AMMONIUM XYLENESULFONATE.

Valuable CAS 26447-10-9 / SURFACTANT - CLEANSING, SURFACTANT - HYDROTROPE, VISCOSITY CONTROLLING

A water-soluble hydrotrope that enhances product clarity and texture by improving the solubility of active ingredients in aqueous formulations. This functional ingredient works behind the scenes to prevent cloudiness and stabilize surfactant systems without significantly altering product viscosity.

Science

Functions as a hydrotrope by reducing the critical micelle concentration (CMC) of water, thereby increasing the solubility of poorly water-soluble organic compounds and enhancing the wetting properties of formulations

Key findings

  1. 01 OECD assessment confirms hydrotropes including ammonium xylenesulfonate show no skin sensitization potential and no genotoxic or carcinogenic effects through dermal exposure

Transparency

Not commonly dusted

Primarily used as a functional ingredient rather than for direct skin benefits, making dusting practices irrelevant
