Abstract

The present invention is a solid fabric care composition comprising a water-soluble carrier, a water-soluble polymer, a fabric care compound, a polysaccharide and a fragrance, wherein the water-soluble carrier is in particle form, having a coating comprising the water-soluble polymer and the fragrance, and a mixture of the fabric care compound and the polysaccharide being incorporated at least partly into the coating, or the coating of the water-soluble carrier being coated at least partly with a mixture of the fabric care compound and the polysaccharide. Also described herein are fabric care washing or cleaning products comprising the fabric care compositions.

First claim

We claim:

1. A method of manufacturing a dry granular fabric care composition comprising the steps of:
a. providing dry granular water-soluble carrier particles selected from the group consisting of inorganic alkali metal salts, organic alkali metal salts, inorganic alkaline earth metal salts, organic alkaline earth metal salts, organic acids, carbohydrates, silicates, and urea, and mixtures thereof;
b. melting a water-soluble polymer;
c. adding a perfume to said melted polymer to form a molten mixture;
d. mixing said molten mixture with said carrier particles to form at least a partial coating on said particles;
e. forming a dry mixture comprising a polysaccharide and a fabric care substance;
f. dusting said coated particles with said dry mixture while said coating remains at least partially molten.
