About
A diol-linked di-salicylate ester used as a UV-B absorber and emollient. Novel salicylate variant, limited public data.
Hexanediol disalicylate is a di-ester formed from 1,6-hexanediol and two salicylic-acid molecules. Chemically it is a close relative of established salicylate UV filters (e.g. ethylhexyl salicylate / Octisalate listed in EU Annex VI at up to 5%) but with a longer diol spacer giving higher molecular weight and lower volatility. In cosmetics it is used as a UV-B absorber and emollient. Because this specific ester is not explicitly listed on EU Annex VI as a UV filter, its regulatory status depends on how the formulation is claimed; if used for aesthetic/emollient purposes it falls under general cosmetic rules. No CIR or SCCS review for this exact INCI. Scored conservatively pending more public data.
Function
Skin benefits
- Salicylate-based UV absorber with diol spacer
- Lower volatility than simple salicylates
- Can serve as UV-B booster
Known concerns
- Salicylate UV filters have modest sun protection power
- Limited public independent safety data for this specific ester
- Not broadly approved on Annex VI as a standalone
