bAwear does not calculate chemical toxicity because the composition and behaviour of chemicals used in textile processes are largely unknown and highly variable. Chemicals in formulations are often not fully disclosed, and their reactions and transformations during processing are complex and unpredictable. Safety Data Sheets (SDS) are frequently incomplete, making it difficult to assess toxicity accurately. Additionally, eco-toxicity models require known chemical structures, which are not always available. Consequently, bAwear believes that any toxicity impact calculations would be unreliable, and potentially misleading by a factor of 10-100 times, and thus prefers not to report these impact categories.
