Koolhoudende

Koolhoudende is a nonstandard spelling of the Dutch adjective koelhoudende, used to describe objects, substances, or systems that maintain a cool temperature or minimize temperature rise. In formal Dutch, the correct form is koelhoudende.

Etymology and spelling notes: the term is formed from koel (cool) and houdend (holding). The present participle suffix -ende attaches to the stem to indicate a continuing action. The spelling koolhoudende with double o is commonly considered a misspelling, potentially stemming from confusion with kool (cabbage) or from typographical error.

Usage and contexts: the term appears in technical writing related to refrigeration, packaging, storage, and thermal management. It can modify nouns such as vloeistof (liquid), verpakking (packaging), installatie (system), or materiaal (material), signaling that the object has cooling properties or is designed to keep temperatures low.

Related terms and concepts: in many contexts, more precise terms are used, such as koelvloeistof (coolant) or koelmiddel (cooling agent). Other relevant concepts include koeltechniek (cooling technology), koelopslag or thermische opslag (thermal storage), and faseveranderingsmateriaal (phase-change material) for temperature regulation.

Spelling and style: koelhoudende is the preferred form in Dutch; koolhoudende is generally considered a misspelling. In informal writing, you may still encounter the erroneous variant, but it is advisable to use the standard koelhoudende in formal or technical texts.
