Koostumustaso

Koostumustaso is a Finnish term used in science and industry to denote the level of detail or completeness of information about the composition of a material, product, or mixture. Broadly, it refers to what components are present and in what amounts, and to how precisely these amounts are specified.

In chemistry and materials science, it may describe the percentage by mass of each constituent in an alloy or compound, or the proportions of components in a polymer blend. In food, cosmetics and pharmaceuticals, the term can refer to how thoroughly ingredients, additives and allergens are listed on labels and safety data sheets.

Measurement and representation are usually by mass or volume percentages, mole fractions or other concentration metrics. For alloys, composition is often expressed as weight percent of each element; for formulations, ratios or percentages are used to document proportions of ingredients.

Regulatory and standards contexts often require disclosure of major components above a certain threshold and information on impurities or allergens. The specific meaning of koostumustaso thus depends on the field and the applicable regulatory framework.

The term is primarily used in Finnish language contexts. In English-language communication it can be rendered as composition level, level of composition detail, or formulation detail, depending on the context.
