Chemspec CHEMSL HS (Ensulizole)

CHEMSL HS (Ensulizole) is an effective broad spectrum UV-B Filter. UV-A radiation (320-400nm) is linked with the loss of skin elasticity, wrinkling and premature aging, whilst the more powerful UV-B radiation (290-320nm) is linked to sunburn, whilst the more powerful UV-B radiation (290-320nm) is linked to sunburn, cell damage and cancer risk. Chemsol HS is a highly effective UV-B filter absorbing in the UV-B range (290-340nm). Chemsol HS is water-soluble, facilitating good incorporation particularly into high SPF skin care and sunscreen products where light, non-greasy feel is desired. For total UV-range protection, Chemsol HS is usually formulated with Chem 1789 (Avobenzone, UV-A blocking).
