Description

Cosmetic with inorganic fillers and active ingredients

The invention relates to cosmetic compositions containing certain inorganic fillers and thus exhibit special effects in terms of UV-behavior, IR behavior, color cosmetic and skin feel.

To improve the UV protection of cosmetics will for some time include inorganic oxides such as Ti0 2, ZnO, used Si0 2 or Zr0 second It is also known that so-called glass flakes, such as Si0 2 flakes or Al 2 θ 3 flakes in the initial state or, preferably, coated with metals or coloring metal oxides in pigment mixtures or cosmetic formulations may be used (DE 198 23 866, EP 1013 725). Such flakes are produced, for example as platelet-shaped transparent matrix on an endless belt and have a thickness of 0.1-5 microns and a length or width of 1-250 microns.

The invention has the object of finding novel cosmetic formulations with specific color properties and light radiation absorption-influenced to develop properties together with improved skin feel.

According to the invention the new cosmetic with inorganic fillers and active substances containing milled, optically clear glass particles having an average particle size of 0.01 to 100 microns in an amount from 0.1 to 55% by weight, wherein the glass particles from a molten and subsequently solidified glass are formed and are selected from the group consisting of soda-lime glasses, borosilicate glasses, Alumosilicatgläser high refractive index (heavy) Bleialkalisilicatgläser and mixtures thereof, and it contains further cosmetic carriers, auxiliaries, active ingredients and mixtures thereof up to 100% by weight, based in each case on the total weight the cosmetic.

By "glass" means an inorganic material mixture, which is cooled from the molten state without crystallization, and has adopted a solidified state.

The usable according to the invention, the silicate glasses already mentioned, such as soda-lime glass, borosilicate catglas, aluminosilicate glass of high refractive index include Bleialkalisicatgläser (refractive index n = 1.5-1.65, also known as "heavy" glasses hereinafter), preferably soda lime glass. Such glasses can be melted from sand, lime, alumina, boron compounds, potash, soda, etc., and in a molded state is allowed to solidify.

Under soda-lime glasses can be understood from the Si0 2 (eg 71-75%), Na 2 0 (eg 12-16%), CaO (eg 10-15%) and the rest consist of 100% melting aids and, optionally, coloring matters wherein a portion of Na by K and a part of Ca may be replaced by Mg.

Under borosilicate glasses which, in of Si0 2 (example 70-80%), B 2 0 3 (eg 7-13%), Na 2 0 / K 2 0 (eg, 4-8%), A1 2 0 3 ( for example, 2-7%) and the rest consist of 100% melting aids and, optionally, colorants.

Under Alumosilicatgläser such glasses are understood where Si lattice sites are occupied by the glass network by aluminum. Highly refractive Bleialkalisicatgläser are glasses, which in addition to Si0 2, Na 2 0 / K 2 0 and CaO lead oxide high levels, eg 10-40%. The glasses of the invention do not contain P 2 0. 5

By adding various metal compounds glasses can take different colors. For example, Cu Cr 6+ Mn 3+ + leads to a weak blue, Cr 3+ to green to yellow to violet, Fe 3+ to yellow-brown, Fe + (to blue-green, Co 2+ to intense blue or pink in borate glasses), Co 3+ to green, Ni 2+ mass colored, depending on the glass matrix to brown-yellow, yellow, green, blue to violet, V 3+ to green or brown, etc. this gives or mass tinted glasses. Intense yellow, orange or red colors are obtained by precipitation of noble metal colloids, selenium, cadmium sulfide and Cadmiumseienid during cooling of the melt or by subsequent heat treatment. These glasses are also referred to as "start-up glasses", such as the famous gold ruby ​​glasses with gold precipitates in the glass matrix. Cosmetics containing such by mass or surface-colored glasses are a particular embodiment of the invention.

In order to obtain certain insulation against sunlight, it is known to evaporate thin layers of silver, tin, gold and / or copper on the glass surface on the outside of glasses. It is also known, for example, gray or window glasses bronze to drown out the purpose of brightness attenuation, or specifically to color yellow. They can also make opaque to UV radiation and short-wavelength blue, similar to glasses for sunglasses, where both effects can occur in combination.

Both simple by mass or surface-colored glasses and other equipped with special features glasses, such as surface-tinted -bzw. -bedampfte glasses, glass ceramics, IR-absorbing glasses, UV absorbing glasses, phototrophic glasses and mixtures thereof, can be set once according to the invention.

The glasses are previously subjected to a grinding process, for example in ball mills or roller mills, thereby achieving particle sizes of the glass powder of about 0.01-100 microns. Optionally, the glasses may be pretreated by a previous temperature treatment, followed by quenching prior to milling, for example by a temperature drop of about 800 "C to 50" C within 2 seconds.

Particularly preferred particle sizes of the glass powder having the different properties are between 0.1 .mu.m and 90 .mu.m, in particular between 0.1 and 10 microns, especially between 0.8 and 2 microns.

A preferred proportion of the glass particles in the inventive cosmetic is in the range from 0.1 to 45% by weight, in particular 1 to 20% by weight, particularly preferably 0.1 to 12% by weight, based in each case on the total weight of the Kos etikums.

By using the glass particles are obtained generally in addition to the coloring of the cosmetic significantly improved texture of the product and a better skin feeling. A cosmetic with glass particles having particle sizes below about 15 microns can be particularly soft spread on the skin. The added UV glasses and photochromic lenses can moreover, a significant reduction of organic filter recognize at the same sun protection factor, so that the risk of potential skin irritations in particular with high SPFs by organic filter substances can be significantly suppressed. IR glasses reduce the influence of IR-radiation on the skin. All lenses show light scattering effects that can enhance the special effects yet.

Microscopically, the milled particles have an irregular polyhedral shape with approximately the same length, width and height so that the glass particles are no glass flakes are not formed and scaly.

Preferred optically clear glass particles are dyed continuously by metal compounds in the glass matrix.

By "optically clear" glass particles are to be understood according to the invention, which is not turbid and incident light partially reflected, partially absorbed and partially transmit.

In another embodiment of the invention, a part of the surface of the glass particles can for example be tint color by metal compounds at least, by an appropriate post-treatment. The color tone can be formed advantageously in the form of tarnish by a cooling or heat treatment regime during or after the cooling phase.

In a further embodiment of the invention, the optically clear glass particles milled optical glasses in the form of crown glasses, flint glasses or mixtures thereof. Optical glasses are high quality glasses with high freedom from streaks, optical homogeneity of the refractive index that is constant within a melt, the smallest possible void content, low absorption in spectral regions defined and low birefringence. The basis for these glasses are soda lime silicate glasses (crown glasses), lead-alkali silicate glasses (flint glass) as well as lanthanum, B 2 0 3, BaO, A1 2 0 3, ZnO and fluorides for specific purposes molten glasses. These optical glasses can also be colored by metallic transition group elements such as Cu, Ti, V, Cr, etc. Such optical glasses are for example the glass or the glass D8010 S-8061 of SCHOTT, Germany.

In a further embodiment of the invention, the optically clear glass particles milled photoptrophe or photo- chrome glasses, wherein the terms are used interchangeably phototroph and photo chrome are.

In these glasses, the transmittance in the visible spectral range is reduced by irradiation with UV light. The glasses are dark. After completion of exposure, she goes after a short time back to its initial value. In this way, the transmission of visible light can be lowered to 20%, wherein the intensity of the light effect is proportional to the strength of the tint. (Halo gen = Cl, Br) or metal oxides are catgläsern the borosilicate here silver salts and metal halides added and during and after the melting process is carried out by a defined temperature control precipitation of silver halides, glassy and / - or crystalline components that cause the photochromic , Chemically is this metal excretion based on a redox process, in which the silver ions are reduced to metallic silver. This stained glass dark. Since the process is reversible, the silver atoms can re-emit one electron and change back into the transparent silver.

The described process occurs in phototrophic finely ground glass powder and within a cosmetic composition. Corresponding compositions may be all cosmetic sunscreen preparations for skin and hair as well as for decorative cosmetics such as make-up, foundations, lipsticks, etc.

The phototrophic glasses may use it as a UV filter function, thereby existing UV filter systems can be supplemented or replaced entirely. The UV filter action of the phototrophic glasses may be dependent on the intensity of the incident light, and would offer the most protection when the sun is shining most intensely.

Can be used for the invention photochromic glasses are, for example PhotoSolar ® Super Gray (code D1426), photo-sol ® Super Braun (D6220), PhotoSolar ® Super Brown (D6526), PhotoSolar ® Super (D6726), PhotoSolar ® Gray (D1125), HC PhotoSolar ® dark brown (D6625) from SCHOTT, Landshut, Germany or corresponding glasses from other manufacturers.

Another preferred glassy product are optically clear glass ceramics which can be transparent or non-transparent in the visible range. transparent or nearly transparent glass ceramics are preferred. In glass-ceramics, the cooling of the glass contained in the melting state is controlled so that submicroscopically fine crystallites are formed in suitable glass systems that control as a nucleating agent, the crystallization of the glass in certain extent. This can cause different crystal phases and as the end product materials with extremely low expansion over a wide temperature range or those with mica-like crystals. Such glass-ceramics are between glasses and ceramics and have the crystal formation in a ground state special refractive properties. Special color effects can be obtained from so-called polychromatic glass ceramics. Here, the crystallization is prepared by UV radiation and set in motion by subsequent heating. This requires the presence of a few percent alkali metal fluoride, zinc and aluminum, and small amounts of silver compounds and cerium oxide in the Silicatglasmatrix. By UV irradiation, metal colloidal particles that act as nuclei for the devitrification and transform the system with further annealing in a yellow to amber colored glass ceramic form. In the presence of other halogens (bromine, chlorine), any other color tones are generated due to various crystallites by repeated ultraviolet irradiation and heating, which can impart special light scattering and color effects of the cosmetic products.

In a further embodiment,

- the glass particles from optical glasses

- the particles of glass-ceramics

- the UV and IR filter glass particles

- the Photochro s glass particles

- Spiegelglasteilchen

- mixtures thereof, respectively silanized at the surface thereof, thus resulting in different hydrophobic / hydrophilic interactions with the water phase or the oil phase. Example, an improved hydrophilic property of the particles can be achieved through the silanization of the glass surface, whereby an improved incorporation of the particles is possible in the cosmetic formulation and improved stability of the emulsion. Silanizing as such is known and can be performed in liquid or vapor phase, for example by treatment with a suitable silane as a tetraalkylsilane.

The inventive additives of various ground glass powder UVA and UVB absorption and / or reflection can be selectively affected by cosmetic formulations depending on the type and amount of the glass powder. Also, the IR absorption and reflection may be influenced in certain extent. In addition, the glasses may be pigmented properties. A particularly preferred cosmetic composition may comprise such glass powder, which can change their color and / or absorption properties under certain conditions, such as UV irradiation, or those glasses which are multiply coated on the surface with materials having different refractive indices, thereby interference, and / or to achieve reflection.

A special effect can be achieved by a different light scattering of glass particles, particularly when mixtures of different glass particles are present. Another embodiment of the invention is to employ glass particles with IR-absorbing properties in a cosmetic formulation. Recently, it is argued that skin-damaging effect not only of UV rays but also and above all of IR radiation emanates. IR radiation is to be involved in the development of skin cancer. Since the reaching the earth's solar radiation consists of about 46% of IR radiation and do not affect sunscreen products wärmeabwehrend, each sunbather an increased infrared effect is particularly exposed. This is particularly encouraged by the practice that when using a sunscreen of staying in fully einstrahlender sun can be extended very long, depending on the height of the sun protection factor.

By an inventive cosmetic containing glass particles from IR filter glasses, radiation can be effectively absorbed from the IR region of the spectrum with wavelengths> 780 nm. This skin aging and skin cancer risk is significantly reduced.

Another embodiment of the invention is to employ glass particles having UV-absorbing properties in a cosmetic formulation. Such glasses include, for example blue filter glasses and clear filter glasses. A blue filter glass for example, is a dark purple or deep dark purple or blue colored silicate glass such as M-UG 6, M UG 6 plus, M-2 or UG UVISOL 95 SCHOTT, Germany. In these glasses, the spectral transmittance is in a nearly Gauß'sehen distribution curve (curve error) in the range from about 300 nm to about 420 nm between 0 and 80%.
