2010 TRI/PRINCETON CONFERENCE 225 CONCLUSION The silicone complex is an excellent product for use in a 2 in 1 shampoo and for adding sheen and softness to color treated hair. It left the hair silky soft with no residual feel and the combing was without any tugging or pulling. The comb slipped easily through the swatches, providing signifi cant shine. COACERVATE TECHNOLOGY Silplex J-2S (Figure 4) has been found to be an effective agent for the formation of coacer- vate shampoos. The use of Silplex J-2S allows one to formulate a shampoo (Table XVI, p. 227) with outstanding foam and conditioning using natural oils and castor isostearate succinate, a natural ECOCERT polymer, available from Zenitech. Silplex J-2S is used in baby shampoo at 0.5% to make a family product, is used in body wash, and is very effective for Asian hair. The ability to choose specifi c anionic and cationic materials that interact to build viscosity, provide foam and act to make coacervates offer the formulator unique possibilities.

JOURNAL OF COSMETIC SCIENCE 226 PROCEDURE (1) Into a clean and sanitized stainless steel container equipped with propeller mixer, add water in Phase B (2) Add SLES and betaine, heat up to 70° to 75°C, slowly add cocamide MEA and EGDS, mix slowly while minimizing air incorporation. Mix until uniform, then cool down to room temperature. (3) In another clean and sanitized stainless steel tank equipped with propeller mixer, add water and the rest of ingredients of phase A one by one while minimizing air incorpo- ration. Mix until uniform. (4) Add phase B slowly into Phase A. Mix until uniform (5) Premix Silplex J2-S and Cosmosurf CE-100 until uniform, then add into Phase A+B, mix well. Add the rest of ingredients in Phase C one by one into Phase A+B until homogeneous while minimizing air incorporation. (6) Add ingredients in Phase D one by one. Adjust pH by using citric acid to pH = 5.5 ~ 6.5, and adjust viscosity to 6,000 cps ~ 12,000 cps by adding q.s. NaCl and Crothix. Add fragrance if necessary. PROPERTIES Viscosity (cps) 12,000 pH 5.70 Appearance Opaque white cream FOAM METHOD All products were evaluated with the same procedure. A 1000-ml cylinder with 10-ml increments was used. All samples and distilled water was prepared at 25°C. 1.00 gram Figure 4. Silplex J2S and Silquat J208.
