| Description |
Pigmented cosmetics and clay-based products have been identified as product categories that may contain toxic metals. The primary goal of this study is to evaluate the ability of available testing methods to detect lead, cadmium, and arsenic at low levels in selected cosmetic products. For this work, a comparison of preparatory digestion methods will be assessed. Additional work will include evaluation of certified or standardized reference materials and certain commonly used cosmetic ingredients, such as talc, bentonite, and synthetic mica, for reference and quality assurance purposes. |
