effects of propylene glycol (wintergreen base solution)

[Lucy]

I'm getting ready to mix up grease patties and I notice my wintergreen extract is mixed with propylene glycol. Will this harm my bees?

I wonder what happen it ends up in honey? That's what I found on the internet.

How Toxic is Propylene Glycol

According to the Environmental Working Group, propylene glycol can cause a whole host of problems. It is rated a 4 by them, which is categorized as a “moderate” health issue. It has been shown to be linked to cancer, developmental/reproductive issues, allergies/immunotoxicity, neurotoxicity and endocrine disruption. It has been found to provoke skin irritation and sensitization in humans as low as 2% concentration, while the industry review panel recommends cosmetics can contain up to 50% of the substance.

I don't think it will harm your bees but not sure what other effect it will have. It's my opinion that treating mites always has some effect on the bees. It's a matter of what your tolerance is and what the end result is for the colony. That formula is not always simple!

Lucy, I don't know the answer to your question, but I believe most recipes call for Essential Oils, NOT extracts.

Essential oils extracted with the steam method if I'm not mistaken.
