I am curious if anyone can tell me what these streaks are in my soap? I am thinking it is stearic acid from palm oil I didn't heat well enough. Seems to be through out the whole batch. I use Coconut Oil, Olive Oil. Palm Oil, Avocado Oil and Castor Oil. I soaped at closer to room temp this time (70-80_ range as opposed to close to 110-120) like prior batches, mainly because my lye water cooled super fast and I wasn't sure if I could warm it in the microwave, so I just went with cooler oils. Is this just a cosmetic flaw? Is it safe to use? This was superfatted at 8% There are not fragrances or colorants this was a plain batch to test my recipe.
