SUMMARY Antiseptics and disinfectants are extensively used in hospitals and other health care settings for a variety of topical and hard-surface applications. Phenol (5-10%) was the first disinfectant commonly used. Phenol is also used as an oral analgesic or anesthetic in products such as Chloraseptic to treat pharyngitis. For those reason, phenol itself is not used as an antiseptic. Furthermore, little is Compounds derived from acetic acid.

Phenols and Related Compounds Phenolic compounds used as antiseptics or disinfectants include pure phenol and substitution products with halogens and alkyl groups. In the present study, we evaluated the mechanism of action of thymol against Salmonella ser. The phenol derivatives did not cause leakage of significant amounts of radioactivity from heat‐treated cells, and cells exposed to n‐butanol (which breaks the osmotic barrier) did release additional radioactivity when treated with p‐chloro‐m‐xylenol or phenol, but the total counts … Phenol derivatives originate when a functional group (e.g., alkyl, phenyl, benzyl, halogen) … In the 1860s, British surgeon Joseph Lister (1827–1912) began using carbolic acid, known as phenol, as a disinfectant for the treatment of surgical wounds (see Foundations of Modern Cell Theory). lysol/phenol toxicity and disadv.

Read "Studies on the mechanism of action of phenolic disinfectants II. A wide variety of active chemical agents (biocides) are found in these products, many of which have been used for hundreds of years, including alcohols, phenols, iodine, and chlorine. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. In the absence of water, coagulation will not occur. These aspects are the subject of this review. International Journal of Antimicrobial Agents 2007, 29 (2) , 217-222. Introduction Considerable progress has been made in understanding the mechanisms of the antibacterial action of antiseptics and disinfectants (215, 428, 437).By contrast, studies on their modes of action against fungi (426, 436), viruses (298, 307), and protozoa have been rather sparse.Furthermore, little is known about the means whereby these agents inactivate prions (). A thorough understanding of the mechanisms of DBP formation allows microbial inactivation goals and DBP control goals to be successfully balanced.
