Science
Mechanism of Action
Operates through physical adsorption of lipids and Pickering emulsion stabilization. Its uniquely small particle size—significantly finer than corn or potato starch—allows for high surface area coverage to manage oil without clogging pores. High amylopectin levels enable it to bind water effectively, while its film-forming properties reduce transepidermal water loss (TEWL) by creating a protective but permeable matrix.

Key findings
- 01 Significant enhancement in mechanical film integrity (59.98 MPa tensile strength) and moisture barrier properties at 2% concentration (Dubey et al., 2026).
- 02 Efficiency as a Pickering stabilizer for high-oil phase emulsions (up to 80%) demonstrated at 1-5% concentration due to sub-micron particle size (Rayner et al., 2012).
Transparency
Dusting Analysis
While often used as a bulking agent, its functional role as a Pickering emulsifier and barrier enhancer requires concentrations of at least 1-2%. Amounts significantly lower than this are likely utilized for marketing claims rather than structural formula benefits.
The Formula
Formulation
Stability
Maintains structural integrity across an expansive pH range. It is insoluble in cold water and requires temperatures between 51°C and 72°C for gelatinization. Pickering emulsions utilizing this starch remain stable in highly acidic environments (pH 1.2).
