A química e toxicidade dos corantes de cabelo
(Sociedade Brasileira de Química, 2014-07-01)
The market for hair dye involves a growing range of products, which requires greater understanding of hair properties, mechanisms of action and color development. In this work, we present a critical analysis of the ...
Use of a composite electrode modified with magnetic particles for electroanalysis of azo dye removed from dyed hair strands
(2016-12-01)
The analysis of dyes in hair samples can provide useful information for forensic purposes. The present work describes a novel method for the extraction of dye from a hair sample and its determination using a composite ...
Application of voltammetric technique to the analysis of indanthrene dye in alkaline solution
(Elsevier B.V., 2006-01-01)
The Indanthrene Olive Green B (C.I. Vat Green 3; C.I. 69500), VG3 dye, a vat dye bearing an anthraquinonoid group and a ketonic group, can be detected by differential pulse voltammetry in alkaline solution using glassy ...
