Abstract
Abstract A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 0.1 to about 15% by weight, and tissue paper treated with such lotion compositions are disclosed. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, a solid polyol polyester immobilizing agent to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.
