Abstract
A low VOC (volatile organic compounds) hair spray composition having a combination of desirable user performance characteristics is described herein. The hair fixative resin in the composition is a terpolymer of 40-75% by weight of a vinyl lactam, preferably vinyl pyrrolidone, 15-40% of a polymerizable carboxylic acid, preferably acrylic acid or methacrylic acid, and 5-25% of a hydrophobic monomer, preferably a long chain alkyl (C.sub.8 -C.sub.24) acrylate, methacrylate, acrylamide or methacrylamide. The terpolymer has a K-value of 30-55, preferably 40-50, which provides compositions having good sprayability in both pump and aerosol form, and small, fine spray particles.
Claims7
A hair spray composition comprising, by weight,
- (a) about 2-10% of a terpolymer comprising:
- (i) about 60% to about 68% of vinyl pyrrolidone,
- (ii) about 20% to about 23% of acrylic or methacrylic acid, and
- (iii) about 9% to about 20% of lauryl methacrylate or stearyl methacrylate, having a K-value of 36-45,
- (b) 0-0.25% of a neutralizing agent,
- (c) 0-55% of alcohol,
- (d) 0-5% of adjuvants,
- (e) 0-35% of a propellant, and
