Science
Mechanism of Action
It functions through dual-action biophysical pathways: physically, its hydrophobic structure improves formula glide and water resistance; biologically, it disrupts the lipid membranes of pathogenic bacteria and inhibits their amino acid uptake, effectively neutralizing targeted microbes without harming beneficial skin flora.

Key findings
- 01 Demonstrated selective bactericidal activity against P. acnes and S. aureus with minimal impact on S. epidermidis, particularly effective at pH 5.0 (Morikawa et al., 2018).
Transparency
Dusting Analysis
Because it is effective at very low concentrations (0.1%) for antimicrobial benefits, it is frequently used as a 'claim ingredient' at negligible levels. At Moumoujus, we look for levels reaching at least 0.1% to ensure biological efficacy.
The Formula
Formulation
Stability
Maintains high stability as a dry powder with a melting point of 180°C; however, it is prone to precipitation in aqueous environments and may revert to lauric acid in highly acidic conditions.
Synergies
- Acidic stabilizers
- Non-ionic surfactants
- Hydrophobic emollients
Conflicts
- Cationic surfactants
- Hard water
- Strong oxidizing agents
- Strong mineral acids
Safety
Safety Profile
Extensively assessed by the CIR Expert Panel in 2019; safe for leave-on use even at high concentrations, provided the specific formulation remains non-irritating.

Verdict
An excellent selective antimicrobial and texturizer, though its high comedogenicity rating requires careful consideration in leave-on acne treatments.
