CA 2386871
The invention provides personal care compositions which include polymers of isoprene, butadiene and/or styrene, particularly conjugated dienes which may be subject to some degree of hydrogenation. A copolymer of two different conjugated dienes is preferred. The polymers may be selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, thereby improving film forming properties.
La présente invention concerne des compositions de soins personnels qui comprennent des polymères d'isoprène, de butadiène et/ou de styrène, et en particulier des diènes conjugués qui peuvent être soumis à un certain degré d'hydrogénation. Un copolymère de deux diènes conjugués différents est préféré. Ces polymères peuvent être hydrogénés sélectivement de façon à produire des polymères qui présentent des quantités hautement maîtrisées d'insaturation, ce qui améliore les propriétés feuillogènes.
