Description

Octyl (S)-Lactate is a high-purity, optically active ester derived from lactic acid and 2-octanol. This compound is valued for its role as a versatile chiral intermediate and a high-performance, skin-friendly emollient in advanced formulations. It is essential for manufacturers in the pharmaceutical, cosmetics, and specialty chemical sectors seeking enantiomerically pure building blocks or sophisticated functional ingredients.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Cosmetics & Personal Care: Acts as a premium emollient and skin-conditioning agent in high-end creams, lotions, and sunscreens, offering a non-greasy feel.
• Fragrance & Flavor Industry: Used as a solvent and carrier for delicate aromas, and as a flavoring agent due to its mild, characteristic odor.
• Polymer & Resin Modifier: Serves as a bio-based plasticizer or co-monomer to modify the flexibility and properties of biodegradable polymers.
• Green Solvent: Employed as an environmentally benign solvent in specialty chemical reactions and extraction processes.
• Food Additive: Functions as a flavoring agent and solvent in food-grade applications where the (S)-enantiomer is specified.
