Hypochlorous acid
The working ingredient — the molecule your own white blood cells produce. Small and uncharged, which is why it behaves nothing like the alcohols and detergents doing the work in most other hand products.

Turn most children's hand products over and the ingredient list runs to fifteen lines. This one runs to three — and two of them are water and salt.
The working ingredient — the molecule your own white blood cells produce. Small and uncharged, which is why it behaves nothing like the alcohols and detergents doing the work in most other hand products.
The activeThe carrier, and the reason the mist dries without tack. Deionised first — minerals in ordinary tap water would destabilise the HOCl within days.
The carrierTable salt. It's the electrolyte the hypochlorous acid is generated from, and what the solution gradually returns to as it ages.
The source
No, and the reason is pH. Below roughly pH 7.5 the solution is mostly hypochlorous acid — small, uncharged, gentle enough to leave on skin. Push the pH into the alkaline range and it converts to hypochlorite ion, which carries a negative charge. Household bleach sits at pH 11–13, which is why it's almost entirely hypochlorite, and why it burns.

Same family of chemistry. Different dominant molecule, different pH, roughly 350 times more dilute.
Almost everyone under-sprays for the first week. Coverage is what matters — the mist has to actually land on skin to do anything, so aim for visibly damp rather than lightly misted.
Close enough to land on the hand, far enough that the spray fans out properly rather than arriving as one wet dot in the middle of the palm. Too close is the most common reason coverage looks patchy.
Palm, then back of hand. For a toddler that's roughly four pumps in total; for a baby's hands, two is usually plenty. Don't skip between the fingers and under the nails — that's where most of it actually hides.
This is the only part people skip, and it's the part that does the work. Rubbing hands together helps it spread; wiping it straight off doesn't. Fifteen seconds of distraction — a song, a countdown, anything.
It dries clear with nothing left behind. If you're in a hurry, pat with a cloth once the fifteen seconds are up. No water needed at any point, which is the entire reason it works in a car park.

The ones that come up once the bottle is in the house, rather than before.
Yes, within reason. Stored properly with the cap on, plan on twelve months from opening. If it's been open two years in a sunny kitchen, replace it rather than trust it.
It's alcohol-free and designed to be left on the skin, which is why parents move to it from gel in the first place. It isn't made to be drunk, though — keep the bottle out of reach, and for babies and young toddlers spray onto your own hands and transfer.
It shouldn't — the absence of alcohol is the reason it gets used on grazed knees at all. Expect nothing beyond the sensation of something cool and wet.
For external use. Keep out of reach of children. Avoid contact with eyes. Not a substitute for washing with soap and running water where a sink is available. If skin irritation occurs, stop use. If your child has a diagnosed skin condition or is under active treatment, speak to your GP, health visitor or dermatologist first.
