We use a purified form of potassium carbonate that has absorbed CO₂ directly from the atmosphere using a non-toxic, solvent-free process. The potassium carbonate is then integrated into our soap formulation. More info 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.

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.

mynus uses organic plant oils, natural colorants, essential oils and a CO₂‑based potassium carbonate in its lye system instead of relying only on conventional ingredients, and internal calculations suggest a potentially lower footprint, but these estimates (around 10 % lower than an average natural soap and 300x lower than a solid synthetic detergent bar) are preliminary and still need to be refined and independently validated.

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.

Yes, of course, as soon as your order is dispatched.
