Phenoxyethanol has germicidal and germistatic properties. [5] It is often used together with quaternary ammonium compounds.. Phenoxyethanol is used as a perfume fixative; an insect repellent; an antiseptic; [6] a solvent for cellulose acetate, dyes, inks, and resins; a preservative for pharmaceuticals, cosmetics and lubricants; [7] an anesthetic in fish aquaculture; [8] [9] and in organic ...
Phenethyl alcohol, or 2-phenylethanol, is an organic compound with the chemical formula C6H5CH2CH2OH. It is a colourless liquid with a pleasant floral odor. It occurs widely in nature, being found in a variety of essential oils. It is slightly soluble in water (2 ml per 100 ml of H2O), but miscible with most organic solvents.
Methyldibromo glutaronitrile. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Methyldibromo glutaronitrile (MDBGN) is a widely used preservative. It is made by reacting bromine with 2-methyleneglutaronitrile below 30 °C.
where R = an alkyl group. Parabens are chemicals that are commonly used as preservatives in cosmetic and pharmaceutical products. Chemically, they are a series of parahydroxybenzoates or esters of parahydroxybenzoic acid (also known as 4-hydroxybenzoic acid). Research is being conducted to evaluate the potential health implications of paraben ...
2-Hexoxyethanol is used by professional workers (widespread uses), consumers, in re-packing or re-formulation, in manufacturing, and at industrial sites. [2] It is used as high-boiling solvent. It also serves as an intermediate for neopentanoate and hexyloxyethyl phosphate. It serves as a coalescing agent in cleaners and latex paints.
Phthalates are produced industrially by the acid catalysed reaction of phthalic anhydride with excess alcohol.The synthesis of diethyl phthalate is illustrative of this: . The properties of the phthalate can be varied by changing the alcohol, [12] allowing for an almost limitless range of products, although only around 30 are, or have been, commercially important.
Octenidine dihydrochloride is a cationic surfactant, with a gemini-surfactant structure, derived from 4-aminopyridine. It is active against Gram-positive and Gram-negative bacteria. Since 1987, it has been used primarily in Europe as an antiseptic prior to medical procedures, including on neonates.
Phenoxyethanol was fermented to phenoxyacetic acid [16] in the tanks, which was then incorporated into penicillin via biosynthesis. Importantly, Brandl realised that phenoxymethylpenicillin is not destroyed by stomach acid and can therefore be given by mouth.
