Question 1

What does INGREDIENTS/INGRÉDIENTS: Water/Eau/Aqua do in a cosmetic formula?

Accepted Answer

This ingredient is the primary solvent and diluent in most beauty and personal care formulas, dissolving water-soluble actives, salts, humectants, preservatives, and thickeners. It also sets the product’s texture, spread, and concentration of other ingredients.

Question 2

Is INGREDIENTS/INGRÉDIENTS: Water/Eau/Aqua clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is well-tolerated and unproblematic, with no meaningful allergen or restricted-list concern. Quality matters, so cosmetic-grade material is typically purified to control minerals, microbes, and trace contaminants.

Question 3

Is INGREDIENTS/INGRÉDIENTS: Water/Eau/Aqua sustainable?

Accepted Answer

This ingredient is sourced from municipal, purified, or deionized supply streams and has no persistence or bioaccumulation concern. The main sustainability issue is resource stewardship, especially purification energy and use in water-stressed regions.

Question 4

Is INGREDIENTS/INGRÉDIENTS: Water/Eau/Aqua COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards, though it does not count as organic content. It aligns well with Green Chemistry as a benign solvent, especially when purification, heating, and wastewater management are handled efficiently.

Question 5

How does INGREDIENTS/INGRÉDIENTS: Water/Eau/Aqua work chemically?

Accepted Answer

The molecule is a small, highly polar compound made of two hydrogens and one oxygen, giving it strong hydrogen-bonding capacity and broad solvency for ionic and polar ingredients. Typical use can range from under 10% in concentrates to more than 90% in lotions, gels, cleansers, and mists, and it requires preservation in formulas that can support microbial growth.
