LC50 oral, rat; 1980 mg/kg MSDS.
LD50 Rabbit dermal 2250 mg/kg L2618.

2-Phenoxyethanol (PhE) has been shown to induce hepatotoxicity, renal toxicity, and hemolysis at dosages ? 400 mg/kg/day in subchronic and chronic studies in multiple species A32847.

The major hazards encountered in the use and handling of 2-phenoxyethanol stem from its toxicologic properties. Toxic by all routes (inhalation, ingestion, and dermal contact), exposure to this very faintly aromatic, colorless, oily liquid may occur from its use as a fixative for cosmetics, perfumes, and soaps; as a bactericide and insect repellant; as a solvent for cellulose acetate,dyes, stamp pad, ball point, and specialty inks; as a chemical intermediate for carboxylic acid esters (eg, acrylate, maleate) and polymers (eg, formaldehyde, melamine); and as a preservative for human specimens used for dissection and demonstrations in anatomical studies. Effects resulting from exposure to this substance can include eye irritation, headache, tremors, and central nervous system depression. If contact with the eyes occurs, irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes, and wash exposed skin thoroughly with soap and water. 2-Phenoxyethanol must be preheated before ignition can occur L2623.

Phenoxyethanol

small molecule approved

Deskripsi

Phenoxyethanol is a colorless liquid with a pleasant odor. It is a glycol ether used as a perfume fixative, insect repellent, antiseptic, solvent, preservative, and also as an anesthetic in fish aquaculture. Phenoxyethanol is an ether alcohol with aromatic properties. It is both naturally found and manufactured synthetically. Demonstrating antimicrobial ability, phenoxyethanol acts as an effective preservative in pharmaceuticals, cosmetics and lubricants L2619.

Phenoxyethanol (EU), or PE, is the most commonly used globally-approved preservative in personal care formulations. It is very easy to use in various types of formulations and is chemically stable. Phenoxyethanol is a colorless, clear, oily liquid with a faint aromatic odor at room temperature and a low water solubility and evaporation rate. It is produced by reacting phenol (EU) and ethylene oxide (EU) at a high temperature and pressure. This substance occurs naturally in green tea (EU) L2621.

According to the European Union Cosmetics Regulation (EC) n.1223/2009, phenoxyethanol is authorized as a preservative in cosmetic formulations at a maximum concentration of 1.0% L2625.

Phenoxyethanol has been classified as an antimicrobial and preservative by Health Canada L2623. It has also been used in vaccines and shown to inactivate bacteria, and several types of yeast A32838.

Profil Farmakokinetik

Waktu Paruh (Half-Life) -
Volume Distribusi A pharmacokinetic study of phenoxyethanol was performed using a mass spectrometry model for simultaneous analysis of phenoxyethanol (PE) and its major metabolite, phenoxyacetic acid (PAA), in rat plasma, urine, and 7 different tissues [L2629]. The absolute topical bioavailability of PE was 75.4% and 76.0% for emulsion and lotion, respectively. Conversion of PE to PAA was extensive, with the average AUCPAA-to-AUCPE ratio being 4.4 and 5.3 for emulsion and lotion, respectively. The steady-state tissue-to-plasma PE concentration ratio (Kp) was higher than unity for kidney, spleen, heart, brain, and testis and was lower (0.6) for lung and liver, while the metabolite Kp ratio was higher than unity for kidney, liver, lung, and testis and was lower (0.3) for other tissues [L2629].

Metabolisme

The fate of phenoxyethanol in rats and humans has been investigated L2618. The rate of intestinal absorption was rapid, with 60-70% of the excreted (14)C detected at 3 hours and > 95% of the total 4-day urinary (14)C detected within the first 24 hr. Trace amounts of radioactivity were detected in feces. Four days after dosing, only trace amounts of radioactivity remained in the carcass, primarily in the liver (< 0.2% of the dose), fat and muscle. At the 4 day point, the (14)C concentration in blood was measured to be only 0.001 L2618. The major metabolite of phenoxyethanol is phenoxyacetic acid L2629.

Rute Eliminasi

The fate of phenoxyethanol in rats and humans has been investigated. More than 90% of an oral dose of 16, 27 or 160 mg/kg body weight of (2-(14)C)phenoxyethanol administered to male Colworth rats by was excreted in the urine within 24 hours of administration. A female rat also excreted about 90% of a dose of 27 mg/kg body weight in the urine within 24 hours. About 2% and 1.3% of the ingested dose was recovered from the exhaled air of female and male rats, respectively L2618.
