Document Type and Number:
Japanese Patent JP2880126
Kind Code:
B2
Abstract:
A cosmetic compsn. pressurised in an aerosol in the presence of a propellant and capable of forming a foam, comprising, in a cosmetically acceptable aq. medium, at least one associative polyurethane (I) and at least one anionic polymer (II), at least one of (I) and (II) having foam forming capabilities. Pref. (I) contains at least one hydrophilic sequence, at least one hydrophobic sequence and at least one urethane gp., pref. where the hydrophilic sequence is a polyoxyalkylene and esp. a polyoxyethylene sequence and the hydrophobic sequence is a fatty chain contg. 8-30C. Pref. (I) comprises at least two hydrophobic sequences. Specific associative polyurethanes are chosen from polyurethanes of formula (Ia), (Ib) and (Ic): X-Bp-Eq-(B-E)n-Br-Et-X (Ia) in which n = whole number 1-10, p, q, r and t = 0 or 1 provided that at least q or r = 1 and t = 0 when r = 0; when q = 1, then (A) p = r = t = 0, or (b) p = 0 and r = t = 1, or (c) t = 0 and r = p = 1; and when q = 0, then r = 1 and p = t = 0; (H-E-OCH2)sL(Qv-(Du-E-X)w-Rz)m (Ib) in which m = a whole number 2-4, s = a whole number 0-2, m + s = 2-4, w = whole number 1-3, u, v and z = 0 or 1, L -= Y, Z or -O-, Y- hydrophobic hydrocarbon radical contg. at least 1 C atom.
