What It Does
This is a carefully balanced blend of three iron oxide pigments (yellow CI 77492, red CI 77491, and black CI 77499) pre-dispersed in caprylic/capric triglyceride to create a versatile beige shade. The specific combination ratio determines the exact beige undertone, making it particularly valuable for color-matching diverse skin tones in foundations, BB creams, and tinted sunscreens. The pre-dispersion in this medium-chain triglyceride carrier significantly improves ease of incorporation, reduces formulation time, and ensures uniform color distribution compared to using dry powder pigments, while the iron oxides themselves provide inherent broad-spectrum UV protection including blue light attenuation.

Ingredient Compatibility
Known Interactions
Iron from iron oxide pigments can catalyze oxidation of Ascorbic Acid via Fenton reaction. Not a concern at typical pigment levels in tinted products, but avoid high concentrations of both.
