World over the industries, specifically, chemical suppliers, material suppliers, Textile and Leather product processors and finishers, brands and value chains and Testing and certification bodies aim towards “Cleaner production “. They intend to use “Cleaner Inputs”, so as to meet requirements of Eco labeling & Discharge standards which includes ZDHC (Zero discharge of Hazardous Chemicals) for chemical formulation and Waste water, GOTS (Global organic Textile Standards) , REACH regulations, OEKO-TEX , California Proposition 65 etc
Increasingly large numbers of chemicals have now been categorized as toxic, carcinogenic, allergenic or hazardous. Uses of such chemicals are undesirable and thus loosing favor.
The ZDHC programme has launched the ZDHC MRSL (manufacturing restricted substances list) list of chemical substances banned from intentional use, but may be found as unintended contaminants within a commercial chemical formulation utilized in facilities that process textile materials, synthetic leather, leather, and trim parts in textiles & footwear.
This includes not only chemical used specifically for production, but also cleaning supplies, machine cleaners, lubricants, etc. that are in use in the facility for maintenance and support.
The ZDHC conformance process offers brands, material suppliers, and product finishers a choice of recognised and accepted options to provide ZDHC certificates
Testtex India Laboratories Pvt Ltd , as recognized and accepted independent third party laboratory can help brands and their value chain by providing indicators in the form of test certificate that following chemical formulations will be in conformance to ZDHC MRSL requirements.
The ZDHC MRSL list of chemical substances banned from Intentional uses and should be tested for identification and quantification for ZDHC MRSL conformance requirements are as follows
With a “smart approach” testing, (every type of chemical formulation need not be tested for each MRSL parameter) Testtex team identifies probable hazardous substance depending upon type and end-use of chemical formulation and serves:-
Testtex Detox Team will review chemical formulations, identify hazardous substances to be tested, guide to fill up test request form and conduct tests for ZDHC MRSL conformance accordingly.
Testtex Detox Team will provide indicators in term of Test certificate along with Test report.
On conformance of Chemical formulation to ZDHC MRSL, Testtex Detox Team will send the Test certificate along with Test report to ZDHC.
Chemical / Formulation suppliers can upload the Test certificate along with Test report on the ZDHC Gateway - Chemical Module.
