Abstract
The present disclosure relates to hair care and conditioning compositions; and to methods for conditioning, managing, and/or styling the hair using the compositions. The hair conditioning and managing compositions are substantially anhydrous and include: propylene glycol; one or more monoalcohols having from 2 to 6 carbon atoms; one or more cationic surfactants; and one or more fatty compounds. The compositions are solubilized, non-emulsified compositions until applied to wet or damp hair, whereupon the compositions form a lamellar phase in situ.
Claims20
A transparent and substantially anhydrous cosmetic composition comprising:
- about 20 to about 95 wt. % of propylene glycol;
- about 5 to about 70 wt. % of one or more monoalcohols having from 2 to 6 carbon atoms;
- wherein the weight ratio of the propylene glycol to the monoalcohol(s) (propylene glycol:monoalcohol(s)) is from 20:1 to 1:1;
- about 0.1 to about 5 wt. % of one or more cationic surfactants;
- about 0.1 to about 20 wt. % of one or more fatty compounds;
- wherein the composition is a solubilized, non-emulsified composition until applied to the wet or damp hair, whereupon the composition forms a lamellar phase in situ;
- and
- all percentages by weight are based on the total weight of the composition.
A transparent and substantially anhydrous cosmetic composition comprising:
- about 20 to about 95 wt. % of propylene glycol;
- about 5 to about 70 wt. % of ethanol;
- wherein the weight ratio of the propylene glycol to ethanol (propylene glycol:ethanol) is from 20:1 to 1:1;
- about 0.1 to about 5 wt. % one or more cationic surfactants;
- about 0.1 to about 10 wt. % of one or more fatty esters selected from fatty carbonate esters, glycerol fatty esters, sucrose fatty esters, sorbitan fatty ester, fatty acid esters, or mixtures thereof;
- about 0.1 to about 10 wt. % of one or more fatty alcohols selected from cetearyl alcohol, stearyl alcohol, behenyl alcohol, cetyl alcohol, myristyl alcohol, isostearyl alcohol, lauryl alcohol, and a mixture thereof;
- wherein the composition is a solubilized, non-emulsified composition until applied to the wet or damp hair, whereupon the composition forms a lamellar phase in situ;
- and
- all percentages by weight are based on the total weight of the composition.
A method for treating hair comprising applying a transparent and substantially anhydrous cosmetic composition to wet or damp hair and forming a lamellar phase in situ, the transparent and substantially anhydrous cosmetic composition comprising:
- about 20 to about 95 wt. % of propylene glycol;
- about 5 to about 70 wt. % of one or more monoalcohols having from 2 to 6 carbon atoms;
- wherein the weight ratio of the propylene glycol to the monoalcohol(s) (propylene glycol:monoalcohol(s)) is from 20:1 to 1:1;
- about 0.1 to about 5 wt. % of one or more cationic surfactants;
- about 0.1 to about 20 wt. % of one or more fatty compounds;
- wherein the composition is a solubilized, non-emulsified composition until applied to the wet or damp hair, whereupon the composition forms a lamellar phase in situ;
- and
- all percentages by weight are based on the total weight of the composition.
