\"\"Pri razpravi o preskusih stabilnosti kozmeti\u010dnih izdelkov se v tehni\u010dni dokumentaciji in laboratorijskih protokolih pogosto pojavlja en sklic: ISO\/TR 18811:2018<\/strong>. Proizvajalci pogosto domnevajo, da gre za obvezen preskusni standard ali da predpisuje dolo\u010den laboratorijski postopek. V resnici pa nobeno od tega ne dr\u017ei.<\/p>\n

ISO\/TR 18811 je tehni\u010dno poro\u010dilo<\/strong>, ki vsebuje znanstvene smernice o tem, kako je treba pristopiti k presku\u0161anju stabilnosti kozmeti\u010dnih izdelkov. Namesto da bi dolo\u010dalo obvezne preskusne pogoje ali sprejemljiva merila, ponuja okvir, ki proizvajalcem pomaga pri oblikovanju ustreznih \u0161tudij stabilnosti na podlagi lastnosti posameznega izdelka.<\/p>\n

Razumevanje vloge standarda ISO\/TR 18811 kozmeti\u010dnim blagovnim znamkam pomaga pri pravilni interpretaciji laboratorijskih poro\u010dil ter pri razvoju programov testiranja, ki so znanstveno utemeljeni in skladni z evropskimi regulativnimi zahtevami.<\/p>\n

Kaj je ISO\/TR 18811?<\/h2>\n

Mednarodna organizacija za standardizacijo (ISO) je objavila standard ISO\/TR 18811:2018<\/strong>, Kozmetika \u2013 Smernice za presku\u0161anje stabilnosti kozmeti\u010dnih izdelkov<\/em>, da bi zagotovila navodila za ocenjevanje stabilnosti kozmeti\u010dnih izdelkov.<\/p>\n

Pomembno je, da gre pri tem dokumentu za tehni\u010dno poro\u010dilo (TR)<\/strong> in ne za mednarodni standard. Ta razlika je pomembna. Za razliko od standarda, ki dolo\u010da obvezne zahteve ali podrobne preskusne metode, tehni\u010dno poro\u010dilo vsebuje priporo\u010dila, osnovne informacije in dobre znanstvene prakse. Proizvajalcem pomaga razumeti, kako se lahko na\u010drtujejo preskusi stabilnosti, vendar kon\u010dno strategijo presku\u0161anja prepu\u0161\u010da podjetju, odgovornemu za dajanje izdelka na trg.<\/p>\n

Ali je standard ISO\/TR 18811 obvezen v Evropski uniji?<\/h2>\n

Ne. Niti Uredba (ES) \u0161t. 1223\/2009<\/strong> niti nobena uradna evropska smernica ne zahteva, da proizvajalci izrecno upo\u0161tevajo standard ISO\/TR 18811.<\/p>\n

Vendar pa Uredba zahteva, da so kozmeti\u010dni izdelki varni v normalnih ali razumno predvidljivih pogojih uporabe. Dokazovanje stabilnosti izdelka je del znanstvenih dokazov, ki podpirajo to oceno varnosti.<\/p>\n

Ker standard ISO\/TR 18811 odra\u017ea mednarodno priznana znanstvena na\u010dela, ga mnogi laboratoriji in strokovnjaki na podro\u010dju regulative uporabljajo kot referenco pri na\u010drtovanju \u0161tudij stabilnosti in dokumentiranju njihove utemeljitve.<\/p>\n

Kaj dejansko navaja standard ISO\/TR 18811?<\/h2>\n

Eno najpomembnej\u0161ih sporo\u010dil standarda ISO\/TR 18811 je, da ne obstaja splo\u0161ni protokol za presku\u0161anje stabilnosti, ki bi bil primeren za vsak kozmeti\u010dni izdelek<\/strong>.<\/p>\n

Poro\u010dilo priznava izjemno raznolikost kozmeti\u010dnih formulacij, sistemov pakiranja, pogojev shranjevanja in namembnih uporab. Zato poro\u010dilo ugotavlja, da bi morali proizvajalci oblikovati in utemeljiti svoje lastne protokole stabilnosti na podlagi znanstvenih utemeljitev, namesto da bi sledili enemu samemu vnaprej dolo\u010denemu postopku.<\/p>\n

Ta pro\u017een pristop je skladen z evropsko zakonodajo o kozmeti\u010dnih izdelkih, ki proizvajalcu nalaga odgovornost, da za vsak posamezen izdelek predlo\u017ei ustrezna dokazila.<\/p>\n

Standard ISO\/TR 18811 obravnava glavne elemente, ki jih je treba upo\u0161tevati pri na\u010drtovanju programa stabilnosti. Med obravnavanimi temami so:<\/p>\n

    \n
  • Znanstvena na\u010dela, na katerih temelji stabilnost kozmeti\u010dnih izdelkov<\/li>\n
  • Dejavniki, ki lahko vplivajo na stabilnost izdelka<\/li>\n
  • Izbira ustreznih preskusnih metod<\/li>\n
  • Pogoji shranjevanja in zasnova \u0161tudije<\/li>\n
  • Ocena rezultatov stabilnosti<\/li>\n
  • Dokumentiranje zaklju\u010dkov<\/li>\n<\/ul>\n

    Poro\u010dilo prav tako pregleduje obstoje\u010de znanstvene vire in \u017ee objavljena navodila ter proizvajalcem ponuja koristen okvir za izbiro ustreznih strategij testiranja.<\/p>\n

    Kako naj proizvajalci uporabljajo standard ISO\/TR 18811?<\/h2>\n

    Za ve\u010dino kozmeti\u010dnih podjetij je standard ISO\/TR 18811 bolj referen\u010dni dokument kot pa seznam za preverjanje skladnosti.<\/p>\n

    To proizvajalcem pomaga razumeti, zakaj se programi presku\u0161anja stabilnosti med posameznimi izdelki razlikujejo in zakaj laboratoriji lahko priporo\u010dajo razli\u010dne zasnove \u0161tudij, odvisno od ocenjevane formulacije.<\/p>\n

    Namesto da se spra\u0161ujemo, ali je izdelek \u00bbtestiran v skladu z ISO\/TR 18811\u00ab, je obi\u010dajno bolj primerno vpra\u0161ati, ali je bil program stabilnosti oblikovan na podlagi znanstveno utemeljenih na\u010del, ki so skladna s priporo\u010dili tega standarda.<\/p>\n","protected":false},"excerpt":{"rendered":"
