POTASSIUM O-PHENYLPHENATE

Description

Potassium O-phenylphenate is a versatile synthetic compound widely used in skincare and cosmetic formulations. This ingredient functions primarily as a preservative, helping to extend the shelf life of products by inhibiting the growth of bacteria, yeasts, and molds. Its chemical structure consists of potassium salt of o-phenylphenol, granting it antimicrobial properties.

In skincare applications, potassium o-phenylphenate is typically incorporated at low concentrations, usually between 0.1% to 0.5%, depending on the formulation requirements. It demonstrates effectiveness across a broad pH range, making it suitable for various product types. This preservative is particularly valued for its stability in the presence of other ingredients and its ability to maintain efficacy in challenging formulations.

While potassium o-phenylphenate offers robust preservation, it's important to note that some individuals may experience sensitivity. As with any preservative, patch testing is recommended for those with sensitive skin. Regulatory bodies, including the FDA and EU Cosmetics Regulation, have established guidelines for its safe use in cosmetic products. Formulators often combine it with other preservatives to create a comprehensive preservation system, enhancing overall product protection against microbial contamination.
