Does Pvp Contain Gluten?

Hi there! I'm getting confused again with hidden ingredients. Does anyone know what PVP is? It is in some of my hair products and the company says they are gluten free. But I know I've seen that Hydrolyzed Wheat Protein is often listed next to PVP Copolymer. Are there different kinds of PVP? Bottom line...does anyone know if PVP contains gluten??

Thanks!

Jennifer

from the BASF site

Polyvinylpyrrolidone (PVP) is a white, hygroscopic powder with a weak characteristic odor. In contrast with most polymers, it is readily soluble both in water and in a large number of organic solvents, such as alcohol, amines, acids, chlorinated hydrocarbons, amides, and lactams. On the other hand, the polymer is insoluble in common esters, ethers, hydrocarbons, and ketones.

The marked hygroscopicity of PVP and adhesion to different materials are characteristic properties of PVP. This property combined with outstanding film formation, high capacity for complex formation, good stabilizing and solubilizing capacity, insensitivity to pH, ready radiation-induced crosslinkability as well as good biological compatibility have made PVP one of the most frequently used specialty polymers.

PVP is a synthesized by free-radical polymerization of N-vinylpyroolindone in water or alcohols with a suitable initiator. By selecting suitable polymerization conditions, a wide range of molecular weights can be obtained extending from low (a few thousand daltons) to very high (1-2 million daltons).

      Trying to read my lab results

      By trents · Posted

      You have three celiac disease specific antibody tests that are positive: Endomysial  Antibody IGA (aka, EMA), tTG-IGA, and tTG_IGG. Furthermore, your Immunoglobulin A at 55 is low, meaning you are IGA deficient. This one is not an antibody test for celaic disease per se but a measure of "total IGA" levels and if low (yours is low) it can suppress the individual antibody scores and even cause false negatives. So, yes, it definitely looks like you have celiac disease.   Do not yet begin a gluten free diet as your physician may refer you to a GI doc for an endoscopy/biopsy of the small bowel lining for confirmation of the antibody testing. This may help:

      Trying to read my lab results

      By Bayb · Posted

      Hi, I received my labs via email yesterday and have not heard back from my doctor yet. Can anyone tell me if these results indicate I have Celiac?      Endomysial Antibody IgAPositive  Ft-Transglutaminase (tTG) IgA6  H0-3 (U/mL) - Negative 0 - 3 - Weak Positive 4 - 10 - Positive >10 - Tissue Transglutaminase (tTG) has been identified as the endomysial antigen. Studies have demonstrated that endomysial IgA antibodies have over 99% specificity for gluten-sensitive enteropathy. FImmunoglobulin A, Qn, Serum55  L87-352 (mg/dL) Ft-Transglutaminase (tTG) IgG183  H0-5 (U/mL) - Negative 0 - 5 - Weak Positive 6 - 9 - Positive >9

      Constant low back, abdominal and pelvic pain!

      By Aussienae · Posted

      Mine is definitely triggered by inflammation and stress! I do also have arthritis in my spine, but the pain is more in my pelvic area. Im sure i have other food intolerances or other autoimmune isues but the more I focus on it and see doctor after doctor, it just gets worse.  Best thing is get of Gluten! (I also avoid lactose). Try to limit stress and anything that causes inflammation in your body.

      By ButWhatCanIEat · Posted

      Good morning,   I got an email about replies to this post. Some of my doctors had blamed a slipped disc for the pain I had and that contributes, but after meeting with a gastroenterologist AGAIN and trying some lifestyle modifications, I found out I have IBS and can't tolerate corn or excessive fructose to any degree. Cutting out corn AFTER having cut out all gluten containing products was a real pain but I feel much better now!

      Isolated DPG-Iga

      By trents · Posted

      So, I contacted Scott Adams, the author of that article and also the creator/admin of this website, and pointed out to him the need to clarify the information in the paragraph in question. He has now updated the paragraph and it is clear that the DGP-IGA does serve the purpose of circumventing the false negatives that IGA deficiencies can generate in the tTG-IGA antibody test.
