Technical Datasheet | Supplied by DSM
Phenylbenzimidazole Sulfonic Acid. PARSOL® HS by DSM is a water-soluble UV-B filter for dry-touch high SPF formulations. It is recommended to prepare an aqueous pre-mix then neutralize with a suitable base such as NaOH, KOH, Tris, AMP, Tromethamine or Triethanolamine. Compatible with most cosmetic ingredients, and should be formulated at a pH >7 to prevent crystallization. It has an excellent photostability and safety profile. Since it leaves a dry touch on the skin, PARSOL® HS is recommended for sunscreens such as gels or clear sprays and light feel day care products.
