Definitions

  • the present invention relates to the use of a fragrance-containing microcapsule-containing textile detergent in textile treatment for improving the fragrance of the textiles treated therewith after they have been dried in a machine dryer.
  • Suitable devices for this purpose are e.g. the so-called exhaust air dryer, condensation dryer, dryer with heat pump and the washer dryer, which represent a combination of the dryer with a washing machine in a device.
  • a disadvantage of using such clothes dryers is that the intensity and quality of the fragrance of the textiles to be dried, which has previously been applied, for example, by the use of fragrance-containing detergent and / or softener, suffers from the drying process, is usually even considerably reduced, so that the dried textile usually does not have the previous intensity and quality of the fragrance.
  • the object of the present invention was therefore to make it possible for the consumer to achieve the highest possible intensity and quality of the fragrance even of the dried laundry after the textile washing or treatment and machine textile drying.
  • the object of our invention is the use of a fabric-containing microsphere-containing fabric rinse in the textile treatment to improve the fragrance of the treated textiles after drying in a machine dryer.
  • the improvement preferably relates to the comparison to a textile rinse, which otherwise corresponds to a textile rinse aid according to the invention, with the difference that it contains no microencapsulated fragrances.
  • the inventive improvement of the fragrance of the treated textiles after drying in a machine dryer can readily by trained professionals, preferably perfumers, are determined by odor assessment of the treated textiles.
  • Fabric rinsing agent is the generic term for such agents which at least do not serve primarily or at least not primarily for textile cleaning, but generally act as after-treatment agents - e.g. as an additive in the last rinsing bath or for application after washing - such as softener and fabric conditioner.
  • These may be in liquid dosage form, which is more preferred, but may also be solid dosage form, which may be e.g. water-soluble or water-dispersible particles (which may serve, for example, as carrier material for active substances), e.g.
  • Particles selected from the group consisting of inorganic alkali metal salts, organic alkali metal salts, inorganic alkaline earth metal salts, organic alkaline earth metal salts, organic acids, carbohydrates, silicates, urea or mixtures thereof, which particles may preferably be in the form of crystals.
  • Fabric rinses may e.g. in a usual automatic washing process in the last rinse, as e.g. the fabric softener and with corresponding textile aftertreatment agents is usually the case.
  • Almost all automatic washing machines have a separate "softener" compartment, from which the agent is then automatically introduced into the washing chamber in the last rinse cycle, but the use according to the invention of the textile rinse is not necessarily coupled to the use of an automatic washing machine
  • the decisive factor is merely that a treatment liquor is prepared by adding a fragrance-containing microcapsules containing textile detergent, such as a fabric softener, with which the textile to be treated can come into contact, whereupon fragrance-containing microcapsules
  • the resulting moist textile is then subjected to drying in a machine-type tumble drier, resulting in fragrance effects
  • the textile rinse agents to be used can also contain other active substances, such as eg Fabric softening substances, which are also described in more detail below, but this is not absolutely necessary.
  • the term “upon removal from the dryer” is meant the period which immediately follows the completion of the machine drying process, ie when the consumer opens the dryer, removes the laundry and, for example, collapses it, for example to iron it or around it This period is of particular importance for the well-being of the consumer, because he sees the overall process of "textile washing” as complete.
  • the textile is now prepared so that it is back in the sense of need At this point in time, the consumer wishes to be able to perceive and enjoy a pleasant scent of the textiles, but the disadvantage is that in the dryer application, the fragrance of the laundry, even with the previous use of perfumed fabric softener in the laundry Compared to the still wet, freshly washed laundry is usually already significantly reduced.
  • the object of our invention now makes it possible to improve the fragrance of the textiles after they have been dried in a machine dryer, in particular as regards the intensity and the pleasantness of the fragrance.
  • a preferred embodiment of the invention is when the use of the invention is directed to the improvement of the pleasantness of the textiles after drying in a machine dryer on removal from the dryer.
  • This improvement may e.g. can be achieved when taking a concrete perfume-containing textile rinse, such as a conventional fabric softener, and reshaping it so that at least a portion of the fragrance contained in microencapsulated form, without the total amount of the fragrance contained, based on the total agent, would have to be increased.
  • a concrete perfume-containing textile rinse such as a conventional fabric softener
  • fragrance of the dried laundry can be improved, but that it is also possible that the fragrance of freshly washed, wet laundry is not reduced, although the absolute amount of the fragrances used remains the same.
  • the total amount of fragrances contained must therefore not be increased, but only a proportion of fragrances must be present in microencapsulated form, on the one hand to be able to obtain the odor result of the wet laundry and on the other hand to improve the odor result of machine-dried laundry.
  • the fragrance of the machine-dried textile improved at the stage of removal from the dryer, but also the durability of the fragrance the textiles can be improved after drying in a machine dryer.
  • the fragrance thus remains noticeable for a longer time, preferably over days to weeks.
  • a washing and / or rinsing process is first carried out using the fragrance-containing microcapsule-containing textile rinsing agent in an automatic washing machine and then followed by drying of the moist textile in a machine drier.
  • drying temperatures of the tumble dryer in the range 35 to 8O 0 C., preferably 4O 0 C to 75 0 C.
  • the residual moisture of the dried textile after the machine drying process is ⁇ 25%, preferably ⁇ 22%, based on the dry weight of the textile.
  • a residual moisture of e.g. 22% means that per kg of laundry (dry weight) still 220 g of water are bound.
  • the residual moisture content of cotton after washing and spinning, ie before drying, is usually between about 50-70%, depending on the intensity of the spinning process.
  • the residual moisture of the dried textile after the drying process is preferably even ⁇ 17%, advantageously ⁇ 10%, more advantageously ⁇ 6% and in particular ⁇ 2%.
  • the residual moisture can be adjusted with the usual tumble driers usually targeted effortlessly. These devices have humidity control, with sensors in the device measuring the humidity of the laundry so that the drying process continues until the desired final moisture level is reached. In general, however, at least 4 degrees of drying are adjustable in the currently used dryers, such as "lack of moisture”, “ironing”, “cupboard dry” and “extra dry”. These degrees of drying are associated with corresponding residual moisture of the textile.
  • “Lackfeucht” usually corresponds to a residual moisture of about 20%
  • "ironing iron” usually corresponds to a residual moisture of about 15%
  • cupboard dry usually corresponds to a residual moisture content of about 2-4%
  • extra dry usually corresponds to a residual moisture content of ⁇ 2 %, whereby the degree of drying or residual moisture may of course vary slightly depending on the device.
  • the desired drying level (or residual moisture), however, can be easily realized even with devices without humidity control. This can be achieved by setting the dryer to a fixed drying time, which depends on the amount and humidity of the However, laundry can be different. Here are the experience of the consumer with his individual devices and customs (eg setting the spin speed in the previous textile laundry) to bear. After expiry of this time control, the consumer can easily check whether the desired degree of drying has already been achieved and possibly set a time extension. The consumer is already clear that he can control the degree of dryness or the residual moisture, because experience has shown, for example, laundry that is still to be ironed, be moister than laundry that comes directly into the closet.
  • washing and / or rinsing process by hand (hand washing) or simply to use a soaking bath (ie soaking the laundry in a vat), for example, followed by drying of the damp textile in a machine dryer, preferably as regards the parameters residual moisture and drying temperature, as mentioned above.
  • the textile rinse aid used according to the invention contains more than 15% by weight, preferably more than 20% by weight, in particular more than 25% by weight, of microencapsulated fragrances having a ClogP value > 4.0, wt .-% based on the total amount of microencapsulated fragrances.
  • microencapsulated fragrances or "encapsulated fragrances” means in the context of the invention in each case the fragrances which are contained in the microcapsules.
  • the ClogP value is now also well known to the person skilled in the art from the patent literature. It is due to the octanol / water partition coefficient.
  • the octanol / water partition coefficient of a perfume ingredient is the ratio between its equilibrium concentration in octanol and in water. Since the distribution coefficients of the perfume ingredients are often high, e.g. 1000 or higher, they are more conveniently given in the form of their base 10 logarithm, which is referred to as the so-called Iog-P value.
  • the logP value of numerous fragrances is documented; For example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc., (Daylight CIS), Irvine, California, contains numerous logP values, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP” program, which is also available from Daylight CIS. This program also lists the experimental logP values if they are available in the Pomona92 database. The "calculated logP" (this is the ClogP value) is determined by the Hansch and Leo fragment approach (see A. Leo, Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, PG Sammens, JB Taylor and CA Ransden, Eds., P.

Abstract

Les textiles séchés dans un sèche-linge présentent en règle générale des inconvénients en termes d'odeur par rapport au linge humide fraîchement lavé et qui s'est imprégné des parfums de la lessive et/ou de l'adoucissant employé. La présente invention décrit comment, en utilisant un agent de rinçage pour textiles contenant des microcapsules parfumées pour traiter le linge, on obtient une amélioration de l'odeur des textiles ainsi traités après avoir été séchés dans un sèche-linge.
