CI 45370

Description

CI 45370, also known as D&C Orange No. 5 or Acid Orange 7, is a synthetic azo dye widely used in cosmetic and personal care products. This water-soluble colorant imparts a vibrant orange hue to various formulations, including skincare items, makeup, and hair dyes. Its molecular structure allows for excellent color stability across a range of pH levels, making it versatile for different product types.

In skincare applications, CI 45370 is primarily utilized for its aesthetic properties, enhancing the visual appeal of products without directly contributing to skin benefits. The concentration of this dye in formulations is typically low, adhering to regulatory limits set by cosmetic authorities worldwide. While generally considered safe for topical use, some individuals may experience sensitivity or allergic reactions, particularly those with a history of reactions to azo compounds.

It's important to note that CI 45370 is not approved for use in products applied near the eyes in some regions, including the United States. Formulators must consider regulatory restrictions and potential skin sensitivities when incorporating this ingredient. As with all colorants, patch testing is recommended for consumers with sensitive skin or a history of allergic reactions to cosmetic ingredients.
