Carbomer(Carbopol) 940
Carbomer 940 is a high molecular weight polymer of acrylic acid cross-linked with allyl ethers of pentaerythritol. Carbomer 940, previously dried under vacuum at 80° for 1 h, contains NLT 56.0% and NMT 68.0% of carboxylic acid (–COOH) groups. The viscosity of a neutralized 0.5% aqueous dispersion of Carbomer 940 is between 40,000 and 60,000 mPa·s.

Carbomer model:

The numbers behind the carbomer model represent the viscosity model. Carbomer is composed of repeated structural units of acrylic acid, and the polymer chain is cross-linked with allyl sucrose or allyl pentaerythritol. The larger n is, the larger the molecular weight is and the greater the viscosity is.

  • Viscosity: 30500-39400

    It is suitable for suspension and emulsion in high viscosity gel, emulsion and ointment; Local application; Skin care; Hair care; Odor masking agent; Cream; Hand, body and face lotion. Widely used in pharmaceutical (ointment) formulas and cosmetic creams.

  •  

    Viscosity: 40000-60000

    It is suitable for thickening, suspension and emulsification in the formula of cosmetics or drugs. Such as: Shaping Gel, water alcohol gel, moisturizing gel, bath gel, toothpaste, shampoo, shaving gel, moisturizing cream and sunscreen lotion, etc.

  •  

     

     

    Viscosity: 4000-11000

    It is suitable for plasma systems in external lotion, cream and gel, cleaning gel and water-alcohol gel.
