Amine reagents and processes for artificial melanin nanoparticles for hair dyes

This invention describes a method to dye hair using artificial melanin. It works by applying a solution of melanin precursors, an oxidizing agent, and specific amine compounds directly to the hair. These amine compounds create the necessary alkaline conditions for the melanin to form, but are designed to be gentler on the hair and scalp than conventional alkaline agents. The claims narrow the invention to amine compounds having a particular chemical structure.

Why it matters: The claims for the specific amine compounds are incomplete, suggesting the precise chemical structures were not fully defined at filing. The challenge remains to identify and validate the exact compounds that deliver the promised tolerability and efficacy.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateSpecific chemical formulations and synthesis
