Foaming cleaning preparation based on an emulsion

The present invention relates to a 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. The components of the dirt film get into the wash liquor through surface-active ingredients in the cleaning compositions 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 has to 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 for 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 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 exist as crystal platelets or rods and reflect the light. Opacifiers have no pearlescent effect per se. A known and frequently used group of opacifiers are sodium salts of a polymer of styrene monomers with monomers of acrylic acid, methacrylic acid and / or another olefin and / or one of their esters, e.g. Polymers with the INCI name Styrene / Acrylates Copolymer. Styrenes / 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 providing opaque, in particular white, cleaning products, but doing without classic opacifiers, in particular styrene / acrylates 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. Examples include documents DE 102015225003 A1 and DE 102015225005 A1, 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 generally 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 opacifying agents, 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.

Information on this is given in 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 develop foam according to the cited document.

Conditioning shampoos are disclosed in document WO 2007/104740 A1. These shampoos can be in the form of an emulsion which contains 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,

 • contain 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.

The preparation according to the invention is used to clean the hair and skin. The product forms include body cleansing products such as shower baths, bubble baths, liquid soaps, foaming facial cleansers, and others. Product forms for hair cleaning, for example hair shampoos, conditioning shampoos and others, are also included.

The present invention also relates to the use of a cosmetic cleaning preparation comprising

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 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, they also stabilize the emulsion formed. They stabilize the emulsion formed by interfacial films and by the formation of steric or electrical barriers, which prevents the coalescence of the emulsified particles.

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 - Mi _ip ophii / M), where M pophn for the molar mass of the lipophilic portion in the emulsifier and M for the Molar mass of the entire emulsifier is.

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.
