ABSTRACT:
A visually clear gel dentifrice comprising a polishing agent having a refractive index of about 1.41 to 1.47, a substantially water-insoluble noncationic antibacterial agent, an aqueous water-humectant liquid vehicle having a refractive index with about 0.02 refractive index units of the refractive index of the polishing agent and surfactant which is a sulfated polyoxyethylene alcohol sodium or potassium salt or a weight mixture of at least 3:1 to sodium or potassium lauryl sulfate with the sulfated polyoxyethylene alcohol or a weight mixture of about 1:3 to about 3:1 of sodium potassium lauryl sulfate with an N-acyl-N-alkyl taurate sodium or potassium salt. The visually clear systems have reduced formation of surfactant crystals when subject to cool temperature.
