Xanthan gum is not banned in Europe. It is an authorized food additive in the European Union, classified under the E-number system as E 415. The European Commission permits its use across multiple food categories, and it also appears widely in European cosmetic products like toothpaste, body lotions, and gels.
EU Regulatory Status of Xanthan Gum
Xanthan gum is legally approved for use in food throughout the EU under Regulation (EC) No 1333/2008, which governs all food additives sold in member states. The European Commission’s food additive database lists E 415 as authorized across numerous food categories, in many cases at “quantum satis,” a Latin term meaning manufacturers can use as much as needed to achieve the desired effect, with no fixed maximum limit.
The EU does periodically re-evaluate food additives that were approved before January 2009, and xanthan gum is part of that process. The European Food Safety Authority (EFSA) has issued scientific opinions on its safety and has called for additional technical and toxicological data from interested parties. This is routine for all legacy food additives, not a signal that a ban is under consideration. A 2026 Commission regulation further amended the rules around xanthan gum’s use, confirming its continued authorization.
Why the Confusion Exists
The idea that xanthan gum might be banned in Europe likely stems from the EU’s generally stricter approach to food additive regulation compared to the United States. The EU does ban or restrict certain additives that the FDA permits freely, which leads to viral lists of “ingredients banned in Europe.” Xanthan gum is not on those lists. Both the FDA and the EU consider it safe for general food use.
Another source of confusion is the EU’s specific restrictions around infant products, which are more cautious than general food rules. These restrictions sometimes get mischaracterized as outright bans.
Restrictions for Infants
The one area where European regulators have exercised real caution involves very young children. Cases of necrotizing enterocolitis, a serious and sometimes fatal intestinal condition, have been reported in newborns (mostly premature) who consumed formula thickened with xanthan gum or locust bean gum to treat reflux. EFSA has reviewed these cases and noted that the available information doesn’t allow firm conclusions about whether xanthan gum directly caused the condition.
Despite the uncertain link, xanthan gum is only permitted in specific infant food categories under tightly controlled conditions, particularly in dietary foods for special medical purposes and special formulae for infants. This is a precautionary restriction, not a ban, and it applies specifically to products for infants below 16 weeks of age. For the general population, including older children and adults, no such restrictions exist.
Digestive Effects at High Doses
Xanthan gum is a soluble fiber produced by fermenting sugar with a specific bacterium. In typical amounts found in processed foods (usually a fraction of a percent of the product), most people tolerate it without issues. At higher doses, it can have a mild laxative effect and cause bloating or gas, similar to other soluble fibers.
Animal research has raised some questions worth noting. A study published in PLOS One found that rats fed xanthan gum at various doses developed mild to moderate colon inflammation and changes in gut bacteria composition. The doses used in animal studies are often much higher relative to body weight than what a person would typically consume from food, so these findings don’t translate directly to human dietary exposure. Still, they illustrate why regulatory bodies like EFSA continue to collect data and re-evaluate the additive’s safety profile over time.
Xanthan Gum in European Cosmetics
Beyond food, xanthan gum is a standard ingredient in cosmetic products sold across Europe. It functions as a thickener, emulsion stabilizer, and gel-forming agent in everything from toothpaste to makeup. The EU Cosmetic Regulation, which is notably strict compared to US cosmetic rules, does not restrict or limit xanthan gum concentrations in personal care products. It is listed in the European cosmetic ingredient database (COSMILE Europe) without any safety flags or usage caps.
