Application
Key Benefits:
(1)Sunsafe-ES is a highly effective UVB absorber with a UV absorbance (E 1%/1cm) of min. 920 at around 302nm which forms water soluble salts with the addition of a base
(2)Sunsafe-ES is practically odorless, has an excellent stability and is compatible with other ingredients and packaging
(3)It has an excellent photostability and safety profile
(4)A tremendous SPF increase can be achieved by combining Sunsafe-ES with oil-soluble UV absorbers as Sunsafe-OMC, Sunsafe-OCR, Sunsafe-OS, Sunsafe-HMS or Sunsafe-MBC. Therefore sunscreen formulations can be formulated using low concentrations of UV filters
(5)Suitable for water-based transparent sunscreen products such as gels or clear sprays
(6)Water-resistant sunscreens can be formulated
(7)Approved world-wide. Concentration maximum varies according to local legislation
(8)Sunsafe-ES is a safe and effective UVB absorber. Safety and efficacy studies are available on request
It is an odorless, off-white powder which becomes water soluble upon neutralization. It is recommended to prepare an aqueous pre-mix then neutralize with a suitable base such as NaOH, KOH, Tris, AMP, Tromethamine or Triethanolamine. It is compatible with most cosmetic ingredients, and should be formulated at a pH >7 to prevent crystallization. It has an excellent photostability and safety profile. It is well known in the industry that Sunsafe-ES can lead to a tremendous SPF boost, especially in combination with Polysilicone-15 but also with all other available sun filters combinations. Sunsafe-ES can be used for water-based transparent sunscreen products such as gels or clear sprays.
