The United States Patent and Trademark Office (USPTO) has issued patent US12582595B2 to L'OREAL for an "Eye cosmetic priming system." This patent covers specific cosmetic compositions, described as multi-purpose oil-in-water emulsions containing a high HLB surfactant system and a high load of talc. These emulsions are intended for use as a base for eye cosmetics to improve eyeshadow wear and facilitate mascara removal.

This is a grant of intellectual property protection for a novel cosmetic formulation. While it does not impose new regulatory obligations on other manufacturers, it establishes exclusive rights for L'OREAL concerning this specific technology. Companies operating in the cosmetic sector, particularly those developing eye makeup products, should be aware of this patent to avoid potential infringement and to inform their own product development strategies.
