Is baby oil safe to use as a lubricant?

No! Oil based lubricants can break down the latex causing them to break. So, if your truly trying to be safe with a condom use a water based lube. From what I read you can use baby oil as a lube, but it's not the most recommend oil to use.

We use vegetable-based oils like cocoa & shea butters because many water-based formulations are just too sticky and require too many reapplications.
