Expert Verdict
A standout ingredient for pH-flexible formulations, active from pH 3–8 with broad antimicrobial efficacy across nearly the entire cosmetic pH range. Functions as both a preservative booster and chelating agent by disrupting metal-dependent microbial metabolism, making it invaluable in hurdle systems where pH cannot be tightly controlled. One of the best options for clean, broad-pH preservative systems with very low sensitization potential.
