Article
Dodecane is a hydrocarbon ingredient, meaning it’s composed of the elements carbon and hydrogen. It belongs to the alkane class, a group of saturated, chemically inert emollients that help prevent water loss from skin and lend a supple texture to skin’s surface.
Of particular note is that dodecane has very light, nearly weightless feel despite its emollient nature. It may be derived from plants or made synthetically (Paula’s Choice uses the former). It’s supplied as a clear, free-flowing liquid.
Dodecane has a wide usage range in cosmetics, from 1–75% depending on desired aesthetics and attributes. For example, much higher levels are used in hair care serums as a replacement for one or more silicones. It is considered non-irritating and safe as used in cosmetics.
