Seepje is the most natural way to do your laundry. An organic laundry detergent, no harmful chemicals, just pure nature. The Seepje shells are actually shells of the Sapindus Mukorossi fruit, which grows on trees in Nepal and in other parts of the Himalayan area. These shells have a high concentration of foaming saponin, a natural soap which is released when they get in touch with water. In Southeast Asia the shells have been used for decades as a laundry detergent as it makes clothes perfectly clean. Isn't it beautiful what nature is giving us? That's exactly what we thought! The Seepje products are 100% natural, skin-friendly, softening, protecting and easy to use.
