CHEMICAL COMPOUNDS antiseptics

Preservatives may inelude disinfeetant and antiseptic chemicals together with eertain compounds used almost exclusively as preservatives. They are added to mar industrial, including pharmaceutical, products which may, by their nature, support the growth of bacteria and moulds causing spoilage of the product and possibly infection of the user. In the field of pharmaceutical preservation, addition of an inhibitory substance to a multidose injection (Chapter 21) or the prevention of growth in aqueous suspensions ofdmgs intended for oral administration (Chapter 18) are prime examples. 

Uses Component of disinfectant formulations chemical intermediate for phenolic resins solvent for polyester fibers, antiseptic (veterinarian) preparation of 4-nitroso-2-methylphenol and other compounds. 

Uses A chemical intermediate in the manufacture of the pesticide 2,4-dichlorophenoxyacetic acid (2,4-D) and other compounds for use as germicides, antiseptics, and seed disinfectants.

Hydrogen peroxide (HOOH) is sold in drugstores as a 3% aqueous solution for domestic use and is marketed as a 30% aqueous solution for industrial and laboratory use. Because of its oxidizing properties, hydrogen peroxide is used as a mild antiseptic and as a bleach for textiles, paper pulp, and hair. In the chemical industry, hydrogen peroxide is a starting material for the synthesis of other peroxide compounds, some of which are used in the manufacture of plastics. 

In addition, iodine is also used for the manufacture of dyes and as a germicide. Simple iodine derivatives of hydrocarbons, such as iodoform (CHI3), have an antiseptic action. Organic compounds containing iodine have been used as rubber emulsifiers, chemical antioxidants, and dyes and pigments. 

ACGIH TLV TWA 0.03 mg(Mn)/m3 DOT CLASSIFICATION 5.1 Label Oxidizer SAFETY PROFILE Probably a skin, eye, and mucous membrane irritant. Flammable by chemical reaction with reducing agents. A powerful oxidizing agent. When heated to decomposition it emits toxic fumes of ZnO. Used as an antiseptic. See also MANGANESE COMPOUNDS and ZINC COMPOUNDS.
