p style="margin: 0px; text-align: justify;">Hand care products, including plain (non-antimicrobial) soap and antiseptic products, can become contaminated or support the growth of microorganisms. Liquid products must be stored in closed containers and dispensed from either disposable containers or containers that are washed and dried thoroughly before refilling. Soap should not be added to a partially empty dispenser, because this practice of &quot;topping off&quot; might lead to bacterial contamination of soap and negate the beneficial effect of hand cleaning and disinfection.</p
