Butyl salicylate

Butyl salicylate (CAS 2052-14-4), also known by its FEMA 3650 designation, is an ester used primarily as a UV-absorbing agent and fragrance fixative in personal care formulations. It also functions as a flavoring ingredient in food and pharmaceutical applications where a mild, balsamic character is required. In sunscreens and skin care products, it enhances UV absorption.

This chemical helps stabilize other active ingredients, allowing formulators to optimize SPF performance. Fragrance manufacturers incorporate it as a fixative to extend the longevity of floral and oriental scent profiles. In pharmaceutical oral formulations and confectionery, it contributes a subtle balsamic, minty note recognized for use as a flavoring agent. It also functions as a solvent and carrier for active ingredients.

In topical pharmaceutical preparations, it improves spreadability and ingredient compatibility. The product is supplied as a clear, colorless to pale yellow liquid for industrial use. It is available in cosmetic-grade and pharmaceutical-grade specifications to meet the purity requirements of personal care and drug formulation markets. Packaging options typically include drums and bulk containers.
