What about petrolatum?

        I have discovered an hair oil which it seems to be really good, but after doing some searches on the internet, I discovered that this oil has petrolatum in its composition. Well, a lot of websites are saying that the petrolatum (mineral oil) is a danger to our health. According to some articles, the petrolatum can be one of the causes of some kind of cancers and its use can result in a pneumonia. 
        After read all these things, I'm worried about its use. I don't know if it's good to continue to use this oil.
        The strangest is that the petrolatum is used in the majority of beauty products even in the most famous marks. I don't know if it's true everything that I read on these websites. I know that the use of petrolatum in cosmetics is controlled by FDA, ANVISA and other international organizations, but this is a warranty?
        A lot of these cosmetics which have mineral oil are really good, but my biggest problem is about their consequences for our health. Some people say that mineral oil is really good and its results are good, but on the other hand, some people also tell its routine use can be a danger.

Unfortunately, beauty must be a danger
