Carbomer 680 is a highly cross-linked polyacrylic acid polymer. This product exhibits shear-thinning flow characteristics and possesses relatively high viscosity. It can generate highly effective thickening and suspension properties even at low concentrations, making it widely utilized in cream and gel formulations.
Carbomer 680 is a cross-linked acrylic polymer. The polymer has short rheological properties and relatively high viscosity. It is widely used in systems such as transparent gels and creams, and can form crystal clear water-based or hydroalcoholic gels. It is particularly suitable for exfoliating gels, mud creams and other fields.
Carbomer 680 is an acrylic polymer with polyalkenyl ether cross-linking. It has strong hygroscopicity and certain acidity (because it contains carboxyl groups), and can be neutralized with alkaline substances to form highly transparent gels. After the carbomer resin is neutralized and the carboxyl groups are ionized, the molecular chains are diffused and stretched due to the mutual repulsion of negative charges, showing a greatly expanded state and viscosity. Therefore, at a very low dosage, the carbomer resin can produce an efficient thickening effect without being affected by temperature, and can make some insoluble additives (particles, oil droplets, etc.) permanently suspended.
High thickening effect: Carbopol 680 can significantly increase the viscosity of liquids at very low dosages. This characteristic makes it an ideal choice for developing cost-effective formulations.
Carbomer 680 not only has high-efficiency thickening, but also makes the liquid system pseudoplastic, that is, the viscosity decreases when shear force is applied, and returns to its original state after the shear force is removed.
Carbomer 680 can effectively suspend insoluble substances and particles. This ability is essential for the preparation of lotions, creams, gels and other preparations containing suspended particles.
