Benzylparaben

Benzylparaben (CAS 94-18-8), also known as Benzyl p-hydroxybenzoate, is a paraben-series preservative used in cosmetics, pharmaceuticals, and food-contact applications.

Where is Benzylparaben used?

• Cosmetics and personal care: broad-spectrum preservative in creams, lotions, and emulsions
• Oil-rich or anhydrous systems: effective where water-soluble preservatives underperform
• Pharmaceuticals: protects topical preparations, ointments, and some oral dosage forms
• Fragrance and flavor compositions: flavoring agent at controlled use levels
• It inhibits microbial growth in formulations where longer chain parabens are preferred.

Good to know: Longer chain parabens are valued for enhanced lipophilicity and oil-phase compatibility. Buyers sourcing for regulated pharmaceutical or personal care applications should confirm compendial compliance.
