Curoxyl™42 is a patented, aqueous based, micronized Benzoyl Peroxide dispersion in the form of a gel. Curoxyl™ 42 is an effective replacement for traditional forms of BPO with a very low irritation potential.
Benzoyl Peroxide is used as an ingredient to reduce the number of acne blemishes, acne pimples, blackheads and whiteheads, one of the most effective choices for a topical antibacterial agent in the treatment of acne.

Formulation Guidelines
Oil-in-water emulsions: After the two phases have been combined and the emulsion has formed, cool the batch to 40°C -45°C. Slowly mix in Curoxyl™42 with propeller agitation and continue cooling and mixing.
Gel based formulations: After polymer dispersion at 75°C-85°C, add desired ingredients, then add neutralizer if required: KOH or NaOH. When batch reaches 45°C, add Curoxyl™42 with mixing and cool to 25°C.
Note: Benzoyl peroxide is a white powder that is insoluble in water, therefore only opaque water based gel formulations are possible.
