Mrs. Homegrown here:
I’m trying to take a temperature reading on soap nuts. Have you used them? Did you like them? How do you use them–as laundry detergent, shampoo, soap? Do you use whole nuts or make a liquid? How long have you been using them? Do you find a big difference between brands?
If you could shoot me a comment, I’d really appreciate it.
On a more advanced level, I’m curious about their interactions with soil and compost, so if you have any thoughts on that, I’d love to hear them. I’m curious as to how they’re harvested, and if their growing popularity is impacting their local ecosystems.
If you’ve never heard of soap nuts, let me know that, too! I’m wondering where they sit in the general public awareness.
Soap nuts are saponin-rich fruits, usually of a tree called Sapindus mukorossi (though all Sapindus make soaping fruits), which can be used for laundry and other cleaning purposes. They’re usually sold only lightly processed: seeded and dried. A handful of these dried fruits, which look somewhat like small dates, are put into a cloth sack and thrown in with the laundry. The fruits release saponins, natural surfactants, which clean the clothes. Supposedly. I hear mixed things. I’m experimenting with Maggie’s Soap Nuts
