Resumo: | The main function of the packaging is to protect the cosmetic from the external environment, avoiding undesirable changes in the product that is contained inside, and thus indispensable for its storage and transpotation. However, its disposal improperly generates a large volume of solid waste, which is directly related to the environmental impact. One of the alternatives to minimize this impact is the use of packages made from biodegradable polymeric films based on polyacrylic acid (PLA), poly (lactic acid ? co- glycolic acid) (PLGA) and polycaprolactone (PCL), blends of theses polymers and incorporation of Zeolites 13x. The thermal, mechanical optical, water vapor barrier and degradation time in saline solution of polymeric systems are evaluated for application as cosmetic packaging. The technique used for the preparation of the polymer films was that of Solvent Casting. The polymer films were characterized by the techniques of UV-Vis Spectrophotometry, Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Scsannig Electron Microscopy (SEM), transparency, water vapor permeability, mechanical assay and absorption spectroscopy atomic. The transmittance results showed that the PCL and PLA blends showed greater blockage to the passage of radiation (190 - 1100nm) and water vapor permeability. The incorporation of PLA or PLGA to the pure PCL resulted in material with batter thermal properties, but more rigid and brittle, not modifying the degradation process until 120 days of incubation. The incorporation of 15% Zeolite 13x into the PCL/PLA blends did not significantly modify the properties evaluated. |

Por?m, o seu descarte de forma inadequada gera um grande volume de res?duos s?lidos, que est? diretamente relacionado com o impacto ambiental. Uma das alternativas para minimizar este impacto ? a utiliza??o de embalagens confeccionadas a partir de pol?meros biodegrad?veis. Desta maneira, o presente trabalho tem como objetivo a prepara??o e caracteriza??o de filmes polim?ricos biodegrad?veis baseados em Poli ? ?cido l?ctico (PLA), Poli (?cido l?ctico ? co- ?cido glic?lico) (PLGA) e Policaprolactona (PCL), blendas destes pol?meros e incorpora??o de Ze?litas 13x. S?o avaliadas as propriedades t?rmicas, mec?nicas, ?pticas, de barreira a vapor de ?gua e o tempo de degrada??o em solu??o salina dos sistemas polim?ricos, visando aplica??o como embalagem para cosm?ticos. A t?cnica utilizada para a prepara??o dos filmes polim?ricos foi a de Solvent Casting. Os filmes polim?ricos foram caracterizados pelas t?cnicas de Espectrofotometria UV-Vis, Calorimetria Explorat?ria Diferencial (DSC), An?lise Termogravim?trica (TGA), Microscopia Eletr?nica de Varredura (MEV-FEG), transpar?ncia, permeabilidade a vapor de ?gua, ensaio mec?nico e Espectroscopia de absor??o at?mica. Os resultados de transmit?ncia mostraram que a blenda de PCL e PLA apresentou maior bloqueio ? passagem de radia??o (190 nm ? 1100 nm) e ? permeabilidade de vapor de ?gua. A incorpora??o de PLA ou PLGA ao PCL puro resultou num material com melhores propriedades t?rmicas, por?m mais r?gido e quebradi?o, n?o modificando o processo de degrada??o at? 120 dias de incuba??o. A incorpora??o de 15% Ze?lita 13x ? blenda de PCL/PLA n?o modificou significativamente as propriedades avaliadas.Submitted by PPG Engenharia e Tecnologia de Materiais (engenharia.pg.materiais@pucrs.br) on 2018-06-25T13:24:34Z No. of bitstreams: 1 Dissserta??o final_Lucas Weber Dias.pdf: 2263503 bytes, checksum: ea9c29b6b538c56ea795610f7bc5a808 (MD5)Approved for entry into archive by Sheila Dias (sheila.dias@pucrs.br) on 2018-06-29T13:30:33Z (GMT) No. of bitstreams: 1 Dissserta??o final_Lucas Weber Dias.pdf: 2263503 bytes, checksum: ea9c29b6b538c56ea795610f7bc5a808 (MD5)Made available in DSpace on 2018-06-29T13:38:08Z (GMT).
