Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
No Canadian affiliation. An affiliation-only frame — the usual design — would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract
The cloud point temperature, T c , of commercial nonionic surfactants: poly(oxyethylene) alkyl ethers (case: dodecan‐1ol polyethoxylate, with the middle chemical structure n ‐C 12 E 6 ) was predicted by applying the Flory–Huggins theory for polymer solutions, adapted to alcohol ethoxylates aqueous solutions by Rupert and using the pseudo‐phase model original developed for micro‐emulsions diagrams composition. The variations of interaction enthalpy as a function of carbon chain length and number of ethylene oxide units are also modelled. The expression of T c as the function of the composition was derived assuming the regular solution for mixed micelles. The experimental results of the cloud point obtained for mixtures of n ‐C 12 E 6 was better reproduced by the pseudo‐phase model, which requires more specific surfactant data (the critical micelles concentration, cmc; critical temperature T C ), and a minimum of experimental data.
