Butylparaben is a high-efficiency, broad-spectrum preservative belonging to the paraben family. Featuring distinctive solvent compatibility and stable chemical properties, the ingredient exhibits excellent solubility in common organic solvents including ethanol, acetone and diethyl ether. It presents slight solubility in heated water and is nearly insoluble in cold water. Under ambient temperature and atmospheric pressure, the compound maintains stable chemical status. It performs outstanding stability in neutral and weakly acidic mediums, while its preservative efficacy will be compromised and structural stability declines when exposed to strong alkaline environments.
Key Advantages
Compared with methylparaben and ethylparaben, butylparaben delivers superior bacteriostatic performance against common microorganisms covering bacteria, yeast and mold.
It boasts wide environmental adaptability in conventional production formulas and retains stable anti-corrosion activity in most neutral and weakly acidic product systems.
With high purification degree and stable quality, this preservative meets mainstream global industry testing standards, supporting safe formulation in food, cosmetic and daily chemical products within specified dosage ranges.
