Phosphorous-containing surfactants as polymeric cationic compound deposition aids

Abstract

Personal care products exhibiting superior conditioning and/or color fastness can be obtained by use of mixtures of certain phosphate esters and polyquats.

1 . A personal care product comprising:
 a) at least one polyquaternium compound having greater than 4 quaternary nitrogens in its structure and having a weight average molecular weight of between about 4,000 and about 2,000,000;   b) a mixture of alkoxylated and nonalkoxylated phosphate esters of fatty alcohols wherein the phosphate esters have a fatty alcohol based group having a chain length of between about C 8  and about C 22 , wherein the alkoxy groups comprise ethylene oxide, propylene oxide or mixtures thereof and about 1 to about 50 moles of alkylene oxide are used per mole of fatty alcohol based group, said alkoxylated and said nonalkoxylated phosphate esters being present in an amount such that no more than about 60% by weight of the phosphate esters are alkoxylated and wherein said alkoxylated and said nonalkoxylated phosphate esters comprise both mono- and diphosphate esters where the amount of diphosphate ester is at least about 40% by weight of the total amount of the said phosphate esters; and wherein the ratio of the phosphate ester to the polyquaternium compound is about 1.5:1 to about 100:1; and wherein a total amount of said phosphate esters and said polyquaternium compounds ranges from between about 0.20% to about 15% by weight of said personal care product, and   c) an additional ingredient.   
   
   
       2 . The personal care product of  claim 1 , wherein said alkoxylated and nonalkoxylated diphosphate esters are present in an amount equal to or greater than the amount of alkoxylated and nonalkoxylated monophosphate esters, and said nonalkoxylated phosphate esters are present in an amount equal to or greater than the amount of alkoxylated phosphate esters. 
   
   
       3 . The personal care product of  claim 1 , wherein the product is selected from the group consisting of a shampoo, conditioner, conditioning shampoo, body wash, cleanser, hair color and hair relaxer. 
   
   
       4 . The personal care product of  claim 1 , wherein the product is selected from the group consisting of a shampoo, conditioner, or conditioning shampoo for use in connection with synthetically colored hair. 
   
   
       5 . The personal care product of  claim 1 , wherein the product is a hair color. 
   
   
       6 . The personal care product of  claim 1 , wherein the product is a hair relaxer. 
   
   
       7 . The personal care product of  claim 1 , wherein the product is capable of reducing the wet combing force of a hair sample treated therewith by at least about 10 Joules relative to water. 
   
   
       8 . The personal care product of  claim 1 , wherein the product is capable of reducing the wet combing force of a hair sample treated therewith by at least about 20 Joules relative to water. 
   
   
       9 . The personal care product of  claim 7 , wherein the product is capable of reducing color change after fifteen washes relative to the same product without the phosphate esters and polyquaternium compounds of the invention. 
   
   
       10 . A personal care product comprising:
 a) a polyquaternium compound having 100 or more quaternary nitrogen groups and having a weight average molecular weight of between about 30,000 and about 1,000,000,   b) a nonalkoxylated phosphate ester of fatty alcohols wherein the phosphate esters have a fatty alcohol based group having a chain length of between about C 12  and about C 18 , wherein the ratio of the phosphate esters to the polyquaternium compound is 2:1 or greater, and wherein a total amount of the phosphate esters and the polyquaternium compounds range from between about 0.5% and about 5% by weight of the personal care product, and   c) an additional ingredient.   
   
   
       11 . The personal care product of  claim 10 , wherein said nonalkoxylated phosphate esters are present as a mixture of mono- and diphosphate esters where an amount of diphosphate esters greater than an amount of monophosphate esters. 
   
   
       12 . The personal care product of  claim 10 , wherein the product is selected from the group consisting of a shampoo, conditioner, conditioning shampoo, body wash, cleanser, hair color and hair relaxer. 
   
   
       13 . The personal care product of  claim 10 , wherein the product is selected from the group consisting of a shampoo, conditioner, or conditioning shampoo for use in connection with synthetically colored hair. 
   
   
       14 . The personal care product of  claim 10 , wherein the product is a hair color and wherein the ratio of the phosphate esters to the polyquaternium compound is 4:1 or greater. 
   
   
       15 . The personal care product of  claim 10 , wherein the product is a hair relaxer. 
   
   
       16 . The personal care product of  claim 10 , wherein the product is capable of reducing the wet combing force of a hair sample treated therewith by at least about 10 Joules relative to water. 
   
   
       17 . The personal care product of  claim 10 , wherein the product is capable of reducing the wet combing force of a hair sample treated therewith by at least about 20 Joules relative to water. 
   
   
       18 . The personal care product of  claim 16 , wherein the product is capable of reducing color change after fifteen washes relative to the same product without the phosphate esters and polyquaternium compounds of the invention.
