The advantages of Carbomer in pharmaceutical preparations:
1) Linear release of drugs (Zero-order release kinetics)
2) Increasing bioavailability
3) Small dose supporting a slow release
4) Reducing cost
5) Increasing of formulation's selectivity
6) Reducing the size of troche
7) Good reproducibility of synthetic polymer
8) A lower tablet pressure can be suitable for a prepared troche
9) A good compatibility with fibers and other compositions

Carbomer940
Chemical Name: Cross-linked Polyacrylic Acid Resin
Molecular Structure: - [-CH2-CH-]N-COOH
Appearance: White loose powder
pH Value: 2.5-3.5
Moisture Content %: ≤ 2.0%
Viscosity: 40000~60000 mPa. S
Carboxylic acid Content %: 56.0_68.0%
Heavy metal (ppm): ≤ 20ppm
Residual Solvents%: ≤ 0.2%
Characteristics: It has a high viscosity and a good tackifying effect.
Range of Application: It is used for topical formulations and suitable for preparation of gels, creams and coupling agent. Carbomer and cross-linked acrylic resin as well as series products of these cross-linked polyacrylic acid are widely used at present and are often used in topical lotion, cream and gel. In a neutral environment, carbomer system is an excellent gel matrix with crystal appearance and nice sense of touch, so it is suitable for preparation of cream or gel. Besides, it has a simple process technique, a good stability, and you will feel comfortable after use, so it has achieved a wider application in the partial administration, especially in the skin and the gel for eyes. These polymers are used to optimize the rheological properties of aqueous solution.
