Abstract: This specification relates to a process for preparing a purified human milk oligosaccharide (“HMO”) from an HMO-containing solution (e.g., a fermentation broth) by a process comprising mixed bed ion exchange, and a product of such a process.

Abstract: Compositions comprising mevalonolactone, mevalonic add, mevalonate, salts of mevalonic acid, mevalonolactone monohydrate, or any combination thereof and methods of use are provided for topical application for skin care, skin supplement, hair care, and oral care. More specifically, the present disclosure is directed towards compositions comprising mevalonolactone, mevalonic acid, mevalonate, salts of mevalonic acid, mevalonolactone monohydrate, or any combination thereof for providing a skin care benefit and/or multiple skin care benefits.

Abstract: Compositions and methods are provided for producing crystalline forms of organic acids or salts or lactones thereof from an aqueous solution. More specifically, methods are provided for producing a crystalline form of a salt of mevalonic acid (also referred to as X-MVA) from an aqueous solution, comprising subjecting the aqueous solution comprising said X-MVA to a purification step to produce a purified solution and crystallizing said X-MVA from said purified solution by water solvent crystallization. Methods are also provided for producing mevalonolactone from an aqueous solution comprising X-MVA, comprising subjecting the aqueous solution comprising said X-MVA to cation exchange thereby converting said aqueous solution comprising X-MVA to an aqueous solution comprising mevalonolactone (MVL). Methods are also provided for producing mevalonolactone monohydrate crystals.
