Description

[Technical Field]

[0001] The present invention relates to a consumer product comprising a plurality of microcapsules, a method for obtaining a consumer product, and the use of a plurality of microcapsules in such a consumer product.

[0002] It is known that encapsulated functional materials are incorporated into consumer products, such as household care, personal care, and fabric care products. Functional materials include, for example, fragrances, flavors, cosmetic ingredients, biocides, substrate enhancers, and nutritional supplements. Microcapsules specifically suited for the delivery of such functional materials are core-shell microcapsules, in which the core contains the functional material and the shell is impermeable or partially impermeable to the functional material. Typically, these microcapsules are used in aqueous media, and the encapsulated functional material is hydrophobic. A wide range of shell materials can be used, however, these shell materials are impermeable or partially impermeable to the encapsulated functional material.

[0003] Among functional materials, fragrances are encapsulated for a variety of reasons. Microcapsules can separate and protect fragrances from suspension media where they are incompatible or unstable, such as consumer product bases. They are also used to aid in the deposition of fragrance components onto substrates, such as skin, hair, fabrics, or hard household surfaces. Furthermore, they can act as a means of controlling the spatiotemporal release of fragrances. These features provide enhanced olfactory benefits that are currently unattainable without microcapsules.

[0004] Thermosetting resins are common shell materials for such fragrance encapsulated products. Core-shell microcapsules formed from aminoplast resins, polyurea resins, polyurethane resins, polyacrylate resins, and combinations thereof are generally quite resistant to fragrance leakage when dispersed in aqueous suspension media, and even when dispersed in surfactant-containing media. The average diameter of these microcapsules is typically 1–100 μm, more specifically 5–50 μm. Microcapsules with such an average diameter may have the disadvantage of impairing the optical aspects of consumer products, such as unstructured liquid detergents, shampoos, and shower gels. Such optical impairment includes the occurrence of turbidity or visible spots in the product. This is particularly problematic when the consumer product is transparent or translucent.

[0005] WO 2016 / 170531 A1 describes nano-sized microcapsules having a diameter smaller than 1 μm, which enable the formation of transparent suspensions. However, the industrial production of nano-sized capsules is known to be difficult, particularly due to the high viscosity of slurries containing such microcapsules in industrially relevant solid content. Furthermore, microcapsules smaller than 1 μm may have a surface-to-volume ratio that is too large to retain the functional material contained in the core or microcapsule over time, especially when the functional material is soluble or volatile in the product base. Therefore, overcoming the aforementioned drawbacks of the prior art is a potential challenge of the present invention. In particular, a potential challenge of the present invention is to provide a translucent or transparent consumer product containing microcapsules that does not suffer from the aforementioned appearance impairment, while still providing the desired olfactory benefits of microcapsules.

[0006] "Transparent consumer products" means products having a turbidity of 50 NTU or less, preferably 20 NTU or less, more preferably 15 NTU or less, and even more preferably 10 NTU or less. The abbreviation NTU represents the Nepherometric Turbidity Unit, a unit of turbidity that is well known to and widely used by those skilled in the art, and is measured using a suitable instrument. "Translucent consumer products" means products having a turbidity between 50 and 350 NTU, preferably between 50 and 300 NTU, more preferably between 50 and 200 NTU, and even more preferably between 50 and 100 NTU. [Overview of the Initiative]

[0007] In a first aspect, the present invention solves the above problems by providing a consumer product comprising a plurality of microcapsules. Each microcapsule comprises a core and a shell surrounding the core. The core comprises at least one functional material. The average total surface area of ​​the plurality of microcapsules contained in one liter of the consumer product is 0.02 to 0.27 m². 2 Preferably 0.02 to 0.12 m 2 That is the case. The applicant has surprisingly found that consumer products containing microcapsules having an average total surface area per liter within the range described above have a turbidity value lower than 350 NTU, i.e., are transparent or translucent, regardless of the corresponding average diameter or the number of corresponding median volumes of the microcapsules. Therefore, the average total surface area of ​​multiple microcapsules contained in one liter of consumer product is an important parameter for obtaining an optimal level of functional material in the consumer product, while still maintaining the consumer product as transparent or translucent.

[0008] In a preferred embodiment of the present invention, the average total surface area of ​​a plurality of microcapsules is determined, in particular, by performing the following steps, based on the average surface diameter D(3,2) of the microcapsules and the volume median diameter D vCalculated based on (50): a) Measure the surface mean diameter D(3,2) (also called the surface volume mean diameter or Sauter diameter) of the microcapsules by static light scattering, and from these, determine the surface mean radius R(3,2) and volume median radius R of the microcapsules. v (50) to obtain; b) Calculate the average surface area Sc of the microcapsules based on the average surface radius obtained in step a).

[0010] e) The average total surface area S of the multiple microcapsules is calculated by multiplying the average surface area of ​​the microcapsules obtained in step b) by the median volume of the microcapsules obtained in step d).

Number

[0011] Regarding the second option of step d), the total volume of the cores present in the consumer product may be formally calculated by dividing the nominal weight m core of the core material added to the consumer product in the form of encapsulated cores by the density ρ core of this core material. The total nominal volume of the shell may be calculated by dividing the nominal weight of the shell material added to the consumer product in the form of the encapsulating shell by the density ρ shell of this shell. The density of the core material may be experimentally measured at 25 °C by using any suitable method known to those skilled in the art, while for the density of the shell material, an estimated density of 1.15 ± 0.1 g / cm 3 at 25 °C may be taken. This covers the density range of the encapsulating materials disclosed later in this specification. Since the shell-to-core weight ratio of the microcapsules is generally less than 0.2, an uncertainty of ±10% may be tolerated in the context of the present invention. Under these conditions, the effect of such uncertainty on the calculated total surface area is less than 2%.

[0012] However, this calculation may be advantageously simplified by considering the fact that the microcapsules generally have a known density ρ caps , for example 1.05 ± 0.05 g / cm 3 at 25 °C, in order to be compatible with the density of the consumer product base. This value may be used to calculate the nominal volume of the microcapsules in Equation 1 to obtain Equation 1b:

Number

[0013] In step a), the average surface diameter D(3,2) and the median volume diameter D of the microcapsule v The static light scattering method used to measure both (50) relates to laser diffraction particle size analysis and Mie scattering theory. The principles of Mie theory and how static light scattering can be used to measure the average diameter and median diameter of multiple particles having a size distribution can be found, for example, in H.C. van de Hulst, Light scattering by small particles. Dover, New York, 1981. Surface average diameter D(3,2) and volume median diameter D v Both of (50) may be calculated by using software provided with a light scattering measurement device.

[0014] In a preferred embodiment of the present invention, the volume central diameter D v (50) is 5 to 50 μm, preferably 8 to 35 μm, and more preferably 10 to 20 μm. Microcapsules with a volume-to-mediate diameter greater than 50 μm are undesirable due to the fact that individual microcapsules of this size may be visible to the human eye, while microcapsules smaller than 5 μm may have an excessively large surface-to-volume ratio for retaining the functional material contained in the core or microcapsule over time, especially if the functional material is soluble or volatile in consumer products. In a specific embodiment of the present invention, the consumer product has a turbidity at 25°C that is lower than 350 NTU, preferably lower than 300 NTU, more preferably lower than 200 NTU, even more preferably lower than 100 NTU, and even more preferably lower than 350 NTU.

[0015] In the context of the present invention, turbidity may also be measured by using a turbidimeter operated in turbidimetric mode, where the intensity of diffused light is measured at an angle of 90°, and this value is divided by the intensity of transmitted light, which is typically measured at an angle of 160° to 180°, depending on the instrument geometry. The incident light may be white light, for example, light emitted by a so-called "white LED" having a wavelength range of 400 to 680 nm. Alternatively, the incident light may be monochromatic light having wavelengths specified in both the visible region of the electromagnetic spectrum, e.g., 460 nm or 650 nm, or the near-infrared region of the electromagnetic spectrum, e.g., 860 nm. Samples with strong coloration are preferably measured using incident light having near-infrared wavelengths.

[0016] In a specific embodiment of the present invention, at least one functional material is selected from the group consisting of fragrances, flavors, and cosmetic ingredients, and is preferably a fragrance. In this specification, "fragrance" means a mixture of fragrance components. "Fragrance component" means a chemical substance (or group of chemical substances) having an odor, which may be used in a fragrance, either alone or in combination with other fragrance components, primarily for the purpose of providing a pleasant scent contribution.

[0017] In a preferred embodiment of the present invention, the core composition comprises at least one fragrance component. A comprehensive list of fragrance components that may be encapsulated according to the present invention can be found in the fragrance literature, e.g., “Perfume & Flavor Chemicals” by S. Arctander (Allured Publishing, 1994). The fragrance encapsulated according to the present invention preferably comprises fragrance components selected from the group consisting of:

[0036] The shell of a microcapsule preferably includes an impermeable encapsulation material that does not allow the functional core material to pass through when the microcapsule is stored in a consumer product. Such impermeable shell materials are well known to those skilled in the art. The shell may contain materials selected from the group consisting of polyurea resins, poly(meth)acrylate resins, polyester resins, polysaccharides, proteins, polypeptides, silicon dioxide, and organosiloxanes, such as aminoplast resins, melamine-formaldehyde resins, urea-formaldehyde resins, and melamine-urea-formaldehyde resins.

[0037] Such microcapsules may be obtained by any method known to those skilled in the art. The size of the microcapsules obtained by such methods may be optimized to a desired value by changing the stirring speed and / or the geometry of the stirrer during the synthesis of the microcapsules, in particular during the emulsification step preceding the formation of the microcapsule shells. For example, aminoplast microcapsules may be obtained as described in EP 2 111 214 B1, Example 3, Sample P4.1; US ​​2018 / 0185808 A1, Example 1; WO 2016 / 207187 A1, Examples 1, 2 and 2b. For example, polyurea microcapsules may be obtained as described in WO 2011 / 160733 A1, Example 2.

[0038] These microcapsules are usually obtained in the form of a slurry, meaning a dispersion or suspension of microcapsules in an aqueous phase. Typically, these slurries may contain 30–50 wt.-% microcapsules, preferably 35–45 wt.-%. The percentage of microcapsules in the slurry is referred to as the “solid content” and is measured experimentally by methods known to those skilled in the art. The solid content of the slurry includes both core and shell material. For example, the solid content may be measured by using a thermobalance operated, for example, at 120°C. The solid content, expressed as a weight percentage of the initial slurry deposited on the balance, may be taken when the drying rate of weight change falls to less than 0.1% / min.

[0039] Preferably, the microcapsules are stabilized against aggregation, creaming, or sedimentation by employing a suspending agent. The suspending agent may be added under stirring before, during, or after the formation of the microcapsules. Preferably, the suspending agent is added to the microcapsule slurry under stirring. The suspending agent may be selected from a broad class of water-soluble or water-dispersible polymers having anionic, cationic, amphoteric, or nonionic characteristics. Water-soluble or water-dispersible polymers useful for the present invention include:

[0040] Polysaccharides, such as starch, modified starch, dextrin, maltodextrin, and cellulose derivatives, and their quaternary forms; natural rubbers, such as alginate esters, carrageenan, xanthan gum, agar, pectin, pectic acid, and natural rubbers, such as acacia gum, tragarant gum, and karaya gum, guar gum, and quaternary guar gum; gelatin, protein hydrolysates, and their quaternary forms; synthetic polymers and copolymers, such as poly(vinylpyrrolidone-co-vinyl acetate), poly(vinyl Alcohol-co-vinyl acetate), poly((meth)acrylic acid), poly(maleic acid), poly(alkyl(meth)acrylate-co-(meth)acrylic acid), poly(acrylic acid-co-maleic acid) copolymer, poly(alkylene oxide), poly(vinyl-co-methyl ether), poly(vinyl ether-co-maleic anhydride), etc., as well as poly(ethyleneimine), poly((meth)acrylamide), poly(alkylene oxide-co-dimethylsiloxane), poly(aminodimethylsiloxane), and their quaternized forms, etc.

[0041] In specific embodiments of the present invention, consumer products may be selected from the group comprising liquid detergents, hard surface cleaners, shampoos, shower gels, liquid soaps, dishwasher liquids, and fragranced products containing ethanol.

The water level in the liquid detergent composition may be less than 50% by weight, more specifically less than 20% by weight, even more specifically less than 10% by weight, and may be as low as 5% by weight. The neutralizing agents that may be used in the detergent composition are preferably organic bases, such as amines, for example monoethanolamine, triethanolamine, organic Lewis bases, and mixtures thereof, but inorganic bases, such as sodium hydroxide, potassium hydroxide, and ammonium hydroxide, may also be used. The level of the neutralizing agent in the composition is typically 6 to 15% by weight of the liquid detergent composition.

[0056] In a second aspect, the present invention provides a method for obtaining consumer products, in particular consumer products as described above herein. The method includes the following steps: a) Product-based selection of transparent or translucent; b) The total surface area of ​​multiple microcapsules contained in 1 liter of consumer product is between 0.02 and 0.27 m². 2 Preferably 0.02 to 0.12 m 2 To achieve this, add multiple microcapsules in the form of a slurry; c) Dispersing multiple microcapsules.

[0057] With respect to step c), the action of dispersing the multiple microcapsules may be carried out by applying a suitable dispersive shear force by any means known to those skilled in the art, such as a propeller, blade mixer, dissolver, rotor starter mixer, low-pressure homogenizer or static mixer. In a third aspect, the present invention provides the use of a plurality of microcapsules in consumer products as described above herein.

[0058] Further features and specific advantages of the present invention will become apparent from the following examples. Example 1 - Formation of aminoplast microcapsules with various diameters Microcapsules were obtained by carrying out the method disclosed in US 2018 / 0185808 A1, Example 1. The volumetric diameter of the microcapsules was varied by changing the stirring speed during emulsification step 3. In this case, the reactor volume was 0.3 L, and the stirrer was a cross-beam stirrer with a pitched beam. Microcapsule volume, central diameter D v (50) and the mean surface diameter D(3,2) were measured using a Malvern Mastersizer 2000S Particle Size Analyzer. A few drops of slurry were added to a circulating stream of degassed water flowing through a scattering cell. Under these dilution conditions, the angular distribution of scattering intensity was measured and analyzed using the dedicated software provided with the device to provide the size distribution of droplets present in the sample, from which the mean surface diameter and volumetric median diameter were obtained.

[0059] The solid content of the slurry was 41-43 wt.-%. In these examples, the density of the microcapsules was 1.04–1.06 g / cm³ at 25°C. 3 I adjusted it to that. [Table 1]

[0060] Example 2 - Formation of a liquid detergent sample containing microcapsules A series of translucent or transparent liquid fabric care detergent samples (HDLDs) were administered in different amounts of the microcapsule slurry obtained in Example 1 at 1.05 g / cm³ at 25°C. 3 Prepared by mixing with a normal, clear, unscented base having a density of (Table 2). Effective amount of microcapsules (m caps The average total surface area of ​​microcapsules in each sample was obtained from the amount of slurry added, based on the measured solid content of these slurries. The density of microcapsules (ρ) was used to determine the average total surface area of ​​microcapsules in each sample. caps ) 1.05 g / cm³ 3 The calculation was performed by taking the value of and applying equation 6.

[0061] The turbidity of the sample was measured at 25°C using a HACH 2100Q iS turbidimeter. The value returned by the instrument was the ratio of the diffuse light intensity measured at a 90° angle relative to the direction of incident light, divided by the transmitted light intensity measured at a 180° angle relative to the direction of incident light. The turbidity value was given in Nephelometric Turbidity Units (NTU). The turbidity values ​​are reported in Table 2. The olfactory performance of the samples was evaluated as follows: 75g of liquid laundry detergent was used in a side-load washing machine (20L capacity, filled with 1kg of terry cloth). The washing cycle was performed at a temperature of 40°C, followed by spin-drying the terry cloth at room temperature for 24 hours. The evaluation was performed by gently rubbing a portion of the terry cloth against another portion of the same terry cloth. The olfactory performance (intensity) was assessed by a panel of four experts and rated on a scale of 1 to 5 (1=barely perceptible, 2=weak, 3=intermediate, 4=strong, 5=very strong).

[0062] [Table 2]

On the other hand, samples outside this range are either cloudy or exhibit insufficient olfactory performance. Furthermore, 0.02-0.12 m³ of microcapsules contained in 1 liter of consumer products... 2 Samples with an average total surface area of ​​these microcapsules specifically exhibit low turbidity values ​​while still possessing good olfactory performance.
