The ingredients of modern lip service may also surprise those who use them: Lipstick, for example, can contain the shimmery substance of fish scales called "pearl essence". Pearl essence is obtained primarily from herring and is one of many by-products of large-scale commercial fish processing. This is rarely used due to the high cost and extreme fragility of this type of colorant. The primary source of the pearlescent shine used for warm and cool shades for lips, eyeshadows, and blush is mica, a natural, mined mineral. The mica, which is translucent, is coated with a very thin layer of titanium dioxide. This coating causes color to appear through interference effects with the mica; varying the thickness of the titanium dioxide changes the color of luscious lips. The red color of lipstick can come while lip service from iron oxide (rust) or from organic pigments. Typically, the pigment is crushed very finely while being mixed with castor oil. This pigment mixture is then mixed with a wax base to form a finished lipstick for luscious lips. The red color of some eyeshadows is from the dye carmine, made from the crushed bodies of the cochineal insect. This is extremely expensive and is used as rarely as possible. Pure carmine dye is usually more expensive than gold. Cosmetic colorants for warm and cool shades for lips are highly regulated. In the US, the regulating body is the Food and Drug Administration. Each country or group of countries has their own regulatory agency that controls what can go into lip service cosmetics. Many colorants in lip service cosmetics are also used as food dyes. Pearlescence of solid and liquid mixtures (eg. lipsticks for luscious lips) is achieved by adding a suspension of tiny flakes of a suitable material, often a wax, eg. glycol distearate. Lipstick contains a variety of waxes, oils, pigments, and emollients, used for lip service. The wax gives lipstick its shape and ease of application for warm and cool shades for lips. Among the waxes are beeswax, a substance obtained from bee honeycombs that consists of esters of straight-chain monohydric alcohols with even-numbered carbon chains from C24 to C36 and straight-chain acids also having even numbers of carbon atoms up to C36. Other waxes include carnauba wax used for luscious lips, which is an exudate from the pores of leaves of Brazilian wax palm trees. Candelilla wax, which is obtained from the candelilla plant and is produced in Mexico by immersing the plants in boiling water containing sulfuric acid and skimming off the wax that rises to the surface. In recent years, ingredients such as moisturizers, vitamin E, aloe vera, collagen, amino acids, and sunscreen have been added to lipstick. The extra lip service components keep lips soft, moist, and protected from the elements.
