Abstract

The present invention provides an aerosol hairspray lacquer containing a film forming resin, plasticizing agent, water and dimethylether.

Claims

1. An aerosol hair spray lacquer comprising in an aerosol container, an aqueous aerosol hair spray composition consisting essentially of:

(a) a homogeneous liquid mixture consisting of water in an amount of 50 to 70% by weight based on the total weight of said composition and dimethylether as propellant in an amount of 20 to 40% by weight based on the total weight of said composition,

(b) a synthetic film-forming resin in an amount of 3 to 20% by weight based on the total weight of said composition, and

(c) a plasticizer in an amount of 10 to 50% by weight based on the weight of the synthetic film-forming resin,

said film forming resin and said plasticizer being soluble in said homogeneous liquid mixture.

2. The lacquer according to claim 1, wherein the synthetic film-forming resin is selected from the group consisting of:

vinyl acetate/vinyl tert-butyl-benzoate/crotonic acid terpolymers,

N-octyl acrylamide/methyl methacrylate/hydroxypropyl methacrylate/acrylic acid/tert-butylamino-ethyl methacrylate copolymer,

vinylpyrrolidone/vinyl acetate copolymer,

vinyl acetate/crotonic acid/vinyl neodecanoate terpolymer,

acrylic acid/ethyl acrylate/N-tert-butylacrylamide terpolymer,

vinyl acetate/crotonic acid copolymer,

vinylcaprolactam/vinylpyrrolidone/dimethylaminoethyl methacrylate polymer and mixtures thereof.

3. The lacquer according to claim 1, wherein the synthetic film-forming resin is vinyl acetate/vinyl tert-butyl-benzoate/crotonic acid (65/25/10) terpolymer neutralized with an alkanolamine.

4. The lacquer according to claim 2, wherein the synthetic film-forming resin is vinyl acetate/vinyl tert-butyl-benzoate/crotonic acid (65/25/10) terpolymer neutralized with an alkanolamine.

5. The lacquer according to claim 1, wherein the plasticizer is selected from the group consisting of:

glycol ethers,

caster oil oxyethylenated with 40 moles of ethylene oxide,

benzyl alcohol,

alkyl citrates and their acetylated derivatives,

1,3-butylene glycol,

propylene carbonate,

lauric acid diethanolamine and mixtures thereof.

6. The lacquer according to claim 2, wherein the plasticizer is selected from the group consisting of:

glycol ethers,

caster oil oxyethylenated with 40 moles of ethylene oxide,

benzyl alcohol,

alkyl citrates and their acetylated derivatives,

1,3-butylene glycol,

propylene carbonate,

lauric acid diethanolamine and mixtures thereof.

7. The lacquer according to claim 1, which further contains a conventional cosmetic ingredient selected from the group consisting of a softener, a perfume, a silicone, a sun filter, a colorant, a preservative, a foam inhibitor, a vitamin and a protein.

8. The lacquer according to claim 2, which further contains a conventional cosmetic ingredient selected from the group consisting of a softener, a perfume, a silicone, a sun filter, a colorant, a preservative, a foam inhibitor, a vitamin and a protein.
