Water [1][2][4] ●
TL;DR. This ingredient is the primary solvent and diluent in many formulas, dissolving or dispersing humectants, surfactants, preservatives, gums, and actives. It also sets texture, spread, and viscosity in emulsions, gels, cleansers, sprays, and toners.
What does Water [1][2][4] do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many formulas, dissolving or dispersing humectants, surfactants, preservatives, gums, and actives. It also sets texture, spread, and viscosity in emulsions, gels, cleansers, sprays, and toners.
Is Water [1][2][4] clean?
Clean-beauty frameworks generally treat this ingredient as baseline and unrestricted when purified to cosmetic quality. Sensitivity is not usually an issue, but formula safety still depends on preservation and overall composition.
Is Water [1][2][4] sustainable?
This material is usually drawn from municipal or purified supply streams, with footprint tied mainly to purification, heating, transport, and effluent treatment. Biodegradability is not the relevant lens because it re-enters natural cycles rather than persisting as an organic pollutant.
Is Water [1][2][4] COSMOS-approved?
This ingredient is permitted under COSMOS-natural and COSMOS-organic standards, though it is not counted as organic content. It fits Green Chemistry well as a benign solvent and processing medium, with best alignment when purification and heating energy are minimized.
How does Water [1][2][4] work chemically?
The molecule is small, polar, and strongly hydrogen-bonding, which makes it effective at dissolving salts, polyols, some acids, and many charged or polar cosmetic materials. Typical use ranges from about 20 to 90% in emulsions, gels, sprays, and cleansers, and it is chemically stable across normal cosmetic pH ranges.
