- coloring materials hide blemishes and traces to make the skin look healthy and have a beautiful color tone.
- the coloring materials used in these cosmetics include organic synthetic coloring agents and natural pigments. It is divided into (natural color) and inorganic pigment (Inorganic pigment).
- Organic synthetic colorants are classified into dyes, lakes, and organic pigments.
- the dye is a compound that is soluble in water, oil, and alcohol, and has azo group as a chromophore group, and a lake is a type in which an insoluble metal salt is combined with a water-soluble dye.
- Natural pigments are extracted from plants, animals, and microorganisms, which have been used for a long time as additives in foodstuffs because they have less color expression than synthetic colorants, but have recently been reexamined as they are used in pharmaceuticals requiring safety.
- Inorganic pigments are classified into coloring pigments, white pigments, extender pigments, and pearlescent pigments.
- Pigmented pigments give color to cosmetics and white pigments control the covering power of the skin.
- the extender pigment is a diluent of the pigment pigment and plays a big role in adjusting the color tone and using the product and formulating the product such as spreadability and adhesion.
- pearlescent pigments are pigments having a special optical effect used to give a pearlescent luster to the color, to give an iris color or a metallic sheen.
- Constitutional pigments commonly included in cosmetics include talc, kaolin, silica, talc, sericite, calcium carbonate, magnesium carbonate, and silicic acid. anhydride) and the like to control the concentration of color, spreading and texture of the formulation.
