  • FILL

    Put the mixing pebble in the bottle, and fill with warm water up to the indicated line

  • DROP

    Drop the entire refill into the bottle (incl. the sachet), then screw the pump on tightly


    Shake like a cocktail for 1 min, then leave overnight if you can, if not you can already use it after 15 min

  • PUMP

    Voilà! It can take up to 48 hours for your soap to fully mix, don't worry if it seems a little watery initially


My new favourite hand soap. Fun product that reminds you of your time in the science lab in school!


It works great and smells great! Will totally keep using it.


I am loving my hand wash! It showed up just before one of my flare ups and it was the only soap that was fragrance free for me to use. I have been taking it with me everywhere. Thank you for an amazing product, it has been my life saver.


Brilliant scent, feels great on my skin, and always enjoyable to use.


Just wanted to let you know how much we love our handwash! We’re getting compliments from all our guests and I’m just about to head to your website to see what else I can get for our household!


Un pas de plus dans la réduction de nos déchets. Très belle innovation. En plus : on adore la texture et l’odeur.



Blackmarket is about making soap, not waste. A refillable liquid handwash without single use plastic packaging founded by Martina Schwarz in 2020


Martina used to work for big companies like Unilever and P&G, developing packaging for their beauty brands. She realised that her work was contributing to more plastic waste. So Martina decided that she could do more to reduce unnecessary packaging waste.   

In 2020, Martina created Blackmarket. We at Blackmarket are fully dedicated to reducing waste, challenging how we deliver personal care and beauty products, by selling refills in a concentrated format.

We exist to reduce packaging waste from your personal care routine, by bringing you products you love, in an eco friendly concentrated format. All you do is add water.
