tillsatta

Tillsatta is the past participle of the Swedish verb tillsätta, meaning to add or introduce something to a mixture, product, or system. In use, tillsatta describes substances that have been added to something else and can function as an adjective or as part of a verb phrase in compound forms.

The term appears widely in consumer labeling, technical writing, and regulatory contexts. It is used to indicate ingredients or components that were deliberately introduced to a product. Common contexts include food and drink, cosmetics, medicines, and chemical formulations. Typical phrases include tillsatta vitaminer or tillsatta konserveringsmedel, referring to vitamins or preservatives that have been added.

Grammatical use varies with the noun it modifies. In plural contexts, tillsatta is commonly seen: tillsatta ämnen, tillsatta färgämnen. In singular contexts, a different form of the participle or related construction may be used depending on the noun and syntax. The word is derived from tillsätta, and it remains a standard way to express that something has been added to something else.
