How to distinguish moisture in wet wipes?
The key ingredient in wet wipes is water. Pure water, RO pure water and EDI pure water are common ingredients.
What are the differences between the three?
✔ Pure water: colorless and transparent water without any additives, which can be directly drunk. It is also called distilled water because it is made by distillation in the test.
✔ RO pure water: pure water produced by RO reverse osmosis technology.
✔ EDI pure water: EDI removes residual salts in RO water by exchanging hydrogen ions or hydroxyl ions and sending them to concentrated water flow, leaving healthy small molecules that are more easily absorbed by skin.
As far as the quality standard of water products is concerned, the purity of EDI pure water is higher than that of RO pure water.
