Measuring pH of Stabilized Vitamin C Glycol
Question
I measured the pH of Stabilized Vitamin C Glycol using pH paper and got a value of 4.5. However, the product information states the pH is 2-3. Why is there a difference in the measured pH, and what is the correct method to measure the pH of this product?
Answer
Hello,
I understand you have questions about the pH of Stabilized Vitamin C Glycol measured with pH paper, which differs from the product information.
According to the staff's advice, measuring the pH of Stabilized Vitamin C Glycol directly is difficult because the product does not contain water as a main component. pH measurement requires a solution that contains water.
Using pH paper on a product without water can result in inaccurate readings.
The correct method for measuring the pH of Stabilized Vitamin C Glycol is:
- Dilute the Stabilized Vitamin C Glycol in water first (recommended concentration around 10-20%).
- Then, use a pH measuring tool (such as a digital pH meter) to measure the pH of the diluted solution.
The pH value stated in the product details (2-3) is likely the value obtained when measured correctly after dilution in water. Therefore, the value of 4.5 measured directly with pH paper might be due to the limitation of the measurement method for this type of product.
