Patent

CA 2614578

The invention relates to a solid redispersible emulsion, which is comprised of an oil-in-water emulsion consisting of a laundry care constituent, which is encapsulated in an enclosure. This enclosure is stabilized by polyvalent metal ions and, initially, is water-insoluble and is rendered soluble by adding metal ions. The enclosure material is preferably a biodegradable material and, in particular, a polysaccharide, such as alginates, pectins or carrageenans. These solid and redispersible emulsions are used, in particular, in laundry care products.

L'invention concerne une émulsion solide redispersable qui est constituée d'une émulsion huile dans eau d'un constituant d'entretien de textile qui est encapsulé dans une enveloppe stabilisée par des ions métalliques polyvalents, tout d'abord insoluble dans l'eau puis devenant soluble dans l'eau par libération des ions métalliques. Le matériau d'enveloppe est de préférence un matériau biodégradable, notamment un polysaccharide, comme des alginates, des pectines ou des carraghénanes. Ces émulsions solides et redispersables sont notamment utilisées dans des produits d'entretien de textile.
