Aqua ●
TL;DR. This ingredient is the primary solvent and diluent in many personal care formulas, dissolving salts, humectants, preservatives, and other polar materials. It also helps set texture, spread, viscosity, and product strength.
What does Aqua do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many personal care formulas, dissolving salts, humectants, preservatives, and other polar materials. It also helps set texture, spread, viscosity, and product strength.
Is Aqua clean?
It is broadly accepted in clean-beauty frameworks and is not a restricted-list concern. The main quality considerations are purification standard, microbial control, and trace contaminant specifications.
Is Aqua sustainable?
This material is mineral-derived and part of natural environmental cycles, with sustainability impact driven more by purification, heating, transport, and wastewater management than by the molecule itself. It is non-persistent in the usual cosmetic-ingredient sense.
Is Aqua COSMOS-approved?
It is permitted under COSMOS natural and organic standards, although it does not count toward organic content calculations. From a Green Chemistry view, it is a preferred benign solvent with low intrinsic reactivity and broad compatibility.
How does Aqua work chemically?
The molecule is small and highly polar, with two hydrogen atoms bonded to one oxygen atom, which explains its strong solvent behavior for ionic and polar substances. It is commonly the largest component of emulsions, gels, cleansers, and toners, often around 30% to 90%, and formulas containing it usually need appropriate preservation because it supports microbial growth.
