Title
(EN) DEPOSITION OF MATERIALS TO SURFACES USING ZWITTERIONIC CARRIER PARTICLES
(FR) DEPOT DE MATERIAUX SUR DES SURFACES A L'AIDE DE PARTICULES PORTEUSES ZWITTERIONIQUES
Abstract
(EN)
Compositions to deposit an active substance on a target surface (i.e. skin, hair). The active substance remains on the surface after the product is rinsed off the surface. The preferred deposition is from compositions containing an anionic or nonionic active in the co-presence of an anionic surfactant. The compositions contain carrier particles having a zwitterionic or cationic surface and a plurality of outwardly protruding filaments containing charged organocarbyl groups. The active substance is contained within the carrier particles.
(FR)
Compositions destinées à déposer une substance active sur une surface cible (par exemple la peau, les cheveux), cette substance active restant sur la surface après rinçage de celle-ci pour enlever le produit. Des compositions de dépôt préférées comprennent une substance active anionique ou non ionique en présence d'un tensioactif anionique et contiennent des particules porteuses possédant une surface cationique ou zwitterionique ainsi qu'une pluralité de filaments saillant vers l'extérieur et contenant des groupes d'organocarbyle chargé. Le principe actif est contenu dans les particules porteuses.
