This paper is the first of a contemplated series of papers describing the germicidal action of various soap derivatives. The ordinary soaps are salts of fatty acids, the fatty acid radical consisting of a straight chain of carbon atoms to the first of which two oxygen atoms are attached, while the remainder are united to each other and to hydrogen. I t is possible to replace one or more of thes...

BACKGROUND Much has been written recently about the potential hazards versus benefits of antibacterial (biocide)-containing soaps. The purpose of this systematic literature review was to assess the studies that have examined the efficacy of products containing triclosan, compared with that of plain soap, in the community setting, as well as to evaluate findings that address potential hazards of...

Detailed studies of the bactericidal action of soaps have been made by numerous observers. Among them the most recent include those by Tilley and Schaffer, Walker, Eggerth, and Schaffer and Tilley. In general, such action increases with the number of carbon atoms in the fatty acid up to a maximum which depends upon factors such as the hydrogen ion concentration, the nature of the test organism,...

Soap may be defined as a chemical compound resulting from the interaction of fatty acids, oils and salt (Friedman & Wolf 1996). It is a cleaning agent made by the chemical action of alkali on fats or fatty acids to yield the sodium or potassium salts of these acids (Considine 1974). It possesses properties that may include wetting and emulsifying power, surface tension lowering and gel formatio...

The significance of calcium soap formation in the inhibition of calcium absorption has been studied in rats. 47Ca labelled soaps of fatty acids were introduced into the duodenum and the absorption of calcium measured after four hours in a whole body counter. The absorption of calcium was inversely correlated with the chain length of the fatty acid varying from 1% for Ca-stearate to 60% for Ca-h...

Two aspects of handwashing in hospital were considered. A study was carried out to examine the contamination of bar soap and containers, and the use of antiseptic soaps in reducing the resident flora of the skin. Swabs were collected from soap dishes on six wards and from a bacteriology laboratory on four consecutive days. The unmedicated bar soap was replaced by bar soap containing 2.5% povido...

Aquaculture plays a key role in achieving Sustainable Development Goals (SDGs), while it is difficult to accurately extract single-object aquaculture ponds (SOAPs) from medium-resolution remote sensing images (Mr-RSIs). Due the limited spatial resolutions of Mr-RSIs, most studies have aimed obtain areas rather than SOAPs. This study proposed an object-oriented method for extracting We developed...
