Phenoxyethanol is an organic chemical used as a solvent in organic chemistry. It is commonly used in dermatology, bactericides, perfumery, and other industries. It is harmful if ingested, inhaled, or in contact with skin, but is useful as a stabilizing agent and biological buffer.
Phenoxyethanol is a chemical compound with a molecular composition that includes carbon, making it organic. It is used in organic chemistry as a glycol ether which acts as a solvent. This means that the compound can be used to dissolve solids, liquids or gases to obtain a homogeneous mixture or solution.
The atomic composition of this compound contains eight carbon atoms, ten hydrogen and two oxygen. Like an alkyl ether, its carbon and hydrogen atoms are arranged in a chain and connected to oxygen. It is also an ethylene glycol and contains two groups of hydrogen and oxygen. Due to the chemical makeup, the compound has a fairly high boiling point of 476°F (about 247°C).
Phenoxyethanol looks clear and has the consistency of an oily liquid. Physically it is highly stable unless introduced into acid chlorides, acid anhydrides or very strong oxidizing agents. When exposed to these materials, it will experience combustion. The molecule is also harmful if inhaled, ingested or if it comes into contact with the skin. It can also cause serious eye damage.
The molecule is most commonly used in the field of medicine known as dermatology. It has properties that make it useful for skin protection as well as providing healing factors. The most common dermatological products featuring the compound are suntan lotions and skin creams.
It is also commonly used in bactericides, solutions that are used to kill bacteria without harming other substances. When combined in this form, it is known as a quaternary ammonium compound, a negatively charged anion. Common examples of these are disinfectants, fabric softeners, shampoos, and spermicidal jellies.
In the field of perfumery, phenoxyethanol is used as a stabilizing agent. This is called a fixative in the industry and allows the final product to hold its fragrance for longer. The molecule substantially reduces the evaporation rate of the perfume, making it indispensable for the industry.
It is also heavily used by a variety of other industries. The compound is found in antiseptics, insect repellents, resins, dyes, inks, and a variety of pharmaceuticals. It can be used as a preservative to keep some foods fresh. Furthermore, being soluble in water, it can be used as an anesthetic for fish.
One of the most important aspects of its use is as a biological buffer in place of sodium azide. Phenoxyethanol is less toxic and also does not react to copper or lead. This allows you to turn it into an aqueous solution. When this solution is introduced into a second solution, the pH measurement is changed very little, which helps protect the overall acid or base level of the second solution.
