C12-15 PARETH-10 PHOSPHATE.

Valuable CAS 68071-35-2 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A biomimetic phosphate ester surfactant that mimics skin's natural lipid structure to create stable oil-in-water emulsions. Its phospholipidic backbone allows it to integrate seamlessly into the skin barrier while delivering gentle emulsification without the harshness typically associated with conventional surfactants.

Summary

Emulsifying Surfactant Cleansing Barrier enhancement

Science

Mechanism of Action

Functions as an anionic emulsifier that reduces interfacial tension between oil and water phases while integrating into the stratum corneum's lipid bilayer. The phosphate group structure mirrors natural skin phospholipids, enabling enhanced barrier reinforcement and improved moisture retention with a characteristic silky, non-greasy finish.

Stability

Maintains stability in neutral to mildly alkaline conditions but susceptible to hydrolysis below pH 3.0. Enhanced water solubility achieved through neutralization with alkanolamines or alkali hydroxides.

Synergies

  • Alkanolamines for pH adjustment
  • Alkali hydroxides for solubility enhancement

Conflicts

  • Hard water minerals (calcium/magnesium precipitation)
  • Strongly acidic formulations
  • Cationic surfactants (complex formation)
