Testing method of oil adsorption by Di octyl Adepate in silicon filler and talcum powder. And testing methods of Foam Determination of SLES and SLS.
APPARATUS
- Glass Beaker,250ml
- Glass Rod
REAGENTS
- Sample
- Di Octyl Adipate(DOA)
Oil Absorption Procedure
1). Take a clean and dry beaker and weigh the sample based on the following
Name of the Products    Wt of the sample(gms)      Standard Quantity of DOA(gms)
a) Acematt TS-100Â Â Â Â Â Â 2.00Â Â Â Â Â Â 15-18
b) Calcium Carbonate   10.00       9-11
c) Syloid ED-30Â Â Â Â 10.00Â Â Â Â Â Â 9-11
d) Micron Talc Powder  10.00    9-11
2). Now add DOA with well stirring with the help of a glass rod.
3). The sample in the beaker takes the shape of a ball i.e. sample is properly mixed with DOA.
4). Now, note down the consumed quantity of DOA. (If the consumed quantity of DOA is as per
 the described limit that means the supplied sample is OK otherwise it is Not OK.)
DETERMINATION OF FOAM IN DEFOAMER AND FOAM TEST
1. APPARATUS AND REAGENTS
a) 100 ml & 200ml Beaker
b) 500ml measuring Cylinder
c) Stirrer
d) D.M. Water
e) 20 MOLE or 40 MOLE Ethoxylated Non-ionic Emulsifier
2. Foam Testing Procedure
a) Take 100gm D.M. Water and 10gm 20MOLE or 40 MOLE Ethoxylated Non-Ionic Emulsifier.
b) Now Stir it for 10 minutes at 1300RPM.
c) Transfer the whole mass to a 500ml measuring cylinder.
d) Measure the foam height.
e) Add DEFOAMER as per 1 gm/Lit. & shake well.
f) Report the height/ml.
g) Perform the same test for standard and supply.
