no sulfites in methylcellulose

I searched the Dow website and they claim there are no sulfites used during their manufacturing of Methocel (methylcellulose).

There is more than one way to manufacture cellulose. One does indeed, use sulfites.

Of course, we'd have to check with each manufacturer of each product containing methylcellulose to see from which company they buy the product.

Thanks Razzle, for all your posts. I learn something new from you all the time.

I surmise not ALL products use the Dow brand Methocel methylcellulose, which is clean. It would be interesting to find out where this product comes from in our medicines, supplements and foods. Methylcellulose is used as sort of a gel or thickener to suspend medicines.

My thanks to poster 12Linus17, who noted that cellulose is made using the notorious sulfite bath that is the bane of us sensitives who would like to be able to use corn starch. If an ingredient is listed as just cellulose we should avoid it.
