It represents an production average based on the year 2011. The inventory is mainly based on industry data and is completed, where necessary, by secondary data. This data set is based on primary data from European adopted production processes, connected with regional precursor chains. The data set is based on primary production data for quaternized triethanolamine production is from four different suppliers, either France, Germany and Spain, representing the imported and produced quaternized triethanolamine in Europe. Transportation was just considered for the main materials (covers about 90% of the mass of all inputs), other transportation was not considered.83Primary production data for TEA-Quat production is from four different suppliers in Europe in three different countries (France, Germany and Spain).Foreground system: Quaternized triethanolamine fatty acid esters are obtained by reacting triethanolamine with fatty alcohols, fatty alcohol esters or oils and subsequent quaternization of the resulting triethanolamine fatty acid esters. The fatty acid used is tallow fatty acid. Dimethyl sulphate (DMS) is the quaternizing agent. To the esteramine, isopropanol is added as a solvent to lower the viscosity of the reaction mixture. The quaternization is carried out by slowly add-ing dimethyl sulphate in several portions at temperatures between 40 and 60°C. A slightly under-stoichiometric amount of dimethyl sulhate is used to ensure that all of the toxic di-methyl sulphate can react with esteramine, and thus avoiding traces of dimethyl sulphate in the end product. [ZOLLER 2009] The product is a mixture of quaternized mono-, di- and tri-esters of triethanolamine and unconverted triethanolamine, which corresponds to the so called quaternized triethanolamine di(tallow)fatty acid ester.
Background system:
Electricity: Electricity is modelled according to the individual country-specific situations. The country-specific modelling is achieved on multiple levels. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. due to pumped storage hydro power etc.), as well as imported electricity. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. element and energy content) are accounted for. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. different crude oil production technologies or different flaring rates at the oil platforms.
Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. The thermal energy and process steam are produced at heat plants. Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. For process steam the efficiency ranges from 85%, 90% to 95%. The energy carriers used for the generation of thermal energy and process steam are modelled according to the specific import situation (see electricity above).
Transports: All relevant and known transport processes are included. Ocean-going and inland ship transport as well as rail, truck and pipeline transport of bulk commodities are considered.
Energy carriers: The energy carriers are modelled according to the specific supply situation (see electricity above).
Refinery products: Diesel fuel, gasoline, technical gases, fuel oils, lubricants and residues such as bitumen are modelled with a parameterised country-specific refinery model. The refinery model represents the current national standard in refining techniques (e.g. emission level, internal energy consumption, etc.) as well as the individual country-specific product output spectrum, which can be quite different from country to country. The supply of crude oil is modelled, again, according to the country-specific situation with the respective properties of the resources.Triethanolamine Esterquats (TEA-Quat) is a cationic surfactant that belongs to the class of surface active quaternary ammonium compounds.ERASM_Triethanolamine Esterquats (TEA-Quat ).JPGLCI resultAttributionalNoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massNot applicableFOREGROUND system: No allocation was applied in the production processes.
Background system: For the combined heat and power production, allocation by exergetic content is applied. For the electricity generation and by-products, e.g. gypsum, allocation by market value is applied due to no common physical properties. Within the refinery allocation by net calorific value and mass is used. For the combined crude oil, natural gas and natural gas liquids production allocation by net calorific value is applied.

PackagingNoneSeveral data sources have been averaged. Average values are the ones used in the inventory. Whenever intermediates may constitute a reasonable sub-system boundary, a hybrid of vertical and horizontal averages were used. Data for the production of quaternized triethanolamine at the production sites in France, Germany and Spain of the different companies, that are member of the ERASM associacion, was collected by data questionnaires. Data was subsequently verified in telephone conferences and meetings with specialist staff from the companies. Some surfactants and precursors are produced as solution e.g. x% active ingredient matter solved in water. This fact is reflected in the declared unit, which is defined on the basis of active ingredient matter or chosen precursors and intermediates. To level the different concentrations resulting based on company specific production figures, a concentration scheme with the goal to present every LCI for 1000kg of surfactant at 100% active ingredient level or chosen precursors and intermediates was applied. In case of the present surfactant, the data was levelled out to give 1000 kg of product with a concentration of 90.0%.The GaBi 6 software system was used for generating the model of the production and as the source of background LCA information. The average environmental burdens of the national power grid mix in the production countries are used in the model. In case of steam or energy supply at the production site, the data is based on the GaBi data base. Data sets for the quaternized triethanolamine production as main input material and auxiliary materials as e.g. water were also taken from the GaBi data base.No SOM method landuse included as the SOM method is not used elsewere in the GaBi database.Data was collected and treated to ensure the resulting inventory is representative for the average European Triethanolamine Esterquats (TEA-Quat) . Namely, the data was collected from 4 producing companies and covers > 70% of the European Triethanolamine Esterquats (TEA-Quat) production. Data collection period: one year production. The datset is representative for the state of technology in 2011. The datasets are considered to be valid until substantial technological changes in the production chain occur.NoneERASM Surfactant Life Cycle and Ecofootprinting (SLE) ProjectGaBi databases70.02012-2014NoneThe dataset covers cradle-to-gate system of C16-18 TEA-Quat production.

This cradle-to-gate LCI includes assimilated carbon dioxide also referring to carbon uptake due to the renewable feedstock. The assimilated carbon dioxide corresponds to the input flow "Carbon Dioxide [Renewable Ressources]". In case this LCI is used in cradle to grave assessments the incorporated carbon dioxide should be modeled as release to environment during the use and/ or end of life stage in addition to other use and/ or end of life treatment emissions.All relevant flows quantifiedThe LCI method applied is in compliance with ISO 14040 and 14044. The documentation includes all relevant information in view of the data quality and scope of the application of the respective LCI result / data set. The dataset represents the state-of-the-art in view of the referenced functional unit.
Prof. Dr. Walter KlöpfferCharlotte PetiotTwo independent external reviewers, focusing on the LCA methodology conformity and the technology representativeness respectively, supported the project from the beginning till completion. This approach ensures traceability and quality of the results.
Both reviewers check all reports and relevant decisions which the group might take to as-sure consistency and conformity to standards. They also participate on project meetings to follow the projects progress.
The critical review is performed according to the ISO 14040 (chapter 7.3.2) [ISO 14040: 2006 ] and ISO 14044 (chapter 6.1) [ISO 14044: 2006 ] standards.
In addition the oil palm and coconut based renewable precursors are reviewed by a third independent external expert, who is familiar which such products in particular and an ex-pert in the field of evaluating land use and land use change emissions.
