Chemical Overview:
Benzyl salicylate丨CAS 118-58-1 is an aromatic ester formed by the esterification of salicylic acid with benzyl alcohol. It is a colorless to pale yellow oily liquid, known for its pleasant floral, balsamic fragrance and UV-absorbing properties. It is widely used in the fragrance and cosmetic industries and occasionally in other specialty chemical applications.
Applications
Fragrance and Perfume Industry
Benzyl salicylate is one of the most popular fragrance ingredients due to its mild, sweet floral aroma reminiscent of jasmine and heliotrope. It is used in:
Fine perfumes and colognes: Provides a smooth, warm, and slightly sweet note.
Personal care products: Incorporated in lotions, shampoos, soaps, deodorants, and aftershaves to impart fragrance.
Aroma blends: Often used as a fixative to help stabilize and prolong the scent of other more volatile fragrance components.
Cosmetics and Skincare Products
Beyond its fragrance use, benzyl salicylate acts as a UV light absorber, protecting products from photodegradation. Applications include:
Sunscreens and sunblocks: Helps absorb UVB rays, enhancing the sun protection factor (SPF).
Skin care formulations: Used in creams and lotions to improve product stability and protect sensitive ingredients from UV damage.
Hair care products: Protects hair formulations from UV-induced degradation and preserves fragrance integrity.
Flavoring Agent
Benzyl salicylate丨CAS 118-58-1 can be used in very small quantities as a flavoring agent in the food and beverage industry, providing sweet, floral, or balsamic notes in flavor formulations.
Plasticizers and UV Stabilizers
In some specialty industrial applications, benzyl salicylate serves as a plasticizer or UV stabilizer in polymers, helping to improve flexibility and resistance to UV damage.
Benefits
Pleasant Fragrance and Fixative Properties
Benzyl salicylate's sweet floral aroma makes it a valuable ingredient in perfumery, providing depth and complexity. It also acts as a fixative, slowing the evaporation of more volatile fragrance molecules, thereby extending the life of a scent.
UV Protection
Its ability to absorb UV radiation allows benzyl salicylate to protect formulations and packaging materials from photodegradation, enhancing shelf life and performance of cosmetic and personal care products.
Versatility
It blends well with a wide variety of other fragrance ingredients and is compatible with many cosmetic formulation bases, offering formulators flexibility in product development.
Low Toxicity and Skin Compatibility
When used within recommended concentrations, benzyl salicylate is generally considered safe and non-irritating to the skin, making it suitable for widespread use in consumer products.
Enhances Product Stability
By protecting sensitive ingredients from UV damage and oxidation, benzyl salicylate helps maintain the efficacy and appearance of finished products over time.
Summary
Benzyl salicylate丨CAS 118-58-1 is a multifunctional aromatic ester widely used in the fragrance and cosmetic industries. Its key attributes include a pleasant floral scent, UV-absorbing properties, and fixative effects that enhance product performance and longevity. These qualities make it indispensable in perfumes, personal care formulations, and some specialty industrial applications. While generally safe, it is used with consideration of allergenic potential in sensitive consumers.
