Chemical Structure
Basic Info
Propylparaben is a commonly used synthetic preservative with a chemical formula of C ₁₀ H ₁₂ O3 and a molecular weight of 180.20 g/mol. It belongs to the class of parabens.
Propylparaben appears as white crystals or powders at room temperature, with a slight distinctive odor. Its melting point is 96-98 ° C and boiling point is approximately 295 ° C. Its physical properties include slight solubility in water (about 0.25 g/L at 25 ° C), but easy solubility in organic solvents such as ethanol, propylene glycol, and ether.
The chemical structure of Propylparaben contains a phenolic hydroxyl group and a propyl ester group, giving it weak acidity and good antibacterial activity. It has high stability and is not easily decomposed under acidic to neutral conditions, but it may undergo hydrolysis in strong alkaline or high-temperature environments, producing p-hydroxybenzoic acid and propanol.
Propylparaben’s chemical properties make it widely used in the cosmetics, pharmaceutical, and food industries as a preservative, effectively inhibiting the growth of bacteria, mold, and yeast. Its antibacterial mechanism mainly involves damaging the cell membrane of microorganisms and interfering with their metabolic processes.
Propylparaben has the best anti-corrosion effect in the pH range of 4-8 and is often used in combination with other parabens to enhance its antibacterial spectrum.
Although the safety of Propylparaben is widely recognized at low concentrations, high doses may cause skin allergies or endocrine disruption controversies, and therefore its use is restricted by some national regulations. High performance liquid chromatography (HPLC) is a commonly used method for determining the content of Propylparaben in analytical testing.
