Description

"Viscoelastic solid surfactant composition with high surfactant content"

The present invention relates to the technical field of the fixed-shaped

Surfactant compositions for providing surfactant-containing liquors for textile treatment, in particular for cleaning textiles.

Textile treatment agents are usually in solid form (for example as a powder or tablets) or in liquid form (or else as a flowing gel). In particular, liquid detergents or cleaners are becoming increasingly popular with consumers.

Solid textile treatment agents have the advantage that, in contrast to liquid textile treatment agents, they do not require any preservatives and the ingredients contained therein (such as, for example, bleaches or enzymes) can be incorporated more stably. liquid

Forms of supply are increasingly gaining acceptance in the market, in particular due to their rapid solubility and the associated rapid availability of the active ingredients contained therein.

Consumers have become accustomed to conveniently metering pre-portioned engineered fabric treatment agents, such as detergent pouches, and use these products in the form of tablets (solid textile treatment agents) or sachets (also: pillows or pouches) which are typically filled with at least one liquid fabric treatment agent are. However, in addition to the aforementioned advantages, the use of liquids has the disadvantage, for example, that leakages in the bag of the portion cause the liquid textile treatment agent to run out.

Disposable portions in water-soluble bags enjoy popularity with the consumer also because of the attractive appearance of the disposable portion. The appearance of the dosage form is becoming increasingly important. In addition to a good cleaning performance and a sufficient storage stability, a good appearance is one of the reasons for choosing a product. In particular, transparent products are perceived by the consumer as visually appealing. For the

Textile cleaning used solid surfactant compositions are usually opaque. It is therefore also an object to translucent to transparent solid surfactant compositions

provide.

From the point of view of the consumer, it is also desirable to combine the advantages of the forms of solid and liquid preparations and an improved dosage form, especially for liquid or liquid detergents, which is better than the prior art

To provide cleaning agents. For this purpose, a one-time portioning of the components contained must be possible and at the same time a visually pleasing appearance for the consumer, in particular transparency or translucency, can be achieved. In particular, when using solid moldings which have to be dissolved or dispersed for application to a substrate in an aqueous medium, it is particularly important that the solid dissolves well in water. When dosing disposable portions together with the laundry in the drum of the washing machine, the disposable portion must be incorporated quickly into the aqueous liquid liquor, so that in the drum with the molding in contact standing laundry (eg textile) not by permanent over-concentration of the ingredients

Tenside composition suffers damage. It is therefore an object of the invention, solid-form surfactant compositions, especially as a disposable portion in the form of a lumpy

Shaped bodies to provide that dissolve well in contact with water in water or can be dispersed therein.

From the publication WO 02/086074 A1 are viscoelastic, festförmige

Surfactant compositions with a storage modulus of 40,000 to 800,000 Pa known. The viscoelastic surfactant compositions disclosed therein are liquid crystalline

Surfactant phases. The preparation of the viscoelastic surfactant compositions of the prior art is dependent on the phase behavior of the respective surfactants present, which is the

Freedom of formulation with regard to the selection of surfactants and their amounts used

limited.

Another object was thus to provide solid-form surfactant compositions which have a viscoelastic behavior independently of the phase behavior of the surfactants used.

Surprisingly, it has been found that by formulation of a composition containing at least one surfactant and at least one Benzylidenalditol compound in a specific amount, this goal can be achieved.

An object of the invention is therefore as a first embodiment a viscoelastic, solid surfactant composition for textile treatment, containing based on their total weight

and

with the proviso that the composition has a storage modulus between 10 ³ Pa and 10 ⁸ Pa, preferably between 10 ⁴ Pa and 10 ⁸ Pa and a loss modulus (each at 20 ° C, a deformation of 0.1% and a frequency of 1 Hz) and the memory module in the frequency range between 10 ^{~ 2} Hz and 10 Hz is at least twice greater than the loss modulus. More preferably, the composition has a storage modulus in a range of 10 ⁵ Pa to 10 ⁷ Pa.

To further optimize the stability properties of the said composition, it is preferred if the storage modulus is at least five times greater than the loss modulus, more preferably at least ten times greater than the loss modulus (each at 20 ° C, a deformation of 0.1% and a frequency of 1 Hz).

All definitions and preferred embodiments below, unless otherwise defined, apply equally to the first embodiment and the second embodiment.

The viscoelastic, solid surfactant composition incorporates all the advantages of a liquid composition, provides an aesthetic product form with a good dissolution profile in the context of textile treatment with excellent performance profile on the substrate. WO 2010/108002 discloses structured liquid surfactant compositions which contain not more than 1% by weight of a benzylidenalditol compound as a structuring agent. Viscoelastic, solid surfactant compositions containing benzylidenalditol compounds are not described therein.

The viscoelastic, solid surfactant composition of the present invention is storage and dimensionally stable. The said viscoelastic, solid surfactant composition has almost no syneresis even after prolonged storage.

A substance (e.g., a composition) is solid according to the definition of the invention when in the solid state at 20 ° C and 1013 mbar.

As is known and therefore according to the invention, a fabric (e.g., a composition) is viscoelastic and solid when at 20 ° C the storage modulus of the fabric is greater than the loss modulus present. When subjected to a mechanical force on the substance, it exhibits both the properties of an elastic solid and exhibits a viscosity similar to that of a liquid. The terms of the storage modulus and the loss modulus, as well as the determination of the values of these modules, are notoriously familiar to the person skilled in the art (see Christopher W. Macosco, "Rheology Principles, Measurements and Applications", VCH, 1994, pp. 121 ff or Gebhard Schramm , "Introduction to Rheology and Rheometry", Karlsruhe, 1995, p. 156 ff. Or WO 02/086074 A1, p. 2, third paragraph to p. 4, end of the first paragraph).

Theological characterization is in the context of this invention with a

Rotational rheometer, for example TA-Instruments, type AR G2, Malvern "Kinexus", performed using a cone-plate measuring system with 40 mm diameter and 2 ° opening angle at a temperature of 20 ° C. These are

shear stress controlled rheometer. However, the determination can also be made with others

Instruments or measurement geometries of comparable specifications. It is advantageous to solidify the viscoelastic solid composition in the measuring instrument. For this purpose, the sample is prepared in a liquid state outside the meter, then filled into the measuring chamber and solidified therein and then measured. The measurement of the storage modulus (abbreviation: G ') and of the loss modulus (abbreviation: G ") (each unit: Pa) was carried out with the instrumentation described above in an experiment with oscillating deformation.For this purpose, in a stress sweep experiment, the determined linear viscoelastic region. In this case, the shear stress amplitude is increased at a constant frequency of, for example, 1 Hz. The modules G 'and G "are in one

plotted log log plot. On the x-axis can optionally the

Shear stress amplitude or the (resulting) deformation amplitude can be plotted. The memory module G 'is constant below a certain shear stress amplitude or deformation amplitude, above which it collapses. The break point is suitably 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 dependence 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 is in the linear range, i. below the o.g. critical deformation lies. In the case of the invention

Compositions, a deformation amplitude of 0, 1% has proven to be suitable. The modules G 'and G "are plotted against the frequency in a log-log plot.

A substance (e.g., a composition) is liquid according to the definition of the invention when in the liquid state at 20 ° C and 1013 mbar.

A chemical compound is an organic compound when the molecule of the chemical compound contains at least one covalent bond between carbon and hydrogen. This definition applies inter alia to "organic bleach activators" as a chemical compound mutatis mutandis.

A chemical compound is, inversely to the definition of the organic compound, an inorganic compound when the molecule of the chemical compound does not contain a covalent bond between carbon and hydrogen.

In the context of this application for polymeric ingredients specified mean

Molar masses are always, unless explicitly indicated otherwise

weight-average molar masses M _w , which can be determined in principle by means of gel permeation chromatography with the aid of an RI detector, wherein the measurement is expediently carried out against an external standard.

A surfactant-containing liquor in the context of the invention is a liquid preparation obtainable by use of a surfactant-containing dilution with at least one solvent (preferably water) for the treatment of a substrate. As a substrate come tissue or textiles (such as eg clothes) in question. The portions according to the invention are preferably used to provide a surfactant-containing liquor in the course of mechanical cleaning processes, as are carried out, for example, by a washing machine for textiles.

"At least one" as used herein refers to 1, 2, 3, 4, 5, 6, 7, 8, 9 or more In the context of components of the compositions described herein, this indication does not refer to the absolute amount The term "at least one inorganic base" therefore means, for example, one or more different inorganic bases, ie one or more different types of inorganic bases. The amounts given, together with quantities, refer to the total amount of the corresponding type of ingredient.

If, in the context of the application, numerical ranges are defined from one number to another number, then the limit values are included in the range.

If, in the context of the application, numerical ranges are defined between a number and another number, the limits do not include the range.

The compositions of the invention preferably have a flow limit. The yield stress refers to the smallest stress (force per area) above which a plastic substance behaves rheologically like a liquid. It is given in Pascal (Pa).

The flow limit of the compositions was measured using a rotary rheometer from TA-Instruments, type AR G2. This is a so-called

Schubspannungskontrolliert.es rheometer. For measuring a yield point with a

shear stress controlled rheometers are various methods in the literature

described to those skilled in the art.

For the determination of the yield points in the context of the present invention, the following was carried out at 20 ° C:

The samples were loaded in the rheometer in a "stepped-flow procedure" with a gradually increasing shear stress σ with time

Shear stress in the course of 10 minutes with 10 points per shear stress decade from the smallest possible value (eg 2 mPa) to eg 10 Pa can be increased. The time interval is chosen such that the measurement is carried out "quasi-statically", ie that the deformation of the sample can be brought into equilibrium for every given shear stress value.As a function of this shear stress, the equilibrium deformation γ of the sample is measured plotted log plot against the shear stress If the investigated sample has a yield point, you can clearly see two areas in this plot differ. Below a certain shear stress, one finds a purely elastic one

Deformation according to Hooke's law. The slope of the curve γ (σ) (log-log plot) in this area is one. Above this shear stress, the flow range begins and the slope of the curve is suddenly higher. The shear stress at which the bending of the curve takes place, ie the transition from the elastic to a plastic deformation, marks the yield point. A convenient determination of the break point is possible by applying tangents to the two curve parts. Samples without yield point do not show a characteristic kink in the function γ (σ).

The solid-form viscoelastic composition of the present invention preferably has a yield value in the range of 2.5 to 100 Pa, more preferably 3 to 80 Pa, as measured by rotational rheometer, 40 mm diameter cone-and-plate measuring system and 2 ° opening angle at a temperature of 20 ° C.

The viscoelastic, solid surfactant composition according to the invention is preferably transparent or translucent. A mixture according to the invention in the spectral range between 380 nm and 780 nm has a residual light power related to the reference measurement

(Transmission) of at least 20%, it is considered transparent in the context of the invention.

The transparency of the surfactant composition according to the invention can be determined by various methods. The nephelometric turbidity unit (NTU) is often used as a measure of transparency. It is a e.g. unit used in water treatment for turbidity measurements, e.g. in liquids. It is the unit of turbidity measured with a calibrated nephelometer. High NTU values are measured for cloudy surfactant compositions, while low values are determined for clear, transparent surfactant compositions.

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

At an NTU value (at 20 ° C.) of 60 or more, surfactant compositions which can be recognized by the naked eye in the sense of the invention have a perceptible haze. Therefore, it is preferred that the surfactant compositions of the invention have an NTU (at 20 ° C) of at most 120, more preferably at most 1 10, more preferably at most 100, most preferably at most 80. In the context of the present invention, the transparency of the solid-state agents according to the invention was determined by a transmission measurement in the visual light spectrum over a wavelength range from 380 nm to 780 nm at 20 ° C. For this purpose, first a reference sample (water, demineralized) in a photometer (Fa. Specord S 600 from Analytikjena) with a transparent in the spectrum to be examined cuvette (layer thickness 10 mm) measured. Subsequently, the cuvette with a sample of the invention

Filled surfactant composition and measured again. The sample is filled in the liquid state and solidified in the cuvette and then measured.

Corresponding portions of this embodiment are well known to those skilled in the art as pouch products.

A chamber is a wall delimited by walls (eg by a film), which can also exist without the material to be dispensed (possibly changing its shape). A layer of a surface coating thus does not explicitly fall under the definition of a wall. The water-soluble material in a pouch forms the walls of the chamber and thereby envelops the compositions of the fabric treatment agent. Soluble in water is a material, if at 20 ° C 0.1 g of the material with stirring (stirring speed magnetic stirrer 300 rpm, stirring bar: 6.8 cm long, diameter 10 mm, beaker 1000mL low form the company.

Said framed film is immersed in 800 mL of distilled water heated to 20 ° C in a 1 liter beaker with a circular bottom surface (Schott, Mainz, 1000 mL beaker, low mold) so that the surface of the clamped film is at right angles to the Bottom surface of the beaker is arranged, the upper edge of the frame is 1 cm below the water surface and the

Lower edge of the frame is aligned parallel to the bottom surface of the beaker such that the lower edge of the frame along the radius of the bottom surface of the beaker and the center of the lower edge of the frame is located above the center of the radius of the beaker bottom. The material should dissolve with stirring (stirring speed magnetic stirrer 300 rpm, stirring bar: 6.8 cm long, diameter 10 mm) within 600 seconds in such a way that with the naked eye, no single solid-shaped film particles are more visible.
