Ingredients/Ingrédients: Aqua/Water/Eau ●
TL;DR. This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It dissolves polar ingredients, sets product viscosity, and often forms the continuous phase in lotions, gels, cleansers, and sprays.
What does Ingredients/Ingrédients: Aqua/Water/Eau do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It dissolves polar ingredients, sets product viscosity, and often forms the continuous phase in lotions, gels, cleansers, and sprays.
Is Ingredients/Ingrédients: Aqua/Water/Eau clean?
This ingredient is broadly accepted in clean-beauty frameworks and is generally well-tolerated. The main quality issue is not the molecule itself, but purification and microbial control in the finished formula.
Is Ingredients/Ingrédients: Aqua/Water/Eau sustainable?
This material is widely available, but responsible sourcing still matters because it is a finite local resource in many regions. Its footprint usually comes from purification, heating, transport weight, and wastewater handling rather than from persistence in the environment.
Is Ingredients/Ingrédients: Aqua/Water/Eau COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, although it does not count toward organic content. From a Green Chemistry view, it is a preferred benign solvent with low persistence concerns, but efficient use and low-energy processing improve the overall profile.
How does Ingredients/Ingrédients: Aqua/Water/Eau work chemically?
The molecule is small, highly polar, and strongly hydrogen-bonding, which makes it an effective medium for salts, acids, bases, humectants, and many botanical extracts. Typical use can range from trace amounts to more than 90% of a formula, and systems containing it generally need preservation plus pH and ion control for stability.
