^aStandard uncertainties (u) are u(T) = 0.20 K, u(NaCl) = 1 mmol kg⁻¹, u(urea) = 2 mmol kg⁻¹, u(thiourea) = 2 mmol kg⁻¹ and u(p) = 5 kPa (level of confidence = 0.68). Relative standard uncertainties (u_r) are $u_r(X_1^{\sigma })=\pm 2\text{\%}$, u_r(β^σ) = ±3%, $u_r(\hspace{0.17em}{f}_1^{\sigma }/f_2^{\sigma })=\pm 4\text{\%}$, u_r(Γ_max) = ±5%, u_r(A_min/A^id) = ±5%, u_r(π_cmc) = ±2%, u_r(pC₂₀) = ±3% and u_r(γ_cmc) = ±2%.
