Many people cannot find shampoo temporarily, and when they need to wash their hair, they will use facial cleanser to wash their hair. Don’t be fooled by the appearance of facial cleanser, which looks very similar to shampoo. In fact, they are completely different. Moreover, the ingredients and principles of shampoo and facial cleanser are different. Facial cleanser can only be used to wash the face and cannot be used to wash other things. Don’t mistake facial cleanser for shampoo in normal times. Facial cleanser cannot be used for washing hair and has no effect on cleansing or caring for hair. Facial cleanser is a high-grade face cleanser. A good quality facial cleanser should have the functions of cleansing, nourishing and protecting the skin. Generally speaking, ordinary facial cleansers do not have a whitening effect. If you add an appropriate amount of skin whitening agents (such as angelica, arbutin, V derivatives, placenta extract, arbutin, kojic acid and its derivatives, etc.) to a high-quality facial cleanser, it will have a whitening effect if used for a long time. Cleansing principle Generally speaking, facial cleanser is a paste product composed of oil phase, water phase, surfactants, moisturizers, nutrients and other ingredients. Among them, creamy facial cleansers contain oily ingredients and are suitable for dry skin; crystal-like transparent products do not contain oily ingredients and can meet the needs of most consumers if the formula is properly adjusted. Surfactants in facial cleansers have five major functions: wetting, dispersion, foaming, cleansing and emulsification, and are the main active ingredients in cleansing products. In addition, according to the principle of like dissolves like, during the face washing process, the oil phase can be used to dissolve the oil-soluble fat dirt and excess oil on the face; the water phase can be used to dissolve the water-soluble sweat stains and dirt on the face. Basic Types Foaming cleanser: It contains surfactants and is divided into two types: multi-foam type and micro-foam type. Surfactants are used to stabilize grease in water and dissolve it in water to achieve a cleaning effect. Soap facial cleansers are also one of these categories, but because of their obvious characteristics, they are generally treated differently from ordinary surfactant facial cleansers. Solvent-based facial cleansers: This type of product relies on the oil-oil dissolving ability to remove oily dirt. It mainly targets oily dirt, so they are generally some makeup remover oils, cleansing creams, etc. Foam-free facial cleanser: This type of product combines the characteristics of the above two types, using an appropriate amount of oil and containing some surfactants. |
