Description

Dodecyl 4-Hydroxybenzoate is a synthetic organic compound belonging to the paraben ester family, valued for its antimicrobial and preservative properties. This compound is essential for formulators seeking to extend the shelf life and microbiological stability of a wide range of products. It is primarily needed by manufacturers in the personal care, cosmetics, pharmaceutical, and industrial sectors where effective, broad-spectrum preservation is a critical requirement.

Application

• As a preservative in cosmetic and personal care formulations such as creams, lotions, and shampoos.
• Used in topical pharmaceutical preparations (ointments, gels) to prevent microbial growth.
• Employed as a stabilizing agent in industrial products like adhesives, paints, and lubricants.
• Potential use as a food-contact material preservative in packaging applications.
• Intermediate in the synthesis of other specialty chemicals and longer-chain paraben esters.
• Component in research and development for studying preservative efficacy and release systems.
