ELIMINATION OF FREE FORMALDEHYDE IN LEATHER BY VINCA ROSEA AND CAMELLIA SINENSIS EXTRACTS

摘要

Even though modern technologies are applied, many chemicals that are hazardous to the environment and human health are used during the leather processing. Formaldehyde is one of the chemicals known to exhibit carcinogenicity. In this research, elimination of free formaldehyde in leather by the application Vinca rosea and Camellia sinensis extracts was investigated. Formaldehyde was quantified with two methods; Draft IUC 19 (HPLC) method and AATCC test method 112. When measured by each method Camellia sinensis extract provided the lowest formaldehyde content in leathers.
