The textile and leather industry is a sector with high consumption of chemical auxiliaries – from dyes and surfactants to finishing agents and tanning chemicals. Each of these raw materials must meet strict safety and health protection requirements defined by the REACH and CLP regulations. Safety Data Sheets (SDS) are the primary tool for communicating risks, but their correct interpretation requires knowledge of the context and legislative requirements. How can you navigate them to minimize risks for employees and the environment while ensuring efficient production?

REACH and CLP: The fundamental framework for the textile and leather industry

The REACH Regulation (Registration, Evaluation, Authorisation and Restriction of Chemicals) and CLP Regulation (Classification, Labelling and Packaging) form the fundamental legislative pillars for the management of chemical substances in the European Union, including auxiliary chemicals used in the textile and leather industries. REACH focuses on the registration, evaluation, and potential restriction of substances, while CLP sets out the rules for their classification, labelling, and packaging according to the GHS (Globally Harmonized System). For manufacturers and processors in the textile and leather sectors, it is crucial to understand how these regulations affect the selection and use of auxiliary chemicals such as dyes, surfactants, softeners, or surface treatment agents.

In practice, this means that every substance or mixture supplied to the EU market must be registered under REACH if its annual volume exceeds 1 tonne. Manufacturers and importers are obliged to provide data on the properties of the substances, their safe use, and potential risks. CLP then ensures consistent labelling of hazardous substances using warning symbols, standardised hazard statements (H-phrases), and safety instructions (P-phrases). For textile and leather industry businesses, it is essential to verify whether chemical suppliers comply with these requirements, particularly for substances on the REACH Candidate List (SVHC – Substances of Very High Concern).

Safety Data Sheets (SDS): How to Read and Interpret Key Information

The Safety Data Sheet (SDS) is a fundamental document that chemical suppliers must provide to their customers. For textile and leather processing operations, it is essential to correctly interpret its individual sections to ensure the safe and effective use of auxiliary chemicals. The SDS contains 16 mandatory sections, the most important of which are the identification of the substance/mixture and supplier (Section 1), hazard information (Section 2), composition (Section 3), first aid measures (Section 4), and fire-fighting measures (Section 5).

For textile and leather applications, Section 9 is particularly important, as it describes the physico-chemical properties of the substance, such as boiling point, solubility, or pH. This data influences, for example, the selection of suitable process conditions for dyeing, washing, or surface treatment. Sections 11 and 12 then provide information on toxicological properties and ecological impacts, which are key for assessing risks to employees and the environment. When working with SDS, it is important to verify that the document is up to date (the issue date should not be older than 5 years) and that it complies with the current requirements of the REACH and CLP regulations.

Practical impacts of REACH and CLP on manufacturing processes in the textile and leather industry

The implementation of REACH and CLP requirements has a direct impact on manufacturing processes in the textile and leather industries. One of the main effects is the need to replace substances that are on the SVHC candidate list or subject to authorization under REACH. This applies, for example, to certain phthalates used as plasticizers in textile coatings or perfluorinated compounds (PFCs) used for hydrophobic treatments. Manufacturers must seek alternative solutions that meet technical requirements while complying with legislation.

Another important aspect is the proper labeling and storage of chemicals according to CLP. Warning symbols and H-statements must be clearly visible on packaging and in the workplace to inform employees about potential risks. For example, substances labeled with the corrosive effect symbol (GHS05) require special protective equipment and storage conditions. Processes such as dyeing, printing, or textile surface treatment must be adapted to minimize employee exposure and emissions into the environment. This may include the use of closed systems, local exhaust ventilation, or replacing hazardous substances with less risky alternatives.

How to ensure compliance with legislation and minimize risks

For textile and leather companies, it is crucial to implement a systematic approach to chemical risk management. The first step is to create an internal list of all chemicals used, including their safety data sheets. This list should be regularly updated and verified against the REACH registered substances database and the SVHC candidate list. Furthermore, it is necessary to conduct employee training focused on the proper handling of chemicals, reading safety data sheets, and using protective equipment.

An important part of compliance is also cooperation with suppliers. Companies should require their suppliers to confirm compliance with REACH and CLP regulations and regularly verify the up-to-dateness of provided safety data sheets. In case of doubts about the safety of a particular substance, it is advisable to consult a chemical safety expert or use the services of accredited laboratories for testing chemical properties. To minimize risks, it is also possible to implement an environmental management system according to applicable standards, which helps identify and manage potential impacts on the environment and employee health.

Critical points in safety data sheets for textile and leather chemicals

Safety Data Sheets (SDS) for auxiliary chemicals in the textile and leather industries contain specific information that must be carefully evaluated. A key section is Section 2 (Hazard Identification), which provides the classification of the substance according to the CLP Regulation. For textile and leather applications, data on skin irritation, sensitization, or acute inhalation toxicity are particularly important. These properties can affect not only worker safety but also the final quality of the product, such as children's clothing or leather goods intended for direct skin contact.

Another critical section is Section 11 (Toxicological Information), which details the effects of the substance on human health. For textile and leather chemicals, such as dyes, finishes, or leather processing agents, attention must be paid to data on potential carcinogenic, mutagenic, or reprotoxic properties. This information is essential for assessing long-term risks and for deciding whether a substance is suitable for a specific application. It is always necessary to compare this data with the requirements for the final product, such as the Ecological Textile Regulation or safety standards for children's products.

REACH Registration and Its Impact on the Availability of Textile and Leather Chemicals

The REACH Regulation significantly influences the availability of chemical substances on the European market, which has a direct impact on the textile and leather industries. Substances that have not been registered under REACH may not be manufactured or imported into the EU in quantities exceeding one tonne per year. This can lead to a limited supply of certain specialized chemicals, such as specific types of dyes, softeners, or leather processing agents. Manufacturers and processors of textiles and leather must actively monitor the list of registered substances (REACH database) and adapt their formulations to available alternatives.

For textile and leather processing companies, it is also important to monitor substance evaluation processes and any restrictions under Annex XVII of the REACH Regulation. Some substances that were previously commonly used may be gradually restricted or banned, such as azo dyes, phthalates, or certain perfluorinated compounds (PFCs). Companies should have a plan in place to replace these substances with safer alternatives to avoid production disruptions or supply chain issues. Timely communication with chemical suppliers is key to ensuring production continuity.

Practical Tools for Managing Safety Data Sheets and Regulatory Compliance

Effective management of Safety Data Sheets (SDS) is fundamental to ensuring compliance with REACH and CLP regulations in the textile and leather industries. It is recommended to implement a digital system for archiving and updating SDS, which allows for quick searching and access to the latest versions of documents. Safety data sheets should be regularly reviewed, especially upon receiving an updated version from the supplier, at least once a year. It is also important to ensure that all relevant departments (production, quality, occupational safety) have access to the necessary information and are trained in its interpretation.

To facilitate work with safety data sheets, specialized software tools can be used to automatically check compliance with legislation and alert users to changes in substance classification. These systems often allow for the generation of custom safety data sheets for mixtures used in production, which is particularly useful for textile and leather companies that frequently work with their own formulations. Additionally, it is advisable to establish an internal process for assessing risks associated with the use of chemicals, which includes regular reviews of substances used and their potential replacements. This approach helps minimize risks and ensures the long-term sustainability of production.
