Hydrolyzed Corn Starch Hydroxyethyl Ether

What is Hydrolyzed Corn Starch Hydroxyethyl Ether?

Hydrolyzed Corn Starch Hydroxyethyl Ether is a derivative of corn starch, a natural polysaccharide from corn kernels. The starch undergoes hydrolysis to reduce molecular weight, followed by hydroxyethylation—attaching hydroxyethyl groups via ethylene oxide reaction—yielding a clear, water-dispersible gel former resistant to salts and pH changes. Primarily used in skincare creams, lotions, serums, and hair products, it functions by swelling in water to create viscous networks that control flow properties, prevent ingredient separation in emulsions through interfacial film formation, and bind atmospheric moisture to maintain product and skin hydration. This modification enhances solubility and performance over native starch, enabling lightweight textures in water-based formulations without greasiness.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Enhances product stability by preventing separation and improving shelf life.

Boosts hydration by attracting and retaining water on the skin surface.

Creates smooth, spreadable textures for comfortable application.

Who It's For
