Novel composition

a dentifrice and composition technology, applied in the field of dentifrice composition, can solve the problems of insufficient foaming in the oral cavity, many dentifrice additives which are incompatible with aqueous systems, etc., and achieve the effects of superior organoleptic properties, superior organoleptic properties, and improved mouthfeel

AI Technical Summary

Benefits of technology

The patent describes a new dentifrice composition that uses a combination of two types of surfactants, betaine and taurate or betaine and an alkyl sulphate, to improve its taste and mouthfeel. The combination of these surfactants results in a more consistent and dense foam compared to using just one single surfactant. This improvement is achieved without affecting the taste of the dentifrice.

Problems solved by technology

There are many dentifrice additives which are incompatible with aqueous systems of typical dentifrice formulations.
However when the paste was brought into contact with water during brushing there was insufficient foaming in the oral cavity.
This was thought to be due to the fact that the foaming agent (sodium lauryl sulphate) was “hindered” in the anhydrous mass and was unable to concentrate at the air-water interface during brushing to form air bubbles or foam.

Abstract

The invention relates to non-aqueous dentifrice compositions comprising a surfactant system. The surfactant system consists of a combination of surfactants i.e., a betaine and a taurate surfactant; or a betaine and an alkyl sulphate surfactant; or a betaine, a taurate and an alkyl sulphate surfactant.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a composition in particular to a non-aqueous dentifrice composition comprising a novel surfactant system. In particular the invention relates to a non-aqueous dentifrice composition comprising a combination of surfactants i.e. a betaine and a taurate surfactant; or a betaine and an alkyl sulphate surfactant; or a betaine, a taurate and an alkyl sulphate surfactant. Such a dentifrice composition demonstrates pleasant organolpetic properties and is of use in oral care.BACKGROUND OF THE INVENTION[0002]There are many dentifrice additives which are incompatible with aqueous systems of typical dentifrice formulations. One way of overcoming this incompatibility problem is to formulate such additives in a non-aqueous (anhydrous) formulation. However in addition to circumventing the water incompatibility problem, such formulations must also be successful from a consumer acceptance standpoint and demonstrate, for example, acceptable...
