A UVB filter.
LGB® 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.
Effective water-soluble UVB filter when neutralized properly. A small dosage would improve SPF when used with other UV filters. Used in broad-spectrum sun screer and protective daily cosmetics.

(2)LGB® 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 LGB® ES with oil-soluble UV absorbers as LGB® OMC, LGB® OCR, LGB® OS, LGB® HMS or LGB® 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

(8)LGB® 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 LGB® ES can lead to a tremendous SPF boost, especially in combination with Polysilicone-15 but also with all other available sun filters combinations. LGB® ES can be used for water-based transparent sunscreen products such as gels or clear sprays.
