Water/Aqua ●
TL;DR. This ingredient is the primary solvent and diluent in most personal care formulas, creating the continuous phase for gels, lotions, cleansers, and sprays. It dissolves many humectants, salts, acids, preservatives, and botanical extracts so they can be evenly distributed.
What does Water/Aqua do in a cosmetic formula?
This ingredient is the primary solvent and diluent in most personal care formulas, creating the continuous phase for gels, lotions, cleansers, and sprays. It dissolves many humectants, salts, acids, preservatives, and botanical extracts so they can be evenly distributed.
Is Water/Aqua clean?
This ingredient is broadly accepted in clean-beauty frameworks and is generally well tolerated. The main quality considerations are purification, microbial control, and preservation of the finished formula.
Is Water/Aqua sustainable?
This material is naturally abundant and cycles readily through the environment, with no persistence concern in the usual cosmetic-ingredient sense. Sustainability depends more on responsible sourcing, purification energy, wastewater practices, and regional scarcity than on the molecule itself.
Is Water/Aqua COSMOS-approved?
It is permitted under COSMOS-organic and COSMOS-natural standards, though it does not count toward organic content. From a Green Chemistry lens, it aligns well as a benign solvent with broad utility and low environmental burden when managed responsibly.
How does Water/Aqua work chemically?
The molecule is small, highly polar, and strongly hydrogen-bonding, which explains its high solvent power for ionic and polar materials. It is often the largest phase in emulsions and gels, remains stable across normal cosmetic pH ranges, and makes robust preservation necessary because finished formulas can support microbial growth.
