Carbomer 940

CAS: 9003-01-4

INCI: Carbomer 940

Chemical Structure:

• Carbomer 940 is a high-molecular-weight polymer of acrylic acid cross-linked with a polyalkenyl ether. It is a synthetic compound composed of acrylic acid monomers.

Physical Form:

• Carbomer 940 is typically supplied in a fluffy, white powder form.

Solubility:

• It is insoluble in water but can absorb and retain large amounts of water to form a gel-like consistency.

Function in Formulations:

1. Thickening Agent: Carbomer 940 is widely used as a thickening agent in cosmetic and pharmaceutical formulations. It imparts viscosity to formulations, giving them a gel-like or creamy texture.

2. Stabilizer: It helps stabilize emulsions, preventing the separation of oil and water components in formulations.

3. Suspension Agent: Carbomer 940 is effective in suspending solid particles in liquids, preventing settling or clumping.

4. Controlled Release Agent: In pharmaceutical formulations, it can be used to control the release of active ingredients.

Common Applications:

• Carbomer 940 is commonly used in the formulation of various skincare and personal care products, including creams, lotions, gels, and topical pharmaceuticals.

Usage Instructions:

• It is added to formulations in small amounts and requires proper dispersion to avoid clumping.
• Carbomer 940 is often neutralized with an alkaline substance (such as sodium hydroxide) to achieve its full thickening potential.

Compatibility:

• It is compatible with a wide range of cosmetic ingredients.

Benefits:

• Provides a smooth and consistent texture to formulations.
• Enhances the stability of emulsions.
• Enables the formulation of clear gels.

Considerations:

• Carbomer 940 can be irritating to the eyes, so precautions should be taken during the formulation process.

Regulatory Status:

• Carbomer 940 is considered safe for use in cosmetics and pharmaceuticals when used according to industry guidelines.
