Disinfecting detergent
A disinfecting detergent comprising 0.1-6% (w/w %) of hydrogen peroxide, 0.01-0.6% (w/w %) of peracetic acid, 0.01-2% (w/w %) of an ion-pair reagent and/or a phase transfer catalyst, 0.01-1% (w/w %) of a surfactant, 0.1-3% (w/w %) of a base, 0-1% (w/w %) of a stabilizer, and 90-96% (w/w %) of water, where the pH value of the disinfecting detergent is 7.1-9.9. The disinfecting detergent has the advantages of low toxicity, low corrosivity, no pungent smell and fast, broad-spectrum and high-efficiency sterilization, virus killing effect and spore killing effect.
DISPERSIBLE ANTIMICROBIAL COMPLEX AND COATINGS THEREFROM
Disclosed are latexes, suspensions, and colloids having a cationic antimicrobial compound complexed with an anionic surfactant. The surfactant may have greater affinity for the antimicrobial compound than other anionic surfactants and other anions in the latex, suspension, or colloid that contribute to disperse phase stability to prevent disrupting the dispersions. Dispersions containing the antimicrobial compound may therefore have a shelf life comparable to dispersions that are otherwise identical but lack the cationic antimicrobial compound and its complexed anionic surfactant. Coatings made with the complexes can exhibit essentially undiminished antimicrobial activity.
Water-repellent protective film, and chemical solution for forming protective film
A surface treatment was conducted by using a liquid chemical containing a water-repellent protective film forming agent represented by the following general formula [1], subsequent to a step of cleaning a metal-based wafer and prior to a step of drying the wafer. ##STR00001## (R.sup.1 represents a C.sub.1-C.sub.18 monovalent hydrocarbon group the hydrogen elements of which may partially or entirely be replaced with a fluorine element(s). R.sup.2 mutually independently represents a monovalent organic group having a C.sub.1-C.sub.18 hydrocarbon group the hydrogen elements of which may partially or entirely be replaced with a fluorine element(s). a is an integer of from 0 to 2.)
