- 4. A composition according to claim 1 wherein the polymeric particles are polymethyl methacrylate.
- 5. A composition according to claim 1 wherein the particles are cross-linked.
- 6. A composition according to claim 1 wherein the particles have an Oil Absorbance value ranging from about 100 to about 200 ml/100 gm.
- 7. A cosmetic composition comprising:(i) from about 0.1 to about 15% by weight of an organic sunscreen agent having a chromophoric group active within the ultraviolet radiation range from 290 to 400 nm; (ii) from about 0.01 to about 10% by weight of a water-insoluble powdered polymethyl methacrylate polymer formed as porous particles having an Oil Absorbance (castor oil) value ranging from about 100 to about 200 ml/100 gm; and (iii) from about 1 to about 99% of water, the composition having a pH ranging from about 1 to about 6.5.
