Mind Boggled

[greenteapirate.livejournal.com]

I recently made a body balm that is growing mold. It contains cocoa butter, shea butter, jojoba oil, lecithin, and water. What could possibly cause it to mold a month after I made it? The lecithin is really pretty old but would it actually mold when mixed into lotion? All of the other ingredients are brand new. I am so...sad and confused.

Also, is beeswax used as just a thickener or is it also an emulsifier? Or does it have some other purpose of which I am unaware?

Thank you!
