Dextrin

Description

Dextrin is a versatile carbohydrate polymer derived from starch through partial hydrolysis. This water-soluble compound consists of D-glucose units linked by α-(1,4) and α-(1,6) glycosidic bonds. In skincare formulations, dextrin serves multiple functions, primarily as a thickening agent, stabilizer, and film-forming ingredient.

The molecular structure of dextrin allows it to effectively bind water, contributing to improved product texture and stability. It forms a smooth, non-tacky film on the skin's surface, which can help to lock in moisture and create a temporary barrier against environmental stressors. This property makes dextrin particularly useful in moisturizers, serums, and other hydrating formulations.

Dextrin is generally well-tolerated by most skin types and is considered non-comedogenic. It can enhance the spreadability of products and improve their overall sensory experience. In some formulations, dextrin may also act as a delivery system for active ingredients, potentially increasing their efficacy.

While dextrin is primarily used for its functional properties, some research suggests it may have mild antioxidant effects, though further studies are needed to confirm these potential benefits in skincare applications.
