Resumo: | Microemulsion is a thermodynamically stable dispersion consisting of an aqueous and an organic phases, both stabilized by surfactant molecules and when in need, co-active surfactant. The nature and structure of these components are essential in the formulation of microemulsified systems. For this, the construction of phase diagrams can be a fundamental tool to characterize the ideal experimental conditions for the existence and operation of microemulsions. Thus, the present work had as objective to obtain a comparison between microemulsions with different compositions through the construction of ternary diagrams, aiming to achieve the most stable system. To produce microemulsified systems, a non-ionic surfactant (Ultranex NP 60), a co-surfactant (Isopropyl Alcohol), two organic phases (pine oil and castor oil) and an aqueous phase (glycerin solution) were used. Also complementing the study, rheological tests of the oleic phases were accomplished, as well as their thermogravimetric analysis. The focus of the reached ternary diagrams was to find the system with the largest Winsor type IV region (microemulsion). It was verified this region had a significant increase by the addition of the co-surfactant in the medium and using a vegetable oil, such as pine oil, since it promotes strong surfactant-oil interactions on the interface. |

La naturaleza y la estructura de estos componentes son esenciales en la formulación de sistemas de microemulsión. Para ello, la construcción de diagramas de fase es una herramienta fundamental para caracterizar las condiciones experimentales ideales para la existencia y funcionamiento de microemulsiones. Así, el presente trabajo tuvo como objetivo obtener una comparación entre microemulsiones con diferentes composiciones mediante la construcción de diagramas ternarios, con la finalidad de alcanzar un sistema más estable. Para la producción de sistemas microemulsificados se utilizó un tensioactivo no iónico (Ultranex NP 60), un cotensioactivo (alcohol isopropílico), dos fases orgánicas (aceite de pino y aceite de ricino) y una fase acuosa (solución acuosa de glicerina). También se realizaron ensayos reológicos de las fases oleicas, así como su análisis termogravimétrico. El enfoque de los diagramas ternarios logrados fue encontrar el sistema con la región de Winsor tipo IV más grande (microemulsión). Se encontró que esta región tuvo un aumento significativo debido a la adición del cotensioactivo en el medio y al uso de un aceite vegetal, como el aceite de pino, para promover interacciones fuertes entre el surfactante y el aceite en la interfaz.Microemulsão é uma dispersão termodinamicamente estável que consiste em uma fase aquosa e uma fase orgânica, ambas estabilizadas por moléculas de tensoativo e, quando necessário, um cotensoativo. A natureza e a estrutura desses componentes são essenciais na formulação de sistemas microemulsionados. Para isso, a construção de diagramas de fases é uma ferramenta fundamental para caracterizar as condições experimentais ideais para a existência e a operação de microemulsões. Assim, o presente trabalho teve como objetivo obter uma comparação entre microemulsões com diferentes composições através da construção de diagramas ternários, visando atingir o sistema mais estável. Para a produção de sistemas microemulsificados foram utilizados um tensoativo não iônico (Ultranex NP 60), um cotensoativo (álcool isopropílico), duas fases orgânicas (óleo de pinho e óleo de mamona) e uma fase aquosa (solução aquosa de glicerina). Foram realizados, também, testes reológicos das fases oleicas, bem como sua análise termogravimétrica. O foco dos diagramas ternários alcançados foi encontrar o sistema com a maior região de Winsor tipo IV (microemulsão). Verificou-se que essa região teve um aumento significativo pela adição do cotensoativo no meio e utilização de um óleo vegetal, como o óleo de pinho, por promover fortes interações tensoativo-óleo na interface.Research, Society and Development2021-02-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1290210.33448/rsd-v10i2.12902Research, Society and Development; Vol. 10 No. 2; e58410212902Research, Society and Development; Vol. 10 Núm. 2; e58410212902Research, Society and Development; v. 10 n. 2; e584102129022525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/12902/11632Copyright (c) 2021 Fabiola Dias da Silva Curbelo; Alfredo Ismael Curbelo Garnica; Beatriz Sales Cavalcanti Nascimento; Giovanna Lais Rodrigues Leal; Tarsila Melo Tertuliano; Raphael Ribeiro da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCurbelo, Fabiola Dias da SilvaGarnica, Alfredo Ismael Curbelo Nascimento, Beatriz Sales Cavalcanti Leal, Giovanna Lais Rodrigues Tertuliano, Tarsila Melo Silva, Raphael Ribeiro da 2021-03-02T09:32:39Zoai:ojs.pkp.sfu.ca:article/12902Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:21.549597Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
