摘要：
An oral care composition, such as a toothpaste, comprising a film-forming polymer which is water insoluble and exhibits pH independent swelling, such as ethyl cellulose, poly (alkyl acrylate) (e.g. polymethyl acrylate) and poly (alkyl alkylacrylate) (polymethylmethacrylate) a first adhesive polymer which is water soluble, such as natural gum, synthetic gum, agar, multivalent salts of agar, polyalkylene glycol, carboxy alkyl cellulose, hydroxyalkyl cellulose and polyvinyl pyrrolidone a second adhesive polymer which is water insoluble and exhibits pH dependent swelling, such as alginic acid, multivalent salt of alginic acid, polyacrylic acid, salt of polyacrylic acid and an oral care active agent, such as a bleaching agent, a dental remineralisation agent, a dental desensitising agent, an anti-infective agent, an ant-caries agent, an anti-calculus agent, an anti-inflammatory agent and a biomolecule. Also disclosed is a process for the preparation of the oral care composition and a method of administering the oral care composition to teeth.
