Phenoxyethanol is chemical preservative, a glycol ether often used in dermatological products such as skin creams and sunscreen. It is a colorless oily liquid. It is a bactericide (usually used in conjunction with quaternary ammonium compounds), often used in place of sodium azide in biological buffers because phenoxyethanol is less toxic and non-reactive with copper and lead. It is used in many applications such as cosmetics, vaccines and pharmaceuticals as a preservative.
It is also used as a fixative for perfumes, an insect repellent, a topical antiseptic, a solvent for cellulose acetate, some dyes, inks, and resins, in preservatives, pharmaceuticals, and in organic synthesis. It is moderately soluble in water. It is used as an anesthetic in the aquaculture of some fish.
It is also listed as an ingredient for many United States vaccines by the Center for Disease Control. In Japan and the EU, its usage level in cosmetic products is restricted to concentrations of up to 1%.
The Food and Drug Administration has warned that the chemical is toxic to infants via ingestion, and "can depress the central nervous system and may cause vomiting and diarrhea." Combined with Chlorphenesin, these two chemicals can cause respiratory depression in infants. Since these chemicals are often present in cosmetics and lotions applied to the hands and are easily ingested, caution should be exercised.
German research in 1999, concluded that it had neurotoxin potential, but in a concentration-dependent manner.
The EPA (Environmental Protection Agency) data sheets show chromosomal changes and genetic mutation effects in testing as well as testicular atrophy and interference with reproductivity in mice for other glycol ethers, although phenoxyethanol is not mentioned in the abstract.
