Description

The present invention is in the field of detergents and cleaning agents and relates to a shaped fragrance body comprising or consisting of a composition which is obtained by contacting the following components: (a) at least one gel former with a molar mass of <2000 g / mol and (b) at least one fragrance. Furthermore, the invention relates to a washing or cleaning agent comprising or consisting of the fragrance molding according to the invention, a method for producing the fragrance molding according to the invention and a use of the fragrance molding according to the invention for scenting surfaces.

Most of the commercially available washing and cleaning agents contain volatile fragrances, so that the fragrance weakens or disappears over time, especially after washing.

In the known fragrance pastilles, which can provide a longer fragrance, these are mostly based on carrier polymers such as Polyethylene glycol (PEG) with an average molecular weight of approximately 2000 to 12000 g / mol and a melting point in the range of 30 to 70 ° C. The carrier material is the main component of the fragrance pastilles and has the disadvantage that due to the very high proportion of PEG in the formulation, high costs are incurred and the environment is additionally polluted.

Furthermore, due to their carrier material, the commercially available fragrance pastilles are often very hard, non-elastic pastilles, which fall apart during transport or if the packaging is shaken more vigorously and lose their original shape.

Fragrance pastilles based on PEG also often have a non-transparent, inhomogeneous appearance, which is due to the presence of undissolved, unevenly distributed solid particles. These properties conflict with the aesthetic perception of the consumer.

There is therefore a need for fragrance pastilles that are based on alternative raw materials and can replace PEG as a carrier polymer. Furthermore, it would be desirable for reasons of sustainability to use carrier materials made from renewable raw materials, for example to reduce wastewater pollution. A reduction in the proportion of the carrier material in the fragrance pastilles would also be desirable.

Surprisingly, it was found that low molecular weight gel formers with a molar mass <2000 g / mol, preferably dibenzylidene sorbitol (DBS), are suitable for forming fragrance moldings, preferably by gelling a perfume emulsion, which overcomes at least one of the disadvantages described above. These fragrance moldings made of elastic, dimensionally stable gels are preferred formed that are translucent and / or transparent. The at least one gel former with a molar mass of <2000 g / mol is more preferably used in an amount of up to 20% by weight, even more preferably of up to 10% by weight.

Mixtures of different fragrances or fragrance compounds are preferably used, which together produce an appealing fragrance for the customer. In order to stimulate the sense of smell, the chemical substance should be at least partially dispersible in the air, i.e. the fragrance should be at least slightly volatile at 25 ° C. If the fragrance is very volatile, the intensity of the smell will quickly fade away. With a lower volatility, however, the odor impression is more sustainable, i.e. it doesn't go away so quickly. In one embodiment, the fragrance therefore has a melting point which is most preferred in the range from -100 ° C to 100 ° C, preferably from -80 ° C to 80 ° C, more preferably from -20 ° C to 50 ° C from -30 ° C to 20 ° C.

To improve the aesthetic impression of the fragrance moldings, it can be colored with suitable dyes. Preferred dyes are known to the person skilled in the art and should have a high storage stability and insensitivity to the other constituents of the fragrance molding or of the washing or cleaning agent and to light and moisture. In addition, the dyes should have little or no substantivity to textile fibers so as not to stain them.

In a further preferred embodiment, the at least one additive contains at least one textile-care compound, which is preferably selected from textile-softening compounds, silicone oils, anti-redeposition agents, optical brighteners, graying inhibitors, anti-shrink agents, anti-crease agents, color transfer inhibitors, antimicrobial agents, germicides, fungicides, Antioxidants, antistatic agents, ironing aids, waterproofing and impregnating agents, swelling and anti-slip agents, UV absorbers and mixtures thereof.

It is preferred that the fabric care compound is a fabric softening compound. It is very particularly preferred that the textile-softening compound is selected from polysiloxanes, textile-softening clays, cationic polymers and mixtures thereof.

The use of polysiloxanes and / or cationic polymers as a textile-care compound in the composition of the fragrance molding is advantageous because they not only have a softening effect, but also enhance the perfume impression on the laundry. The use of softening clays as a textile-care compound in the composition is advantageous because they additionally have a water-softening effect and, for example, limescale deposits on the laundry can be prevented. To achieve optimal performance, it may be preferred that the composition contain a combination of at least two fabric care compounds.

If the composition of the fragrance molding according to the invention contains such textile care compounds, it is used in particular as a detergent / textile care agent or fabric softener or as a component of such an agent or as a component of a detergent.

The compounds of the solvents (c) and additives (d), which may optionally be present in the composition of the fragrance molding, must be different from the at least one gel former (a) and the at least one fragrance (b). The only exception here is water, which can be contained in all components (a) to (d).

In preferred embodiments, compositions are used to produce the fragrance moldings, which form translucent, preferably transparent, dimensionally stable but elastic gels. This gel structure preferably has a strength so that the composition can be brought into a desired shape and this can be maintained under standard conditions (20 ° C., atmospheric pressure), preferably up to 30 ° C., more preferably up to 40 ° C.

The molded body according to the invention is preferably transparent or translucent, particularly preferably transparent. If a molded body according to the invention has a residual light power (transmission) of at least 20% in the spectral range between 380 nm and 780 nm, it is considered transparent in the sense of the invention.

The transparency of the moldings can be determined using various methods. The Nephelometric Turbidity Unit (NTU) is often used as a measure of transparency. It is e.g. Unit used in water treatment for turbidity measurements e.g. in liquids. It is the unit of a turbidity measured with a calibrated nephelometer. High NTU values are measured for cloudy compositions, whereas low values are determined for clear compositions.

The HACH Turbidimeter 2100Q from Hach Company, Loveland, Colorado (USA) is used using the calibration punch StablCal Solution HACH (20 NTU), StablCal Solution HACH (100 NTU) and StablCal Solution HACH (800 NTU) , all of them can also be ordered from Hach Company. The measurement is filled with the composition to be examined in a 10 ml measuring cell with a cap and the measurement is carried out at 20 ° C.

At an NTU value (at 20 ° C.) of 60 or more, shaped bodies have a perceptible cloudiness in the sense of the invention, as can be seen by the naked eye. It is therefore preferred if the fragrance moldings according to the invention have an NTU value (at 20 ° C.) of at most 120, more preferably at most 110, more preferably at most 100, particularly preferably of at most 80.

In the context of the present invention, the transparency of the fragrance moldings according to the invention is determined by a transmission measurement in the visual light spectrum over a wavelength range from 380 nm to 780 nm at 20 ° C. To do this, a reference sample (water, fully desalinated) is first measured in a photometer (Specord S 600 from AnalytikJena) with a cuvette that is transparent in the spectrum to be examined (layer thickness 10 mm). Then the cuvette with filled a sample of the fragrance molding according to the invention and measured again. In the course of sample production, the sample is filled in in liquid form at 80 ° C. and solidified in the cuvette to form the shaped fragrance body and then measured.

It is preferred if the transparent fragrance molding according to the invention has a transmission (20 ° C.) of preferably at least 25%, more preferably at least 30%, more preferably at least 40%, in particular at least 50%, particularly preferably at least 60%.

It is very particularly preferred if the transparent fragrance molding according to the invention has a transmission (at 20 ° C.) of at least 30% (in particular of at least 40%, more preferably of at least 50%, particularly preferably of at least 60%) and an NTU value (at 20 ° C) of at most 120 (more preferably at most 110, more preferably at most 100, particularly preferably at most 80).

A "molded body" is a single body that stabilizes itself in its imprinted shape. This dimensionally stable body is formed from a molding compound (e.g. a composition) by specifically bringing this molding compound into a predetermined shape, e.g. by pouring a liquid composition into a mold and then curing the liquid composition, e.g. as part of a sol-gel process. All conceivable shapes are possible, such as spheres, cubes, cuboids, round disks, prisms, octaders, tetrahedra, egg shapes, dogs, cats, mice, horses, torsos, bust, pillows, automobiles, oval disks with embossed trademarks, and much more others more. The shape of the shaped fragrance body is preferably lenticular or pastille-shaped. This shape can preferably be produced by a pastillation process. In other embodiments, the fragrance shaped body has a desired three-dimensional shape, which is preferably produced by using a prefabricated (casting) shape.

The molded fragrance shaped body preferably has a storage module G 'with 10 ³ Pascal to 10 ⁸ Pascal, more preferably with 10 ⁴ Pascal to 10 ⁶ Pascal, measured with a rotary rheometer using a cone-plate measuring system with a 40 mm diameter and 2 ° opening angle at a temperature of 20 ° C.

The rheological characterization is carried out in the context of this invention using a rotary rheometer, for example from TA-Instruments, type AR G2, from Malvern "Kinexus", using a cone-plate measuring system with a diameter of 40 mm and an opening angle of 2 ° at a temperature of 20 ° C performed. These are shear stress controlled rheometers. However, the determination can also be carried out with other instruments or measuring geometries of comparable specifications.

The measurement of the storage module (abbreviation: G ') and the loss module (abbreviation: G ") (each unit: Pa) was carried out with the equipment described above in an experiment with oscillating deformation. For this purpose, the" stress sweep experiment "is carried out first linear viscoelastic range. Here, the shear stress amplitude is increased at a constant frequency of, for example, 1 Hz. The modules G 'and G "are in a double logarithmic Plot plotted. The shear stress amplitude or the (resulting) deformation amplitude can be plotted on the x-axis. The storage module G 'is constant below a certain shear stress amplitude or deformation amplitude, above which it breaks down. The break point is expediently determined by applying tangents to the two curve sections. The corresponding deformation amplitude or shear stress amplitude is usually referred to as "critical deformation" or "critical shear stress".

To determine the frequency dependency of the modules, a frequency ramp, e.g. between 0.01 Hz and 10 Hz at a constant deformation amplitude. The deformation amplitude must be chosen so that it lies in the linear range, i.e. below the above critical deformation. In the case of the compositions according to the invention, a deformation amplitude of 0.1% has proven to be suitable. The modules G 'and G "are plotted against the frequency in a double logarithmic plot.

Examples Example 1: Production of the fragrance moldings according to the invention in the form of pastilles

Table 1: Compositions of the fragrance pastilles according to the invention (all values given in% by weight) material E1 E2 E3 E4 E5 E6 Glycerine carbonate 42.50 - - - - - Glycerin 42.50 - - - - - Triethylene glycol - 93.37 91.75 90.33 92.34 90.03 Free perfume 5.00 1.63 3.25 2.17 4.33 1.50 Perfume capsule slurry with water (50%) 5.00 - - - - - Dibenzylidene sorbitol 5.00 5.00 5.00 7.50 3.33 8.47 Table 2: Compositions of the fragrance pastilles according to the invention (all values given in% by weight) material E7 E8 E9 E10 E11 E12 Glycerine carbonate - - - 11.31 - - Glycerin - - 22.50 - 11.09 - Triethylene glycol 82.50 90.00 67.50 78.49 80.64 84.20 Free perfume 5.00 2.50 2.50 2.00 1.96 5.40 Perfume capsule slurry with water (50%) 5.00 2.50 2.50 2.00 1.96 5.40 Dibenzylidene sorbitol 7.50 5.00 5.00 6.20 4.35 5.00

The fragrance pastilles are produced by gelling the perfume oil compositions E1 to E12.

With the exception of fragrance capsules (capsule slurry) and free perfume, the ingredients were brought to a temperature of 130 ° C. and mixed with one another. This mixture was then cooled to 70 ° C. and the fragrance microcapsules and the free perfume were added and the mixture was homogenized. This gave a mixture that went well through a pastillation was processable. The liquid mixture was then dripped onto a tempered (23 ° C.) sheet and cooled to ambient temperature. After about 10 minutes, the lozenges produced in this way reached firmness so that they could be filled.

Transparent, homogeneous fragrance pastilles were obtained which were stable up to 40 ° C. The fragrance capsules are soluble in water.

Compared to commercially available fragrance moldings based on PEG, the fragrance moldings according to the invention contain higher water concentrations and lower concentrations of the carrier material (here gelling agent). As a result, smaller amounts of waste are released into the environment because the amount of carrier material can be reduced.

Example 2: Production of the fragrance moldings according to the invention in the form of kittens

With the exception of fragrance capsules (capsule slurry) and free perfume, the ingredients were brought to a temperature of 130 ° C. and mixed with one another. This mixture was then cooled to 70 ° C. and the fragrance microcapsules and the free perfume were added and the mixture was homogenized. The hot solution was then poured into a prefabricated mold and cooled to room temperature for gelation. After the gelling, the kittens were molded and the shaped fragrance articles according to the invention were obtained.

Example 3: Coating the fragrance moldings according to the invention

To avoid a syneresis process (exudation of the gel), the surface of the fragrance shaped bodies according to the invention can be coated with a powdery material (e.g. potato starch), taking into account the water solubility of the shaped bodies. In addition, the moldings according to the invention can be coated with a water-soluble coating.
