The colors should be like sanitary clean colors like red,blue light blue Green. It is a product to protect and eliminate virus .. so I imagine like a fighter not precisely a Warrior with helpmet but maybe a dr with face mask. Something institutional that can express protection- clean- safe -hygiene 

A use of a shield can be useful for this logo, I will attach many ideas so we can create a global idea. Maybe more human like than cartoon (no cartoon) or silouhette human like. Only one person(guardian) in image. Somehow include a cross ( like the health and hospitals use)

The shield design would be used as bullet points in the label. Like 
(Shield) kills 99.5% of virus and Bacteria
(Shield) with natural ingredients 
(Shield) etc..

The label is going to be made for a product to be sold to hotels, airlines, hospitals households.. most of the label would be ingrediants, safety information, and letters so it is important to be great because is the only and main attention catcher in the label.
