Phenol finds application in many industries and has been commercially synthesized on large scales. These disinfectants have to be used at relatively high concentrations of 2-4% against viruses but are extremely effective against bacteria at 0.5% even in the presence of high levels of … Phenol are widely used as antiseptic, disinfectant, anesthetic and household cleaning products. Phenolics are present in hospitals today. of water). 3M Phenolic Disinfectant Cleaner Concentrate Indications 3M™ Phenolic Disinfectant Cleaner Concentrate is a multi-purpose germicidal detergent proven effective by the AOAC Use-Dilution Method in 400 ppm hard water (calculated as CaCO 3) in the presence of 5% organic bioload (Fetal Bovine Serum).This product disinfects, cleans, and deodorizes in one labor-saving step. Chemicals - Phenol, Chloroxylenol Quaternary ammonium compounds ("quats") – These are effective low level In hospitals, phenol is commonly found in disinfectants used to sterilize medical equipment. (The original Lysol ® concentrate still uses phenol.) Phenol has been used to disinfect skin and to relieve itching. This type of modern phenol is often used as a terminal disinfectant in house cleaning. These products are best for disinfection of non-porous surfaces and non-critical devices. over 30% of disinfectants used in veterinary applications are based on phenols. of water) or a 1:83 solution (12 mL per 1 L or 1.5 oz per gal. A very small quantity of phenol is use as disinfectant in mouthwash and household cleaning products. All these substances are chemically based on the phenol molecule (Fig. The antimicrobial properties of phenol derivatives have improved over time. Learning Objectives. It also controls mold and mildew on hard surfaces. Black phenyle is very powerful and can effectively disinfect even when it is very dilute. Phenolics have been around for a long time. Uses of Phenol. (1) Other uses of phenol include as a slimicide, as a disinfectant, and in medicinal products such as ear and nose drops, throat lozenges, and mouthwashes. These values are higher than many other classes of disinfectant and make the Use Dilution Confirmatory Test seem pointless since with a phenolic disinfectant with a phenol coefficient (F.D.A. Approximately two-thirds of the total phenol produced worldwide is used to prepare reagents used in plastic manufacturing industries. However, there are many phenol-based materials used as disinfectants. Phenol Coefficient. This is by no means the only way by which a phenol works. Disinfectants are chemicals used to kill microorganisms. STERIS' LpH® III st Disinfectant is specifically formulated for the routine disinfection of hard, non-porous surfaces. At a use dilution of rate of 0.8% v/v (1:128), the LpH III Disinfectants kill a broad spectrum of common bacteria and fungi. PRECAUTIONS. Some phenolic compounds are sensitive to and may be inactivated by water hardness and, … alkyl, phenyl, benzyl, halogen) replaces one … People can use antiseptics to clean areas of broken skin, intact areas of skin, and mucous membranes. Furthermore, triclosan, a common disinfectant used in hand and oral hygiene applications has been shown to produce bacterial resistance upon repeated exposure. Phenol used as a slimicide (a chemical toxic to bacteria and fungi characteristic of aqueous slimes) is a type of disinfectant. There are two main reasons for this: 1. Phenol Disinfectant - 4385160 UPC: 010228351600 Weight: 15.5 oz - 439 g Product Type: Aerosols. Describe why the phenol coefficient is used; Compare and contrast the disk-diffusion, use-dilution, and in-use methods for testing the effectiveness of antiseptics, disinfectants… Glutaraldehyde-based formulations (>2% glutaraldehyde, caution should be exercised with all glutaraldehyde formulations when further in-use dilution is anticipated); glutaraldehyde (1.12%) and 1.93% phenol/phenate. Sir Joseph Lister used a phenol called carbolic acid as a surgery antiseptic in the 1800’s. A type of antimicrobial agent used as a disinfectant, called a phenol, uses a similar process to kill off bacteria on inanimate objects through the inactivation of their enzyme systems. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. Scotts Phenyle is a heavy duty outdoor cleaner, deodoriser and disinfectant. Lysol, Pine Sol). These are alarming factors in considering the usage of phenols. It is also used as oral analgestic and anesthetic. Moreover, phenol-based products are limited in that they can not be used in the proximity of neonatal areas, particularly isolettes, or other infant contact surfaces. 1. Disinfectants are important chemicals used for a variety of purposes 1. Concentrated phenol is a highly toxic, corrosive substance that is easily absorbed through the skin. However, in Germany, only 7% of veterinary disinfectants are phenolic (4). This product can be used to clean drains, toilets, paths, concrete, paving, outdoor furniture and wooden fences. It can work against fungi and viruses. (1) Sources and Potential Exposure Their usefulness in laboratories is limited, however, because they leave a sticky residue on surfaces following treatment. Black phenyle (sometimes written as phenyl) is a dark brown or black liquid that is manufactured as a powerful disinfectant. the most common phenol used, OPP, is considered moderately toxic and an indirect carcinogen. These are alarming factors in considering the usage of phenols. One glutaraldehyde-based product has a high-level disinfection claim of 5 minutes at 35°C. Phenolics – It is oldest known disinfectant for e.g. Champion Sprayon® Phenol Disinfectant precleans or decontaminates critical or semi-critical medical devices prior to sterilization or high-level disinfection. Keep out of reach of children. Phenol-containing products are used as chemical peels to remove skin lesions and treat severe pain. 2. Phenols Phenol solutions have been used for many years as a disinfectant. Hence, they are better described as “disinfectants.” When To Use Both A Cleaner And A Disinfectant If both cleaning and disinfection of a surface is required, then one employs a liquid containing both a cleaning agent (typically, a detergent) and a substituted phenolic disinfectant (o-phenylphenol, for example, which avoids the toxicity, carcinogenicity, and corrosive nature of pure phenol). Black phenyle is most often used in hotels, hospitals, military facilities, homes, and animal farms, among other places. A type of antimicrobial agent used as a disinfectant, called a phenol, uses a similar process to kill off bacteria on inanimate objects through the inactivation of their enzyme systems. Phenol in low concentrations is used as a disinfectant in household cleaners and mouthwash. Phenol is an antiseptic and disinfectant. Phenolic germicides are used to clean surfaces in hospitals such … Describe why the phenol coefficient is used; Compare and contrast the disk-diffusion, use-dilution, and in-use methods for testing the effectiveness of antiseptics, disinfectants, and sterilants; The effectiveness of various chemical disinfectants is reflected in the terms used to describe them. The phenol-based residue contamination on non-critical items after using a surface disinfectant can cause hazardous injury to tissue or mucous membranes with which they contact. It can also disrupt the cell wall of a microbe, causing the lysis, or bursting open of that cell, as well. Ethyl or isopropyl alcohol (70-90%) Furthermore, triclosan, a common disinfectant used in hand and oral hygiene applications has been shown to produce bacterial resistance upon repeated exposure. Following are some of the Uses of Phenol. Also can be used to disinfect kennels, poultry sheds and garbage bins. In fact it is the most cost-effective home disinfectant (sodium hypochlorite solution) is used to clean toilets, drains, surfaces, swimming pool. Phenol Disinfectant Report Card Phenol derivatives originate when a functional group (e.g. Historically, a chemical agent’s effectiveness was often compared with that of phenol, the first chemical agent used by Joseph Lister. Disinfectants Chlorine is the best disinfectant for use against A(H5N1) contamination. triclosan and chloroxylenol) are among the more commonly used antiseptics. Phenol is also used as an oral analgesic or anesthetic in products such as Chloraseptic to treat pharyngitis. We can broadly conclude that the cleaning products contain disinfectants and the healing products (for curing the living tissues) contain antiseptics.
