Abstract

Abstract A perfume composition, with an aqueous phase, having a high concentration of perfume, which contains: a) vesicles which are obtained from at least one non-ionic lipid derived from a linear or branched polyglycerol, associated with a stabilizer present in a proportion of 1 to 10% by weight based on the lipid, the vesicles having an average diameter of between 0.01 mu and 1 mu and the lipids which form the vesicles representing 0.2 to 4% by weight of the total composition; and b) a perfume in the form of droplets having an average diameter of between 0.1 mu and 1 mu and being present in the composition in amounts of between 3 and 20% by weight based on the total composition, the total ratio of the lipid or lipids of the vesicles to the perfume being between 0.05 and 0.2.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 357 words
A perfume composition which is soothing, pleasant to apply, easily spread on the skin and has a pleasant feel comprises in a continuous aqueous phase (a) vesicles obtained from at least one non-ionic lipid consisting of a linear or branched polyglycerol derivative having the formula ##STR5## wherein n has an average statistical value ranging from 2 to 6, and R represents (1) an aliphatic chain R 1 or R 2 CO wherein R 1 is a linear or branched C 12 -C 15 aliphatic radical and R 2 is a linear or branched C 11 -C 17 aliphatic radical, or (2) a radical having the formula ##STR6## wherein R 3 is R 1 or R 2 CO and R 4 is R 1 , R 1 and R 2 being identical or different and having the meanings given above, said non-ionic lipid (a) being combined with cholesterol when R has the meaning defined in (1), above, and (b) being combined with an anionic stabilizer selected from the group consisting of a phosphoric acid ester of a C 12 -C 22 fatty alcohol, a lipoamino acid having an acyl radical R 5 --CO-- wherein R 5 is a C 13 -C 19 hydrocarbon chain, cholesterol sulfate and cholesterol phosphate, said anionic stabilizer being present in an amount ranging from 1 to 10 percent by weight based on the weight of said lipid, said vesicles having an average diameter ranging from 0.01μ to 1μ and said lipid forming said vesicles being present in an amount ranging from 0.2 to 4 percent by weight based on the total weight of said composition, and (b) a perfume comprising one or both of a pleasant smelling natural essential oil or a synthetic product, said perfume being essentially free from a C 1 -C 4 alcohol and being in the form of droplets having an average diameter ranging from 0.1 to 1μ, said perfume being present in an amount ranging from 3 to 20 percent by weight based on the total weight of said composition, and the weight ratio of said lipid forming said vesicles to said perfume ranging from 0.05 to 0.2.
Claim 2
Dependent Claim 357 words
A perfume composition which is soothing, pleasant to apply, easily spread on the skin and has a pleasant feel comprises in a continuous aqueous phase (a) vesicles obtained from at least one non-ionic lipid consisting of a linear or branched polyglycerol derivative having the formula ##STR5## wherein n has an average statistical value ranging from 2 to 6, and R represents (1) an aliphatic chain R 1 or R 2 CO wherein R 1 is a linear or branched C 12 -C 15 aliphatic radical and R 2 is a linear or branched C 11 -C 17 aliphatic radical, or (2) a radical having the formula ##STR6## wherein R 3 is R 1 or R 2 CO and R 4 is R 1 , R 1 and R 2 being identical or different and having the meanings given above, said non-ionic lipid (a) being combined with cholesterol when R has the meaning defined in (1), above, and (b) being combined with an anionic stabilizer selected from the group consisting of a phosphoric acid ester of a C 12 -C 22 fatty alcohol, a lipoamino acid having an acyl radical R 5 --CO-- wherein R 5 is a C 13 -C 19 hydrocarbon chain, cholesterol sulfate and cholesterol phosphate, said anionic stabilizer being present in an amount ranging from 1 to 10 percent by weight based on the weight of said lipid, said vesicles having an average diameter ranging from 0.01μ to 1μ and said lipid forming said vesicles being present in an amount ranging from 0.2 to 4 percent by weight based on the total weight of said composition, and (b) a perfume comprising one or both of a pleasant smelling natural essential oil or a synthetic product, said perfume being essentially free from a C 1 -C 4 alcohol and being in the form of droplets having an average diameter ranging from 0.1 to 1μ, said perfume being present in an amount ranging from 3 to 20 percent by weight based on the total weight of said composition, and the weight ratio of said lipid forming said vesicles to said perfume ranging from 0.05 to 0.2.
Claim 3
Dependent Claim 17 words
The perfume composition of claim 1 wherein said continuous aqueous phase also contains a water-soluble cosmetic adjuvant.
Claim 4
Dependent Claim 16 words
The perfume composition of claim 1 wherein said perfume is admixed with a liposoluble cosmetic adjuvant.
Claim 5
Dependent Claim 30 words
The perfume composition of claim 1 wherein said perfume is present in an amount ranging from 5 to 16 percent by weight based on the total weight of said composition.
Claim 6
Dependent Claim 33 words
The perfume composition of claim 1 wherein said lipid forming said vesicles is present in an amount ranging from 0.5 to 2 percent by weight based on the total weight of said composition.
Claim 7
Dependent Claim 17 words
The perfume composition of claim 1 wherein said phosphoric acid ester is dicetyl phosphate or dimyristyl phosphate.
Claim 8
Dependent Claim 19 words
