Isobutylparaben
Isobutylparaben is a synthetic preservative belonging to the paraben family, used to prevent the growth of bacteria, yeast, and mold in cosmetic and personal care products. This helps to maintain product integrity and safety over time. Its use has decreased due to consumer concerns, though regulatory bodies generally consider it safe at low concentrations.
