SODIUM ISOBUTYLPARABEN

Description

Sodium isobutylparaben is a preservative commonly used in cosmetic and personal care products to prevent microbial growth and extend shelf life. This synthetic compound is a sodium salt of isobutylparaben, belonging to the paraben family of preservatives. Its molecular structure allows it to effectively inhibit the growth of bacteria and fungi in various formulations.

With a high solubility in water, sodium isobutylparaben is easily incorporated into aqueous-based products. It demonstrates efficacy across a wide pH range, making it versatile for use in diverse skincare and cosmetic applications. This preservative is particularly effective against gram-positive bacteria and some molds.

Typically used at concentrations between 0.1% to 0.3%, sodium isobutylparaben provides robust antimicrobial protection while minimizing the risk of skin irritation. Its stability in the presence of other ingredients and compatibility with most formulation types contribute to its widespread use in the beauty industry.

While generally regarded as safe when used within recommended limits, some consumers prefer paraben-free products due to ongoing debates about potential long-term effects. Formulators often combine sodium isobutylparaben with other preservatives to create broad-spectrum antimicrobial systems in cosmetic products.
