I have a bottle of moisturizer that is pretty expensive and it is in a black bottle. It is 50ml, I was wondering if I can bring that on my carry on because I saw on a website saying that liquids in opaque or metal containers or containers that cannot be easily scanned will be thrown away. I dont want to throw away that bottle of moisturizer and I am not checking baggage. This is what the moisturizer looks like: http://www.scform.com/wp-content/uploads/2012/05/labseriesbb.jpg

Also, how many 100ML bottles can you bring if it is in a one quart bag?
