Agents antiseptic

Some simple benzoates are also used as antiseptic agents. Salicylic acid esters are used as antibacterial agents and pain relievers. Analgesic balms, creams. 

Antiseptic Agent that kills or inhibits microbial growth but is not harmful to human tissue. 

In addition lo its use in making resins and adhesives, phenol is also the starting material for the synthesis of chlorinated phenols and the food preservatives BHT (butylated hvdroxytoiuene) and BHA (butylated bydroxyanisole). Penta-chlorophenol, a widely used wood preservative, is prepared by reaction of phenol with excess CI2- The herbicide 2,4-D (2,4-dichlorophenoxyacetjc acid) is prepared from 2,4-dichlorophenol, and the hospital antiseptic agent hexa-chlorophene is prepared from 2,4,5-trichlorophenol. 

Pharmacology The liquid contains sulfonated phenolics, which are antiseptic agents with topical analgesic properties, and sulfuric acid, which is a tissue denaturant and sterilizing agent. 

It is a local haemostatic and antiseptic agent. The haemostatic effect of feracrylum is based on the formation of synthetic complex consisting of its adduct with plasma proteins principally albumin. Like other biodegradable polymers, the feracrylum-albumin complex formed gets broken down over a period of time.

Anti-acids, astringents and antiseptic agents may contain a variety of aluminium salts. Organic salts, alumina, the hydroxide and phosphates may be attacked with concentrated hydrochloric acid and diluted to bring the aluminium concentration into the range 10—50 pg ml"1. Alternative procedures for antacids using hydrochloric/nitric acid [67] and extraction with 4M hydrochloric acid [95] have been proposed. For silicates, the sample is best taken up in perchloric/hydrofluoric acid, evaporated to dryness to remove silica, and then the residue dissolved in warm hydrochloric acid [87], In each case the nitrous oxide/acetylene flame is the preferred atom cell, and the method of standard additions may be used to minimise any errors arising from lateral diffusion. 

In another approach, the polymer is precipitated from the continuous phase onto on stable nanodroplets in an inverse miniemulsion [109], In this case, a miniemulsion with the liquid core material is formed in a continuous phase that consists of a mixture of a solvent and a nonsolvent for the polymer. That way, PMMA nanocapsules encapsulating an antiseptic agent could be produced.

Environmental contributions from pesticides, paints, antiseptic agents, thermometers, vacuum pumps, and a wide variety of other commercial, industrial, and pharmaceutical chemicals and products. 

Antiseptic agents are often used for the treatment of external ear canal disease. As with cerumenolytics, the presence of an intact tympanic membrane must be confirmed before their use. Some antiseptics are commonly used for otologic surgical prophylaxis. Antiseptic otologic preparations are marketed only as the acetic acid solutions. 

Thimerosal (Merthiolate) may also be used topically for the treatment of otomycosis. Considered bacteriostat, it is an excellent antiseptic agent in vitro against the common yeast and fungi responsible for otomycosis. ... 

Despite similar antibacterial composition, ototopical preparations may differ in delivery vehicle and pH level. Cortisporin Otic solution is the most acidic, whereas Coly-Mycin S Otic has a pH of 5, the highest of the group. The low pH of these compounds and the alcohol used as an antiseptic agent cause a burning sensation when in contact with the middle ear. 

Cetylpyridinium chloride is a quaternary ammonium cationic surfactant, used in pharmaceutical and cosmetic formulations as an antimicrobial preservative see Section 10. It is used therapeutically as an antiseptic agent used alone or in combination with other drugs for oral and throat care used in nonparenteral formulations licensed in the UK and used in oral and inhalation preparations at concentrations of 0.02-1.5 mg (see Section 16). 

The prodrug methenamine, described above in this chapter (Scheme S-17), can be considered a site-specific chemical delivery system for the urinary tract antiseptic agent fotmal-dehyde. The low pH of the urine promotes the hydrolysis... 

The antimicrobial properties of the resinous exudates from twigs and leaves of Eupatorium salvia Colla were tested against 5 Gram (-) and 5 Gram (+) bacteria [200]. Comparison of the antimicrobial activities of 7-hydroxy-8(17)-labden-15 oic acid (salvic acid) and its acetate, both compounds isolated from the plant, with that of the crude extract suggested that the latter ester derivative was the major active component in the exudates. These results validate the vernacular medicinal use of Eupatorium salvia as an antiseptic agent. 

Di- and trichlorinated benzenes were detected not only at sample sites mainly influenced by the Elbe river but also at sampling sites G and D, which are mainly influenced by input of the Ems river, with similar concentrations as in samples E and F (see Tab. 2). Hence these lower substituted compounds, which are used as synthetic raw material for many technical products such as antiseptic agents, solvents and additives (Biyant, 1993), are not appropriate marker compounds for tracing Elbe river derived contaminations. In contrast the tetra- to hexachlorinated benzenes, which have formerly been identified as contaminants in particulate matter of the Elbe river system (Schwarzbauer 1997, Schwarzbauer et al. 2001), appeared in the North Sea sediments only at sampling sites A,B,C,E and F (see Tab. 2). Fig. 1 illustrates the spatial distribution of hexachlorobenzene with concentrations between 2 and 50 pg/kg TOC in samples influenced by the Elbe river.
