粉餅、眼影餅類化粧中含鉛量之調查檢驗

INVESTIGATION ON LEAD CONTENT OF MARKETING COSMETICS OF FACE POWDERS AND EYESHADOWS

粉餅、眼影餅類化粧品，經過氧化氫濕式分解法，及DDTC-MIBKK萃取鉛離子後，再以原子吸光法（Atomic absorption spectrophotometry）測定其中鉛含量。結果市售粉餅、眼影餅類化粧品之含鉛量大部份在20ppm以下，而外銷退貨品竟高達2450～4403ppm，經試行探討其原因。鍵語：粉餅、眼影餅類化粧品，DDTC-MIBK或APDC-MIBK，萃取法，原子吸光法鉛含量調查檢驗。 In last few years, our exported cosmetic goods of some face powders back due to high content of lead or chromium, and international trade of cosmetics was affected. For futher studying this incident in marketing cosmetics, the collected samples were decomposed, the residues were extracted by following DDTC-MIBK or APDC-MIBK procedures. The lead content of the extracts was then determined by atomic absorption. The results indicated that the domestical face powders and eyeshadows contained less than 20 ppm of lead, and the drawn shipments contained 2450 - 4403 ppm of lead.
