Description

Technical Field

[0001] The currently claimed invention relates to a solid granular material for use in the preparation of personal care products. Additionally, the currently claimed invention relates to a method for preparing the solid granular material. The invention also relates to a kit-in-part containing the solid granular material. Background Technology

[0002] Personal care products, such as sunscreens, shampoos, conditioners, and shower gels, are an ubiquitous part of modern life. The demands on these products are constantly increasing in terms of performance, sustainability, and cost. Long shelf lives are also essential for personal care products, as they are often used for weeks to months; some are primarily used during specific seasons (such as sunscreens) or only at irregular intervals. Meanwhile, many preservatives used in personal care products to extend shelf life are suspected of causing allergic reactions in at least some consumers, leading to growing demand for personal care products containing only small amounts of preservatives or none at all.

[0003] Another issue related to the stability of personal care products is that some active ingredients in these products are water-sensitive, light-sensitive, or heat-sensitive when in solution. Due to this limitation, such active ingredients can only be used in suboptimal amounts or must be completely excluded from the composition.

[0004] Some publications in this field have attempted to address at least some of the aforementioned problems by providing solid cosmetic base materials that can be used to prepare specific types of personal care products on demand.

[0005] EP 0 006 741 A2 describes a self-emulsifying cosmetic base for manufacturing cosmetic compositions in the form of an oil-in-water emulsion. This cosmetic base is provided in a solid form with self-emulsifying properties. The system in EP 0 006 741 A2 has the disadvantage that the base and remaining components must be heated to obtain a personal care product. In the example of EP 0 006 741 A2, a temperature of at least 60°C is required for this step.

[0006] EP 0 754 448 A1 describes a composition that self-emulsifies in water in the form of a homogeneous powder. This powder is obtained from an aqueous plant extract. The powder in EP 0 754 448 A1 may have the disadvantage of generating dust, and the preparation method starting from an aqueous plant extract is not well-suited for water-sensitive components.

[0007] JP 2005343844 A describes a self-emulsifying oily solid composition comprising 8 to 30% by mass of component A as a polyglycerol fatty acid ester and 30 to 92% by mass of component B as an oil component. However, the high oil content in the solid composition of JP 2005343844 A limits its application to a limited range, such as for use in cleansing cosmetics.

[0008] There remains a continued need to develop a material with a long shelf life that overcomes the shortcomings of existing technologies and provides low-cost, sustainable personal care products. Purpose of the invention

[0009] Therefore, an object of the present invention is to provide a material with a long shelf life that produces low-cost, sustainable, and high-performance personal care products. Another object of the present invention is to allow the use of water-sensitive materials in personal care products. A further object is to provide a method for obtaining an emulsion-type personal care product that meets these requirements. Yet another object is to provide a method for obtaining a rinse-free personal care product that meets these requirements. Summary of the Invention

[0010] Some or all of these objectives are achieved through various aspects of the present invention.

[0011] In a first aspect, the present invention relates to a solid granular material for preparing personal care products, characterized in that the solid granular material comprises

[0012] (a) 1.0 to 30.0 wt.% liquid additives,

[0013] (b) 10.0 to 98.0 wt.% of the carrier,

[0014] (c) 0.1 to 50.0 wt.% surfactant,

[0015] (d) Optionally, up to 70.0 wt.% of an active agent,

[0016] Each is based on the total weight of the solid granular material.

[0017] The liquid additive (a) contains a moisturizer.

[0018] Based on the total weight of the solid granular material, the solid granular material contains 1.0 to 30.0 wt.% of the emollient.

[0019] Furthermore, the emollient is selected from the group consisting of: propylene glycol dicaprylate / dicaprate, coconut oil glyceride, caprylic / capric triglyceride, isopropyl myristate, octyl dodecyl myristate, decyl oleate, propyl heptaethyl octanoate, isosorbide dicaprylate, cetearyl isononanoate, octyl octanoate / octyl caprylate, pentaerythritol tetraethylhexanoate, coconut oil-caprylate / capric acid ester, oleyl erucate, isononyl isononanoate, methyl soybean oil, dibutyl adipate, and dibutyl adipate with more than 50% bio-based composition. C12-15 alkyl benzoate, hexyl laurate, ethylhexyl stearate, ethylhexyl palmitate, cetyl palmitate, myristyl myristate, PPG-15 stearyl ether, cocoyl alcohol-octanoate, hexyl decyl laurate, lauryl lactate, dibutyl sebacate, hexyl decyl stearate, octyl dodecyl alcohol, hexyl decanol, tridecane, undecane, n-dodecane, squalane, isododecane, isohexadecane, dioctyl ether, dioctyl carbonate, dipropyl heptyl carbonate, shea butter (shea butter), olive oil, passion fruit seed oil, and mixtures thereof.

[0020] The solid granular material of this invention can be stored for extended periods. Transportation costs are significantly reduced compared to conventional personal care products because the weight of water and other liquids present in conventional personal care products is saved. The granular material of this invention dissolves readily when combined with water by the end user, allowing for the rapid and simple preparation of ready-to-use personal care products, particularly lotion-type and rinse-free personal care products.

[0021] In a second aspect, the present invention relates to a method for preparing the solid granular material of the present invention, wherein the method comprises the following steps:

[0022] a. A liquid additive (a), a carrier (b), a surfactant (c), and optionally an active agent (d) of the solid granular material are mixed to obtain a wet blend, wherein the liquid additive (a) comprises an emollient selected from the group consisting of: propylene glycol dicaprylate / dicaprylate, cocoyl glycerol, caprylic / capric triglyceride, isopropyl myristate, octyl dodecyl myristate, decyl oleate, propyl heptaethyl octanoate, isosorbide dicaprylate, cetearyl isononanoate, octyl octanoate / octyl caprylate, pentaerythritol tetraethylhexanoate, cocoyl octanoate / capric ester, oleyl erucate, isononyl isononanoate, methyl soybean oleate, dibutyl adipate, dibutyl adipate with more than 50% bio-based content, and benzoic acid.

[0023] b. Extrude the wet blend using an extruder to obtain the extruded product.

[0024] c. Crush the extruded product to obtain wet granules.

[0025] d. Dry these wet granules to obtain the solid granular material.

[0026] In a third aspect, the present invention relates to a kit for preparing personal care products, the kit comprising at least a first type of solid granular material of the present invention and a second type of solid granular material of the present invention.

[0027] Preferred embodiments of the above-described solid granular materials are further described in detail below. It should be understood that each preferred embodiment is relevant on its own and in combination with other preferred embodiments. definition

[0028] As used in this specification and the appended claims, unless the context clearly specifies otherwise, the singular form “a / an” also includes the corresponding plural. In the context of this invention, the terms “about” and “approximately” indicate a range of precision that, as will be understood by those skilled in the art, still ensures the technical effect of the discussed features. This term typically indicates a deviation from the indicated numerical value of ±10%, and preferably ±5%. It should be understood that the term “comprising” is not limiting. For the purposes of this invention, the term “consisting of” is considered a preferred embodiment of the term “formed by”. If a group is defined below as including at least a certain number of embodiments, this means that it also includes a group preferably consisting only of those embodiments. Furthermore, the terms “first,” “second,” “third,” or “(a),” “(b),” “(c),” “(d),” etc., in the specification and claims are used to distinguish similar elements and are not necessarily used to describe a sequential or chronological order. It should be understood that the terms thus used are interchangeable where appropriate, and the embodiments of the invention described herein can operate in orders other than those described or shown herein. In cases where the terms “first,” “second,” “third,” or “(a),” “(b),” “(c),” “(d),” “i,” “ii,” etc., refer to steps of a method, use, or experiment, there is no temporal or time interval coherence between these steps, i.e., these steps may be performed simultaneously or there may be time intervals of seconds, minutes, hours, days, weeks, months, or even years between such steps. It should be understood that the invention is not limited to the specific methods, schemes, reagents, etc., described herein, as these can vary. It should also be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of the invention, which will be limited only by the appended claims. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0029] As used herein, the terms “does not contain / comprise” or “does not contain” (unless otherwise stated) mean that the compositions of the present invention do not contain a specific compound or group of compounds (which may be grouped under a collective term), meaning that the composition does not contain more than 0.1% of said compound or group of compounds based on the total weight of the composition. Furthermore, it is preferred that the compositions according to the present invention do not contain more than 0.05% of said compound or group of compounds based on the total weight of the composition. Most preferably, the composition does not contain an analytically measurable amount of said compound or group of compounds.

[0030] When referring to the composition and the weight percentage of the components contained therein, it should be understood that, according to the invention, the total amount of the components does not exceed 100% (± 1%, due to rounding).

[0031] The term "cosmetic composition" refers to any topical product intended for application to the human body for cleansing, beautifying, enhancing attractiveness, altering appearance, or protecting the skin without affecting the structure or function of the body. Within the meaning of this invention, possible cosmetic compositions include leave-in and rinse-off products, such as facial and body care products, including daily care compositions with or without UV protection, as well as sunscreens and sunblock compositions, hair care products such as shampoos, conditioners, shower gels, cosmetic compositions, and similar compositions.

[0032] The term "sunscreen composition" or "sunscreen agent" refers to any topical product that absorbs and can further reflect and scatter some portions of UV radiation. Therefore, the term "sunscreen composition" should be understood to include not only sunscreen compositions but also any cosmetic composition that provides UV protection. The term "topical product" refers to a product applied to the skin and can refer to, for example, sprays, lotions, creams, oils, foams, powders, or gels. According to the invention, sunscreen compositions may contain one or more active agents, such as organic and inorganic UV filters, as well as other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, preservatives, or fragrances.

[0033] The term "daily care composition" refers to any topical product intended for daily use, with or without UV protection. When UV protection is included, it absorbs and can further reflect and scatter UV radiation on certain parts of the body and is used as a daily care product for the human body (e.g., face or body). Daily care compositions may contain one or more active agents, such as organic and / or inorganic UV filters, as well as other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, preservatives, or fragrances. According to the invention, suitable daily care compositions are, for example, leave-on facial and body care products.

[0034] Suitable leave-on products for the face and body include, for example, sunscreens and skin care products.

[0035] Suitable skin care formulations include, for example, moisturizing, anti-aging, improving, and lifting formulations. The listed leave-on compositions can be in the form of creams, ointments, pastes, foams, gels, emulsions, powders, cosmetics, sprays, sticks, or aerosols. Daily care compositions with UV protection safeguard human skin from harmful UV rays.

[0036] As used herein, the term "UV filter" or "ultraviolet filter" refers to an organic or inorganic compound that can absorb and further reflect and scatter UV radiation caused by sunlight. UV filters can be classified as UV-A, UV-B, or broadband filters based on their UV absorbance distribution. Preferably, the term "UV filter" includes any UV filter or a component thereof as defined in Annex VI of Regulation (EC) No. 1223 / 2009 of the European Parliament (version of which date is 11 November 2022).

[0037] The water-soluble UV filter has a solubility in water of at least 2.0% by weight, preferably at least 3.0% by weight, and more preferably at least 5.0% by weight.

[0038] The oil-soluble filter has a solubility of at least 2.0%, preferably at least 3.0%, and more preferably at least 5.0% by weight in a particular emollient.

[0039] The term "sensitive skin" refers to skin whose natural barrier function has been weakened and damaged due to triggering factors. Triggers can be, for example, cold weather, extremely hot water, and key ingredients that may be included in sunscreen or daily care compositions.

[0040] As used herein, the term "Sun Protection Factor (SPF)" indicates the degree to which a sunscreen composition protects the skin from radiation primarily from UV-B. SPF can be measured in vivo using an application amount of 2 mg / cm² (ISO 24444, particularly ISO 24444:2019), or in vitro using, for example, transmittance measurements via a UV-transparent substrate, or via computer simulation (in silico), for example, using a BASF sunscreen simulator. https: / / sunscreensimulator.basf.com / Sunscreen_Simulator / login The method for calculating SPF is also described in the model published by B. Herzog et al. in Simulation of sunscreen performance, Pure Appl. Chem. 2015; 87(9-10):937-951. The sun protection factor (SPF) indicates how long protected skin can be exposed to sunlight without getting sunburned, compared to untreated skin. For example, if a sunscreen composition with SPF 15 is applied evenly to the skin of someone who would normally get sunburned after 10 minutes in the sun, the sunscreen allows that person to remain in the sun for 15 times longer, and therefore for 150 minutes. In other words, SPF 15 means that 1 / 15 of the intense UV radiation will reach the skin, assuming a thick, evenly applied dose of sunscreen at 2 mg / cm².

[0041] The definition of “broadband” protection (also known as broad-spectrum or wide-range protection) can be based on, for example, “critical wavelength” or UVA-PF. For broadband coverage, both UV-B and UV-A protection must be provided. According to US requirements, a critical wavelength of at least 370 nm is needed to achieve broad-spectrum protection. Furthermore, the European Commission recommends that all sunscreen or cosmetic compositions should have a UV-A protection factor (ISO 24443, particularly ISO 24443:2021), which is at least one-third of the stated sun protection factor (SPF). For example, if a sunscreen composition has an SPF of 30, then the UVA protection factor must be at least 10.

[0042] The term "critical wavelength" is defined as a wavelength at which the area under the UV protection curve (protection percentage relative to wavelength) occupies 90% of the total area under the curve in the UV region (290-400 nm). For example, a critical wavelength of 370 nm indicates that the protection of a sunscreen composition is not limited to the wavelength of UV-B (i.e., the wavelength of 290-320 nm), but extends to 370 nm, such that at least 90% of the total area under the protection curve in the UV region is reached at 370 nm.

[0043] The term "application" refers to the act of applying a sunscreen or daily care composition to a person's skin.

[0044] As used herein, the term "solid granular material" refers to a material composed of a collection of discrete, macroscopic solid particles. Solid granular materials possess specific physical properties. These macroscopic solid particles are surrounded by a gas or liquid. Due to the size of solid granular materials, the volume ratio of the solid phase to the fluid phase (liquid or gas) is high, meaning that the macroscopic particles are in close contact with each other. Solid granular materials exhibit typical properties of both solids and liquids: they can withstand deformation and form aggregates like solids, while also flowing like liquids and exhibiting compressibility like general fluids. Solid granular materials are metastable because they are in a static, solid-like state in their ground state, but can flow like fluids when an energy source is provided. All motion of granular materials requires an external energy source to overcome energy losses in particle interactions.

[0045] As used herein, the term "liquid additive" refers to a volatile or non-volatile chemical liquid substance that introduces certain properties into a solid granular material or improves certain properties of the solid granular material. Liquid additives may be introduced before or during the manufacturing process of the solid granular material. According to the invention, the term "liquid additive" comprises a substance selected from the group consisting of humectants, emollients, granulation liquids, and mixtures thereof, or preferably consists of such substances.

[0046] As used herein, the term "humectant" refers to a compound that promotes the attraction and retention of moisture. The term humectant is used herein with its common meaning in the art.

[0047] As used herein, the term "granulation liquid" refers to a volatile or non-volatile liquid added to modify the shape, size, surface area, and / or density of a powder to improve its physicochemical properties and processing. In the preparation of solid granular materials, granulation liquid promotes the wetting and agglomeration of the blend. In this way, granulation liquid provides the blend with optimal properties for forming granular materials.

[0048] As used herein, the term "emollient" refers to a compound that softens the skin and provides a protective barrier against dryness. The term emollient is used herein with its common meaning in the art.

[0049] As used herein, the term "carrier" refers to a compound that provides a general structure to a solid particulate material. A carrier holds other components of a solid particulate material together without reacting with them or external components. The terms "carrier," "carrier material," and "matrix material" are used interchangeably herein.

[0050] As used herein, the term "surfactant" refers to a surface-active agent that reduces surface tension or interfacial tension between two phases (e.g., two liquids, a gas and a liquid, or a liquid and a solid). In this document, a surfactant (also referred to as a surface-active agent) is an amphiphilic molecule comprising a nonpolar hydrophobic portion (typically a straight-chain or branched hydrocarbon chain containing between 8 and 26 carbon atoms) attached to a polar hydrophilic portion. The hydrophilic portion can be nonionic, ionic, or zwitterionic, and in the case of an ionic or zwitterionic portion, may be accompanied by a counterion. The typical mode of action of a surfactant is that the surfactant molecule itself is oriented at the interface between two phases, with the hydrophobic portion oriented towards the hydrophobic phase (e.g., air / oil) and the hydrophilic portion oriented towards the hydrophilic phase (e.g., an aqueous solution). This typically results in a reduction of surface tension or interfacial tension. The term surfactant is used herein with its common meaning in the art.

[0051] As used herein, the term "active agent" refers to a compound in a cosmetic composition that helps to maintain the skin, hair, or other body parts in their natural state and objectively alters or improves the condition of the skin, hair, or other body parts, as well as protect the skin, hair, or other body parts. The term "active agent" is used herein with its common meaning in the art. Examples of such active agents are organic and / or inorganic UV filters, moisturizers, anti-aging agents, conditioning agents, protective proteins, enzymes, vitamins, retinol, or caffeine.

Personal care products obtained from the solid granular material of the present invention provide a smooth feel on the skin without any residual solid particles. The personal care product can be obtained by the end user simply by adding a dissolving solvent (particularly water) from the solid granular material in a preferred amount. In this way, a wide variety of different personal care products can be made from the general core structure of the solid granular material of the present invention. Possible personal care products that can be obtained include sunscreens, hair care products, conditioning agents, facial care products, cosmetic products, body lotions, and toothpaste. Due to the high flexibility regarding additional ingredients and the possibility of producing even small quantities of material, highly personalized and highly specialized personal care products can be provided.

These three components provide the general structure and function of the solid particulate material. Depending on the specific application requirements, these properties can be modified by using specific additional components and by selecting specific liquid additives, carriers, and / or surfactants as discussed below.

[0066] Liquid additives (a)

[0067] The solid granular material of the present invention comprises 1.0 to 30.0 wt.% of a liquid additive based on the total weight of the solid granular material. The liquid additive promotes and assists in the formation of granular material from the blend. The liquid additive is further essential for the structural integrity and stability of the granular material of the present invention.

[0068] Liquid additives (a) contain emollients. Solid granular materials contain an amount of emollient of 1.0 to 30.0 wt.% based on the total weight of the solid granular materials. The emollient is selected from the group consisting of: propylene glycol dicaprylate / dicaprylate, cocoyl glyceride, caprylic / capric triglyceride, isopropyl myristate, octyl dodecyl myristate, decyl oleate, propyl heptaethyl octanoate, isosorbide dicaprylate, cetearyl isononanoate, octyl octanoate / octyl caprylate, pentaerythritol tetraethylhexanoate, cocoyl oleate / caprylate, oleyl erucate, isononyl isononanoate, methyl soybean oleate, dibutyl adipate, dibutyl adipate with more than 50% bio-based content, C12- benzoic acid. 15-alkyl esters, hexyl laurate, ethylhexyl stearate, ethylhexyl palmitate, cetyl palmitate, myristyl myristate, PPG-15 stearyl ether, cocoyl octanoate, hexyl decyl laurate, lauryl lactate, dibutyl sebacate, hexyl decyl stearate, octyl dodecyl alcohol, hexyl decanol, tridecane, undecane, n-dodecane, squalane, isododecane, isohexadecane, dioctyl ether, dioctyl carbonate, dipropyl heptyl carbonate, shea butter, olive oil, passion fruit seed oil, and mixtures thereof.

[0069] The use of emollients allows for the preparation of lotion-type personal care products.

[0070] The emollients particularly preferred according to the invention are selected from C12-15 alkyl benzoate, caprylic / capric triglyceride, dibutyl adipate, propyl heptyl octanoate, dioctyl carbonate and mixtures thereof, with dioctyl carbonate being the most preferred.

[0071] The particularly preferred amount of emollient in the solid granular material is 0.5 to 25.0 wt.%, preferably 2.0 to 20.0 wt.%, more preferably 3.0 to 15.0 wt.%, and even more preferably 3.5 to 10 wt.%, based on the total weight of the solid granular material.

[0072] According to one embodiment of the invention, the liquid additive further comprises a humectant, a granulation solution, or a mixture thereof. Humectants, emollients, and granulation solutions, when used as liquid additives in granular materials, achieve similar but slightly different functions. According to a preferred embodiment, two or all three of these types of liquid additives can be combined in a solid granular material. A variety of different humectants, emollients, and granulation solutions can be used together.

[0073] Any combination of preferred types of liquid additives is possible. According to one embodiment, the solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, wherein the liquid additive is a combination of a humectant and a skin moisturizer. According to another embodiment, the solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, wherein the liquid additive is a combination of a skin moisturizer, a humectant, and a granulation solution. According to yet another embodiment, the solid granular material comprises 1.0 to 30.0 wt.% of a liquid additive, wherein the liquid additive is a combination of a granulation solution and a skin moisturizer.

[0074] The liquid additive is present in the solid particulate material in an amount of 1.0 to 30.0 wt.% based on the total weight of the solid particulate material.

[0143] Properties of solid granular materials

[0144] The solid granular material according to the invention can vary widely in shape, form, size, and structure. According to a particularly preferred embodiment, the solid granular material is in the form of extruded granules. This means that the solid granular material is obtained from an extrusion process. The extruded granular morphology of the solid granular material ensures that no dust is formed, and the solid granular material has good flowability.

[0145] The solid granular material of the present invention exhibits particularly good dissolution properties. According to a preferred embodiment of the invention, 4 g of the solid granular material of the present invention is completely dissolved in 36 g of water at 23°C with a shear rate of 200 / s within less than 180 min, preferably less than 150 min, preferably less than 120 min, more preferably less than 90 min, even more preferably less than 60 min, further more preferably less than 50 min, even more preferably less than 40 min or less than 35 min, very preferably less than 30 min, or most preferably less than 25 min. Therefore, the minimum time for complete dissolution (“complete dissolution”) is defined as the time when the maximum viscosity peak is reached and no solid particles are visible on a macroscopic scale. The method for determining the dissolution properties of the material includes providing 36 g of water in a beaker and adding 4 g of the solid granular material while stirring. Subsequently, the mixture of the solid granular material in water is homogenized at 23°C with a shear rate of 200 / s using a four-blade stirrer.

[0146] The solid granular material of the present invention is preferably pourable and flowable. This property can be described by the flowability of the solid granular material. According to a preferred embodiment of the invention, the solid granular material has a flowability defined as an absolute flow coefficient FLA (also known as FL) of at least 25. An FLA value of 25 indicates a cohesive, loose material.

[0147] The flowability of solid granular materials is preferably determined by measuring the ability of the granules to fall freely through orifices in a disc. This can preferably be done using a powder flowability testing system such as FLDEX. ® Powder Flowability Tester (Teledyne Hanson Flodex) ® The tester is used to perform the test. The system includes a set of discs with different orifice sizes ranging from, for example, 4 mm to 34 mm.

[0148] The methods for determining flowability are detailed in A. Gioia, “Intrinsic flowability: a new technology for powder-flowability classification”, Pharmaceutical Technology Magazine, February 1980.

[0149] The size of solid granular materials can vary over a wide range. According to a preferred embodiment, the solid granular material has a median particle size distribution, Dv50, characterized by laser diffraction, ranging from 0.15 mm to 3.00 mm, preferably from 0.50 mm to 1.50 mm. Many commercial instruments are available for Dv determination using laser diffraction, such as those from Anton Paar (PSA series), Microtrac MRB (Sync), or Malvern Panalytical (Mastersizer series). Depending on the sensitivity and resolution of the instrument chosen, the numerical results characterizing the particle size distribution will vary within a small range. Technicians know how to handle these deviations, and such instruments are commonly used in R&D and quality control laboratories. According to the invention, the Dv50 value is preferably determined by laser diffraction analysis using a Malvern Mastersizer 2000 equipped with a HydroG dispersion unit.

[0150] According to another preferred embodiment of the invention, the solid granular material, preferably in the form of extruded granules, is further spherical or rod-shaped. Particularly preferred is that the ratio of the length (in mm) to the diameter (in mm) of the solid granular material is 1 to 20.

[0151] According to a preferred embodiment of the present invention, the solid granular material for preparing personal care products is used to prepare personal care products as emulsions, particularly O / W or W / O emulsions.

[0152] According to a preferred embodiment of the present invention, the solid granular material used to prepare personal care products is used to prepare rinse-free personal care products.

[0153] According to one embodiment, the solid granular material is not a bath product composition.

[0154] Preparation method

[0155] According to a second aspect of the present invention, the present invention relates to a method for preparing the solid granular material of the present invention. The method of the present invention includes the following steps:

[0156] a.

[0166] One advantage of the solid granular materials of the present invention is that they can provide personalized personal care products. This can be achieved by combining different solid granular materials of the present invention with each other. In this way, a wide range of modified personal care products can be obtained. The first and second solid granular materials of the present invention must differ in at least one aspect, such as in the composition or ratio of the components. There is no limitation on how many different solid granular materials can be combined in the kit of the present invention; however, a typical range is two to five, particularly two to four, different solid granular materials.

[0167] All the details described for solid granular materials also apply to the kit of the present invention, particularly regarding the liquid additives (a), carriers (b), surfactants (c), activators (d), additional additives, and the characteristics of the solid granular materials.

[0180] Prepare 10 g of a homogeneous mixture of lactose (Sigma-Aldrich) and microcrystalline cellulose (Alfaea) in a 1:1 weight ratio as premix 2, and add it to premix 1. The addition should be done slowly to avoid any significant temperature rise in the mixture.

[0181] The mixture was then moistened by adding 1.5 g of deionized water (granulation solution) prior to the extrusion process. The moistened mixture was then extruded using a Caleva Multilab (CML) extrusion system at a rotational speed of approximately 100 rpm. This system comprises a multi-template with 26 orifices of 1 mm in diameter. The same system was used to round the extruded product. After rounding, the granules were dried overnight in a fume hood.
