Question 1

What does AQUA / WATER / EAU. [+/- MAY CONTAIN / PEUT CONTENIR CI 77491 do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as the solvent and diluent in beauty products, creating the liquid phase that dissolves, disperses, or carries other ingredients. It also helps set texture, spread, and concentration.

Question 2

Is AQUA / WATER / EAU. [+/- MAY CONTAIN / PEUT CONTENIR CI 77491 clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is well-tolerated and broadly unproblematic. The optional pigment notation in the heading is typically a permitted mineral colorant when purity specifications for trace metals are met.

Question 3

Is AQUA / WATER / EAU. [+/- MAY CONTAIN / PEUT CONTENIR CI 77491 sustainable?

Accepted Answer

This material is abundant, non-persistent, and not a biodegradation concern, but its footprint depends on purification, heating, transport, and responsible use in manufacturing. The optional mineral pigment component is inert and mined, so supply-chain attention centers on purity controls and sourcing practices.

Question 4

Is AQUA / WATER / EAU. [+/- MAY CONTAIN / PEUT CONTENIR CI 77491 COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards, although it is not counted as organic content. It fits Green Chemistry principles as a benign solvent with low reactivity, with the main considerations being conservation and energy used for purification.

Question 5

How does AQUA / WATER / EAU. [+/- MAY CONTAIN / PEUT CONTENIR CI 77491 work chemically?

Accepted Answer

The molecule is a small, highly polar, hydrogen-bonding compound with a high dielectric constant, which makes it effective at dissolving salts, acids, bases, and many polar actives. It is commonly the largest phase in emulsions, gels, cleansers, and sprays, and formulators control microbial quality, pH, and electrolyte load because it strongly affects viscosity, preservation, and stability.
