Carbopol 940 or Carbomer 940 Powder (and similar variants like B‑LOYAL Carbomer 940 High‑Quality Thickening Agent Powder) are raw material products containing Carbomer‑940, a highly efficient polymer used in a wide range of formulations.
Chemically, Carbomer‑940 is a cross‑linked polyacrylic acid polymer — basically a high‑molecular‑weight synthetic polymer made by linking acrylic acid chains together. It appears as a white, fluffy powder that swells and absorbs water.
