I usually use chelator everywhere (except obvious formulas such as cationic system, W/O … ).
First of all, I have it on hand (plenty of it and such a small amount is used), it’s cheap and it helps preservative and antioxidant. -
We have had success with Euxyl K701 (Phenoxyethanol (and) Benzoic Acid (and) Dehydroacetic Acid (and) Ethylhexylglycerin) which is similar. We use a chelator (GLDA) and keep the pH at around 5.5.

Caprylhydroxamic acid is not that good as a chelator in preservative context.

Don;t see much benefit with DHA when you’ve Benzoate, esp. in a surfactant context.
