Reverse Osmosis Water ●
TL;DR. This ingredient is primarily a solvent and diluent, forming the continuous phase in many emulsions, gels, cleansers, and sprays. It helps dissolve hydrophilic ingredients and sets the base texture and concentration of the formula.
What does Reverse Osmosis Water do in a cosmetic formula?
This ingredient is primarily a solvent and diluent, forming the continuous phase in many emulsions, gels, cleansers, and sprays. It helps dissolve hydrophilic ingredients and sets the base texture and concentration of the formula.
Is Reverse Osmosis Water clean?
From a clean-beauty perspective, this ingredient is well-tolerated and broadly unproblematic. The main quality issue is microbiological control, so finished formulas still need appropriate preservation and manufacturing hygiene.
Is Reverse Osmosis Water sustainable?
This material is produced by membrane filtration rather than petrochemical synthesis. Its footprint depends on source supply, filtration energy, and management of the concentrated reject stream from processing.
Is Reverse Osmosis Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards, though it does not contribute to organic percentage calculations. It fits Green Chemistry as a benign solvent, with the main tradeoff being the energy and resource use required for purification.
How does Reverse Osmosis Water work chemically?
The molecule is small and highly polar, with strong hydrogen-bonding behavior that makes it an effective carrier for salts, humectants, acids, bases, and many botanical extracts. It is chemically stable across normal cosmetic pH ranges, but it can support microbial growth, so preservation, low bioburden, and controlled storage are important.
