940 Basic Carbomer Resin White Fluffy Powder For Cosmetics raw materials

Carbo resin, also known as carbomer, is a polymer formed by chemical cross-linking of acrylic acid or acrylate a, including polyacrylic acid and long-chain alkanol acrylate polymers. Its molecular structure contains acid groups, so it has a certain degree of acidity, has hydrophilic properties, and can be dissolved in water, ethanol and glycerin.

Carbomer powder

Carbomer has the functions of thickening, suspending, stabilizing the system, regulating the release of water and active substances, and has simple process and good stability. Therefore, it is a rheological modification widely used in personal care products, pharmaceuticals and other fields. Thickener.

1. Neutralization and thickening

Because it contains a certain amount of acid groups, it needs to be neutralized with alkali during application. After neutralization, the carboxyl group of the carbomer is ionized. Because of the mutual repulsion of negative charges, the molecular chain in it stretches into an expanded state, making it larger in volume, and thus has a thickening effect.

2. Hydrogen bond thickening

Carbomer molecules, as carboxyl donors, can combine with one or more hydroxyl groups to form hydrogen bonds to thicken. This reaction mechanism takes time. Commonly used hydroxyl donors are non-ionic surfactants, polyols and so on.
The performance and application of common carbomer series

Because of the difference in crosslinking degree and molecular weight, Carbomer will have a lot of different models, which can be divided into traditional series and new polymers. The different types of carbomers are used in different industries because of their different indicator capabilities. Let's take a look at the performance and application of several carbomers in the traditional series.
