BIS-(C1-8 ALKYL LAUROYL LYSINE DECYLCARBOXAMIDE) DIMETHICONE

Substance information

"Alkyl" describes a mixture of alkanols. Alkanols are alcohols which are derived from saturated hydrocarbons. The preceding numbers "C x-y" specify the range of the alkyl (hydrocarbon) chain lengths. The name component "lauroyl" means that the ingredient contains, as fatty acid component, amongst others, lauric acid (dodecanoic acid) (mostly introduced via an acylation reaction). Ingredient on the basis of the amino acid lysine (2,6-diaminohexanoic acid). "Decyl" mostly refers to decanol (decyl alcohol) as alcoholic component or generally a hydrocarbon residue with 10 carbon atoms. Amides are generally conversion products of carbonic acids (carboxylic acids, mostly fatty acids) or other acids with nitrogen compounds (ammonia or alkyl and alkanol amines, amino acids etc). Examples: "stearamides" are amides of the stearic acid, "cocamides" are amides of coconut fatty acids. Ingredient on the basis of poly(di)methyl siloxane ("dimethicone").

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.
