Expert Verdict

Generally regarded as safe; non-toxic, non-irritating, non-sensitizing at cosmetic use levels. Modified cellulose polymer of synthetic/plant origin; excellent film-forming and thickening capabilities; water-soluble; thermogelling behavior (gels upon heating, liquefies upon cooling - unusual reverse thermal gelation)
