Poorly water-soluble salts of organic acids, their use as sunscreen agents and sunscreen compositions comprising them. The salts are formed between an organic anion which displays ultraviolet absorption over at least a portion of the wavelength range from 290 to 400 nanometres, and a metal cation characterised in that the metal cation is one or a mixture of aluminium, zinc, titanium, tin, iron or lanthanum and the salt has a solubility of less than 2g/litre in water at 20 DEG C. |
