Using the Spectrum Descriptive Analysis method, the present work defines a methodology developed in order to discriminate and characterize cosmetic oil-in-water emulsions as well as their respective aqueous phases containing xanthan gum. The objective was to describe and understand how composition parameters govern texture perception, through the study of the impact of the amount of (1) xanthan and...
Filament stretchability of xanthan gum (XG) and hydroxypropyl guar (HPG) was investigated in aqueous solutions (0.125, 0.25, 0.5, 1, 1.2 and 1.5% w/w) and in O/W emulsions using a texture analyzer. Additionally, rheological characterizations were carried out on the systems and shear and oscillation parameters were used to interpret stretching properties. XG solutions exhibited a solid-like behavior...
