Abstract:
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 carageenans. These solid and redispersible emulsions are used, in particular, in laundry care products.
