Carbomer is a homopolymer of acrylic acid with a high molecular weight, which is cross-linked with any of several polyalcohol allyl ethers. Carbomer polymers are manufactured by cross-linking process. Depending upon the degree of cross-linking and manufacturing conditions, various types of Carbomer are available.
They are fluffy white powders that readily absorb water to form gels or thick solutions that are non-toxic, stable, and resist spoilage. It contains not less than 56.0percent and not more than 68.0percent of carboxylic acid (–COOH)groups. The PH value of 1.0% water dispersion is between 2.5 and 3.0. When it is neutralized with alkaline substance, it will change into gel with PH value between 5.0~10.0. The viscosity of a neutralized 0.5percent aqueous dispersion of Carbomer 934GE between 30.0~40.0 Pa.S. And the viscosity of Carbomer940GE is between 40.0~60.0Pa.s.
Properties
• T. Carbomer AD-0 products are excellent emulsion stabilizers, viscosity adjusters and
viscosity builders.
• n-Hexane is used as solvent in the polymerization step.
• T.Carbomer AD-0 products are soluble in both water and alcohol.
• T. Carbomer products can be used over a wide pH range application.
Application
• T® Carbomer AD-0 products are suitable for the preparation and stabilization of creams,
lotions and suspensions.
• T® Carbomer AD-0 is especially suitable for the preparation of clear water or alcohol
based gels.
• T® Carbomer AD-0 is recommended for the manufacturing of high viscous emulsions.
• T® Carbomer AD-0 is especially suitable for O/W creams.
Preparation
Add T® Carbomer slowly into the Vortex of the agitating liquid. Avoid agglomeration. Use dissolver or propeller stirrer or rotor-stator-homogenizer. Intensive shear may lead to a viscosity reduction of the final product and should be avoided. Neutralise with triethanolamine,
tetrahydroxypropylethylendiamine, sodium hydroxide or inorganic bases.
T® Carbomer products can also be dispersed directly into mineral oil or ester oils just before manufacturing.
