i am allergic to propylene glycol can i use products with polyethylene glycol 4000 in it. thanks so much
Yes! I'm also allergic to propylene glycol. I've actually been tested for both propylene glycol (PG) and polyethylene glycol (PEG) and am only allergic to one. From the feedback I've gotten here on the blog, a lot of people who are allergic to PG are also allergic to PEG. As always with allergies, everybody is different.
For people who are allergic to PG, there is a rule: if the ingredients list any other word or letter before or after “Propylene Glycol”, you’re allergic to it. Take the example of Dipropylene glycol. Since nothing has literally come between the words "propylene" and "glycol", propylene glycol is indeed in the ingredient. If there’s any word or letter IN BETWEEN “Propylene” and “Glycol”, then it’s a different sort of chemical and don't worry about it. Good luck in your PG-free journey!
