Science
Mechanism of Action
The powder consists of finely ground particles that utilize physical friction to dislodge accumulated corneocytes from the stratum corneum. Beyond surface resurfacing, the whole-seed matrix releases lipophilic components including oleic and linoleic acids, which help maintain the lipid barrier during the exfoliation process.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Technical evaluations demonstrate effective removal of dead keratinocytes at concentrations between 0.5% and 5.0% without inducing chemical irritation.
- 02 Related research on Bertholletia excelsa derivatives indicates potential for collagen stimulation and antioxidant protection via polyphenol content at a 1.0% threshold.
Transparency
Dusting Analysis
Because this ingredient serves a physical purpose, concentrations below 0.5% in rinse-off products are typically insufficient to provide perceptible tactile exfoliation and may be used for marketing claims rather than functional efficacy.
The Formula
Formulation
Stability
The powder is insoluble and requires a high-yield stress rheology modifier, such as xanthan gum or carbomer, to remain suspended and prevent sedimentation.
Synergies
- Humectants
- Emollient oils
- Tocopherol
Conflicts
- Low-viscosity liquids
- Highly acidic environments (pH < 4.0)
Safety
Safety Profile
Considered safe for both wash-off and leave-on applications. Usage typically peaks at 1% for facial care and up to 10% for robust body treatments.
