The 13.5 oz (400 ml) bottle is the everyday refill for the kitchen sink, the bathroom and the office washroom — a true concentrate that's only about 20% water, so it cleans harder and lasts longer than the watered-down pump soap sitting next to it on the shelf.
Why concentrated beats watered-down
Most supermarket hand soap is 85–92% water. You pay full price to ship and store a bottle that's mostly... water. Power One flips that ratio: roughly four-fifths of every pump is active cleansers, walnut-shell scrubbers and skin conditioners. A little goes a long way, which is exactly why a small bottle outlasts a same-size bottle of the cheap stuff. The full breakdown is in our guide to concentrated soap vs regular soap.
How walnut-shell soap actually cleans
Power One carries nearly 20% real walnut-shell scrubbers — fine, biodegradable grit that lifts grease, ink, paint and ground-in grime instead of just covering it with fragrance. There are no petroleum solvents, and six skin emollients leave hands soft instead of cracked and tight. See walnut shell vs pumice for why the softer scrubber cleans hard without tearing up your skin.
It fits the dispenser you already own
The 400 ml bottle refills any foam or liquid dispenser, wall-mounted or countertop. Pour, cap, done — no trip to the warehouse store. Washing a lot of hands? Step up to the 3.55 L bulk refill (about 710 washes for pennies each) or pair this with our lifetime-guaranteed wall dispenser.
Who the 13.5 oz is for
- Homes that want a premium, non-drying hand soap at the kitchen or bath sink
- Offices topping off a single washroom dispenser
- Anyone who wants to try the concentrate before buying in bulk

Frequently asked questions
Will the 13.5 oz bottle dry out my hands?
No. Power One has no petroleum solvents and six skin emollients, so it lifts grease and grime without the cracking and tightness you get from typical industrial or shop soaps.
Does it work in a foam dispenser?
Yes — it works in both foam and liquid dispensers, wall-mounted or countertop. Just refill whatever you already own.
How is it different from regular pump soap?
Regular pump soap is mostly water, often 85–92%. Power One is a true concentrate at roughly 20% water, so more of every pump is actual cleanser and it lasts noticeably longer.
Is it good for the environment?
It's USDA Certified Bio-Based at 70%+ content and super-concentrated, so there's less water to ship and less plastic per wash — especially when you refill instead of rebuy.
