Patent Application
20220168192
The application describes cosmetic cleansing agents in powder form based on anionic surfactants, specific polyols and polysaccharides, which dissolve and foam in contact with water. The application further describes methods for the preparation of the powders and their use for cleansing the human body and/or hair.
Surfactant-containing products for cleansing the human body and hair have been known for a long time and are mainly sold as foam baths, shower preparations, shampoos and/or oral care compositions in liquid or paste form in suitable packaging. End users take the required amount of product from the packaging during use and dispose of it after emptying. Compared to classic soaps that are sold in solid form, such products offer the user the advantage of easy and quick handling, which is why they dominate the market today. However, this advantage is achieved by accepting certain disadvantages, which are discussed below. In most cases, the packaging of the described products in liquid or paste form consists of non-recyclable plastic, which is a serious problem from an environmental point of view in view of the constantly growing amount of plastic waste.
Another problem is that previous products usually contain higher quantities of water or water/solvent mixtures, which means that the products have a larger volume and, possibly of greater importance from a transport point of view, a relatively high weight. This is disadvantageous for several reasons. In times of increasing water scarcity, resources should be saved. An undesirable, increased transport volume associated with large-volume heavy products is also important from an environmental and cost perspective. Another interesting point is that worldwide travel activity is constantly increasing. Consumers are therefore increasingly interested in cosmetic products that are easy to transport due to their low weight and volume. This is particularly relevant with regard to air travel, as larger containers containing liquids are generally excluded from being carried in an aircraft cabin, so that a passenger travelling only with hand luggage often finds himself in the situation, due to the cosmetics products that dominate the market today, of not being able to take his preferred product selection with him or having to decant the corresponding products into smaller containers first, which, however, is generally accompanied by an even greater volume of packaging material.
Providing alternative product forms with very low water content, contained in more environmentally friendly, for example recyclable, packaging to save space, is therefore an important goal in the formulation of improved, contemporary and sustainable cosmetic products.
WO 2019/023332 discloses shampoos in powder form containing substantially sulphate-free surfactants (and other surfactants) and thickening and conditioning agents. However, it turned out that the care effect of such products—especially on very dry, stressed skin and/or on dry, damaged hair—was not always completely satisfactory.
Therefore, there is still a need for cosmetic cleansing agents in powder form which, in addition to the aforementioned requirements, also have improved care properties, especially on very dry, stressed skin and/or on dry, damaged hair.
In view of the problems and requirements described above, the inventors have therefore set themselves the task of providing cosmetic cleansing formulations in powder form which can be produced in an energy-saving manner, are easy to use and in which the use of preservatives can essentially be dispensed with.
In addition to satisfactory cleansing, the powder formulations are also said to have increased conditioning benefits on the skin and/or hair.
The task of the invention is solved by the formulations, methods and uses described in detail below.

Preferred for use in the cosmetic powdered cleansing compositions according to the invention are natural anti-dandruff active ingredients such as the aforementioned plant extracts and/or anti-dandruff active ingredients accessible from natural sources such as propanediol caprylates.
The proportion by weight of antidandruff agents in the total weight of the cosmetic powdered cosmetic powdery cleansing compositions according to the invention is preferably from 0.01 to 5 wt. %, more preferably 0.025 to 4 wt. % and particularly preferably 0.05 to 3 wt. %.
In a preferred embodiment, the cleansing compositions according to the invention in powder form contain—based on their total weight—0.01 to 5% by weight of at least one anti-dandruff active ingredient, preferably a natural anti-dandruff active ingredient and particularly preferably propanediol caprylates.
Further active ingredients, auxiliary substances and additives which may preferably be contained in the powdered cosmetic cleansing compositions according to the invention are, for example:
A significant advantage of the powdered cleaning compositions according to the invention over commercially available concentrates is that no free water needs to be added to them, which means that they have an even smaller volume and preservation is not absolutely necessary.
A small amount of water may nevertheless be present in the powdered cleaning compositions of the invention as a component of commercial products, but preferably they are substantially free of water.
For the purposes of the present invention, “substantially free” of water is preferably understood to mean a maximum water content of 5% by weight, more preferably 3% by weight and particularly preferably 1.5% by weight (based on the total weight of the powdered cleaning compositions according to the invention).
Similarly, it is possible that the powdered cleaning compositions according to the invention nevertheless comprise a small proportion of preservatives as a component of commercial products, but preferably they are substantially free of preservatives.
For the purposes of the present invention, “substantially free” of preservatives is preferably understood to mean a maximum preservative content of 1% by weight, more preferably of 0.5% by weight and particularly preferably of 0.1% by weight (based on the total weight of the powdered cleaning compositions according to the invention).
In a preferred embodiment, the powdered cosmetic cleansing compositions of the invention are substantially free of water and/or preservatives.
The invention also relates to a powdered cosmetic cleansing composition as previously described for the cleansing and/or care of human skin and/or human hair.
It is beneficial and easy for the user to be able to use one and the same product for skin and hair. A composition that is suitable for both due to its formulation and packaging can therefore be considered advantageous.
The invention also relates to a powdered cosmetic cleansing composition as previously described in the form of a powder which dissolves and foams on contact with water.
A powder form is well, namely particularly quickly, soluble. This corresponds to the spirit of the times, but at the same time is associated with a small “wellness experience” during application, as the use of the powder creates a new feeling of application that differs from previous experiences and emphasises the playful side of body care.
The invention also relates to a process for the preparation of a powder cosmetic cleansing composition as previously described, in which all the ingredients are mixed and optionally sieved in a mixing apparatus for powder cosmetic products.
This has the advantage of providing a solid cosmetic cleansing composition in powder form, and the sieving ensures a uniform granulation that is perceived as pleasant. The advantage of such a process is that it does not require melting at high temperatures, which saves energy and is very gentle on the ingredients. This is particularly important when using largely natural, low-processed ingredients that can provide benefits not achievable with highly processed products.
The invention also relates to a process for cleansing the human body and/or hair, in which a cosmetic cleansing agent in powder form, as previously described, is dissolved in water, rubbed and/or foamed between the hands, distributed over the part of the body to be cleansed and rinsed off with water after a contact time of 10 seconds to 15 minutes.
This procedure makes the advantages described above tangible for a user and thus represents an enrichment not only for personal hygiene and care but also a sensory enrichment.
The invention also relates to the use of a cosmetic cleansing composition in powder form, as previously described, for cleansing and/or caring for the human body and/or hair, in particular for improving the
This use makes the advantages described above tangible for a user and thus represents an enrichment not only for personal hygiene and care but also a sensory enrichment.
Another novel form of application of the powder compositions according to the invention, which is associated with a special experience, is packaging, for example in a (paper) sachet or a jar. In addition to the new sensory experience, this is accompanied above all by the advantage of a relatively fast resolution due to a high surface area. The packaging materials glass and paper are easily recyclable packaging materials that are popular with environmentally conscious buyers, and their properties are therefore well suited to the properties of the powdered cosmetic compositions described and claimed here.
It is also possible to fill the powder compositions according to the invention into a jar, for example made of glass. Since the strength of these compositions is in a range that allows an application portion to be taken manually, without a tool, from a crucible intended for multiple applications. If the composition has been foamed in a crucible during its manufacture, the result is a particularly interesting feeling.
