Pro Formulator Notes
Use a calibrated pH meter for accurate adjustment.
Add pH adjusters gradually because even small additions can significantly alter the final pH of a low-buffer system.
For commercial production, conduct stability, compatibility and microbiological/preservative efficacy testing before assigning a shelf life.
An airless pump or suitable serum packaging can help minimise unnecessary exposure during use.
