A substance that inhibits the growth of microorganisms such as bacteria and mold, preventing spoilage. There are preservatives for food, cosmetics, and medicines, as well as industrial preservatives for wood, textiles, leather, etc. They are added to items to be preserved to suppress the physiological activity of microorganisms and inhibit their growth, thereby preventing deterioration of the items and preserving them. Since many preservatives are somewhat toxic, preservatives for food, cosmetics, medicines, etc. must be used in a way that is harmless to humans, and the scope and amount of preservative use are regulated by law. Benzoic acid, sodium benzoate, sorbic acid, and sodium dehydroacetate are widely used as food preservatives, while parabens ( p -hydroxybenzocyanate esters) and phenoxetol (2-phenoxyethanol) are widely used in cosmetics and medicines. For wood, there is creosote oil. Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
