Science
Mechanism of Action
Caprylic Acid operates through membrane disruption; its lipophilic structure inserts into the lipid bilayers of microbial membranes, causing physical disintegration. Within the skin, it fills intercellular gaps to smooth texture and functions as an 'internal acidifier,' lowering the local pH to facilitate the deeper penetration of other fat-soluble active ingredients.
Research
Clinical Evidence
High confidence0.8%
Key findings
- 01 Eradicated stubborn fungal biofilms (Candida species) when paired with polygalacturonic acid by compromising cell membrane integrity.
- 02 Displayed direct bactericidal activity against plasma membranes, reaching minimum inhibitory concentrations at approximately 7.5 mM.
- 03 Confirmed as a non-sensitizer in human maximization tests, showing a 0% reaction rate among participants.
Transparency
Dusting Analysis
Because it doubles as a texture enhancer and a preservative booster, it is rarely 'dusted' at negligible levels; however, concentrations below 0.2% may lack sufficient antimicrobial punch for acne-prone skin.
The Formula
Formulation
Stability
Highly stable due to its saturated carbon chain. It naturally lowers formulation pH and may impart a faint, characteristic odor that requires sophisticated scent masking.
Synergies
- Polygalacturonic acid
- Lipophilic actives
- Natural preservatives
Conflicts
- Strong bases (causes saponification)
- Strong oxidizing agents
Safety
Safety Profile
Recognized as GRAS (Generally Recognized as Safe) by the FDA. The CIR expert panel deems it safe when the final product is formulated to be non-irritating.
