What Is CI 75300?
CI 75300 is a synthetic organic colorant approved for use in cosmetic products under the Cosmetic Regulation. It belongs to the class of certified colour additives and is used primarily to impart colour to formulations rather than to provide skincare benefits.
As a cosmetic colorant, CI 75300 serves a purely aesthetic function in product formulation, allowing manufacturers to create visually distinctive products. It does not interact with skin in a therapeutic capacity.
How It Works
CI 75300 is a synthetic dye that disperses throughout a cosmetic formulation to provide stable colour. It functions as a visual additive only and does not participate in skincare mechanisms or skin biochemistry.
Clinical Evidence & References
Limited published data exists specifically on CI 75300's safety profile in skincare applications. Research examining colourants in cosmetic products, including this ingredient, suggests that contact allergic reactions to approved cosmetic colorants are rare, though individual sensitivity varies.
The ingredient is approved for cosmetic use under stringent regulatory frameworks that set maximum permitted concentrations. However, comprehensive clinical safety data specific to skincare use remains sparse.

How to Use
CI 75300 is incorporated by manufacturers during formulation and does not require special application guidance from consumers. It is present in the finished product at regulated concentrations determined by the manufacturer.
