pohjaaineisiin

Pohjaaineisiin is the illative plural form of pohja-aine, a Finnish term meaning base ingredient or base substance. In Finnish technical language, pohja-aineet refer to the components that form the primary matrix or base of a formulation. They are used across diverse sectors such as paints and coatings, plastics, cosmetics, pharmaceuticals, and food processing. The base ingredients determine core properties like texture, viscosity, drying or curing behavior, and chemical stability, and they interact with additives to tailor performance.

Practically, formulators select pohjaaineet to establish a product’s fundamental characteristics. In paints and coatings, base ingredients typically include binders or resins and solvents or water; in cosmetics, emulsions provide the base for creams and lotions; in plastics, the polymer matrix acts as the core. Additives such as pigments, fillers, stabilizers, plasticizers, and surfactants are introduced with the pohjaaineisiin to modify color, durability, processing, and application properties.

Quality, safety and regulation are important when choosing pohjaaineisiin. Criteria include chemical compatibility with additives, purity and lot-to-lot consistency, environmental impact and worker safety, and compliance with product-specific regulations. Technical data sheets and safety datasheets define acceptable pohjaaineisiin for a given formulation and specify handling, storage, and disposal requirements.

Usage notes: the term is primarily found in Finnish industrial and scientific writing. It appears as pohjaaineisiin in sentences describing formulation steps, for example: "Pohja-aineisiin sekoitetaan lisäaineet".
