Carbomer 940

Carbomer 940 is a white, fluffy, dry powder that is commonly used as a thickening agent, stabilizer, and viscosity enhancer in pharmaceuticals, cosmetics, and personal care products. It belongs to a class of synthetic polymers known as carbomers, which are cross-linked acrylic acid polymers.

Here are some key characteristics and uses of Carbomer 940:

1. Stabilizer: In addition to thickening, Carbomer 940 also acts as a stabilizer, helping to prevent emulsions and suspensions from separating over time. It improves the overall stability and shelf-life of formulations by enhancing their resistance to phase separation and syneresis.
2. Hydration and Lubrication: Carbomer 940 has the ability to absorb and retain large amounts of water, which can help hydrate and moisturize the skin when incorporated into topical formulations such as moisturizing creams and lotions. It also imparts a smooth, lubricating feel to the skin, enhancing the spreadability and sensory properties of products.
3. Drug Delivery: In pharmaceutical formulations, Carbomer 940 is used as a matrix for controlled drug release. It can encapsulate active ingredients and release them gradually over time, providing sustained therapeutic effects. This property makes it valuable in the formulation of topical gels, ointments, and transdermal patches.
4. Cosmetic Applications: Carbomer 940 is widely used in the cosmetic industry for formulating a variety of skincare, haircare, and personal care products. It is commonly found in moisturizing creams, hand sanitizers, hair gels, sunscreens, and toothpaste.
