Science
Mechanism of Action
This compound operates primarily by adjusting pH, generating a basic solution when hydrated. Furthermore, it acts as a surfactant and emulsifier, capable of breaking down dried oil films and aiding in the solubilization of various substances on the skin's surface.

The Formula
Formulation
Stability
Morpholine is highly miscible with both water and many organic solvents, and exhibits thermal stability up to 288°C in steam systems. A critical formulation concern is its potential to react with nitrosating agents, leading to the formation of N-nitrosomorpholine.
Conflicts
- Nitrate or other nitrosating agents
Safety
Safety Profile
The CIR Expert Panel found insufficient data to support Morpholine's safety in cosmetic applications. A primary concern is the formation of N-nitrosomorpholine in the presence of nitrosating agents, a compound identified as mutagenic and carcinogenic. Unneutralized Morpholine has been observed to be irritating. While a 1% concentration was reported as neither an irritant nor sensitizer in a specific formulation, the overall safety profile remains a concern. The FDA permits Morpholine in some direct and indirect food additive applications.

Verdict
Despite its functional versatility as a pH adjustor and emulsifier, the significant safety concerns regarding the potential formation of carcinogenic N-nitrosomorpholine, coupled with insufficient CIR data, advise against its use in precision skincare formulations.
