Abstract

A mild cleansing composition that produces a stable foam containing at least one glycoside nonionic surfactant; at least one betaine surfactant; and at least one amphoteric surfactant, is disclosed. The composition is substantially free of anionic surfactant.

Claims

exact text as granted — not AI-modified
We claim:  
     
         1 . A cleansing composition comprising: 
 at least one glycoside nonionic surfactant;    at least one betaine surfactant; and    at least one amphoteric surfactant, wherein the composition is substantially free of anionic surfactants.    
     
     
         2 . The composition of  claim 1  wherein the composition possesses a low degree of ocular irritancy and yields a long-lasting stable foam.  
     
     
         3 . The composition according to  claim 1  wherein the glycoside nonionic surfactant is selected from coco glucoside, octyl glucoside, decyl glucoside, lauryl glucoside, and mixtures thereof.  
     
     
         4 . The composition according to  claim 3  wherein the amount of glycoside non ionic surfactant ranges from about 0.1% to about 20% by weight, based on the total weight of the composition.  
     
     
         5 . The composition according to  claim 3  wherein the amount of glycoside non ionic surfactant ranges from about 0.5% to about 15% by weight, based on the total weight of the composition.  
     
     
         6 . The composition according to  claim 3  wherein the amount of glycoside nonionic surfactant ranges from about 1% to about 10% by weight, based on the total weight of the composition.  
     
     
         7 . The composition according to  claim 1  wherein the betaine surfactant is selected from the group consisting of alkyl betaines, alkyl sultaines, amidoalkyl betaines, amidoalkylsultaine, and mixtures thereof, wherein the alkyl group contains from about C 8  to about C 22  carbon atoms.  
     
     
         8 . The composition according to  claim 7  wherein the betaine surfactant is decyl betaine, lauryl hydroxysultane, oleamidopropylhydroxysultaine, cocamidopropylbetaine, and mixtures thereof.  
     
     
         9 . The composition according to  claim 7  wherein the amount of betaine surfactant ranges from about 0.1% to about 20% by weight, based on the total weight of the composition.  
     
     
         10 . The composition according to  claim 7  wherein the amount of betaine surfactant ranges from about 0.5% to about 15% by weight, based on the total weight of the composition.  
     
     
         11 . The composition according to  claim 1  wherein the amphoteric surfactant is selected from the group consisting of amphocarboxylates, alkylamidoalkylamines, alkyl substituted amino acids, amphophosphates, carboxyalkyl alkyl polyamines, and mixtures thereof, wherein the alkyl group contains from about C 8  to about C 22  carbon atoms.  
     
     
         12 . The composition according to  claim 11 , wherein the amphoteric surfactants are selected from the group consisting of lauroamphodiacetate, lauriminodipropionate, cocoamphopropionate, lauroamphodipropionic acid, capryloamphohydroxypropylsulfonate, and mixtures thereof.  
     
     
         13 . The composition according to  claim 11  wherein the amount of amphoteric surfactant ranges from about 0.1% to about 20% by weight, based on the total weight of the composition.  
     
     
         14 . The composition according to  claim 11  wherein the amount of amphoteric surfactant ranges from about 0.5% to about 15% by weight, based on the total weight of the composition.  
     
     
         15 . The composition according to  claim 13  wherein the amount of amphoteric surfactant ranges from about 1% to about 10% by weight, based on the total weight of the composition.  
     
     
         16 . The composition according to  claim 1  wherein the glycoside nonionic surfactant is decyl glucoside and ranges from about 1% to about 10% by weight, based on the total weight of the composition; the betaine surfactant is cocamidopropylbetaine and ranges from about 1% to about 10% by weight, based on the total weight of the composition; and the amphoteric surfactant is lauroamphodiacetate and ranges from about 1% to about 10% by weight, based on the total weight of the composition.  
     
     
         17 . The composition according to  claim 1  wherein the ratio of the glycoside nonionic surfactant to the sum of the amounts of the amphoteric surfactant and the betaine surfactant ranges from about 1 to 4 to about 1.5 to 1.  
     
     
         18 . The composition according to  claim 1  wherein the ratio of the amount of the betaine surfactant to the amount of the amphoteric surfactant ranges from about 1 to 2 to about 10 to 1.
