Description

Curoxyl® 42 is a patented micronized benzoyl peroxide dispersion (40%) in the form of a USP gel. Curoxyl® 42 can be the starting point for topically applied OTC anti-acne preparations. The advantage of Curoxyl® 42 is its small particle size which reduces the risk of irritancy and also gives a smoother feel on application. The gel is also easy to handle during manufacture, without the need for grinding or expensive safety equipment.

Formulation Guide

Incorporation of Curoxyl™42 in formulations:

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 the 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.

Cold process: This is easily used in cold processing of formulations where no heat is needed.

Note: When using a cold process, a temperature of 25°C is recommended.
