Description

Propylene glycol esters as textilpflegende ingredients

The present invention relates to laundry detergents, laundry aftertreatment or laundry care products, in particular liquid detergents containing propylene glycol esters and their use to minimize the tendency to wrinkle and to ease the Bügeins of textiles, especially textiles made of cellulosic material, as well as a practicable in the home process for ironing and / or wrinkle-reducing finish of textiles.

Textiles made of cellulose, such as cotton or cellulose regenerated fibers (for example Modal or Lyocel) have from the consumer's point of view positive properties in terms of wearing comfort. However, a major disadvantage of these textiles is the slight creasing during wear, after washing and drying. This tendency to wrinkle is due to the swelling of the cellulose fibers and their low elastic restoring forces ("bounce") after deformation.

Therefore, it has been customary for a long time to iron cotton or cellulosic textiles after washing and drying and thus to bring them into the desired shape. For the consumer, however, it would be advantageous to be able to minimize the formation of wrinkles in the context of textile care, which would facilitate the work of ironing or, ideally, would make ironing completely superfluous.

In the textile production one tries with the help of permanent textile equipment by a cross linking of the cellulose molecules among themselves to reduce their tendency to crease. The crosslinking of the cellulose molecules increases the elasticity of the material. The anti-crease equipment is carried out as part of the textile finishing on the raw material. However, crosslinkers used in the textile industry, such as formaldehyde-urea and formaldehyde-melamine combinations, because of their toxicity or the conditions under which they must be used, are not suitable for use in detergents or household use suitable. Although alternative formaldehyde-free crosslinking processes for cellulose using polycarboxylic acids are known, for example from US 2004/0043915 A1, they are unsuitable for home use or for a consumer product.

There is therefore still a need for methods and products that reduce the tendency of textiles to crease. Another problem when washing textiles is that the textiles lose their softness after washing several times. For this reason, it is customary to use fabric softener or to dry the laundry in a dryer. However, there are a number of consumers who do not (want) use fabric softener or dryer. It is therefore desirable to provide detergents which already bring about a pleasant softness of the laundry during the normal washing process.

It has now surprisingly been found that the creasing tendency of cellulose-containing textiles, in particular textiles made of cotton and polyester / cotton fabric can be reduced by the use of washing, laundry aftertreatment or laundry care products containing propylene glycol esters. Furthermore, it has been found that the softness of the laundry after the washing process can be advantageously influenced by such means.

The invention therefore in a first aspect, a washing, Wächsenachbehandlungs- or laundry care, especially a liquid detergent, based on the total weight of 0.01 to 30 wt .-%, preferably 0.01 to 4 wt .-% of at least one propylene glycol - Kolesters according to formula (I) contains:

wherein R1 is an alkyl of 5-35 carbon atoms or an alkenyl of 5-35 carbon atoms;

wherein R2 is an alkyl of 5-35 carbon atoms or an alkenyl of 5-35 carbon atoms, and wherein Xi and X2 are not both -OH.

Another object of the invention is the use of such an agent containing at least one propylene glycol ester according to the invention in a concentration of 0.01 to 30 wt .-%, preferably 0.01 to 4 wt .-%, based on the total weight of the composition, to minimize creasing and to facilitate the ironing of textiles.

Yet another aspect of the invention is the use of the laundry, laundry aftertreatment or laundry care product described herein, especially liquid laundry detergent, including based on the total weight of the agent, from 0.01 to 30% by weight, preferably from 0.01 to 4% by weight, of at least one propylene glycol ester according to the invention for increasing the softness of textiles.

Finally, the invention also relates to a household washing process comprising the process steps

a) providing a washing or cleaning solution comprising a washing, laundry aftertreatment or laundry care, especially liquid detergents, as described herein, and

b) contacting a textile or a hard surface with the washing or cleaning solution according to (a).

The compositions described herein comprise at least one propylene glycol ester.

The propylene glycol ester of the present invention may be propylene glycol laurate, e.g. the connection Migoto type BP from the company Riken. However, it is also possible to use any other monoester of propylene glycol and fatty acids (for example propylene glycol isostearate, propylene glycol oleate and propylene glycol myristate). In the literature, these monoesters are described as adjuvants in the field of hair care, in the skin care sector and in the personal care sector.

As a result of the measures of the invention, the creasing tendency of textiles made of cellulose-containing material is considerably reduced compared to the untreated original textiles.

The process can be carried out, for example, by bringing textiles of cellulose-containing material into contact with an aqueous preparation which contains 0.01 to 30% by weight, preferably 0.1 to 4% by weight, of at least one propylene glycol ester according to the invention. This can be done as part of a conventional washing process, which can be carried out by means of a household washing machine or by hand.

Suitable synthetic anionic surfactants which are particularly suitable for use in such compositions are the alkyl and / or alkenyl sulfates having 8 to 22 C atoms which carry an alkali, ammonium or alkyl or hydroxyalkyl-substituted ammonium ion as counter cation. Preference is given to the derivatives of fatty alcohols having in particular 12 to 18 carbon atoms and their branched-chain analogs, the so-called oxo alcohols. The alkyl and alkenyl sulfates can be prepared in a known manner by reaction of the corresponding alcohol component with a conventional sulfating reagent, in particular sulfur trioxide or chlorosulfonic acid, and subsequent neutralization with alkali metal, ammonium or alkyl or hydroxyalkyl-substituted ammonium bases. The sulfate-type surfactants which can be used with particular preference include the abovementioned sulfated alkoxylation products of the alcohols mentioned, so-called ether sulfates.

These modified protease variants may also be contained in the agents according to the invention.

In preferred embodiments, the agent of the invention may contain an amylase, more preferably an alpha-amylase. Alpha-amylases are among the most technically important enzymes. An alpha-amylase is an enzyme that catalyzes the hydrolysis of the internal a (1-4) glycoside bonds of amylose, but not the cleavage of terminal or a (1-6) -glycoside bonds. Alpha-amylases are therefore a group of esterases (E.C. 3.2.1.1.). Alpha-amylases catalyze the cleavage of starch, glycogen, and other oligo- and polysaccharides that have a (1-4) -glycoside linkage. In this respect, alpha-amylases counteract starch residues in the laundry and catalyze their hydrolysis (endohydrolysis). The alpha-amylases used in the washing or cleaning agents known from the prior art are usually of microbial origin and are generally derived from bacteria or fungi, for example the genera Bacillus, Pseudomonas, Acinetobacter, Micrococcus, Humicola, Trichoderma or Trichosporon, in particular Bacillus , Alpha-amylases are usually produced by biotechnological methods known per se by suitable microorganisms, for example by transgenic expression hosts of the genera Bacillus or by filamentous fungi.

Furthermore, the agent may be present as a one-component system. Such funds consist of one phase. Alternatively, an agent can also consist of several phases. Such an agent is therefore divided into several components. In principle, the agents can have different states of aggregation. In a preferred embodiment, the washing or cleaning agents are liquid or gel-like agents.

In a particularly preferred embodiment, the agents are present, preferably in liquid form, as a portion in a completely or partially water-soluble coating. Portioning makes it easier for the consumer to dose.

The funds can be packed, for example, in foil bags. Pouches made of water-soluble film make it unnecessary for the consumer to tear open the packaging. In this way, a convenient dosing of a single, sized for a wash portion by inserting the bag directly into the washing machine or by throwing the bag into a certain amount of water, for example in a bucket, a bowl or hand basin, possible. The film bag surrounding the washing portion dissolves without residue when it reaches a certain temperature.

There are numerous processes in the prior art for producing water-soluble detergent portions, which are basically also useful in the context of the present invention. The best known methods are the tubular film processes with horizontal and vertical sealing seams. Also suitable for the production of film bags or dimensionally stable detergent portions is the thermoforming process (thermoforming process). However, the water-soluble envelopes do not necessarily consist of a film material, but can also represent dimensionally stable containers that can be obtained for example by means of an injection molding process.

Furthermore, methods for producing water-soluble capsules of polyvinyl alcohol or gelatin are known, which in principle offer the possibility to provide capsules with a high degree of filling. The methods are based on introducing the water-soluble polymer into a shaping cavity. The filling and sealing of the capsules takes place either synchronously or in successive steps, in which case the filling of the capsules takes place through a small opening in the latter case. The capsules are filled, for example, by a filling wedge, which is arranged above two drums rotating against each other, which have spherical half-shells on their surface. The drums carry polymer belts that cover the ball half-shell cavities. At the positions where the polymer band of one drum coincides with the polymer tape of the opposite drum, a seal takes place. In parallel, the filling material is injected into the forming capsule, wherein the injection pressure of the filling liquid presses the polymer bands in the Kugelhalbschalenkavitäten. A process for the preparation of water-soluble capsules, in which first the filling and then the Sealing takes place, based on the so-called Bottle-Pack ^® method. In this case, a tubular preform is guided into a two-part cavity. The cavity is closed, the lower tube portion is sealed, then the tube is inflated to form the capsule shape in the cavity, filled and finally sealed.

The shell material used for the preparation of the water-soluble portion is preferably a water-soluble polymeric thermoplastic, more preferably selected from the group (optionally partially acetalized) polyvinyl alcohol, polyvinyl alcohol copolymers, polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose and derivatives thereof, starch and derivatives thereof , Blends and composites, inorganic salts and mixtures of the materials mentioned, preferably hydroxypropylmethylcellulose and / or polyvinyl alcohol blends.

The water-soluble thermoplastic used to prepare the portion may additionally optionally comprise polymers selected from the group comprising acrylic acid-containing polymers, polyacrylamides, oxazoline polymers, polystyrene sulfonates, polyurethanes, polyesters, polyethers and / or mixtures of the above polymers. It is preferred if the water-soluble thermoplastic used comprises a polyvinyl alcohol whose degree of hydrolysis makes up 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%.

Examples

Composition of the detergent

Different textiles (cotton fabric and polyester / cotton fabric) were washed with a liquid detergent (formulation 1) and once with a liquid detergent with addition of 1, 0% of a propylene glycol ester (formulation 2).

The different tissues were washed separately at 40 ^° C (in the program Easy care), and 5 washes performed. After 3 washes, it was dried overnight. After 5 washes, the tissue was dried again.

The compound Migoto type BP from Riken was used as the propylene glycol ester. It has now surprisingly been found that these compounds can improve the surface of textiles in detergents. The esters can be easily incorporated into the liquid detergents. measurement method

6 individual samples are ironed twice in different places, which generates an increased sample size per measurement. 12 individual values per measurement are generated. 2 measurements are evaluated.

(Previously, the 3 individual samples were each ironed 5 times in succession on the same ironing path.)

Measurement 1 is carried out on the non-ironed sample = static friction

Measurement 2 on the already ironed sample = dynamic friction

The calculation of the results was carried out as in the tests previously based on DIN EN ISO 13937-2: 2000.

Measurement results

Fabric: SAM Fabric 65% Polyester / 35% Cotton

The differences in cN versus Formulation 1 are shown, taking into account the standard deviations and the requirement for a significance of 10 cN, x> or = 10cN

Where dark = significant value and bright = equal to the standard.

Fabric: SAM Fabric 65% Polyester / 35% Cotton

It can be seen that formulation 2, with the addition of propylene glycol laurate, gives significantly better static and dynamic friction on the blended fabric.
