Estudo de compostos naturais de acerola (Malphigia emarginata D.C.) para cosméticos

Abstract

The cosmeceuticals emerged from the population’s need to ally body’s care to products that use naturals resources, ensuring a sustainable development of new technologies explored by the HPPC’s business (Personal hygiene, Perfumery and Cosmetics). Following this thinking, this project consisted in study new possibilities of utilization of this raw material of a vegetal resource, acerola, as an antioxidant agent of a natural occurence to use in cosmetic products. The enzimatics and non enzimatics actives, such as SOD (Superoxide dismutase) and Vitamin C, respectively, contributes to the preserve free radical activity. To evaluate the antioxidants properties, acerola frozen pulps was submitted to dialysis process, after that, to lyophilization and vitamin C analysis by iodometric method and SOD activity determined by Blue photoreduction of nitroblue tetrazolium (NBT), spectrophotometrically monitored. Through the analysis the found values was near the values described in literature, characterizing the raw material chosen as a good alternative to product development, attending to desired claims. According to the positive results of the analysis, the cosmetic bases were developed with the proposed formulation and finally subimitted to stability process analysis, during 45 days. To develop the analysis, the samples were stored in translucent packaging (for better macroscopic examination of possible changes in the product) in pre-established conditions of Greenhouse 37ºC, Ambient Temperature, Refrigerator 4ºC and Fluorescent light. According to the result, creamy gel it’s the better proposal because it’s have greater adherence to the lyophilized vegetable raw material and better stability in the conditions above mentioned.
