Abstract
High quality non-aerosol foam sanitizers include a liquid mixture that includes an alcohol, water and a surfactant mixed with and entrapping air to form a plurality of foam bubbles. Wherein more than about 50 percent of the foam bubbles have a size of between about 50 μm and about 250 μm.
Claims18
A non-aerosol foam sanitizer comprising:
- a liquid mixture that includes c1-c8 alcohol in an amount of between 40% and 85% by weight, water and a surfactant mixed with and entrapping ambient air sourced from the atmosphere to form a plurality of foam bubbles;
- wherein more than about 50 percent of the foam bubbles have a diameter of between about 50 μm and about 250 μm;
- wherein the foam bubbles are generated using a liquid pump portion for pumping the liquid mixture that includes c1-c8 alcohol, water and a surfactant and two or more air pump portions for pumping atmospheric air into a mixing chamber for mixing the foamable the liquid mixture with the atmospheric air to form the bubbles having the above size as the bubbles are dispensed;
- and
- wherein the liquid pump portion and the two or more air pump portions are activated sequentially.

A non-aerosol foam sanitizer comprising:
- a liquid mixture that includes at least about 40% of a c1-c8 alcohol, water and a surfactant mixed with and entrapping ambient air sourced from the atmosphere to form a plurality of foam bubbles;
- wherein when the liquid mixture is passed through an non-aerosol foam pump, the average diameter of the foam bubbles are less than about 190 μm;
- wherein the non-aerosol foam pump comprises a liquid pump portion for pumping the liquid mixture that includes c1-c8 alcohol, water and a surfactant and two or more air pump portions for pumping atmospheric air into a mixing chamber for mixing the foamable the liquid mixture with the atmospheric air to form the bubbles having the above size as the bubbles are dispensed;
- and
- wherein the liquid pump portion and the two or more air pump portions are activated sequentially.
