A nail polish or lacquer removing composition is provided that includes a volatile organic solvent such as acetone, gelatin and glycerin present to stably suspend the gelatin in the solvent.

A composition useful for removing nail lacquer is disclosed. This composition comprises an aqueous solution of a chelating agent, a humectant such as an alkylene glycol, a 2-hydroxy-4-methoxy-benzophenone-5-sulfonic acid, a proteinaceous material and vitamin A and D palmitates, the aforesaid ingredients being dispersed in a thickened acetone vehicle to form a homogeneous creamy stable mixture.

An aqueous acetone-based nail polish remover comprises: i. from 40 to 90% by weight acetone, and ii. from 0.001 to 10% by weight of hydrolyzed keratin.

A method for behavior modification using olfactory stimuli. The method comprises microencapsulating different smelling odors into a patch such that at least one odor is dominant and at least one odor is subservient, placing the patch on a hand associated with the behavior to be modified, scratching the patch when the urge to engage in the behavior to be modified occurs, thereby temporarily releasing the subsurvient odor, smelling the patch with the released subservient odor to act as a stimulus to effect behavior modification, and smelling the patch after the urge to engage in the behavior to be modified passes thereby reinforcing the behavior modification with the dominant odor.

A pressure-sensitive microcapsule-containing composition composed of a liquid phase capable of solidification which has substantially evenly dispersed therethroughout a multiplicity of microencapsulated droplets of a solvent phase. The shells of the microcapsule are rupturable under applied pressure for selectively releasing the solvent phase for dissolving the liquid phase after it has solidified.
