As an avid sex toy tester. I decided to check and see if WET silk was safe for my silicone toy. I came across this review of the lube and gave it a go myself.

Pros:
Very slippery but didnt take away from my experience
Using lube (vs no lube) made it much more enjoyable
Cleaned off body and toy easily

Cons:
Had a burning sensation at first, I’ll go ahead and blame the ingredient of alcohol for that one.
Contains many ingredients that I don’t nessisarily want near my kitty. Aka: 3rd ingredient: PEG-6
5th ingredient: Propylene Glycol

“pol·y·eth·yl·ene gly·col
noun
noun: polyethylene glycol; noun: PEG; noun: polyethyleneglycol
a synthetic resin made by polymerizing ethylene glycol, in particular any of a series of water-soluble oligomers and polymers used chiefly as solvents or waxes.” Google

“How Toxic is Propylene Glycol

According to the Environmental Working Group, propylene glycol can cause a whole host of problems. It is rated a 3 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, endocrine disruption, and organ system toxicity. 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. It has also been classified as “expected to be toxic or harmful” by Environment Canada.” -http://thegoodhuman.com/2009/03/31/what-is-propylene-glycol-and-why-you-should-avoid-it/

Make your own educated decisions. As this was a one off for the sake of fair review, don’t be overly afraid of it. Take your precautions like maybe not using it forever but live life.

Have fun,
