  • Applications

    2-Ethylhexyl 7-methyloctanoate (CAS 71566-49-9) is a well-established ester used as a fragrance ingredient and light solvent across several industries. In perfumery and cosmetics, it commonly serves as a scent ingredient and a carrier/solvent to aid dissolution and dispersion of fragrance components. In household and consumer cleaning products, it can function as a solvent base or fragrance carrier to help release and stabilize aroma in formulations. Due to its fatty, relatively stable character, it is sometimes evaluated as a plasticizer or processing aid in polymer formulations and coatings, and can be used as an intermediate in chemical synthesis to access other esters. Actual usage is subject to local regulations and formulation limits.
