What is E554?
Sodium aluminum silicate is a mineral compound used as an anticaking agent in powdered foods like salt, sugar, and spices. It contributes to overall dietary aluminum intake, which EFSA advises limiting because high cumulative exposure from all sources has been linked to nervous-system and reproductive effects in animal studies. At the small amounts used as an anticaking agent, it is permitted by EFSA and the FDA.
Also appears on labels as: Sodium aluminum silicate, Sodium aluminosilicate, Aluminosilicate sodium, E554, E 554, E-554, Food grade sodium aluminum silicate, Sodium aluminum silicate powder, Anticaking agent sodium aluminum silicate, Synthetic aluminosilicate, Sodium aluminum silicate additive, INS 554.
What the evidence says
- Contributes to total dietary aluminum exposure; EFSA has set a tolerable weekly intake for aluminum compounds due to potential neurological and reproductive effects seen in animal studies at high doses.
- Not a significant concern from typical anticaking-agent use levels in a single food.
