Non irritating to rhe skin [SEP] This particuar order smelled "off." I've used this stuff for years, and this last bottle came with a peculiar rancid smell. I'm going to blame it on the age of the product or the storage of it before it came to me.  Normally, Nutribiotic is a great product with a pleasant light fragrance. It does not irritate my skin, and rinses away easily without drying out the skin. So, I hope this last batch was a fluke.
