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 a liquid polyol polyester emollient and an immobilizing agent to immobilize the liquid polyol polyester 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.
