Abstract: The present invention provides a nanoparticle comprising a poly(alkyl cyanoacrylate) homopolymer, or copolymer, at least one active agent and an anionic and radical inhibitor, wherein the anionic and radical inhibitor is a compound having the following formula: wherein R1 is H; and R3, R4, R5, R6 and R7 are independently selected from the group consisting of —H, —OH, C1-C6 alkoxide, C1-C6 alkyl, halides, carboxylic acid, ketone or aldehyde; wherein the anionic and radical inhibitor is present in an amount of 0.001 to 15 wt %, as well as a process suitable for manufacture of the nanoparticle.

Abstract: A hair care appliance for application of vapor to dry hair to provide humidity to the hair, including a housing defining an inner cavity, a vapor-generating system positioned at least partially within the cavity, and a spacer including a cap, a plurality of spacer elements projecting outwardly from the cap, and an aperture through the cap. The spacer elements partially define therebetween a work area in which the hair is gathered. The vapor-generating system discharges vapor through the aperture to the work area for application to the hair.

Abstract: A hair care appliance for application of vapor to dry hair including a housing having a head portion and a handle portion, the housing defining an inner cavity. A vapor-generating system is positioned at least partially within the cavity, and the head portion includes an aperture in communication with the vapor-generating system. A spacer is positioned proximate the aperture of the head portion and partially defines a work area for positioned hair, wherein the vapor-generating system discharges vapor to the work area for application to hair positioned thereby.
