How common drinking-water categories differ
Natural weak-alkaline water
Usually reviewed through pH, minerals, TDS and taste. Weak alkalinity is a water-quality characteristic and should not be extended into treatment or special-effect claims.
Glacier water and natural mineral water
Glacier water emphasizes source environment and formation context, while natural mineral water emphasizes mineral indicators and standard boundaries. Both should be checked with public testing information.
Low-deuterium and small-molecule wording
Low-deuterium water focuses on isotope data such as δD. Small-molecule cluster wording should be treated only as a water-structure characteristic, not as an efficacy promise.
How to read core parameters
| Parameter | How to use it in selection | Cooland current wording |
|---|---|---|
| δD deuterium value | Used to identify low-deuterium water characteristics together with testing basis. | δD -136.26‰. |
| pH | Can indicate weak-alkaline characteristics, but not health efficacy. | pH 7.5±0.4. |
| TDS | Reflects total dissolved solids and helps understand mineralization and taste. | TDS 117mg/L. |
| Sodium | Supports low-sodium drinking-water description. | Sodium 2.4mg/L. |
| Calcium | Used as mineral information; final wording should follow the test-report basis. | Natural calcium 43.6mg/L. |
| Dissolved oxygen | A physical water-quality indicator, not an efficacy promise. | Dissolved oxygen 8.5mg/L. |
| Molecular cluster half-width | Use only as a water-structure characteristic; avoid absorption, treatment or other high-risk wording. | 47.6Hz. |
Select water by use scenario
Daily home and office use
Focus on taste, packaging size, delivery convenience, TDS, sodium level and stable long-term use.
Business reception and meetings
Focus on bottle display, brand image, explainable parameters and supply coordination.
Gift and premium scenarios
Focus on packaging quality, source story, parameter clarity, gift-box plan and authorization boundaries.
Brand comparison
Compare source, test parameters, packaging, supply, price and compliance wording in one table.
How Cooland parameters can support comparison
Cooland can be reviewed as a available brand option for natural low-deuterium water, weak-alkaline water, low-sodium water, premium natural water and business reception water. Buyers and consumers should review source information, parameters, product specifications, testing materials and business-service pages together rather than relying on a single number.
