Definitions

• DMDMAC distearyldimethylammonium chloride
• plasticizer emulsions are applied here in a relatively high concentration (10-50 g / l) according to various methods such as spraying, application or exhausting, depending on which soft effect is desired.
• a good household laundry softener is required to draw on the textiles to be treated as quantitatively as possible from a highly diluted washing liquor emulsion (0.2 to 0.7 g / l).
• the known good effect of the classic cationic fabric softener is based above all on the pronounced chemisorptivity of the emulsified cationic particles, which are absorbed by the ionic interaction with the anionic fiber surface on the fiber. It is known from the literature that good fabric softening effects can be achieved by mixing nonionic and cationic plasticizers. So z. B.
• the object of the invention was to produce a new fabric softener that is free of the traditional quaternary ammonium bases with their known disadvantages.
• the solution to the problem is to add a cationic protective colloid to emulsions of nonionic hydrophobic surfactants.
• the surfactant vesicles present in the emulsion are cationized superficially, so that they are drawn up substantively onto the textile fiber to be rinsed.
• the invention therefore relates to an aqueous fabric softener for the treatment of textiles based on water-insoluble nonionic surfactants, the emulsions or dispersions of which are stabilized by the addition of protective colloids which contain cationic groups.
• nonionic fabric softening agents in particular as a hydrophobic component two similarly long C chains - the chain length of which can be C10 - C22 - and as a hydrophilic component a nonionic polyether or polyol chain or a sugar chain or polysacchrid derivative.
• Guerbet alcohols which are produced by alkaline condensation of fatty alcohols.
• the suitable degree of hydrophilization can be set by adding ethylene oxide or propylene oxide.
• An ecologically interesting class of substances are saccharide difatty acid esters or fatty alkyl polyglycoside fatty acid esters, which can also be present in a mixture. If necessary, the degree of hydrophilization can also be increased with ethylene oxide or propylene oxide.
• Another known class of substances are the fatty acid esters of sorbitol or sorbitan, which are preferably a mixture of mono-, di- and triesters available.
• the degree of hydrophilization can also be varied here by addition of alkylene oxide.
• the diglycerides belong to the most ecologically and economically interesting class of substances because they can be produced on the basis of cheap natural fats and oils and are easily biodegradable.
• the appropriate degree of hydrophilization is set by alkoxylation.
• Their manufacture is state of the art (DE 38 26 179).
• cationic protective colloid in fabric softener formulations is not yet known.
• colloidal solutions can be considerably stabilized using hydrophilic protective colloids.
• the protective colloid wraps itself around the particle to be protected like a film and forms a shell of water molecules.
• Known protective colloids are gelatin, protein hydrolyzate, glue and others.
• a suitable example of a cationic protective colloid is the technically accessible cationic starch (I). It is used, among other things, in the paper industry. It has the advantage over the electroneutral protective colloids that it draws substantially onto the negatively charged cellulose fiber of the paper.
• Chitosan has gained economic importance as a renewable raw material mainly in Japan and the USA in recent years. It is produced by deacetylation of chitin, a waste product from crab fishing. Chitin is the second most common polysaccharide on earth after cellulose. Chitosan has a molecular weight of 300 to 500,000 and has a higher positive charge density than the cationic starch. As a primary polyamine, it is only effective as a cationic protective colloid in acidic systems.
• synthetic polymers are also suitable as protective colloid additives according to the invention, such as, for example, polymers or copolymers of dimethylaminopropyl acrylamide or methacrylamide, which are technically accessible (III).
• the nonionic water-insoluble surfactants exemplified are prepared in concentrations of 5 to 20% with the aid of small amounts of conventional emulsifiers such as fatty alcohol ethoxylates and, if appropriate, with the addition of acetic acid or lactic acid as solubilizer, aqueous emulsions.
• the cationic protective colloids mentioned as examples are added to this emulsion in amounts of 0.1 to 50%, based on the nonionic active substance. The preferred amount is 1 to 20%.
• the protective colloids can also be added to the water before the emulsification process.
• chitosan In the case of chitosan, the addition of organic acid as a solubilizer is necessary to ensure a pH of 4 to 5 in the rinse liquor.
• a primary polyamine As a primary polyamine, chitosan is only effective as a cationic protective colloid in an acid medium.
• the fabric softener emulsions thus produced are diluted so heavily during laundry treatment that the active substance combination is present in the rinse liquor in a concentration of 0.1 to 1 g / l.
• Fabric softener tests carried out have shown that nonionic surfactants with at least two long hydrophobic chains in combination with small amounts of cationic protective colloid show good fabric softening effects.
• alkoxylated diglycerides based on natural fats in combination with the natural product chitosan are particularly suitable.
• the system is readily biodegradable and contains no quaternary amine functions.
• the softening effect of the fabric softener claimed was carried out in the form of a sensory soft handle test with 6 test persons as follows: A batch of 72 terry towels (44 cm x 30 cm, approx. 60 g, from WFK-Testgewebe GmbH), even if not all 72 towels were used (for reasons of even wear), once with 100 g of a commercially available heavy-duty detergent (PERSIL) machine washed at 95 ° C, rinsed and spun. This is followed by a washing process at 95 ° C. without detergent, including rinsing and a brief spin-on, so that clean, moist cloths containing approximately 2.5 times their dry weight of water could be removed for manual fabric softening.
• PERSIL heavy-duty detergent
• test subjects were each presented with 3 wipes in encrypted form according to the test plan according to Table A (so-called triangular test).
• the task for the examiner was to find out the differently treated cloth after sensory assessment.
• the result is expressed with the help of 3 numbers: The 1st number indicates the number of examiners who found the wipes treated with the standard to be softer or those with the test substance as harder. The second number indicates the number of examiners who found the wipes treated with the standard to be harder or those with the test substance as softer. The third number finally indicates the number of examiners who, due to the small sensory differences between the wipes treated with the test substance and the standard, could not determine the wipe treated differently or did not give the correct answer.
• the ecologically and economically interesting diglycerides based on natural fats were the preferred test substances.
• a palm oil propoxylated with 15% by weight of propylene oxide and a skin fat from Stockhausen propoxylated with 15% by weight of propylene oxide were tested.
• a synthetic, with 22 wt .-% EO ethoxylated C18 diglyceride (21% triglyceride) was used.
• a Guerbet alcohol oxidized with 12 EO was used, which was synthesized by alkaline condensation of a technical C 16/18 fatty alcohol.
• a technical product with a degree of cationization of 0.02 to 0.03 from Cerestar was selected as the cationic starch.
• the chitosan was used as a cold-soluble hydrochloride (Kyowa Oil and Fat, Japan).
• a technical polyaminoacrylamide copolymer with an acrylic acid content of 10% by weight and a molecular weight of approx. 1 million from the company Stockhausen was used as the synthetic protective colloid.
• the active ingredients could easily be added 1 to 5% by weight of a common fatty acid oxyethylate as an emulsifier in the presence of the protective colloids emulsify.
• Acetic acid or lactic acid was used as the solubilizer, which was used in such quantities that a pH of 4.5 to 5.0 was ensured in the diluted rinsing liquor.
• chitosan 20% good flowable, stable emulsions could be produced.
• the cationic starch and the polyamine alkyl acrylamide the emulsions were 10%.
• Table 1 shows the test results compared to an untreated cloth. In all cases the addition of cation causes.
• Protective colloid has a significant soft feel. In comparison to a commercially available ester quat, the same softness is achieved if the rinse liquor concentration is doubled (see Table 2).
• Table 1 Sensory soft grip test with 6 test persons according to DIN 10951 (so-called triangle test) Comparison against untreated cloths washed with PERSIL Washing liquor Triangle test Test substance 0.35 g / l cation.
