I’m seeking help from everyone – does anyone know the thermophysical properties of an ethylene glycol aqueous solution with a volume concentration of 40%? I need this information urgently; thank you very much!

I need this for my graduation project. Does anyone among you know the thermophysical properties of ethylene glycol at a volume concentration of 40%? Thank you all!
It’s like this: I want to find the physical property parameters of an ethylene glycol aqueous solution with a volume concentration of 40% at -4°C. However, the chemical handbook only provides values for integer temperatures, and it doesn’t list a volume concentration of 40%; the only value available is 37.8%. As a result, I can’t find the exact figures. If such information isn’t available in the handbook, should I simply use an approximate value or calculate it myself? For example, is it acceptable to use data on an ethylene glycol aqueous solution with a volume concentration of 37.8% at -5°C in place of data on one with a volume concentration of 40% at -4°C?
Interpolation, right? The simplest form is linear interpolation; for more complex cases, quadratic interpolation is used. If you want to save time, Excel has trend lines available
