CI 75470

Last update on Jun 18, 2024
CI 75470, commonly known as Carmine, is a cosmetic colorant that imparts a bright red pigment to products like lipsticks. This natural ingredient is safe for use even on sensitive parts such as the eye area. However, Carmine is really expensive and falls under the animal cruelty list since it is derived by crushing the female cochineal beetles. Although effective, it cannot be used in animal-friendly or vegan formulations. In its raw form, CI 75470 appears as a dark pink to red powder. It provides a stable and intense red color to a variety of products such as lipsticks, blushes, and eyeshadows.

What is CI 75470 used for?

CI 75470 is widely used in cosmetics for its vibrant red color. It is a popular choice for lipsticks, eyeshadows, blushes, and other makeup products due to its intense and long-lasting color payoff. Carmine provides a rich hue that enhances the visual appeal of cosmetics, offering a natural and stable pigment. However, its presence in formulations is regulated, and alternatives like synthetic dyes or plant-based pigments are sought for vegan and allergy-friendly cosmetic options.

Origin

CI 75470 is produced by extracting carminic acid from female cochineal insects (Dactylopius coccus). The insects are harvested from cactus plants, dried, and crushed to release the carminic acid. This acid is then purified and precipitated with aluminum or calcium salts to form the pigment. The resulting pigment, carmine, is then processed into a fine powder or liquid form for use as a colorant in cosmetics.

Safety Profile

CI 75470 is considered safe for use in cosmetics by regulatory agencies such as the FDA and EU Cosmetics Directive when used within approved concentrations. However, it can cause allergic reactions in individuals sensitive to insect-derived products. Carmine is generally non-toxic when applied topically, but ingestion or inhalation of large quantities could potentially lead to adverse effects.
