Hand sanitizer is a liquid or gel generally used to decrease infectious agents on the hands. PS129 is a disinfectant with ethanol and hydrogen peroxide as the main effective ingredients, which is usually used to sterilize skin and surgical hands. How does sanitizer work? Just one squirt of sanitizer will help to keep your hands clean. Users do not need to wash or rinse their hands with water. We enhance the formula with nourishing skin-conditioning agents in a skin-friendly formulation that's mild on hands. In that case, this hand sanitizer not only avoids bacterial remaining on hands but also protects hand skin from irritation.
