Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
Many of these tests are also highly dependent on the concentration of Silane-Quat in the formulation, the synthesis method (water or methanol) and the method of application. It has been found that under laboratory conditions, Silane-Quat performs best if it is synthesized in methanol and applied using an electrostatic sprayer.
In a 1998 study using the FDA protocol, a non-alcohol sanitizer with benzalkonium chloride as the active ingredient met the FDA performance standards, while Purell, a popular alcohol-based sanitizer, did not. The study, which was undertaken and reported by a leading US developer, manufacturer and marketer of topical antimicrobial ...
The bacteriostatic (prevent growth) or bactericide (kill microorganism) activity of DDAC depends on its concentration and the growth phase of the microbial population. [4] It is a broad spectrum biocidal against bacteria and fungi and can be used as disinfectant cleaner for linen, recommended for use in hospitals, hotels and industries.
The copper in the preparation is in the form of a soluble complex with ammonia NH 3 or an amine such as ethanolamine N(C 2 H 5)H 2.In any case, the copper content is usually expressed as a weight percentage of the amount of copper oxide CuO that would account for the copper present.
Medical iodophor (Chinese povidone-iodine solution) An iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or water-soluble polymers such as povidone (forming povidone-iodine), [1] [2] The result is a water-soluble material that releases free iodine when in solution.
