TrizChlor 4 Spray is a topical solution built around 4% chlorhexidine gluconate paired with tris-EDTA, a combination formulated to work on skin surfaces that respond to chlorhexidine. The liquid comes in a pump spray bottle and is meant to be shaken well before each use. It can be applied directly to a dry coat and left to air dry, or used after shampooing by first removing excess moisture from the coat and then spraying it onto the skin and haircoat. The formula includes a light fragrance and is designed to be non-irritating on compromised or sensitive skin. It is intended for topical use in dogs, cats and horses as part of a routine skin and coat care regimen, and repeated or ongoing use should follow guidance from a veterinarian.
