Washing your hands with hot, soapy water for 20 seconds is the best defense against pathogens, however there are times that is not possible. I keep the hand sanitizer nearby when I have accidentally or by necessity needed to touch my face. The hand sanitizer is 62% alcohol (a requirement) with 10% aloe vera gel concentrate and 15% essential oils (high concentration). This formulation is similar to the immune support blend but has augmented antiviral essential oils like eucalyptus, lemongrass, hyssop, geranium, ravensara, cinnamon, and tea tree. Aloe vera lessens the drying effect of the alcohol.
