For example, silicones can to impart a light and smooth feeling on the skin in cosmetic formulations, and can be used in hair products to provide conditioning, shine, or strengthening. However, silicones can have ecological disadvantages. Research has been directed to preparing substitutes for silicone without losing the desired benefits.

[0018] The nonaqueous, silicone-free personal care composition can be substantially free of silicone and substantially free of water. As used herein, "substantially free of silicone" means the composition has less than 5 weight percent (wt%), or less than 4 wt%, or less than 3 wt%, or less than 2 wt%, or less than 1 wt% of a silicone material, based on the total weight of the composition. As used herein, "substantially free of water" means the composition has less than 5 wt%, or less than 4 wt%, or less than 3 wt%, or less than 2 wt%, or less than 1 wt% of water. [0019] The nonaqueous, silicone-free personal care composition can further include an effective amount of a propellant. For example, the propellant can be a hydrocarbon propellant that includes one or more hydrocarbons or halogenated derivatives thereof, such as a C_l-7 alkane, Ci haloalkane, C_2-4 ether, C_2-4 haloether, or the like.

In other aspects, the propellant can be an aerosol propellant such as a compressed gas, soluble gas, liquefied gas, or a combination thereof. Exemplary aerosol propellants include, but are not limited to, nitrous oxide, carbon dioxide, nitrogen, helium, ambient air, or the like. The propellant can be included in the composition in any effective amount, for example 0.1 to 10 wt%, preferably 0.5 to 8 wt%, more preferably 1 to 5 wt%, based on the total weight of the composition.

[0020] The personal care composition can have a melting point of from 20 to 90°C, or 30 to 90°C, preferably 30 to 80°C, or 40 to 80°C, more preferably 40 to 70°C, or 50 to 70°C, as determined according to ASTM D87.

[0021] The personal care composition can have a congealing point of from 40 to l00°C, or 45 to l00°C, or 50 to l00°C, preferably 50 to 90°C, or 55 to 85°C, more preferably 60 to 80°C, as determined according to ASTM D938.

[0022] The personal care composition can have a needle pen penetration at 25 °C of from 0.2 to 4 mm, preferably 0.2 to 3 mm, more preferably 0.2 to 2.5 mm, or 0.4 to 2.5 mm, or 0.8 to 2.5 mm, or 1 to 2.5 mm, as determined according to ASTM D1321.

[0025] The dialkyl carbonates such as the bis(Ci_₃₆ alkyl)carbonate can be prepared via urea alcoholysis, for example by reacting urea and an alcohol. As illustrated in Scheme 1, carbamate (III) can be produced in- situ via a first reaction of urea (I) and a first equivalent of alcohol ROH (II), and the carbamate (III) reacts with a second equivalent of alcohol ROH (II) to yield a dialkyl carbonate (V). In both steps, ammonia (IV) is produced. Alternatively, the reaction can be performed sequentially, for example by using a lower temperature to form the carbamate (III) and a higher temperature to form the dialkyl carbonate (V). The ammonia (IV) that is produced from each reaction step can be separated and reacted with carbon monoxide to regenerate urea (I), thus providing a method to recycle the urea starting material. In Scheme 1, R is a Ci-36 alkyl.

111 II V ^IV Scheme 1

[0026] Preparing the bis(Ci_₃₆ alkyl)carbonate using this method can provide a convenient route to manufacture dialkyl carbonates from aliphatic alcohols. Moreover, the dialkyl carbonates can be obtained without the need for phosgene or requiring a multi-step process such as oxidative carbonylation followed by transesterification. Because urea can be synthesized from ammonia and carbon dioxide, combining the reactions of urea synthesis and urea alcoholysis can provide for the preparation of bis(Ci_₃₆ alkyl)carbonate with a net input of only the aliphatic alcohol. In an aspect, the method for the manufacture of the personal care composition does not include the use of phosgene.

[0027] The ammonia gas formed as byproduct in the reaction of urea and the alcohol can be preferably removed from the reaction system. The process for the removal of byproduct ammonia gas is not particularly limited and the removal can be effected by attaching a fractionation column to the reactor to separate ammonia from other high-boiling components, or adding a deammoniation agent that can react with ammonia to remove it, for example hydrogenated molecular sieves.

[0028] The reaction of the alcohol and urea can be done in the presence of a catalyst. Exemplary catalysts can include Ti, Al, Zn, Pb, Sn, Ca, Mg, Zr, Rb, Cs, Na, K, ammonium, or a combination thereof. For example, the catalyst can be a titanium tetra(Ci_₆ alkoxide), an aluminum tri(Ci_₆ alkoxide), a zirconium tetra(Ci_₆ alkoxide), a di(Ci-₆ alkyl)tin oxide, a di(Ci-₆ alkyl)tin di(Ci_₃alkoxide), a tri(C_{6 i}2 aryl)tin halide, or a combination thereof. Other examples of catalysts include, but are not limited to, sodium hydroxide, potassium hydroxide, magnesium hydroxide, rubidium hydroxide, cesium hydroxide, sodium carbonate, potassium carbonate, rubidium carbonate, cesium carbonate, zinc oxide, zinc nitrate, zinc chloride, zinc acetate, zinc hydroxide, zinc carbonate, lead oxide, lead acetate, lead nitrate, calcium oxide, magnesium oxide, zirconium oxide, tetramethylammonium hydroxide, tetraethylammonium hydroxide, ditetramethylammonium carbonate, ditetraethvlammonium carbonate, or a combination thereof. [0029] The amount of catalyst can be from 0.005 to 10 mole percent (mol%), preferably 0.1 to 5 mol%, more preferably 0.5 to 3 mol%, based on the number of moles of urea.

[0032] The reaction of the alcohol and urea can be performed at 130 to 250°C, or 150 to 220°C, or 170 to 200°C. The reaction temperature can be for 0.5 to 20 hours, or 2 to 15 hours, or 5 to 12 hours.
