Tissue Paper Comprising a Softening Lotion

Abstract

The present invention relates to a tissue paper comprising a lotion composition, said lotion being a liquid water-in-oil emulsion comprising (A) a hydrocarbon-based oil, (B) optionally at least one further oil, (C) 3 to 40 weight % of at least one non-ionic water-in-oil emulsifier, (D) 0.5 to 10 weight % of at least one coemulsifier based on an ethylene oxide-modified glyceride, (E) optionally 1 to 15 weight % of at least one humectant, (F) optionally up to 10 weight % of a metal soap, and (G) 6 to 35 weight % of water, wherein the weight % values relate to the total weight of the lotion composition. The lotioned tissue paper of the invention is very stable, shows excellent softness properties and is capable of efficiently transferring lotion to the skin of the user. Moreover, the lotion can be applied at relatively low temperatures and does not adversely affect the whiteness degree of the tissue paper.

     wherein the weight % is based on the lotion composition. 
   
   
       2 . The tissue paper according to  claim 1 , wherein said oil component (A) comprises mineral oil. 
   
   
       3 . The tissue paper according to  claim 1 , wherein said lotion composition comprises at least one oil (B) having a viscosity of about 1 to about 100 mPa·s measured with a Höppler falling sphere viscosimeter at 20° C. (method DGF C-IV 7). 
   
   
       4 . The tissue paper according to  claim 1 , wherein said oil component (B) is selected from the group consisting of liquid synthetic triglyceride mixtures; vegetable oils; guerbet alcohols; liquid esters; liquid substituted cyclohexanes; symmetric or asymmetric dialk(en)ylethers having from 6 to 22 carbon atoms per alk(en)yl group; linear or branched dialk(en)ylcarbonates derived from C6 to C22 fatty alcohols; ring-opening products of epoxidized fatty acid esters and polyols; and silicone oils. 
   
   
       5 . The tissue paper according to  claim 1 , wherein said non-ionic emulsifier (C) comprises a liquid polyol polyester wherein a polyhydric alcohol having at least two hydroxy groups is esterified with at least one acid having from 6 to 30 carbon atoms. 
   
   
       6 . The tissue paper according to  claim 5 , wherein said polyol polyester comprises polyglycerin-2-dipolyhydroxystearate. 
   
   
       7 . The tissue paper according to  claim 1 , wherein the glyceride component of coemulsifier (D) comprises a hydroxy-fatty acid. 
   
   
       8 . The tissue paper according to  claim 1 , wherein said ethylene oxide-modified glyceride is obtained by reacting 2 to 15 mol of ethylene oxide per mol of glyceride. 
   
   
       9 . The tissue paper according to  claim 1 , wherein said coemulsifier (D) comprises ethylene oxide-modified hydrogenated castor oil. 
   
   
       10 . The tissue paper according to  claim 1 , wherein said humectant comprises glycerol. 
   
   
       11 . A tissue paper comprising a lotion composition, wherein said lotion composition is a water-in-oil emulsion comprising:
 (A) 25 to 35 weight % mineral oil,   (B) 20 to 30 weight % of a further oil component selected from the group consisting of liquid synthetic triglyceride mixtures; vegetable oils; guerbet alcohols; liquid esters; liquid substituted cyclohexanes; symmetric or asymmetric dialk(en)ylethers having from 6 to 22 carbon atoms per alk(en)yl group; linear or branched dialk(en)ylcarbonate derived from C6 to C22 fatty alcohols; ring-opening products of epoxidized fatty acid esters and polyols; and silicone oils;   (C) 12 to 21 weight % of a W/O emulsifier selected from liquid polyol polyester wherein a polyhydric alcohol having at least two hydroxy groups is esterified with at least one acid having from 6 to 30 carbon atoms,   (D) 4 to 7 weight % coemulsifier based on a glyceride comprising a hydroxy fatty acid being modified with the adduct of 2 to 15 mol ethylene oxide,   (E) optionally 1 to 10 weight % of at least one humectant,   (F) optionally 0.5 to 5 weight % of a metal soap   (G) 10 to 30 weight % water,   (H) optionally 0.1 to 5 weight % additives,   
     wherein the weight % is based on the lotion composition. 
   
   
       12 . A process for preparing a softened tissue paper comprising applying the lotion composition of  claim 1  to a tissue paper web. 
   
   
       13 . The process according to  claim 12 , wherein said lotion composition is applied at a temperature in the range of from about 25 to about 50° C. to the tissue paper web. 
   
   
       14 . A process for preparing a softened tissue paper, comprising applying the lotion composition of  claim 11  to a tissue paper web. 
   
   
       15 . The process according to  claim 14 , wherein said lotion composition is applied at a temperature in the range of from about 25 to about 50° C. to the tissue paper web.
