Benzyl Alcohol

Benzyl Alcohol

Excellent Solvent Performance: Benzyl alcohol, as a medium-boiling-point solvent (205.4℃), exhibits excellent solubility for epoxy resins, coatings, and inks. Even small additions significantly improve system leveling and compatibility, effectively enhancing coating gloss and adhesion.


Unique and Mild Floral Fragrance: Benzyl alcohol emits a soft, slightly sweet jasmine-like fragrance. The aroma is pure, elegant, and long-lasting. In fragrance formulations, it acts as a fixative to stabilize the overall scent and imparts a fresh, natural floral base to soaps and cosmetics.


Multiple Flavors and Functions: In food flavorings, benzyl alcohol presents a sweet berry and nutty flavor with subtle fruity variations. It also possesses dual functions as a preservative and solubilizer. In pharmaceutical preparations, it effectively inhibits Gram-positive bacteria, achieving a synergistic effect of flavor and preservation.


Mature Synthetic Pathway: Benzyl alcohol can be efficiently produced through classic processes such as benzyl chloride hydrolysis or benzaldehyde reduction. The synthetic routes are mature and stable, with widely available raw materials, suitable for large-scale industrial production, ensuring consistent product quality and reliable supply.

Product Description

Benzyl alcohol product description CAS#100-51-6


Benzyl alcohol is a colorless, transparent liquid with a faint aromatic odor, slightly sweet and floral. Its melting point is -15.3°C and boiling point is 205.4°C, making it a medium-boiling organic solvent. Benzyl alcohol is slightly soluble in water (1:30) and miscible with organic solvents such as ethanol, ether, and chloroform in any proportion. Industrially, benzyl alcohol is mainly produced by the hydrolysis of benzyl chloride under alkaline conditions, and can also be synthesized through the catalytic reduction of benzaldehyde. This compound has good solubility and low vapor pressure, and is chemically stable at room temperature. Benzyl alcohol has a mild and long-lasting aroma, making it suitable for use as a solvent. Its unique fixative properties also enhance and harmonize the overall aroma in fragrance formulations. Furthermore, benzyl alcohol possesses certain antibacterial activity. These multiple properties make it valuable in the chemical, pharmaceutical, and food industries.

Benzyl Alcohol Applications CAS#100-51-6


Benzyl alcohol is an important organic solvent and chemical intermediate, widely used in coatings, inks, epoxy resins, and textile printing and dyeing auxiliaries. As a solvent or plasticizer, it effectively improves the leveling and adhesion of the system. In the fragrance industry, benzyl alcohol is a common raw material for formulating floral fragrances such as jasmine, gardenia, and tuberose, and acts as a fixative to prolong the fragrance's lasting effect. It is also used in food flavorings to formulate berry and nut flavors. In pharmaceutical preparations, benzyl alcohol is commonly used as a preservative (up to 2% concentration) and a solubilizer (approximately 5% concentration), effectively inhibiting Gram-positive bacteria and widely used in injectable and topical medications. In food contact materials, benzyl alcohol is listed in the positive list of EU Regulation 10/2011, allowing it to be used as an additive in plastic products. Furthermore, benzyl alcohol is used as a developer for photosensitive materials, a modifier for epoxy resin curing agents, and a raw material for organic synthesis. Its low toxicity and low volatility make it highly favored in various industrial applications.
