Abstract
Substantially dry, rehydratable, water-dispersible, gel-forming, porous hydrocolloid micro-particulates containing internally or internally and externally at least one water-soluble, non-gelling, hydration enhancing hydrocolloid, processes and intermediates for their preparation, and their uses.
Claims22
Substantially dry, rehydratable, water-dispersible, gel-forming, porous hydrocolloid microparticulates comprising:
- A) a gel-forming hydrocolloid which comprises the matrix of the porous microparticulates;
- and
- B) at least one water-soluble, non-gelling, hydration-enhancing hydrocolloid;
- wherein the component A) matrix contains component B) internally within its porous structure, and wherein component B) can also be present as a full or partial coating on the outer surfaces of the microparticulates.
