I recently had the chance to try out Green Virgin Products Soap Nuts Liquid. This small bottle says it has 120 loads in it - which is great for per-ounce use and small amounts of packaging! The liquid is non-toxic, super concentrated, hypoallergenic, and chemical free. The soap comes from USDA Certified Organic Sapindus Mukorossi Soap Nuts. The pump top makes it easy to use - just two pumps worked fine for my laundry.
An added bonus - there's always a little bit of soap left in the bottom of any bottle, and this liquid makes a great cleaner when diluted, so it will be the perfect way to use up anything that's left. It ends up being cheaper - and better for you and the planet - than conventional liquid detergents, so it's a great option for everyone!
