Structured cosmetic composition, especially lipstick, having good non-transfer properties, comprising lipid phase containing volatile solvent and structuring polymer with pendant and/or terminal lipid chains

摘要

Structured composition (A) comprises at least one liquid lipid phase containing volatile solvent(s) (VS), structured by polymer(s) (I) of weight average molecular weight 100000 or less, comprising (a) polymeric backbone consisting of hydrocarbon repeating agents containing heteroatom(s) and (b) optionally functionalized, pendant and/or terminal 6-120C lipid chain(s) bonded to units (a). Independent claims are included for: (i) a lipstick composition having at least one continuous liquid lipid phase containing VS and structured by non-waxy polymer(s), providing a deformable elastic solid of hardness 30-150 g in the absence of wax; (ii) a cosmetic care, make-up or treatment process for human keratin materials, involving application of (A); and (iii) the use of a combination of VS and (I) (having weight average molecular weight 1000-30000) in a cosmetic composition (or for the production of a composition), to reducing the transfer and/or deposition of a film of the composition applied to keratin materials onto a support contacted with the film, improve the hold of the film and/or reduce migration.
