Abstract
A cosmetic ingredient including at least one plant squalane and at least one mixture of C24 to C48 alkanes, in at least dimeric form, chosen amongst the alkanes of formula (I), where n is 1 or 0, R1, R′1, R2, R′2, R3 and R′3, which may be identical or different, are chosen amongst hydrogen atoms, methyl radicals, and linear C8 to C30 alkyl radicals, at least one of R1, R′1, R2, R′2, R3 and R′3 is chosen amongst the linear C8 to C30 alkyl radicals, and at least one and at most one of R1, R′1, R2, R′2, R3 and R′3 is a methyl radical. The mixture of C24 to C48 alkanes have a viscosity between 12 and 25 mm2/s at 40° C.
