INGREDIENTS/INGRÉDIENTS: Water ●
TL;DR. This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It forms the continuous phase for gels, lotions, cleansers, mists, and serums, helping dissolve salts, humectants, preservatives, and other polar materials.
What does INGREDIENTS/INGRÉDIENTS: Water do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It forms the continuous phase for gels, lotions, cleansers, mists, and serums, helping dissolve salts, humectants, preservatives, and other polar materials.
Is INGREDIENTS/INGRÉDIENTS: Water clean?
From a clean beauty perspective, it is well-tolerated and unproblematic when properly purified and preserved in finished formulas. The main formulation issue is not the ingredient itself, but microbial control in products that contain high levels of it.
Is INGREDIENTS/INGRÉDIENTS: Water sustainable?
Its footprint is mainly tied to purification, heating, transport, and effluent management rather than persistence or bioaccumulation. Responsible manufacturing focuses on conservation, closed-loop processing, and efficient cleaning systems.
Is INGREDIENTS/INGRÉDIENTS: Water COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic products, although it does not count as organic content in the certification calculation. It aligns well with Green Chemistry as a benign solvent, with the main caveat being energy use for purification and processing.
How does INGREDIENTS/INGRÉDIENTS: Water work chemically?
The molecule is small, bent, and highly polar, with extensive hydrogen bonding that gives it strong solvent power for ions and many polar compounds. It commonly makes up 50 to 90% of emulsions, gels, cleansers, and sprays, and it requires an appropriate preservative system when present at high levels.
