Oral care compositions comprising a polyvinyl capralactam-polyvinyl acetate-polyethylene glycol graft copolymer, and methods for the same

Abstract

An oral care composition and methods for preparing the oral care composition are disclosed. The oral care composition may include a carrier and a structure-building agent. The carrier may be present in an amount of from about 0.01 wt% to about 99 wt%. The structure- building agent includes a polyvinyl capralactam-polyvinyl acetate- polyethylene glycol graft copolymers (PCA-PVA-PEG), and may be present in an amount of from about 0.01 wt% to about 60 wt%, based on a total weight of the oral care composition.

Description

Background technique [0001] Structure builders, also known as gelling agents, thickeners or thickeners, are commonly used in oral care compositions to increase their viscosity and provide a structure that holds the other components and ingredients of the oral care composition In a homogeneous state or in a chemically and / or physically stable environment. [0002] Structure builders can be hydrophilic or hydrophobic. Conventional hydrophilic structure builders (such as polyvinylpyrrolidone (PVP), Carbopol, etc.) can be used to provide a homogeneous structure to oral care compositions, while conventional hydrophobic structure builders (such as plastic gels) can be used to contain Oral care compositions with relatively high amounts of hydrophobic oils such as mineral oil. However, conventional structure builders fail to provide homogeneous or heterogeneous gels when the oral care composition or its carrier includes small amounts of water (eg, less than 10% by weight).
