"mynus" is a combination of the word "my", as in my action against climate change, and "minus", which symbolizes the need for a colder climate. In a word, mynus is about making the world a cooler place.

To bind carbon directly from the atmosphere, we harness a natural property of potassium hydroxide. This mineral agent acts as a magnet for CO2, pulling it straight from the ambient air and bonding with it to create potassium carbonate salt. We then carefully incorporate this salt into our soap recipes. You can find more information here.

You would need 540,000 mynus soaps if you fly from Berlin and back. From Munich it is only 500,000 soaps. Pleas ask for our bulk order options.

1.3 grams of captured CO₂ per soap might sound small, but it’s equivalent to the emissions of about 6 Google searches. Scaling this approach across products and industries is where impact grows. Each bar is a tiny protest against business-as-usual.

If 1.3g per soap isn't fast enough for you: Through our partner Climeworks, you can remove CO₂ from the air on a larger scale – either as a one-time purchase or via subscription, starting at just €1 for 10 kg. Use our coupon code "mynus" to get a 10% discount on one-time offsets or the first three months of a subscription.

While our soaps are not strictly carbon negative (removing more carbon than emitting carbon), our soaps have a lower carbon footprint than other natural soaps, thanks to our carbon capturing method. Our internal calculations suggest a potentially 10% lower footprint than an average natural soap, and 50% lower than a standard commercial soap. These calculations are still preliminary and still need to be refined and independently validated.

No, the captured CO₂ in the soap is chemically transformed into a stable salt. It is no longer in its gas form and cannot be released back into the atmosphere under normal usage. Instead, it remains safely bound within the soap’s solid structure, even as the soap is used and rinsed away.

These white marks are a natural result of carbonation, a harmless visual trace of the CO₂-captured ingredient. They are not mold or residue and may vary from bar to bar.

Beside being chemists ourselves, every recipe is assessed and approved for safety by an external, EU/UK qualified cosmetic safety assessor, as required by the European Cosmetics Regulation 1223/2009.​

Not at all. It isn't even CO₂ anymore. In our
CO₂ capturing process it converts into potassium carbonate which contributes to the luxurious lather and foaminess of our soaps.
