AI Article Synopsis

  • The study explored gluten levels in oral hygiene and cosmetic products sold in Italy, specifically targeting products labeled gluten-free or with unknown gluten content.
  • Out of 66 products tested, 94% were found to have gluten levels below 20 parts per million (ppm), indicating they are safe for celiac disease patients.
  • Only 6% of the products contained higher levels of gluten, with no ingredients derived from wheat, barley, or rye present in any of the tested items.

Article Abstract

Objectives: The only available treatment for celiac disease (CD) is the gluten-free diet. It is unclear whether the presence of gluten in oral hygiene products and cosmetics that are applied on the mouth is a reason of concern for CD patients. The aim of this study was to test the level of gluten contamination in oral hygiene and cosmetic products available in the Italian market.

Methods: A total of 66 products (toothpastes = 37; dental tablets = 2; mouthwashes = 5; lip-balms = 10; lipsticks = 12) labelled gluten-free or with unknown gluten content were randomly collected from different supermarkets and pharmacies. The gluten quantification was determined by the R5 ELISA method approved by EU regulations.

Results: Out of 66 oral hygiene and cosmetics, 62 products (94%) were found to be gluten-free (gluten level <20 ppm), while 4 (6%) (toothpastes = 3; lipsticks = 1) showed a gluten level >20 ppm (toothpastes: 20.7, 31.4, and 35 ppm; lipstick: 27.4 ppm). None of the selected products had ingredient derived from wheat, barley, or rye.

Conclusions: Gluten contamination is currently not an issue in a wide array of cosmetic and oral hygiene products that are commonly in the market.
