Is this silicone based and is it safe to use on plastic?

Have to do a test on small piece of plastic.

Use on lamda sensor thread

Not for use like this, I would use a copper grease only on threads but not the sensor body

What’s the colour of the grease, is it a thick consistency and is it conductive?

It's virtually colourless, it's creamy consistency, not thick at all and,yes, it is electrically conductive
