Description

Field of the invention

The invention relates to the use of aqueous emulsions in foam form for the reload of clothing textiles.

State of the art

For the finishing of high-quality textiles, oil blends are increasingly being used which give the textiles skin-care properties. These oil blends, for example, impart moisturizing, smoothing, cooling, warming or moisturizing properties to the skin when absorbed by the textile fabric. For the initial finishing of textiles with oil mixtures, an aqueous emulsion of these oil mixtures, which is further diluted in the textile liquor, is usually used. These aqueous solutions can then be used, for example, in a padding or drawing process for finishing textiles. After a few washes, however, the effect of such original equipment diminishes.

Therefore, there is a need for simple methods which return to the textile the unique characteristics of original equipment.

DE-A-102005045138 describes aqueous microcapsule dispersions comprising a) water, b) microcapsules which are loaded with one or more ingredients or active ingredients, and c) polymeric dispersants, which polymers may be homopolymers or copolymers and wherein these polymers are composed of at least 5 monomer building blocks are. These dispersions of the invention are stable in storage over the long term. These microcapsule dispersions can be used for reload applications.

DE-A-102005059721 describes a process for finishing textiles with nourishing oils which comprises aqueous emulsions having a viscosity of below 200 mPas (measured by Brookfield at 20 ° C.) containing (a) water, (b) one or more nourishing oils and (c) or several emulsifiers applied to textiles, with the proviso that the aqueous emulsion is applied by spraying to the textile. However, this method has the disadvantage that when spraying at least a certain part of the emulsion lands next to the textile material to be treated and is lost.

Description of the invention

Reload is understood in the context of the present invention to reload textiles (for example after washing processes). The reload is therefore not an industrial original equipment of textiles, but it is about to equip the textile again with skin-care oils and / or active ingredients. By its nature, such a reload is carried out in particular by an end user.

The object of the present invention was to develop a process which can be easily applied and which gives the textile the special properties of original equipment with regard to skin-care oils and / or active substances. Another object was to provide aqueous emulsions or dispersions containing skin-care oils and / or active ingredients available, these emulsions or dispersions can easily be foamed with air and form a stable reload foam, the light and even on a textile - in particular items of clothing that are worn directly on the skin, such as underwear, pants, shirts and stockings - distributable and can be incorporated without stains. The Reload foams should be easy to incorporate homogeneously and without staining in the textile. At the same time a fast processability should be guaranteed. For this purpose, it is necessary that the foam on the one hand has sufficient stability to be incorporated into the textile can without first disintegrate and staining On the other hand, the foam should not be so stable that incorporation into the textile is impossible or only possible with considerable expenditure of time. In particular, the reload foam should be incorporated in still-spun textiles, as they are after washing and spinning of textiles, in the manner mentioned.

It is expressly stated that textiles are clothing in the context of the present invention.

and the further proviso that the foam leaving the foam dispenser must meet the following conditions:

• Foam density in the range of 50 to 300 g / l,
• Foam decay time in the range of 2 to 30 min.

The reload foams to be used according to the invention can be emulsions or dispersions. The emulsions may be conventionally prepared O / W emulsions ("macroemulsions") or also known to those skilled in the so-called PIT or micro or nanoemulsions.

Preferred textiles which are provided with the reload foams according to the invention are garments of any kind, preferably those which are worn directly on the skin, such as underwear, pants, shirts and stockings.

• Unter Schaumdichte (SD) ist der Quotient von Schaumgewicht (in Gramm) und Schaumvolumen (in Litern) zu verstehen und zwar bei einer Temperatur von 20 °C. Die SD wird in g/l angegeben. Beispiel: 2 kg einer wässrigen Flotte werden zu 8 Litern Schaum verarbeitet. Die SD beträgt dann 2000 g / 8 1= 250 g/l. Im Rahmen der vorliegenden Erfindung liegt die SD vorzugsweise im Bereich von 50 bis 250 g/l und insbesondere im Bereich von 100 bis 200 g/l.

The foams to be used according to the invention are defined by the two physicochemical parameters mentioned above. To this end, the following should be stated:

• By foam density (SD) is meant the quotient of foam weight (in grams) and foam volume (in liters) at a temperature of 20 ° C. The SD is given in g / l. Example: 2 kg of an aqueous liquor are processed to 8 liters of foam. The SD is then 2000 g / 8 1 = 250 g / l. In the context of the present invention, the SD is preferably in the range from 50 to 250 g / l and in particular in the range from 100 to 200 g / l.

Foam decay time (SZ) is understood to mean the time in which, at 20 ° C., the liquid contained in it has flowed out of a foam volume of 1 liter in an amount of 50 ml. The SZ is a measure of the durability of the foam. The SZ is determined as follows: A graduated conical 1 liter sedimentation funnel (according to DIN 12672-K) is precipitated within 60 s up to the 1000 ml mark with foam. Of the Foam is generated from the aqueous emulsion or dispersion by means of a pump foam bottle. With a stopwatch from then the time is measured in the settle 50 ml of liquid.
The pump foam bottle used is a commercially available manually operated mechanical foam dispenser from Rexam Airspray International BV (bottle 200 ml HDPE - BE-43C1-200HE-10002, Foamer pump white - F202.093.0001).

In the context of the present invention, the SZ is preferably in the range of 5 to 20 minutes and in particular in the range of 7 to 18 minutes.

As stated above, both the foam disintegration time and the foam density are determined at a temperature of 20 ° C.

If desired, the reload foam to be used according to the invention may also contain further constituents. Examples of these are viscosity regulators and plant extracts, which can be used in aqueous or non-aqueous form. In the case of aqueous plant extracts, it is generally possible to dispense with the use of special emulsifiers for these plant extracts. Examples of suitable plant extracts are aloe vera, horse chestnut extract, etc. In the context of the present invention, aqueous plant extracts are preferably used in an amount of 0 to 5%.

foam dispenser

• Schaumdichte im Bereich von 50 bis 300 g/l,
• Schaumzerfallszeit im Bereich von 2 bis 30 min.

In a preferred embodiment, the reload foam to be used according to the invention is applied to the textile material to be finished by means of a manually actuatable mechanical foam dispenser with pump mechanism. For this purpose, any such foam dispenser with pump mechanism can be used per se. The reload emulsions or reload dispersions according to the present invention are foamed with air from a dispenser. However, propellant-based donors are not used in the present invention.
The foam dispenser to be used makes it possible for the user to easily convert the aqueous reload emulsions or dispersions according to the invention into a particularly reload foam which fulfills the above-mentioned complex task. The foam dispenser should be such that it has a mixing ratio of air to liquid (reload emulsion or dispersion) that the generated reload foam meets the two conditions mentioned above, namely:

• Foam density in the range of 50 to 300 g / l,
• Foam decay time in the range of 2 to 30 min.

An example of a suitable foam dispenser is the foam dispenser with pump mechanism from Airspray International BV, as described in US Pat WO-A-03/088941 on page 25ff and Figure 1 is described. Suitable foam dispensers may also be obtained, for example, from Microtec Labs Inc. (5747 Executive Bvld., Dayton, OH 45424, USA).

The reload foam to be used according to the invention is applied directly to the textile fabric and then massaged in. After a drying time, which depends on the type of textile fabric, the textile fabric then has the original skin-care properties and can then be tightened immediately. The skin-care effect can be controlled in the Reload foam according to the invention on the applied amount of nourishing oils or active ingredients. In addition to the skin care properties, the foam can impart the textile to a better feel or smoothness, e.g. tightening tight-fitting garments (e.g., compression stockings).

To the compounds a)

As already mentioned, component (a) is a skin-care oil. The term "oil" is not understood in a chemically limited sense of "triglyceride". Rather, oil is to be understood as a component which has oily consistency at room temperature. Component (a) is preferably selected from the group of monoglycerides, diglycerides, triglycerides and fatty acid alkyl esters. These may be substances of natural origin as well as synthetic substances.

In one embodiment, the oils (a) not only function as skin care substances themselves, but may also contain other oil-soluble skin care substances in dissolved form.

The compounds a) are used in an amount of 0 to 25 wt .-%, preferably 3 to 20 wt .-% and in particular 5 to 15 wt .-%. Examples of particularly suitable oils a) are, for example, coconut oil, squalane, jojoba oil, shea butter, vitamin E, myritol 318, cetiol SN, paraffins, white oils, dimethylsiloxane.

To the microcapsules b)

In the context of the present invention, microcapsules are understood in principle to mean organic polymers having a specific spatial structure (cf. K. Lacasse and W. Baumann, Textile Chemicals, Environmental Data and Facts, Berlin 2004, pages 468-482 ). With regard to the spatial structure, it is true that they are hollow bodies which typically have a diameter in the range of 2 to 2000 μm and an outer diameter in the range of 0.1 to 200 μm and in particular 0.5 to 150 μm. Due to this hollow body structure, the microcapsules may be loaded with ingredients or active ingredients.

In the context of the present invention always loaded microcapsules are used, that is microcapsules which are loaded with one or more ingredients or active ingredients. In principle, all substances which are to be applied to the skin when the textile is loaded with the loaded microcapsules are considered as ingredients or active substances. These may be, for example, fats, oils, plant extracts, vitamins, fragrances, repellants, insecticides and the like. In the oils, vegetable oils with skin-care and health-promoting properties are preferred, such as coconut oil, passion flower oil, shea butter, rose hip seed oil, lavender oil, apricot kernel oil. For the plant extracts algae extracts such as Rhodysterol, Herbalia Centella, Herbalia Green Tea, Herbalia Horse Chestnut and Aloe Vera are preferred. (All Herbalia types are available from Cognis)

Of particular importance in the context of the present invention are those active ingredients or ingredients which have the following properties: skin-care, moisturizing, stimulating, calming, cellulite-reducing, skin-tightening, repellent, refreshing, warming, stimulating.

The encapsulated substances, also referred to below as core material, may consist of any solid, liquid or gaseous materials which are to be incorporated in encapsulated form into corresponding products. Preferably, the core materials used are fragrances, such as perfume oils, or substances which have a nourishing effect in the particular field of use.

As perfume oils or fragrances, individual perfume compounds, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons can be used. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzylformate, e-thyfinethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes, for example, the linear alkanals having 8-18 C atoms. Citral (geranial), citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial and bourgeonal. Among the ketones, for example, the Jonone, a-isomethylionone and methyl cedrylketone to the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, the hydrocarbons include mainly the terpenes such as limonene and α-pinene. Eucalyptol (1,8-cineole) can also be used as the fragrance. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures as are available from vegetable sources, eg pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Also suitable are clary sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, eucalyptus oil, cinnamon leaf oil, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and Sandelhotz oil. In addition, as fragrances nitriles, sulfides, oximes. Acetals, ketals, acids, Schiff bases, heterocyclic nitrogen compounds such as indole and quinoline, pyrazines, Amines such as anthanilates, amides, halogenated organic compounds such as roseacetate, nitrated compounds such as nitro musk, heterocyclic sulfur compounds such as thiazoles and heterocyclic oxygen compounds such as epoxides, all of which are known in the art as possible fragrances are used.

Examples of nourishing components are vitamins and provitamins, such as vitamin A, vitamin C, vitamin E (α-tocopherol), vitamin F (polyene fatty acids), panthenol (provitamin B5), beta carotene (provitamin A) and their derivatives (eg Esters such as stearyl ascorbate), plant extracts, biopolymers, anti-dandruff agents, UV protectants, emollients (cosmetic oils), silicone oils.

In the case of cosmetic applications, tocopherols and their lipid-soluble derivatives are preferred as caring components. Suitable tocopherols are e.g. the natural tocopherols and their mixtures as well as synthetic tocopherols. Suitable derivatives are e.g. Tocopheryl acetate, tocopheryl nicotinate, tocopheryl ascorbate, tocopheryl retinoate, tocopheryl succinate, tocopheryl linoleate or tocopheryl benzoate.

The microcapsules b) are used in an amount of 0 to 25% by weight, preferably 3 to 25% by weight and in particular 15 to 25% by weight.

To the compounds c)

As already stated, the compounds (c) are emulsifiers. These serve to emulsify or disperse the caring oils (a) in water. As such, the choice of emulsifiers is not particularly limited.

The emulsifiers (c) may be conventional synthetic emulsifiers such as surfactants - for example ethoxylated fatty alcohols - or natural emulsifiers such as lecithin. Emulsifiers having an HLB value in the range from 8 to 18 are preferred.

If PIT emulsions are used, preference is given to using special emulsifier mixtures, such as Emulgade SE-PF (manufacturer: Cognis).

In one embodiment, the compounds used are c) polymeric emulsifiers, ie compounds which are to be regarded as structurally polymers and which have an emulsifying effect with regard to the nourishing oils b). Examples of polymeric emulsifiers c) whose monomer units are of natural origin are, for example, polymers based on cellulose (for example Na-carboxymethylcellulose) or polysaccharides (for example xanthan gum, gellan gum, guar or pectins). Example of polymeric emulsifiers c) whose monomer building blocks are of synthetic origin are, for example, acrylates (e.g., Na polyacrylates), methacrylates, or alkyl acrylates (e.g., pemulen). If desired, the monomer units from which the emulsifiers c) are constructed may also be chemically modified. In a very particularly preferred embodiment, the polymeric emulsifiers c) used are compounds selected from the group consisting of xanthan gum, gellan gum, guar and polyacrylates.

These emulsifiers can be used individually or mixed with each other. The emulsifiers c) are used in an amount of 0 to 20 wt .-%, preferably 0 to 15 wt .-% and in particular 0 to 10 wt .-%.

To the compounds d)

The compounds d) are, as already mentioned, foaming agents. There are no limitations per se, but preferably surfactants are used. In particular, good foaming anionic, nonionic, cationic or amphoteric surfactants or mixtures thereof are used.

The compounds d) are used in an amount of 4.1 to 25 wt .-%, preferably 3 to 15 wt .-% and in particular 5 to 10 wt .-%.

Characterization of the foam

By foam density (SD) is meant the quotient of foam weight (in grams) and foam volume (in liters) at a temperature of 20 ° C. The SD is given in g / l.

Foam decay time (SZ) is understood to mean the time in which, at 20 ° C., the liquid contained in it has flowed out of a foam volume of 1 liter in an amount of 50 ml. The SZ is a measure of the durability of the foam. The SZ is determined as follows: A graduated conical 1 liter sedimentation funnel (according to DIN 12672-K) is filled with foam within 60 s up to the 1000 ml mark. Of the Foam is produced from the aqueous emulsion or dispersion by means of the abovementioned pump foam bottle from Rexam Airspray International BV. With a stopwatch from then the time is measured in the settle 50 ml of liquid.

Evaluation of the application and incorporability of the foam

• Das schleuderfeuchte Textil mit einem Feuchtgehalt von 50 ± 20 % wurde mit Schaum beaufschlagt. Die Zahl der Schaumhübe richtete sich nach dem Trockengewicht des Textils und dem Gewicht eines Schaumhubes. Angestrebt wurden 10% ± 5%_Schaumgewicht, bezogen auf das trockene Textil. Die Schaumhübe wurden gleichmäßig auf das Textil verteilt und anschließend per Hand in das Textil einmassiert. Dazu sollte der Schaum ausreichend stabil sein und nicht zu schnell in das Textil eindringen. Die Bewertung des Schaumes erfolgte nach folgendem Schulnotensytem entsprechend folgender Bewertungsskala:

Note Definitionen der Schaumqualitäten 1 Stabiler, feinporiger Schaum, dessen Schaumeigenschaften optimal auf eine gleichmäßige Applikation abgestimmt sind. 2 Stabiler, feinporiger und voluminöser Schaum, der erst nach gleichmäßiger Verteilung in das Textilgewebe eindringt. 3 Stabiler, feinporiger Schaum, der aber tendenziell etwas zu schnell in das Textilgewebe eindringt. 4 Schaum der zwar feinporig ist, aber schnell in das Gewebe eindringt. 5 Grobblasiger, wässriger Schaum, der auf dem Textilgewebe schnell zerfällt und sich nicht gleichmäßig verteilen läßt 6 Schaum zerfällt sofort bei Kontakt mit dem Textilgewebe. Verteilung unmöglich. Fleckenbildung!! The evaluation of the foam for its suitability for reloading was carried out as follows:

• The spun-damp textile with a moisture content of 50 ± 20% was treated with foam. The number of foam strokes was determined by the dry weight of the fabric and the weight of a foam stroke. The aim was 10% ± 5% of foam weight, based on the dry textile. The foam strokes were evenly distributed on the textile and then massaged by hand into the textile. For this, the foam should be sufficiently stable and not penetrate too quickly into the textile. The evaluation of the foam was carried out according to the following school grading system according to the following rating scale:

grade Definitions of foam qualities 1 Stable, fine-pored foam whose foam properties are optimally matched to a uniform application. 2 Stable, fine-pored and voluminous foam, which only penetrates into the textile fabric after even distribution. 3 Stable, fine-pored foam, but tends to penetrate the fabric a bit too quickly. 4 Foam is fine-pored, but penetrates quickly into the tissue. 5 Coarse bubble, watery foam, which quickly disintegrates on the textile fabric and can not be evenly distributed 6 Foam breaks down immediately upon contact with the textile fabric. Distribution impossible. Spotting !!

Foams with the grades 1 to 4 are suitable for the purposes of the present invention for the reload of textiles, foams with grades 5 and 6 not.

Es wurde 5 Minuten durch Rühren mittels eines Flügelrührers homogenisiert. Anschließend wurden weitere 50,0 g vollentsalztes Wasser (Komponente f)) portionsweise zugegeben. Die Mischung wurde auf 80 °C erhitzt, dann ließ man 30 Minuten nachrühren und schließlich ließ man auf Raumtemperatur abkühlen. Es wurde dann abschließend über einen 250 µ Siebbeutel filtriert.20.0 g of the microcapsule dispersion Cognis 2006-G (component b)) were submitted. After adding 20 g of demineralized water (component f)) was homogenized for 15 minutes. The mixture was heated to 50 ° C. Then the following tensides T1, T2 and T3 were stirred in sequence:

• T1) 7.0 g Plantapon LGC sorb (foam-forming surfactant, component d)),
• T2) 2.0 g Plantapon ACG 35 (foam stabilizing surfactant, component e)) and
• T3) 1.0 g of Plantapon LC 7 (foam-stabilizing surfactant, component e)).

It was homogenized for 5 minutes by stirring using a paddle stirrer. Subsequently, a further 50.0 g of demineralized water (component f)) were added in portions. The mixture was heated to 80 ° C, then allowed to stir for 30 minutes and finally allowed to cool to room temperature. It was then finally filtered through a 250 μ sieve bag.

The pump foam was characterized as follows: Brookfiled viscosity at 25 ° C: 30 mPas PH value: 4.8 Foam density (SD) 119 g / l Foam decay time (SZ) 15 minutes

Example 11: Pump foam based on a cosmetic oil

10.0 g Myritol 318 (cosmetic oil, component a)), 7.5 g Nanocream (emulsifier and foaming surfactant, thus components c) and d)) and 1.0 g Phenonip (preservative) were weighed into a beaker and good arises. The mixture (oil phase) was then heated to 60 ° C. with stirring (dissolver disks or propeller stirrer at 150-300 rpm). At 60 ° C, the oil phase was homogeneous and almost clear.

Now, water (component f)) preheated to a temperature of 60 ° C was added in three portions of Pol, P2 and P3 by dropwise addition. During the entire time of dosing the water, the temperature of the system was kept at 60 ° C.

Portion P1 (8.0 g) was slowly added dropwise. After addition of P 1, a viscous intermediate phase which was stirred for a further 5 minutes at 60 ° C. was formed.

Portion P2 (12.0 g) was also added dropwise. The approach became increasingly milky and thinner.

The portion of P3 (61.5 g) was then stirred in relatively quickly.

Finally, the mixture was stirred for 5 minutes and then allowed to cool slowly to below 35 ° C.

The resulting mixture was then filtered through a fine mesh sieve (80μ) to ensure proper functioning of the pump foam bottles used.

The pump foam was characterized as follows: Brookfiled viscosity at 25 ° C: 15 mPas PH value: 7.7 Foam density (SD) 93 g / l Foam decay time (SZ) 8.5 min
