Pure Water ●
TL;DR. It is the primary solvent and diluent in most beauty formulas, dissolving salts, humectants, actives, gums, and preservatives while setting product texture and concentration.
What does Pure Water do in a cosmetic formula?
It is the primary solvent and diluent in most beauty formulas, dissolving salts, humectants, actives, gums, and preservatives while setting product texture and concentration.
Is Pure Water clean?
From a clean-beauty perspective, this ingredient is well-tolerated, non-sensitizing, and not a restricted-list concern. Quality matters, so brands typically use purified grades to control microbes, minerals, and trace contaminants.
Is Pure Water sustainable?
Its sustainability profile depends on local resource use, purification energy, and manufacturing efficiency rather than persistence or bioaccumulation. It can represent a large share of rinse-off and leave-on formulas, so responsible sourcing and wastewater management matter at scale.
Is Pure Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, although it does not count as organic content. It aligns well with Green Chemistry as a benign solvent when purification, heating, and transport impacts are managed efficiently.
How does Pure Water work chemically?
The molecule is small, highly polar, and bent, with strong hydrogen-bonding behavior that makes it an effective medium for ionic and polar materials. Typical use can range from a minor processing aid to more than 90% of a formula, and its microbiological quality must be controlled because it can support microbial growth in preserved products.
