Function
Thickening: Carbomer is widely used as a thickening agent in formulations such as gels, creams, and lotions. It helps increase the viscosity of the product, giving it a more substantial texture and improving its spreadability.
Stabilizing: As an emulsion stabilizer, Carbomer helps prevent the separation of oil and water phases in formulations. This ensures the uniform distribution of ingredients and enhances the overall stability of the product.
Emulsifying: Carbomer facilitates the formation and stabilization of emulsions, allowing for the blending of oil and water-based ingredients in formulations. This helps create homogeneous products with smooth and consistent textures.
Suspending: In pharmaceutical suspensions and topical formulations, Carbomer can be used to suspend insoluble active ingredients or particles evenly throughout the product. This ensures uniform dosing and distribution of the active components.
Enhancing Rheology: Carbomer contributes to the rheological properties of formulations, affecting their flow behavior and consistency. It can impart desirable characteristics such as shear-thinning or thixotropic behavior, improving the application experience and product performance.
Moisturizing: In cosmetic and personal care products, Carbomer may also have moisturizing properties, helping to hydrate and condition the skin or mucous membranes.
