Polydextrose

What is Polydextrose?

Polydextrose is a branched-chain polysaccharide synthesized from dextrose, a simple sugar derived from corn starch, through a polymerization process involving heat and acid catalysis. This creates a water-soluble, non-digestible carbohydrate with a low molecular weight. In skincare formulations, it serves primarily in moisturizers, lotions, gels, and cleansers within the humectant and bulking agent categories. As a humectant, it binds water molecules from the environment and deeper skin layers, promoting retention in the upper skin barrier for a hydrated feel. Functioning as a bulking agent, it adds viscosity and volume to products, improving stability, spreadability, and overall sensory attributes without adding oiliness or residue. Its hygroscopic properties make it ideal for aqueous systems, helping maintain formulation integrity across varying humidity levels while contributing to a lightweight, non-sticky finish.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Bulking agent
Increases mass/volume to build structure and improve handling, commonly used to adjust feel, spread, and cost-in-use without acting as a primary active.
Humectant
Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.

Benefits

Enhances skin hydration by attracting and retaining moisture on the surface.

Improves product texture for better spreadability and a smoother feel during application.

Increases formulation volume to optimize consistency without heaviness.

Who It's For

A quick guide for who this ingredient may suit (and who should be cautious).

Who May Benefit Who Should Avoid
Individuals with dry or dehydrated skin seeking gentle moisture support.
Those with rare sensitivities to corn-derived polysaccharides.
Users preferring lightweight, water-based skincare products.
Individuals preferring oil-free or anhydrous formulations.
People looking for texture enhancers in daily moisturizers or cleansers.
People avoiding synthetic polymers in their routines.

Safety Notes

  • Considered safe for cosmetic use with low hazard ratings from assessments.
  • Non-comedogenic, unlikely to contribute to pore clogging.
