If I were you, I'd try adding some essential oil to it and see if that doesn't cover of the smell. Essential oil is alot stronger than regular fragrance oil, so don't add more than 1 teaspoon per pound (or 2 teaspoons per kilo). If you let melt and pour base get too hot for example boil, it will ruin the base.
Another thing you can do is just contact the company directly and ask why this is happening. I noticed there is a "Fale conosco" button that gives you some email addresses, send an email to the Qualidade department.
Unfortunately, I don't know what else to tell you, since I haven't had that much experience, and the bases I buy haven't had any alcohol smell. Hope this helps a little.
I was trying to get some info before calling them.
The base has been warmed up no more than 80° celsius (below boiling point) , we stirred it for some time at this temperature in order to get rid of the alcool, the soap came out nice and smooth BUT lost its transparence :?
Now I've read that clear soap can be produced with different kinds of alcool the usual one or sorbitol like the one you refered to in your advice.
