carbomer

Description

Carbomer is a synthetic polymer widely used in cosmetic and pharmaceutical formulations as a thickening agent, emulsifier, and stabilizer. This high-molecular-weight, cross-linked polyacrylic acid derivative is known for its ability to form clear gels and provide viscosity control in various skincare products. Carbomer's unique properties allow it to swell in water, creating a three-dimensional network that imparts a smooth, non-greasy texture to formulations.

In skincare, carbomer is prized for its versatility and compatibility with a wide range of active ingredients. It helps to suspend and stabilize particles, ensuring uniform distribution of active components throughout the product. Carbomer's pH-dependent swelling behavior allows for the creation of pH-responsive formulations, which can be beneficial in targeted delivery systems.

This ingredient is generally well-tolerated by most skin types and is considered non-sensitizing and non-comedogenic. Carbomer's ability to retain moisture on the skin's surface makes it valuable in hydrating formulations. Its film-forming properties can also provide a temporary protective barrier, helping to reduce transepidermal water loss. Carbomer is typically used in concentrations ranging from 0.1% to 2%, depending on the desired viscosity and product type.
