Alcohol-based hand rub solutions

Ethanol, isopropanol and the water base

Hand-rub solutions may contain ethanol, isopropanol or a combination of alcohols according to the formula. Water and supporting ingredients form part of the final mixture. WHO reference formulations illustrate the inclusion of glycerol as a humectant, a different role from that of the alcohol. Percentages are read with their units, such as a volume-based expression. Complete composition and documented claims explain the product beyond its alcohol name alone. Supporting ingredients and their functions also distinguish an evaluated preparation from another liquid with a similar appearance.

Fluid solutions for hand rubbing

Liquids flow and spread differently from gels. Dispensing depends on the cap, pump or intended dispenser; fluidity and flow rate are separate characteristics. Alcohol-based rubbing concerns visibly clean hands within the context described by INRS. Quantity and contact directions belong to the product. Texture alone therefore cannot establish activity, which is understood through the formula and evaluated use conditions. A fluid solution's handling description should remain connected with its intended hand use rather than transferred to a surface-cleaning preparation.

Bottles, refills and dispensing points

Small personal bottles, counter pumps and wall-mounted cartridges provide different handling arrangements. Refills may be dedicated to a precise connection system. Stability, opening and closure complete the container description. Alcohol-based preparations also have storage instructions associated with their nature, including ignition sources. In professional settings, hand rubs differ from water-rinsed washing soaps and surface disinfectants, each retaining its own purpose and directions. Available volume and any supplied pump then add practical details alongside the formulation and stated application method rather than defining them.
