Science
Mechanism of Action
This ester functions by creating a hydrophobic film on the skin's stratum corneum. This physical barrier significantly reduces moisture evaporation, thereby locking in essential hydration. The sustained moisture retention leads to a visibly plumped appearance, improved skin texture, and a reduction in surface roughness.

Stability
For optimal performance in eye care formulations, a pH level close to 7 is recommended. To maintain product aesthetics and prevent graininess, reheating and thorough blending during manufacturing can be beneficial. In formulations intended for hot climates, the incorporation of waxes may be necessary to prevent liquification.
Safety
Safety Profile
The CIR Expert Panel has deemed shea-derived ingredients, including the parent Butyrospermum Parkii (Shea) Butter, as 'safe as used' when formulated to be non-sensitizing. While adverse reactions are uncommon, patch testing is prudent. No specific SCCS status was identified.
