Science
Mechanism of Action
Amylopectin forms a non-occlusive film on the skin's surface, acting as a humectant to lock in moisture and smooth fine irregularities. This high molecular weight polymer primarily functions within the stratum corneum, enhancing the skin barrier without penetrating deeper.

Key findings
- 01 In vitro studies on HaCaT cells demonstrated barrier protection by upregulating AQP3, Filaggrin (FLG), and Caspase-14, while inhibiting KLK7 (ResearchGate, 2025).
- 02 Preliminary studies indicate improved sensory attributes like smoother texture and enhanced moisture retention (Journal of Cosmetic Science, 2018).
Transparency
Dusting Analysis
As a functional film-former and viscosity-increasing agent, amylopectin integrates well into formulations to provide desired texture and hydration benefits, making dusting uncommon.
The Formula
Formulation
Stability
Amylopectin remains stable within typical cosmetic pH ranges (4.5-7.0) and is broadly compatible with active ingredients without impacting texture. It swells and gels upon heating in water.
Synergies
- Wide range of active ingredients for general compatibility
Conflicts
- Strong electrolytes (may reduce viscosity)
- High concentrations of alcohol (can cause precipitation)
Safety
Safety Profile
Reviewed as safe by CIR in 2015 and classified as GRAS by the FDA for food use, with no specific concentration limits for cosmetics.
