Cosmetic chemicals refer to a diverse group of chemical compounds used in the formulation of cosmetics and personal care products. These chemicals serve various functions, including enhancing product stability, texture, and shelf life, as well as providing desired properties such as moisturization, UV protection, and color. Common cosmetic chemicals include emollients (e.g., oils and fatty acids), surfactants (e.g., detergents and foaming agents), preservatives, fragrances, and pigments. They are carefully selected and incorporated into cosmetic formulations to create products that cleanse, moisturize, beautify, and protect the skin, hair, and nails, catering to the wide range of consumer needs and preferences in the beauty and personal care industry.
