Dosage and advantages of different kinds of carbomer

Different carbomer have different performance, but the same generality. The appearance is loose white, slightly acidic powder, pH 2.5-3.0 (1% water dispersion). Carbomer can produce high efficiency thickening at low dosage (conventional dosage 0.25-0.5%), thus preparing emulsion, cream and gel with wide viscosity range and different rheology.

Common carbomer series

Carbopol940: recommended dosage: 0.2-1.0% short flow rheology, high viscosity, high clarity, low ionic resistance and shear resistance. It is suitable for gel and skin care emulsion, cream, alcohol containing transparent gel products, transparent skin care gel, hair styling gel, shampoo, shower gel.

Carbopol941: recommended dosage: 0.1-1.5% long flow, low viscosity, high clarity, moderate resistance to ion and shear resistance, suitable for gel and latex skin care emulsion, cream, transparent skin gel, hair styling gel (suitable for plasma formula).

Carbopol934: recommended dosage: 0.2-1.0% crosslinked polyacrylic acid resin, local use system, stable at high viscosity, used for gel, emulsion and suspensions. Skin care lotion, cream, opaque gel products, shampoo, shower gel.

Carbpol971: recommended dosage: 0.2-1.0% skin care emulsion, cream, alcohol containing transparent gel products, transparent skin care gel, hair styling gel, shampoo and bath.

Carbopol974: recommended dosage: 0.2-1.0% oral products include gel, anti allergy, whitening toothpaste, denture glue, transparent skin care emulsion, cream, transparent skin care emulsion, cream, gel, and transparent germicidal gel containing ethanol.

Carbopol980: recommended dosage: 0.2-1.0% crosslinked polyacrylic acid resin, local drug delivery system, crystal clear gel, water or alcohol solvent. Skin care emulsion, cream, alcohol containing transparent gel products, transparent skin care gel, hair styling gel, shampoo, shower gel.

0.0% of the polymer was emulsified by carbo2.0% in the system.

CarbopolETD2020: recommended dosage: 0.2-1.5% acrylate /C10-30 alkyl acrylate copolymer, long rheological, low viscosity, high clarity, high ion resistance and shear resistance, suitable for clear gel. It is mainly used in skin care emulsion, cream, transparent skin care gel, hair styling gel, shampoo and shower gel.

CarbopolUltrez21: acrylate /C10-30 alkyl acrylate cross linked copolymer, short denaturation, used in gel, washing and cleaning products, high electrolyte products, cream, emulsion.

Carbomer is a kind of acrylic polymer with polyether crosslinking. Although these resins are weakly acidic and weaker than acetic acid, they are easy to react to form salts. The pH value of these resins in water ranges from 2.8 to 3.2 depending on the resin concentration. The higher the concentration, the higher the concentration of carboxyl group, so the pH value is lower.

Carbomer polymer emulsifier is superior to general emulsifier

1. It is effective at a very low concentration of 0.1-0.5%, replacing the traditional surfactant dosage of 3-7%;

2. It is not limited by HLB value and pit;

3. Emulsifying any liquid oil at room temperature;

4. If the wax is melted in the manufacturing process, the wax can be emulsified;

5. Give full play to the role of surfactant in wetting, dispersing, adhesion, etc., and prepare stable emulsion;

6. It is easy to prepare waterproof emulsion without film-forming agent;

7. It can dissolve high oil phase into water to form (O / W) emulsion;

8. can be prepared: moisturizing cream, lotion, cleansing products, sunscreen products, alcohol free perfume, flavor conditioner (enhanced gloss, easy to comb), hand washing agents, low consistency spray emulsion and transparent microemulsion.
