CAPRYL HYDROXYETHYL IMIDAZOLINE.

Valuable CAS 37478-68-5 / ANTISTATIC, HAIR CONDITIONING

A high-performance amphoteric surfactant designed to bridge the gap between effective cleansing and skin barrier preservation. It excels in creating transparent, stable formulations that leave a sophisticated, conditioning finish on both skin and hair surfaces.

antistatic skin conditioning cleansing surfactant deposition aid

Science

This molecule operates through electrostatic attraction; as a cationic-leaning agent, it binds to the negatively charged proteins on the skin's surface. This creates a microscopic, breathable film that reduces friction, neutralizes static, and facilitates the selective deposition of beneficial lipids to enhance moisture retention.

Key findings

  1. 01 Demonstrated 95% light transmittance in microemulsion systems at 0.5%, proving its efficacy in creating stable, crystal-clear conditioning formulas.
  2. 02 Shown to significantly improve the texture of damaged biological surfaces by enhancing oil deposition at concentrations between 0.1% and 1.5%.

Because this ingredient is effective at very low concentrations (0.1%) for surface conditioning, it is rarely 'dusted' in the traditional sense; however, levels below 0.1% may not provide the tactile benefits advertised.
