Additive identity
Possible source pathways
The finished molecule can be identical across feedstocks. The Halal ruling follows the pathway, not the code alone.
E304 Possible source pathways
- plant Halal Typical Fatty acids from palm, soy, sunflower, or other vegetable oils.
- animal Halal if verified The same esters can be split from tallow or lard. Pork or non-zabiha fat is haram.
- undisclosed Halal if verified Typical Most labels print only the E-number or US name. Treat as mashbooh until a plant, vegan, or Halal claim settles the fat.
How to verify
- Match E304, INS 304, ascorbyl palmitate, or ascorbyl stearate.
- This is not plain vitamin C (E300–E302).
- Vegetarian oil or Halal formula marks settle the fat.
Quick checks
- E304 is vitamin C bonded to a fatty acid, usually palmitic acid.
- The fatty acid can be plant or animal; a vegetarian, vegan or Halal mark settles it.
- Plain vitamin C (E300–E302) has no fat question.

Why this ruling
E304 covers two fat-soluble forms of vitamin C: ascorbyl palmitate, E304(i), and ascorbyl stearate, E304(ii). Each is ascorbic acid joined to a fatty acid, which lets it dissolve in oil where plain vitamin C cannot.[1][2]
Where the question is
The vitamin C half is Halal; see E300. The fatty acid half, palmitic or stearic acid, can come from vegetable oils, most often palm, or from animal fat. That is the same question as E471, and the ruling follows the source:
- Vegetable fatty acid → Halal.
- From a Halal-slaughtered animal → Halal.
- From pork or non-Halal slaughter → not Halal.
- Not stated → Halal if verified.
Certifier lists put unsourced E304 in the doubtful group.[5] Having "ascorbic" in the name does not settle it.
What it does
Ascorbyl palmitate is an antioxidant for fats and oils. It slows rancidity, often working together with tocopherols (E306), in:
- cooking and salad oils, and oil-based sauces and dressings,
- infant formula and other foods with added fish or vegetable oils,
- dried soups, stock and snack seasonings that contain fat,
- supplements, where it is sold as "fat-soluble vitamin C".
Settling it
A vegan or vegetarian claim, or a Halal certification, settles it. Otherwise the brand can confirm whether their ascorbyl palmitate is made from palm or other vegetable fatty acids. For the fatty acids themselves, see E570.
Where you'll find it
- Antioxidant in oils, infant formula, and sausages
- Vitamin C in fat-soluble systems

Is E304 the same as vitamin C?
How do I check E304?
Scholarly view
Do not treat E304 as automatically Halal because it contains ascorbic acid. The ester is a fat-source question, like E471.
