Abstract

The invention relates to wax-based opacifier preparations containing (a) at least one amphoteric surfactant, (b) at least one fatty acid partial glyceride, (c) at least one fatty acid polyglycol ester and optionally (d) a polyol, with the proviso that the ratio by weight of (a) to (b) is between 10:1 and 4:1 and the ratio by weight of (b) to (c) is between 1:1 and 5:1 and the preparations are free from anionic surfactants.

Claims

exact text as granted — not AI-modified
1 - 13 . (cancelled).  
     
     
         14 . An opacifier composition comprising: 
 (a) an amphoteric surfactant;    (b) a fatty acid partial glyceride;    (c) a fatty acid polyglycol ester;    (d) a wax component; and    (e) optionally, up to about 10% by weight of a polyol, and wherein (a) and (b) are present in the composition in a ratio by weight of from about 10:1 to 4:1, and (b) and (c) are present in the composition in a ratio by weight of from about 1:1 to 5:1.    
     
     
         15 . The composition of  claim 14  wherein (a) and (b) are present in the composition in a ratio by weight of from about 7:1 to 5:1, and (b) and (c) are present in the composition in a ratio by weight of from about 2:1 to 4:1.  
     
     
         16 . The composition of  claim 14  wherein (a) is present in the composition in an amount of from about 1 to 25% by weight, based on the weight of the composition.  
     
     
         17 . The composition of  claim 14  wherein (b) is present in the composition in an amount of from about 0.1 to 6% by weight, based on the weight of the composition.  
     
     
         18 . The composition of  claim 14  wherein (c) is present in the composition in an amount of from about 0.1 to 6% by weight, based on the weight of the composition.  
     
     
         19 . The composition of  claim 14  wherein (d) is present in the composition in an amount of from about 10 to 35% by weight, based on the weight of the composition.  
     
     
         20 . The composition of  claim 14  wherein the composition has a solids content of from about 20 to 50% by weight, based on the weight of the composition.  
     
     
         21 . The composition of  claim 14  wherein the composition has a viscosity of from about 2,000 to 6,000 mPas.  
     
     
         22 . The composition of  claim 14  wherein the composition has a particle size distribution such that at least 85% of the particles contained therein have a diameter of less than 15 μm.  
     
     
         23 . The composition of  claim 14  wherein particles present in the composition have a mean particle diameter of less than 12 μm.  
     
     
         24 . A process for making an opaque composition comprising: 
 (a) providing an amphoteric surfactant;    (b) providing a fatty acid partial glyceride;    (c) providing a fatty acid polyglycol ester;    (d) providing a wax component;    (e) providing, optionally, up to about 10% by weight of a polyol; and    (f) mixing (a)-(e) to form the composition, and wherein (a) and (b) are present in the composition in a ratio by weight of from about 10:1 to 4:1, and (b) and (c) are present in the composition in a ratio by weight of from about 1:1 to 5:1.    
     
     
         25 . The process of  claim 24  wherein (a) and (b) are present in the composition in a ratio by weight of from about 7:1 to 5:1, and (b) and (c) are present in the composition in a ratio by weight of from about 2:1 to 4:1.  
     
     
         26 . The process of  claim 24  wherein (a) is present in the composition in an amount of from about 1 to 25% by weight, based on the weight of the composition.  
     
     
         27 . The process of  claim 24  wherein (b) is present in the composition in an amount of from about 0.1 to 6% by weight, based on the weight of the composition.  
     
     
         28 . The process of  claim 24  wherein (c) is present in the composition in an amount of from about 0.1 to 6% by weight, based on the weight of the composition.  
     
     
         29 . The process of  claim 24  wherein (d) is present in the composition in an amount of from about 10 to 35% by weight, based on the weight of the composition.  
     
     
         30 . The process of  claim 24  wherein the composition has a solids content of from about 20 to 50% by weight, based on the weight of the composition.  
     
     
         31 . The process of  claim 24  wherein the composition has a viscosity of from about 2,000 to 6,000 mpas.  
     
     
         32 . The process of  claim 24  wherein the composition has a particle size distribution such that at least 85% of the particles contained therein have a diameter of less than 15 μm.  
     
     
         33 . The process of  claim 24  wherein particles present in the composition have a mean particle diameter of less than 12 μm.
