Abstract
Abstract A visually clear dentifrice composition comprising about 20 to 70% by weight of humectant solids, about 5 to 50% by weight of an abrasive, and water, (a) the humectant solids comprising a hydrogenated hydrolyzed polysaccharide wherein said hydrogenated hydrolyzed polysaccharide contains 25% or less maltitol and at least about 30% by weight of oligosaccharides with at least three glucose units; (b) said abrasive being capable of: (i) cleaning and polishing human teeth without damaging said teeth, and of (ii) forming a clear gel when combined with the humectant system, (c) the amount of water and the distribution of the molecular weights of said hydrogenated hydrolyzed polysaccharide being such as to render the dentifrice composition translucent or transparent.
