  • Patent number: 4912241
    Abstract: Organosilicon compounds having at least one unit of the general formula ##STR1## in which R represents alkyl, R' is a divalent alkylene, oxyalkylene, alkenylene or oxyalkenylene, Z represents an alkyl, alkoxy or hydroxyl group, a has a value of 0, 1, 2 or 3 and c is 0 to 1, wherein at least one of Z and R' is linked to the multivalent aryl group via an ether linkage, are useful for absorbing UV radiation. Especially if polymeric (with e.g. diorganosiloxane units) they can be incorporated in sunscreen preparations to improve their substantivity to the skin. A process for preparing the compounds is also disclosed.
