Abstract
Strong, soft, absorbent tissue paper products comprising a substrate carrying an emollient. The substrate is planar and is a laminate formed of two or more tissue paper sheets. At least one of its two major surfaces must be soft, relatively untextured, and smooth. The emollient is distributed over at least a major portion of the smooth surface. In preferred embodiments, each tissue paper ply consists of two layers: the first is relatively weak compared to the second and has an outwardly facing surface which is soft, relatively untextured and smooth; the second layer is strong enough to impart to the ply sufficient strength to enable it to accomplish its intended purpose. The plies of tissue paper are joined together by a laminating means consisting of embossments in a region of embossing; the region of embossing is substantially free of emollient.
