Abstract
The invention provides compositions and methods for reversible covalent binding of benefit agents to keratinous substrates through the reaction of a dicarbonyl functional group on the surface of a benefit agent with reactive amines on keratinous surfaces. The deposits formed are durable and resistant to transfer, but are readily removed by contacting the deposit with an amine-containing solution.
