What it is
Dextrin Isostearate is made by esterifying dextrin, a polysaccharide from starch, with isostearic acid. It is an oil-gelling agent that thickens and structures the oil phase of a formula, helping to suspend pigments and powders and to give a smooth, even application. It is commonly used in oil-based and pigmented products such as sunscreens, base creams, and color cosmetics.
Safety & warnings
Dextrin isostearate is generally well tolerated and is widely used to structure oil phases in cosmetics. It is not associated with notable irritation or sensitization concerns at typical use levels.
Origin & sourcing
Synthesized by combining dextrin, a starch-derived carbohydrate, with isostearic acid, a branched fatty acid.
