Science & Benefits

A branched-chain hydrocarbon propellant. It is highly volatile and evaporates almost instantly upon leaving the container. Because it does not remain on the skin, it has zero interaction with the pores or the skin barrier. It is 100% non-comedogenic and is a standard, safe choice for delivering foaming acne treatments or lightweight aerosol sunscreens.
