Colour Index International
Colour Index International (CI) is a reference database jointly maintained bSDC Enterprisesand the American Association of Textile Chemists and Colorists. It currently contains over 27,000 individual products listed under 13,000 Colour Index Generic Names. It was first printed in 1924 but is now published solely on the Internet. The index serves as a common reference database of manufactured colour products and is used by manufacturers and consumers, such as artists and decorators. Colourants (both dyes and pigments) are listed using a dual classification which use the Colour Index Generic Name the prime identifier and Colour Index Constitution Numbers. These numbers are prefixed with C.I. for example, C.I. Acid Orange 7 or C.I. 15510. (This abbreviation is sometimes mistakenly thought to be CL, due to the font used to display it.) The generic name lists first the class of dye (acid dye, disperse dye, etc.), then its hue (e.g., orange), followed by a number assigned by the Col ...

Azo Dye
Azo dyes are organic compounds bearing the functional group R−N=N−R′, in which R and R′ are usually aryl and substituted aryl groups. They are a commercially important family of azo compounds, i.e. compounds containing the C−N=N−C linkage. Azo dyes are synthetic dyes and do not occur naturally. Most azo dyes contain only one azo group but there are some that contain two or three azo groups, called "diazo dyes" and "triazo dyes" respectively. Azo dyes comprise 60–70% of all dyes used in food and textile industries. Azo dyes are widely used to treat textiles, leather articles, and some foods. Chemically related derivatives of azo dyes include azo pigments, which are insoluble in water and other solvents. Classes Many kinds of azo dyes are known, and several classification systems exist. Some classes include disperse dyes, metal-complex dyes, reactive dyes, and substantive dyes. Also called direct dyes, substantive dyes are employed for cellulose-based textil ...

Food Colorant
Food coloring, color additive or colorant is any dye, pigment, or substance that imparts color when it is added to food or beverages. Colorants can be supplied as liquids, powders, gels, or pastes. Food coloring is commonly used in commercial products and in domestic cooking. Food colorants are also used in various non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Some colorings may be natural, such as with carotenoids and anthocyanins extracted from plants or cochineal from insects, or may be synthesized, such as tartrazine yellow. In the manufacturing of foods, beverages and cosmetics, the safety of colorants is under constant scientific review and certification by national regulatory agencies, such as the European Food Safety Authority (EFSA) and US Food and Drug Administration (FDA), and by international reviewers, such as the Joint FAO/WHO Expert Committee on Food Additives. Purpose of food coloring People associate ...

Naphthalenesulfonates
Naphthalenesulfonates are derivatives of sulfonic acid that contain a naphthalene functional unit. A subfamily of compounds are the aminonaphthalenesulfonic acids, which describes precursors to several azo dyes.
