Tokyo, May 23, 2001 – Shin-Etsu Chemical Co., Ltd. (Head Office: Tokyo, President: Shunzo Mori) developed and began the sale of a new generation of highly functional hybrid silicone powders,KSP-441and KSP-411, which possess superior flexibility and lubricity. These products were specifically designed to exhibit high absorption of various oils. Adding these new silicone powders to the formulations of a wide variety of cosmetic products results in a uniquely soft and silky feel to the skin, and at the same time, these powders also can be expected to prevent cosmetics from smearing because they have a highly functional sebum absorption quality that minimizes oily skin.
Shin-Etsu’s newly developed unique hybrid silicone powders consist of a spherical silicone rubber core whose surface is coated with silicone resin. They have both the flexibility of silicone rubber and the lubricity of silicone resin, and have superior dispersion quality for cosmetic-product applications. In addition, because it is a hybrid silicone powder with high light-diffusion efficiency, when it is applied on the skin’s surface, it effectively diffuses light and exhibits a soft-focus effect that helps realize natural and beautiful skin. Based on these good characteristics, it is being used in various cosmetic products for the purpose of both improving skin feel and adding high functionality.
These new products that Shin-Etsu Chemical has developed have the superior characteristic of exhibiting very excellent oil-absorption characteristics, when compared to existing cosmetic-powder ingredients. Shin-Etsu’s KSP-411 can absorb a large amount of oil in its inner silicone rubber part, particularly of silicone oils. This product can absorb oil of more than the double its own weight. On the other hand, because it has an alkyl group in its silicone rubber inner core, Shin-Etsu’s KSP-441 is superior in absorbing organic oils. The average particle diameter is 12µm in both products.
By taking advantage of the very excellent oil-absorption characteristics of these innovative new silicone powder products, such beneficial effects are realized as the improved stability of cosmetic products due to the increased viscosity of oils in the cosmetics and the maintaining of a cosmetic’s beautiful finish for a longer period of time as a result of its absorbing of the natural oils in one’s skin that are secreted over time.
This new silicone powder series of products is scheduled to be exhibited at the Shin-Etsu Chemical booth at The 5th Cosmetic Ingredients & Technology Exhibition Japan (CITE Japan 2011). This exhibition is being organized by the Federation of Japanese Cosmetic Ingredients Associations and is being held in Yokohama for three days from May 25 to 27, 2011. This special exhibition is the only one in Japan that is concentrated on cosmetic raw materials and manufacturing technology.
Shin-Etsu Chemical has a line-up of silicone powder products that possess characteristics that provide high functionality and offer a uniquely smooth and silky skin feel in applications for various cosmetic products.
Silicone is a highly functional material that has both organic and inorganic characteristics. Silicones are used as products that can provide high-added value in a wide range of industrial fields such as the electrical, electronics, automotive, construction, cosmetics, and chemical industries.
