Consumer Advice
Glacial acetic acid is concentrated acetic acid, the main component of vinegar. It is used as an acidity regulator and preservative in condiments, pickles, salad dressings and sauces. It occurs naturally in fermented foods and is metabolised normally by the body. At the permitted levels it is very safe; the concentrated form is corrosive, but only dilute food-grade solutions are ever used in food.
