Methpol polymers are highly efficient gel matrix formers for controlling drug release in solid dosage forms. The polymers have demonstrated slower drug release rates at lower concentrations than other commercially available excipients, enabling overall formulation cost savings and smaller tablet sizes.

The traditional grades are chemically Carbomers. These are cross linked polyacrylic acid polymer, available in white powder. They are rheology modifiers, capable to provide vast viscosity profile. They work at neutral pH and form sparkling clear gel, hydro-alcoholic gels and creams.

Methpol polymers can be used in oral care applications such as toothpastes and ulcer gels, desensitizing and whitening products. These polymers primarily function as efficient thickeners and co-binders at low usage level. The viscoelastic structure of Methpol polymers imparts shear-thinning rheology and low thixotropy, which enables a clean ribbon of toothpaste to be extruded from the tube.

Suspension of insoluble ingredients in oral and topical liquids/semisolids.
