The present invention solves the problem that skin or coat treatment products which use catechin extract in a “cat-ionic” or “an-ionic” base have tended to be unstable. The problem addressed is the precipitation and color change (darkening) in just a few hours/days where products would not be commercially viable due to extremely short shelf life. The Non-Ionic Surfactant Solubilized High Catechin Content Emulsion invention achieves an efficacious level of catechins (in ranges up to and over 2% by weight) as a proper emulsification method for the high catechin content in a skin, scalp, or coat treatment that does not separate or darken and has a much longer shelf-life.
