PROBLEM TO BE SOLVED: To obtain a treated powder capable of providing a cosmetic excellent in sebum resistance, water resistance and durability by formulating with a cosmetic by carrying out a surface treatment with a specific silicone compound modified with a fluorinated alkyl in combination with a (poly)glycerin. SOLUTION: This treated powder is obtained by carrying out a surface treatment of (A) an inorganic or organic powder optionally subjected to a silicone treatment, a pendant treatment, etc., with (B) 0.1-100 wt.% silicone compound modified with a fluorinated alkyl in combination with a (poly)glycerin, of formula I R<1> to R<12> is each a 1-10C alkyl or a phenyl with the proviso that one or more of the R<1> to R<12> is a fluorine-substituted alkyl, and further another one or more thereof is formulas II to IV [Q is a 1-10C divalent hydrocarbon; (1) us 1-20; (m) is 1-20]; (p), (q) and (r) each >=0. and when (p)=(q)=0 and (r)≠0, one or more of R<1> to R<3> and R<8> to R<12> are each a fluorine-substituted alkyl and formulas II to IV, and when (p)=(r)=0 and (q)≠0, one or more of R<1> to R<3> , R<6> to R<7> and R<10> to R<12> are each a fluorine-substituted alkyl and formula II to IV} based on the component A.
