Seeking suggestions for preservatives system for facial wash / top to toe w
Hi, I am formulating for personal use a simple no tears face wash/top to toe. So far the below formulation works for me (no preservatives yet). I am considering adding fragrance oil and citric acid. Do I need to add sles? Feel free to suggest a better formulation.
The current formulation is
Sorbitol - 40%
Propylene glycol - 20%
Cocamidopropyl Betaine (30%) 14%
Water - 26%
What would be the best preservative system for this type of formulation? Is it better to make the water higher amount and less sorbitol?
