Pure Water/Aqua ●
TL;DR. This ingredient is the primary solvent and diluent in many beauty and personal care products. It dissolves polar raw materials, sets product viscosity, and forms the continuous phase in most emulsions, gels, cleansers, and mists.
What does Pure Water/Aqua do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many beauty and personal care products. It dissolves polar raw materials, sets product viscosity, and forms the continuous phase in most emulsions, gels, cleansers, and mists.
Is Pure Water/Aqua clean?
This ingredient is broadly accepted across clean-beauty frameworks and is generally well tolerated, with no meaningful restricted-list friction. The main quality issue is microbiological control, so formulas that contain it need appropriate preservation and manufacturing hygiene.
Is Pure Water/Aqua sustainable?
It is typically sourced locally and purified by filtration, deionization, distillation, UV, or reverse osmosis. Biodegradability is not a meaningful metric for this simple inorganic solvent, so the sustainability profile depends mainly on use volume, purification energy, and local scarcity.
Is Pure Water/Aqua COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, though it does not count toward organic content. From a Green Chemistry view, it is a benign solvent choice, with the main considerations being purification energy, conservation, and effluent management.
How does Pure Water/Aqua work chemically?
It is a small polar molecule with extensive hydrogen bonding, a high dielectric constant, and strong ability to dissolve salts and many polar raw materials. It commonly makes up 50 to 95% of lotions, gels, shampoos, and cleansers, requires preservative support when present in appreciable amounts, and is compatible across broad cosmetic pH ranges.
