foam preparation

The invention relates to a foam preparation, in particular a

Rasierschaumzubereitung.

Shaving foam, but also mousse, Tönungsschaum or other foams are known in a variety of dosage forms. First, shaving cream is often made by using soap, most often, special shaving soap using a shaving brush and water by frothing.

This is the oldest form of shaving cream needed to achieve a gentle wet shave.

Especially in this oldest form of Rasierschaumerzeugung it depends very much on the skill of each user. Just when too much water is used, it comes to low-viscosity foams, which can serve insufficiently as a lubricant during shaving.

The provision of a shaving brush is necessary. Although shaving soaps are now used in paste form, this is only a small step forward.

In addition, the use of foams, especially shaving cream or shaving gel from the can is widespread.

However, these cans are filled with propellant, which is why they are usually made of metal and must have a relatively large volume.

But just these cans are a problem during air travel and may often not be taken.

The entrainment of shaving brush and shaving soap or shaving paste, however, is expensive and is therefore rarely practiced.

Both variants can also be difficult to portion, so that a

Disposable is usually excluded.

In addition, in known shaving foams, a considerable amount of waste is generated by propellant cans.

The object of the invention is therefore to propose a foam preparation, in particular a shaving foam, which can be easily transported without violating any safety regulations and also allows a portioning in individual portions, and contributes to waste prevention.

This object is erfmdungs solved according to that two substances

are provided, which are brought into contact with each other for producing the foam.

By bringing the foam from the foam preparation is made. It is very advantageous in this case if the two substances react chemically or physically with one another and thus a foaming takes place, whereby the foaming can also be an indirect consequence of the chemical or physical reaction.

By the reaction of the two substances with each other, the foaming is initiated, for example, the foam can be generated directly by a reaction of the two substances. But it is also conceivable that a part of

Ingredients are released or dissolved by bringing together and so on

Foaming is initiated.

According to the invention, it has proved to be extremely advantageous if the second

Substance is water.

Water is always available when shaving and is therefore easy to handle.

Another very advantageous embodiment of the invention is when at least part of a substance is neutral, basic and / or acidic.

By a neutral, basic and / or acidic interpretation of the substances or parts of the substances, not only a better reaction of the substances

each other and thus a better foaming can be achieved, but it is also an adaptation to the skin of the user conceivable. In order to avoid skin irritation, the shaving cream should end up with a pH close to 7, whereby a slightly basic design is conceivable.

Another very advantageous development of the invention is also present if at least one of the substances surfactant components, soap components,

Stabilizers and / or care substances or the like. This optimizes the properties of the foam, in particular of the shaving foam and thus its usability. Already by using a surfactant and excipients, a stable and very good shaving foam can be produced.

Another very advantageous embodiment of the invention is when a

Foam, in particular a shaving foam from the preparation is prepared by mixing the two substances.

Thus, the foam, as soon as it is needed, can be easily manufactured.

It is also very advantageous according to the invention if the substances are packaged in separate containers or chambers of containers.

This prevents premature mixing of the substances.

It has proven to be very advantageous if at least one of the substances is packaged in sachets or the like.

By packaging in sachets, especially in sachets and a one-time application can be realized. Above all, however, such small amounts of non-pressurized substances can also be taken without problems in air traffic.

Another very advantageous embodiment of the invention is also present if at least one of the substances is provided as a liquid, gel, powder, tablet or the like.

This ensures a very good workability and portability. It has also proved to be extremely advantageous according to the invention if a so-called tablet explosive is provided in the case of a substance in solid form.

By a so-called tablet explosive a solid component is torn open almost abruptly, for example by adding the other component or by adding water, whereby a very good miscibility is ensured.

Another very advantageous embodiment is also that in at least one component, one or more of the following ingredients are included:

- Sodium myristoyl glutamate (sodium myristoyl glutamate)

- Sodium bicarbonate

- talc

- citric acid

- maltodextrin

- Xanthan.

With these ingredients can form a stable foam, with the help of a razor can slide very well over the skin.

Likewise, it is very advantageous according to the invention if one or more of the following care substances are contained in at least one of the components:

- aloe vera

- Licorice extract

- talc.

These ingredients ensure optimal care of the skin and soften the shaved hair. This results in a very good, even and smooth shave. In the following the invention will be illustrated with reference to several embodiments.

The first embodiment relates to a Rasierschaumzubereitung, which is liquid or gel-like. One part of the shaving cream preparation contains a surfactant mixture, wherein a gel is used as carrier material. This part can be neutral, basic and / or acidic. In addition is

Sodium bicarbonate solution or sodium bicarbonate powder or

Sodium bicarbonate containing, which is used as foaming agent for foaming the

Preparation for shaving cream is provided. The sodium bicarbonate is activated by an acid component, for example by citric acid and so the

Foaming started. Further, as the foaming agent, sodium lauryl sulfate, sodium myristoyl glutamate, or the like may be provided, especially, if the surfactant mixture does not already exhibit a sufficient foaming property. It is also conceivable to replace the sodium myristoyl glutamate or another surfactant with another substance, which may also be a surfactant, for example sodium lauryl sulfate. Instead of the surfactant, similarly acting compositions may be provided as foaming agents.

Instead of the surfactant mixture, a soap component or the like may also be used.

It is also conceivable that this part of the Rasierschaumzubereitung is present as a solid and is thereby formed as a powder, granules, tablets or the like.

If a solid is chosen, it can still have a so-called

Contain tablet explosive, which breaks up on contact with the second part or with water existing larger chunks of solids and so a uniform

Mixing of the two parts allows.

As a second part, a liquid or aqueous component is provided, which may also be thickened to a gel. This part is also neutral, sour and / or basic. The carrier material may also be a gel, in particular an aloe vera gel. This part contains citric acid, which activates the propellant sodium bicarbonate. An additional foaming agent like

Sodium lauryl sulfate or a surfactant may be provided.

Preservatives may be provided in both parts, this, if any, being necessary only in the second component.

Both parts may be added to adjust the viscosity or thickening of hydroxyethyl cellulose or another suitable substance such as, for example, algae-based agar, xanthan or the like. Other additives, in particular for stabilizing the shaving foam to be formed and / or skin care are conceivable.

Here, additives such as aloe extract, licorice extract or the like are conceivable.

If the two parts or components are brought together in a predetermined ratio, the sodium bicarbonate and the citric acid react in a first step to sodium citrate and carbonic acid. The carbonic acid decomposes into carbon dioxide and water.

By the resulting carbon dioxide, the surfactant or an added

Foaming agent, such as sodium lauryl sulfate, foamed.

By foaming, all ingredients are evenly distributed throughout the foam. The ingredients have a very good cleaning and care effect, but also act as a lubricant to allow easier sliding of a wet shaver on the skin and avoid skin irritation.

To initiate the foaming and thus the production of the shaving cream, the two parts of the shaving cream preparation are brought together and for Example mixed with your finger. Already when mixing the reaction starts immediately. The foam is generated.

The two preparation parts can be packed, for example, in a two-chambered portion bag, for example in a sachet. This one is added

Use torn and deflated.

It is also conceivable that separate bags are provided for each part of the preparation.

Other forms of administration, for example by dispensers or the like are conceivable. It is also conceivable that the two preparation parts are packaged in tubes, cups or the like.

However, the portioning has proven to be particularly advantageous. Especially with individual portions, these can be presented, for example, in hotels. But also a transport in airplanes is unproblematic. Due to the small amount of content, it is also possible to take them with you in your hand luggage.

Another embodiment is based on a dry tablet containing the shaving cream composition. This is wetted with water, which on the one hand dissolves the tablet and on the other hand starts the foaming process.

It is also conceivable in this connection that a granulate, powder or other solid is provided which contains or consists of the shaving foam composition.

It is particularly advisable in this context, if a so-called tablet explosive is provided, which accelerates the dissolution process of the tablet or the solid. Dry products, especially in tablet form are completely unproblematic transportable and also no problem substance in aviation.

For example, these dry tablets may be individually sealed to protect them from moisture and dirt. Another single or collective packaging is conceivable.

Each individual tablet is adjusted so that it produces a foam portion that is sufficient for one application.

Also possible according to another embodiment powdered or granular dosage forms, which must be wetted with water, as already indicated above.

In addition, liquid dosage forms for the two preparation parts are conceivable.

It is also conceivable that a preparation part is dry and a second liquid or pasty.

But there are also other applications conceivable. Thus, it is also possible, for example, to design so-called mousse or tint foams according to the present invention and thus to problematic with

To dispense propellant-filled cans. A particularly well-functioning composition contains sodium myristoyl glutamate, sodium bicarbonate, talc, citric acid, xanthan, maltodextrin,

Aloe extract and licorice extract.

This composition is thickened and dried by the xanthan and is therefore present as a powder.

By moistening the powder with water it foams up and forms a stable and nourishing shaving cream. The sodium myristoyl glutamate is the foam base, which already has very good sliding properties. This is through the

Sodium bicarbonate foamed in conjunction with citric acid. Aloe and

Licorice root extract are nourishing additives. In addition, talcum may be added as a dyeing or lubricating agent.

This composition may be stored moisture protected in sachets or in another container, for example a doser.

The composition does not contain any harmful substances and is completely naturally biodegradable.

The majority of the composition consists of approximately equal shares of sodium myristoyl glutamate and sodium bicarbonate of almost 40% each. Talc is about 10% contained.

The remainder is divided among the remaining substances, with citric acid accounting for the largest proportion, followed by xanthan thickener.
