Yes, it is silicone (some people shouldn’t be able to review products until they take a class or something). If you know the difference between different types of lubes and you are looking for a good silicone lube, this is it. Nice and silky smooth, not too thick, cleans up easily with a little soap and water and it’s fantastic for use in the shower. Obviously, make sure that you don’t use it with things that don’t like silicone lubes and you will enjoy it!
