Overview
Phenethyl alcohol is an aromatic alcohol derived from benzene, characterized by a pleasant rose-like scent. It occurs naturally in essential oils of roses, carnations, and other flowers, though it is commonly synthesized for industrial use. The compound is valued for its dual role as a fragrance and a preservative, making it indispensable in cosmetics and food industries. In perfumery, phenethyl alcohol serves as a base note, contributing to floral bouquets. Its antimicrobial properties also make it a popular choice for extending the shelf life of personal care products. As a flavoring agent, it is used in beverages and confectionery to impart a subtle floral note.
Physical and Chemical Properties
Phenethyl alcohol is a colorless liquid with a density slightly higher than water. It has a melting point of -27°C and boils at 219-221°C, making it stable under typical storage conditions. The compound is miscible with water, alcohol, and oils, which enhances its versatility in formulations. Its aromatic structure includes a hydroxyl group attached to a phenylethyl moiety, contributing to both its fragrance and solubility. The antimicrobial efficacy stems from its ability to disrupt microbial cell membranes, a property leveraged in preservative applications.
Main Applications
The primary use of phenethyl alcohol is in the fragrance industry, where it is a staple in floral perfumes and soaps. Its rose-like aroma is often blended with other notes to create complex scents. In cosmetics, it acts as a preservative, particularly in lotions and creams, to inhibit bacterial growth. The food industry utilizes it as a flavoring agent in products like candies and alcoholic beverages. Pharmaceuticals employ it as an excipient or solvent in topical formulations due to its mild antiseptic properties. Its broad applicability underscores its importance across multiple sectors.
Safety and Storage
While phenethyl alcohol is generally safe, prolonged exposure can cause skin or eye irritation. Proper handling includes using gloves and goggles, especially in industrial settings. It should be stored in tightly sealed containers away from direct sunlight and heat to prevent degradation. Regulatory bodies like the FDA and EU Cosmetics Directive approve its use within specified concentration limits. For bulk storage, stainless steel or glass containers are recommended to avoid contamination. Always consult safety data sheets (SDS) for specific handling guidelines.
B2B Procurement Guide
When sourcing phenethyl alcohol, prioritize suppliers with ISO or GMP certifications to ensure quality. Key specifications to verify include purity (≥98%), odor consistency, and absence of impurities like benzene residues. Bulk buyers should negotiate pricing based on volume, with discounts typically available for orders exceeding 100 kg. Logistics considerations include temperature-controlled transport for large quantities to maintain stability. Sample testing before large-scale procurement is advisable to confirm compliance with application requirements. Reliable suppliers often provide technical support for formulation integration.
