kosmeettisina

Kosmeettisina is a Finnish word, the essive plural form of the adjective kosmeettinen, meaning cosmetic. The essive case expresses a temporary state or role, so kosmeettisina translates roughly as “as cosmetics” or “in the capacity of cosmetics” when used with plural nouns.

The form is most commonly seen in phrases describing classification, function, or use. Typical examples include kosmeettisina tuotteina (as cosmetic products), kosmeettisina aineina (as cosmetic ingredients), and kosmeettisina ratkaisuina (as cosmetic solutions). In practice, kosmeettisina appears in contexts such as marketing, product descriptions, and scientific or regulatory writing where items are described by their cosmetic function or category.

Grammatically, kosmeettisina is the plural essive of kosmeettinen. The singular essive is kosmeettisena (e.g., kosmeettisena tuotteena, “as a cosmetic product”). This distinction mirrors Finnish noun and adjective agreement across cases and numbers, and kosmeettisina is typically used with plural nouns in the illative sense of being classified or considered as cosmetics.

Etymology traces kosmeettinen to kosmetiikka, the Finnish term for cosmetics, which itself derives from the Latin cosmēticus through European languages. The root reflects the semantic domain of cosmetics and cosmetic science, and kosmeettisina functions as a grammatical form rather than a standalone lexical item beyond its role in phrases.
