Science
Mechanism of Action
The extract operates through the formation of a high-molecular-weight polysaccharide matrix (heteroxylan) on the skin's surface. This breathable, thixotropic film functions as a moisture reservoir, effectively reducing trans-epidermal water loss (TEWL) while providing secondary antioxidant benefits via its endogenous phenolic compounds.

Key findings
- 01 Wang et al. (2018) identified the seed gum's significant water-holding capacity and film-forming structural characteristics.
- 02 Wang et al. (2019) demonstrated the extract's thixotropic behavior, providing a smooth, non-tacky skin feel through its high-molecular-weight branched polysaccharide structure.

Dusting Analysis
Because this ingredient is often used to achieve specific viscosity and sensory profiles, it is typically included at functional levels. However, concentrations below 0.1% are insufficient to establish the film-forming barrier required for measurable hydration.
The Formula
Formulation
Stability
Maintains peak stability in water-based systems. Formulators must monitor electrolyte levels, as high salt concentrations can destabilize the polysaccharide gum structure and decrease overall viscosity.
Synergies
- Glycerin
- Sodium Hyaluronate
- Panthenol
Conflicts
- High electrolyte concentrations
- Strong cationic surfactants
Safety
Safety Profile
Recognized for safety in Japanese Quasi-Drug standards. While raw seeds of the Rosaceae family contain amygdalin, the cosmetic-grade extract is processed to ensure non-toxicity and skin compatibility.
