ABSTRACT
Skin cleansing liquids are products that clean and refresh the skin by removing soil or dirty materials to help keep the skin’s physiological condition normal. There are residual metabolites on the skin that are unstable and reactive with oxygen or deposited molecules by sun exposure or skin micro-organisms to form harmful materials to cause skin trouble. Thus cleansing is a necessary daily skincare practice even for normal skin. Furthermore, special care must be taken for sensitive skin or atopic skin because of its vulnerability. In these troubled types of skin, cleanliness must be attained without contributing to their susceptibility [1]. There are different types of cleansing products developed and commonly used depending on the types of materials to be removed from the skin or types of use conditions.
