The Dial Professional 1-Gallon Refill is a high-capacity option for homes that require a steady supply of antibacterial soap. It uses Benzalkonium Chloride as the active ingredient, which provides a consistent 99.9% kill rate against common household germs. This "Professional" version includes specific conditioners designed to help protect the skin during high-frequency use, making it a good choice for kitchen sinks where hands are washed often.
Build Quality & Usability
The frame of the industrial-style jug is sturdy and built for stacking in a storage area. Because the 1-gallon weight is about 8.6 lbs, using a smaller "working bottle" for daily refills can make it easier to handle and help prevent spills.
The liquid's viscosity is specifically tuned for foaming actuators. If you use this soap in a standard liquid pump, it will come out in a thin stream, which can be messy and wasteful. Specifications show the surfactant concentration remains stable for up to 24 months if kept in a cool, dry place. The large 38mm neck is designed for quick pouring into bulk dispensers, though a funnel can provide more precision for smaller openings.
For homes with very hard water, it is worth noting that mineral buildup can sometimes affect foaming nozzles. A periodic rinse of your dispenser's pump head with warm water will help maintain the 1:15 air-to-liquid ratio that this soap is designed for. The "Original" scent is the classic Dial fragrance that many find familiar and clean.
If you would like a different fragrance in a similar bulk size, the Sanit Lavender 1-Gallon Refill is a great alternative. For organizing these heavy jugs and other cleaning supplies, check out our rolling storage shelves.
