Organotin Compounds
Potential Uses in Apparel and Footwear Textile Processing
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.

Perfluorinated and Polyfluorinated Chemicals (PFCs) Durable water, oil and stain repellent finishes based on long-chain PFC’s are banned from intentional use. There are two methods of manufacture of PFCs referred to as electrofluorination and telemerisation. PFC’s made by the electrofluorination method have by-products associated with them called perfluoroalkyl sulphonates with the most common being the C8 species Perfluorooctane sulfonate (PFOS). The deliberate use of any PFCs made by electrofluorination with a chain length of C6 or above is not permitted. The detection of any PFxS analogue as where X>6 will trigger a failure [i.e. PFHS and above]. These type of PFCs are typically used in home textiles. PFC’s made by the telemerisation method have by-products associated with them called perfluorocarboxylic acids with the most common being the C8 species perfluorooctanoic acid (PFOA). The deliberate use of any PFCs made by telemerisation with a chain length of C8 or above. ZDHC plans to further restrict the use of PFCs in future revisions and details can be found in the candidate list is not permitted. The detection of any PFxA analogue as where X>8 will trigger a failure [i.e. PFOA and above]. These type of PFCs are typically used in clothing and footwear.
Potential Uses in Apparel and Footwear Textile Processing
PFOA and PFOS may be present as unintended by-products in long-chain commercial water, oil and stain repellent agents. PFOA also may be in use for polymers like polytetrafluoroethylene (PTFE).

Phthalates – including all other esters of ortho-phthalic acid
Potential Uses in Apparel and Footwear Textile Processing
Esters of ortho-phthalic acid (phthalates) are a class of organic compounds commonly added to plastics to increase flexibility. They sometimes are used to facilitate moulding of plastic by decreasing its melting temperature. Phthalates can be found in:
- Flexible plastic components (e.g. PVC)
- Print pastes
- Adhesives
- Plastic buttons
- Plastic sleevings
- Polymeric coatings

Total Heavy Metals Listed metals are banned from intentional use in textile manufacturing/finishing unless stated differently. Additionally, residual traces of zinc, iron, and manganese in colourants are expected to comply with the Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers (ETAD) concentration limits (http://www.etad.com/).
The total heavy metal limits do not apply to products containing a listed metal as an inherent compositional part (e.g. metal-complex colorants, the double salts of certain cationic colorant or extenders like barium sulfate). In these cases the extractable content of the corresponding metal has to be considered. Alternatively, the total content will be communicated to the customers, who will determine whether their final product will comply with the corresponding RSL(s) requirements.
