Benzyl Alcohol is a liquid ingredient that is colorless and has a pleasant aroma. It is generally used as a preservative in cosmetics and personal care products. Benzyl Alcohol has antimicrobial properties that make it effective at preventing the growth of bacteria, fungi, and other microorganisms in cosmetic formulations. It is often used in concentrations of 0.5% to 2% as a preservative in a variety of products, including shampoos, lotions, creams, and makeup. However, its use is limited to products that have a pH below 5.5, as it is not effective at higher pH levels. The chemical formula of Benzyl Alcohol is C7H8O, and it is commonly derived from natural sources such as flowers and fruits.

What is BENZYL ALCOHOL used for?

Benzyl Alcohol is an important and effective ingredient due to its antimicrobial properties and mild, pleasant scent. It is thus widely used in personal care and cosmetic products.
  • Skin care: It is primarily used as a preservative in products like creams, lotions, and serums. It prevents the growth of fungi and bacteria that can lead to spoilage and contamination of the product
  • Hair care: It also has the ability to stabilize formulations and help hair care products last longer. It also works effectively to decrease the viscosity, thus improving the texture and feel of the products

Additionally, it is used as a solvent in certain cosmetic formulations to help dissolve other ingredients and improve product consistency


Synthetically, Benzyl Alcohol can be made through several methods, including the hydrolysis of benzyl chloride with sodium hydroxide, the reduction of benzaldehyde with sodium borohydride, or the reaction of toluene with carbon monoxide and hydrogen gas in the presence of a catalyst. The resulting product is subjected to purification methods such as distillation to obtain Benzyl Alcohol.
