BUFFERING
pH StabilizerMaintains stable pH levels in products
SCIENTIFIC ANALYSIS
// Evidence: Buffering systems resist pH changes through weak acid-conjugate base pairs (citric acid/sodium citrate, lactic acid/sodium lactate, phosphate salts) that operate within specific pH ranges based on their pKa values. The mechanism follows the Henderson-Hasselbalch equation, with buffer components neutralizing added H⁺ or OH⁻ ions. Proper buffering prevents pH drift and maintains efficacy.
