QUALITY CONTROL AND EVALUATION OF CERTAIN PROPERTIES FOR SOAPS MADE IN ROMANIA
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.
