According to the literature data, the normal level of skin pH is of 4.7 [1]. However, many dermatologists would agree that the level of 5.5 is optimal, considering that the skin has a balanced level. When the skin suffers from a pH imbalance, the bacteria that protect the skin no longer work as well; thus, when the pH is alkaline, the skin is prone to eczema, and if it is too acidic, prone to acne [1]. It is advisable to choose cleaning products that have a pH similar to that of the skin (between 4.5 and 7), the pH differs slightly according to age. The soaps-cream combine delicate cleaning agents with moisturizing cream and offer gentle exfoliation and dead cells removal. Soaps-cream do not dry out the skin as ordinary soaps do [2]. Free acidity of cosmetic products is the percentage of free fatty acids found in the analyzed product and is conventionally expressed in the most representative fatty acid. For cosmetic products based on ordinary oils from soy, sunflower, peanuts and pumpkin, the free acidity is expressed in oleic acid (OA) [3]. The purpose of this work was to evaluate the free acidity of commercial soaps by direct titration of the samples with KOH (0.1N) solution in the presence of the phenolphthalein as indicator [4]. Two skin care cosmetics, cream soaps were used in the research: (1) cream soap ,,Purifying and creamy” and (2) soap ,,Dove”, beauty cream bar, ¼ moisturizing cream. According to the obtained results, cream soap „Purifying and creamy” has an acidity content expressed in oleic acid (OA = 5.08 ± 0.11%) of approximately 8 times compared to soap ”Dove”, beauty cream bar, ¼ moisturizer (OA = 42.1 ± 0.2%). The results are plausible as the sample of cream soap „Purifying and creamy” is proposed for babies with normal - dry skin. In conclusion, the pH value of skin cleansing products should be acidic and not neutral or alkaline and soaps containing fatty acid cream are ideal products for normal or dry skin.
