Abstract
Antioksidansi su tvari koje mogu spriječiti ili usporiti oštećenje stanica uzrokovano slobodnim radikalima, nestabilnim molekulama koje tijelo stvara kao reakciju na okolišne i druge utjecaje. Primarno ih dijelimo na prirodne i sintetičke antioksidanse, te na one koji nastaju metaboličkim procesima u organizmu i na one koje je potrebno unijeti u organizam. Antioksidansi se u velikoj količini nalaze u voću i povrću, kao i u orašastim plodovima i žitaricama, te mesu peradi i ribi. U ovom radu dan je pregled različitih antioksidansa, njihova uloga i važnost u kozmetici. Na nekoliko primjera, mjerenjem oksidacijske indukcijske temperature utvrđena je oksidacijska stabilnost različitih emulzija pripravljenih s različitim antioksidansima. Cilj ovog rada bio je napraviti emulzijske sustave (kreme) prema optimalnoj formulaciji i ispitati oksidacijsku stabilnost primjenom diferencijalne pretražne kalorimetrije (DSC). Rezultati su pokazali znatan utjecaj antioksidansa ružmarina, vitamina C i hidrolata Hamamelisa na oksidacijsku stabilnost emulzija.
Abstract (english)
Antioxidants are substances that can prevent or slow down cell damage caused by free radicals, unstable molecules that the body creates in response to environmental and other influences. We primarily divide them into natural and synthetic antioxidants, and those that are formed by metabolic processes in the body and those that need to be taken into the body. Antioxidants are found in large quantities in fruits and vegetables, as well as in nuts and grains, and poultry and fish. This paper provides an overview of various antioxidants, their role and importance in cosmetics. In several examples, the oxidative stability of different emulsions prepared with different antioxidants was determined by measuring the oxidation induction temperature. The aim of this work was to make emulsion systems (creams) according to the optimal formulation and to test the oxidation stability using differential scanning calorimetry (DSC). The results showed a significant effect of the antioxidants rosemary, vitamin C and witch hazel hydrolate on the oxidative stability of emulsions.
