Abstract

Several medical soaps with antiseptic properties and washing commercial soaps were analyzed to compare the values on quality criteria for different characteristics.
A comparison of results on the pH, the content of total fat, free alkalinity/acidity, chloride content, foam height and alcohol insoluble with the quality criteria have shown clear differences. Values for pH ranged between 5.5 and 8, for free acidity between 0.06 and 0.88%, the chloride content from 0.16 to 0.5%, the level of foam between 4 and 115 ± 2 cm and alcohol insoluble located between 20-28%. The results were compared with the data in the literature. It can be concluded that the values determined are within the limits set by standards.
