Abstract

The invention provides a non-aerated, foamable oral care composition comprising less than 1.5% anionic surfactant (by total weight anionic surfactant based on the total weight of the composition), abrasive cleaning agent and hydrophobin. The composition is mild to oral mucosa yet exhibits excellent foamability, texture and storage stability.

Description

field of invention [0001] The present invention relates to oral care compositions which exhibit enhanced mildness without compromising lathering ability, product texture or phase stability. Background of the invention [0002] Foam is a desirable characteristic of oral care compositions, such as dentifrices, because it allows the dentifrice to spread throughout the oral cavity and thoroughly contact the tooth surfaces during brushing. Compositions with good lathering ability are also preferred by consumers, as lathering provides a perception of effective cleansing of the composition. [0003] Good foaming ability is usually achieved in oral care compositions through the use of anionic surfactants. Sodium lauryl sulfate (SLS) is the most commonly used anionic surfactant for its foaming and surfactant action, and typical dentifrices contain up to 2 or 3% SLS (by weight based on total weight). [0004] In some cases, anionic surfactants such as SLS have been associated with m...
