POTASSIUM ETHYLPARABEN

Description

Potassium ethylparaben is a preservative commonly used in cosmetic and pharmaceutical products to prevent microbial growth and extend shelf life. This synthetic compound belongs to the paraben family and is the potassium salt of ethylparaben. It is particularly effective against molds and yeasts, making it valuable in water-based formulations.

With a molecular formula of C9H9KO3, potassium ethylparaben appears as a white, crystalline powder that is highly soluble in water. Its efficacy is maintained across a wide pH range, typically from 4 to 8, allowing for versatility in various product formulations. The ingredient works by disrupting microbial cell membranes and inhibiting cellular processes essential for bacterial growth.

While effective at low concentrations, typically 0.01% to 0.3%, potassium ethylparaben is often used in combination with other preservatives for broad-spectrum protection. Its use is regulated by cosmetic and food safety authorities worldwide, with established safe concentration limits. However, like other parabens, it has faced scrutiny due to concerns about potential endocrine disruption, leading some manufacturers to seek alternative preservatives. Nonetheless, it remains an important tool in maintaining product safety and stability when used within regulatory guidelines.
