1. Far more information about the effect of serum or other substances upon the germicidal action of soaps can be obtained by determining the germicidal titers over a wide range of pH than by determining the titer at a single pH. In this way a characteristic curve for each test substance is obtained. 2. The curve for a particular concentration of serum bears a definite relationship to the curve ...

IT WILL BE SEEN FROM THE ABOVE THAT WE HAVE STUDIED THE CONDITIONS ASSOCIATED WITH THE DEPOSIT OF CALCAREOUS SALTS: (I) in connection with normal and pathological ossification, and (2) in pathological calcification as exhibited in (a) atheroma of the vessels; (b) calcification of caseating tubercular lesions; (c) calcification of inflammatory new growth, and (d) degenerating tumors; and we have...

Vulvovaginal candidasis is a significant gynaecological infection, which causes extreme discomfort, such as vulvovaginal itching. Using modified agar well-diffusion method, this study therefore, investigates in vitro inhibitory / cleansing potentials of soaps, germicides and disinfectants on vulvovaginal Candida species, especially with regards to vulvovaginal itching. Crusader oil (100%), Meri...

A stud y has been made of t he effect of concentration on the surface tension, electrical conductance, p H , opacity, and foam fo rmation of aqueo us solutions of 30 typical commercial soaps and 6 p opular soapless detergent s. The soap s included t he following types: T oilet, " medicated," glycerin, coco, washing (laundry) , and shaving soaps. The results are exp lained on the basis of the co...

The study aimed to analyze the possibility of waste frying oil utilization in home-made soap production. Soaps were made from unheated and fried rapeseed, sunflower palm oils that had total polar material (TPM) values up 24%. Physicochemical microbial analyses performed on produced samples check their quality. hardness increased with degradation level rapeseed oils, opposite findings obtained f...

Soaps have been extensively used, often with added alkali, to emulsify or make soluble phenolic compounds of limited solubility (Klarmann, Shternov and Von Wowern, 1929; McCulloch, 1936). There is, however, a good deal of controversial information in the literature dealing with the effect of soaps on the germicidal action of phenolic compounds. Frobisher (1927) reported that small amounts of so...

Choline carboxylate surfactants are powerful alternatives to the well-known classical alkali soaps, since they exhibit substantially increased water solubility while maintaining biocompatibility, in contrast to simple quaternary ammonium ions. In the present study, we report the aqueous binary phase diagrams and a detailed investigation of the lyotropic liquid crystalline phases formed by choli...
