Silicone oils are extremely important in today's cosmetic formulations. They lend an excellent velvety smooth feel to creams and lotions, hair care products, makeup and powders.
Lubrajel is also an extremely important component of the same, lending rheology modification, lubrication and moisture balancing.
Combining these two materials would result in a superior product possessing the desirable properties of each, complementing each other in an elegant manner.
This, however, is not easily accomplished, since Lubrajel® and silicones are not generally compatible.
Although silicone oils may be emulsified into Lubrajel, this takes away from the clarity and colorlessness of the product.
Lubrasil is the unique integration of silicone oil (dimethicone) and Lubrajel [glyceryl polymethacrylate (GPM)] in which the silicone oil is microemulsified using high energy techniques to form this product.
Lubrasil maintains the characteristics of Lubrajel, including the clarity, lubrication, moisture balancing and viscosification.
The characteristics of the dimethicone enhance the Lubrajel by virtually eliminating the "tackiness" associated with formulations employing large concentrations of the material, and it leaves an even softer feel.
Upon application to the skin or hair, the GPM/water/dimethicone complex equilibrium is shifted, thereby releasing moisture and silicone.
The silicone layer floats on the micro-thin layer of GPM, facilitating moisturization by altering the kinetics of the moisture flux.
Lubrasil is used in skin care products at levels between 5 and 40% and may be used in hair care products such as styling gels at similar concentrations.
Lubrasil is compatible to varying degrees with nonionic surfactants, some anionic surfactants, and most water-soluble or dispersible materials that are not highly ionized. |
