SODIUM BUTYLPARABEN

Description

Sodium butylparaben is a widely used preservative in cosmetic and personal care products. This sodium salt of butylparaben belongs to the paraben family of compounds and is known for its antimicrobial properties. It effectively inhibits the growth of bacteria and fungi, extending the shelf life of various skincare formulations.

The ingredient is typically used in concentrations ranging from 0.01% to 0.4%, depending on the product type and desired preservation efficacy. Sodium butylparaben is water-soluble, making it particularly suitable for aqueous-based formulations. It demonstrates optimal effectiveness in slightly acidic to neutral pH environments.

While sodium butylparaben is considered safe for use in cosmetics by regulatory bodies, it has faced scrutiny due to concerns about potential endocrine disruption. However, current scientific consensus maintains that at approved concentrations, it poses minimal risk to human health.

Formulators often combine sodium butylparaben with other preservatives to create broad-spectrum antimicrobial protection. Its stability in various formulations and compatibility with other ingredients make it a versatile choice for many skincare products, including creams, lotions, and cleansers. When used appropriately, sodium butylparaben contributes to product safety and longevity without compromising texture or efficacy.
