MRSL Testing Services

MRSL testing (Manufacturing Restricted Substances List testing) is an essential component of chemical risk management, focusing further upstream in the supply chain (beyond Restricted Substance Lists (RSL) testing). Testing chemicals to an MRSL analyses chemical formulations that are used in the manufacture of materials (leather, textiles and synthetics).

Eurofins | BLC has developed the testing of chemicals to an MRSL to include a series of fully validated test methods. These test methods are then used to determine the quantity of individual chemicals within a supplied chemical formulation, against those listed on the Zero Discharge of Hazardous Chemicals (ZDHC) MRSL.

Testing chemicals to an MRSL involves specialised chemical extraction and clean-up processes, which are dependent upon the product formulation.

Eurofins | BLC Chem-MAP is approved by ZDHC to provide MRSL testing, as part of the c-MAP Programme within the Chem-MAP family. However, Eurofins | BLC can also carry out bespoke MRSL testing, outside of the standard c-MAP Programme (if required).

The following MRSL testing packages are available:

Package 1 — Complete MRSL Testing of Chemical Formulations

A complete testing programme for chemical formulations, testing individual chemical formulations used in the manufacture of leather, synthetic leather and textiles, against all chemicals listed in the ZDHC MRSL (over 140 individual chemical tests).

Package 2 — ‘Smart Testing’ of Chemical Formulations

Chemical formulations are evaluated, and ‘smart tested’ against ZDHC MRSL chemical groups, that are most likely associated with the formulation of the product, and therefore present an increased risk. Chemical groups that present a low risk (those that are unlikely to be used in the product formulation), are excluded from ‘smart testing’.

Package 3 — MRSL Testing of Individual Analytes or Chemical Groups

Chemical formulations can be tested for individual analytes or chemical groups listed in the ZDHC MRSL upon request.

Package 4 — Customer Specified MRSL Testing

If your company has their own MRSL (with specified limits), Eurofins | BLC can carry out bespoke MRSL testing of your chemical formulations upon request (please note for this testing turnaround times may be subject to change).
