FIELD OF THE INVENTION [0002] 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 CO.sub.2 emissions to the atmosphere. BACKGROUND OF THE INVENTION [0003] Perspiration produced in the apocrine sweat glands of the armpits (axilla) contains proteins and fatty acids. While initially odorless, this sweat becomes malodorous when bacteria on the skin and hair metabolize the proteins and fatty acids. The problem of odoriferous sweat breakdown products is generally addressed in two ways by personal care products--antiperspirancy and deodorancy. [0004] Antiperspirancy commonly is achieved by topically applying a composition containing a metal salt, such as an astringent aluminum or aluminum/zirconium salt. An influx of aluminum ions into secretory coil cells of human sweat glands are accompanied by an influx of water, causing the sweat gland cells to swell, squeezing the sweat ducts closed, and stopping perspiration. [0005] Deodorants function in several ways. Some mask the odor from bacterial breakdown products; others react with the bacterial and/or their byproducts that cause odor. Still others achieve deodorancy by inhibiting bacterial growth. [0006] Most deodorant products currently on the market contain synthetic carbon based glycol. Indeed even an estimated 50% of deodorant products claimed to be natural still contain synthetic non-bio based glycol and may often contain synthetic antibacterial agents to help kill the bacteria that cause odor. Vegetable glycerin based deodorant formulations are on the rise and now represent approximately 50% of the "natural" deodorant stick category. It is a known fact, however, that vegetable glycerin formulas present several key challenges including stability and stickiness. In order to stabilize glycerin formulas, often at least one, and more often several, man-made, synthetic chemical ingredient are used. Stickiness is a key detergent for consumers, and one of the main reasons this type of product hasn't penetrated the marketplace. [0007] Consumers of deodorants and antiperspirants consider many factors in selecting products for use. Recently certain factors have been a focus of and have driven scientific study and product development. These driving factors include, product safety, environmental impact, the extent to which the components are natural, and the aesthetic quality of the overall product. Therefore, manufacturers have to be concerned with the environmental impact of their products. In fact, the effort towards environmental impact awareness is a universal concern, recognized by government agencies. The Kyoto Protocol amendment to the United Nations Framework Convention on Climate Change (UNFCCC) currently signed by 156 nations is one example of a global effort to favor safer environmental manufacturing over cost and efficiency. When applied to deodorants and antiperspirants, consumers are increasingly selective about the origins of the products they purchase. The 2004 Co-operative Bank's annual Ethical Consumerism Report (www.co-operativebank.co.uk) disclosed a 30.3% increase in consumer spending on ethical retail products (a general classification for environmental safe, organic and fair trade goods) between 2003 and 2004 while total consumer spending during the same period rose only 3.7%. [0008] Glycols such as ethylene glycol, propylene glycol, 1,3-butylene glycol, and 2-methyl-1,3-propanediol are biodegradable compounds useful in compositions ranging from cosmetics and personal care formulations to detergents to heat transfer compositions. 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. Thus, while glycols in general are advantageous for their biodegradability, the resulting global warming potential of fossil-based glycols during biodegradation is significant. [0009] Carbon dioxide is singled out as the largest component of the collection of greenhouse gases in the atmosphere. The level of atmospheric carbon dioxide has increased 50% in the last two hundred years. Recent reports indicate that the current level of atmospheric carbon dioxide is higher than the peak level in the late Pleistocene, the epoch before modern humans (Siegenthaler, U. et al. Stable Carbon Cycle-Climate Relationship During the Late Pleistocene, Science, Vol. 310, no. 5752 (Nov. 25, 2005), pp. 1313-1317). Therefore, any further addition of carbon dioxide to the atmosphere is thought to further shift the effect of greenhouse gases from stabilization of global temperatures to that of heating. Consumers and environmental protection groups alike have identified industrial release of carbon into the atmosphere as the source of carbon causing the greenhouse effect. [0010] Greenhouse gas emission can occur at any point during the lifetime of a product. Consumers and environmental groups consider the full lifespan of a product when evaluating a product's environmental impact. Consumers look for products that do not contribute new carbon to the atmosphere considering the environmental impact of production, use and degradation. Only organic products composed of carbon molecules from plant sugars and starches and ultimately atmospheric carbon are considered to not further contribute to the greenhouse effect. [0011] In addition to adding carbon dioxide to the atmosphere, current methods of industrial production of glycols produce contaminants and waste products that include among them sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, oxalic acid tartaric acid, acetic acids, Alkali metals, alkaline earth metals, transitional metals and heavy metals, including Iron, cobalt, nickel, copper, silver, molybdenum, tungsten, vanadium, chromium, rhodium, palladium, osmium, iridium, rubidium, and platinum (U.S. Pat. Nos. 2,434,110, 5,034,134, 5,334,778, and 5,10,036). [0012] Also of concern to consumers, especially consumers of deodorant and antiperspirant products, is an individual's reaction to such a product. The rate of development of hypersensitivity has markedly increased in the US in the last two decades. Many of these reactions are attributed to trace amount of substances. Other reactions are of idiopathic origin. Consumers seek products that are composed of ingredients of a more purified source and/or of all natural composition. SUMMARY OF THE INVENTION [0013] The present invention is directed to a deodorant or antiperspirant composition comprising 1,3-propanediol and a substantially natural ingredient, wherein said 1,3-propanediol has a bio-based carbon content of at least 1%. [0014] The present invention is further directed to a deodorant or antiperspirant composition comprising 1,3-propanediol and, a substantially natural ingredient wherein the substantially natural ingredient comprises at least 70% ingredients of natural origin. [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. [0017] The present invention is even further directed to a deodorant or antiperspirant composition comprising 1,3-propanediol, wherein the 1,3-propanediol in said composition has an anthropogenic CO.sub.2 emission profile of zero upon biodegradation.
