Abstract

A styling device for hair, comprising protrusions, wherein the protrusions comprise a blend of a high molecular weight polyethylene oxide and a water insoluble polymer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A styling device for hair, comprising protrusions,
 wherein the protrusions comprise a blend of a high molecular weight polyethylene oxide and a water-insoluble polymer.   
     
     
         2 . The device of  claim 1 , wherein the polyethylene oxide has a molecular weight of at least about 50,000 daltons. 
     
     
         3 . The device of  claim 1 , wherein the polyethylene oxide has a molecular weight from about 100,000 to about 300,000 daltons. 
     
     
         4 . The device of  claim 1 , wherein the water insoluble polymer is selected from the group consisting of a polyolefin, polyactic acid, polyester, polyamides, polystyrene and combinations thereof. 
     
     
         5 . The device of  claim 1 , wherein the water insoluble polymer is polyethylene or polypropylene. 
     
     
         6 . The device of  claim 1 , wherein the blend of polyethylene oxide and water insoluble polymer is in a ratio from about 10:90 to about 80:20. 
     
     
         7 . The device of  claim 1 , wherein the blend of polyethylene oxide and water insoluble polymer is in a ratio from about 30:70 to about 50:50. 
     
     
         8 . The device of  claim 1 , wherein the protrusions are bristles or teeth. 
     
     
         9 . The device of  claim 1 , wherein the styling device is selected from the group consisting of a comb, a brush, a massager, a hair clip, a hair pick, a hair curler or a scrubber. 
     
     
         10 . The device of  claim 1 , wherein the styling device further comprises a handle. 
     
     
         11 . The device of  claim 1 , wherein the protrusions comprise at least one water soluble active in addition to the polyethylene oxide. 
     
     
         12 . The device of  claim 11 , wherein the water soluble active is selected from the group consisting of an anti-static active, a conditioning active, a friction reduction active, a lubrication active, an emollient, and combinations thereof. 
     
     
         13 . The device of  claim 1 , wherein the protrusions further comprise an additional high molecular weight material. 
     
     
         14 . The device of  claim 1 , wherein the device is a comb comprising 1 row of protrusions. 
     
     
         15 . The device of  claim 1 , wherein the device is a brush comprising more than 1 row of protrusions. 
     
     
         16 . The device of  claim 1 , wherein the device further comprises a motor for vibration of the protrusions. 
     
     
         17 . The device of  claim 1 , wherein the high molecular weight polyethylene oxide and water insoluble polymer are blended and co-extruded. 
     
     
         18 . A styling device for hair, comprising at least one flat surface, wherein at least one flat surface comprises a blend of a high molecular weight polyethylene oxide and a water insoluble polymer. 
     
     
         19 . The styling device of  claim 18 , wherein the device has two flat surfaces comprising a blend of a high molecular weight polyethylene oxide and a water insoluble polymer and the two flat surfaces are connected via a hinge, allowing the two flat surfaces to be pressed together. 
     
     
         20 . The styling device of  claim 19 , wherein the polyethylene oxide has a molecular weight from about 100,000 to about 300,000, and wherein the water insoluble polymer is polyethylene or polypropylene.
