Abstract

This invention provides a non-disposable, environmentally friendly toothbrush comprising a solid handle and bristled filaments operably affixed thereto, wherein the solid handle is made of an environmentally friendly composition of matter comprising an admixture of cornstarch (PSM) and recycled polypropylene, the weight ratio of biodegradable cornstarch (PSM) to recycled polypropylene being from 50:50 to 80:20.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A toothbrush comprising a solid handle and bristled filaments operably affixed thereto, wherein the solid handle is made of a composition of matter comprising an admixture of biodegradable cornstarch (PSM) and recycled polypropylene, the weight ratio of cornstarch (PSM) to recycled polypropylene being from 50:50 to 80:20. 
     
     
         2 . The toothbrush of  claim 1 , wherein the weight ratio of cornstarch (PSM) to recycled polypropylene is from 50:50 to 75:25. 
     
     
         3 . The toothbrush of  claim 1 , wherein the weight ratio of cornstarch (PSM) to recycled polypropylene is 65:35. 
     
     
         4 . The toothbrush of  claim 1 , wherein the solid handle is made of a composition of matter consisting of an admixture of biodegradable cornstarch (PSM) and recycled polypropylene, the weight ratio of cornstarch (PSM) to polypropylene being from 50:50 to 80:20. 
     
     
         5 . The toothbrush of  claim 4 , wherein the weight ratio of cornstarch (PSM) to recycled polypropylene is from 50:50 to 75:25. 
     
     
         6 . The toothbrush of  claim 4 , wherein the weight ratio of cornstarch (PSM) to recycled polypropylene is 65:35. 
     
     
         7 . A method for making a solid composition of matter suitable for use as a toothbrush handle comprising the step of admixing biodegradable cornstarch (PSM) and recycled polypropylene under suitable conditions, wherein the weight ratio of cornstarch (PSM) to polypropylene is from 50:50 to 80:20. 
     
     
         8 . The method of  claim 7 , wherein the weight ratio of cornstarch (PSM) to recycled polypropylene is from 50:50 to 75:25. 
     
     
         9 . The method of  claim 7 , wherein the weight ratio of cornstarch (PSM) to recycled polypropylene is 65:35.
