Description

For connecting or embedding the hollow microbeads, all known so-called ones are suitable "Ointment bases", in particular vegetable and animal fats and oils, stearin, wool fat, fatty alcohols, lanolin, waxes, mineral oils, petrolatum ^ Gelatin, glycerin, lower alcohols, solvents, etc.

According to the invention, the cream or the like consists of 5 to 96% by volume, preferably 18 to 72%, made of hollow microbeads.

The cream or the like according to the invention has a density of 0.05 to 0.91, preferably from 0.16 to 0.48, and has a foam-like consistency.

It is particularly easy to apply and evenly to the skin at all temperatures distribute.

The foam-like consistency of the cream according to the invention is achieved by pressure, heat, moving air, as well as not destroyed by moving water.

The cream or dgL is breathable and does not or does not interfere with skin breathing in layers under 1 mm barely. It is therefore with appropriate active ingredients as a cream for face masks and as an ointment particularly suitable for burn injuries

As a result of the air encapsulated in the hollow microbeads, which cannot escape even under pressure, the cream according to the invention has excellent cold and heat insulating properties. she is therefore be used as a protective cream against cold water, as used by swimmers and divers especially suitable

The high-polymer hollow microbeads made of polyvinylidene chloride copolymer are preferably used and are non-flammable. In connection with incombustible liquid or pasty substances, such as. B. Chlorine paraffin, they are particularly suitable as protective creams

in the event of fire disasters, when working on blast furnaces, etc.

Another one? The advantage of the invention is that

that the micro hollow pearls as such are physiologically absolutely harmless to the human

ao or animal body and the active substances behave.

Claim: punch, such as B. the propellant, the emulsifiers and the foam stabilizers with many medicinal Crerae, ointment, paste with medicinal and / see and / or cosmetic active ingredients un-K or cosmetic active substances that are harmful to cleansing 5, or react with them and their effects reduce or undesirably increase the and / or protective properties.
⁴ characterized in that the cream A disadvantage is also that in particular is liquid, pasty or wax-like, and minor propellants and emulsifiers physiologically not instens partially consists of hollow microbeads, 4e are different and particularly uncomfortable on the ren thin shell made of a thermoplastic io affect mucous membranes and often cause allergies. Plastic is formed, and that these micro-hollow A major disadvantage of every cream or the like. Bead have different diameters ^ it says that their viscosity is to a large extent of ·· ■ "" ■ 'the temperature of the cream, the air and that of the Body depends, which makes a uniform distribution 15 difficult or impossible The viscosities of all creams or the like, especially those based on a greasy cream / ointment base relatively low density, are in the use range of -25 ° C (UV protection cream for winter sports) ao to + 55 ° C (UV protection cream for beach holidays) very different and range from liquid to waxy. The invention has the task of eliminating these disadvantages and creating a cream a5 which has a low density and which is wide Temperature range approximately the original The invention relates to a cream that retains low viscosity. The foam-like consistency Dense, in particular a cream, ointment, paste or the like. No or hardly any moisture to the atmosphere with medicinal and / or cosmetic active substances and which are unStanzen in this foam-like state, or cleansing and / or protective egg pressure and / or heat does not collapse, itself properties. Can be easily and evenly distributed, insulating and A cream or the like, as it has, for example, breathable properties, physiologically Cleaning and care of teeth and gums, is indifferent and the active substances against each other as well as behaves to protect the skin and to heal excessively neutral. It is also part of the task Wounds, as well as for treating allergies, also 35 of the invention, expensive active ingredients and expensive SaI-AIs Face masks to save for removing body skin bases. th and calluses, as well as is used for shaving, the solution to this problem is according to the invention is usually a liquid at room temperature in the characteristics of the mark of the ancestor has solid or pasty thixotropic substance with egg saying and reads: cream, ointment, paste with medizitier high density. From a physical point of view, there are disparate and / or cosmetic active substances persions, emulsions, pastes, oils, gels, solutions with cleaning and / or protective properties, or mixtures of the above. Mostly contain characterized by the fact that the cream is liquid, pasty it is for the respective application areas in addition to or similar to wax, and at least partially off whose medical and / or cosmetic active substance is made of hollow microbeads, the thin shell of which is punched from ice. 45 nem thermoplastisdien plastic is formed, and It is known to foam a cream or the like. that these hollow microbeads have different durdimes if you use a propellant that own through his water. Expansion (evaporation) the cream when leaving In a particularly preferred manner, the micro- the pressure vessel foams. hollow pearls from the liquid or pasty substance It is also known to completely surround a cream or the like together 50, that is to say embedded in it. According to the With emulsifiers and foam stabilizers media invention, the hollow microbeads have a smooth foaming using a high-speed stirrer. Surface and always come in different It is also known a cream or the like. Direct size, that is, with different diameters for sale to lather the skin (shaving foam). turn. In a preferred manner, the closed In all cases, the fringed cream or the like is extremely unstable and sensitive. The foam collapses vinylidene chloride copolymer.
after a short time due to the release of moisture to the micro-hollow beads are also understood here as micro-skin and / or the atmosphere or, spontaneously, in the case of hollow spheres, their thin shell from a pressure. The foam is particularly unstable when there is heat made of thermoplastic material, and the inside and moving air and when moving water. The 60 are hollow, or contain a gas in their core, the desired iso- this is preferably air from a foamed cream or the like. The protective, healing, active substance-containing microbeads that are required for use have, as already mentioned, the feeding effect, therefore, only imperfectly have different diameters, namely from ranges. In addition, the cream, especially if 0.005 to 0.65 mm, preferably from 0.01 to it is applied in a thicker layer, is not at-65 0.09 mm. active and prevents skin breathing.
