I'm was suggested to use Sodium Benzoate as the preservative in the liquid soaps.
However, Wikipedia says Sodium Benzoate is effective upto pH 4.5 only. When I asked the chemist who suggested it, He said when molds grow they form a slightly acidic envirnment and the Sodium benzoate will become effective in it, effectively killing the mold.
Anyone tried using sodium benzoate as preservative in their soaps, I saw it in a commercially sold SLAS based handwash.
I would like to use it especially because it is a food grade preservative and easy to handle.
