Carbomer 940 is a high-performance, crosslinked polyacrylic acid polymer used primarily as a thickening agent, stabilizer, and emulsifier in various cosmetic, pharmaceutical, and industrial formulations. It is a white, free-flowing powder that forms a clear, gel-like consistency when dispersed in water. Carbomer 940 is widely used in products like lotions, creams, gels, and other aqueous formulations due to its ability to provide excellent viscosity and stability.

Versatile Applications in Cosmetic and Pharmaceutical Formulations

Carbomer 940 is extensively used in the manufacture of creams, lotions, gels, and ointments across skincare, haircare, and pharmaceutical industries. Its remarkable ability to form clear, stable gels makes it a preferred additive for enhancing texture and consistency while maintaining efficacy in product delivery.

Superior Thickening and Gelling Properties

As a high-performance thickening agent, Carbomer 940 delivers consistent viscosity and superior suspension capabilities. This ensures active ingredients remain distributed evenly, resulting in product stability and a desirable sensory profile for end users.

Safe, Stable, and Easy to Handle

Carbomer 940 is supplied as an odorless, tasteless white powder that is classified as a polymer and meets strict quality standards such as USP/NF. Its excellent shelf life is maintained when stored correctly, and its easy dispersibility in water simplifies manufacturing processes while reducing formulation challenges.

FAQs of Carbomer 940:

Q: How is Carbomer 940 used in cosmetics and pharmaceuticals?

A: Carbomer 940 acts as a thickening and gelling agent in cosmetics and pharmaceutical products. It is incorporated into creams, lotions, gels, and ointments to improve consistency and stability, enabling the even distribution and effective delivery of active ingredients.

Q: What are the main benefits of using Carbomer 940 in formulations?

A: The primary benefits include excellent thickening performance, high clarity gels, efficient stabilization of suspensions, and the ability to control product viscosity. These characteristics result in improved texture, feel, and effectiveness of the final product.

Q: When should Carbomer 940 be added during the formulation process?

A: Carbomer 940 should be dispersed in water at the beginning or middle stages of the formulation process. Once fully hydrated and swollen, it is neutralized to achieve the desired gel consistency before adding other sensitive active ingredients.

Q: Where should Carbomer 940 be stored to maintain quality?

A: Carbomer 940 should be kept in a cool, dry place, in a tightly sealed container. Proper storage conditions help preserve its high purity and prevent clumping or degradation over time.

Q: What is the process for dissolving and using Carbomer 940 in formulations?

A: To use, disperse Carbomer 940 powder evenly in purified water while stirring gently. Allow it to swell and hydrate fully, then neutralize with a suitable base (such as triethanolamine) to form a clear gel with the desired viscosity. This gel can then be incorporated into the final product.

Q: Is Carbomer 940 safe for use on skin and in personal care products?

A: Yes, Carbomer 940 is cosmetic grade and meets USP/NF standards. It is widely recognized as safe for topical use in skincare and personal care products, provided it is used according to established concentrations and guidelines.
