Abstract
Moisturizers are mixtures of chemicals specifically designed to make the external layers of the skin (epidermis) softer and more pliable, by increasing its hydration (water) content and reducing evaporation. Loss of moisture in the stratum corneum causes dry skin and compromises its barrier function. Therefore, maintaining the hydration level of this layer is essential for healthy skin. For individuals who wash hands frequently or have dry skin (e.g. due to age or diabetes) using a moisturizer may be important. The personal care composition described herein provides a moisturizing system that does not have a negative effect on skin such as that which can be attributed to surfactants.
