I thought liquid soap didn't need preservative and made no plans to add any to mine. Do you mean you add 5% based on the weight of the soap after you have diluted it? Should I be worried about my soap paste as well?
That is a great idea, Susie. Hopefully I will remember it--I want to try making a paste for cleaning with. I temporarily put the extra paste into small canning jars and I don't want to give up fridge space for this.I separate my (no preservatives) paste into smallish containers, about 4-8 oz each. I prevent adding any bad stuff to the paste that way. I use one tub for everything-stain remover, kitchens, bathrooms, etc til it is gone. Then I grab a new tub next cleaning day. I started with larger containers, but soon decided that I did not want to use the paste in the kitchen after I had cleaned the bathroom. Those little Glad plastic containers(4 oz) make dandy soap paste holders. I can then wash the container, and re-use it next batch.
