The base of almost all our formulations, ‘aqua’ is the INCI name for purified water.
INCI stands for International Nomenclature of Cosmetic Ingredients, which is an international system of unique names for chemicals and other personal care ingredients, based on scientific names and other Latin and English words.
We use water in just about all of our products as a solvent - helping dissolve and distribute other ingredients that have functions like conditioning or cleansing.
Other names: H2O, Water
