expand\ more Aqua ●
TL;DR. This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It dissolves salts, humectants, preservatives, and botanical extracts, and it often forms the continuous phase of emulsions and gels.
What does expand\ more Aqua do in a cosmetic formula?
This ingredient is the primary solvent and diluent in many beauty and personal care formulas. It dissolves salts, humectants, preservatives, and botanical extracts, and it often forms the continuous phase of emulsions and gels.
Is expand\ more Aqua clean?
From a clean-beauty perspective, this ingredient is well-tolerated and generally unproblematic. The main quality issue is purification and microbial control, since formulas built around it need an effective preservation system.
Is expand\ more Aqua sustainable?
This material has a low ingredient-level footprint, but its sustainability depends on local sourcing, purification method, and manufacturing stewardship. Biodegradability is not the relevant lens, since it is an inorganic small molecule that cycles naturally through the environment.
Is expand\ more Aqua COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, but it does not contribute to organic percentage calculations. It aligns well with Green Chemistry as a benign solvent, though responsible use and low-energy purification matter.
How does expand\ more Aqua work chemically?
The molecule is small, polar, and composed of two hydrogen atoms and one oxygen atom, which gives it strong hydrogen-bonding behavior and broad solvency for ionic and polar materials. It is commonly the largest fraction of rinse-off and leave-on formulas, and its presence makes pH control, preservative selection, and microbial testing central to formulation stability.
