Is the hand sanitizer weakly acidic or weakly alkaline?
Hand sanitizer is alkaline. Shower gel, hand sanitizer, and soap are all alkaline. Because the sweat secreted by the human body is acidic, coupled with the inorganic salt precipitated with the sweat, and the oil secreted by the skin surface, the dirt on the skin will be acidic, so cleaning products Will be made alkaline. The hand sanitizer is free of phosphorus, aluminum, alkali, sodium alkylbenzene sulfonate and other ingredients. It adopts the principle of gentle decontamination and is easily accepted by the skin. Hand sanitizers are alkaline and have a stimulating effect on children's skin. In addition, people who are prone to skin allergies should not use hand sanitizer to wash their hands.
Hand sanitizer, weak acid or weak base, which is better

Therefore, the weakly alkaline hand sanitizer is more suitable for hand cleaning and Care. But it should be noted that it is best to wipe dry with a paper towel after use.
