Description:
Butylparaben is a fine, colorless, odorless, crystalline solid at room temperature. The molecular formula of butylparaben undergoes hydrolysis to its corresponding carboxylic acid in basic solutions. The antimicrobial activity of parabens increases with increasing alkyl chain length (methylparaben<ethylparaben<propylparaben<butylparaben<heptylparaben) and this antimicrobial activity is retained across the pH range of 4 to 8.[8] Antimicrobial activity is usually enhanced by combining butylparaben with other biocides such as formaldehyde releasers, Isothiazolinones, or Phenoxyethanol.[9] It has been shown that butylparaben has the ability to cross body barriers, and enter the body through the lungs, GI tract, and skin epithelium
