So, what is e405?
E405 refers to propane-1,2-diol alginate, commonly known as propylene glycol alginate. It is a modified food additive produced by chemically esterifying alginic acid with synthetic propylene oxide. Alginic acid is a natural polysaccharide extracted from brown seaweeds, such as giant kelp, while the propylene oxide component is manufactured synthetically through chemical processes.
Manufacturers use E405 primarily as an emulsifier, thickener, and stabilizer to improve the consistency and shelf life of foods. It is commonly found in salad dressings, dairy-alternative beverages, ice creams, sauces, bakery products, and beer, where it functions to stabilize and sustain foam.
E405 is vegan because its production relies entirely on plant and synthetic materials. Brown seaweed provides the base polymer, and no animal products or animal-derived processing aids are utilized during synthesis or refinement. Consequently, E405 contains no animal ingredients.
