Ultramarines (CI 77007) A bright blue mined mineral pigment.

Urea Urea can be naturally-derived (urine is Urea!) or synthesised (and there’s no way to tell from the label), from two raw materials: ammonia and carbon dioxide. In cosmetics, urea attracts and retains moisture in the skin; use of this ingredient in a product can reduce the need for other preservatives since it is anti-microbial. In high quantities (higher than you’d find in cosmetics), it can be irritating to eyes or skin, but in low doses, it is anti-inflammatory, antiseptic and deodorising.
