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

Leaky

Great stuff but found that the tube it comes in punctures really easily so you get ‘leaks’

Do yourself a favour look after connections

This is excellent stuff and much cheaper than OEM products while having exactly the same characteristics. If you’re running a older car this does help minimise electrical issues.
