Propyl para-hydroxybenzoate

Propyl para-hydroxybenzoate is a synthetic compound belonging to the paraben family of chemicals. It is produced industrially through the esterification of p-hydroxybenzoic acid with propanol. Parabens are often used as preservatives in various consumer products.

This substance functions as a preservative, inhibiting the growth of bacteria and fungi. It is added to a range of food products to extend shelf life, commonly found in baked goods, jams, and sauces. Its effectiveness at low concentrations makes it a popular choice for manufacturers.

Propyl para-hydroxybenzoate is an authorised food additive in Great Britain, listed on the Register of Food Additive Authorisations. European food safety authorities, including EFSA, have evaluated parabens. While generally considered safe at permitted levels, some studies have explored potential endocrine-disrupting effects, though regulatory bodies have concluded there is no conclusive evidence of harm to human health at typical dietary intakes. Evidence is mixed regarding long-term effects, and research is ongoing.
