| Abstract | The rheological properties describe flow behavior of film-forming solutions and may predict the film properties. Thus,the relationship was studied between the rheological properties and the hydroxypropyl methylcellulose (HPMC) film properties.HPMC solutions of glycerol, beeswax (BW) and stearic acid with two essential oils (EOs; ginger oil and plai oil) were measuredfor their steady shear responses and dynamic viscoelasticity before forming the films. The flow behavior of the HPMC solutionwith BW and EOs was shear-thinning non-Newtonian. Moreover, all the HPMC solutions had higher values for the loss modulus(Gโ) than for the elastic modulus (Gโ). The Gโ and Gโ values of film-forming solutions with BW and EOs correlated well withthe mechanical properties of the films. Furthermore, film water vapor permeability was negatively correlated with the mechanicalproperties of the film. |
