Description
Carbomer 940 is a synthetic high-molecular-weight polymer of acrylic acid, known for its ability to effectively thicken, stabilize, and emulsify formulations. It appears as a fluffy, white powder and is used in very low concentrations due to its high efficiency. When neutralized with a base, Carbomer 940 swells in water to form clear gels with excellent viscosity. It is prized for its ability to provide a smooth, non-tacky feel and to stabilize complex formulations, making it a staple in many cosmetic and personal care products.
Use
Carbomer 940 is commonly found in a wide range of personal care products such as facial gels, lotions, creams, shampoos, and styling products. It helps to create smooth, spreadable formulations with a pleasing texture and enhances the stability and viscosity of the product. Additionally, it is often used in pharmaceutical formulations, such as topical gels and creams.
Applications
Carbomer 940 is typically used in concentrations ranging from 0.1% to 1.0%, depending on the desired viscosity and texture. It is added to the water phase of formulations and then neutralized with a suitable base, such as triethanolamine (TEA), to achieve maximum thickening and gelation. The process involves hydrating the Carbomer in water, adjusting the pH, and then incorporating it into the final formulation. This ingredient is valued for its versatility, ease of use, and ability to produce clear, stable, and elegant gels and emulsions.
