I bought this from Cousins which was advertised as Silicone grease. Immediately I noticed that it smelled a bit like dubbin (animal fat) and also a bit like shoe polish. The colour is also amber.  I heated a blob of it and it immediately melted and ignited, and when I distinguished it, it continued to leave a white smoke, like a candle.  I told Cousins that I didn't believe that it was Silicone, so they've asked the manufacturer Ho have replied saying that it is indeed silicone grease.
