Definitions
- the present invention relates to low-concentration, highly viscous aqueous Fabric softener in the form of aqueous emulsions or dispersions.
- Cationic compounds are usually used as fabric softener, for example quaternary ammonium compounds, which in addition to long-chain Alkyl radicals can also contain ester or amide groups, for example as in U.S. Patent 3,349,033, 3,644,203, 3,946,115, 3,997,453, 4,073,735, 4,119,545, etc. These components are used alone or in Mixtures with other cationic or neutral substances in Form of aqueous dispersions added to the rinsing bath.
- Ammonium compounds containing ester bonds are frequently used as for example in EP-A-0 239 910, US-PS 3 915 867, US-PS 4 137 180, U.S. Patent 4,830,771.
- Ester compounds based on triethanolamine such as N-methyl, N, N-bis (beta-C 14-18 -acyloxyethyl), N-beta-hydroxyethyl ammonium methosulfate, are particularly widespread and are available under trade names such as TETRANYL® AT 75 (trademark of KAO Corp.), STEPANTEX® VRH 90 (trademark of Stepan Corp.) or REWOQUAT® WE 18 (trademark of Witco Surfactants GmbH).
- esterquats have the previous raw materials distearyldimethylammonium chloride (DSDMAC) and imidazolinium quats within Europe replaced almost everywhere. The consumer requirements for these funds fluctuate however, significant within this market.
- DMDMAC distearyldimethylammonium chloride
- imidazolinium quats within Europe replaced almost everywhere. The consumer requirements for these funds fluctuate however, significant within this market.
- the desired or required viscosities of these products to achieve the desired effect is in the range of about 500 mPa * s or preferably above.
- This size was traditional with the laundry soft raw materials used (e.g. DSDMAC) easily accessible, without the need for additional viscosity regulators. With the esterquats it is due to the different viscosity behavior of these raw materials become difficult to achieve the desired high viscosities without additional to achieve high-priced thickeners.
- the object of the invention was to overcome the above-mentioned disadvantages of conventional overcome low concentration fabric softener formulations and fabric softener to provide that in addition to good biodegradability much improved level of good soft grip while maintaining have good rewetting power and without the addition of thickeners Achieve viscosities of> 500 mPa * s.
- the object is achieved by using quaternary fatty acid amino alcohol esters from triethanolamine with partially hydrogenated fatty acids in the ratio of 1: 1.6 to 1: 2 in alcohols or glycols.
- Another object of the invention is a method for producing low-concentration, high-viscosity fabric softener formulations, which thereby is characterized in that the compounds of general formula (I) in Temperatures between 28 ° C and 45 ° C preheated water, if necessary with the use of solvents, dyes and perfume oils, be entered and dispersed.
- the fat components for the esterification or transesterification are the known and usual monobasic fatty acids based on natural vegetable and animal oils with in particular 14-18 carbon atoms, used, such as tallow fatty acids and palm fatty acids or their methyl or Ethyl ester.
- the iodine number as a measure of the average degree of saturation of a Fatty acid, is the amount of iodine, which is from 100 g of the compound for saturation of the double bonds.
- Partially hydrogenated tallow fatty acids and palm fatty acids are preferred according to the invention with iodine numbers between 15-25. They are commercial products and are offered by various companies under their respective trade names.
- the esterification or transesterification is carried out according to known methods.
- the triethanolamine with the desired degree of esterification appropriate amount of fatty acid or fatty acid ester if appropriate in the presence of a catalyst, e.g. B. methanesulfonic acid, under nitrogen 160-240 ° C implemented and the water of reaction or alcohol formed distilled off continuously, optionally to complete the reaction the pressure can be reduced.
- a catalyst e.g. B. methanesulfonic acid
- the subsequent quaternization is also carried out using known processes.
- the procedure according to the invention is preferably such that the ester, if appropriate using a solvent, preferably with in particular Isopropanol, ethanol, 1,2-propylene glycol and / or dipropylene glycol, at 60-90 ° C with equimolar amounts of the quaternizing agent with stirring, optionally under pressure, and the completion of the reaction is monitored by checking the total number of amines.
- Examples of the quaternizing agents used are short-chain dialkyl phosphates and sulfates such as diethyl sulfate, dimethyl phosphate, diethyl phosphate, short chain halogenated hydrocarbons; in particular according to the invention Dimethyl sulfate used.
- Triethanolamine was used to produce the quaternary ammonium compounds (TEA) and fatty acids implemented according to the usual procedures and quaternized.
- the fatty acids were also used
- the fabric softener is produced by emulsifying or dispersing of the individual components in water. This can be done on this Conventional procedures are applied.
- the fabric softener according to the invention can the specified components within the in this area Desired limits, such as 3 to 10 wt .-%, preferably 4 to 5% by weight of the compounds of the general formula (I); 0.2-2 % By weight of a solvent such as in particular isopropanol, ethanol, propylene glycol, Dipropylene glycol; 0.1-1.0% by weight of perfume oil and the rest of 100 % By weight (ad 100) water.
- a solvent such as in particular isopropanol, ethanol, propylene glycol, Dipropylene glycol
- perfume oil 0.1-1.0% by weight of perfume oil and the rest of 100 % By weight (ad 100) water.
- the application concentration after dilution with water lies in the range depending on the application 0.1-1.0 g of at least one of the compounds of the general formula (I) per rinse cycle.
