example 1

[0096] A structure builder, polyvinylcaprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (PCA-PVA-PEG) was evaluated Efficacy for the preparation of oral care compositions in gel form. Generally, about 30 to about 50% by weight of PCA-PVA-PEG and about 50 to about 70% by weight of the different carrier (ie, liquid carrier) are combined with each other via speed mixing. After mixing, each gel mixture was brought to room temperature and evaluated. The results of the study are summarized in Table 1.

[0097] Table 1

[0098]

[0099] As shown in Table 1, PCA-PVA-PEG was able to form stable homogeneous gels with water, propylene glycol, polyethylene glycol 600, dimethyl isosorbide and triacetin. Therefore, PCA-PVA-PEG was able to form a well-structured gel matrix with water, propylene glycol, polyethylene glycol 600, dimethyl isosorbide, and triacetin. As further shown in Table 1, PCA-PVA-PEG was able to form heterogeneous gels with glycerol, sorbitol and plu...

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).
