Abstract
Perfume is absorbed within organic polymer particles which have a further polymer at their exterior. The further polymer incorporates free hydroxyl groups and serves to promote deposition of the particles from a wash or rinse liquor. The further polymer may be part of an encapsulating shell, but more conveniently is used as a stabilizer during polymerization of the particles. Highly hydrolyzed polyvinyl alcohol is preferred.
