silicones

Gelest offers performance and formulating benefits with truly unique silicones using its expertise as a developer and manufacturer of silicon chemistries for high technology applications.

Diethicone
Diethicones combine excellent slip, increased lubricity with a much broader organic compatibility than Dimethicones, allowing formulation with many common cosmetic materials, including esters, hydrocarbons, waxes, sunscreens, and surfactants. Unlike traditional Dimethicones, Gelest Diethicones wet pigments well, a useful property for the formulation of color cosmetics and sunscreens containing pigments.

Ethylene-Dimethicone Block Polymers
Block Polymers of ethylene and polydimethylsiloxane are solid low melt-point materials. They offer the smoothness of paraffins without the waxy feel. When added to many organic and hydrocarbon systems they reduce tack and increase slip. At higher levels they can form barriers to moisture transmission. Diblock copolymers are more effective in compatibilizing hydrocarbon and silicone materials. Triblock copolymers provide greater emolliency.

Ethylene-Dimethicone Copolymer
Ethylene Siloxane Copolymers are light vehicles that are primarily used as additives to compatibilize or stabilize mixed silicone organic formulations. Incorporation at low levels, typically 1-3%, helps stabilize silicone-organic mixtures that have a tendency to phase separate during storage

Methicones (Trisiloxanes)
Alkyl Trisiloxanes are light, dry emollient oils with good organic compatibility, even greater than that of traditional phenyl trimethicone. They are used to enhance slip and reduce tack in hair care, skin care, and color cosmetics. Organic and inorganic pigments can be easily wetted and dispersed in the Alkyl Trisiloxanes for use in foundations, eye shadows, blushes, and lip color.

Methicones (Polymers)
Alkyl and Alkyl-Aryl Methicones are polysiloxanes with pendant groups that provide good emolliency and skin feel for application in skin treatment and color cosmetics. Alkyl pendants, C8, C14 and C18, in the AM series provide for good common cosmetic ingredient compatibility as well as modify the melt point The Aryl pendant of PM 212 adds gloss and tack.

Specialty Hybrid Siloxanes
Natural product character is imparted to a short emollient silicone tail by combining natural products with one end of a low molecular weight siloxane. The salient characteristics of the natural product are readily retained in formulations, allowing the desirable accent of a natural product, such as shine or cleansing, in a form that is silicone compatible
