    Abstract: The present invention is directed to a process for the preparation of the saponification products of lactones, preferably three- to eight-membered lactones. The present invention is also directed to a process for the preparation of compounds having general formula (I): wherein M is selected from the group consisting of cationic species, preferably metal cations (even more preferably Na), from a compound having the formula (II): comprising reacting a compound having formula (II) with a suitable hydroxide salt (M-OH) (III) such as, preferably, sodium hydroxide, in an aqueous medium. The reaction preferably utilizes a continuous process method for the substantial consumption of reagent and continuous, semi-continuous, and/or batch-wise processing for final consumption of reagent.

    Abstract: The present invention relates to the manufacture of microparticle benzoyl peroxide. The process of the invention provides for an aqueous slurry of USP benzoyl peroxide, optionally containing additives, being processed via microfluidization technology. The process comprises forcing a slurry of benzoyl peroxide at high pressure through a narrow channel designed to produce high shear, thereby achieving primary particle size reduction in addition to de-agglomeration.
