A closer look
What the research shows
Safety assessment
The report assesses native cyclodextrin toxicology within the polysaccharide group and distinguishes chemically modified cyclodextrins.
What this does not tell us
Safety assessment combines native-cyclodextrin toxicology with group read-across; it is not a trial of cyclodextrin skin benefits. Chemically modified cyclodextrins and oral studies have distinct identity or exposure conditions.
