    Might be related to micro contamination. If as it appears, benzoate is your only preservative, you’re clearly underpreserved.

      Alright thank you for the fast reply 🙏 so I need to increase the measurement of the benzoate or I need to add another preservative to it. And is there any way I can fix the soap?

        Can’t fix a micro problem, if that’s what it is. sorry, don’t have knowledge to address what it might be or a fix if just chemical.

    That’s a liquid dish soap, right? Put a sample in the fridge. If after few days that turbidity turns into a precipitate that settled at the bottom, then your sulfonate might me salting out. For that, you need to add some sodium xylene or cumene sulfonate. It’d also be adviceable to check before if there was any significant pH drift from when it was manufactured.
