Polyether modified silicones (SPE) are widely used in personal care industry for many years because of their water affinity as well as their emulsification and dispersing abilities. They are particularly appreciated for their ability to stabilize W/O systems. Such emulsions offer several benefits for cosmetic applications including skin protection and water repellency that make them suitable for applications like moisturizing creams, sun care, color cosmetics or hair care conditioner. The use of SPE allows the formulation of stable W/O systems while imparting pleasant aesthetics to the emulsion. The properties of PEG-10 Dimethicone (Dow Coming® ES-5612 Formulation Aid) were investigated for the production of stable water-in-silicone and water-in-oil formulations with unique textures. Different types of oil phase were investigated including silicone oils, organic oils as well as combinations of both. Other key cosmetics raw materials were also included in the formulations examples such as pigments, sunscreens and anti-perspirant and deodorant actives. The level of the SPE was varied depending on the formulation type in the range 0.5-50%. Studies show that both cold and hot processes are possible producing textures that range from lotion to cream, including liquid to viscous emulsion. [ABSTRACT FROM AUTHOR] |
