Silicone Gun Socks...do they hurt non-wood stocks?

I began using these on my rifles from the advice of a friend. They work very well to protect the firearms from being bumped around as I get stuff out of my safe. From a previous life, I know certain oils can degrade certain plastics so I was curious if there are any issues with using these silicone oiled gun socks on guns which have synthetic grips/stocks, composite stocks, fiberglass stocks, or any other stock materials which may be out there?

Thanks!
