INCI name:

Aqua is probably one of the most important ingredient used in cosmetic products. It is an odorless, tasteless, inorganic, transparent, and nearly colorless substance that occurs naturally on the Earth’s surface. If the list of ingredients shows Aqua on the top - it almost definitely means that Aqua ingredient is present in more quantity than any other ingredient in the product. Based on the category, Water makes up almost 60-85% of the product. It may even go up to 95% in rinse-off products like shower gels and shampoos.

Aqua occurs naturally on the earth’s surface and is made by two hydrogen atoms and one oxygen atom joining together to form a molecule (H2O). In cosmetics products, only distilled or deionized water is used, which is a highly purified variant of water.
