<p>Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include diester di(oleyl)dimethyl ammonium chloride (DEDODMAC) (i.e., di(octadec-z-9-eneoyloxyethyl)dimethyl) ammonium chloride) derived from canola oil and/or high oleic safflower oil. Variables that need to be adjusted to maximize the fluidity of vegetable oil based acyl groups include the cis/transisomer ratio or the lodine Value (IV) of the fatty acyl groups. The tissue softness is further enhanced by controlling the purity of the fatty acyl groups and the di-substituted versus mono-substituted long chain hydrocarbyl substitutent ratio in the quaternary ammonium compounds.</p> |
