Buying the correct antifreeze type for my engine

I’m looking to flush and re-fill my cooling system, and I’m struggling to work out exactly what type of coolant I need to buy.

My maintenance book says I need ‘Ethylene glycol-based antifreeze with a corrosion inhibitor’, but when I search online at my local car parts shop, none of their coolants mention ethylene glycol. Instead, they seem to separate them by ‘silicate’ or ‘OAT’. Does anyone know of either of these correspond to the type I need?

If it helps, I’m in England and my car is a Citroen Saxo 1.1 from 2002. I’m looking online at Halfords. They seem to have a lot of choice, but I have no idea which one corresponds to what I need!
