Curoxyl™ 42 is a patented, aqueous based, micronized benzoyl peroxide dispersion (40%) in the form of a gel. Curoxyl™ 42 can be the starting point for topically applied anti-acne creams, anti-acne wipes, facial cleansers and medicated pet shampoo formulations. The micronized Curoxyl™ 42 particles allow the BPO to penetrate pores to attack P. acnes bacteria. Once Curoxyl™ 42 has made contact with the bacteria, the oxidizing effect of the particle eliminates bacteria.

Formulation Guidelines

To use Curoxyl™ 42 in formulations:

  • Cold process: Is easily used in cold processing of formulations where no heat is needed. Note: When using cold process, a temperature of 25o C is recommended.
  • Oil-in-water emulsions: After two phases have been combined and the emulsion has formed, cool the batch to 40o C - 45o C. Slowly mix in Curoxyl™ 42 with propeller agitation and continue cooling and mixing.
  • Gel based formulations: After polymer dispersion at 75o C-85o C, add desired ingredients, then add neutralizer if required: KOH or NaOH. When batch reaches 45o C, add Curoxyl™ 42 with mixing and cool to 25o C. Note: Benzoyl peroxide is a white powder that is insoluble in water, therefore only opaque water based gel formulations are possible.
