CI 75300, also known as Curcumin, is a natural yellow pigment derived from turmeric (Curcuma longa). Widely used in cosmetics and personal care products for its vibrant yellow-orange hue, providing coloration in items such as soaps, lotions, creams, shampoos, and bath products. It offers good stability and dispersibility in formulations, with natural appeal for clean beauty trends. Primarily for external use with minimal skin absorption; not recommended for mucous membranes or areas of high absorption due to potential staining and sensitivity. Approved for cosmetic use in many regions, including the EU and US, but subject to purity standards and concentration limits (e.g., max 3% in rinse-off products).
