E1518: Glyceryl Triacetate
Main role: carrying flavors
Also listed as: triacetin, glycerol triacetate
What is E1518 (Glyceryl Triacetate)?
Glyceryl triacetate is the triacetate ester of glycerol. It is used as a carrier and can help manage the incorporation of flavors or other permitted ingredients.
What does it do in food?
Its main role is carrying flavors. A carrier helps incorporate another ingredient, while a processing ingredient may support a manufacturing step or coating. The final declaration and exposure depend on the application and the labeling rules in the relevant market.
Food and formulation examples
- Flavor preparations
- Chewing-gum formulations
- Specified additive carriers
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E1518, E 1518, or the ingredient name. Related names and label terms include triacetin, glycerol triacetate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Triacetin is different from free glycerol E422. Research that discusses glycerol-containing slush drinks should not automatically be applied to a triacetin flavor-carrier declaration.
Is E1518 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E1518 as Glyceryl triacetate (triacetin). This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
