Chronic exposure to mild irritants including cleansing and antiseptic products used for hand hygiene generates insults to the skin. To avoid unpleasant reactions, skin protection creams are commonly employed, but some fail to afford protection against a variety of xenobiotics. In this study, two skin protection creams were assayed comparatively looking for a protective effect if any against a liquid soap and an alcohol-based gel designed for hand hygiene in medical settings.
Corneosurfametry and corneoxenometry are two in vitro bioessays which were selected for their good reproducibility, sensitivity and ease of use. A Kruskal-Wallis ANOVA test followed by the Dunn test was realized to compare series of data obtained.
Significant differences in efficacy were obtained between the two assayed skin protection creams. One of the two tested creams showed a real protective effect against mild irritants, but the other tested cream presented an irritant potential in its application with mild irritants.
The differences observed for the two tested skin protection creams were probably due to their galenic composition and their possible interactions with the offending products. As a result, the present in vitro bioassays showed contrasted effects of the creams corresponding to either a protective or an irritant effect on human stratum corneum.
慢性接触包括用于手部卫生的清洁和消毒产品在内的轻度刺激物会对皮肤造成伤害。为了避免不良反应,通常会使用皮肤保护乳膏,但有些乳膏无法提供针对各种异源生物的保护。在这项研究中,我们比较了两种皮肤保护乳膏,以寻找它们对一种设计用于医疗环境手部卫生的液体皂和一种基于酒精的凝胶是否具有任何保护作用。
角质层表面张力测量法和角质层异源生物测量法是两种体外生物测定法,它们具有良好的重现性、敏感性和易用性。为了比较一系列数据,我们进行了 Kruskal-Wallis ANOVA 检验,然后是 Dunn 检验。
两种测试的皮肤保护乳膏之间的功效存在显著差异。两种测试乳膏中的一种对轻度刺激物表现出真正的保护作用,但另一种测试乳膏在应用于轻度刺激物时表现出刺激性潜力。
两种测试的皮肤保护乳膏之间的差异可能归因于它们的制剂组成及其与刺激性产品的可能相互作用。因此,本研究中的体外生物测定显示了乳膏的不同作用,对人体角质层既有保护作用,也有刺激性作用。
