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.

1H. Flame Retardants

Potential Uses
Flame retardant chemicals are deliberately applied to meet legal and contractual flammability standards.
The use of the flame retardants listed below, or any halogenated flame retardant, is not permitted (for fashion, sport or outdoor clothing and apparel and home 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 is intended that the ZDHC Supplier Platform will appraise the end uses of any flame retardants within an inventory.

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 water-based 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 to phase 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 ensure that 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 water-based 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.

1L. Organotin Compounds

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 in plastics/rubber. In textiles and apparel, organotins are associated with plastics/rubber, inks, paints, metallic glitter, polyurethane products and heat transfer material.

* In order to be able to optimise performance characteristics of some leather finishes, it is sometimes desirable to use PU thickeners and create formulations on-site rather than purchasing pre-mixed formulations from chemical suppliers. In these instances, there is a more lenient limit of DBT for the thickeners themselves, but the thickeners must not be used in quantities >20% in tailored formulations.

(See notes below)
Used in the manufacture of Indigo and some azo dyes. Residues from manufacturing can remain in the formulation. For all dyes other than indigo, it is important that non-reductive methods are used so that only the free aniline is analysed rather than that which could be formed by the cleavage of a dye molecule. For indigo, aniline can be tied up in insoluble clusters of dye and so a reductive method that fully solubilises the dye and liberates free aniline is used. The levels of aniline in indigo must be achieved by removal of the aniline and not 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 and home 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 is intended 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 their discretion, 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.

1P. Polycyclic Aromatic Hydrocarbons (PAHs)

Potential Uses
Oil containing PAHs are added to rubber and plastics as a softener or extender and may be found in rubber, plastics, lacquers, and coatings. Within the footwear producing industry, PAHs are often found in the outsoles of footwear and in printing pastes for screen prints. PAHs can be present as impurities in carbon black dyestuffs.

1Q. Restricted Aromatic Amines (Cleavable from Azo-colourants)

Potential Uses
Azo dyes and pigments are colourants that incorporate one or several azo groups (-N=N-) bound with aromatic compounds. Thousands of azo dyes exist, but only those that degrade to form the listed cleavable amines are restricted. Azo dyes that release these amines are regulated and should no longer be used for dyeing of textiles or leather.
The four substances listed below highlighted with an asterisk are salts.

1R. Total Heavy Metals

The formulation limits for As, Cd, Hg, Pb, and Cr (VI) in the list below apply to all types of formulation. When a limit for pigments is specific and differs from the general limit, it is denoted by brackets. The formulation limits for Sb, Cr, Ba, Se, Sn, Ni, Cu, Co and Ag only apply to dye and/or pigment formulations. Any differences between limits for dyes and pigments are indicated in the formulation limit column. The limits for the heavy metals do not apply to colourants containing a listed metal as an inherent compositional part (e.g. metal-complex colourants, the double salts of certain cationic colourants or extenders like barium sulfate). Wet processors must be aware of the metal limits in the ZDHC wastewater guidelines as well as the brand RSL limits with regard to extractable metals from dyed materials when using any colourant that has listed metals as an inherent compositional part. Where RSL and/or wastewater issues are observed, wet processors should discuss this with supply chain partners.

Potential Uses
Although typically associated with leather tanning, chromium VI also may be used in the dyeing of wool (after chroming process).

2A. Bisphenols

Substance CASNO Intent
Bisphenol AF
Bisphenol F
Bisphenol S
1478-61-1
620-92-8
80-09-1
Numerous bisphenols, including those listed, are under investigation; based on the information available and their legal status, they may be added to the main list of ZDHC MRSL version 4.0 in the future.

2B. Ethoxylated Tallow Amine

Substance CASNO Intent
Polyethoxylated tallow amine 61791-26-2 More information is required on specific substances in this group of chemicals to make a jugment on restrictions

2C. Formaldehyde

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

Substance CASNO Intent
Formaldehyde 50-00-0 Where formulations that contain formaldehyde are used, it is expected that appropriate 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.

2D. Phenol

Potential Uses
Phenol is not deliberately used in textiles or footwear but trace amounts of phenol can be found in many chemical formulations.

Substance CASNO Intent
Phenol 108-95-2 ZDHC is looking for safe limits for phenol as a contaminant in textile chemical formulations.

2E. Potassium Permanganate

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

Substance CASNO Intent
Potassium permanganate 7722-64-7 Potassium 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 chemical alternatives

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 the candidate list as these may be placed on the main list in future versions of the ZDHC MRSL.

Substance CASNO Intent
2-Methoxypropanol 1589-47-5 It is intended to introduce a limit for leather formulations in the ZDHC MRSL version 4.
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 be deliberately ‘tainted’ with methanol to make it undrinkable. This will need to be considered as we draw up recommendations.

2G. Total Heavy Metals

Potential Uses
In addition to being used in dyes and pigments, metals are used as raw material for trims and other components.

Substance CASNO Intent
Multiple Metals (Non-dye /pigment) Studies on usage patterns of metal containing chemicals and formulations and the potential effect of restrictions are will be monitored on an on-going basis and additions made to the main list as appropriate.
