Science
Mechanism of Action
This ingredient functions as a bio-available skin conditioner and cosmetic biocide. Upon application, skin-resident enzymes called amidases metabolize the compound into its constituent caprylic acid and essential amino acids. This process replenishes the Natural Moisturizing Factor (NMF) and provides a targeted antimicrobial effect that inhibits odor-causing bacteria without disrupting the delicate epidermal microbiome.
Research
Clinical Evidence
High confidence0.65%
Key findings
- 01 VCRP data reviewed by the CIR panel indicates a typical maximum use level of 0.65% in leave-on skincare for optimal efficacy and safety.
- 02 Comparative clinical testing on related amino acid alkyl amides at concentrations up to 7.38% demonstrated a complete lack of dermal irritation or sensitization in human subjects.
Transparency
Dusting Analysis
Because this ingredient is effective at concentrations as low as 0.65% in leave-on products, it is rarely 'dusted.' However, inclusion levels below 0.1% may fail to provide the functional antimicrobial and conditioning benefits described.
The Formula
Formulation
Stability
Demonstrates excellent structural stability within the physiological pH range of 4.5 to 8.5. It is chemically resistant to hydrolysis during shelf storage but remains biologically active upon skin contact.

Safety
Safety Profile
The CIR Expert Panel considers it safe in current practices. While higher-concentration surfactants in this chemical class can be irritants, this specific amino acid derivative is utilized at low, non-irritating levels.
