This invention relates to polymeric liquid crystals prepared from a polysaccharide and a solvent, preferably water, which are used to deliver nutrients, perfumes, flavors, drugs and other ingredients in foods, cosmetics, household soaps, health care products e.g. bar or liquid soaps, toothpaste, shampoos, creams, and lotions and other preparations. The encapsulated active vehicle comprises: (a) from about 0.001% to about 60% of an active; and (b) from about 40% to about 99.999% of a stable polymeric liquid crystal consisting essentially of: (1) from about 10% to about 90% of a solvent; and (2) from about 10% to about 90% of a polysaccharide having a molecular weight of from about 500 to about 1,000,000. |
