There you are with greasy fingers after buffalo chicken wing night, and your a Foam Pump(KEXON) hand soap is coming up empty. A real drag. Advancements in soap technology, specifically foaming hand soaps, are making soap a more noticeable commodity, however.

Soap has evolved from its ubiquitous bar form to liquid and foam options. Liquid soap wasn’t marketed until the 1970s, and foaming soap has only recently become popular. Public restrooms and business restrooms around the world now rely almost exclusively on liquid soap options because of their relative cleanliness, sustainability, ease of use, and cost-effectiveness.

Truth be told, the Foam Pump hand soap is a form of liquid soap. It is derived from a diluted form of liquid soap that is infused with air to create a foamy lather as it leaves the dispenser. Specialized dispensers are required to use foaming hand soap properly. Some are designed for use without refilling, and others are refilled regularly.

Some soap is kept in a pressurized container, and some is mixed with air in the dispensing unit when the pump is activated.

A pump-style dispenser has two chambers. One chamber holds soap and one pumps air into the dispensing unit when the pump is depressed. Pressurized dispensers are usually automatic and activated by placing hands directly underneath them. When the pump operates, the pressurized soap is released from its container in a measured amount. These types of dispensers aren’t refilled by adding more soap, but are refilled with a sealed packet or cartridge of pressurized soap.
