Assignee:

GAF Chemicals Corporation - Wayne NJ

International Classification:

A61K 711

US Classification:

424 71

Abstract:

Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a copolymer of maleic anhydride and an alkyl vinyl ether, and the ethyl and butyl half-esters thereof, in an amount of between 6 and 20% solids. In suitable embodiments of the invention, the resin is the C. sub. 2 -C. sub. 4 alkyl half-ester of maleic anhydride and C. sub. 1 -C. sub. 5 alkyl vinyl ether having a relative viscosity of about 1. 20 to 1. 35 (1% in ethanol).

Stephen C. Johnson - Singapore, SG

Assignee:

ISP Investments Inc. - Wilmington DE

International Classification:

C08F 2610

US Classification:

526264

Abstract:

A hair spray fixative resin comprises a vinyl acetate/alkyl maleate half ester/N-substituted acrylamide terpolymer in a molar ratio of about 1. 0 to 0. 6-0. 8 to 0. 08-0. 12, which is preferably produced by a suspension or solution polymerization process. Utilizing N-substituted acrylamides in place of isoborneol methacrylates in the terpolymer provides superior holding power over conventional hair fixative resins, at lower cost.

International Classification:

A61K 700

US Classification:

424 47

Abstract:

Non-aerosol pump hair spray compositions herein are applied as a fine spray mist, without nozzle clogging, and dried rapidly, to provide superior hair holding power. The compositions includes a hair fixative resin which is a terpolymer of a vinyl ester, an alkyl maleate half ester, and an acrylate ester of a saturated, hydroxylated bicyclic hydrocarbon, in an amount between 6 and 20% solids, and at a relative viscosity of from 1. 10 to below 1. 30.

US Classification:

424 45

Abstract:

An improved hydrocarbon tolerant, aerosol hair spray resin composition includes a fixative polymer which is a tetrapolymer consisting essentially of (1) vinyl acetate, (2) vinyl neodecanoate or vinyl neononanoate, (3) monoisobutyl maleate and (4) N-t-butyl acrylamide, N-t-octyl acrylamide, or isobornyl (meth)acrylate, in a molar ratio from 10:10:15:1 to 26:1:15:1, preferably in a molar ratio of 12. 5:7. 5:15:1, exhibits advantageous small spray particle size, short tack and drying times, and hydrolytic stability, which are the desired performance characteristics on hair.

Assignee:

ISP Investments Inc. - Wilmington DE

International Classification:

A61K 711

US Classification:

424 47

Abstract:

An 80% VOC, single phase aerosol hair spray composition based on greater than 15% hydrocarbons as propellant is described. The composition includes a predetermined small amount of dimethyl ether as cosolvent to assure solubilization of the hair fixative resin, alcohol, water and hydrocarbon components of the composition within a single phase.
