Abstract:
The present invention provides a hair styling composition comprising (a) 1% to 10% by weight of at least one polymer comprising, as polymerized units, one or more monomers having at least one acid-functional group; (b) 99% to 90% by weight of a solvent mixture comprising: (i) 5% to 100% by weight of at least one volatile organic solvent; (ii) 95% to 0% by weight of water, and (iii) 0% to 80% by weight of at least one propellant; and (c) a neutralizer, wherein the mole ratio of said neutralizer to the acid-functional groups on said polymer (a) is from 0:1 to 1.2:1, and the neutralizer comprises: (i) 10% to 30% neutralization of the acid group of the polymer by tetrabutylammonium hydroxide, and (ii) 90% to 70% neutralization of the acid group of the polymer by aminomethyl propanol. More particularly, the polymer (a) may comprise, as polymerized units, (i) 30% to 75% by weight of one or more monomer that has refractive index of 1.490 or higher, (ii) 1% to 30% by weight of one or more acid-functional monomer, and (iii) 5% to 69% by weight of one or more additional monomer. The hair styling composition of the present invention has improved clarity and humidity resistance.
