Product Description:

Benzyl L-lactate is an organic compound derived from L-lactic acid and benzyl alcohol. It is a colorless to pale yellow liquid with a characteristic, mild, fruity, and slightly floral odor. Its structure features a chiral center, and the L-isomer is the naturally occurring form. Its primary and most significant application is as a fragrance ingredient and flavoring agent. In the cosmetics and personal care industry, it is valued for its pleasant, non-irritating scent and is used in perfumes, lotions, and other scented products. In the food industry, it serves as a synthetic flavoring substance, imparting creamy, buttery, or fruity notes to various food products. Benzyl L-lactate is also investigated as a chiral building block in organic synthesis, particularly for the preparation of other lactate esters or more complex molecules where the stereochemistry is important. It is generally considered safe for use in fragrances and flavors when used within established guidelines.
