Model: Carbomer Carbomer941

Chemical name: cross-linked polyacrylic resin

Molecular structure: - [-CH2-CH-]N-COOH

Features: It can produce low-viscosity emulsion and suspension, and the colloid produced by it has high transparency, and has better ion resistance in systems containing ions.

Product introduction: This product is an acrylic polymer cross-linked with polyalkenyl ether. It has strong hygroscopicity and certain acidity (because it contains carboxyl groups), and can be neutralized by alkaline substances to form a highly transparent gel. After the carbomer resin is neutralized to ionize the carboxyl group, due to the mutual repulsion of the negative charges, the molecular chain is diffused and stretched, showing a great expansion state and being viscous. Therefore, at a very low dosage, Carbo resin can produce high-efficiency thickening without being affected by temperature, and can make some insoluble additives (particles, oil droplets, etc.) permanently suspended.

This product is long flow, low viscosity, high clarity, low ion resistance and high shear resistance, suitable for clear gel and cream products.

Carbomer 941 is a white loose powder, which provides long-term emulsification and suspension effects under low viscosity conditions, even ionic systems. Relative ionic system. It is more effective at low concentrations than other types of carbomers. There is a gel with good clarity. It is used as an emulsion stabilizer in the cosmetic industry. It is used as a binder in solid dosage formulations and as a sustained release agent in the pharmaceutical industry.

Application fields:

Skin care lotion, styling gel, hydroalcoholic gel, moisturizing gel, shower gel, toothpaste, shampoo, shaving gel, moisturizing cream and sunscreen lotion, etc.

Precautions:

①After carbomer neutralization, long-term stirring or high-shear stirring will cause viscosity loss

②The presence of electrolyte will reduce the thickening efficiency of carbomer resin

③Long-term ultraviolet radiation will reduce the viscosity of carbomer resin
