“CIR Expert Panel says: safe as used in cosmetics.”
Dextrin is a starch-derived polysaccharide with a long history of safe use as a food additive (FDA GRAS). The CIR Expert Panel assessed dextrin as part of the Polysaccharide Gums group review (2015), finding it safe as used in cosmetic formulations. Human repeat insult patch testing at 42.6919% concentration in a rinse-off product showed no clinically significant skin irritation or evidence of allergic contact dermatitis. No ingredient-specific peer-reviewed studies on cosmetic skin safety for plain dextrin were identified in PubMed.
