I am working on a green laundry detergent recipe to sell to consumers. I want to do my part in saving this planet. I understand that soap nuts with a few other natural ingredients works great for what I am trying to do but the liquid version of it has to be used within 3 to 4 days. Do you have any recipes or suggestions on what to use for preservatives to make it have a longer shelf life?

You can also use GSE (Grape Seed Extract). It's sold in most Health Food Stores. It's a 100% Natural cleaner & antibacterial made from Grapefruit Seeds. Using the name-brand of "Nutribiotic". It cost about $12 or so for a small bottle, but it should last you quire some time cause you only need a little!

* Lots of Soap makers use GSE to preserve their homemade soap.
Grapefruit seed extract (GSE) is an antioxidant - this is great to use in oils to prevent them from becoming rancid, but it is not a preservative. To date there is not an all natural preservative. A preservative isn't necessary in a dry laundry detergent, but if you are adding water to a bar soap, it may grow bacteria and/or mold - If you make a laundry detergent using a liquid soap paste that was made with oils and potassium hydroxide, your detergent should be safe based upon the ph of the end product.
