DyStar Phases Out Color Index to Improve Eco Offering

DyStar Group, a leading provider of dyes, performance chemicals and color solutions for the textile industry, is nixing its oft-used Color Index in an effort to improve its ecological differentiation.

The Color Index is a reference list of manufactured colorants including pigments and dyes, published by the Society of Dyers & Colourists (SDC) and the American Association of Textile Chemists & Colorists (AATCC), that textile sector manufacturers use to identify colorants.

However, DyStar said it now wants to move away from the Color Index nomenclature in favor of its own trademarks and product identifiers to differentiate itself from companies that could be compromising on environmental matters.

According to a company statement, “The Color Index lists products based on general chemical structure, but is missing environmental and ecology factors which are becoming increasingly important for product selection. There are few limitations on the usage by manufacturers of the Color Index. As a consequence, it doesn’t guarantee compliance with international regulations or place restrictions on potential contaminant substances.”

This can be a problem for both the buyer and the seller, DyStar said, as being listed in the Index doesn’t necessarily mean products don’t contain chemicals subject to restriction by legislation or by voluntary initiatives like the Zero Discharge of Hazardous Substances group’s Manufacturing Restricted Substances List (ZDHC MRSL).
