A method for detaching, removing or otherwise disrupting bacteria or biofilm by applying with pressure an antimicrobial wash. The antimicrobial wash contains a biguanide compound or mixtures thereof.

Antimicrobial polymer coating formulations are prepared that protect biological surfaces by treating, reducing, ameliorating, preventing or inhibiting pathogenic microorganism ingress to a human or animal host, reducing the potential for infection, particularly by necrotizing fasciitis originating microorganisms, through use of a polymer coating barrier containing antimicrobial agents that facilitates sustained release of biocidal agents active against such opportunistic microorganisms. Such formulations are effective for inhibiting microbial ingress pertaining to soft tissue and skin tears, abrasions, punctures and surgical wounds, and can be used as in water environments and as a skin protectant sunscreen and insect repellent.

This invention relates to an oxidative hair cream composition that contains at least one oxidative hair cream ingredient and at least one polymeric colorant.
