I wanted to share my observation, along with some thoughts on the recipe itself.
From what I understand, there are 3 main soybean products used in soaping (at least those 3 are present in SMF).
The first one is the regular soybean oil, which is high in linoleic acid. If the recipe has this one with that high %, the soap would be very prone to DOS unless you use the right combo of chelator/antioxidant. That % of soybean oil could normally also result in a softer bar of soap, but in this particular case with that % of saturated fats that shouldn't be the case. Overall, it won't be a great recipe by itself, but with the correct additives it could be fine.
The second one is the partially hydrogenated one which is high in oleic acid (I think that is the same as what AliOop refers to as the high oleic soybean oil variety used in high temp cooking, but I may be wrong). If this is the one used in the recipe, I think that would make the most balanced option, closer to the usual soap trinity PO/CO/OO and it will give you both really good soap qualities and enough saturated/unsaturated ratio for the recipe to be easily workable under the right conditions. In theory that should result in a hard bar of soap with good lather, not too harsh on the skin. This would be the best option IMO, if it's present. I think you mentioned you found soybean oil labeled as 'high smoke point' - to make sure it's the right one, check the label ‐ monounsaturated fatty acids should make the majority of its content for it to be the high oleic type, If that's the case - I say go for it, the soap made with it will be (in theory) similar to one made with olive oil).
Now the third one is what is referred to as soy wax and it's fully hydrogenated. It makes a hard soap bar because it has lots of stearic acid in it. If that's what they want used in the recipe (which I doubt, since it would otherwise be listed as soy wax or hydrogenated soybean oil, not as soy oil only ‐ but you also mentioned language barrier here, so I'm not exactly sure what they want in the soap), that would make a really hard bar of soap with plenty of saturated fatty acids (all fats are solid after all), which could be a little tricky to work with since the batter will trace fast. While it would make a fine enough soap, I don't see a reason why you wouldn't put some liquid oil in it, for balance and for convenience. Overall, the second option is the best to me, which is great since you probably have the high oleic liquid type available to you.
HTH and sorry for the long post
