(l) Cleaning cosmetics. Mainly including soap, shampoo, hair washing powder, bath lotion, shaving cream, cleansing cream, face mask, and floral water. These cosmetics need to be protected from moisture, heat, and pollution.
If soap gets severely damp, it may soften, spoil, exude oil or water. If exposed to sunlight for too long, its fragrance will dissipate. The longer the floral water is stored, the milder the alcohol smell becomes while the fragrance grows richer and more concentrated. However, attention should be paid to tightly closing the bottle cap to prevent air leakage and avoid direct sunlight.
(2) Nutritious and skincare cosmetics. There are many varieties. Classified by the cream structure, they include cold cream (including various nourishing creams and medicated creams), beauty cream, honey-based products, and anti-crack cream. Among them, cold cream is most vulnerable to freezing. Especially low-grade cold cream, if frozen severely, may result in cream separation and noodle-like phenomena. Excessive heat or sun exposure may cause the cream to dry out and degrade, losing its fragrance. Beauty cream, when heated, may result in oil-water separation. Nutritious skincare products must be protected from bacterial contamination; dirty hands should not be used to take the product, and the bottle cap should be tightened after use. Once the cream shows signs of mold, it may irritate the skin. Cosmetics for beautification mainly include powder, blush, lipstick, nail polish, perfume, eyeshadow, and mascara. Powder has a strong hygroscopic property; once damp, it will lump and discolor. Perfume and nail polish contain a large amount of volatile solvent; if the cap is not tightened after use, they will evaporate and dry out. Nail polish is also highly flammable and should be kept away from heat sources and open flames to prevent combustion.
(3) Hair care cosmetics. Including hair wax, hair milk, hair conditioner, hair oil, hair dye, and perm essence. They should all be stored in cool and ventilated places, avoiding heat sources to prevent heat-induced degradation and oil-water separation. Related articles:
