326 Exchange Drive Arlington, Texas 76011 817-469-7777 Technical Data Sheet SPI-305M INCI Name: Polyacrylamide & C13-14 Isoparffin & Laureth-7 Properties SPI-305M is a pre-neutralized polymer in ready to use liquid form (water in oil emulsion). It is a rheology modifier working as a thickener, and as an emulsifier (stabilizer). The product can be used to make gels, cream-gels and emulsions easily under very moderate shear at cold temperature. While also being able to emulsify various kinds of oil and also acts as a very good pigment dispersant because of its lipodispersible character.

Technical Data Sheet SPI-305M Regulatory INCI Name: Polyacrylamide & C13-14 Isoparffin & Laureth-7 Chemical Description of the polyacrylamide: acrylamide/sodium acryloyldimethyltaurate copolymer CAS No: 38193-60-1 / 64742-47-8 / 3055-97-8 China: Listed in IECIC Japan: Fit for quality specifications of QD Resistance to Electrolytes For testing resistance on electrolytes, NaCl was added to the 2% solution (in water), and check change in viscosity. Test results show decreasing trend of viscosity is similar.
Resistance to Chelating Agents For testing resistance on electrolytes, EDTA-2Na was added to the 2%Multicare solution (in water), and check change in viscosity. Test results show decreasing trend of viscosity is similar. Viscosity/ dose curve in de-ionized water (DI Water) Method Test Result Concentration 0.5-5.0% Using automatic agitation in low concentration In high concentration, using manual agitation The product viscosity profile in DI water versus concentration is very similar to the benchmark one
Viscosity Stability According to ph The test results show the trend of viscosity variation is very similar. The products maintains high viscosity from ph 3 to 11. The formula used contains 3% SPI-305M and 97% water. Add Lactic Acid or 20% NaOH solution drop by drop to 3% SPI-305M solution.

The viscosity was checked at normal temperature after 10 minutes of agitation. The results of the test using SPI-305M shows that the product is as compatible as benchmark with usual preservatives Tested Formulation Thickener (SPI-305M): 3% Preservatives: 0.6% Phenoxy Ethanol: 1.0% Perfume: 1.0 % Water QS: 100%
