While it lathers well and smells great, I'm not happy with the appearance. So I tried the second time. This time I did not mix the milk and the lye but I added the milk latter after the soap had gelled.
I added the milk little by little. Eventhough the soap was quite hot, it did not burn the milk .
The oils I used for this liquid soap were coconut oil, palm oil, olive oil, sunflower oil dan cocoa butter. It"s quite thick so I call it shower gel. I was pretty happy with the result :)
