A comparative evaluation of the effects of soaps and detergents on pH behaviour and lipids level on the skin surface and duration of their restitution was carried out. The studies were conducted in two groups. The first group of 32 persons used 1% solution of "BHP" soap, whereas the other one, composed of 31 persons, 0,5% solution of detergentpowder "POLLENA". PH measurements of skin were performed using pH--meter of Radelkis firm with a combined glass and calomel electrode. Lipids on the skin surface were determined by the Hodgson--Jones and Wheatly's gravimetric method. The evaluation of soap and detergent's effects on skin was based on the mean output and direct pH values of the skin surface, accidental and residual level of lipids, and comparison of the duration of these parameters restitution. The soap was found to alkalyse stronger than the detergent, and duration of pH restitution is longer after using the soap, whereas the detergent degreases the skin more intensively than the soap. Also restitution of lipid's jacket is slower after using the detergent.
对肥皂和洗涤剂对皮肤表面pH值行为、脂质水平及其恢复持续时间的影响进行了比较评估。研究分为两组进行。第一组32人使用“BHP”肥皂的1%溶液，另一组31人使用洗涤剂粉末“POLLENA”的0.5%溶液。使用Radelkis公司带有玻璃复合电极和甘汞电极的pH计对皮肤进行pH测量。皮肤表面的脂质通过霍奇森 - 琼斯和惠特利的重量法测定。对肥皂和洗涤剂对皮肤影响的评估基于皮肤表面的平均输出值和直接pH值、脂质的偶然和残留水平，以及这些参数恢复持续时间的比较。发现肥皂的碱性比洗涤剂更强，使用肥皂后pH恢复的持续时间更长，而洗涤剂使皮肤脱脂的程度比肥皂更强烈。使用洗涤剂后脂质层的恢复也更慢。
