Science
Mechanism of Action
This modified potato starch functions as a humectant by attracting and retaining moisture, thereby enhancing skin hydration. The oxidation process introduces reactive carboxyl and carbonyl groups into the starch structure, which significantly improves its water solubility and increases its chemical reactivity for effective skin conditioning.

Stability
This ingredient demonstrates excellent water solubility due to its oxidized nature. While oxidized potato starch films show good stability in acidic aqueous media, their integrity may be compromised in alkaline conditions. The recommended optimal pH range for similar hydroxypropyl potato starch derivatives is precisely between 4.5 and 8.0, suggesting this range for optimal stability and performance.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated HYDROXYPROPYLTRIMONIUM OXIDIZED POTATO STARCH. However, related modified starches, such as Starch Phosphates, are generally recognized as safe for cosmetic use. Notably, 'Oxidized Hydroxypropyl Starch' (without the trimonium modification) is approved as a food additive by the FDA under 21 CFR 172.892 and 175.105, implying a favorable safety profile for such starch modifications. 'Hydroxypropyl Potato Starch' is also defined by USP-NF with a hydroxypropyl content between 2.0% and 7.0%.
