Benefits of technology
[0015] The present invention is also directed to a deodorant or antiperspirant 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.
[0016] The present invention is additionally directed to a deodorant or antiperspirant composition comprising 1,3-propanediol wherein said 1,3-propanediol has a concentration of total organic impurities of less than about 400 ppm.
Problems solved by technology
It is a known fact, however, that vegetable glycerin formulas present several key challenges including stability and stickiness.
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.

Abstract
Disclosed herein are all natural or substantially natural deodorant and antiperspirant compositions comprising 1,3-propanediol wherein the 1,3-propanediol in said all natural or substantially natural deodorant or antiperspirant 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.
