Libraphos P4 Ester is a clear amber liquid composed of phenol with 4EO phosphate ester. This product serves as an acidic version of Libraphos L66 and exhibits anionic properties, making it compatible with both other anionic and nonionic surfactants. Libraphos P4 Ester is versatile and suitable for use in both acidic and alkaline systems, even in high-temperature applications. Its primary role is as a hydrotrope for highly built systems and it comes highly recommended for the solubilization of low-foam surfactants within such formulations.
