The textile industry has been known to use hazardous chemicals. However, it is undergoing a radical change towards clean production and sustainable practices in the past few years. The Greenpeace Detox campaign and the ZDHC Initiative of global Brands & Retailers has impacted chemical management systems at all tiers of the supply chain.

All stakeholders – from Chemical and Colorant Manufacturers, Wet Processors (such as mills, dyehouses, printing and garment washing units) to Cut & Sew Garment Exporters- need to check what chemicals are used in the production of garments and whether any hazardous chemicals are being discharged during the manufacturing stages.

Besides Brands & Retailers' chemical restrictions, global legislation and eco-labels regarding residues of harmful chemicals in finished articles and their discharge in wastewater and sludge are getting strict every day.

To meet these new challenges for hazardous chemical restrictions, NimkarTek has established a 'DETOX LABORATORY' at Thane, India to: help all stakeholders assess the risks in their chemical formulations & finished products provide solutions to achieve cleaner production and safer chemicals

NimkarTek Detox Laboratory has established state-of- the art equipment such as GC-MS, LC-MS, ICP-OES, UV-Vis. A new eco-toxicity section consists of equipment for Algal Inhibition Toxicity Testing, COD, BOD, Ready and Inherent biodegradability.

The laboratory has capability to test for restricted substances in substrates(garments, fabrics, yarns, fiber, accessories), colorant/chemical formulations and wastewater samples.

Restricted substance groups such as APEOs, Heavy metals (Total and Extractable), Chlorophenols, Chlorinated Aromatics, Phthalates, Banned amines from Azo dyes, PAHs, SCCPs, Formaldehyde and VOCs can be tested.

NimkarTek Detox Laboratory provides the following services:

For Garment Exporters and Wet Processing units

  1. Screening of finished products for conformance to Brand Chemical Restrictions (RSL/RSS): Global Brands & Retailers monitor chemical restrictions through their 'Restricted Substances List'(RSL) or Standard (RSS) which prescribe Limit Values for residues of the listed substances on the final article. NimkarTek offers testing ofAP/APEOs, Heavy metals (Total and Extractable), Chlorophenols, Chlorinated Aromatics, Phthalates, Banned amines from Azo dyes, PAHs, SCCPs, Formaldehyde and VOCs in the final articles

  2. Pre-screening for Eco-label criteria: Certification of Eco-labels (such as GOTS and OekoTex 100) need to be renewed annually as well as randomly monitored for conformity to their criteria on restricted substances in finished goods. NimkarTek offers testing for pre-screening your finished articles for these eco-label criteria so that you are sure of your certification approval. Major risk areas such as Chlorinated Aromatics, Chlorophenols, AP/APEOs, Formaldehyde and other short-chained aldehydes, Heavy metals, Banned amines from Azo dyes, AOX, PAH, Phthalates and SCCPs can be tested at our Detox Laboratory.

  3. Root Cause Analysis of chemical restriction failures: Non- conformance of a finished article to RSL or Eco-label criteria can impact your business. It is imperative that preventive actions are taken to ensure that the RSL failure does not recur in future. NimkarTek offers a helping hand for root cause analysis of RSL failures. Using our textile & analytical expertise and analyzing your processes and input chemical inventory, we can help you in reducing the samples for testing and thereby the testing costs.

  4. Testing of input chemical inventory for restricted chemical residues: Although chemical suppliers may not intentional use a restricted substance, unintentional residues or contaminations can remain in the formulations and may result in RSL failure of the final article. NimkarTek's Detox lab can screen the chemical inventory at a processing facility for these residues using a 'Smart' testing technique and ensure that the chemicals procured at the facility will

For Colorant and Chemical Manufacturers

  1. Screening of chemical and colorant formulations for the ZDHC MRSL: The Zero Discharge of Hazardous Chemicals (ZDHC) Group of apparel & footwear brands have developed a 'Manufacturing Restricted Substances List' or MRSL which details 16 Chemical Groups and their analytes that are restricted from usage in input colorant and chemical formulations. Limit values for unintentional contaminations of these analytes must be complied with by chemical suppliers. At NimkarTek Detox Laboratory, chemical and colorant formulations can be screened for conformance to the ZDHC MRSL residue limits and the manufacturer can declare a 'Positive List' of formulations to his clients.

  2. Testing for GOTS criteria for input chemicals: The Global Organic Textile Standard (GOTS) standard lists chemical inputs that may (potentially) be used in conventional textile processing but that are explicitly banned or restricted for environmental and/or toxicological reasons in all processing stages of GOTS Goods. The GOTS input chemical restrictions as well as toxicity parameters requirements can be tested and confirmed at NimkarTek Detox lab for submission to GOTS Certifying Agency.

  3. Safety Data Sheet (SDS) Authoring: SDS is a document that informs users about potential hazards in a chemical and instructions for safe handling and disposal. The Globally Harmonized System (GHS) and the EU Classification, Labelling and Packaging(CLP) has prescribed criteria for hazard classification &communication in an SDS. NimkarTek provides SDS Authoring services as per GHS guidelines to ensure that your SDS is complete information in all respects and meets global requirements for hazard communication.
