CORN STARCH/MALTODEXTRIN CROSSPOLYMER.

Valuable / FILM FORMING

CORN STARCH/MALTODEXTRIN CROSSPOLYMER is a versatile plant-derived ingredient designed to enhance skin hydration and refine product textures. It forms a protective, non-occlusive film on the skin's surface, while its humectant properties actively bind moisture to minimize transdermal water loss. Furthermore, it expertly manages excess oil, contributing to a balanced complexion.

Science

Mechanism of Action

This crosspolymer primarily functions by forming a lightweight, breathable film on the skin, contributing to a smoother feel and enhanced ingredient delivery. Derived from corn starch and maltodextrin, its components act synergistically: Maltodextrin serves as an effective humectant, drawing and retaining moisture to boost skin hydration and mitigate moisture evaporation. It also acts as a sophisticated texture enhancer and thickener, optimizing the sensory experience of formulations by imparting a smooth, creamy consistency. Beyond skin benefits, it stabilizes emulsions by preventing oil and water phase separation, and selectively absorbs excess sebum, making it beneficial for oily or combination skin. Additionally, it possesses the capacity to encapsulate and protect sensitive active ingredients from degradation, thereby improving their stability, penetration, and overall efficacy within the formula, and may support a healthy skin microbiota.

Stability

CORN STARCH/MALTODEXTRIN CROSSPOLYMER, particularly its maltodextrin component, acts as a stabilizing agent within formulations. It effectively prevents the separation of water and oil phases in emulsions and offers protection to unstable active ingredients, such as enzymes, shielding them from environmental stressors like UV light and enhancing their longevity and performance in cosmetic products.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has determined that polysaccharide gums, including maltodextrin and modified corn starch, are safe under current conditions of use. Maltodextrin itself is affirmed as Generally Recognized As Safe (GRAS) by the FDA for direct food use, further supporting its safety profile. Modified corn starch is widely regarded as non-toxic, hypoallergenic, and non-comedogenic. No specific SCCS opinion for CORN STARCH/MALTODEXTRIN CROSSPOLYMER was identified in the available data.
