Description

Title of the invention: Powdered composition for cosmetic cleansing of skin or hair

[0001] The application describes a powdered composition for cosmetic cleansing of the skin or hair, based on surfactants and a specific mixture of thickeners, which dissolves rapidly upon contact with water and is easily transformed into a ready-to-use fluid cleansing agent. The application also describes a process for producing the powdered composition and its use in the production of a ready-to-use, cosmetic, fluid cleansing agent.

[0002] Products containing surfactants for cleansing the human body and / or hair have been known for a long time and are marketed primarily as bubble baths, shower preparations, shampoos, and / or oral care compositions in liquid or paste form in suitable packaging. When using, end consumers dispense the required amount of product from the packaging and dispose of it after emptying. Compared to conventional soaps marketed in solid form, such products offer the user the advantage of quick and easy handling, which is why they currently dominate the market. However, this advantage comes at the cost of certain drawbacks, which are discussed below.Most of the time, the packaging for the described liquid or paste products is made of plastic that is not or only slightly recyclable, which is a serious environmental problem given the ever-increasing amount of plastic waste.

[0003] Another problem is that current products generally contain higher quantities of water or water / solvent mixtures, which means that the products have a larger volume and, from a transport perspective, potentially more importantly, a relatively high weight. This is disadvantageous for several reasons. In times of increasing water scarcity, resources should be conserved. An undesirable high transport volume associated with heavy and bulky products is also important from an environmental perspective, as well as from a cost perspective.

[0004] The provision of alternative product forms with very low water content and contained in a compact manner in more environmentally friendly packaging, for example recyclable, is therefore an important objective when formulating improved, modern and sustainable cosmetic products.

[0005] Shampoos in powder form containing substantially surfactants sulfate-free (and other surfactants), as well as thickeners and conditioning agents, are disclosed in WO 2019 / 023332.

[0006] According to the extract from the Mintel database (Registration ID: 7460103), a facial skin cleansing powder is known which also contains sulfate-free surfactants as well as thickeners and conditioning agents.

[0007] The two powders are rubbed with a little water between the hands and form a foam which is spread on the skin of the face or on the hair.

[0008] For the consumer, this form of use is unusual and, possibly, also undesirable.

[0009] In addition, such a form of use also has disadvantages, because, depending on the force with which the consumer rubs the powder and / or the amount of water used during rubbing to produce foam, the amount of resulting foam and thus the effective amount of cleaning composition applied to the surface of use can vary considerably.

[0010] In addition, this type of use always presents the risk that some of the powder will not produce foam, that it will clump in the consumer's wet hands and fall to the ground without being used or that it will be rinsed off without being used after massaging the foam.

[0011] The practical use of said powders is therefore not always satisfactory.

[0012] There is therefore also a need for powdered compositions for the cleansing of the human body which, in addition to the requirements mentioned above, are easy and convenient to use.

[0013] In view of the problems and requirements described above, the inventors have set themselves the objective of developing cosmetic powder compositions for the cleansing of the human body and / or hair, with which alternative and sustainable product forms can be used flexibly and with which, in addition to cleansing, excellent care of the human body and / or hair is also ensured.

[0187] Suitable plant extracts are primarily extracts of green tea, oak bark, nettle, witch hazel, hops, henna, chamomile, burdock root, horsetail, hawthorn, linden flowers, almond, aloe vera, spruce needles, horse chestnut, date palm, cinnamon, sandalwood, juniper, coconut, mango, apricot, lime, wheat, kiwi, melon, orange, grapefruit, sage, rosemary, birch, mallow, valerian, meadowfoam, wild thyme, yarrow, thyme, lemon balm, bugrane, coltsfoot, marshmallow, meristem, ginseng, coffee, cocoa, moringa, ginger root and Ayurvedic plant extracts such as for example Aegle Marmelos (bilva), Cyperus Rotundus (nagarmotha), Emblica Of-ficinalis (Amalki), Morida Citrifolia (Ashyuka), Tinospora Cordifolia (guduchi), Santalum album, (chandana), Crocus Sativus (kumkuma), Cinnamonum Zeylanicum and Nelumbo Nucifera (kamala), sweet grasses such as wheat, barley, rye, oats, spelt, maize, various varieties of millet (seed millet, finger millet, branch millet as examples), sugarcane, ryegrass, meadow foxtail, tall oatgrass, bentgrass, meadow fescue, purple moor grass,bamboo, cottongrass, pennisetum, Andropogonodeae (Imperata cylindrica also called flammable grass or Cogon grass), buffalo grass, sparta, cynodon, eragrostides, Cymbopogon (lemongrass), Oryzeae (rice), Zizania (wild rice), oat, perennial oats, huulques, breezes, bluegrass, quackgrass and echinacea, in particular Echinacea angustifolia DC, Echinacea paradoxa (Norton), Echinacea simulata, E. atrorubens, E. tennesiensis, Echinacea strigosa (Mc Gregor), Echinacea laevigata, Echinacea purpurea (L.) Moench and Echinacea pallida (Nutt), all kinds of algae, coralline and kelp (such as for example the extract of Macrocystis Pyrifera), all kinds of wine and the pericarp of Litchi sinensis. ,

[0188] Suitable extracts may be obtained from the fruits, seeds, flowers, roots, leaves and / or bark of the aforementioned plants or from the whole of the plants (algae, kelp).

[0189] According to the invention, plant extracts can be used both in pure and diluted form. When used in diluted form, they generally contain about 2 to 80% by weight of the active substance and, as a solvent, the extraction agent or mixture of extraction agents used in their preparation. Suitable extraction agents are generally water and / or alcohols.

[0190] The plant extract(s) may be used in the powder compositions according to the invention preferably in total quantities of 0 to 1% by weight, preferably from 0.001 to 0.75% by weight and in particular from 0.01 to 0.5% by weight, the indication of quantity referring to the weight of the powder compositions.

[0191] Other active substances, adjuvants and additives, which may preferably be contained in the powder compositions according to the invention, are for example:

[0192] - vitamins, provitamins and vitamin precursors,

[0193] - abrasive substances,

[0194] - perfumes, possibly also in capsule form,

[0195] - UV filters,

[0196] - (natural) colorants intended to color the agent,

[0197] - active substances such as bisabolol and / or allantoin,

[0198] - complexing agents such as EDTA, NTA, [3-alanine-diacetic acid and phosphonic acids,

[0199] - antioxidants,

[0200] - pH adjusting agents such as citric acid and / or lactic acid,

[0201] - conservation agents,

[0202] - salts (NaCl).

[0203] An important advantage of the powder compositions according to the invention compared to commercially available concentrates is that it is not necessary to add free water to them, which results in an even smaller volume.

[0204] A small proportion of water may nevertheless be contained in the powder compositions according to the invention as a constituent of commercial products, but they are preferably substantially free of water.

[0205] According to the present invention, "substantially free" of water is understood to mean preferably a maximum water content of 5% by weight, more preferably 3% by weight and particularly preferably 1.5% by weight (relative to the total weight of the powder compositions according to the invention).

[0206] The invention also relates to a method for producing a powdered composition as described above, in which all the ingredients are mixed in a mixing apparatus for powdered cosmetic products and optionally sieved.

[0207] Optionally, the liquid raw materials contained in the powder composition can be simply dosed and mixed with the powder constituents or be sprayed to form the powder constituents.

[0208] This is advantageous because a solid cosmetic composition is thus available in powder form, and sieving ensures a uniform and pleasant grain. The further advantage of such a process is that it is possible to work at high temperatures without melting, which saves energy and is very gentle on the ingredients. This is particularly important when using minimally processed and largely natural ingredients that can offer benefits not obtainable with highly processed products.

[0209] An exciting new use of the powdered compositions according to the invention, combined with a particular experience, is packaging, for example, in a (paper) bag or a glass container. Besides the new sensory experience, this primarily offers the advantage of relatively rapid dissolution thanks to to a high surface area. Glass and paper packaging materials are highly recyclable and popular with environmentally conscious buyers, and their properties therefore correspond well to the properties of the powder-based cosmetic compositions described and claimed herein.

[0210] It is also possible to fill a crucible, for example made of glass, with the powdered compositions according to the invention. Because the resistance of said compositions is within a range that allows a portion to be manually taken, without tools, from a crucible intended for multiple uses. If the composition has been transformed into a foam in a crucible during its production, this provides a particularly interesting sensation.

[0211] The invention also relates to the use of a powdered composition as described above for the production of a ready-to-use, cosmetic, fluid cleaning agent by dissolving the powdered composition in water.

[0212] Such use of the powdered compositions according to the invention is particularly advantageous, because

[0213] - the mixing of the powdered composition with water can be carried out in any (recyclable) container, such as for example a glass or resealable plastic bottle,

[0214] - the user can freely determine the volume of the cleaning preparation usable produced (and, depending on the quantities of powder and water chosen, produce any quantity, from a single quantity to a stock of several liters),

[0215] - the rapid dissolution of the powder system in water ensures the availability simple and quick positioning of a ready-to-use liquid cleaning agent without the need for high shear, but possibly only by shaking or agitating lightly.

[0216] The invention also relates to a method for producing a ready-to-use, cosmetic, fluid cleaning agent, comprising the following steps:

[0217] - making available a powdered composition described above,

[0218] - mixing the powdered composition described above with water in a weight ratio of 1 to 12 in a suitable container,

[0219] - optionally, shaking or stirring the resulting mixture until homogeneous.

[0220] Fluid, cosmetic and ready-to-use cleaning agents obtained using said process have an optimal viscosity for common use in the shower.

[0221] Optimal viscosity is preferably understood to be a viscosity in the range of 2,000 to 11,000 mPas, more preferably from 2,500 to 10,000 mPas and in particular from 3,000 to 9,000 mPas (measured at 20 °C with a Haake VT 550 rotary viscometer, MV measuring system).

[0222] The invention also relates to a cosmetic method for cleansing the human body and / or hair, in which a ready-to-use, cosmetic, fluid cleansing agent obtained according to the method described above is distributed over the part of the body to be cleansed and rinsed off with water after an exposure period of 5 seconds to 15 minutes. This method makes the benefits described above perceptible to a user and thus constitutes an enhancement not only for hygiene and personal care, but also a sensory enrichment.
