摘　　要：评价儿童沐浴使用抗菌皂及合成洗涤剂的pH值,以确认产品标签上是否有相关信息。对90种条状或液体样品进行定量、横断面及分析观测研究。这些样品包含67种儿童皂、17种抗菌皂及6种合成洗涤剂,每种样品均稀释至1%后测定。除了描述性统计外,考虑到最低5%的显著水平,使用了Pearson-Yates chi卡方检验和Student T检验进行了描述统计;另外,使用了Wilcoxon-Mann-Whitney检验、Fisher精确检验和Kruskal-Wallis检验进行推论统计。结果:液体产品和和条形产品的pH水平具有显著差异,其中液体产品pH偏低(4.4-7.9)(P<0.05),合成洗涤剂的pH较理想(微酸),而抗菌皂的pH最高,达到11.34(P<0.05)。其中只有两种产品在包装上标注了pH信息。本研究发现不同的产品p H值存在较大差异,因此,向医生及使用者提供其pH信息是非常有必要的。而且,为了保证皮肤的屏障功效,液体皂,尤其是合成洗涤剂,是目前最适合向诸如新生儿及婴幼儿等敏感皮肤推荐的产品。To evaluate the pH value of children＇s antibacterial soaps and syndets used in children＇s baths and verify whether there is information regarding pH on the product label. Methods： Quantitative, cross-sectional, analytical observational study that included ninety soap samples, both in bar and liquid presentations, as follows： 67 children＇s soap （group 1）, 17 antibacterial soaps （group 2）, and 6 syndets （group 3）. Each sample had its pH measured after 1% dilution. In addition to descriptive statistics, the Pearson-Yates chi-squared test and Student＇s t-tests were applied, considering the minimal significance level of 5%. The Wilcoxon-Mann-Whitney test, Fisher＇s exact test, and the Kruskal-Wallis test were used for inferential statistics： The pH levels varied considerably between liquid and bar presentations, with lower levels （4.4-7.9） found for the liquids （p 〈 0.05）. Syndets Showed pH levels close to the ideal （slightly acid） and the antibacterial soaps showed the highest pHevels （up to 11,34） （p 〈 0.05）. Only two of the soaps included in the study had information about their pH leVels On the product packaging. Knowledge of the pH of children＇s soap by doctors and users is important, considering the great pH variability found in this study. Moreover, liquid soaps, and especially syndets, are the most recommended for the sensitive skin of neonates and infants, in order to guarantee skin barrier efficacy.
