Sodium isobutylparaben

Sodium isobutylparaben (CAS 84930-15-4) is the sodium salt form of isobutylparaben, offering improved water solubility compared to its parent ester.

Where is Sodium isobutylparaben used?

• Cosmetics: antimicrobial preservative in rinse-off and leave-on formulations, controlling microbial growth at low concentrations
• Personal care: lotions, shampoos and cleansers
• Pharmaceuticals: topical creams and ointments
• It protects formulations against bacterial and fungal contamination to extend shelf life.
• Its salt form integrates readily into aqueous systems for water-based personal care products.
• It is evaluated in multi-preservative systems with paraben blends for synergistic antimicrobial coverage.

Good to know: Buyers should confirm compliance documentation, including CoA and safety dossiers, given ongoing regulatory scrutiny of paraben-class preservatives in key markets.
