Annotation Je obecně známo, že vliv tenzidových prostředků na Stratum corneum se liší podle jejich složení. Cílem této práce je porovnat účinek pěti komerčních sprchových gelů na hydrataci kůže. Tyto produkty se liší jak složením, přídavkem hydratačních látek, tak cenou. Pro srovnání jsou použity dodecylsulfát sodný a neošetřená pokožka. K měření míry hydratace je použit přístroj Corneometer CM 820. Dle výsledků je míra hydratace změněna po použití všech vzorků, avšak největší rozdíly mezi výrobky jsou zřetelné až po aplikaci vyšší koncentrace. Hydratace je sledována 26 hodin a asi po 24 hodinách je vidět samovolné obnovování přirozené hydratace kůže. Tato studie také poukazuje na to, že pouhé tvrzení na výrobcích a ani uvedené složení negarantují jejich účinek. Ten velmi závisí také na kvantitativním složení, které je ale pro konzumenta většinou neznámé.
Annotation in English It is well known that the effect of surfactant-based products on the Stratum corneum (SC) varies according to their composition. The present work aims to compare five commercial cleansing products with respect to their effects on the SC hydration. The products differ in ingredients, added moisturizing agents and price. Sodium lauryl sulfate (SLS) and untreated skin serve as reference controls. The skin capacitance is assessed by Corneometer CM 820. The samples induce the SC hydration in all cases, albeit to various extent. The results show marked differences among the samples only when higher concentrations are used. Nevertheless, the skin hydration tends to recover in one day after the application. This study shows that the claims on the products and listed ingredients do not guarantee their real efficacy as it depends also on the quantitative composition which is usually unknown to consumers.
