AEEA fatty acid condensation products belong to the frequently applied active substances which the chemical industry has produced in big quantities for decades and which have been further processed to textile softeners due to the particular advantages in terms of the application properties. Within the framework of the REACH1 registration activities for AEEA fatty acid condensates the potential of toxicity for reproduction was recognised for the whole group of substances through conclusion by analogy to an already registered substance which had been classified as toxic for reproduction and finally ascertained. Substances with a potentially harmful effect on health are grouped under the so-called CMR substances (carcinogenic, mutagenic, toxic for reproduction), and they are subject to legally regulated mandatory labelling. On the basis of new knowledge AEEA fatty acid condensation products (without further derivatisation) have to be labelled according to GHS2 as hazardous substances with "repr. category 1B" and "H 360D" (may cause harm to the unborn child). Although there is no immediate risk for the consumer in case of skin contact in accordance with the exposition and risk assessment, the first producers of textiles auxiliaries stopped production of AEEA fatty acid condensation products and therefore acted extremely responsibly in the interests of "Responsible Care".

Background: The enzymatic desizing of starch-sized cotton fabrics leads to wastewaters with an extremely high chemical oxygen demand due to its high sugar content. Nowadays, these liquors are still disposed without use, resulting in a questionable ecological pollution and high emission charges for cotton finishing manufacturers. Methods: In this paper, an innovative technology for the production of energy from textile wastewaters from cotton desizing was developed. Such desizing liquors were fermented by methane-producing microbes to biogas. For this purpose, a semi-industrial plant with a total volume of more than 500 L was developed and employed over a period of several weeks. Results: The robust and trouble-free system produces high amounts of biogas accompanied by a significant reduction of the COD of more than 85%. With regard to growing standards and costs for wastewater treatment and disposal, the new process can be an attractive alternative for textile finishing enterprises in wastewater management, combining economic and ecological benefits. Conclusion: Moreover, the production of biogas from textile wastewaters can help to overcome the global energy gap within the next decades, especially with respect to the huge dimension of cotton pretreatment and, therefore, huge desizing activities worldwide. © 2012 Opwis et al; licensee Springer.
