Abstract
A soft tissue product includes deposits of a surface additive composition disposed in primary and supplementary delivery zones having different add-on levels. The supplementary add-on level is greater than 0 and less than the primary add-on level. For example, the supplementary add-on level may be from about 0.5 to about 80 percent of the primary add-on level. In particular embodiments, the primary delivery zones cover from about 30 to about 90 percent of the tissue and the supplementary delivery zones cover from about 10 to about 70 percent of the tissue. The different add-on levels effectively maximize consumer benefit while minimizing the total amount of additive on the tissue.
