Abstract
Disclosed herein are oral care compositions comprising at least one phosphate/acrylate copolymer, at least one cationic antibacterial agent, at least one synthetic anionic linear polycarboxylate polymer, at least one surfactant, and zinc lactate. Also disclosed herein are methods for the treatment and/or inhibition of gum disease or halitosis comprising contacting the oral cavity with the oral care compositions disclosed herein, as well as methods of making the oral care compositions disclose herein.
Claims13
An oral care composition comprising:
- at least one phosphate/acrylate copolymer in an amount of from 2.5% to 4% by weight;
- at least one cationic antibacterial agent in an amount of greater than 0.03% and less than 0.1% by weight;
- at least one synthetic anionic linear polycarboxylate polymer in an amount of at least 1% by weight;
- at least one surfactant in an amount of from 1% to 2% by weight;
- and
- zinc lactate in an amount ranging from 0.1% to 0.5% by weight,
- wherein the at least one surfactant is a nonionic poly(oxyethylene)-poly(oxypropylene) block copolymer, and wherein the at least one cationic antibacterial agent is cetylpyridinium chloride, and wherein the at least one phosphate/acrylate co-polymer is a co-polymerized product of acrylic acid, methacrylic acid, and a mixture of 2-hydroxyethyl methacrylate phosphates of Formula 1:
- wherein n is 0, 1 and 2;
- wherein the oral care composition has a turbidity of less than or equal to 15 Nephelometric Turbidity Units at 25° C.
