Water/Aqua/Eu ●
TL;DR. This ingredient is the primary solvent and diluent in many formulas, helping dissolve salts, humectants, preservatives, some actives, and surfactant systems. It also sets texture, spread, and concentration in emulsions, gels, cleansers, and sprays.
What does Water/Aqua/Eu do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many formulas, helping dissolve salts, humectants, preservatives, some actives, and surfactant systems. It also sets texture, spread, and concentration in emulsions, gels, cleansers, and sprays.
Is Water/Aqua/Eu clean?
From a clean-beauty perspective, this ingredient is well-tolerated, non-sensitizing in normal cosmetic use, and not a restricted-list concern. Quality matters, so brands typically use purified grades to control microbes, minerals, and trace impurities.
Is Water/Aqua/Eu sustainable?
This material is sourced through purification rather than complex synthesis, and it does not bioaccumulate or create persistence concerns in the usual cosmetic sense. Its main sustainability considerations are local resource stewardship, purification energy, heating during manufacturing, and responsible wastewater handling.
Is Water/Aqua/Eu COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic products, although it does not count toward organic content. Its Green Chemistry profile is strong when purification is efficient, with the main impacts coming from energy use and process management rather than the molecule itself.
How does Water/Aqua/Eu work chemically?
The molecule is small, highly polar, and has a high dielectric constant, which makes it effective for dissolving ionic and polar materials while shaping viscosity and phase behavior. Use levels range from trace amounts to 60 to 95% in many lotions, gels, cleansers, and sprays, and formulas containing it generally require a suitable preservation system.
