Abstract
A makeup remover pad is provided which comprises a resilient, open-celled hydrophilic foam matrix, wherein said matrix integrally incorporates an aqueous phase incorporating about 25-75% water, about 15-70% of a water-insoluble emollient oil, and an amount of surfactant effective to stabilize the aqueous phase so that it is released from the foam matrix as a homogeneous emulsion when the pad is applied to skin.
