Our methodology

Five criteria

Every product we review is evaluated on five publicly verifiable data points: raw material and oil type, active concentration, technical specifications (superfatting %, pH where relevant), certifications and third-party tests, and real-world user evidence (verified customer reviews at scale).

For the full Swedish methodology, see /sv/kunskap/metodik.

What we don't do

• We do not run laboratory tests ourselves.
• We do not take sponsored content in editorial articles.
• We do not guess missing data — we mark it as undeclared.
• We do not use affiliate links today.

Conflicts of interest

Fläckfri is operated by Adminor AB, which has delivered technical consulting work to Västerbottenssåpa and other Swedish companies. This is disclosed on every comparison article and on the About page. We apply the same criteria to every brand regardless of consulting relationships.
