POTASSIUM BUTYLPARABEN

Description

Potassium butylparaben is a synthetic preservative commonly used in cosmetic and skincare formulations. This ingredient belongs to the paraben family and functions as an antimicrobial agent, effectively inhibiting the growth of bacteria and fungi in products. Its primary role is to extend the shelf life of cosmetics and personal care items, ensuring they remain safe and stable for consumer use.

Chemically, potassium butylparaben is the potassium salt of butylparaben, with the molecular formula C11H13KO3. It is water-soluble and typically appears as a white, crystalline powder. The ingredient is effective at a wide pH range, making it versatile for various product types.

While parabens have faced scrutiny in recent years, potassium butylparaben is generally considered safe when used at regulated concentrations. The European Union allows a maximum concentration of 0.14% for butylparaben in leave-on products. It is less commonly used than other parabens due to regulatory restrictions and consumer preferences.

Formulators often choose potassium butylparaben for its broad-spectrum antimicrobial activity and compatibility with other ingredients. However, its use has declined as manufacturers increasingly seek alternative preservatives in response to market demands for paraben-free products.
