JOURNAL OF COSMETIC SCIENCE 224 Comments All products were yellow in color. • The product made with silicone complex was crystal clear, while the one made with the • silicone quat had a slight haze. The product with the silicone complex did not affect the viscosity. • Foam heights: • (a) The product with the silicone complex was similar in both foam and viscosity to the control. (b) The product with silicone quat had lower foam and viscosity indicating interaction between the cation and anion. EVALUATIONS These two products were then evaluated for wet and dry combing on 10 inch virgin brown hair. Three two gram swatches were used with one gram of shampoo for each swatch. The water temperature used for wetting and rinsing the hair was a constant 25°C. All the swatches were rinsed until squeaky clean or for at least one minute. After the wet hair evaluation (Table XIV), the swatches were left to air dry and then the dry comb evaluation (Table XV) was performed. The scale used for all evaluations is from 1 to 5, 5 being the best. Figure 3. Silicone quaterniun 20.

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.
