Hi, the formula can be mixed but Pro Polymer may be too little because it contains multiple electrolyte ingredients which may cause the formula to liquefy. may have to adjust the proportion of Pro Polymer the formula can be mixed without heat. recommended preservative Mild Preserved Eco 1% ka

Thank you very much, I would like to ask more information about using HEPES (hydroxyethyl piperazineethanesulfonic acid) is a Buffer. If added to cosmetics, it will make the formula have a pH range of 5.0-6.5, right? yes And what percentage of the formula must be at least to act as a buffer, or do I need to adjust the pH again? Thank you in advance.

Hello, adjusting pH can't answer how many % must be used, must be adjusted and actually measured.
