Tổng quan
Propylparaben, also known as Propyl p-hydroxybenzoate, is a paraben ester preservative produced by the esterification of p-hydroxybenzoic acid with n-propanol. It is an important member of the paraben family and one of the most widely used preservatives in food, cosmetics, and pharmaceuticals. Propylparaben appears as white crystals or crystalline powder with a slight characteristic odor and a slightly bitter taste. Its molecular formula is C10H12O3, molecular weight is 180.20, CAS number is 94–13–3, EINECS number is 202–307–7, and FEMA number is 2951. It is chemically inert and easily compatible with various compounds, serving as an antimicrobial preservative and flavoring agent. Propylparaben exerts its preservative effect by disrupting microbial cell walls and membranes, inhibiting nutrient absorption and reproduction processes. It has broad-spectrum antimicrobial activity against molds, yeasts, and bacteria, with stronger activity than ethylparaben. Compared with traditional preservatives (such as sodium benzoate), it offers lower usage concentration, broad-spectrum activity, safety, economy, and long effective shelf life. Propylparaben has been used as a preservative in the food, cosmetic, and pharmaceutical industries for over 50 years and is recognized as GRAS by the US FDA.
Appearance: White crystals or crystalline powder, slight characteristic odor, slightly bitter taste.
Molecular Formula and Molecular Weight: C10H12O3, molecular weight 180.20.
