摘要:
The invention provides a cream comprising non-spherical nanoparticles, a method of manufacture of a cream with changeable visual properties (e.g. colour, lustre, and/or iridescence); and a method of controlling the visual appearance of a cream by exposing the cream to an electric field. The non-spherical nanoparticles may be nano-rods, and the method of altering the visual appearance of the cream comprises the steps of embedding nanoparticles in a cream, forming a film of the cream having a first visual appearance, and exposing the film to an electric field to rotate the nanoparticles and transform the cream from a first visual appearance to a second altered visual appearance. The application of the electric field cause the rotation of the nanoparticle such that they become substantially aligned relative to one another. The invention relates to the field of cosmetic creams.
