Description

Fabric softener active composition and method for making it
The present invention relates to fabric softener active compositions comprising tris- (2-hydroxyethyl) - methylammonium methylsulfate fatty acid esters and having a low content of methanol and to a method for making such compositions .
Quaternary ammonium salts carrying two hydrophobic long chain hydrocarbon moieties have found broad use as fabric softener actives. Quaternary ammonium salts of
alkanolamines esterified with on average two fatty acid moieties per molecule, commonly referred to as ester quats, have largely replaced earlier alkyl quaternary ammonium compounds because of their biodegradability .
Tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid esters made by quaternizing fatty acid esters of triethanolamine with dimethylsulfate have found broad use as fabric softener actives. Since dimethylsulfate is a potential carcinogen, quaternization is carried out to achieve complete conversion of dimethylsulfate and a high conversion of amine. It has now been found that tris-
(2-hydroxyethyl) -methylammonium methylsulfate fatty acid esters made this way contain unexpectedly high amounts of methanol. Although tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid ester softener actives have been in use for more than 20 years, the high content of methanol in these compositions has up to now remained unnoticed.
Since methanol is toxic and presents a workplace hazard, there is therefore a need to provide fabric softener active compositions comprising tris- (2-hydroxyethyl) - methylammonium methylsulfate fatty acid esters which compositions have a low content of methanol. There is also a need for a simple method for making such compositions. It has now been found that fabric softener active
compositions comprising tris- (2-hydroxyethyl) - methylammonium methylsulfate fatty acid esters and having a low content of methanol can be made by reacting fatty acid esters of triethanolamine with dimethylsulfate at reaction conditions where a higher total amine value than in prior art methods is achieved at complete dimethylsulfate
conversion .
The present invention is therefore directed to a fabric softener active composition, comprising a) from 65 to 98 % by weight of at least one tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid ester, b) at least one tris- (2-hydroxyethyl) -amine fatty acid ester in an amount providing a total amine number of the composition of from 7 to 20 mg KOH/g, and c) from 1 to 1500 ppm methanol.
The invention is further directed to a method for making a fabric softener active composition comprising from 65 to 98 % by weight of tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid esters and from 1 to 1500 ppm methanol, wherein at least one tris- (2-hydroxyethyl) -amine fatty acid ester is reacted with dimethylsulfate at a molar ratio of dimethylsulfate to amine nitrogen of from 0.79 to 0.94 until the reaction mixture has a total amine number of from 7 to 20 mg KOH/g.
The fabric softener active composition of the invention comprises from 65 to 98 % by weight of at least one tris-
(2-hydroxyethyl) -methylammonium methylsulfate fatty acid ester. The composition further comprises at least one tris-
(2-hydroxyethyl) -amine fatty acid ester in an amount providing a total amine number of the composition of from 7 to 20 mg KOH/g, preferably from 8 to 13 mg KOH/g and more preferably from 9 to 12 mg KOH/g. The total amine number is determined by non-aqueous titration with perchloric acid according to method Tf 2a-64 of the American Oil Chemists Society and is calculated as mg KOH per g sample. The fatty acid moiety of the tris- (2-hydroxyethyl) - methylammonium methylsulfate fatty acid ester can be derived from a pure fatty acid or a mixture of fatty acids of formula RCOOH, where R is a hydrocarbon group. The hydrocarbon group may be branched or unbranched and
preferably is unbranched. The fatty acid moiety of the tris- (2-hydroxyethyl) -amine fatty acid ester may be derived from the same or a different fatty acid or mixture of fatty acids. Preferably, the tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid esters and the tris- (2-hydroxyethyl) -amine fatty acid esters have the same fatty acid moieties.
The tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid ester may comprise monoesters of formula
CH3N+ (CH2CH2OH) 2 ( CH2CH2OC (=0) R) CH3OS O4" , diesters of formula CH3N+ ( CH2CH2OH ) ( CH2CH2OC (=0) R) 2 CH3OS O4" , and triesters of formula CH3N+ (CH2CH2OC (=0) R) 3 CH3OS O4" , where R is the hydrocarbon group of a fatty acid moiety RCOO. The tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid ester preferably has an average molar ratio of fatty acid moieties to nitrogen of from 1.4 to 2.0 and more preferably of from 1.5 to 1.8. The specified molar ratio provides high softening performance in a rinse cycle fabric softener.
The fatty acids corresponding to the fatty acid moieties of said tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid esters preferably have an iodine value of from 0.5 to 120, more preferably from 1 to 50 and most
preferably from 30 to 45. The iodine value is the amount of iodine in g consumed by the reaction of the double bonds of 100 g of fatty acid, determined by the method of ISO 3961. The fatty acid moieties of the tris- (2-hydroxyethyl) - methylammonium methylsulfate fatty acid esters preferably have an average chain length of from 16 to 18, more
preferably of from 16.5 to 17.8 carbon atoms. The average chain length is calculated on the basis of the weight fraction of individual fatty acids in the mixture of fatty acids . For branched chain fatty acids the chain length refers to the longest consecutive chain of carbon atoms.
The preferred iodine values and average chain lengths provide a suitable combination of good processability of the fabric softener composition in terms of melting point and viscosity and high fabric softening efficiency in a rinse cycle fabric softener.
In order to provide the required average chain length and iodine value, the fatty acid moiety can be derived from a mixture of fatty acids comprising both saturated and unsaturated fatty acids. The unsaturated fatty acids are preferably monounsaturated fatty acids. The tris- (2-hydroxyethyl) -methylammonium methylsulfate fatty acid ester preferably comprises less than 10 % by weight of multiply unsaturated fatty acid moieties and more
preferably less than 6 % by weight. Examples of suitable saturated fatty acids are palmitic acid and stearic acid. Examples of suitable monounsaturated fatty acids are oleic acid and elaidic acid. The cis-trans-ratio of double bonds of unsaturated fatty acid moieties is preferably higher than 55:45 and more preferably higher than 65:35. The fraction of multiply unsaturated fatty acid moieties may be reduced by selective touch hydrogenation, which is a hydrogenation that selectively hydrogenates one double bond in a -CH=CH-CH2-CH=CH- substructure but not double bonds of monounsaturated hydrocarbon groups.
The fabric softener active composition of the invention also comprises from 1 to 1500 ppm methanol and preferably from 10 to 800 ppm methanol, based on the weight of the composition. This methanol content is lower than in prior art fabric softener compositions containing a similar amount of tris- (2-hydroxyethyl) -methylammonium
methylsulfate fatty acid esters made by reacting a tris- (2-hydroxyethyl) -amine fatty acid ester with
dimethylsulfate . The methanol content of the composition can be determined by head space GLC analysis with
calibration by spiking with known amounts of methanol. The fabric softener composition is preferably diluted with a suitable solvent, such as dimethylformamide, to reduce the viscosity for accurate head space GLC analysis. The lower content of methanol in the fabric softener active
composition of the invention reduces the need for work safety precautions and the requirements for product
labelling and classification and increases the flash point of the composition compared to prior art compositions.
The fabric softener active composition of the invention may further comprise one or more additional organic solvents. The composition preferably comprises up to 35 % by weight of a solvent selected from ethanol, 1-propanol, 2-propanol, ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, Ci-C4-alkyl monoethers of ethylene glycol and Ci-C4-alkyl monoethers of propylene glycol. The amount of additional solvent is most preferably from 5 to 20 % by weight. The more preferred solvents are ethanol,
1-propanol and 2-propanol, most preferably ethanol or
2-propanol and in particular 2-propanol.
The fabric softener active composition of the invention can be prepared by the method of the invention, where at least one tris- (2-hydroxyethyl) -amine fatty acid ester is reacted with dimethylsulfate at a molar ratio of dimethylsulfate to amine nitrogen of from 0.79 to 0.94 until the reaction mixture has a total amine number of from 7 to 20 mg KOH/g. The total amine number can be determined by non-aqueous titration with perchloric acid according to method Tf 2a-64 of the American Oil Chemists Society and is calculated as mg KOH per g sample. The reaction can be terminated by lowering the temperature once the desired total amine number in this range has been reached. Preferably, the reaction is continued until substantially all of the dimethylsulfate has reacted.
Choosing a molar ratio of dimethylsulfate to amine nitrogen in the specified range and carrying out the reaction until a total amine number of from 7 to 20 mg KOH/g has been reached provides high conversion of dimethylsulfate and at the same time avoids the formation of methanol in amounts exceeding 1500 ppm.
The molar ratio of dimethylsulfate to amine nitrogen is preferably chosen in the range from 0.85 to 0.90. The tris- (2-hydroxyethyl) -amine fatty acid esters are preferably reacted with dimethylsulfate at a temperature of from 60 to 95 °C, more preferably from 70 to 90 °C. The reaction is preferably carried out until the reaction mixture has a total amine number of from 8 to 13 mg KOH/g, most
preferably of from 9 to 12 mg KOH/g. The tris-
(2-hydroxyethyl) -amine fatty acid ester may be reacted with dimethylsulfate at any pressure, such as ambient pressure or reduced pressure. The reaction of the tris- (2-hydroxyethyl) -amine fatty acid ester with
dimethylsulfate may be carried out in the presence of an additional solvent, but is preferably carried out without addition of a solvent.
The tris- (2-hydroxyethyl) -amine fatty acid esters used in the method of the invention preferably have an average molar ratio of fatty acid moieties to nitrogen of from 1.4 to 2.0 and more preferably of from 1.5 to 1.8. The fatty acid moieties of the tris- (2-hydroxyethyl) -amine fatty acid esters preferably have an iodine value of from 0.5 to 120 and more preferably of from 1 to 50. The fatty acid
moieties of the tris- (2-hydroxyethyl) -amine fatty acid esters preferably have an average chain length of from 16 to 18 and more preferably from 16.5 to 17.8 carbon atoms.
The tris- (2-hydroxyethyl) -amine fatty acid ester starting material is preferably prepared by esterifying
triethanolamine with a fatty acid or fatty acid mixture, removing the water formed during esterification at reduced pressure. The tris- (2-hydroxyethyl) -amine fatty acid esters made this way can be used without further purification. The desired iodine value, average chain length and molar ratio of fatty acid moieties to nitrogen may be easily adjusted by the choice of fatty acid or fatty acid mixture and the molar ratio of triethanolamine to fatty acid used in the esterification reaction. The esterification is preferably carried out at a temperature of from 160 - 210 °C at ambient pressure distilling off water until 60 to 80 % of the theoretical amount of water has been removed. Then the pressure is reduced stepwise to a final pressure in the range of 20 to 50 mbar and the reaction is continued until an acid value of 1 to 10 mg KOH/g, more preferably 2 to 5 mg KOH/g, has been reached.
The invention is illustrated by the following examples, which are however not intended to limit the scope of the invention in any way.

167.7 g (1.33 mol) dimethylsulfate was added in small portions with stirring to 818 g (1.387 mol) tris- (2-hydroxyethyl) -amine tallow fatty acid ester from example 1, cooling the reaction mixture to maintain the temperature in the range from 70 to 90 °C. After all dimethylsulfate had been added, the reaction mixture was stirred for 1 h at 80 to 90 °C. Then 109.5 g 2-propanol was added and the mixture was stirred until homogeneous. The resulting composition had a total amine number of 3.4 mg KOH/g and contained 4450 ppm methanol, based on the weight of the composition .
Example 4 :
Example 3 was repeated using 160.44 g (1.272 mol)
dimethylsulfate, 808.8 g (1.369 mol) tris- (2-hydroxyethyl) - amine tallow fatty acid ester from example 1 and 107.47 g 2-propanol. The resulting composition had a total amine number of 6.0 mg KOH/g and contained 3000 ppm methanol, based on the weight of the composition. Example 5:
Example 3 was repeated using 144.55 g (1.146 mol)
dimethylsulfate, 755.4 g (1.282 mol) tris- (2-hydroxyethyl) - amine tallow fatty acid ester from example 1 and 100.0 g 2-propanol. The resulting composition had a total amine number of 8.9 mg KOH/g and contained 1400 ppm methanol, based on the weight of the composition. Example 6:
Example 3 was repeated using 135.1 g (1.072 mol)
dimethylsulfate, 780.1 g (1.324 mol) tris- (2-hydroxyethyl) - amine tallow fatty acid ester from example 1 and 102.0 g 2-propanol. The resulting composition had a total amine number of 17.2 mg KOH/g and contained 155 ppm methanol, based on the weight of the composition.
Examples 3 and 4 (not according to the invention) and examples 5 and 6 (according to the invention) demonstrate how the methanol content of fabric softener composition can be controlled by chosing the right molar ratio of tris- (2-hydroxyethyl) -amine fatty acid ester to dimethylsulfate and carrying out quaternization to a total amine number of the reaction mixture of from 7 to 20 mg KOH/g.
Example 7 (comparative) :
The preparation of di (acyloxyethyl) (2-hydroxyethyl) methyl ammonium methylsulfate with acyl groups derived from partially hydrogenated canola fatty acid described in column 43 lines 37 to 53 of patent US 6,995,131 was
repeated. The resulting composition contained 5500 ppm methanol, based on the weight of the composition.
