Science
Mechanism of Action
This ingredient operates mainly through mechanical action; as an abrasive, its granular structure helps to physically dislodge surface impurities via a grinding and polishing effect. Furthermore, its ability to swell allows it to act as a bulking agent, which contributes to reducing the overall density of cosmetic products. It is crucial to distinguish that while the broader Phaseolus Radiatus Seed *Extract* has been associated with various active skin benefits, such as antioxidant properties, moisturization, soothing, and collagen stimulation, these specific biological mechanisms are not attributed to the isolated starch component.

Dusting Analysis
Research does not provide specific data regarding dusting thresholds or red-flag percentages for PHASEOLUS RADIATUS SEED STARCH. While it acts as a bulking agent to reduce product density, this does not inherently classify it as a commonly dusted ingredient in the context of user application.
The Formula
Formulation
Stability
Mung bean starch demonstrates good cold-water solubility, ranging from 78.5% to 94.2% at room temperature, and exhibits an oil-adsorption capacity between 43.1% and 62.1%. Its water solubility can be enhanced in alkaline solutions. pH levels are known to influence starch characteristics, with increasing extraction pH from 7 to 9 potentially enhancing crystallinity, while higher pH (10-11) may decrease it due to ionization.
Safety
Safety Profile
No specific GHS classification or hazard statements, nor determinations of dermal, oral, or inhalation toxicity, were found for PHASEOLUS RADIATUS SEED STARCH. Neither the Cosmetic Ingredient Review (CIR) nor the Scientific Committee on Consumer Safety (SCCS) has specifically assessed this isolated ingredient for cosmetic use. While 'food starch-modified' is permitted by the FDA for direct addition to food, and corn-derived ingredients are generally considered safe by CIR, specific cosmetic assessments for this starch are absent. It is important to note that the broader Phaseolus Radiatus Seed *Extract* is generally deemed safe but, like many natural components, may elicit allergic reactions (redness or itching) in individuals with sensitive skin.

Verdict
PHASEOLUS RADIATUS SEED STARCH is an optional ingredient valued for its physical abrasive and bulking properties in formulations, though direct active skincare benefits for the isolated starch are currently unsubstantiated by specific clinical data.
