CETETHYL MORPHOLINIUM ETHOSULFATE.

Insufficient Data CAS 78-21-7 / ANTIMICROBIAL, ANTISTATIC, HAIR CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A specialized cationic quaternary ammonium salt primarily utilized for its advanced odor-neutralization and antistatic capabilities. It serves as a molecular complexing agent that effectively sequesters malodorous compounds without interfering with traditional fragrance profiles.

Summary

Odor Neutralizer Antistatic Agent Hair Conditioning Agent Antimicrobial Surfactant

Science

Mechanism of Action

This ingredient functions via ionic attraction; its positive molecular charge neutralizes the negative static charge found on hair and skin surfaces. For odor control, it chemically complexes with volatile organic acids and sulfur-based molecules, lowering their vapor pressure to prevent them from being detected by olfactory receptors.

Since efficacy for odor neutralization begins at 0.25%, inclusions below this threshold are likely for label claims rather than functional performance. At Moumoujus, we look for a minimum of 0.25% to ensure active malodor complexing.

Our Assessment

Verdict

Insufficient Data

A highly effective odor neutralizer and antistatic agent that requires careful formulation due to its cationic nature and lack of comprehensive long-term safety data.
