Abstract
The invention comprises compounds of the general formula <FORM:0928162/IV(a)/1> (wherein R represents a C1-6 alkyl radical and n is an integer from 1 to 10), and the preparation thereof by the action of appropriate alkylating agents on the corresponding dihydroxy compounds (R = H). The products are useful as ultra-violet absorbents in anti-sunburn preparations (see Group VI). Specification 928,161 is referred to.ALSO:Compounds of the general formula <FORM:0928162/VI/1> (wherein R represents a C1-6 alkyl radical and n is an integer from 1 to 10) have ultra-violet absorbing properties and high solubility in non-polar solvents and oils, and are thus useful in certain lotions and emollients such as anti-sunburn preparations.
