The invention relates to a cosmetic light screening composition containing, in an aqueous phase, about 0.5% to about 10 wt % of 2-phenylbenzimidazol-sulphonic acid or a salt thereof and at least one fatty phase, including about 1% to about 30 wt % of a linear or cyclic polysiloxane compound of the general formula Ia or Ib: wherein x is R or A; A is a group selected from the formula IIa, IIb or IIc; R is hydrogen, C1-6 alkyl or phenyl; R1 and R2 are each independently hydrogen, hydroxy, C1-6-alkyl or C1-6-alkoxy; R3 is C1-6-alkyl; R4 is hydrogen or C1-6-alkyl; R5 and R6 are each independently hydrogen or C1-6-alkyl; r is from 0 to 250; s is from 0 to 20; r+s is at least 3; t is from 0 to 10; v is from 0 to 10; v+t is at least 3; n is from 1 to 6; and when s is 0, at least one X is A. Methods of using such compositions are also provided. |
