SODIUM PROPYLPARABEN
Description
Sodium propylparaben is a widely used preservative in cosmetic and pharmaceutical products. This sodium salt of propylparaben belongs to the paraben family of compounds and is derived from para-hydroxybenzoic acid. It functions primarily to inhibit the growth of bacteria and fungi, thereby extending the shelf life of various formulations.
The ingredient is particularly effective against gram-positive bacteria and some molds. Its antimicrobial activity is most potent in slightly acidic environments, making it suitable for a range of skincare and personal care products. Sodium propylparaben is water-soluble, allowing for easy incorporation into aqueous-based formulations.
In cosmetics, it is typically used at concentrations between 0.01% and 0.3%. The ingredient has a low risk of skin irritation and sensitization when used at these levels. However, like other parabens, it has faced scrutiny due to concerns about potential endocrine disruption, though regulatory bodies generally consider it safe at current usage levels.
Sodium propylparaben's stability across a wide pH range and compatibility with many other ingredients make it a versatile choice for formulators seeking effective preservation in their products.
