Process to form fabric softening particle, particle obtained and its use

摘要

This invention relates to the incorporation of single and double emulsions into a cross-linking polysaccharide matrix selected from alginate and carrageenan, particularly when cured in a saline solution. Beading and extrusion were used as encapsulation processes. Particles were obtained containing 54 to 88% oil. The double emulsion is known to deliver rinse conditioner softness to the wash. The problem has been to incorporate it into a matrix that will allow redispersion in the wash. The emulsions incorporated redisperse in the same manner as they did before incorporation. The technology has been tested for a wide range of oils, however, specific combinations of oils and kappa carrageenan yield excellent particles containing high oil levels, which are suitable for incorporation into detergent powders, with good softening performance.
