Claims
- 1. A screening cosmetic composition comprising, in a cosmetically acceptable carrier, a zirconium oxide nanopigment having a mean diameter of less than 100 nm but greater than 5 nm, admixed with partially or completely neutralized 1,4-benzenedi(3-methylidene-10-camphosulfonic) acid of formula ##STR4## wherein A represents hydrogen, alkali metal or NH(R).sub.3 .sup.+, wherein
- said R's each independently represent hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 hydroxyalkyl or M.sup.n+ /n wherein M.sup.n+ is a polyvalent metal cation wherein n represents 2, 3 or 4.
- 2. The screening cosmetic composition of claim 1 wherein said zirconium oxide nanopigment has a mean diameter ranging from 5 to 50 nm.
- 3. The screening cosmetic composition of claim 1 wherein M.sup.n+ is a polyvalent metal cation selected from the group consisting of Ca.sup.2+, Zn.sup.2+, Mg.sup.2+, Ba.sup.2+, Al.sup.3+ and Zr.sup.4+.
- 4. The screening cosmetic composition of claim 1 wherein said zirconium oxide nanopigment is present in an amount ranging from 0.5 to 10 percent by weight relative to the total weight of said composition.
- 5. The screening cosmetic composition of claim 1 wherein said partially or completely neutralized 1,4-benzenedi(3-methylidene-10-camphosulfonic) acid of formula (I) is present in an amount ranging from 0.1 to 10 percent by weight relative to the total weight of said composition.
- 6. The screening cosmetic composition of claim 1 wherein said partially or completely neutralized 1,4-benzenedi(3-methylidene-10-camphosulfonic) acid/zirconium oxide nanopigment weight ratio ranges from 0.05 to 5.
- 7. The screening cosmetic composition of claim 1 comprising a form selected from the group consisting of a lotion, a thickened lotion, a gel, a vesicular dispersion, a cream, a milk, a powder, a solid stick, a foam and a spray.
- 8. The screening cosmetic composition of claim 7 which further contains a cosmetic adjuvant selected from the group consisting of a fatty substance; an organic solvent; a silicone; a thickener; a demulcent; a UV-A, UV-B or a broad-band sunscreen agent; an antifoaming agent; a moisturizing agent; a perfume; a preservative; a surface-active agent; a filler; a sequesterant; an anionic, cationic, nonionic or amphoteric polymer or a mixture thereof; a propellant; an alkalizing agent; an acidifying agent; a colorant and a metal oxide pigment having a particle size between 100 nm and 20,000 nm.
- 9. The screening cosmetic composition of claim 1 for protecting human epidermis against ultraviolet rays or an anti-sun composition or for the prevention of photodermatoses, said composition being in a form selected from the group consisting of a suspension or dispersion in a solvent or fatty substance; and emulsion; a vesicular dispersion; an ointment; a gel; a solid stick and an aerosol foam.
- 10. The screening cosmetic composition of claim 1 for protecting hair against ultraviolet rays, said composition being in a form selected from the group consisting of a rinse-off shampoo; a lotion; a gel (1) applicable before or after shampooing, (2) before or after dyeing or bleaching or (3) before, during or after permanent waving or hair straightening; a hair styling or treatment lotion or gel; a lotion or gel for blow-drying or hair setting; a hair lacquer; a permanent waving composition; a hair straightening composition; a hair dyeing composition and a hair bleaching composition.
- 11. The screening cosmetic composition of claim 1 comprising a make-up for eyelashes, eyebrows, skin or hair in a form selected from the group consisting of an epidermis treatment cream; a foundation; a lipstick; an eyeshadow; a blusher; an eyeliner; a mascara; and a coloring agent; said composition being provided in anhydrous or aqueous solid or pasty form.
- 12. A process for protecting the human epidermis and hair against ultraviolet radiation comprising applying to the skin or hair a cosmetically effective amount of said screening cosmetic composition of claim 1.
- 13. A process for preventing the development of photodermatoses comprising applying to the skin a cosmetically effective amount of said screening cosmetic composition of claim 1.
- 14. A process for reducing or inhibiting light-induced reaction of zirconium oxide nanopigments exposed to light comprising admixing said zirconium oxide nanopigments having a mean diameter less than 100 nm but greater than 5 nm, with partially or completely neutralized 1,4-benzenedi(3-methylidene-10-camphosulfonic) acid.
