7. The cosmetic treatment method, according to claim 1, wherein the coated content of the at least one coated pigment and/or the at least coated mineral filler is from 0.1% to 4% by mass based on the total mass of said composition.

8. The cosmetic treatment method according to claim 6, wherein the hydrophobic or lipophilic-treating agent represent from 0.1 to 50% by mass of the total mass of the coated pigment and the coated mineral filler.

9. The cosmetic treatment method according to claim 1, wherein the composition comprises a least one sequestering agent.

10. The cosmetic treatment method according to claim 1, wherein the composition comprises a least one sequestering agent selected from ethylene diamine tetraacetic acid (EDTA), glucono delta-lactone, sodium gluconate, potassium and/or calcium; citric acid, phosphoric acid, tartaric acid, potassium bitartrate, sodium acetate, sorbitol and any combination thereof.

11. The cosmetic treatment method, according to claim 1, wherein the composition comprises a sequestering agent from 0.01% to 1% by mass based on the total mass of said composition.
