Koostumuksilla

Koostumuksilla is a Finnish noun phrase meaning “with compositions” or “using compositions.” It is the plural instrumental/adessive form of the noun koostumus (composition, mixture). The form is used when referring to multiple formulations or mixtures, or to indicate the means by which something is produced.

In practice, the term appears in technical and scientific writing where formulations, recipes, or ingredient ratios are discussed. It is common in fields such as chemistry, materials science, cosmetics, and food production. Texts about product formulation may refer to erilaisten koostumuksilla to compare how different formulations affect properties, performance, or safety. The phrase can also denote the set of ingredients that constitute a product rather than a single recipe.

Grammatical note: koostumuksilla derives from koostumus and is used in contexts where the writer means “with/using the compositions” or “by means of the compositions.” The singular form koostumus becomes koostumukset in nominative, koostumusten in genitive, while koostumuksilla carries the instrumental/adessive nuance.

Related terms include koostumus (composition, mixture), seos (mixture, blend), formula (formula), and resepti (recipe). Understanding the exact nuance depends on the context, but in most technical writing, koostumuksilla highlights formulations or mixtures as a variable factor.
