Description

The present invention relates to an aerosol preparation.

Countless attempts to create an aerosol emulsion to produce a continuous, uninterrupted film or coating, whether for decorative or protective purposes, colored or colorless, in the form of various types of finish products, lubricants, etc., in which water forms the continuous or external phase , have so far been unsuccessful. With today's knowledge, it is known that oil-in-water emulsions are unsuitable for such purposes, since they result in foaming, which can basically be of two types: the conventional foams, such as those known for producing shaving cream

However, such foams are recognized- doubts eliminated which, with the delivery of an atomized fluid, are physically very different from a consistent, non-active ingredient which is found in the known organic solvents.

In this sense, no emulsions of phatic carbon and chlorinated solvents have so far been found which, by spraying, borrowed the production and can also be dispersed in water at low concentrations of nes unbroken coating on a special 1-2%, and soluble with a higher concentration-concentrating surface, especially not with water ions, in such a way that they contain highly viscous active ingredients or active ingredients with a 10% solution. 20 kös, almost like a gel.

This active ingredient or the like, other solvents than water as a carrier.

It is also - and most important - in the active part of the active solvent mixture that an active ingredient phase, a so-called dispersing or distributing agent, can be added. Therefore, a single-phase system was actually used, which took refuge in the two phases, but in a different solution or in a solution, in which the active amounts are solvable.

If the preparation is to be used, it must immediately be shaken, for example, by the high risk of accident in the case of exceptionally telbar before it is dispensed, and then in the essentially flammable aerosol color due to the fact that it is borrowed then be sprayed, leaving the solvent kept. The majority of the spray available on the market is temporarily a mixture. The used and available solvents then have sprayed material on the application area, which has low threshold values in this regard, which are formed by the continuous film, which is not dangerous holes, pores or geometrical structures due to the atomization process of the selected aerosol become interrupted. Furthermore, most of these solutions result in a coating of the desired thickness and completely tel undesirable ecological consequences by continuously developing one. As mentioned, the further depletion of fossil fuel sources has proven to be very successful for the filmic gene, not to mention its inefficiency in the application of water-based paints and for light from the continuously increasing costs of this fuel other film-producing products, of which fabrics. In addition, these solvents continually produce no previously unpleasant and even offensive odors for the formation of a film by sputtering. was known. Although the components of the preparation

To create a water-based aerosol preparation, which in lauric acid, is 3 to 4 wt .-% in the maximum and

pH of a 1% dispersion is between 8 and 9. This commercially available compound is said to be soluble in alcohols, glycols, ketones, esters, aromatic and aliphatic carbon and chlorinated solvents, although it is also found in water at low concentrations of 1 to 2% is dispersible. It is said to become soluble at higher concentrations and to become quite viscous, almost like a gel, with a 10% solution.

It can be seen that an addition of approximately 0.5% by weight of cocodiethanolamide of the system or of the preparation reacts with the water phase and the active substance phase, and what is generally referred to as an unstable emulsion, in other words produces the Phases tend to separate. However, the preparation can be brought into a relatively stable position by shaking. After atomization, the phases separate and disintegrate into their starting components, whereby the active ingredient does not form a continuous film, but one that is highly uneven and interrupted, typical results that are shown today when water-based solvents are used in aerosol form.

If the proportion of coco diethanol amide is increased in the range immediately above 0.5 to about 2.5% by weight, a stable emulsion results, the coco diethanol amide acting in the expected manner as an emulsifying agent, such as in a water / oil emulsion. Therefore, after spraying such a preparation with the specified amount of coco diethanolamide, a discontinuous, broken film is formed, despite the fact that the emulsion is stable. In its general normal state, the emulsion appears as a homogeneous, pasty substance of a stable nature. The foregoing therefore underlines that cocodiethanolamide, in the specified proportions, used with the active ingredients of the preparation according to the present invention, serves in its characteristic function as an emulsifying agent and that with the the resulting atomization product cannot produce a continuous film.

However, if the amount of cocodiethanolamide added is increased above the value of 2.5% by weight and is in the range from 2.5 to 10% by weight, the system loses its stability, so that the components are immediately separated which, when looked at briefly, resembles the appearance of the unstable emulsion containing 0.5% by weight of the above-described agent in question. Regardless of any visual similarity between the separation phases of the unstable emulsion and the preparation, which has over 2.5 wt .-% coco diethanolamide, the generally corresponding phases are very different both chemically and physically.

It appears that the preparation with the larger amount of coco diethanolamide has become a dispersion. However, this is atypical for the previously known technology, which, as mentioned, knows the immiscibility of the two sharply defined phases. Without any further intentions of limitation, the preparation is subsequently accepted as a dispersion. This is only done to make the designs easier. The agitation before spraying causes only a momentary mixing, so that after spraying the dispersion properties are decisive, in contrast to the emulsion properties which would be decisive if 2.5% by weight or less coco diethanolamide were present. Applying a dispersion creates a continuous film that differs from the discontinuous character when applying an emulsion.

As explained in more detail below, the preferred effective range of coco diethanolamide for aerosol preparations according to the present invention is 2.5 to

3.5% by weight. However, tests have shown that additives up to 10% by weight bring no reduction in the property and quality of the developed film. However, when it was added more than 10% by weight, it was found that the coating applied resulted in an undesirable thickness of generally lumpy, lumpy nature, so that a continuous unbroken film can no longer be produced beyond that limit.

This crucial, unexpected influence, which is generated by the coco diethanolamide, is all the more visible and understandable when one realizes that the use of emulsifiers in emulsions has a predictable influence. It is known that numerous factors contribute to the relative stability or instability of a special emulsion. However, if in general the amount of emulsifier is below a predetermined value, the emulsion provided with this emulsifier will be in an unstable state with separate phases. When the emulsifier is added, the emulsion becomes relatively stable, the phases are mixed, and the appearance is homogeneous. A further addition of emulsifiers does not change the stability of the emulsion. For the purposes of the present invention, however, contrary to expectations, the further addition of cocodiethanolamide over approximately 2.5% by weight of the system destroys the previous stability, although it would have been expected, if a stable emulsion existed beforehand, that the further addition of the " Emulsifiers »Coco diethanolamide would have no effect. Therefore, this unusual and surprising behavior of this special agent supports the view that the system is no longer an emulsion with all of the various assumed emulsion properties, but instead becomes a dispersion with the cocodiethanolamide, which apparently ceases to act as an emulsifier. This makes the decisive influence of this agent in preparations such as those mentioned above obvious.

It must be noted that despite extensive tests, no other connection was found that has the required properties.

Active ingredients which are particularly suitable as an additive in aerosol preparations according to the present invention are water-insoluble. They contain the active phase of water-based paints, usually known as latex paints, which include, for example, acrylic emulsions, vinyl emulsions, vinyl copolymer acetate emulsions, alkyd emulsions and polyurethane emulsions. They also serve as casting solvents and lubricants, for example silicones, namely the alkyl polysiloxanes and polyorganosiloxanes, lecithin and other soy or animal fat derivatives, searates, telefluoromers, such as "Teflon" (trademark of EI DuPont de Nemours & Co ., Inc. for tetrafluoroethylene resins); also synthetic lubricants, such as butoxylated and ethoxylated glycols; also polybutene, which is used to tighten transmission belts, etc., and various common fats such as lithium stearate, calcium stearate, petroleum jelly, aluminum naphthalate and the like. Like. For use as lubricants, also mineral sealing oil, both penetrating and lubricating; furthermore, petroleum-based hydrocarbon oils and synthetic oils can be used to be incorporated into the preparations according to the present invention. Another category of active ingredients are waxes, including animal, such as beeswax or stearic acid, vegetable waxes, such as carnauba, myrtle and candelilla wax, as well as the various artificial or synthetic waxes, which are distilled from petroleum onto paraffin waxes. Base will be preserved.

Active ingredients for the formation of aerosol preparations according to the present invention are not exhaustive and are only selected, for example, from the range of compounds which, owing to the uniqueness of this invention, can now be sprayed in water-soluble systems, and enable a continuous film to be produced, which was previously the result of this process was considered impossible. All of these compositions or compounds are of the type which, when intended for use, enable the manufacture of an unbroken coating.

Accordingly, the area of application is infinitely large after it has been recognized that such preparations for the lubrication, the releasing of castings from molds, as adhesives, sealants, water displacement spray agents, for wax coatings, polymeric finishers, such as those used for floors and the like. Like surfaces are used, inks and dyes, asphalt beams, polyurethane coatings and paints can be used.

The special propellants which are used in aerosol preparations according to the present invention are the generally used types. They are liquefied, e.g. Hydrocarbons or halocarbons, such as fluorocarbons and mixtures thereof, or compressed gases, or combinations of liquefied and compressed gases. The choice of procedure depends on the desired properties with regard to evaporation speed, solubility, economy, pressure and safety. The well-known fluorocarbon 12 and fluorocarbon 114 are examples of halogen carbonate blowing agents that are equally effective. In general, the coal-hydrogen propellants are liquefied petroleum gases, such as propane, butane and isobutane, which are currently more popular than halogenated carbons because of the potential pollution.

Compressed gases are also used as fuel, such as carbon dioxide, nitrogen, nitrogen oxides and dimethyl ether. They can be used with the same ease as with other aerosol preparations, with the necessary caution, of course, when it comes to stability and pressure for certain areas of application.

It is clear that the selection of the propellant in the present invention is subject to the same judgments as for aerosol preparations in general. Therefore, the fuel as such does not form part of the present invention.

In order to ensure a sensible monitoring of the properties of the selected blowing agent, a large number of organic auxiliary solvents are used for the fuels, all of which belong to the known technology. Such solvents are used to control the rate of evaporation of the fuel, to prevent cracks in the applied finish film, and control of the rate of evaporation is also made possible by a selected combination of solvents which dry simultaneously with the active ingredients, the active additives. Among other things, such solvents are well known in aerosol application technology, e.g. aromatic hydrocarbons, such as benzene, toluene, xylene, commercially available solvents which ignite at 100 to 150 °, aliphates and aliphatic petro-leum naphthas, such as heptane, hexane, kerosene, paint liquefiers, naphthol alcohols, mineral sealing oil, mineral alcohols, odorless mineral alcohols, odorless kerosene, pentane, petroleum ether, Stoddard solvent, textile alcohols, VM&P Naptha, isoparaffinic hydrocarbons, as well as mixtures of these substances.

Another general class of auxiliary solvents are the chlorinated hydrocarbons. Among them, tetrachlorocarbon, 1,1,1-trichloroethane, methylene chloride and perchlorethylene are normally used.

In addition to these, which should not mean that they are now mentioned exhaustively as suitable auxiliary solvents, 5 tetra-hydrofuran and 2-nitropropane can also be used. As discussed above and included in the chemistry listed, the choice of solvent is made in accordance with well known criteria such as e.g. mastery of the evaporation rate, io compatibility with the special active ingredients etc. It should also be noted that such solvents can be mixed with one another in order to produce a desired property. The mixing of heptane and hexane is mentioned only illustratively, in that a mixture of these two et-15 dries slower than hexane alone, but faster than heptane alone.

The selection of the auxiliary solvent is judged by the same general considerations as are known in the aerosol art, so that the exact selection of the auxiliary solvent does not form part of the present invention.

Aerosol preparations which have the properties according to the present invention have the following general composition, with liquefied fuels, namely hydrocarbons and halogen carbons, being used:

The use of these compositions will become clearer when the specific compositions are discussed below. It should be noted, however, that the area of use of coco diethanolamide is clearly defined, as explained in detail above, and that

644148

Quantities of blowing agent and cosolvents fall into well known areas. Solvents therefore also fall into these well-known areas. Solvents in a proportion of less than 10% by weight have not proven to work effectively with the blowing agent. Similarly, amounts above 25% by weight appear to have an adverse effect on the effectiveness of the blowing agent. They also increase the likelihood of ignition. The assessment of the relative range with regard to the amounts of water added and the active ingredient can be better understood if these two components are taken into account together, so that they represent a combination, on average approximately 70 or slightly more% by weight of the entire system or preparation in which liquefied propellants are used. In compressed gas systems, the total amount of water and active ingredient is up to 85% by weight of the system.

This composition results in an applicable silicone casting dissolving preparation in which the active ingredient, although apparently only a small percentage by weight of the composition, forms a continuous film with water, which results in the mutual detachment of castings from the mold enables. It is interesting to note that in this preparation the isoparaffin hydrocarbon has a higher or higher rate of evaporation. A form that is commercially available is traded under the “ISO-PAR C” brand. It is an Exxon product.

This composition forms a shape that is useful for all well-known water-based paints. It should be noted that with this composition the water and water-based paint comprise essentially 61.2% by weight. They give the appropriate viscosity and hiding properties, which result in a good continuous and uninterrupted finish film. The isoparaffinic hydrocarbon is relatively colorless and flames at a temperature at which the evaporation does not break the finish film. A specially available product of this solvent is sold under the Exxon brand “ISOPAR L”. As mentioned above, a mixture of isobutane-propane is suitable as the blowing agent. It gives good pressure to spray. However, other blowing agents are just as effective, e.g. Fluorocarbon 12 and combinations of fluorocarbons 12 and 114 and others (Freon). Regardless of this, this unique composition gives the possibility of producing an unbroken film of the desired thickness, which has not previously been achievable in the aerosol spray field.

Example II (a)

In the following, for example, the composition of an aerosol preparation is specified, which is suitable as a release agent for castings from casting molds:

35 With this special composition, it should be noted that the blowing agent is a compressed gas, in the present case carbonic acid (C02). This is intended to demonstrate the effectiveness of the preparations in question, in which either a liquefied propellant or compressed gas is used as the propellant 40.

Example II (b)

The previous example shows a composition for separating castings and their molds, 45 silicone being the active ingredient. However, it is also possible to use preparations other than silicones for the purposes of the present invention as a means for loosening castings and molds. Such a composition is, for example:

With the compositions listed above, it should be emphasized that no reference was made to the inclusion of normal protective agents and anti-corrosion agents. However, the addition is within the scope of normal considerations and would be possible using the known techniques. The above compositions are intended to show how wide the field of application of active substances which are used in these products is, which, according to the present invention, allows the production of a continuous film. All the different blowing agents and auxiliary solvents, which are given as examples in the preceding recipes, are all equally effective, as are the corresponding components in the specific 30 examples, which only show the great effect of the present invention on the myriad uses.

It should be emphasized here that the majority of these preparations use hydrocarbons and carbon halogens as propellants, as are used in the broadest sense in aerosol technology. Compressed gases, as shown, are very useful as blowing agents, but with the present preparations only if the normal characteristics of these blowing agents are observed. Effective pressures for 4o nitrogen were found to be approximately 8.4 atu (approximately 2%) and for carbon oxide approximately 3.5 to 6.3 atü (approximately 2.5 to 5%). Nitrogen, although usable, has limited use due to the fact that its pressures are too high for the commonly available containers. Carbon dioxide would be the blowing agent of choice if the stability studies for each application showed that no carbonic acid was formed. As noted above, the propellants useful for the present invention may consist of a combination of liquefied and compressed gas, which are equally effective and, in many cases, economical.

The preparation of aerosol preparations in accordance with the present invention can be carried out very easily in the best known ways. All process steps 55 which have to be carried out can be carried out under normal ambient conditions. This prevents the need to control the environmental conditions.

One such procedure is as follows:

The drug phase is first prepared by weighing the corresponding amount of active ingredient together with the selected auxiliary solvent and the required amount of coco diethanolamide. The active ingredient phase is then shaken until the whole is in solution.

Then, with continuous shaking, the amount of water described above is added and further shaken to achieve a mixture of the phases. The delivery or aerosol container ultimately selected is then dispensed with the mixture in accordance with the known procedure.

Essentially immediately after spraying, a continuous film separating from the termination of the mixing movement separates the water foams and atomization products, as they have been achieved by the aerodynamic phase and the active substance phase, and so far remain in such separate sol formation of emulsions -t condition until shaken again immediately before the 5 and which preparation is anti-corrosive when spraying the preparation. In this way, the essentials are non-flammable or toxic, so that use for developing any of the large number of preparations does not have to be restricted and it is advisable in the sense of the present invention in previously unexpectedly large number of applications in an aero way, whereby these preparations are possible for production in large sol sector.
