sodium carbonate and sodium sulphate in laundry bar soap

[simon onwuli]

Thank you.
My quest is to make best laundry bar soap possible with PKO. My soap is not for bathing but washing clothes. I know sodium carbonate and sulphate could be added in liquid soap and detergent. So when some soapers around added them in their laundry bar soap, I was wondering it outcome in my recipe.

I came here to learn.
Thank you.

How litres of pko I should use in making soap
