Expert Verdict
Levulinic acid is a bio-renewable, naturally derived organic acid preservative obtained from cellulose and starch hydrolysis, qualifying for COSMOS certification and clean-label positioning. It disrupts microbial energy metabolism and membrane integrity at low pH (pKa ~4.6; effective pH 3.0โ5.0), rarely used as sole preservative but effective in combination systems with reduced component concentrations, improving safety and sensory profiles. Emerging ingredient in clean-beauty formulations as natural alternative to synthetic acid preservatives.
