Heptyl p-hydroxybenzoate

Heptyl p-hydroxybenzoate is a chemical compound that belongs to the class of organic compounds known as parabens. Parabens are a type of esters that are derived from p-hydroxybenzoic acid. Heptyl p-hydroxybenzoate is characterized by a heptyl group attached to the carbon of the carboxyl group of p-hydroxybenzoic acid.

Chemical Structure

The chemical structure of heptyl p-hydroxybenzoate consists of a benzene ring substituted with a hydroxyl group (OH) at the para position and a carboxylate ester group where the esterifying alcohol is a heptyl group. The heptyl group is a seven-carbon alkyl chain.

Properties

Heptyl p-hydroxybenzoate is a solid at room temperature. It is slightly soluble in water but more soluble in organic solvents due to its long alkyl chain. It has a mild, characteristic odor.

Uses

Heptyl p-hydroxybenzoate is used as a preservative in various products, including cosmetics, pharmaceuticals, and food. It is effective against a broad spectrum of microorganisms, including bacteria, yeasts, and molds. It is also used as a flavoring agent in food and beverages.

Safety

The safety of heptyl p-hydroxybenzoate has been evaluated by various regulatory authorities. It is generally considered safe for use in cosmetics and food at the concentrations typically used. However, like other parabens, it has been subject to controversy due to potential health concerns, including potential endocrine disruption.
