Description

"Cosmetic preparations with low textile adhesion"

The invention relates to cosmetic compositions for personal care, which contain a special oil mixture, and which are particularly suitable for the preparation as an antiperspirant.

Washing, cleansing and caring for the human body is an important basic need, and cosmetic manufacturers are always trying to meet the ever-changing and evolving needs of consumers by providing novel and / or improved products.

Cosmetic care products often comprise a higher proportion of one or more oils and, when in contact with textiles, can lead to the formation of stains on the textiles. In particular in combination with other content and active ingredients contained in the care products, such as, for example, dyes and / or perspiration-inhibiting (aluminum) salts, the textile stains can be particularly stubborn and difficult to wash out.

Make-up spots in the area of the collar or neckline and / or white residue in the underarm area of textiles are typical examples of hard-to-wash textile stains. White and / or yellow patches in the underarm area of textiles can be caused by the regular application of antiperspirants. These stains are probably caused by the formation of initially insoluble aluminum compounds on and within the textile fiber. The yellowing usually occurs with a time delay and is at least partially caused by oxidation of unsaturated fatty acids present as insoluble aluminum salts. In addition, other different factors can interact in unexpected ways and, for example, depending on the choice of perfume oil, the detergent and / or depending on the individual amount and composition of sweat promote the formation of pronounced yellow spots on textiles.

The interaction of detergents and antiperspirant active ingredients produces insoluble compounds that can be absorbed by a textile. These insoluble compounds form white, hard residues, which usually show up after several soiling and washing cycles on the textile. These white residues are insoluble in water and can not be removed by a standard washing procedure. They are particularly noticeable on light or dark colored textiles. The clever choice of additives leads to a significantly lower or delay the formation of these insoluble deposits.

As suitable additives in antiperspirants, high refractive index oils have been described which cover the white residues. However, oils with a high refractive index tend to accumulate in particular on cotton and form dark greasy or oily stains, which may adversely affect, among other things, the feel of the textiles in the soiled area. The use of predominantly volatile oils, such as cyclopentasiloxanes, in antiperspirants, in turn, largely prevented the formation of wet, dark oil spots on the textiles, but did not prevent the formation of white residues caused by (aluminum) salt residues.

Another disadvantage of using only volatile oils in cosmetic compositions is that volatile oils often do not have a satisfactory skin care effect and that, especially in high concentrations, they can result in aerosol applications to a dusty, low-focussing spray jet.

There is therefore still a need for cosmetic products for personal care, which leave less or no stains on textiles, or which can be easily and thoroughly removed by washing.

It is an object of the present invention to provide cosmetic personal care products which have a high content of skin-care oils which ensure good adhesion to the skin or good penetration into the skin. At the same time, the cosmetic products should have a low adhesion to textiles and, if possible, should not lead to undesirable staining in interaction with other constituents of the formulation.

Another aim was to formulate in particular oil-based, well-tolerated antiperspirants so that even after regular use they have less to no dark oil spots and / or white to yellow spots.

It has now surprisingly been found that the above-mentioned objects are achieved to a great extent by means of cosmetic compositions for personal care containing a special mixture of different oils.

The oil blends are readily incorporated into a variety of cosmetic care compositions and may even serve as the predominant basis for cosmetic compositions. They show an excellent skin care effect and a very good washability from textiles, especially cotton. In addition, when used in antiperspirants, the oil blends have an excellent effect of covering / reducing / preventing white aluminum salt residues.

A first subject of the invention is therefore a cosmetic composition for personal care, which contains (in each case based on the total weight of the composition) an oil mixture in a total amount of 40 to 99 wt .-%, wherein the oil mixture

b) at least one cyclic polydimethylsiloxane, and

c) at least one linear polydimethylsiloxane having a kinematic viscosity of less than 20 cSt at 25 ° C contains.

According to the invention, suitable cosmetic compositions for personal care are preferably skin treatment compositions which have a high content of hydrophobic active ingredients (oils), for example skin creams, make-ups, lipsticks, other decorative cosmetics such as eyeshadows, scrubs, skin lotions, deodorants, antiperspirants, hair oils, styling agents and / or pomades.

An addition of low-viscosity linear polydimethylsiloxanes to the oil mixtures gives the oil mixtures and the compositions according to the invention particularly advantageous performance properties. These include, in particular, the rheological properties of the oil mixtures or of the cosmetic compositions according to the invention, such as the spreading behavior. In addition, addition of linear polydimethylsiloxanes having a kinematic viscosity of less than 20 cSt at 25 ° C promotes to the oil blends both the good washability of oil stains which can be caused by high oil refractive index ester oils and washability white stains on textiles caused by the deposition of aluminum salts from antiperspirants.

The encapsulation can be carried out by known methods. Corresponding methods are for. Disclosed in K. Master, Spray Drying Handbook, 3rd Ed., John Wiley, 1979. In a particularly preferred encapsulation process, a water-based mixture comprising about 20-50% by weight of the polymeric encapsulating material, about 0, is prepared. 1 to 2.0% by weight of an emulsifier, about 5 to 20% by weight of the perfume oil to be encapsulated and / or the skin-cooling active ingredient to be encapsulated and about 40 to 60% by weight of water. This mixture is homogenized and then spray-dried. The active ingredient-loaded capsules are thus obtained as a fine powder having a particle diameter of 1 to 150 μm, preferably 20 to 80 μm, particularly preferably 5 to 50 μm.

In another Herste II process, the microencapsulation is carried out by coacervation, wherein the carrier is preferably formed from gelatin.

The capsule material, consisting of water-soluble polymers and a low content of emulsifiers, allows a reversible "re-encapsulation" of the encapsulated perfume oils and skin-cooling agents. The re-encapsulation occurs in situ during the drying of the Skin following a perspiration period. Thus, various, successive activations occur on the skin, without the user having to make a further application of the agent according to the invention.
