Low VOC hair spray resin compositions containing homogeneous terpolymers of vinyl pyrrolidone, vinyl caprolactam and 3-(N- dimethylaminopropyl) methacrylamide are described. The hair spray compositions are made using a solution of the terpolymer which is clear and low in viscosity, and which provides a spray of relative small particle size. The hair spray compositions exhibit an effective high humidity curl retention property.
Compositions de laques pour cheveux à base de résine et à faible teneur en C.O.V. (composés volatiles organiques), contenant des terpolymères homogènes de pyrrolidone vinylique, de caprolactame vinylique et de 3-(N-diméthylaminopropyle) méthacrylamide. Ces compositions de laques sont élaborées à partir d'une solution de terpolymère transparente et de faible viscosité, laquelle donne une laque dont les particules sont de taille relativement petite. Ces compositions de laques possèdent des qualités qui les rendent efficaces pour fixer les boucles dans des conditions de forte humidité.
