Phenyl salicylate
Description
Phenyl salicylate (CAS 118-55-8), commercially known as salol, is an ester used across pharmaceuticals, polymer stabilization, and fragrance applications. It functions primarily as a UV absorber, preservative, and flavoring agent depending on the end-use sector.
In plastics and polymer manufacturing, it absorbs UV radiation to protect resins and coatings from photodegradation, extending the service life of finished materials. This makes it a vital additive for industrial durability.
Pharmaceutical formulators use it as an enteric coating agent and intermediate, where its hydrolysis behavior controls active ingredient release in the gastrointestinal tract. It is often produced to meet USP or BP standards.
In personal care and cosmetic formulations, it contributes UV stabilization and mild preservative activity to sunscreens, creams, and topical products. Its versatility allows it to serve multiple functions in a single formulation.
At FEMA 3960, it is also approved as a flavoring agent in food and beverage applications, where it imparts characteristic aromatic notes. It may also be referenced under FCC guidelines for food-grade purity.
Phenyl salicylate is supplied as a white crystalline powder or flakes. It is available in pharmaceutical-grade and technical-grade specifications to meet the requirements of different regulated and industrial end markets.
Packaging options typically range from kilogram-scale bags to bulk drum quantities suited for industrial procurement volumes. Our supply chain ensures consistent quality and availability for global manufacturing needs.
