I’ve tried a lot of sustainable laundry detergents in my quest to find something that didn’t make me break out in hives! Not only does this get my laundry clean properly but I haven’t had a single dermatitis reaction and I’m on my second bar. I cut it into quarters and use a hinged 32oz Ball mason jar with a tablespoon measuring spoon so that when I do my laundry it’s all right there. If you buy it with the box it comes with a cute little label sticker to place on whatever container you choose to use. One bar lasted my partner and I about two months doing 4-8 large loads of laundry per week.
Certainly a staple for me no. It does require a bit of planning to make it since it takes 8 hours to fully dissolve but it hasn’t been an issue for me, I just fill my jar up and plunk the cube in overnight and in the morning I can do my laundry.
