Abstract:
A soft tissue paper product, said soft tissue paper product comprising:a. one or more plies of a tissue paper; and b. a chemical softening composition deposited on at least one outer surface of a dried or overdried tissue web, said chemical softening composition comprising: i. from about 10% to about 50%, based on the weight of the chemical softening composition, of a softening active ingredient, wherein said softening active ingredient comprises a quaternary ammonium compound, selected from the group of quaternary ammonium compounds having the formulas: (R1)4âˆ’mâ€”N+â€”[R2]mXâˆ’â€ƒâ€ƒA) â€ƒwherein: m is 1 to 3; each R1 is a C1-C6 alkyl or alkenyl group, hydroxyalkyl group, hydrocarbyl or substituted hydrocarbyl group, alkoxylated group, benzyl group, or mixtures thereof; each R2 is a C14-C22 alkyl or alkenyl group, hydroxyalkyl group, hydrocarbyl or substituted hydrocarbyl group, alkoxylated group, benzyl group, or mixtures thereof; and Xâˆ’ is any softener-compatible anion; (R1)4âˆ’mâ€”N+â€”[(CH2)nâ€”Yâ€”R3]mXâˆ’â€ƒâ€ƒB) â€ƒwherein Y is â€”Oâ€”(O)Câ€”, or â€”C(O)â€”Oâ€”, or â€”NHâ€”C(O)â€”, or â€”C(O)â€”NHâ€”; m is 1 to 3; n is 0 to 4; each R1 is a C1-C6 alkyl or alkenyl group, hydroxyalkyl group, hydrocarbyl or substituted hydrocarbyl group, alkoxylated group, benzyl group, or mixtures thereof; each R3 is a C13-C21 alkyl or alkenyl group, hydroxyalkyl group, hydrocarbyl or substituted hydrocarbyl group, alkoxylated group, benzyl group, or mixtures thereof; and Xâˆ’ is any softener-compatible anion; â€ƒwherein each R1 is a C1-C6 alkyl or hydroxyalkyl group, each R3 is an C1-C21 hydrocarbyl group, n is 2 to 4 and Xâˆ’ is any softener compatible anion; and D) mixtures thereof; ii. from about 0.1% to about 25%, based on the weight of the chemical softening composition, of an electrolyte; and iii. from about 0.1% to about 7.5%, based on the weight of the chemical softening composition, of a bilayer disrupter.
