About

Ethyl Dihydroxypropyl Paba is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Ethyl dihydroxypropyl PABA (CAS 58882-17-0) is an alkyl-modified PABA derivative where the amino group is dihydroxypropylated, reducing the photosensitization risk of the parent PABA. It has been used as a UV filter in some sunscreen formulations. While structurally improved compared to PABA itself, it retains some structural alerts from the aromatic amine moiety. It is not specifically listed in EU Annex II or III, placing it in a similar regulatory grey area as other PABA derivatives. Limited modern dermatological data exists on its sensitization potential, and it has been largely superseded by modern photostable UV filters such as avobenzone and bemotrizinol. The score reflects moderate concern relative to the most restricted ingredients in this batch.

Skin benefits

  • UV filter function (historically used in sunscreens)
  • May provide some UVB protection

Known concerns

  • Structural alerts from PABA heritage
  • Limited modern sensitization data
  • May be photosensitizing in some individuals
  • Largely replaced by safer modern UV filters
