Alkyl sulphate (c12-14) (alkyl sulphate (C12-14) production)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product alkyl sulphates are nonionic surfactants. This type of product can either have no colour or have a colour that is in between yellow and brown. The main application of surfactants is in the production of cleaning products for both household application and personal care (Kosswig 2000).

Modelling this substance in a solution requires the user to add the solvent of their choice in their models. Reference(s): Kosswig K. 2000. Surfactants.
