Benzyl Alcoho
Multifunctional Applications:
Benzyl alcohol is employed across a diverse range of industries including perfumery, cosmetics, pharmaceuticals, and paint production, underscoring its broad functional utility.
Antimicrobial Efficacy:
It functions as an effective preservative in skincare and cosmetic formulations due to its antimicrobial and antiseptic qualities, which help extend shelf life and maintain product safety.
Favorable Safety Profile:
With low toxicity and mild characteristics, benzyl alcohol is considered a safe excipient for medical and personal care applications—including use in injectable medications.
Solubility and Stability:
It demonstrates good solubility in water and most organic solvents, along with high stability under varying conditions, enhancing its adaptability across numerous formulations.
Benzyl alcohol (CAS No. 100-51-6), also referred to as phenylmethanol, is a versatile aromatic alcohol utilized across multiple industrial sectors. In its pure form, it is a clear, colorless liquid with a mild, pleasant floral aroma reminiscent of hyacinth. Commercial or industrial grades, however, may exhibit a slightly bitter almond-like or sharper odor due to impurities.
It is widely applied as a solvent and intermediate in the production of perfumes, cosmetics, pharmaceuticals, paints, and varnishes. Additionally, benzyl alcohol functions as an effective preservative in skincare and cosmetic products owing to its antimicrobial and antiseptic qualities. Its favorable safety profile—low toxicity and mild nature—makes it suitable for use in personal care items and even injectable drug formulations. Furthermore, it serves as a flavoring agent in the food industry and is used in synthesizing certain plastics and resins.
