Cocamidopropyl Betaine: Allergen Concerns and Purity
คำถาม
Hello. I am a regular customer and am very impressed with the quality of products and the excellent customer service. I have a question regarding a chemical ingredient, [url=http://www.myskinrecipes.com/shop/%E0%B8%AA%E0%B8%B2%E0%B8%A3%E0%B8%A5%E0%B8%94%E0%B9%81%E0%B8%A3%E0%B8%87%E0%B8%95%E0%B8%B6%E0%B8%87%E0%B8%9C%E0%B8%B4%E0%B8%A7/160-cocamidopropyl-betaine-coco-betaine.html:1uzp0vdn]Cocamidopropyl Betaine[/url:1uzp0vdn]. My family and I use products containing it without experiencing any allergic reactions and find them very good. However, I have seen on several websites that this ingredient is attacked as an allergen, even being named "Allergen of the Year" in 2004 by The American Contact Dermatitis Society. But after searching for more information from various international websites, I haven't found evidence of severe allergies as claimed by some sites. Is it possible that current [url=http://www.myskinrecipes.com/shop/%E0%B8%AA%E0%B8%B2%E0%B8%A3%E0%B8%A5%E0%B8%94%E0%B9%81%E0%B8%A3%E0%B8%87%E0%B8%95%E0%B8%B6%E0%B8%87%E0%B8%9C%E0%B8%B4%E0%B8%A7/160-cocamidopropyl-betaine-coco-betaine.html:1uzp0vdn]Cocamidopropyl Betaine[/url:1uzp0vdn] formulations since 2004 have improved regarding the contamination of aminoamide (AA) and 3-dimethylaminopropylamine (DMAPA), leading to a significant reduction in the number of people who experience allergies? I understand that allergic reactions to cleansing agents are individual and vary in severity, but is [url=http://www.myskinrecipes.com/shop/%E0%B8%AA%E0%B8%B2%E0%B8%A3%E0%B8%A5%E0%B8%94%E0%B9%81%E0%B8%A3%E0%B8%87%E0%B8%95%E0%B8%B6%E0%B8%87%E0%B8%9C%E0%B8%B4%E0%B8%A7/160-cocamidopropyl-betaine-coco-betaine.html:1uzp0vdn]Cocamidopropyl Betaine[/url:1uzp0vdn] considered mild and less likely to cause allergies compared to other cleansing agents on the market? This is because I see [url=http://www.myskinrecipes.com/shop/%E0%B8%AA%E0%B8%B2%E0%B8%A3%E0%B8%A5%E0%B8%94%E0%B9%81%E0%B8%A3%E0%B8%87%E0%B8%95%E0%B8%B6%E0%B8%87%E0%B8%9C%E0%B8%B4%E0%B8%A7/160-cocamidopropyl-betaine-coco-betaine.html:1uzp0vdn]Cocamidopropyl Betaine[/url:1uzp0vdn] in almost all gentle cleansing products on the market. Could you please explain and provide more information? Thank you.

Thank you for your kind words and for being a valued customer! We're delighted to hear you are happy with our products and service.
Regarding your question about Cocamidopropyl Betaine (CAPB), you are absolutely right to bring this up, and your understanding is quite accurate.
It is true that Cocamidopropyl Betaine was named the "Allergen of the Year" in 2004 by the American Contact Dermatitis Society. However, subsequent research, as you found, indicated that the allergic reactions were primarily caused by impurities, specifically aminoamide (AA) and 3-dimethylaminopropylamine (DMAPA), which were byproducts of the manufacturing process at the time.
Since then, manufacturing processes have improved significantly, resulting in highly purified grades of CAPB with very low levels of these impurities. This is why, as you observed, allergic reactions to modern CAPB are much less common than they might have been in the past.
You are also correct that Cocamidopropyl Betaine is generally considered a mild surfactant. It is often used in combination with other surfactants to reduce the overall irritation potential of a cleansing product, making it suitable for sensitive skin and commonly found in "gentle" or "tear-free" formulations. While individual sensitivity varies, CAPB is typically less irritating than anionic surfactants like Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES).
Your personal experience of using products with CAPB without issue aligns with the current understanding of purified CAPB being well-tolerated by most people.
We appreciate you sharing the additional information you found; it accurately reflects the scientific consensus on this topic.
We hope this explanation is helpful!
