Publication number: 20230301302Abstract: A novel agrochemical formulation comprising adjuvants selected from diketopiperazines and an agrochemical active. A concentrate is also provided suitable for forming the formulation. The diketopiperazine provide adjuvancy in the concentrate and agrochemical formulations. There is also provided a method of making the formulation, and use of said diketopiperazines as adjuvants in agrochemical formulations is also provided. A method of obtaining the diketopiperazines from culturing of Metarhizium carneum, strain RKD0578 is also described. The extracted diketopiperazines may be used in a formulation for treating vegetation to control pests, or seed coating. Alternatively the strain RKD0578 itself may be used in a seed coating or in a formulation for treating vegetation to control pests.Type: ApplicationFiled: August 13, 2021Publication date: September 28, 2023Applicants: Croda International Plc, Croda, Inc.Inventors: Gregory James Lindner, Bradley Arnold Haltli, Russell Greig Kerr, Alyssa Louise Grunwald, Hebelin Correa Velandia

Publication number: 20230227489Abstract: Surfactants based on a newly discovered class of compounds include a hydrophobic lipid oligomer covalently linked to a peptide or peptide-like chain and a carbohydrate moiety, and a serine-leucinol dipeptide linked to the lipid oligomer. Such surfactants can be used to create an oil-in-water or water-in-oil emulsion by mixing together a polar component; a non-polar component; and the surfactant. Biosurfactants of the newly discovered class can be made by isolating and culturing a microorganism which produces the biosurfactant, and then isolating the biosurfactant from the culture. A microorganism can be engineered to produce biosurfactant of this newly discovered class by expressing a set of heterologous genes involved in the biosynthesis of the biosurfactant in the microorganism.Type: ApplicationFiled: January 20, 2023Publication date: July 20, 2023Applicant: Croda International PlcInventors: Russell Greig Kerr, Bradley Arnold Haltli, Douglas Hubert Marchbank, Fabrice Berrué

Patent number: 10898421Abstract: Use of pycnidione, epolone A, and epolone B as anti-dandruff actives either alone or in combination in anti-dandruff compositions, particularly shampoos and conditioners. The actives are particularly effective against Malassezia yeasts and Malassezia furfur. A method of obtaining pycnidione, epolone A, and epolone B from culturing of Neosetophoma samarorum is also described.Type: GrantFiled: June 8, 2016Date of Patent: January 26, 2021Inventors: Russell Greig Kerr, David Patrick Overy, Fabrice Berrué

Patent number: 10888548Abstract: Anti-Dandruff Agents A novel anti-dandruff composition comprising spirofuranone-lactam tetramic acid or derivatives thereof, and optionally at least one biologically derivable meroterpene. The spirofuranone-lactam tetramic acid is preferably a bio-active heterospirocyclic secondary metabolite of Aspergillus, such as pseurotin A. The biologically derivable meroterpene may be selected from fumagillin, fumagillin derivative, chlovalicin, or ovalicin. Use of said agents as anti-dandruff actives in anti-dandruff compositions, particularly shampoos and conditioners is also provided. The active is particularly effective against Malassezia yeasts and Malassezia furfur which may cause dandruff. A method of obtaining the anti-dandruff actives from culturing of Peyronellaea sp. strain RKDO347 is also described.Type: GrantFiled: June 8, 2016Date of Patent: January 12, 2021Assignee: Croda International PlcInventors: Russell Greig Kerr, David Patrick Overy, Fabrice Berrué
