Abstract
The present disclosure relates to a personal care device having a conditioning layer comprising a porous matrix comprising pores and having a hydrophobic conditioning agent fluid dispersed in the pores so that the conditioning agent can migrate to an exposed surface of the conditioning layer and then may be transferred to hair or skin surfaces. The conditioning layer may be prepared by preparing an immiscible conditioning composition comprising a hydrophilic material that is capable of being cured, and a hydrophobic conditioning agent. The immiscible composition is cured to form a conditioning layer that is a porous matrix formed from the hydrophilic material, the porous matrix having the hydrophobic conditioning agent fluid dispersed in the pores thereof.
