I made a soap last July, that by December had lost its scent. By January it had discoloured in the white portions to a caramel-brown colour and smelt a bit oily. Like cooking oil kinda smell. I've kept the remaining bars and today I noticed they were all 'sweaty' and oily on the surface. It smells like a wood oil, not a fragranced soap. Not pleasant but not rancid smelling.
Looking back at the recipe - I went through a phase of using 10% avocado oil, of which this batch of soap was one, so I checked all my soaps made with that recipe and don't recall having any problems with those, but I only have one of those other fragrances left of the 5 or so batches I made at that time. So I think I've satisfied myself that its not the additional avocado oil. Unless anyone can cite any issues they've had with 10% avocado oil?
The next option is the FO - which was Sugar Plum - think possibly from Nature's Garden but not 100% since my supplier here can be a bit vague about where it's from. I also added a bit of Sweet Orange EO - which I use in a lot of my soap with no problem.
All other ingredients in the soap were as per normal, so there was nothing untoward about them - my soaps usually last well over the 10 month mark without this kind of thing happening. I cut all the outside of one of the bars off, and the browny colour goes all the way though, but the soap still performs well. Just smells like I've washed my hands with cooking oil is all.
Anyway - have a look a see if any of you can come up with any reason why this might have happened?
