SURVEY OF COSMETICS FOR SEVEN INORGANIC ELEMENTS 133 was 100 mg/kg (Absolute Standards, Hamden, CT). Trace metal grade acids (nitric, hydrofl uoric, and hydrochloric) and reagent chemicals (hydroxylamine hydrochloride, stannous chloride, potassium bromide, potassium bromate) from Fisher Scientifi c (Pittsburgh, PA) and EMD Chemicals (Gibbstown, NJ) were used to prepare the fol- lowing standard, stock, sample, and reagent solutions: 25% hydroxylamine hydrochlo- ride (w/v) in 1% HCl, 25% stannous chloride (w/v) in 15% HCl, and bromine monochloride solution (1.5% potassium bromide and 1.1% potassium bromate in con- centrated HCl). Standard reference materials used were SRM 1643e, water SRM 1641d, mercury in water SRM 2702, inorganics in marine sediment SRM 695, trace elements in multi-nutrient fertilizer and SRM 1573a, tomato leaves, all obtained from the National Institute of Standards and Technology (Gaithersburg, MD). Custom oil- based standards used were Conostan Oil Standard containing 1 μg/g As, Pb, Cd, and 5 μg/g Cr, Co, and Ni, obtained from SCP Science (Champlain, NY) and Mercury Custom Oil Standard containing 5 μg/g Hg, obtained from SPEX CertiPrep, Inc.

JOURNAL OF COSMETIC SCIENCE 134 (Metuchen, NJ). A diluting solution of 1% HNO3 + 0.5 % HCl (v/v) was used for preparing calibration standards and analytical solutions. CALIBRATION STANDARDS FOR ICP-MS ANALYSES Calibration standards were prepared to contain the nominal concentration of each ele- ment to four signifi cant fi gures as shown in Table I. CALIBRATION STANDARDS FOR CVAFS MERCURY ANALYSES Mercury standards were prepared daily from dilution of the primary stock standard to 0.5, 1, 5, 2, and 40 ng/kg. A secondary check solution was made from dilution of the secondary stock standard to 5 ng/kg. Table XII.
