Maltodextrin is a plant‑derived polysaccharide produced through the hydrolysis of starches (commonly corn, potato, or rice) into shorter glucose chains that retain high water solubility and hygroscopic properties. In skincare formulations, maltodextrin functions as a humectant, stabilizer, emulsifier, binding agent, and film‑former, contributing to enhanced texture, moisture management, and product integrity. Its ability to absorb and retain moisture at the stratum corneum‑environment interface supports hydration and helps maintain barrier function, while film‑forming characteristics create a subtle protective layer on the skin surface that can extend the sensory comfort and longevity of topical products. Additionally, maltodextrin’s interaction with other ingredients improves emulsification and reduces phase separation, which is especially useful in complex emulsions, serums, and hydrophilic formulations targeting dry or dehydrated skin profiles.

In haircare applications, maltodextrin’s structural properties make it valuable for texture enhancement, conditioning, and moisture retention. It can help to improve volume, thickness, and manageability in shampoos, conditioners, and styling products by providing a lightweight conditioning film that smooths cuticles without weighing hair down, while its absorbent characteristics assist in formulations designed to control excess sebum or impart a matte finish. Maltodextrin’s functional versatility also allows it to serve as a carrier for actives in hair serums and scalp treatments, facilitating product stability and uniform distribution of performance components across diverse hair types.
