Pregled in analiza kozmetičnih izdelkov proti prhljaju = A review and analysis of the composition of anti-dandruff cosmetic productsKastelic, Saša, farmacevtkaV diplomski nalogi smo raziskovali kozmetične izdelke (KI) proti prhljaju, ki smo jih našli v spletnih trgovinah, drogerijah in lekarnah. 50 naključno izbranim KI smo natančno analizirali sestavo in ... opredelili funkcijo vsake posamezne sestavine. Najprej smo proučili prisotnost kozmetično aktivnih sestavin (KAS), ki delujejo proti prhljaju, le-te smo razvrstili glede na njihov mehanizem delovanja. Najpogosteje uporabljena KAS je bil sintezni pirokton olamin, ki se je pojavil v 32 % vseh izdelkov, med naravnimi, pa se je najpogosteje pojavil izvleček aloe vere, ki smo ga našli v 16 % vseh pregledanih izdelkov. Osredotočili smo se tudi na površinsko aktivne snovi (PAS) ter jih razvrstili v 4 skupine (anionske, kationske, neionske, amfoterne). Pri pregledu le-teh so prevladovale neionske, ki so predstavljale 62 % vseh PAS, najmanj pogoste pa so bile kationske, predstavnice z le 10 %, kar je tudi primerno, ker veljajo za najbolj dražeče. Proučili smo tudi prisotnost sestavin, ki imajo na kožo vlažilni učinek, ter jih umestili v skupino emolientov, humektantov in okluzivov. Med humektanti je pričakovano prevladoval glicerol, ki je bil sestavina kar 48 % vseh izdelkov in s tem tudi ena izmed najpogosteje uporabljenih sestavin v našem naboru. Najpogostejši emolient je bil gliceril oleat, med okluzivi pa dimetikon. Določali smo tudi najpogosteje uporabljene konzervanse, antioksidante, zgoščevala in dišave, pri slednjih pa smo preverili ali so v izdelkih tiste, za katere je dokazano, da povzročajo neželene preobčutljive reakcije. Te dišave so v Prilogi III uredbe (ES) št. 1223/2009. Za namen mikrobiološke zaščite je bil največkrat uporabljen konzervans natrijev benzoat, predstavnik 32 % vseh izdelkov, med antioksidanti pa smo največkrat zasledili tokoferol oziroma vitamin E.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
