Background information on use in cosmetics

Silicones, chemically more precisely poly(organo)siloxanes, is a designation for a group of synthetic polymers in which silicone atoms are connected through oxygen atoms. The volatility and viscosity are determined by the chain length. The silicones include various compounds which contain as a characteristic functional group a polyorganosiloxane. Important classes are: dimethylpolysiloxanes, phenylmethyl polysiloxanes, cyclic methylsiloxanes and siloxanes modified with alkyl groups or PEG (polyethylene glycol). Silicones are water insoluble and have a low surface tension. The low surface tension is the reason for their good spreading quality; they constitute protective films on the skin which are vapor-permeable. They have no comedogenic effect and are particularly well tolerated on skin. Because of their favourable technological and cosmetic properties they are used rather frequently in cosmetics and serve for the improvement of care properties in skin and haircare products. Emulsifiers are often used in cosmetics as excipients. They allow actually unmixable components like oil and water to be brought in a permanently stable emulsion. In this way both aqueous and oily care and active ingredients can be used in one and the same product in cosmetics. Emulsifiers are able to do that since their molecules consist of a lipophilic and a hydrophilic part. In this way they can reduce the interfacial tension which actually exists between two incompatible substances like fat and water. Emulsifiers are, more particularly, used for creams, lotions and cleansing agents. At present emulsifiers are, however, more than only excipients which keep an emulsion stable. Fatty acid esters on the basis of sugar, lecithin or glycerin monodistearate contribute, for instance, to improving the moisture balance of the skin and are, therefore, also considered as cosmetic active ingredients.
