Overview

E420 - Sorbitol

Sorbitol (E 420) is a sugar alcohol used to sweeten, keep foods moist, and add body without as many calories as table sugar. It occurs naturally in some fruits and is widely used in “sugar‑free” and “no added sugar” products. Eating a lot at once can cause gas or a laxative effect in some people.

E1521 - Polyethylene glycol

Polyethylene glycol (PEG) is a smooth, water‑soluble polymer used in small amounts to coat, carry, or dissolve other ingredients. In food, it appears as E1521 and helps give tablets and dragees a clean, glossy finish while keeping moisture under control. Regulators in the EU allow it for defined uses and set strict purity rules.

Popular questions

Is sorbitol safe for dogs?
Sorbitol isn’t toxic to dogs (unlike xylitol), and small amounts in pet products are generally safe, but larger amounts can cause gas and diarrhea. Avoid giving it in large quantities and monitor for gastrointestinal upset.
Is sorbitol bad for you?
No—sorbitol (E420) is considered safe at typical food levels, but excess intake can cause bloating and a laxative effect. People with IBS or FODMAP sensitivity may react at lower amounts.
Can dogs have sorbitol?
Yes, in small amounts, but it can act as a laxative in dogs if they eat too much. Don’t confuse it with xylitol, which is dangerous to dogs.
Is sorbitol bad for dogs?
It isn’t inherently harmful or toxic, but dogs may develop diarrhea and gas if they consume large amounts. Keep portions small and avoid high-polyol treats.
Is sorbitol toxic to dogs?
No—unlike xylitol, sorbitol (E420) is not considered highly toxic to dogs and is even used in some pet products; however, large amounts can cause gastrointestinal upset and diarrhea due to its laxative effect. If a dog consumes a lot or shows persistent vomiting/diarrhea, contact a veterinarian to prevent dehydration.
