luktfria

Luktfria is a Swedish term meaning odorless or without detectable smell. The word is formed from lukt (smell) and fri (free of). Grammatically, luktfri is used for singular nouns, while luktfria is used for plural nouns (for example, luktfria produkter).

The term is commonly used on product labels and in safety or consumer guidance to indicate that a substance or environment emits little or no odor. It is applied across contexts such as cleaning agents, solvents, cosmetics, medicines, and air-purifying devices, as well as in settings where a neutral or odor-free environment is preferred, like healthcare or food service. Luktfria can refer to products that are inherently odorless or to formulations designed to have no added fragrance.

Odor perception is inherently subjective, so measuring odor strength can be challenging. In professional contexts, odor levels may be assessed using olfactometry or other standardized methods involving panels to estimate odor concentration. Regulatory practices and labeling requirements related to odor or fragrance vary by country and product category, and there is no universal legal definition of luktfri across all Swedish law. In practice, the label aims to inform consumers about fragrance-free or low-odor properties rather than certify a precise odor threshold.
