Carbopol^® Polymers

Carbopol^® Powdered Polymers

Description

The numerous products within the Carbopol polymer family are chemically similar in that they are all crosslinked acrylic acid-based polymers. The products are crosslinked to different levels with a polyalkenyl polyether.

Numerous enhancements have been made to the Carbopol polymer family over time to address formulation demands, increase product robustness and improve product handling during processing. For example, the solvent system used to synthesize the polymers has evolved.

Specifically, the "traditional" polymers are synthesized in benzene and the "toxicologically preferred" polymers are synthesized in either ethyl acetate or a cosolvent ethyl acetate/cyclohexane mixture. Additionally, a minor processing aid has been incorporated in the Carbopol ETD (easy to disperse), EZ and Ultrez polymers to provide greater versatility in formulating and processing.

Advantages: Carbopol polymers are exceptional thickeners, suspending agents and stabilizers. They provide formulators with the ability to develop products with a wide range of flow and rheological properties.

Carbopol^® Liquid Polymers

Description

Most Carbopol polymers are supplied as a powder, except for Carbopol Aqua 30 polymer which is supplied as a 30% active polymer in water. Carbopol Aqua 30 is an alkali swellable, lightly crosslinked acrylic emulsion polymer.

Advantages: Carbopol Aqua 30 polymer is easy to use because it is supplied in liquid form. It enables formulation flexibility because of its surfactant compatibility and synergistic thickening with salts. Carbopol Aqua 30 polymer offers clarity and structuring in surfactant systems, excellent stabilization of low pH systems and enhanced vertical cling properties.
