Samples  
H.3.2.1  Segregat e carefully the gross samples. From  each gross sample, take a small but equal quantity of  material 
and mix it thoroughly into a composite sampl e which should be of a size sufficient to carry out triplicate  test for all 
the characteristics specified under H.4. The  composite sample shall be divided into three equal parts,  one for the 
purchaser, and another  for the supplier, and the  third for the referee.  
H.3.2.2  The remaining portion of the material in each  one of the gross samples shall be divided into three  equal 
parts, each forming an individual sample. One  set of individual samples representing the n selected  bags for the 
purchaser, another for the supplier, and  the third for the referee.  
H.3.2.3  All the composite and individual samples shall  be transferred to separate containers. These containers  shall 
then be sealed airtight with stoppers, and labeled with full particulars of identification given in H.1.1.5.  
H.3.3 Reference samples  
H.3.3.1  The reference samples shall consist of a  composite sampl e and a set of n individual samples.  All the 
containers sha ll bear the seals of both the  purchaser and the supplier, and shall be kept at a place  agreed to between 
the two parties.  
H.3.3.2  Reference samples shall be  used in cases  of any dispute between the  purchaser and the supplier.  
H.4 Number of Tests  
H.4.1 Tests for the determination of active ingredient  shall be performed on each of the individual samples.  
H.4.2 Tests for the determination of the remaining  characteristics given in Table 1 shall be conducted on  the 
composite sample.

 For the characteristic which has been determined on  the individual sample, the mean ( x̅) and the range (R)of test 
results shall be calculated as follows:  
Mean ( x̅) =Sum  of test  results
Number  of test  results 
Range ( R) = Difference between the maximum and  minimum values of test results.  
NOTES  
1. The value of the expression ( x̅— kR) shall be calculated  from the relevant test results [see also Note 2]. 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  that 
characteristic.  
2. The value of the factor k referred to in Note 1 shall be  chosen in accordance with Table 3, depending upon the  acceptable 
quality level, that is, the percentage of nonconforming  bags that may be tolerated reasonably.  
Table 3 Value of ‘k’ for Achieving Different  
SL. N  Acceptable Quality Level  Value of ‘k’  
1.  Not more than 3.0 percent defective  0.4 
2.  Not more than 1.5 percent defective  0.5 
3.  Not more than 0.5 percent defective  - 
 
H.5.2 For Composite Sample  
For declaring the conformity of the lot to the  requirements of all the remaining characteristics  determined on the 
composite sample, the test results  for each on e of the characteristics  satisfies  the relevant  requirement given in 
Table 1.  TBS/CDC -2(5413) P 3
