TEGO® SML 20 is a liquid emulsifier that is non-ionic and made of polyoxyethylene-(20)-sorbitan monolaurate. It is used as a solubilizer for oils and dyestuffs, as well as a defoamer and antistatic agent in textile formulations. TEGO® SML 20 is compatible with anionic, cationic, and amphoteric surfactants due to its non-ionic nature. It is also biodegradable and has good environmental behavior. When used as a co-emulsifier, it exhibits synergistic effects with other surfactants.

Functions: Anti-Static Agent, Defoamer, Emulsifier, Solubilizer

Framework of LCA

Goal:

  • Calculation of the environmental performance of products manufactured and sold by Business Line Interface & Performance.

System Boundary:

  • Cradle-to-Gate

Functional Unit (FU):

  • 1 kg TEGO® SML 20

Methodology:

  • All our Life Cycle Assessments are following the principles of ISO 14040/44 and ISO 14067 standards.
  • The established method of the Dutch Environmental Science Research Center Leiden (CML) with characterization factors from November 2013 was used.
  • Data Sources: The LCA was created in 2020 by an internal Life Cycle Management team.
  • The LCA is based on primary data from the year 2014 by Evonik for the production process, while secondary data from databases (such as GaBi and ecoinvent), suppliers or literature is utilized for external processes and raw materials.
  • The software GaBi 10 was used for the LCA modeling.
  • The data for energy consumption were updated with values from 2021.

Cut-off rules for the inventory:

  • In general, 1% for single inputs and below 5% for the sum.
  • No environmentally relevant flows were neglected.
  • Some utilities of production processes have been modeled analog to known processes.
  • Transports have been considered but distances have mainly been estimated.
  • The result uncertainty in all categories is about +/- 20 % as these results base on several assumptions.

Result (Cradle-to-Gate):

Evaluation variables Value Unit per FU
Blue water consumption 90.1 kg
Acidification Potential 0.01 kg SO2 eq.
Global Warming Potential incl. LUC 1.2 kg CO2 eq.
Primary Energy Demand 53.3 MJ
