Abstract:
An anhydrous cosmetic composition comprising:a) a lipophilic material mixture comprising a liquid selected from the group consisting of hydrocarbon oils, fatty acid esters, fatty alcohols and mixtures thereof, and a solid selected from the group consisting of fatty alcohols, fatty acid esters, waxes and mixtures thereof; b) a hydrophilic active material; c) optionally, a colorant; and d) at least one amphiphilic lipid selected from the group consisting of: (1) a linear or branched polyglycerolated derivative having the formula R3Oâ€”[â€”C3H5(OH)Oâ€”]{overscore (n)}â€”Hâ€ƒâ€ƒ(II) â€ƒwherein â€”C3H5(OH)Oâ€” represents the following structures taken in admixture or separately: {overscore (n)} has a statistical average value ranging from 1 to 6, R3 represents: (a) a linear or branched, saturated or unsaturated aliphatic chain containing from 12 to 30 carbon atoms, or a hydrocarbon radical of a lanolin alcohol, (b) R4CO wherein R4 is a linear or branched C11-C29 aliphatic radical, or (c) R5â€”[â€”OC2H3(R6)â€”]â€” wherein R5 has the meaning (a) or (b) of R3; â€”OHC2H3(R6)â€” represents the following structures taken in admixture or separately: â€ƒwherein R6 has the meaning (a) for R3; (2) a linear or branched polyglycerol ether having two fatty chains; (3) a polyoxyethylenated fatty alcohol; (4) a polyoxyethylenated sterol or phytosterol; (5) a polyol ether; (6) a polyol ester oxyethylenated or not; (7) a natural or synthetic glycolipid; (8) a polyglycerolated &agr;-diol; (9) a hydroxyamide having the formula â€ƒwherein R7 represents a C7-C21 alkyl or alkenyl radical, R8 represents a saturated or unsaturated C7-C31 hydrocarbon radical, â€”COA represents a group selected from (i) â€ƒwherein B is an alkyl radical derived from a primary or secondary, mono or polyhydroxylated amine, and R9 represents hydrogen, methyl, ethyl and hydroxyethyl, or (ii) â€”COOZ wherein Z represents the residue of a C3-C7 polyol, (10) an ether or ester having the formula â€ƒwherein A represents â€”OR or â€ƒwherein R represents a saturated or unsaturated hydrocarbon radical and {overscore (n)} has a value of 2 or is a statistical average value n greater than 1 and at most equal to 6, (11) a natural or synthetic phospholipid, and (12) an ionic amphiphilic lipid having the formula â€ƒwherein R1 represents a C7-C21 alkyl or alkenyl radical, R2 represents a saturated or unsaturated C7-C31 hydrocarbon radical and M represents H, Na, K, NH4 or an ammonium ion derived from an amine.
