pH Determination for Detergent Safety: How Are the Values Established?
Contents
No matter how effective a detergent may be, if it’s not safe, it poses a serious risk to health. Especially for cleaning agents that contact the skin, accurate pH testing is crucial. But why is pH determination necessary and how is the right value identified? In this guide, we’ll cover all the essential information that manufacturers and consumers need to know.
What Is pH and Why Is It Important?
pH measures the acidity or alkalinity of a substance on a scale from 0 to 14:
- 0–6: Acidic (e.g., toilet cleaners)
- 7: Neutral (e.g., distilled water)
- 8–14: Alkaline (e.g., soap)
Detergent pH levels impact both product performance and skin safety.
Recommended pH Ranges by Detergent Type
| Product Type | Ideal pH Range |
|---|---|
| Laundry Detergent | 7 – 10.5 |
| Dishwashing Liquid | 6.5 – 9 |
| Surface Cleaner | 6 – 11 |
| Skin-Contact Products | 5.5 – 7.5 |
How Is pH Testing Performed?
1. Preparation
Detergent sample, distilled water, and a pH meter or pH strips are required.
2. Sample Dilution
The detergent is diluted (typically 1% solution) based on testing standards.
3. Measurement
The solution is tested using a pH meter or strips. A stable reading is taken within a minute.
4. Reporting
Results are compared with legal limits and safety thresholds, then documented.
Legal Compliance and pH Test Mandates
According to EU and Turkish regulations, cleaning products must disclose pH levels on their label, and results must be validated by laboratory services. CE and SEA compliance requires pH testing as a standard step.
