Abstract
A low volatile organic compounds hair spray microemulsion in the form of a stable, clear, single phase system in which the particles therein have a diameter of less than 1 micron, consisting essentially of, by weight, (a) an ethyl half-ester of a copolymer of maleic anhydride and an alkyl vinyl ether in an amount of less than 20%, optionally neutralized up to 20 mole %, (b) an ethoxylated glycerol fatty acid ester as the surfactant having a hydrophobic-lipophilic balance of 10-18, in an amount of at least 0.1%, (c) ethanol in an amount of 55% or less, and (d) water to 100%.
