Science
Mechanism of Action
This ingredient functions as a physical abrasive that manually dislodges dead skin cells (corneocytes) and surface biofilms through controlled friction. Unlike inert exfoliants, it retains a high concentration of lauric and myristic fatty acids and Vitamin E (tocopherols), which help maintain the stratum corneum's lipid barrier and provide localized emolliency during the mechanical scrubbing process.

Clinical Evidence
High confidence1.5%
Key findings
- 01 Citróleo Group technical data confirms efficacy for gentle physical exfoliation and emolliency at 0.1% to 1.5%.
- 02 AWS Bio-derived and Sustainable Formulas Guide (2019) validates safety and stability at high-intensity concentrations up to 15%.
Transparency
Dusting Analysis
To achieve a functional mechanical effect, a minimum concentration of 0.1% is required. Levels below this are typically insufficient for noticeable exfoliation and are often used for marketing claims rather than performance.
The Formula
Formulation
Stability
The powder is a highly stable solid resistant to oxidation. Formulators should incorporate it at temperatures below 60°C to protect the integrity of the natural vitamins and fatty acids within the seed matrix.
Synergies
- Rheology modifiers (Xanthan Gum, Carbomer) to ensure uniform suspension
- Surfactant systems for clarifying cleansers
Conflicts
- Strong oxidizing agents
- Low-viscosity aqueous bases (prone to sedimentation without suspending agents)
