Sarex's Sarasorb range includes several second-generation (next-generation) UV filters — including BEMT, DHHB, DHBT, and MBBT — engineered for broader UVA/UVB coverage, higher photostability, and lower usage concentrations compared to first-generation filters like OMC and EHS. These next-generation actives are increasingly preferred by formulators developing modern, dermatologically elegant sunscreen and daily-wear SPF products.
