What is liquid Castile Soap?
This is a pure soap that is made from olive oil, water & lye (caustic soda). Depending on the type of lye you can make liquid or hard soap.
Can I use the Dishwashing Liquid recipe as hand wash?
Absolutely! You can also experiment by adding other skin cleansing ingredients like Vitamin E, Shea Butter & Glycerine. If you have a foaming hand pump just leave out the Xanthan gum, you don't need to thicken it.
What does Xanthan Gum do?
It has a few functions but the main one is to thicken liquid solutions naturally. You will find it as a thickening agent in shampoos, conditioners, detergents & a lot of cosmetics.
Yes, but you will need to be extremely patient as this can take some time. You are best off mixing the xanthan gum with vegetable glycerine before adding to your mixture. This acts like a ‘roux’ (a mix corn flour & butter) used to thicken a soup, the butter helps spread the flour more evenly through the soup so there are less lumps. The glycerine works the same way with the xanthan gum however lumps still can form. So, the next step is to whisk the solution fast to create a vortex & then slowly add your glycerine gum mix. Then you need to keep whisking & whisking until lumps are gone.
A cheap stick blender will do the job. You could also use an upright blender, thermomix or whatever you have that will whisk fast. You don't need to have a separate blender for this & cooking, after all your making dishwashing liquid :-)
Is this safe for septic tanks?
The ingredients are mild, safe & biodegradable which should not affect the bacteria in septic tanks like harsh chemicals can.
Should I use distilled water?
Only if you are going to make a large batch that won't be used right away or your tap water is very hard. Not only should it be free from any contaminates but it has less hard minerals that react with soap. For a small batch that will be used within 4-6 weeks normal tap/boiled water should be fine.

This awesome recipe is exactly the same for dish liquid as it is for hand wash. The only difference is you may want to add a few more fancy things to your hand wash like Vitamin E, Aloe Vera or Jojoba Oil which your dishes would survive without.
