  • Publication number: 20230248677
    Abstract: Formulations containing biologically-produced, high-purity R-mevalonolactone are provided for modulating the expression of genes and metabolism related to epidermal turnover, hyaluronic acid synthesis, barrier function, anti-aging elasticity, extracellular matrix degradation, inflammation, stress, and pigmentation in human skin. The biologically-produced, high-purity R-mevalonolactone may be used as an ingredient in pharmaceutical, food, or cosmetic products and may be applied topically or ingested for modulation of gene expression and metabolism.

  • Patent number: 11492339
    Abstract: A process is provided for converting mevalonic acid into various useful products and derivatives. More particularly, the process comprises reacting mevalonic acid, or a solution comprising mevalonic acid, in the presence of a solid catalyst at an elevated temperature and pressure to thereby form various biobased products. The process may also comprise: (a) providing a microbial organism that expresses a biosynthetic mevalonic acid pathway; (b) growing the microbial organism in fermentation medium comprising suitable carbon substrates, whereby biobased mevalonic acid is produced; and (c) reacting the biobased mevalonic acid in the presence of a solid catalyst at an elevated temperature and pressure to yield various biobased products.

  • Publication number: 20220010091
    Abstract: Described herein are solvents and co-solvents comprising anhydromevalonolactone (aMVL) and various industrial applications for such solvents. aMVL has a number of advantageous properties for use in solvent, including high boiling point, low melting point, low viscosity, non-flammability, water solubility, exceptionally low volatility, and excellent solvation capability. Exemplary industrial applications for solvents comprising aMVL include polymer manufacturing, polymer recycling, mold production, fiber production, membrane manufacturing, thermosetting paint manufacturing, coating manufacturing, coating removal, paint strippers, cleaning products, degreasing products, nitrile synthesis, alkylation, production of syngas, carbon-carbon cross-coupling reactions, metal organic framework synthesis, halogenation reactions, formation of pharmaceuticals, formation of fungicides and/or herbicides, seed treatment products, bioregulators, and electrolytes in batteries or capacitors.

  • Publication number: 20200369827
    Abstract: Described herein polymer precursor compounds (aka polymer building blocks) of derived from biobased compounds, and specifically biobased mevalonolactone and its related derivatives. Through oxidation these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols and polyamides, as well as precursors for glycidyl esters and omega-alkenyl esters. Through reduction, these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols, polycarbonates, as well as precursors for glycidyl ethers and omega-alkenyl ethers. Through nucleophilic ring opening and/or amidation, these biobased precursors can be reacted to yield building blocks for polyester polyols, chain-extender for polyurethanes, or polyester-amides.
