1

Background

The ZDHC Manufacturing Restricted Substances List (ZDHC MRSL) is a list of chemical substances banned
from intentional use in the processing of textile materials, leather, rubber, foam, adhesives and trims
used in textiles, apparel, and footwear industry. Intentional use means the substance used deliberately ina chemical product to achieve a desired look or functionality.
The ZDHC MRSL goes beyond the traditional approaches to chemical restrictions, which only apply tofinished products ( Restricted Substances List - RSL) and is focused on consumer safety. The MRSL
approach also helps protect workers, local communities, and the environment from the possible impactsof harmful chemicals.
Chemical formulations covered by restrictions in the ZDHC MRSL include, but are not limited to, cleaners,
adhesives, paints, inks, detergents, dyes, colourants, auxiliaries, coatings and finishing agents used during
raw material production, wet processing, process machinery maintenance, wastewater treatment,
sanitation, and pest control. ZDHC MRSL limits apply to substances in commercially available
formulations, not those from earlier stages of chemical synthesis.
Using chemical formulations that conform to the ZDHC MRSL allows suppliers to assure themselves, andtheir customers, that banned chemical substances are not intentionally used during production andmanufacturing processes.
The ZDHC Roadmap to Zero Programme would like to acknowledge the vital role of the experts
comprising the MRSL Council who independently and objectively evaluated the proposed additions/revisions to the ZDHC MRSL V3.0 and made decisions.

2

PurposeThe ZDHC MRSL offers brands and suppliers a single, harmonised list of chemical substances banned
from intentional use during manufacturing and related processes in supply chains of the textile, apparel,and footwear (including leather,rubber and foam) industries (the Industry).
Version 3.0 applies to textiles, leather, rubber, foam and adhesives. Recognising that these materials use
different processes, search filters can be used to search the limits for each material.
The ZDHC MRSL does not replace legal or brand-specific restrictions on harmful substances in materials
or finished products.

NOTES

The ZDHC MRSL 3.0 published by ZDHC Foundation does not guarantee the following:
Compliance with, or to take the place of, legal or regulatory requirements. Examples might include:
stricter legal, local or regional regulatory requirements on the use, storage and transport of chemical
products; or other requirements relating to the handling and disposal of chemical products, which shallsupersede any requirements as set forth in this document.
Compliance with, or conformance to, any national or international environmental or workplace safety
requirements, including, but not limited to, relevant regulations and/or standards.
Nor do the ZDHC MRSL 3.0 replace any national or international environmental or workplace safety
requirements including, but not limited to, regulations and/ or standards.
The ZDHC MRSL 3.0 is not intended nor can be used as a statement of legal requirements.

ZDHC Manufacturing Restricted Substances List (ZDHC MRSL) V3.0 Nov 2022 (All rights reserved)

ZDHC refers to the UN GHS (Globally Harmonized System of Classification and Labelling of Chemicals) as
the internationally recognised standard for hazardous material classification and labelling. All the other
National/Regional existing schemes, derived from the implementation of the GHS, have to be considered
included in the list of the accepted ZDHC standards for this purpose. To simplify the ZDHC MRSL 3.0
comprehension, ZDHC uses GHS throughout as its reference for Hazard Statements and Pictograms in
SDS and labels in order to avoid local variables.

ZDHC MRSL Chapters

5.1

Chapter 1: ZDHC MRSLThis applies to chemical formulations and substances used during the creation and wet processing of
textile fibres, and during the creation and processing of (coated) fabrics, leather, rubber, foam andadhesives.
The MRSL substances are listed with applicable CAS numbers and provided with Applicability filters for
substrates (Textile, Leather, Polymers -Rubber, Foam, Adhesives), Supplier Guidance, Formulation Limit
and Methods of Analysis.
Supplier Guidance includes:- No intentional use: these substances are banned from intentional use in facilities that process raw
materials and manufacture finished products- Not applicable: these substances are not applicable to the specific substrates- No restriction: these substances are not restricted for the specific substrates
Formulation limits are concentration limits for the substances in commercial chemical formulations
available from chemical manufacturers. These limits ban intentional use while allowing for reasonable
expected manufacturing impurities, which should be consistently achievable by responsible chemical
manufacturers.
Methods of Analysis describe general techniques of testing and wherever available, specific test methods.
In the ZDHC MRSL Table, R,F,A stands for Rubber, Foam and Adhesives.

5.2

Chapter 2: ZDHC MRSL Candidate List

Substances proposed for addition to the ZDHC MRSL update, as described in the Principles andProcedures, as they lack safer alternatives at scale or more information on the same needs to becollected. Substances on the Candidate List encourages the innovation of alternatives.

5.3

Chapter 3: ZDHC MRSL Archived Substances

Substances without strong evidence of current use in Industry, but with clear evidence of historical use.
The Archived Substances should not be reintroduced by a chemical manufacturer in their commercial
chemical products. This list should be reviewed by ZDHC Approved MRSL Certifier through the chemical
product’s Safety Data Sheet or any other relevant document to confirm absence of these substances in
the chemical formulation that is being certified for ZDHC MRSL Conformance.

Process for ZDHC MRSL Revision

The ZDHC MRSL is a living document and since its initial release in 2015 the ZDHC MRSL has been
regularly
updated.
The
updateprocess
isdescribed
here(https://downloads.roadmaptozero.com/input/ZDHC-MRSL-Principles-and-Procedures)

7

Transition Period

After the release of a new version of the ZDHC MRSL a transition period applies. This lets the Industry
prepare for the implementation of the new version. The current transition period is twelve months,
beginning on 01 November 2022. During this time, both versions of the ZDHC MRSL remain active and it’s
possible to certify against them.

1F. Dyes - Allergenic Disperse Dyes
Potential Uses
Disperse dyes are a class of water- insoluble dyes that penetrate the fibre system of synthetic or manufactured fibres and are held in place by physical forces
without forming chemical bonds. Disperse dyes are used in synthetic fibre dyeing (e.g. polyester, acetate, polyamide). Restricted disperse dyes are suspected of
causing allergic reactions and should no longer be used for dyeing of textiles.

Chemicals1F. Dyes - Allergenic Disperse Dyes
Potential Uses
Disperse dyes are a class of water- insoluble dyes that penetrate the fibre system of synthetic or manufactured fibres and are held in place by physical forces
without forming chemical bonds. Disperse dyes are used in synthetic fibre dyeing (e.g. polyester, acetate, polyamide). Restricted disperse dyes are suspected of
causing allergic reactions and should no longer be used for dyeing of textiles.

1J. Halogenated Solvents
Potential Uses
In apparel and footwear, halogenated solvents are used as finishing/ cleaning and printing agents, for dissolving/ diluting fats, oils and adhesives (e.g. in
degreasing or cleaning operations).
Formulations containing any of the listed solvents above the published limits are NON CONFORMANT with the ZDHC MRSL. Despite the advancement of waterbased systems, there are a small number of solvent-based systems that remain the most prevalent in the industry and ZDHC recognises that it will take time tophase these out completely.
ZDHC guidance is to avoid the deliberate use of listed solvents wherever possible, with a transition to water-based formulations being preferable, and to ensurethat worker exposure and emissions are minimised.
It is intended that the ZDHC Supplier Platform will assess the implementation of best practices for emission and exposure control as well as the usage of waterbased formulations at a facility.
Note: There are some solvent-based technologies that are generally regarded as having lower overall environmental impacts than aqueous alternatives (e.g.
solvent scouring) and every specific scenario will be judged on its merits through the ZDHC Supplier Platform.

1J. Halogenated Solvents
Potential Uses
In apparel and footwear, halogenated solvents are used as finishing/ cleaning and printing agents, for dissolving/ diluting fats, oils and adhesives (e.g. in
degreasing or cleaning operations).
Formulations containing any of the listed solvents above the published limits are NON CONFORMANT with the ZDHC MRSL. Despite the advancement of waterbased systems, there are a small number of solvent-based systems that remain the most prevalent in the industry and ZDHC recognises that it will take time tophase these out completely.
ZDHC guidance is to avoid the deliberate use of listed solvents wherever possible, with a transition to water-based formulations being preferable, and to ensurethat worker exposure and emissions are minimised.
It is intended that the ZDHC Supplier Platform will assess the implementation of best practices for emission and exposure control as well as the usage of waterbased formulations at a facility.
Note: There are some solvent-based technologies that are generally regarded as having lower overall environmental impacts than aqueous alternatives (e.g.
solvent scouring) and every specific scenario will be judged on its merits through the ZDHC Supplier Platform.

Potential Uses
Organotins are a class of chemicals combining tin and organics such as butyl and phenyl groups. Organotins are predominantly found in the environment as
antifoulants in marine paints, but they can also be used as biocides (e.g. antibacterials), catalysts in plastic and glue production and heat stabilisers inplastics/rubber. In textiles and apparel, organotins are associated with plastics/rubber, inks, paints, metallic glitter, polyurethane products and heat transfer
material.

Used in the manufacture of Indigo and some azo dyes. Residues from manufacturing can remain in the formulation. For all dyes otherthan indigo, it is important that non-reductive methods are used so that only the free aniline is analysed rather than that which could beformed by the cleavage of a dye molecule. For indigo, aniline can be tied up in insoluble clusters of dye and so a reductive method thatfully solubilises the dye and liberates free aniline is used. The levels of aniline in indigo must be achieved by removal of the aniline andnot by dilution, with a minimum indigo content of 30% being required.

1N. Perfluorinated and Polyfluorinated Chemicals (PFAS)
Potential uses
Formulations containing PFAS (Per and Polyfluorinated alkylated substances) are often used for water or stain repellency.
The use of any formulation based on, or including PFAS, including those listed below, is not permitted (for fashion, sport or outdoor clothing and apparel andhome textiles).
It should be noted that there may be certain critical (technical textile) end uses where legally or contractually mandated standards may only be achieved using
these substances (e.g. military, medical, protective clothing, transportation). The formulations will always be deemed ZDHC MRSL NON-CONFORMANT and it isintended that the ZDHC Supplier Platform will appraise the end uses of any PFAS within an inventory.
Note on PFAS and testing: There are thousands of individual chemicals that are categorised as PFAS but only a few are actually useful in terms of oil / water
repellency and their use is always accompanied by the presence of common, known 'marker' chemicals such as those listed below. ZDHC approved MRSL
certifiers will check for the deliberate use of PFAS or high levels of contamination of PFAS by testing for the marker chemicals listed below and ,at theirdiscretion, use a screening test for total fluorine (quantification limit: 50mg/kg) followed by confirmatory testing for specific series e.g. the other PFAS
mentioned in the PFAS ZDHC Guidance Sheet. ZDHC approved MRSL certifier reserves the right to request or carry out test for any specific PFAS chemical using

1N. Perfluorinated and Polyfluorinated Chemicals (PFAS)
Potential uses
Formulations containing PFAS (Per and Polyfluorinated alkylated substances) are often used for water or stain repellency.
The use of any formulation based on, or including PFAS, including those listed below, is not permitted (for fashion, sport or outdoor clothing and apparel andhome textiles).
It should be noted that there may be certain critical (technical textile) end uses where legally or contractually mandated standards may only be achieved using
these substances (e.g. military, medical, protective clothing, transportation). The formulations will always be deemed ZDHC MRSL NON-CONFORMANT and it isintended that the ZDHC Supplier Platform will appraise the end uses of any PFAS within an inventory.
Note on PFAS and testing: There are thousands of individual chemicals that are categorised as PFAS but only a few are actually useful in terms of oil / water
repellency and their use is always accompanied by the presence of common, known 'marker' chemicals such as those listed below. ZDHC approved MRSL
certifiers will check for the deliberate use of PFAS or high levels of contamination of PFAS by testing for the marker chemicals listed below and ,at theirdiscretion, use a screening test for total fluorine (quantification limit: 50mg/kg) followed by confirmatory testing for specific series e.g. the other PFAS
mentioned in the PFAS ZDHC Guidance Sheet. ZDHC approved MRSL certifier reserves the right to request or carry out test for any specific PFAS chemical using
appropriate test method to check MRSL conformance.

Potential Uses
Formaldehyde can be used or present in many types of formulations such as fixatives, resins and binders.
Substance

Formaldehyde

CASNO

50-00-0

Intent

Where formulations that contain formaldehyde are used, it is expected thatappropriate exposure and emission controls are employed.
In version 4 of the ZDHC MRSL, it is intended to introduce a maximum
allowable limit of 250 mg/kg formaldehyde for the majority of formulations
and appropriate test methods for leather and textile formulations will need to
be determined.
For formulations that are known to contain formaldehyde at higher levels but
represent state-of-the-art technology, such as non-iron and easy to iron finish
formulations or reactive organic / resin tanning agents, it is intended to
introduce a limit of 1000 mg/kg in conformance with hazard labelling
obligations.

2E. Potassium Permanganate
Potential Uses
Potassium Permanganate is primarily used for localised bleaching of denim using a spraying process.
Substance

Potassium
permanganate

CASNO

7722-64-7

IntentPotassium permangante must never be used without appropriate engineering
controls (such as water curtains and localised extraction) and workers must
always use appropriate personal protective equipment. Suppliers are strongly
encouraged to evaluate alternatives to manual spraying of potassium
permanganate - such as lasers, robotised spraying or safer chemicalalternatives

2F. Solvents
Potential Uses
There are many uses of solvents including cleaning, coatings, prints.
Many solvents are restricted in the main list of the ZDHC MRSL. It is strongly advised that suppliers actively seek safer alternatives to the solvents listed in thecandidate list as these may be placed on the main list in future versions of the ZDHC MRSL.
Substance

CASNO

Intent2-Methoxypropanol

1589-47-5

It is intended to introduce a limit for leather formulations in the ZDHC MRSL
version4.

Methanol

67-56-1

Methanol is a concern because of its toxicity and in ZDHC MRSL version 4.0 it
is intended to introduce maximum allowable limits and encourage
substitution by safer solvents, which in many cases will be ethanol. However,
we are aware that human consumption of industrial ethanol can be a problem
and there is a requirement in some jurisdictions for industrial ethanol to bedeliberately ‘tainted’ with methanol to make it undrinkable. This will need tobeconsidered
as
we
draw
up
recommendations.
