puhdistavien

Puhdistavien is the genitive plural form of the present active participle puhdistava, derived from the verb puhdistaa meaning to cleanse or purify. In Finnish, participles and adjectives that convey a process or property can function as modifiers, and when they describe a plural noun in genitive, they take the suffix -ien, yielding puhdistavien. This form is used to create noun phrases that express association with cleansing.

The usage is typical in technical, scientific, or product-related language. Puhdistavien is not a standalone lexical item; it is an inflected modifier that appears before a head noun in a genitive phrase, such as puhdistavien aineiden ominaisuudet or puhdistavien valmisteiden turvallisuus. The -ien ending signals genitive plural for the -va/-vä group of adjectives and participles.

Examples:

- Puhdistavien aineiden ominaisuudet vaikuttavat puhdistustehoon. (The properties of cleansing agents affect cleaning efficacy.)

- Puhdistavien valmisteiden turvallisuus ja ympäristövaikutukset ovat tutkimuskohteita. (The safety and environmental impacts of cleansing preparations are research topics.)

Notes:

- Puhdistavien is a grammatical form rather than an independent lexical item; its meaning derives from puhdistava and the noun it modifies.

- It serves to indicate that the described substances or processes are related to cleansing or purification.
