Purified Water ●
TL;DR. This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It dissolves polar ingredients, helps set viscosity, and forms the continuous phase for gels, lotions, cleansers, and sprays.
What does Purified Water do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It dissolves polar ingredients, helps set viscosity, and forms the continuous phase for gels, lotions, cleansers, and sprays.
Is Purified Water clean?
From a clean-beauty perspective, it is well-tolerated and broadly unproblematic. The main quality issue is purity, since minerals, microbes, and processing residues must be controlled through proper purification and preservation of the finished formula.
Is Purified Water sustainable?
This material is typically sourced from treated municipal or natural supplies, then it by filtration, distillation, deionization, or reverse osmosis. Its footprint is mainly tied to purification energy, heating during manufacturing, and transport rather than persistence as a synthetic pollutant.
Is Purified Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, although it does not count toward organic content. It aligns well with Green Chemistry as a benign solvent, with the main caveat being energy use for purification and processing.
How does Purified Water work chemically?
The molecule is small, polar, and strongly hydrogen-bonding, which makes it an effective carrier for salts, humectants, acids, bases, and many botanical extracts. It often makes up 50 to 90% of emulsions, gels, and cleansers, has a neutral pH near 7 before formulation adjustment, and requires a suitable preservation system once nutrients or plant-derived materials are present.
