Abstract
Dry products, and particularly dry tissue substrates, including a blend of conventional papermaking fibers and microalgae are disclosed herein. Use of a cationic retention aid in the dry tissue substrates helps to provide a tissue sheet retaining the microalgae without being detrimental to tissue properties such as caliper, bulk, air permeability, slough and absorbent capacity. Additionally, use of a flocculating agent may agglomerate the microalgae and make it easier to retain the microalgae within the tissue sheet.
