Abstract
Disclosed are non-aqueous compositions capable of forming a gel structure, containing: (a) a low molecular mass N-acyl glutamic acid diamide having a straight-chain alkyl group; (b) a low molecular mass N-acyl glutamic acid diamide having a branched-chain alkyl group; (c) at least one gel-promoting solvent; (d) at least one film former; (e) at least one volatile solvent capable of solubilizing the film former; and (f) at least one colorant; and (g) a polyorganosiloxane-containing polymer, wherein the composition has a hardness value ranging from about 30 to about 300 gf, a melting point of about 500 C or higher, does not require use of wax as a structuring agent. Methods of making and using the compositions are also disclosed.
Claims11
A non-aqueous composition that is capable of forming a gel structure, comprising:
- a structuring agent consisting of:
- (a) a low molecular mass N-acyl glutamic acid diamide having a straight-chain alkyl group comprising dibutyl lauroyl glutamide;
- (b) a low molecular mass N-acyl glutamic acid diamide having a branched-chain alkyl group comprising dibutyl ethylhexanoyl glutamide;
- and (c) at least one polyorganosiloxane polymer comprising a nylon-611/dimethicone copolymer:
- (d) at least one gel-promoting solvent;
- (e) at least one film former;
- (f) at least one volatile solvent capable of solubilizing the film former;
- and
- (g) at least one colorant;
- wherein the composition has a hardness value ranging from about 30 to about 300gf, a melting point of about 50° C. or higher.
A process for making a non-aqueous composition that is capable of forming a gel structure, comprising:
- providing a structuring agent consisting of:
- (a) a low molecular mass N-acyl glutamic acid diamide having a straight-chain alkyl group comprising dibutyl lauroyl glutamide;
- (b) a low molecular mass N-acyl glutamic acid diamide having a branched-chain alkyl group comprising dibutyl ethylhexanoyl glutamide;
- and (c) and at least one polyorganosiloxane polymer comprising a nylon-611/dimethicone copolymer;
- (d) providing at least one gel-promoting solvent;
- (e) providing at least one film former;
- (f) providing at least one volatile solvent capable of solubilizing the film former;
- and
- (g) providing at least one colorant;
- and
- (h) mixing (a)-(g), at a temperature of from about 80° C. to about 125° C., to form a heated composition;
- and (i) cooling the heated composition to form the non-aqueous, structured, gel-form composition, wherein the composition has a hardness value ranging from about 30 to about 300gf, a melting point of about 50° C. or higher.
