This is what mouldy cream looks like:
Ewwwww.
Well we've had a heatwave recently, and I didn't keep the creams in the fridge, so the Fruity blend cream got mouldy, as did what was left of the main batch of the Forest blend, which I also kept in my room. But the main batch of the Fruity blend is in the fridge, and at the last check there was no sign of mould.
Now the weird thing is, the first ever cream I made, you remember the main batch went mouldy? But I had decanted some into an old cleaned out lip balm tub and kept that in my bag to use at work. Well, I still have that same cream in there and it is not mouldy. That is so weird.
Anyway, shelf life of the creams is about 3 months, and that was with not putting in enough potassium sorbate. I made that last batch in March, and it went off end of June/beginning of July. So that's not too bad.
It's a weird thing though, I made a new batch last weekend, but for some reason the cream is not thickening like it did the first time. That one was a very thick, creamy cream. This time it's a runny lotion, which I don't like as much. And I used the same proportion of water (6 parts) as I did the first time. Weird. Maybe using more EOs does it, or perhaps the citric acid and p. sorbate? No idea.
Also, lesson learned: grapefruit essential oil is way too drying. Leave it out unless you have really greasy skin.
The real takeaway from this is that you should always store these in the fridge.
