Elaboração de um creme hidratante com extrato de butiá (Butia Yatay)

Abstract

The butiá is a subtropical palm tree of the Arecaceae (Palmae) family, that is distributed manly in Rio Grande do Sul. Factors such as monoculture, extensive livestock, population growth, commercial and real estate development contributed to some species of butiá presenting risk of extinction in Rio Grande do Sul. Therefore, new actions must be considered that contribute to the renewal of cultural practices and investments in the palm tree. The use of natural resources to incorporate bioactives in cosmetics that promote maintenance and health benefits has become recurrent. The present work is seen as an opportunity to unite the cosmetics market with the new practices of using butia. For this reason, the main goal is to elaborate a moisturizing cream using butiá’s pulp extract. The raw material used was the pulp and peel of Butiá yatay, after that, the material was dried, grinded and characterized. Later, an extract was produced through the maceration and characterization technique. The elaboration of the creams happened in different concentrations, 50 and 75% of extract in its composition. Subsequent, the characterization of the formulation was made, through viscosity and stability verifying tests. The powder of the butiá’s peel and pulp dry and milled showed a mean Sauter diameter of 0.6346 mm and a moisture content of 18.5454 ± 0.0947 % (b.u). The extract presented 13.950 ± 0.409% of antioxidant activity, 8.39.10-5 ± 7.56 10-6 mgGAE.g-1 b.s of phenolic compounds and 14.576 ± 0.109 mg of cyanidin/100g b.s of anthocyanins. The products were characterized through analysis, showing a viscosity of 1774.142 ± 65.390 cP for the control cream, 726.333 ± 41.591 cP for CAB-50% and 717.942 ± 85.897 cP for CAB-75%.In the study of the stability of the creams, all of them presented a normal appearance, not requiring their reformulation. The coloration of the creams shows the predominance of white color and similar coloration for all the developed formulations, with the presence of green, red, yellow and blue colors, but in small quantities, without predominance of any of them. The pH decreased in the formulations with the incorporation of butiá extract, but remained close to the pH of the skin. Through the analysis of the bioactives present in the extract, it was possible to verify that Butiá yatay has great potential for application in moisturizing cream.
