Abstract
Abstract Clear stable gels are made from hydrogenated maltose containing starch hydrolysates having 25-94% maltitol, 5-30% sorbitol, and minor amounts of reducing sugars by the addition of amorphous silica gelling agents. These gels are useful in formulating cosmetics, pharmaceuticals, confections and food specialties. They are particularly useful in preparing clear gel toothpaste compositions.

A toothpaste composition comprising a non-crystallizing edible gel consisting essentially of a maltitol syrup which comprises 25-94% by weight maltitol, 5-30% by weight sorbitol, low molecular weight polysaccharides and non-fermentable sugars wherein said composition has no more than 0.05-2% by weight reducing sugars when said maltitol syrup ingredients are calculated on a dry basis and a maltitol/sorbitol weight ratio of no less than 2/1 said syrup having a total dissolve solids content of 60-80% by weight when calculated on a wet basis, 5-10% by weight of a gelling agent having a refractive index in the range of 1.33-1.5 selected from amorphorous silica having an average particle size ranging from 3-10 microns and a surface area in the range of 300-1000 square meters per gram and up to about 15% based on the weight of the total composition of functional ingredients selected from a group consisting of soluble soaps, detergents, coloring agents, flavoring agents, buffers, preservatives, fluorides, bactericides, antibiotics, astringents and polishing agents.
