Abstract

Disclosed herein are biodegradable coating and paint compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said biodegradable composition has a bio-based carbon content of about 1% to 100%. In addition, it is preferred that the 1,3-propanediol be biologically-derived, and wherein upon biodegradation, the biologically-derived 1,3-propanediol contributes no anthropogenic CO2 emissions to the atmosphere.

Claims

exact text as granted — not AI-modified
What is claimed: 
     
         1 . A biodegradable composition comprising 1,3-propanediol and an ingredient, wherein said 1,3-propanediol has a bio-based carbon content of at least 1%, wherein the bio-based carbon has a C-14/C-12 isotope ratio in range of from 1:0 to greater than 0:1, wherein said composition has a lower anthropogenic CO 2  emission profile as compared to a biodegradable composition comprising a 1,3-propanediol with a bio-based carbon content of 0% and wherein said composition is selected from the group consisting of coatings, paints, and inks. 
     
     
         2 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol makes up about 1% to about 50% of the composition by weight. 
     
     
         3 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 5% biobased carbon. 
     
     
         4 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 10% biobased carbon. 
     
     
         5 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 25% biobased carbon. 
     
     
         6 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 50% biobased carbon. 
     
     
         7 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 75% biobased carbon. 
     
     
         8 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 90% biobased carbon. 
     
     
         9 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has at least 99% biobased carbon. 
     
     
         10 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol has 100% biobased carbon. 
     
     
         11 . The biodegradable composition of  claim 1  wherein the 1,3-propanediol is biologically-derived. 
     
     
         12 . The biodegradable composition of  claim 11  wherein the biologically-derived 1,3-propanediol is biologically produced through a fermentation process. 
     
     
         13 . A biodegradable composition comprising 1,3-propanediol wherein said 1,3-propanediol has an ultraviolet absorption at 220 nm of less than about 0.200 and at 250 nm of less than about 0.075 and at 275 nm of less than about 0.075, wherein the composition comprises bio-based carbon having a C-14/C-12 isotope ratio in range of from 1:0 to greater than 0:1, and wherein said composition has a lower anthropogenic CO 2  emission profile as compared to a biodegradable composition comprising a 1,3-propanediol with a bio-based carbon content of 0%, wherein said composition is selected from the group consisting of coatings, paints, and inks. 
     
     
         14 . The biodegradable composition of  claim 13  wherein the 1,3-propanediol makes up about 1% to about 50% of the composition by weight. 
     
     
         15 . The biodegradable composition of  claim 13  wherein said 1,3-propanediol has a “b” color value of less than about 0.15 and an absorbance at 275 nm of less than about 0.050. 
     
     
         16 . The biodegradable composition of  claim 13  wherein said 1,3-propanediol has a peroxide concentration of less than about 10 ppm. 
     
     
         17 . The biodegradable composition of  claim 13  wherein said 1,3-propanediol has a concentration of total organic impurities in said composition of less than about 400 ppm. 
     
     
         18 . The biodegradable composition of  claim 13  wherein said 1,3-propanediol has a concentration of total organic impurities of less than about 300 ppm. 
     
     
         19 . The biodegradable composition of  claim 13  wherein said 1,3-propanediol has a concentration of total organic impurities of less than about 150 ppm. 
     
     
         20 . The biodegradable composition of  claim 13  wherein said 1,3-propanediol has a concentration of carbonyl groups of less than about 10 ppm.
