Human color vision not only prompts them to appreciate the colors that appear in life, but also drives them to use a range of technologies to produce colors in the environment they build. Color has become one of the main factors appealing to consumers, especially in food, pharmaceuticals, cosmetics and care products. A colorant is a substance that is used to impart color to matter. It provides the color that consumers want and thus enables them to obtain satisfactory products in a variety of areas. Colorants have structures which contain a delocalized system with conjugated double bonds called chromophore and color aids called auxochromes. The chromophore exhibits resonance of electrons, which enables it to absorb light in the visible region of the electromagnetic spectrum. Auxochromes are responsible for shifting the wavelength and controlling the solubility of the colorant. A suitable colorant must have good performance on the substrate, economically viable and, minimum environmental and health effects in its life cycle. As a company dedicated to creating value for our customers, Alfa Chemistry is committed to providing safe and high-quality colorants for food, pharmaceutical, cosmetic, personal and home care products worldwide.
