คำตอบ
Subject: Difference between pure and regular Sodium Bicarbonate and skin irritation
Hello,
Chemicals come in various grades.
- For synthetic chemicals, high-purity chemicals undergo additional processes to increase purity and reduce impurities that naturally occur during production.
- The same chemical might be used for different purposes (e.g., industrial cleaning vs. cosmetic use), requiring different grades or purities.
Regarding allergies:
- If you are already allergic to Sodium Bicarbonate, you will be allergic regardless of the grade used.
- If you are not allergic to Sodium Bicarbonate itself, using a higher grade might reduce the risk of irritation because lower grades often contain other impurities from the production process.
- Cosmetic grade chemicals have specific standards for various impurities, such as limiting heavy metals (e.g., no more than 20ppm) and prohibiting arsenic contamination.
Thank you.
