Abstract

An excellent moisturizer, hyaluronic acid (HA(, provides biocompatibility and viscoelastic properties that is extensively utilized in cosmetics. High molecular weight HA (HMW-HA, 1.2 MDa( is a typical used form, however its benefits is limited due to its large molecule. In our previous study, the association with quaternized cyclodextrin grafted chitosan (QCD-g-CS( can improve skin penetration and provide positive charge promoting skin adhesion. Thus, the purpose of this study was to produce and characterize HMW-HA associated QCD-g-CS nanoparticles for cosmetic utilization. The HMW-HA nanoparticles (0.01 HA per 1 QCD-g-CS mole ratio( was the best formula with low particles size (348.20 ± 8.67 nm(, narrow polydispersity index (0.083 ± 0.02(and positive zeta potential (16.00 ± 0.36 mV(. The association efficiency and loading efficiency were analyzed by UPLC and shown to be 82.64 ± 0.39% and 20.09 ± 0.57%, respectively. The conjugation between carboxylic moieties of HMW-HA and amide of QCD-g-CS was confirmed by FTIR. The TEM imaging showed the spherical morphology of these nanoparticles. According to cytotoxicity test, these nanoparticles (0.01 to 0.10 mg/ml( were safe in human skin fibroblasts.

Abstract

Inclusion of the two isomers of citral (E-citral andZ-citral), components of lemongrass oil, was investigated within the confines of various cyclodextrin (?-CD,?-CD and?-CD) host molecules. Aqueous complex formation constants forE-citral with?-CD,?-CD and?-CD were determined to be 123, 185, and 204 L/mol, respectively, whereasZ-citral exhibited stronger affinities (157, 206, and 253 L/mol, respectively). The binding trend?-CD > ?-CD > ?-CD is a reflection of the more favorable geometrical accommodation of the citral isomers with increasing cavity size. Encapsulation of lemongrass oil within CDs was undertaken through shaking citral:CD (1:1, 1.5:1, and 2:1 molar ratio) mixtures followed by spray drying. Maximum citral retention occurred at a 1:1 molar ratio with?-CD and?-CD demonstrating the highest levels of totalE-citral andZ-citral retention, respectively. Furthermore, the?-CD complex demonstrated the slowest release rate of all inclusion complex powders. The inclusion between two isomers of citral (E-citral andZ-citral) in lemongrass oil and cyclodextrins by spray drying were studied. [ABSTRACT FROM PUBLISHER]
