Not enough to make the foam

Contrary to what one might think it is not natural, one realizes when one reads its composition (too late if purchased): propylene glycol, and others in the genre ... so buy a good bomb foam just as chemical and cheaper
for the same effect. When the smell ... you have to love ... not sure whether it is essential to flavor this kind of product.
In addition, the product arrived outdated.
A product that I recommend.
