List Aqua/Water/Eau ●
TL;DR. This ingredient is the primary solvent, diluent, and phase carrier in many formulas, helping dissolve compatible ingredients and set product viscosity and feel.
What does List Aqua/Water/Eau do in a cosmetic formula?
This ingredient is the primary solvent, diluent, and phase carrier in many formulas, helping dissolve compatible ingredients and set product viscosity and feel.
Is List Aqua/Water/Eau clean?
It is well tolerated, non-sensitizing, and not a restricted-it concern in clean-beauty frameworks. The main quality issue is purity, so cosmetic-grade material is typically filtered, deionized, or otherwise treated before use.
Is List Aqua/Water/Eau sustainable?
It comes from local supply systems and its footprint depends mainly on purification, transport, heating, and facility use. It is not a persistence or bioaccumulation concern, but responsible use matters in regions with supply stress.
Is List Aqua/Water/Eau COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, though it does not count toward organic content percentages. From a Green Chemistry perspective, it is a benign solvent with low intrinsic concern, with the main considerations being treatment energy and conservation.
How does List Aqua/Water/Eau work chemically?
It is a small, highly polar molecule with strong hydrogen-bonding capacity, which is why it supports dissolution of salts, glycols, acids, bases, and many botanical extracts. Typical use can range from a minor processing aid to 60 to 95% of a formula, and systems containing it usually need preservation because it supports microbial growth.
