METHYL MORPHOLINE OXIDE.

Avoid CAS 7529-22-8 / CLEANSING, SURFACTANT - CLEANSING, SURFACTANT - FOAM BOOSTING

Methyl Morpholine Oxide (NMMO) is primarily recognized as a powerful solvent for cellulose in industrial applications and as a co-oxidant in organic synthesis. While sometimes cited for potential surfactant, foam boosting, and cleansing properties in cosmetic contexts, current research does not indicate a specific active mechanism for skin benefit.

Surfactant Foam Booster Cleansing Agent

Science

Mechanism of Action

Research has not identified a specific mechanism of action for Methyl Morpholine Oxide as an active skincare ingredient. Its principal function in industrial settings is to dissolve cellulose by disrupting its hydrogen bonds, and it serves as a co-oxidant and sacrificial catalyst in various chemical oxidation reactions.

Stability

N-Methylmorpholine N-oxide is soluble in polar solvents, notably water and ethanol, and is generally stable under normal conditions. However, in aqueous solutions, a water concentration of not less than 4% is crucial to prevent its decomposition. The compound itself is slightly alkaline, but analytical separation of NMMO and its degradation products requires a pH below 3.5.

Conflicts

  • Reducing agents (due to its oxidant properties)
  • Transition metals (undergoes oxidation)
  • Strong acids (may affect stability and lead to decomposition products)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Methyl Morpholine Oxide is classified as a hazardous substance, with warnings against inhalation and ingestion. It is recognized as an irritant to the eyes, respiratory system, and skin. An 81.5% concentration applied to rabbit skin caused moderate irritation, and severe irritation was observed in rabbit eyes. It also carries a risk of allergic reactions in sensitive individuals. There is no specific review by the CIR or SCCS for its use as a cosmetic ingredient, nor a direct FDA status for skincare product applications.

Our Assessment

Verdict

Avoid

Given its classification as a hazardous substance, documented high irritancy, and absence of identified active skincare benefits or regulatory review for cosmetic use, Methyl Morpholine Oxide is not recommended for topical skincare formulations.
