Definitions
- 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 well-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.
- US-A-4 179 382 describes a combination of a conventional cationic fabric softener active ingredient such as tetraalkylammonium salts or alkylimidazolinium salts with a small amount of a polymeric special cationic salt such as cationic starch or cationic polyvinylpyrrolidone copolymers.
- Textile laundry detergents with a stiffening effect are described in EP-A-0 017 120. They contain non-ionic and / or zwitterionic surfactants, water-soluble quaternary ammonium groups containing amino ethers of polysaccharides as well as framework salts and / or solvents which bind calcium ions.
- a skin-mild shampoo contains a combination of the nonionic surfactant alkyl polyglycoside and a cationic polymer.
- the mixture leads to excellent creamy foam.
- a liquid detergent containing discoloration-inhibiting additives is described in EP-A-0 044 003.
- the detergent contains two different nonionic surfactants, one of which is an ethoxylated C 13 -C 15 oxo alcohol with 55-65% by weight ethylene oxide and the other an ethoxylated C 9 -C 12 oxo or fatty alcohol with 60-70% by weight.
- % Is ethylene oxide, laundry softening quaternary ammonium compounds such as distearyldimethylammonium chloride or quaternary imidazolinium compounds and cationic starch ethers as discoloration inhibitors.
- the object of the invention was to produce a new fabric softener that is free of traditional quaternary ammonium bases with their known disadvantages.
- the solution to the problem is emulsions of nonionic hydrophobic To add surfactants with a cationic protective colloid. That way the surfactant vesicles present in the emulsion are superficially cationized, so that the Tucked onto the textile fiber to be rinsed substantively.
- nonionic fabric softening agents in particular as a hydrophobic component two similarly long C chains - the chain length of which can be C 10 - C 22 - and as a hydrophilic component a nonionic polyether or polyol chain or one Sugar or polysacchrid derivative included.
- 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 present as a mixture of mono-, di- and triesters.
- the degree of hydrophilization can be varied 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-A-38 26 179).
- cationic protective colloid in fabric softener formulations is not yet known Generally colloidal Solutions can be stabilized considerably by means of hydrophilic protective colloids.
- the Protective colloid forms a film around the particle to be protected and forms one Shell of water molecules from known protective colloids are gelatin, protein hydrolyzate, Glue etc.
- a suitable cationic protective colloid is the technically accessible cationic starch (I). You can find it in the Paper industry use. Compared to the electroneutral protective colloids the advantage that they are substantive to the negatively charged cellulose fiber of the paper is raising.
- Suitable cationic protective colloids in fabric softener formulations are the natural product chitosan (II) and chitosan derivatives.
- 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 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. 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 rinsing liquor.
- 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 in Form of a sensory soft grip test with 6 test persons as follows carried out:
- test subjects were each given 3 wipes in encrypted form after the Test plan according to table A (so-called triangular test) submitted.
- the task for the The examiner consisted of the differently treated cloth after sensory assessment find out.
- the examiner noted whether the different cloth was softer or feels harder. If at least 5 or 6 examiners found the cloth treated differently (T according to DIN 10 951 with examiners 1 to 3, S with examiners 4 to 6) a probability of greater than 95% between the test substance and the Standard a significant difference. The result is calculated using 3 numbers Expressed: The 1st number indicates the number of examiners who with the standard treated wipes felt softer or those with the test substance harder.
- the 2nd number indicates the number of examiners who treated the wipes treated with the standard perceived as harder or that with the test substance as softer
- the 3rd number gives finally the number of examiners due to the low sensory Differences in the wipes treated with the test substance or the standard cloth treated differently could not determine or the correct answer gave.
- 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 C 18 diglyceride (21% triglyceride) ethoxylated with 22% by weight EO was used.
- a Guerbet alcohol ethoxylated 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 by adding 1 to 5% by weight of a common one Emulsify fatty acid ethoxylate as an emulsifier in the presence of the protective colloids.
- Solubilizer served acetic acid or lactic acid, used in such amounts was that a pH of 4.5 to 5.0 was ensured in the diluted rinse liquor.
- chitosan 20% strength, stable, flowable emulsions could be produced will.
- the cationic starch and the polyamine alkyllacrylamide those were Emulsions 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).
- 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.

Description
Appretierend wirkende Textilwaschmittel mit steifender Wirkung werden in EP-A-0 017 120 beschrieben. Sie enthalten nichtionische und/oder zwitterionische Tenside, in Wasser lösliche quartäre Ammoniumgruppen aufweisende Aminoether von Polysacchariden sowie Calciumionen bindende Gerüstsalze und/oder Lösemittel.
Ein hautmildes Shampoo enthält nach EP-A-0 337 354 eine Kombination aus dem nichtionischen Tensid Alkylpolyglycosid und einem kationischen Polymer. Die Mischung führt zu ausgezeichnetem cremigen Schaum.
Ein flüssiges Waschmittel mit einem Gehalt an verfarbungsinhibierenden Zusätzen wird in EP-A-0 044 003 beschrieben. Das Waschmittel enthält zwei verschiedene nichtionische Tenside, von denen eines ein ethoxylierter C13-C15-Oxoalkohol mit 55 - 65 Gew.-% Ethylenoxid und das andere ein ethoxylierter C9-C12-Oxo- oder Fettalkohol mit 60 - 70 Gew.% Ethylenoxid ist, wäscheweichmachende quartäre Ammoniumverbindungen wie Distearyldimethylammoniumchlorid oder quartäre Imidazoliniumverbindungen und kationische Stärkeether als Verfarbungsinhibitoren.
wobei die Emulsionen oder Dispersionen
Eine ökologisch interessante Stoffklasse stellen die Saccharid-Difettsäureester oder die Fettalkylpolyglycosid-Fettsäureester dar, die auch im Gemisch vorliegen können. Bei Bedarf kann auch hier der Hydrophilierungsgrad zusätzlich mit Ethylenoxid oder Propylenoxid erhöht werden.
Eine andere bekannte Stoffklasse stellen die Fettsäureester des Sorbitols oder des Sorbitans dar, die bevorzugt als Gemisch von Mono- Di- und Triester vorliegen. Auch hier kann der Hydrophilierungsgrad durch Alkylenoxid-Addition vaniert werden. Die Diglyceride zählen zu der ökologisch und wirtschaftlich interessantesten Stoffklasse, da sie sich auf Basis billiger natürlicher Fette und Öle herstellen lassen und biologisch gut abbaubar sind. Auch hier wird der geeignete Hydrophilierungsgrad durch Alkoxylierung eingestellt. Ihre Herstellung ist Stand der Technik (DE-A-38 26 179).
Chitosan hat ein Molgewicht von 300 bis 500 000 und hat im Vergleich zur kationischen Stärke eine höhere positive Ladungsdichte. Als primäres Polyamin ist es als kationisches Schutzkolloid nur in sauren Systemen wirksam.
Neben den natürlichen kationischen Polymeren sind auch synthetische Polymere als erfindungsgemäßer Schutzkolloid-Zusatz geeignet, wie beispielsweise Polymere oder Copolymere des Dimethylaminopropyl-acrylamids oder -methacrylamids, die technisch zugänglich sind (III).
Die bevorzugte Menge beträgt 1 bis 20 %. Die Schutzkolloide können dem Wasser auch vor dem Emulgierungsprozeß zugesetzt werden Im Falle des Chitosans ist die Zugabe von organischer Säure als Lösungsvermittler erforderlich, um einen pH von 4 bis 5 in der Spülflotte zu gewährleisten.
Durchgeführte Weichspülteste haben gezeigt, daß nichtionische Tenside mit mindestens zwei langen hydrophoben Ketten in Kombination mit kleinen Mengen an kationischem Schutzkolloid gute Wäscheweichspüleffekte zeigen. Aus ökologischer Sicht sind insbesondere alkoxylierte Diglyceride auf Basis natürlicher Fette in Kombination mit dem Naturprodukt Chitosan geeignet. Das System ist biologisch gut abbaubar und enthält keine quaternären Aminfunktionen.
