You can read more about preservatives here.
My opinion is the most effective preservation systems use parabens and formaldehyde donors. The ones you listed aren’t nearly as effective. -
Thanks. You got a really nice article.
So do you think

I’ve used 0.5% potassium sorbate at pH 5.5 in shampoo for years with no problem. Also sodium benzoate. Effective. In creams I use a combination of methyl and propyl parabens, and in gels I use Spectrastat.

Thank you. Good to know 0.5% Potassium Sorbate is not too much. I’m afraid of preservative overdose and bad products at the same time.

I’ve used Gluconolacctone (and) Sodium Benzoate on numerous occasions and have had no issues with it at 1.0% to 1.5%. A trick is that you do need to incorporate it into the water phase with no other ingredients under high shear and then heat to 70C. Otherwise, it has a tendency to partially re-crystallize if you incorporate it without heating. You can beef it up with the addition of 0.35% Potassium Sorbate. -
