Selvom denne test er afg\u00f8rende for mange kosmetiske produkter, er den ikke automatisk p\u00e5kr\u00e6vet for alle formuleringer, der markedsf\u00f8res i Europa. <\/p>\n<p data-start=\"842\" data-end=\"969\">Den europ\u00e6iske kosmetiklovgivning fastsl\u00e5r ikke udtrykkeligt, at hvert enkelt kosmetisk produkt skal underkastes en test af konserveringsmidlernes effektivitet.<\/p>\n<p data-start=\"971\" data-end=\"1337\">I stedet kr\u00e6ver forordning (EF) nr. 1223\/2009, at producenterne skal sikre, at kosmetiske produkter er sikre for menneskers sundhed under normale eller rimeligt forudsigelige anvendelsesforhold. Som en del af sikkerhedsrapporten for kosmetiske produkter (CPSR) skal sikkerhedsvurdereren vurdere produktets <a href=\"https:\/\/www.certifiedcosmetics.com\/da\/blog\/laboratorieundersogelser\/mikrobiologisk-kvalitet-af-kosmetik\/\">mikrobiologiske kvalitet<\/a> og overveje, om konserveringssystemet er tilstr\u00e6kkeligt. <\/p>\n<p data-start=\"1339\" data-end=\"1536\">For produkter, hvor der anvendes <a href=\"https:\/\/www.certifiedcosmetics.com\/da\/blog\/kosmetiske-ingredienser\/konserveringsmidler-tilladt-i-kosmetik-eu\/\">konserveringsmidler<\/a> til at begr\u00e6nse mikrobiel v\u00e6kst, er en test af konserveringsmidlets effektivitet ofte den mest hensigtsm\u00e6ssige metode til at p\u00e5vise, at konserveringssystemet fungerer som tilsigtet.<\/p>\n<p data-start=\"1538\" data-end=\"1714\">I praksis anerkendes test af konserveringsmidlers effektivitet bredt som den videnskabelige standardmetode til at freml\u00e6gge dette bevis, selvom dette ikke udtrykkeligt er fastsat i forordningen.<\/p>\n<h2 data-section-id=\"k87869\" data-start=\"1716\" data-end=\"1780\">Hvilke produkter kr\u00e6ver normalt test af konserveringsmidlernes effektivitet?<\/h2>\n<p data-start=\"1782\" data-end=\"1941\">Generelt anbefales det at foretage test af konserveringsmidlernes effektivitet for kosmetiske produkter, der er udsat for mikrobiel kontaminering under opbevaring og brug af forbrugerne.<\/p>\n<p data-start=\"1943\" data-end=\"1981\">Dette omfatter typisk produkter, der:<\/p>\n<ul data-start=\"1983\" data-end=\"2209\">\n<li data-section-id=\"1rx9bwv\" data-start=\"1983\" data-end=\"2025\">Indeholder vand eller vandbaserede ingredienser<\/li>\n<li data-section-id=\"190b2p1\" data-start=\"2026\" data-end=\"2099\">Er pakket i beholdere, der tillader gentagen kontakt med produktet<\/li>\n<li data-section-id=\"ji4o9p\" data-start=\"2100\" data-end=\"2145\">Er beregnet til gentagen brug efter \u00e5bning<\/li>\n<li data-section-id=\"1werodt\" data-start=\"2146\" data-end=\"2209\">Kan med rimelighed blive forurenet ved normal brug af forbrugeren<\/li>\n<\/ul>\n<p data-start=\"2211\" data-end=\"2361\">Typiske eksempler er ansigtscremer, kropslotioner, shampoo, balsam, flydende s\u00e6be, rensegeler, serum og mange hudplejeprodukter, der ikke skal skylles af.<\/p>\n<p data-start=\"2363\" data-end=\"2549\">Da mikroorganismer har brug for vand for at vokse, er disse formuleringer generelt afh\u00e6ngige af et effektivt konserveringssystem for at forblive mikrobiologisk sikre i hele deres forventede holdbarhedsperiode.<\/p>\n<h2 data-section-id=\"blu2h6\" data-start=\"2551\" data-end=\"2615\">Hvilke produkter beh\u00f8ver muligvis ikke at gennemg\u00e5 test af konserveringsmidlernes effektivitet?<\/h2>\n<p data-start=\"2617\" data-end=\"2687\">Ikke alle kosmetiske formuleringer udg\u00f8r den samme mikrobiologiske risiko.<\/p>\n<p data-start=\"2689\" data-end=\"2887\">Produkter, der indeholder meget lidt eller <a href=\"https:\/\/www.certifiedcosmetics.com\/da\/product\/verifikation-af-anprisninger-og-test-af-ingredienser\/test-til-bestemmelse-af-vandaktivitet-aw\/\">slet intet vand,<\/a> er naturligvis mindre gunstige for mikrobiel v\u00e6kst.
