Description

Powder composition for cosmetic cleansing of the skin or hair

The application describes a powder composition for cosmetic cleansing of skin or hair based on surfactants and a specific mixture of thickeners, which dissolves quickly upon contact with water and simply transforms into a fluid cleaning agent ready to use. The application also describes a process for producing the powder composition as well as its use for the production of a fluid, cosmetic and ready-to-use cleaning agent.

Products containing surfactants for cleaning the human body and/or hair have been known for a long time and are marketed mainly in the form of bubble baths, shower preparations, shampoos and/or oral care compositions in the form liquid or paste in suitable packaging. During use, end consumers remove the respective quantity of product required from the packaging and dispose of it after emptying it. Compared to conventional soaps marketed in solid form, such products offer the user the advantage of simple and quick handling, which is why they dominate the market today. However, this advantage is achieved by taking into account some disadvantages discussed below. Most of the time, the packaging of the products in liquid or pasty form described is made of non- or poorly recyclable plastic, which constitutes a serious problem from an environmental point of view given the constantly increasing quantity of plastic waste.

Another problem is that today's products generally contain higher quantities of water or water/solvent mixtures, which means that the products have a greater volume and, from a transport point of view, possibly a greater importance, relatively high weight. This is disadvantageous for several reasons. In times of increasing water scarcity, resources should be saved. An undesirable high transport volume associated with heavy and bulky products is also of importance from an environmental point of view, but also from a cost point of view.

Providing alternative product forms with very low water content and compactly contained in more environmentally friendly, e.g. recyclable, packaging is therefore an important goal when formulating improved, modern and sustainable cosmetic products.

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

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

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

For the consumer, this form of use is unusual and possibly also unwanted.

Furthermore, such a form of use also has disadvantages, because, depending on how forcefully the consumer rubs the powder and/or how much water he uses 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.

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 wet hands of the consumer and that it will fall to the ground without being used or that it is rinsed without being used after massaging the foam.

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

There is therefore also a need for powder compositions for cleaning the human body which, in addition to the requirements mentioned above, are easy and practical to use.

Taking into account the problems and requirements described above, the inventors set themselves the goal of developing cosmetic powder compositions for cleaning the human body and/or hair, with which alternative and sustainable product forms can be used flexibly. and with which, in addition to cleaning, excellent care of the human body and/or hair is also ensured.

Lipids can be used in the powder compositions according to the invention, preferably in a weight proportion of 0 to 10% by weight relative to the total weight of the powder composition. Amounts of 0.01 to 8.5% by weight and particularly preferably 0.05 to 7% by weight are preferred.

By suitable protein hydrolysates are meant mixtures of products which can be obtained by acid, base or enzymatic catalyzed degradation of proteins (albumens).

Protein hydrolysates of plant, animal and/or marine origin can be used.

Animal protein hydrolysates are, for example, protein hydrolysates of elastin, collagen, keratin, silk and milk proteins, which can also be present in the form of salts. Such products are distributed for example under the brands Dehylan® (Cognis), Promois® (Interorgana), Collapuron® (Cognis), Nutrilan® (Cognis), Gelita-Sol® (Deutsche Gelatine Fabriken Stoess & Co), Lexein® ( Inolex) and Kerasol® (Croda).

Protein hydrolysates of plant origin, for example soy, almond, rice, pea, potato and wheat protein hydrolysates, are preferred. Such products are, for example, available under the brands Gluadin® (Cognis), DiaMin® (Diamalt), Lexein® (Inolex) and Crotein® (Croda).

Cationized protein hydrolysates may also be used, where the underlying protein hydrolyzate may be derived from animal, e.g. collagen, milk or keratin, plant, e.g. wheat, corn, rice, potatoes, soy or almonds, marine life forms, for example collagen from fish or algae, or protein hydrolysates from biotechnology. The protein hydrolysates on the basis of the cationic derivatives can be derived from the corresponding proteins by chemical hydrolysis, in particular alkaline or acidic, by enzymatic hydrolysis and/or by a combination of the two types of hydrolysis. Protein hydrolysis generally results in a protein hydrolyzate with a molecular weight distribution from approximately 100 daltons to several thousand daltons. Such cationic protein hydrolysates, the underlying protein content of which has a molecular weight of 100 to 25,000 daltons, preferably 250 to 5,000 daltons, are preferred. By cationic protein hydrolysates we also mean quaternized amino acids and their mixtures. The quaternization of protein hydrolysates or amino acids is often carried out using quaternary ammonium salts such as for example the halides of N,N-dimethyl-N-(n-alkyl)-N-(2-hydroxy-3 -chloro-n-propyl)ammonium. Cationic protein hydrolysates can further be further derivatized. Typical examples of cationic protein hydrolysates and derivatives are the products known under the INCI names and commercially available: Cocodimonium Hydroxypropyl Hydrolyzed Collagen, Cocodimonium Hydroxypropyl Hydrolyzed Casein, Cocodimonium Hydroxypropyl Hydrolyzed Collagen, Cocodimonium Hydroxypropyl Hydrolyzed Hair Keratin, Cocodimonium Hydroxypropyl Hydrolyzed Keratin, Cocodimonium Hydroxypropyl Hydrolyzed Rice Protein, Cocodimonium Hydroxypropyl Hydrolyzed Silk, Cocodimonium Hydroxypropyl Hydrolyzed Soy Protein, Cocodimonium Hydroxypropyl Hydrolyzed Wheat Protein, Cocodimonium Hydroxypropyl Silk Amino Acids, Hydroxypropyl Arginine Lauryl/Myristyl Ether HCl, Hydroxypropyltrimonium Gelatin, Hydroxypropyltrimonium Hydrolyzed Casein, Hydroxypropyl trimonium Hydrolyzed Collagen, Hydroxypropyltrimonium Hydrolyzed Conchiolin Protein, Hydroxypropyltrimonium Hydrolyzed Keratin, Hydroxypropyltrimonium Hydrolyzed Rice Bran Protein, Hydroxypropyltrimonium Hydrolyzed Silk, Hydroxypropyltrimonium Hydrolyzed Soy Protein, Hydroxypropyl Hydrolyzed Vegetable Protein, Hydroxypropyltrimonium Hydrolyzed Wheat Protein, Hydroxypropyltrimonium Hydrolyzed Wheat Protein/Siloxysilicate, Laurdimonium Hydroxypropyl Hydrolyzed Soy Protein, Laurdimonium Hydroxypropyl Hydrolyzed Wheat Protein, Lauryldimonium Hydroxypropyl Hydrolyzed Wheat Protein/Siloxysilicate, Lauryldimonium Hydroxypropyl Hydrolyzed Casein, Lauryldimonium Hydroxypropyl Hydrolyzed Collagen, Lauryldimonium Hydroxypropyl Hydrolyzed Keratin, Lauryldimonium Hydroxypropyl Hydrolyzed Silk, Lauryldimonium Hydroxypropyl Hydrolyzed Soy Protein, Steardimonium Hydroxypropyl Hydrolyzed Case in, Steardimonium Hydroxypropyl Hydrolyzed Collagen, Steardimonium Hydroxypropyl Hydrolyzed Keratin, Steardimonium Hydroxypropyl Hydrolyzed Rice Protein, Steardimonium Hydroxypropyl Hydrolyzed Silk, Steardimonium Hydroxypropyl Hydrolyzed Soy Protein, Steardimonium Hydroxypropyl Hydrolyzed Vegetable Protein, Steardimonium Hydroxypropyl Hydrolyzed Wheat Protein, Steartrimonium Hydroxyethyl Hydrolyzed Collagen, Quaternium-76 Hydrolyzed Collagen, Quaternium-79 Hydrolyzed Collagen, Quaternium- 79 Hydrolyzed Keratin, Quaternium-79 Hydrolyzed Milk Protein, Quaternium-79 Hydrolyzed Silk, Quaternium-79 Hydrolyzed Soy Protein, Quaternium-79 Hydrolyzed Wheat Protein.

Moench and Echinacea pallida (Nutt), all kinds of algae, corallines and kelp (such as e.g. the extract of Macrocystis Pyrifera), all kinds of wine and the pericarp of Litchi sinensis.

Suitable extracts can be obtained from the fruits, seeds, flowers, roots, leaves and/or bark of the above-mentioned plants or all plants (algae, kelp).

According to the invention, plant extracts can be used both in pure form and in diluted form. When used in diluted form, they generally contain about 2 to 80% by weight of active substance and, as solvent, the extractant or mixture of extractants used in their production. Suitable extractants are generally water and/or alcohols.

The plant extract(s) can 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% by weight. .5% by weight, the quantity indication referring to the weight of the powder compositions.

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

- vitamins, provitamins and vitamin precursors,

- abrasive substances,

- perfumes, possibly also in capsule form,

- UV filters,

- dyes (natural) intended to color the agent,

- active substances such as bisabolol and/or allantoin,

- complexing agents such as EDTA, NTA, β-alanine-diacetic acid and phosphonic acids,

- antioxidants,

- pH adjustment agents such as citric acid and/or lactic acid,

- preservatives,

- salts (NaCl).

An important advantage of the powder compositions according to the invention compared to commercially available concentrates lies in the fact that it is not necessary to add free water to them, which means that they have an even greater volume. weak.

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.

According to the present invention, the term “substantially free” from 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 (relative to to the total weight of the powder compositions according to the invention).

The invention also relates to a process for producing a powder composition as described above, in which all the ingredients are mixed in a mixing apparatus for powder cosmetic products and optionally sifted.

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

This is advantageous because a solid cosmetic composition is thus available in powder form and sieving guarantees 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 especially important when using minimally processed, largely natural ingredients which can provide benefits not obtainable with highly processed products.

An exciting new form of use of the powder compositions according to the invention, associated with particular experience, is also packaging, for example in a sachet (paper) or a glass. In addition to the new sensory experience, this is accompanied above all by the advantage of relatively rapid dissolution thanks to a high surface area. Glass and paper packaging materials are packaging materials that are well recyclable and popular with environmentally conscious buyers, and whose properties therefore match well with the properties of the powder-form cosmetic compositions described and claimed here.

It is also possible to fill a crucible, for example made of glass, with the powder compositions according to the invention. Because the resistance of said compositions is within a range which allows a portion of use to be taken manually, without tools, from a crucible intended for several uses. If the composition was transformed into foam in a crucible during its production, this gives a particularly interesting sensation.

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

Such use of the powder compositions according to the invention is particularly advantageous, because

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

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

- the rapid dissolution of the powder system in water ensures the simple and rapid provision of a liquid cleaning agent ready for use without the need for high shear, but possibly only with gentle shaking or agitation.

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

- provision of a powder composition described previously,

- mixing the powder composition described above with water in a weight ratio of 1 to 12 in a suitable container,

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

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

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

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