Abstract

Abstract A cosmetic oleogel suitable for topical application to the human body surface comprises : (i) from 5 to 95% by weight of a cosmetically acceptable solvent chosen from synthetic hydrocarbon oils derived from poly-a-olefins, the majority of which comprise branched alkyl chains ; and (ii) from 5 to 80% by weight of a cosmetically acceptable hydrophobic polymer thickener for the synthetic hydrocarbon oil, which is preferably substantially free from crosslinking and soluble in the solvent.

Claim 2
Dependent Claim 62 words
A cosmetic oleogel suitable for topical application to the human body surface, which comprises: (i) from 5 to 95% by weight of a cosmetically acceptable solvent chosen from synthetic hydrocarbon oils derived from poly-a-olefins, the majority of which comprise branched alkyl chains; and (ii) from 5 to 80% by weight of a cosmetically acceptable hydrophobic polymer thickener for the synthetic hydrocarbon oil.
Claim 3
Dependent Claim 24 words
An oleogel according to claim 1, wherein greater than 60% of the poly-a-olefins from which the hydrocarbon oil is derived comprise branched alkyl chains.
Claim 4
Dependent Claim 33 words
An oleogel according to claim 1 or claim 2, wherein the hydrocarbon oil has a molecular weight in the range 300 to 2000and/or a viscosity (at 40°C) in the range 5 to 1500cSt.

Claim 7
Dependent Claim 36 words
An oleogel according to claim 4 or claim 5, wherein the polyol from which the polyol fatty acid polyester is derived is a sugar polyol which comprises at least one of a mono-, di- and polysaccharide.
Claim 8
Dependent Claim 45 words
An oleogel according to claim 6, wherein the polyol fatty acid polyester is chosen from: Sucrose octaiosostearate Sucrose octa-2-ethylhexanoate Sucrose fatty acid polyesters derived from palm and palmkernel oil mixtures soyabean oil soyabean and palm oil mixtures palm oil coconut oil, and mixed fish oils.
Claim 9
Dependent Claim 33 words

Claim 10
Dependent Claim 22 words
An oleogel according to any preceding claim, wherein the polymer thickener is substantially free from cross-linking and is soluble in the solvent.
Claim 11
Dependent Claim 15 words
An oleogel according to any preceding claim, wherein the polymer thickener is a polyethylene homopolymer.
Claim 12
Dependent Claim 21 words
