Definitions
- the subject of the present invention is a perfuming system comprising a perfume encapsulated in an alkali-water-soluble organic polymer obtained by emulsion polymerization of ethylenically unsaturated monomers, its preparation process, its use as a perfuming agent in detergent compositions and detergent compositions comprising said system.
- Laundry detergents generally contain perfumes; it has been found that during their storage, the powdered detergents for washing machines in particular, lose from 20 to 90% of the perfume introduced, which requires the introduction at the start of very high quantities of perfume to maintain a sufficient scent at time of product use.
- the Applicant has found a perfume encapsulation system making it possible to release the perfume only essentially during the washing of the laundry.
- a first subject of the invention consists of a perfume system (SP) comprising a perfume in the molecular state encapsulated in particles (pAS) of an alkali-water-soluble organic polymer (AS) obtained by emulsion polymerization.
- SP perfume system
