Abstract
Methods and compositions for preparing multilayer nail coatings that enable facile removal of nail enhancements formed thereon are described herein. The nail enhancements become removable upon exposure to a suitable removal stimulus.
Claims38
A method of forming a multilayer nail coating and a nail enhancement thereon comprising the steps of:
- (a) applying a nail primer layer to the nail;
- (b) contacting the nail primer layer with a nail powder composition to form a nail powder layer thereon;
- (c) optionally removing any excess of the nail powder composition, such as by tapping, brushing, wiping, and/or other physical means, from the coated nail;
- (d) optionally exposing the nail primer layer coated with the nail powder layer to a stimulus, such as light or heat, for a sufficient period of time to induce at least partial curing of the nail primer layer;
- (e) applying one or more nail products to the multilayer nail coating formed from steps (a)-(d) to form the nail enhancement thereon;
- wherein the nail powder composition comprises:
- a plurality of particles wherein at least a portion of the particles can undergo a phase and/or shape transition upon exposure to a removal stimulus, such as a thermal stimulus, an electromagnetic stimulus, or a combination thereof.

A nail powder composition comprising:
- a plurality of particles wherein at least a portion of the particles can undergo a phase and/or shape transition upon exposure to a removal stimulus, such as a thermal stimulus, an electromagnetic stimulus, or a combination thereof;
- and
- one or more primary additives that improve performance, such as improved adhesion to a nail primer layer and/or adhesion to a nail product, increase shape and/or volume change of the particles of the plurality when exposed to the removal stimulus, and/or reduce damage to the multilayer nail coating when applying additional layers of a nail primer or a nail product over a nail powder layer formed from the nail powder composition.
