Carbomer 934
INCI name: Carbomer
Carbomer 934 is a cross-linked polyacrylate polymer. It has excellent stability when the viscosity is high, and can form thick formula preparation, which is suitable for opaque gel, emulsion, cream and suspension. Carbomer 934 has short flow characteristics in aqueous system. Kabom U21 also has similar performance, but its application range is wider and easier to disperse.

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.
