Application
Carbomer is an important thickener. It is a high polymer crosslinked by acrylic acid or acrylate and allyl ether. Its components include polyacrylic acid (homopolymer) and acrylic acid / C10-30 alkyl acrylate (copolymer). As a water-soluble rheological modifier, it has high thickening and suspension properties, and is widely used in coatings, textiles, pharmaceuticals, construction, detergents and cosmetics.
Uni-Carbomer 940 is a crosslinked polyacylate polymer with strong moisturizing ability, acting as high-efficient & low-dosage thickener and suspending agent. It can be neutralized by alkali to form clear gel. Once its carboxyl group is neutralized, molecule chain expands extremely and viscidity comes up, due to mutually exclusion of negative charge. It can enhance yield value and rheology of liquid substances, thus it is easy to get insoluble ingredients(granual, oil drop) suspended at low dosage. It is widely used in O/W lotion and cream as favorable suspending agent.
Properties
1.High-efficient thickening, suspending and stabilizing ability at low dosage
2.Outstanding short flow (non-drip) property
3.High clarity
4.Resist temperature effect to viscosity
Applications:
1.Clear hydroalcoholic gel .
2.Lotion and cream
3.Hair styling gel
4.Shampoo
5.Body wash
Cautions:
Following operations are forbidden, otherwise result in loss of thickening ability:
– Lasting stir or high-shear stir after neutralization
– Lasting UV irradiation
– Combine with electrolytes
