The invention claimed is: 1. A process for preparing a composition, comprising percolating a fluid, at a pressure of at least 3 bar, through at least one protective agent for keratin fibers, in solid or pasty form, wherein the at least one protective agent is selected from sunscreens, antioxidants,
The invention claimed is: 1. A process for preparing a composition, comprising percolating a fluid, at a pressure of at least 3 bar, through at least one protective agent for keratin fibers, in solid or pasty form, wherein the at least one protective agent is selected from sunscreens, antioxidants, anti-pollution agents, free-radical scavengers, and mixtures thereof. 2. The process according to claim 1, comprising percolating a fluid, at a pressure of at least 3 bar, through at least one sunscreen. 3. The process according to claim 2, wherein the at least one sunscreen is selected from anthranilates, cinnamic derivatives, dibenzoylmethane derivatives, salicylic derivatives, camphor derivatives, triazine derivatives, benzophenone derivatives, β, β-diphenylacrylate derivatives, benzotriazole derivatives, benzalmalonate derivatives, benzimidazole derivatives, imidazolines, bisbenzoazolyl derivatives, p-aminobenzoic acid derivatives, methylenebis(hydroxyphenylbenzotriazole) derivatives, benzoxazole derivatives, screening polymers and screening silicones, α-alkylstyrene-derived dimers, 4,4-diarylbutadienes, and mixtures thereof. 4. The process according to claim 1, comprising percolating a fluid, at a pressure of at least 3 bar, through at least one anti-pollution agent, wherein the at least one anti-pollution agent is selected from vitamin C and its derivatives, non-colouring phenols and polyphenols, epigallocatechin and natural extracts containing it, olive leaf extracts, tea extracts, anthocyanins, rosemary extracts, phenol acids, stilbenes, sulphur-containing amino acid derivatives, N-acetylcysteine, chelating agents, carotenoids, non-colouring indole derivatives, and mixtures thereof. 5. The process according to claim 1, comprising percolating a fluid, at a pressure of at least 3 bar, through at least one free-radical scavenger and/or antioxidant selected from vitamin E and its derivatives, flavonoids, bioflavonoids, coenzyme Q10 or ubiquinone, catalase, superoxide dismutase, lactoperoxidase, glutathione peroxidase and quinone reductases, glutathione, benzylidenecamphor, benzylcyclanones, substituted naplithalenones, pidolates; phytantriol, gamma-oryzanol, guanosine, lignans, melatonin, reductones and the derivatives thereof, including erythorbic acid, ascorbic acid and ascorbyl palmitate, sodium suiphite, and mixtures thereof. 6. The process according to claim 1, wherein the protective agent in solid or pasty form is present as a mixture with at least one adjuvant. 7. The process according to claim 6, wherein the adjuvant is selected from clays, salts, anionic, nonionic, cationic or zwitterionic surfactants, natural or synthetic thickeners, starch which optionally has been modified, glass beads, silica, nylon, alumina, titanium dioxide, zeolites, poly(methyl methacrylate) (PMMA), chitosan, maltodextrin, cyclodextrin, mono-or disaccharides, zinc oxide, zirconium oxide, resin particles such as silicone or silica beads, talc, polyaspartic acid, borosilicates, especially calcium borosilicate, polyethylene, cotton, polytetrafluoroethylene (PTFE), cellulose and its derivatives, superabsorbent compounds, magnesium carbonate or calcium carbonate, maize seeds, polydimethylsiloxane gums, polyacrylamide, porous hydroxyapatite, silk, collagen, sawdust, fucus powder, flours or extracts of wheat, rice, pea, lupin, soya or barley, crosslinked polyvinylpyrrolidone, calcium alginate, activated carbon, poly(vinylidene chloride/acrylonitrile) particles, and mixtures thereof. 8. The process according to claim 6, wherein the protective agent or agents are present in an amount ranging from 0.5% to 99% by weight relative to the total weight of protective agent(s) and adjuvant. 9. The process according to claim 1, wherein the percolation step is performed with a fluid under a pressure of 3-30 bars. 10. The process according to claim 1, wherein the fluid comprises steam. 11. The process according to claim 10, wherein the fluid is steam accompanied by liquid water. 12. The process according to claim 1, wherein the fluid comprises one or more cosmetically acceptable gaseous and/or liquid organic solvents. 13. The process according to claim 1, wherein said composition is devoid of preservative. 14. A process, comprising preparing a composition comprising percolating a fluid, at a pressure of at least 3 bar, through at least one protective agent for keratin fibers, in solid or pasty form, and to apply said composition to keratin material. 15. The process according to claim 14, wherein the composition is applied to keratin fiber by a device which does not require human intervention. 16. A process according to claim 14, wherein, before application, the composition is mixed with a cosmetically acceptable medium and/or with one or more additives used in cosmetics, and or with another composition prepared by a process comprising percolating a fluid, at a pressure of at least 3 bar, through at least one protective agent for keratin fibers, in solid or pasty form. 17. A process according to claim 14, wherein the compositon is applied in an amount effective to resist pollution, development of greasiness, UV radiation, light, free radicals and/or chlorine. 18. A device for packaging a composition, comprising a closed housing delimited by at least one wall that is at least partially permeable to fluid at a pressure of at least 3 bar, the device having therein a composition comprising at least one protective agent for keratin fibers, in solid or pasty form, the device being optionally delimited by two sealed sheets or by a tray closed with a lid, wherein the at least one protective agent is selected from sunscreens, antioxidants, anti-pollution agents, free-radical scavengers, and mixtures thereof.
