E463: Hydroxypropyl Cellulose
Main role: stabilizing and film formation
Also listed as: HPC, hydroxypropylcellulose
What is E463 (Hydroxypropyl Cellulose)?
Hydroxypropyl cellulose has hydroxypropyl groups attached to a cellulose backbone. This changes solubility and film-forming behavior, allowing the ingredient to support texture or coating functions in suitable formulations.
What does it do in food?
Its main role is stabilizing and film formation. Texture ingredients help a recipe control thickness, binding, or separation. Their behavior depends on temperature, acidity, concentration, and other ingredients; two thickeners with similar names may not perform identically.

Label names and ingredient questions
Look for E463, E 463, or the ingredient name. Related names and label terms include HPC, hydroxypropylcellulose. A family code can cover more than one specified form; check the full declaration when the distinction matters.
The abbreviation HPC also occurs outside food. Only food-grade specifications and the actual ingredient declaration identify the additive discussed here.
Is E463 safe?
EFSA’s 2018 cellulose assessment found no concern for the reported food uses and use levels evaluated. EFSA celluloses re-evaluation (2018).
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 E463 as Hydroxypropyl cellulose. 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.
