Both are wrong.
Where effective Phenoxyethanol is usually fine at 5000 ppm and the other two are pretty useless in any application. Pseudomonads have plenty of esterases. -
Don’t waste your money on either - supplier marketing hype. Efficacy would be phenoxyethanol.

Doubt it pharma - lauric might but the longer chain fatty acids do not and would more likely undergo beta oxidation as substrate for the pseudomonads.
