Key Points

The aim is to assess the friction dynamics of amorphous rice starch in powder, dispersion, and dried film forms.
Evaluated friction dynamics of crystalline and amorphous rice starch in multiple states.
Analyzed the impact of amorphization on the coefficient of friction.
Investigation included the influence of composition with water and glycerin.
Amorphous rice starch increased the coefficient of friction across all states assessed.
Transition to flake-like structure improved liquid retention capacity.
High viscosity mixtures formed under various conditions indicate potential for skin coating applications.

Implication

Evaluates friction dynamics of amorphous rice starch in various states, suggesting potential applications for skin coatings.
