Description

Cosmetic product for make-up removal, skin care or hair care in the form of a towel or swab

The invention relates to cosmetic agents for Make-up removal, for skin care or hair care that the active ingredient in association with a flexible carrier contain and in which the active ingredient only after a sufficient mechanical pressure has been exerted on the carrier is released at the time of application.

Make-up removal wipes and tissues for skin care, for example in the form of an absorbent paper, on its surface or in its mass contains the cleaning agent are already known; with these products but if the active ingredient is in a free state and can change adversely over time or neighboring ' Affect objects, for example, dirty. ■

The invention has for its object to circumvent these disadvantages and cosmetic agents in the form of, for example, towels or To provide swabs for make-up removal or skin care that have a practically unlimited shelf life.

It has now been shown that cosmetic tissues and swabs are ideal for removing make-up, or for skin care let the hair care, for example hair dyeing, which do not have the disadvantages mentioned, by the cosmetic active ingredients enclosed in microcapsules and these inside the carrier or simply on it Ground the surface in a distributed manner.

The invention therefore relates to cosmetic compositions for removing make-up, for skin care or for hair care in form a cosmetic tissue or swab containing a

Cream, an emulsion, a powder base, a hair dye or similar products and is characterized in that the active ingredient used is enclosed in microcapsules and is connected to a rigid, flexible carrier and that the active ingredient is only released after being on the carrier at the time of application, a mechanical pressure was exerted sufficient to tear the shells of the microcapsules. Dje skin care products are means that the skin soften and / or regulate their moisture content, protect them from the sun's rays and / or the formation of wrinkles counteract.

The invention also relates to the method for producing the cosmetic wipes according to the invention and swabs. '

A swab is a cosmetic carrier that is voluminous, not just a surface

which can be made from a wide variety of materials.

The method of enclosing the cosmetic active ingredients in microcapsules does not form part of the invention, however this inclusion in microcapsules in a separate process step takes place and the microcapsules obtained are used as the starting product.

According to the invention, the cosmetic wipes and swabs are produced in such a way that the microcapsules which contain the cosmetic active ingredient are introduced into the carrier mass during the course of the production of the solid cosmetic carrier and this mixture is then immediately shaped _; the microcapsules remaining unchanged during this treatment or by spraying microcapsules in a liquid carrier onto the flexible, solid carrier previously covered with an adhesive.

According to a first procedure, the starting product is a paper pulp for - absorbent paper is used and in this pulp the previously prepared, in the following microcapsules designated as rait C. The production of the cosmetic wipes or swabs then takes place analogously to the production of conventional ' -d absorbent papers, tfobei however under Conditions are worked that on the one hand that in the Microcapsules C enclosed active ingredient and on the other hand the compounds forming the shell E of the microcapsules are adjusted. ·

Compounds are therefore used as the material for the covers E selected which, above all, have good mechanical strength and have heat resistance and a sufficient degree of elasticity.

According to another embodiment of the invention In the process, a synthetic polymer or copolymer is used as the carrier material instead of the absorbent paper used, either thermosetting or by polycondensation or polyaddition in the presence of a catalyst has been received. However, in the course of its manufacture, the following conditions must be met:

The monomers or used as starting material Prepolymers or starting products for the polyaddition or polycolidensation must be sufficiently fluid to allow easy introduction of the microcapsules C and thorough homogenization, wherein dip densities of the capsules 0 and the liquid phase if necessary must be coordinated;

the connection of the constituents that make up the envelopes E, mÜRRon oine good heat resistance U2id sufficient Have plasticity;

the casings E must be chemically resistant to the pure liquid Phnse.

The completion of the synthetic product that which contains microcapsules, takes place with the help of a heat treatment or a catalytic treatment under Observance of the above conditions, depending on the polymeric compound used, either films or Foils small, thick or a foam with any desired density can be obtained and wherein the microcapsules with the cosmetic active ingredient in the mass of the polymer are included.

The advantage of cosmetic swabs made in this way in the form of a foam "low density" is easy to see: The sealed in microcapsules

Make-up or care products are only released by a pressure exerted with the fingers or by being held, or by the pressure exerted when the item is placed on the desired area. A low-density cosmetic wipe can also be made from the same material. .

The films or foils containing the microcapsules, in which the cosmetic active ingredients for make-up removal and / or skin or hair care are enclosed, are advantageously embedded in tissues made of absorbent paper which are shaped into pouches; the films or foils in these pouches are either cut as one piece in the form of the pouch or in strips. It can be produced multi-purpose towels to DIE _s ge manner that the position of the foils are differently colored microcapsules with different contents, and therefore different properties accordingly.

According to another form of training, the cosmetic towel according to the invention on a make-up removal side and a skin care side. In this case contains the cloth made of absorbent paper has two small pouches separated by a thick film, one of which the make-up removal film and the other the skin care film records. ~

On the one hand, casings are sufficiently strong, above all heat-resistant, so as not to be attacked under the manufacturing conditions, but on the other hand the active ingredient enclosed in them can easily be released by mechanical pressure at the time of use.

is mainly used when the microcapsules are to be enclosed in a thin film and the addition is made in this case before the film is completely polymerized.

At the end of production, the microcapsules C are embedded in the carrier mass, the carrier being an absorbent capable paper, a thin film or a foam made of synthetic material. Thereupon the carrier mass is with embedded microcapsules shaped or cut to the cosmetic wipes or swabs according to the invention.

In general, after the introduction of the microcapsules into the carrier mass in the form of a liquid or a The best possible homogenization of the suspension is achieved through adequate mixing, stirring, shaking or blowing in of a gas achieved. The density of the liquid or suspension mass is the density of the Microcapsules made up by adding one of the components of the carrier or a suitable inert substance; possibly Premixes are also made that combine the microcapsules with some or some of the carrier mass Contain ingredients. The microcapsules can also be selected so that their density matches that of the liquid-K speed or the suspension when introduced into this corresponds.

In addition, the shells of the microcapsules selected so that they easily push and a low temperature of 50 - 6O ⁰ C withstand and in some cases considerably higher temperatures, if the manufacturing process of the carrier requires it.
