  • Applications

    Chemical name: 2-((1-Ethylpentyl)oxy)acetic acid; CAS 92759-90-5 is typically used as an intermediate in the synthesis of fragrance ingredients and cosmetic additives, leveraging its glycolate ester functionality to access a range of polar lipophilic derivatives. It may serve as a solvent or processing aid in industrial formulations. In the polymer and plastics sector, it can act as a plasticizer or compatibility agent for polyesters and vinyl resins. In coatings and inks, it can function as a rheology modifier or processing additive to improve flow and leveling. It can also be a precursor for surfactant or cleanser formulations and emulsions, depending on formulation requirements and regulations.
