Résumé : |
The project was conducted to evaluate the effect on the skin surface pH of application of surfactant systems of different pH.
Enhancement of the physiological stratum corneum pH leads to abnormal epidermal barrier function. Skin cleansing products are known to influence the skin surface pH. Studies have shown that various effects on the skin surface pH are related to a pH shift and restoration. Because of the varying results, a literature survey and a multicenter study were performed to evaluate the effect of skin cleansing on skin surface pH.
The literature survey was conducted on the topic "Influence of cleansing products on skin pH". Moreover, a controlled and randomized multicenter study was performed with 63 healthy male and female subjects. The skin surface pH was measured before and after a standardized washing procedure with three different cleansing products and water.
Publications since 1970 reveal different methods, conditions, panels and effects on skin surface pH. The changes in skin surface pH described after skin cleansing vary ±0 to +3.0 units. Biophysical measurements show that not only the product pH but also the combination of surfactants is a crucial factor in maintaining the natural skin pH.
Finding the optimal ratio of surfactants in combination with an acidic product pH between 4 and 5 will be an important challenge for cosmetic chemists in the future. |
