The pH of the skin is slightly acidic (4.6 to 5.8) which is important for
appropriate antibacterial, antifungal, constitution of barrier function, as well
as structuring and maturation of the stratum corneum. This study aimed to
evaluate the pH of the main commercial moisturizers and liquid soaps in Brazil.
Thus, pH of the products was quantified by pH meter in three measurements. A
total of 38 moisturizers and six commercial liquid soaps were evaluated. Mean pH
of 63% and 50% of the moisturizing and liquid soaps presented results above 5.5,
disfavoring repair, function, and synthesis of dermal barrier.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
