Inclusion reactions of β-cyclodextrin and its derivatives with cinnamaldehyde in Cinnamomum loureirii essential oil

Cyclodextrin and methacrylic acid octyl phenols poly(ethylene oxide) ester‐induced synergistic effect in a novel poly(AM‐co‐A‐β‐CD‐co‐AE) polymer

“…Formation of inclusion complexes due to the insertion of the hydrophobic portion of the guest molecule inside the apolar cavity can result in dramatic changes in the physico‐chemical properties of the guest molecule (such as increasing the their solubility and/or enhancing their stability, enhancing their absorbance or fluorescence intensity, and augmenting their bioavailability, etc.) 16–23, which have been reported by many researchers. Therefore, β‐CD has been widely approved to use in the food, cosmetics, textiles, and pharmaceutical industries.…”

“…Therefore, the cross‐linked structure and the enhancement of intermolecular interaction result in the increasing of viscosity. However, the inclusion process is exothermic 19, 20, so the viscosity due to dissociation of inclusion complexes decreases when the temperature rose. On the other hand, if the temperature continues to increase, the structure of the polymers chain will be changed or/and broken, which would result in a huge loss of polymer solution viscosity 32.…”

“…With their unique cavity of hydrophobic interior and polar or hydrophilic exterior, β‐CDs which have been widely utilized as universal additives, can form host–guest inclusion complexes with wide range of guest molecules such as various inorganic, organic, and biological compounds, etc. 15–23. Formation of inclusion complexes due to the insertion of the hydrophobic portion of the guest molecule inside the apolar cavity can result in dramatic changes in the physico‐chemical properties of the guest molecule (such as increasing the their solubility and/or enhancing their stability, enhancing their absorbance or fluorescence intensity, and augmenting their bioavailability, etc.)…”

Preparação e caracterização do complexo de inclusão do óleo essencial de Croton zehntneri com β-ciclodextrina

“…15 As ciclodextrinas são solúveis em água e possuem a capacidade de formar complexos de inclusão reversíveis com moléculas apolares, incrementando de forma exponencial sua solubilidade em meio aquoso. 12 Baseado nesta propriedade, diversos óleos essenciais e compostos voláteis passaram a ser complexados com ciclodextrinas, 13,14,[16][17][18][19][20][21][22] aumentando sua estabilidade, solubilidade aquosa, fotoestabilidade e estabilidade térmica, além de protegê-los da oxidação, mascarar ou reduzir efeitos fisiológicos indesejados, além de reduzir sua volatilidade. 15 Apesar do grande número de trabalhos desenvolvidos na linha de pesquisa de compostos de inclusão com CDs, a caracterização dos complexos constitui, ainda hoje, uma etapa delicada no processo de síntese.…”

Synthesis and characterization of a novel β-cyclodextrin modified cationic polyacrylamide and its application for enhancing oil recovery

“…Cyclodextrins (CDs) are cyclic oligosaccharides consisting of six to eight glucose units linked by 1,4-a-glucosidic bonds [1]. Of them, b-Cyclodextrin (b-CD) is a promising material widely used in many fields including biology [2], corrosion science [3], organic and polymer chemistry [4] since it can form host/guest complexes through complexation with suitable hydrophobic molecules [5][6][7]. Moreover, many researchers [8][9][10][11][12][13] have found that b-CDs can well maintain stability even under high temperature and/or salinity, which ensures its potential applications in the petroleum industry for complex oil reservoirs.…”
