Abstract

The instant disclosure relates to hair styling compositions and products comprising the hair styling compositions. The hair styling compositions include: one or more soft latex film-forming polymers having a glass transition temperature (Tg) of less than 35° C. or less; one or more hard latex film-forming polymers having a glass transition temperature (Tg) of 35° C. or more; less than 15 wt. % of water; and at least 80 wt. % of one or more organic solvents, wherein the composition has a shear viscosity of up to about 70 cP at 23° C. The compositions may further comprise one or more propellants, and are useful in products such as aerosol hair sprays, pump hair sprays, hair mousses, hair foams, hair gels, etc. The disclosure further relates to methods for styling the hair using the compositions and products.

First claim

The invention claimed is:

1. A hair styling composition comprising:
about 1 to about 6 wt. % of acrylates copolymer;
about 0.5 to about 4 wt. % of polyacrylate-2 crosspolymer;
about 5 to about 15 wt. % of water;
at least 80 wt. % to about 95 wt. % of an alcohol selected from ethanol, isopropyl alcohol, butanol, and a mixture thereof; and
about 0.1 to about 3 wt. % of tributyl citrate;
wherein the weight percentages are based on the total weight of the hair styling composition, and the hair styling composition has a shear viscosity of up to about 70 cP at 23° C.

2. A non-aerosol hair styling product comprising a spray bottle, the spray bottle containing a mechanical spray pump device and a hair styling composition of claim 1 .

3. An aerosol hair styling product comprising a canister, the canister containing a propellant and a hair styling composition of claim 1 .

4. An aerosol hair styling product of claim 3 , wherein the propellant is selected from dimethyl ether, propane, n-butane, isobutene, and a mixture thereof.

5. An aerosol hairspray product comprising a canister, the canister containing:
a vapor phase comprising a propellant; and
a juice phase comprising a hair styling composition comprising:
about 1 to about 6 wt. % of acrylates copolymer;
about 0.5 to about 4 wt. % of polyacrylate-2 crosspolymer;
5 to about 15 wt. % of water;
at least 80 wt. % to about 95 wt. % of an alcohol selected from ethanol, isopropyl alcohol, butanol, and a mixture thereof; and
about 0.1 to about 3 wt. % of tributyl citrate;
wherein the weight percentages are based on the total weight of the juice phase.

6. A method for styling hair comprising applying to hair the hair styling composition of claim 1 .
