I recently ordered a new jar of MdC and I noticed a couple of changes between one I ordered about three years ago to today's. It now has 200g vs 170g, the jar I received is plastic and not glass, and the formula now has sodium chloride. The one thing I'm disappointed in is the plastic jar. Their web site says it comes in a "glass pot". I emailed them today asking how to get a glass jar next time--if that's possible, and that their plastic jar is missing that je ne sais quoi. It will be interesting to see if they answer the email.
