There are several solutions for hand sanitizers. Disinfectant hand washes (liquid soaps) are available on the market, which can only be used in washrooms or places suitable for hand washing. These products must be applied to wet hands and then rinsed off with clean water after the exposure time has elapsed. The other option is hand sanitizers that can be used without rinsing, this preparation simply needs to be applied to the surface of the hand and then allowed to dry. Because of the alcohol, this happens relatively quickly in a few seconds. In the case of the latter product, we can distinguish between two types, one is a gel-based hand sanitizer, and the other is a liquid-based hand sanitizer. The gel products are available in very small packages that can be placed in a bag or pocket, while the liquid products are available in larger 500 ml, 1 liter, and 5 liter bottles. Both types can be used with automatic and manual feeders, but you must pay attention to choosing the right type. The gel products can be used with a holder suitable for dispensing liquid soap, while the liquid can be used with a spray dispenser. Another important aspect when choosing a dispenser is the tightness of the device. They are alcoholic preparations, so they evaporate. The gel is therefore more prone to drying out.
