Haha, I definately understand your problem extremely well. I'm a Norwegian too, and yes, here is absolutely nothing to be found, apart from very cheap olive oil and rapeseed oil. It is better in Sweden, but not very much. I was looking for swedish coconut oil, thought it maybe would be cheaper than Delfiafett (expensive Norwegian coconut oil), but could not find any hard oils, only butter, like cow's butter, or what it is called. And the liquid oils are way cheaper here than in Sweden. I forgot to check if swedish lye could be cheaper.
But yes, here is nothing to be found nowhere. Only at online stores abroad. Which is almost impossible to buy from since we can not legally shop for more than eqivalent to $44 (350 NOK) INCLUDED shipping. Otherwise it will be expensive in customs and VAT. And what is $44 dollars when you need like everything? But luckily, some shops do like to cheat and send it in a private name and write "Happy birthday" or something on the parcel, and send the invoice by e-mail.
I have seen somthing like lard or lard-ish. But I can't find it anymore. It was called Smult. Now they have only Flott Matfett. But if I don't remember wrong, Smult was lard or tallow (I don't know the difference).
By the way, I think Flott Matfett is quite good. It contains shea fat, coconut fat and rapeseed oil. I think shea fat is the same as or almost the same as shea butter, just in a cheaper and industrial quality, maybe? Not that Flott Matfett is cheap, but anyway, since we have nothing else, and it is cheaper than Delfiafett. I think I will write to them and ask about the percentages of each fat (it's not said on the package), so that lye can be calculated. And I will let you know if I find out.
I tried to find stearic acid. Of course impossible. So I bought a candle instead
It said 100% stearin on the package. So I just melted it and used it. I had to throw the soap away anyway, it was a disaster like no other! Not the candle, but everything else in the soap.
