The main active ingredient is Benzalkonium Chloride being at a very low level of 0.13% which will not cause any irritation. It can be an aggressive anti-bacterial agent at higher concentrations, this active is commonly used in skincare products.

The key to Quintessence is the Organosilane patented water stabiliser which is providing the anti-bacterial residual action on the skin, it is attaching to the carbohydrates of skin that polyhydroxylated, so it doesn’t penetrate the hardy skin cells hence still allowing the skin to breathhe nor will it get into blood streams like alcohol. Once dried it will not impede moisturisers from attaching to the skin, but those may not be necessary as Quintessence contains a moisturising agent.
