AI Technical Summary

Benefits of technology

"The present invention is about a personal care or cosmetic product that contains 1,3-propanediol and a carrier. The 1,3-propanediol has a minimum of 1% bio-based carbon content. The product also has low ultraviolet absorption and is free of organic impurities. Additionally, the 1,3-propanediol has a zero anthropogenic CO2 emission profile when biodegraded."

Problems solved by technology

While biodegradability is an important factor in protecting the environment, biodegradation of glycols derived from fossil-based sources has the unavoidable consequence of releasing previously fixed CO2 into the atmosphere.

[0203] Phase A was combined at 75° C. Phase B was combined at 75° C. Phase B was added to Phase A. Phase C was then added to the Phase A / B. Phase A / B / C was cooled to 40° C. and then Phase D was added. pH was adjusted to 7.0-7.5 with Phase C. The formulation produced was a smooth white and apparently stable emulsion.

[0204] RESULTS—pH 7.38, viscosity 12000 cps at 20 RPM

[0205] Oven stability was examined. Results were deemed acceptable.

[0206] Freeze / thaw stability was also examined. Freeze / thaw stability was deemed acceptable.

Abstract

Disclosed herein are personal care and cosmetic compositions comprising 1,3-propanediol, wherein the 1,3-propanediol in said personal care or cosmetic 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.
