  • Patent number: 11193087
    Abstract: A process for making a surfactant composition is disclosed. In the process, a mixture comprising a sugar alcohol and fatty is formed. The mixture contains less than 5% by weight of water based on the total weight of the mixture. The mixture is reacted with an alkylene oxide to make a surfactant composition containing an alkoxylated sugar alcohol fatty acid ester and a polyalkylene glycol fatty acid ester. A surfactant composition and use of the surfactant composition to separate an oil phase and/or an aqueous phase from an emulsion is also disclosed.
    Type: Grant
    Filed: January 8, 2018
    Date of Patent: December 7, 2021
    Assignee: Croda, Inc.

  • Publication number: 20210204541
    Abstract: Spray drift reductants for agrochemical formulations and methods for reducing spray drift in agrochemical formulations are disclosed. An agrochemical formulation may comprise at least one spray drift reductant comprising a fatty acid ester of a C3 to C8 polyol, or an oligomer thereof having from 2 to 5 repeat units. The formulation also comprises at least one agrochemical active and/or nutrient, and optionally, a clathrate compound. A sprayable agrochemical formulation may comprise 0.01 wt. % to 1.0 wt. % of a spray drift reductant that is non-ionic, non-self-emulsifiable, has a hydrophilic-lipophilic balance of less than 7, and is capable of reducing spray drift by at least 10%, and also comprises at least on agrochemical active and/or nutrient, and optionally, a clathrate compound.
