Agricultural byproducts were valorized by micronizing discarded Prinsepia utilis Royle seed residue into an eco-friendly Pickering stabilizer. The resulting particles showed interfacial emulsifying behavior, stronger performance with non-polar oils, and endogenous polyphenol-derived antioxidant activity, establishing a green route to bioactive colloid systems for cosmetic formulation.
