HOCl mist vs thermal water vs toner
Three kinds of face spray and bottle get mixed up. This page goes only by what each pack and ingredient list shows, so you can tell them apart without relying on the wording on the front. It does not rate any product, and we haven't tested any.
What each product type is
- HOCl face mist. A cosmetic sold in a pump or spray bottle, with HYPOCHLOROUS ACID in the ingredient list (the name the EU cosmetic-ingredient inventory, CosIng, uses). No propellant is listed on the examples below.
- Thermal-water spray. Spring water sold as a cosmetic, usually named after its source. On the example we checked, the ingredient list is the spring water itself plus nitrogen, the gas in the pressurised can.
- Toner. A word describing how a product is meant to be used, not a fixed recipe. Toners range from plain waters to lists that can include alcohol, acids, plant extracts or fragrance, so read the ingredient list.
Side by side
| Product type | What’s in it (from the label) | Typical packaging | What to check on the label |
|---|---|---|---|
| HOCl face mist | Example 1: Aqua, Sodium Chloride, Hypochlorous Acid (water, salt, hypochlorous acid). Example 2 lists hypochlorous acid alongside added plant oils (eucalyptus, rosemary, tea tree). | Pump or spray bottle. No propellant listed on either example. | The full ingredient list, the date or period-after-opening symbol, the size and the price per 100 ml. |
| Thermal-water spray | Example: spring water (Avène Aqua) and nitrogen. | Pressurised can (aerosol), 150 ml and 300 ml on the example. Nitrogen is the gas. | The ingredient list, the date or period-after-opening symbol, the size and the price per 100 ml, and the can’s own warnings. |
| Toner | Varies. It can include alcohol, acids, plant extracts or fragrance. One product sold as a toner lists only water, salt and hypochlorous acid. | Varies by product. | The full ingredient list, the date or period-after-opening symbol, the size and the price per 100 ml. |
Examples, all checked 19 October 2026:
- HOCl mist, example 1: “BRIOTECH Renew Toner Hypochlorous Acid Spray - Gesichts HOCl Spray, 100 ml” on amazon.de. Ingredients as listed there: “Aqua. Natriumchlorid. Hypochlorige Säure”. The shop files it under face toner (“Gesichtswasser”).
- HOCl mist, example 2: “medicube Hypochlorous Acid Daily Facial Spray”, 125 ml, on notino.ee.
- Thermal-water spray: “Eau Thermale Avène Thermal Spring Water Spray” on avene.co.uk, “Detailed composition”: “AVENE THERMAL SPRING WATER (AVENE AQUA). NITROGEN”.
We checked one thermal-water example only. We have not checked other brands, so this page says nothing about them.
The name on the front is not the formula
EU cosmetics labelling requires the pack to state the function of the product, unless that is clear from how it is presented (Regulation (EC) No 1223/2009, article 19(1)(f), checked 19 October 2026). Words such as “toner”, “mist” and “spray” are the brand’s own description of that function.
So a product with “Toner” in its name can be an HOCl mist, as example 1 above shows. And two products sold as HOCl mists can have very different ingredient lists, as examples 1 and 2 show. The ingredient list tells you what is in the bottle.
Reading the label
For the ingredient list, dates, symbols and price per 100 ml, use the label checklist. Before a first use, patch-test as on the routine page.
Who to ask
If a label is unclear, or you have a skin or health concern, ask a pharmacist. This site can't answer it for you.
