Probably none. Glyceryl caprylate is a weak one and prob useless vs Gram neg’s, the bugs you’d target with formaldehyde. If you want that component, sure think a formaldehyde releaser would be preferable.

Prob will be effective - and shampoos in the 1940’s-60 often used formaldehyde. But it’ll scare today’s folks, and the odort maybe tough to cover.
There are regulatory demands/consttraints on its use - labeling, limit etc. - and may bring some bad press.Practical - wouldn’t go over 1000 ppm formaldehyde, prob less - see what works.

Formaldehyde labeling would be required for formalin and in many countries and EU for formaldehyde releaser.
