Verbpigments
From Wiktionary under the GNU Free Documentation License. A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colourants, usually ground into a fine powder. This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion. The worldwide market for inorganic, organic and special pigments had a total volume of around 7.4 million tons in 2006. Asia has the highest rate on a quantity basis followed by Europe and North America. In 2006, a turnover of 17.6 billion US$ (13 billion euro) was reached mostly in Europe, followed by North America and Asia. A distinction is usually made between a pigment, which is insoluble in the vehicle (resulting in a suspension), and a dye, which either is itself a liquid or is soluble in its vehicle (resulting in a solution). The term biological pigment is used for all colored substances independent of their solubility. A colorant can be both a pigment and a dye depending on the vehicle it is used in. In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake pigment. From Wikipedia under the
GNU Free Documentation License How does the amount and type of different pigments in eyeshadow affect the way it looks on the skin? Q. I need to do a math project involving pigments and how the different types, and the amount have an affect on the way eyeshadow would look on the skin. I really need some help! Asked by Jenna Bear - Tue Mar 11 23:35:01 2008 - - 2 Answers - 0 Comments A. The more pigments there are in a product the more difference it makes in the appearance. I use MAC pigment and its loose powder, especially since its stage make up (MAC) there tends to be more different hues and tones in the pigment to make it look thicker and stand out more on the skin. While compared to a regular pressed eyeshadow at any store, they don't contain as many pigments, some girls have to apply up to 7 coats just to see a color difference. So yes the amount of pigments does effect the way it looks on the skin. And wow weird how its a math project...but I hope I helped!
