Abstract

Sulphate-free, foaming cosmetic cleaning preparation with an opaque appearance, which is achieved in that the preparation is in the form of an emulsion.

Description

The present invention relates to a sulfate-free, foaming, cosmetic cleaning preparation with an opaque appearance, which is achieved in that the preparation is in the form of an emulsion.

Cleaning products are designed to clean the skin and hair. After the cleaning process, the user ideally has a feeling of cleanliness, freshness and well-being. Humans have always had the need to cleanse themselves, i.e. Remove dirt from the skin or hair. Over time, the cleaning processes have changed, as have the products that are used for cleaning. Nowadays the skin is cleaned, for example, by washing, shower baths or bath tubs, while the hair is often also cleaned during the shower bath or bath tub or also washed separately.

Body cleansing products primarily serve to remove dirt from the skin surface. The dirt film consists of solid or liquid components that have reached the skin from the outside. Excess skin lipids and dead body cells also belong to the dirt film. Due to the surface-active ingredients in the cleaning compositions, the components of the dirt film get into the wash liquor and are removed from the skin by the rinsing process.

Cleaning products for the hair are primarily intended to clean the hair. However, other properties also play an important role. The products should be easy to distribute in the hair, the foam should form quickly, the hair should be cleaned and cared for gently and gently. In addition, it should be easy to wash out and wet hair should have a pleasant feel and be easy to comb. Dry hair should also be easy to comb, the appearance of the hair should be natural and it should shine. The products are said to make the hair supple and not to weigh it down. In addition, rapid relubrication should be prevented. So there is a long catalog of requirements in the area of hair cleaning, which at least to a large extent must be fulfilled in order to be able to sell a product that is accepted by the consumer.

In addition to the product properties mentioned above, the appearance of a cleaning preparation also plays an important role in the acceptance of a product by the consumer. Cleaning preparations in a white color are very attractive to the customer. The white color associates purity and cleanliness. If a white cleaning preparation also has a creamy consistency, the customer also associates good care performance with this product.

Opaque or "white" cleaning compositions are known per se. To give cleaning compositions this appearance, opacifiers or pearlescent agents are generally used. Pearlescent agents can be heavy metal salts of higher fatty acids, fatty acid esters or fatty acid diesters of polyols or fatty acid alkanolamide derivatives. These substances are in the form of crystal platelets or rods and reflect the light. Opacifiers have no pearlescent effect per se. A known and widely used group of opacifiers are sodium salts of a polymer made from styrene monomers with monomers made from acrylic acid, methacrylic acid and / or another olefin and / or one of their esters, e.g. Polymers with the INCI name Styrene / Acrylates Copolymer. Styrene / acrylates copolymer is present in the cosmetic preparations in the form of particles with particle sizes of approximately 170 nm.

This particle size is in the range of the particle size defined by some environmental organizations for the particle size of microplastics. Microplastics can be understood to mean plastic particles that are 5 mm and smaller. These particles can be detected in rivers and seas and are considered harmful to the environment.

It is therefore desirable, when formulating cleaning preparations, to take care not to use substances that could later enter the rivers and seas as microplastic particles.

It was therefore a matter of solving the problem of making opaque, in particular white, cleaning products available, but doing without classic opacifiers, in particular styrene / acrylate copolymer.

This problem can be solved by providing emulsions that are white in appearance and have a creamy consistency. Cleaning emulsions are known per se.

The documents are exemplary DE 102015225003 A1 and DE 102015225005 A1 called, in which a whole series of cleaning emulsions are disclosed. There is no disclosure of foam or foam development in these documents.

The development of foam, especially a creamy, soft foam, is very important for cleaning preparations for cleaning the hair and the body. With a sufficient amount of foam, the consumer usually combines good cleaning performance. A good care performance is often associated with a creamy, soft foam.

This posed the problem that the opaque cleaning preparations, which should be formulated without classic opacifiers, should also generate a sufficient amount of a creamy, soft foam.

The solution to this problem can be to add foam-forming surfactants to the preparations mentioned.

There are notes on this in the document DE 10107216 A1 , which discloses shampoo preparations with lauryl ether sulfate. However, microemulsions must first be made from certain components before the remaining components are added. It is not disclosed that the preparations according to the document mentioned develop foam.

• • einen oder mehrere W/O Emulgatoren,
• • ein oder mehrere Tenside,

Conditioning shampoos are in the document WO 2007/104740 A1 disclosed. These shampoos can be in the form of an emulsion containing an oil phase and a water phase, the emulsion

• One or more polyethoxylated O / W emulsifiers and / or polypropoxylated O / W emulsifiers,
• One or more W / O emulsifiers,
• One or more surfactants,
• One or more oils,
• • contains one or more cationic components.

The shampoo preparations according to WO 2007/104740 A1 are described as foamable.

Nevertheless, there is still a need to provide well-foaming cleaning preparations based on emulsions which are opaque and are easy to produce.

Furthermore, it is desirable to provide sulfate-free preparations. Surfactants containing sulfate are generally characterized by a good cleaning effect and are classified as safe and well tolerated. Nevertheless, it is observed in individual cases that sulfate-containing surfactants in particular can cause skin irritation. It is therefore advisable to avoid products containing sulfate-containing surfactants for sensitive skin, children's and baby skin and for other main problems and skin diseases.

It was therefore also an object of the present invention to provide high-foaming cleaning preparations on an emulsion basis which are distinguished by an excellent mildness and little to no irritation potential of the skin.

The present invention also relates to a process for producing a foaming, opaque cleaning preparation, in which no opacifiers and no pearlescent agents are added to the preparation and the preparation is in the form of an emulsion.

The present invention likewise relates to a method for producing an opaque, stable cleaning preparation in that the preparation comprises at least one O / W emulsifier consisting of a mixture of at least one glyceryl partial ester with fatty acids saturated with C14-C22 and at least one alkali metal salt of a C14-C22 Fatty acid, in particular an emulsifier mixture comprising glyceryl stearate and sodium and / or potassium stearate, is added.

The preparation according to the invention contains emulsifiers. Emulsifiers ensure that two immiscible liquids (e.g. oil in water) can form a stable emulsion. Emulsifiers have an amphiphilic character, some of the molecule is lipophilic, the other hydrophilic. The lipophilic part of the emulsifier is soluble in oil and protrudes into the oil. An oil droplet is formed by stirring and is dispersed in the aqueous environment by the hydrophilic part of the emulsifier. Primarily, emulsifiers have no wash-active, surfactant character.

Emulsifiers reduce the interfacial tension between the two phases and, in addition to reducing the interfacial work, also stabilize the emulsion formed. They stabilize the emulsion formed by interfacial films and by the formation of steric or electrical barriers, thereby preventing the emulsified particles from coalescing.

In order for compounds to be effective as emulsifiers, they must have a certain molecular structure. The structural characteristic of such compounds is their amphiphilic molecular structure. The molecule of such a compound has at least one group with affinity for substances of strong polarity (polar group) and at least one group with affinity for non-polar substances (apolar group).

A distinction is made between nonionic, anionic and cationic emulsifiers. A characteristic of the hydrophilicity of a given emulsifier is its HLB value, which results from the following formula: HLB = 20 x (1- M _lipophilic / M), where M _lipophilic for the molecular weight of the lipophilic portion in the emulsifier and M for the molecular weight of the entire emulsifier.

In general, emulsifiers with an HLB value of up to approx. 8 are considered W / O emulsifiers. O / W emulsifiers, on the other hand, have HLB values of greater than 8 to 15. Substances with HLB values greater than 15 are often referred to as solubilizers.

The preparation according to the invention contains O / W emulsifiers in the form of an emulsifier mixture comprising at least one glyceryl partial ester with fatty acids saturated with C14-C22 and at least one alkali salt of a C14-C22 fatty acid, in particular an emulsifier mixture comprising glyceryl stearate and sodium and / or potassium stearate. The emulsifier mixture contains at least 30% monoglyceride esters, advantageously between 32 and 50%. The content of the alkali salt in the emulsifier mixture is advantageously between 2 and 10% by weight, in particular between 4 and 6% by weight, based on the emulsifier mixture.

Such mixtures are available, for example, with the INCI name Glyceryl Stearate SE and can be obtained as Tegin® from Evonik, as Cutina® GMS SE from BASF and as Imwitor® 960K from Sasol. An HLB value of 12 is given for the emulsifier Glyceryl Stearate SE.

In the preparation according to the invention, the content of O / W emulsifiers in the form of an emulsifier mixture comprising at least one partial glyceryl ester with fatty acids saturated with C14-C22 and at least one alkali salt of a C14-C22 fatty acid is at least 1.5% by weight, preferably 2 to 8% by weight, particularly preferably 3 to 7% by weight, based on the total weight of the preparation. This information relates to the raw material content.

In a further advantageous embodiment, the preparation according to the invention can additionally contain at least one W / O emulsifier. This additional W / O emulsifier is preferably selected from partial esters of polyols with 3 to 6 carbon atoms with saturated C8-C22 carboxylic acids, particularly preferably from glycerol partial esters with saturated C14-C20 fatty acids, particularly preferred is glyceryl stearate, for example under the trade name Tegin M can be obtained from Evonik. This emulsifier has an HLB value of about 4 and can therefore be classified as a W / O emulsifier.

If the preparation according to the invention contains at least one additional W / O emulsifier, this is at least one additional W / O emulsifier in the preparation according to the invention with a total content of 2 to 6% by weight, preferably 3 to 5% by weight. based on the active content and based on the total weight of the preparation.

In addition to the emulsifiers described according to the invention, there are emulsifiers, in particular O / W emulsifiers, which are distinguished by the fact that they contain ethylene oxide residues and / or propylene oxide residues. Ethoxylated and / or propoxylated fatty acids and / or fatty alcohols are often used. For the purposes of the present invention, however, it is advantageous if the preparation according to the invention contains no polyethoxylated and / or polypropoxylated emulsifiers, in particular no polyethoxylated and / or polypropoxylated O / W emulsifiers. The preparation according to the invention is therefore free from ethoxylated and / or propoxylated emulsifiers; the preparation according to the invention is therefore in particular free from ethoxylated and / or propoxylated O / W emulsifiers.

“Free from” in the sense of the present invention means that 0 to 0.1% by weight, preferably 0 to 0.01% by weight, particularly preferably 0% by weight, based on the total weight of the preparation, of the particular Substance present in the preparation.

The preparation according to the invention contains at least one fatty alcohol. Fatty alcohols are e.g. straight or branched chain aliphatic monohydric alcohols with 6 - 22 carbon atoms. Straight-chain fatty alcohols with a chain length of 12-18 C atoms are preferably used in cosmetics. These fatty alcohols are soft, colorless masses, practically non-toxic and well tolerated by the skin. Cetyl alcohol, stearyl alcohol and cetearyl alcohol are of particular importance in cosmetics.

The preparation according to the invention advantageously contains at least one fatty alcohol which is selected from the group consisting of cetyl alcohol, stearyl alcohol and cetearyl alcohol.

The at least one fatty alcohol is advantageously present in the preparation according to the invention with a content of 1.0 to 10.0% by weight, preferably 3.0 to 7.0% by weight, based on the total weight of the preparation.

The preparation according to the invention contains at least one surfactant.

Surfactants can be divided into anionic, cationic, amphoteric and nonionic surfactants.

Anionic surfactants generally have carboxylate, phosphate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in an alkaline or neutral environment. For the purposes of the present invention, however, anionic surfactants which have one or more sulfate groups as functional groups are not present.

The preparation according to the invention contains at least one conditioning agent. Conditioning agents belong to different chemical classes of compounds. However, the conditioners have in common that they interact with the surface of the skin and / or the hair. With regard to hair, conditioners are often described with the term that the conditioners apply to the hair. After the respective preparation has been rinsed out, the conditioning agents should at least partially remain on the hair and thus improve the combability, the feel and the shine of the hair. The conditioning agents can be roughly divided into water-soluble and water-insoluble conditioning agents.

Cationic surfactants and polymers can be added to the water-soluble conditioning agents. Oils, fats, waxes and silicones can be added to the water-insoluble conditioning agents.

It is advantageous if the preparation according to the invention contains cationic polymers as conditioning agents.

Cationic polymers are polymeric compounds which have cationic groups in the main and / or side chain. These groups can be temporarily cationic. These are, for example, primary, secondary or tertiary amine groups which are present as positively charged groups at suitable pH values.

Permanent cationic groups are always positively charged regardless of the pH. It is usually a quaternary nitrogen atom, for example in the form of an ammonium group.

Cationic polymers can be natural polymers which have been modified such that, for example, permanent cationic groups, in particular quaternary ammonium groups, have been introduced into the molecule. Quaternary ammonium groups are preferred cationic groups according to the invention. These groups can be introduced into cellulose molecules or guar molecules, for example.

Cationic guar derivatives are particularly preferred according to the invention in the preparation according to the invention, in particular guar hydroxypropyltrimonium chloride, which is available, for example, under the trade name Jaguar C-14 S from Rhodia.

Cationic polymers can also be synthetic polymers that contain monomers with cationic groups. It is preferred here if the monomer with the cationic group has a permanently cationic group; dimethyl diallyl ammonium chloride is particularly preferred as the monomer. A particularly preferred cationic synthetic polymer is polyquaternium-6, which is available, for example, as Merquat 100 from Lubrizol.

Another particularly preferred synthetic cationic polymer which contains the monomer dimethyl diallyl ammonium chloride in addition to the monomer acrylamide is polyquaternium-7. This polymer is available, for example, as Mirapol 550 P from Solvay.

Ampholytic polymers can also be selected as conditioning agents to be used advantageously. In addition to monomers with a cationic functionality, these polymers also contain monomers with an anionic functionality.
