Definitions

  • Textiles which come into contact with human skin are often treated with active ingredients which soften the textile and which give the textiles a pleasantly soft feel.
  • active ingredients which soften the textile and which give the textiles a pleasantly soft feel.
  • Numerous textile-softening active substances are known, of which quaternary ammonium compounds with two or three long residues are used very frequently and on a large scale because of their good activity.
  • Such quaternary ammonium compounds are more readily degradable than the conventional quaternary ammonium compounds with fatty alkyl residues. Nevertheless, some of these more readily degradable quaternary ammonium compounds do not meet all the requirements for an ideal compound, since the degradation occasionally takes place via intermediate stages which are not entirely ecologically harmless. They can be produced in different ways, but it is generally difficult to obtain light-colored products that are accepted by the consumer. Additional operations are therefore often required to separate dark-colored products from light-colored ones, which increases the manufacturing costs for light-colored products. In addition, reagents are required for the quaternization reaction, the handling of which often requires additional safety measures. other. There is therefore still a need for textile-softening active ingredients which are readily biodegradable and which are degraded without the formation of ecologically unobjectionable intermediates and which can be easily prepared from conveniently handled starting materials.
  • esters of alkanolamines can be used as fabric softening agents.
  • the esters are derived from fatty acids, which can be natural or synthetic and accordingly can be straight-chain or branched, saturated or unsaturated and contain 6 to 24 carbon atoms per fatty acid residue.
  • Esters preferred for the use according to the invention are derived from fatty acids which contain 8 to 24 carbon atoms and which are easily and inexpensively obtained from natural fats.
  • Vegetable and animal fats come into question as sources of natural fats, for example coconut oil, palm kernel oil, sunflower oil, turnip oil, beef tallow, fish oil, sperm oil and the narrower or further fatty acid cuts produced therefrom.
  • esters of alkanolamines which are derived from pure or technical fatty acids, for example from lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, elaidic acid, behenic acid, acids which are derived from Guerbet alcohols and substituted acids, for example hydroxycarboxylic acids, are also very suitable.
  • esters of alkanolamines are alkanolamines with 1, 2 or 3 alkanol residues.
  • Esters which are particularly suitable for the use according to the invention are derived from alkanolamines whose alkanol groups contain 2 to 4, in particular 2 or 3, carbon atoms. These are, for example, ethanolamine, propanolamine and butanolamine, of which the ethanolamines and the propanolamines are particularly preferred.
  • Alkanolamines with 3 carbon atoms are derived from n-propanolamine or i-propanolamine.
  • Typical alkanolamines whose esters are suitable for the use according to the invention are, for example, dimethylethanolamine, ethyldiethanolamine, triethanolamine, diethylethanolamine, ethyldiethanolamine, dimethyl-n-propanolamine, methyldi-n-propanolamine, dimethyl-i-propanolamine, methyl-ii -propanolamine and the higher n-propyl or i-propyl homologues of mentioned connections.
  • esters derived from alkanolamines, the alkyl or alkanol residues of which are different in the molecule in the event that the molecule contains several alkyl or alkanol groups examples of such compounds are methyl ethyl ethanol amine, methyl i-propyl ethanolamine, methyl ethyl i-propanolamine or methyl ethyl n-butanolamine.
  • esters of alkanolamines mentioned are known compounds which are used as precursors to the quaternary ammonium compounds described in the abovementioned references. They can be produced by esterification of the alkanolamines with fatty acids, fatty acid halides and fatty acid esters, for example fatty acid ethyl ester or also with trifatty acid glycerides, the so-called triglycerides.
  • Esters highly suitable for the use according to the invention are derived from alkanolamines which are in salt form.
  • the salts of the alkanolamine esters are obtained by simply neutralizing the alkanolamine esters with acids. Salts of the esterified alkanolamines which have been obtained by neutralization with short-chain organic or inorganic acids are preferably used.
  • Short-chain organic acids are taken to mean mono- or polybasic acids, for example formic acid, acetic acid, oxalic acid, succinic acid, malonic acid, fumaric acid, but also substituted acids, such as citric acid, tartaric acid, glycolic acid, lactic acid, tartronic acid or gluconic acid.
  • Inorganic acids suitable for salt formation are, for example, hydrochloric acid, sulfuric acid, phosphoric acid or phosphorous acid.
  • the esters are 100 mol% in salt form.
  • it is advantageous that the alkanolamine esters are only in salt form at 30 to 90 mol.
  • Alkanolamine esters exist as salts of lactic acid or phosphorous acid.
  • a preferred use of the alkanolamine esters according to the invention takes place in aqueous treatment compositions which contain 0.5 to 20% by weight of the compounds mentioned as fabric softening active ingredients.
  • the esters mentioned are present in dissolved or dispersed form in aqueous treatment agents. Such treatment agents are used to treat freshly washed textiles.
  • Another possible use for the alkanolamine esters mentioned is their addition to detergents or wash liquors.
  • the textiles to be washed accumulate the alkanolamine esters on their surface during the washing process, which leads to an improvement in handle after rinsing and drying the textiles.
  • the inventive alkanolamine ester is also used as a fabric softening agent in tumble auxiliaries in which the fabric softener is applied to a substrate that transfers the active ingredients to the textiles in an automatic tumble dryer during the drying process.
  • the aqueous treatment agents preferably have a pH in the range from 2 to 7.
  • the treatment agents contain more or less different additives.
  • Aqueous treatment agents contain, for example, preservatives, opacifiers, viscosity regulators, fragrances, dyes, emulsifiers or dispersants.
  • the alkanolamine esters can also be used in combination with other textile-softening active ingredients. In some cases it may be expedient to add surface-active substances, optical brighteners or solubilizers. Examples
  • the end product contained 2.12% titratable nitrogen.
  • reaction product from Example 2 100 g of the reaction product from Example 2 were neutralized with 9.2 g of acetic acid and the hot melt at 80 ° C. was stirred into 436.8 g of water at 85 ° C.
  • the finely divided dispersion obtained after cooling contained 20% by weight of active ingredient.
  • the final product contained 2.14% titratable nitrogen.
  • reaction product 100 g of the reaction product were neutralized with 17 g of lactic acid, 80% strength, and the melt at 80 ° C. was stirred into 554.4 g of water at 85 ° C.
  • the finely divided dispersion obtained after cooling contained 20% by weight of active ingredient.
  • the final product contained 1.7% titratable nitrogen. 67.6 g of the end product were made up with 10.2 g of lactic acid, 80% strength and 422.2 g of water as in Example 3 to form a viscous, finely divided dispersion with 15% by weight of active ingredient.
  • Example 4 Analogously to Example 1, 677 g (2 mol) of the behenic acid used in Example 4 were reacted with 118.9 g (1 mol) of methyldiethanolamine.
  • the final product contained 1.79% titratable nitrogen.
  • Example 3 67.2 g of the end product, 10.7 g of lactic acid, 80% strength and 421.1 g of water were made up as in Example 3 to form a viscous, finely divided dispersion with 15% by weight of active ingredient.
  • the end product contained 1.66% titratable nitrogen.
  • Example 3 67.6 g of the end product, 10.2 g of lactic acid, 80%, and 422.2 g of water were made up as in Example 3 to form a viscous, finely divided dispersion with 15% by weight of active ingredient.

Abstract

Des esters d'acides gras, obtenus à partir d'alcanolamines avec 1, 2 ou 3 groupes alcanol, sont utilisables comme adoucissant textile. Dans de nombreux cas, il est utile d'employer les esters d'alcanolamines sous la forme de leurs sels d'acides inorganiques ou organiques. Les esters sont facilement biodégradables et exceptionnellement efficaces.
