The invention provides a conjugate comprising a hyperbranched polymer covalently bonded to at least three UV absorbing chromophores having an UV absorption maximum λ
max
>270 nm.
The conjugate is an effective and safe sunscreen which can advantageously be used in cosmetic compositions.

The invention relates to an apparatus for removal of ions, the apparatus being provided with a housing. The apparatus comprises: a water inlet for letting water in the housing; a water outlet for letting water out of the housing; a first and second electrode; a spacer between the first and second electrode for allowing water to flow in between the first and second electrode; and, an ion exchange membrane between the first and/or second electrode and the spacer; wherein the membrane comprises a crosslinked hyperbranched polymerwith ion exchange groups.
