Screening cosmetic composition containing a mixture of 1,4-benzenedi
(3-methylidene-10-camphosulfonic) acid, partially or completely
neutralized, and metal oxide nanopigments
摘要:
The invention relates to a screening cosmetic composition comprising, in a mixture, 0.5 to 10% by weight of metal oxide nanopigments chosen from titanium, zinc, cerium or zirconium oxide or mixtures thereof, with a mean diameter of less than 100 nm, and 0.1 to 10% by weight of 1,4-benzenedi(3-methylidene-10-camphosulfonic) acid or one of its alkali metal, ammonium, amine, alkanolamine, Ca, Zn, Mg, Ba, Al or Zr salts, in a cosmetically acceptable carrier. This composition is useful as composition for protecting the human epidermis or the hair against UV rays or as make-up.
