Chloroxylenol
Overview
Phenoxyethanol, also known as 2-phenoxyethanol, is an organic chemical compound widely used as a preservative in cosmetics and pharmaceuticals. It is valued for its antimicrobial properties and stability in formulations. Phenoxyethanol is also employed in industrial applications such as inks and dyes due to its solubility and low volatility. First synthesized in the early 20th century, phenoxyethanol has become a staple in personal care products, often replacing parabens in 'paraben-free' formulations. Its effectiveness against a broad spectrum of bacteria and fungi makes it a preferred choice for product preservation.
Physical and Chemical Properties
Phenoxyethanol is a colorless to pale yellow liquid with a mild, pleasant odor. It has a molecular weight of 138.16 g/mol and a density of 1.10 g/cm³. The compound is soluble in water, alcohol, and ether, making it versatile for various formulations. Its melting point is 14°C (57°F), and it boils at 247°C (477°F). Phenoxyethanol exhibits low volatility and good chemical stability, which contributes to its widespread use in products requiring long shelf lives. Its antimicrobial properties are effective at concentrations as low as 0.5-1.0%.
Main Applications
Phenoxyethanol is primarily used as a preservative in cosmetics, skincare, and haircare products. It prevents microbial growth in creams, lotions, and shampoos, extending product shelf life. In pharmaceuticals, it serves as a stabilizer for vaccines and topical medications. Industrial applications include its use as a solvent in inks, dyes, and coatings. Phenoxyethanol is also found in disinfectants and household cleaners due to its antimicrobial efficacy. Its mild odor and low toxicity make it suitable for consumer products.
Safety and Storage
Phenoxyethanol should be handled with care to avoid skin and eye contact. Proper ventilation is recommended during use, especially in industrial settings. It is classified as a mild irritant, and prolonged exposure should be avoided. Storage conditions include keeping the compound in a cool, dry, well-ventilated area away from heat sources and open flames. Containers should be tightly sealed to prevent contamination and evaporation. Disposal should follow local environmental regulations.
B2B Procurement Guide
When procuring phenoxyethanol, verify the supplier's compliance with international safety and quality standards such as ISO, FDA, or REACH. Request certificates of analysis (CoA) to confirm purity and composition. Bulk purchases typically offer cost savings, but ensure proper storage facilities are available. Consider logistics and transportation requirements, as phenoxyethanol is classified as a hazardous material in some regions. Establish long-term supplier relationships for consistent quality and pricing.
