Description

PROCEDURE FOR THE MANUFACTURE OF A PURPOSE-BASED OBJECT BASED ON PARAFFIN FIELD OF THE INVENTION The invention relates first of all to a process for the manufacture of a paraffin-based object, in particular a candle, with a portion of perfume.

BACKGROUND OF THE INVENTION This type of manufacturing procedures are known. For example, with the main paraffin material of a candle, for example, an etheric oil is mixed. However, due to the very low solubility of these perfumes in the paraffin, it is not possible to achieve more than a concentration of 2-3%, based on the volume, in a candle like this with respect to perfumes. In addition, the solubility of perfumes in paraffin is strongly dependent on temperature. If perfumes are introduced into the liquid paraffin, there is also the danger that when the paraffin crystallizes, the perfumes are expelled from the system of substances. The perfumes can be deposited as an oily film on the outer layer of the candle. To achieve a particular desired aroma, as is known, a large number of perfumes are usually mixed as individual compounds. Typically, 20 to 40 individual perfumes are combined to obtain a particular aroma. The mixture is made in a solvent, which can itself be a perfume, or be odorless. This solvent, as regards its fixing effect of individual perfumes, is also referred to as a fixative. The concentration in the fixative can be different. In the context of the present application, it is adjusted according to the weight portion of the perfumes themselves. A considerable part of candles is manufactured technologically according to the powder compression procedure. In this case it is only possible to introduce perfumes by providing a compressed piece of paraffin of a respective layer by immersion, in which the perfume is included. The dip layer also consists essentially of paraffin. However, in the same way as before, here too the low solubility already mentioned of paraffin perfumes sets the limits. Therefore, according to this method, only a very low concentration of perfume, or a very low perfume portion referred to the total mass of a candle manufactured in this way can be achieved. Attempts have also been made to introduce perfumes, which are usually presented as an oily substance, by spraying solidified paraffin material, namely paraffin powder particles. However, in a subsequent compression process it turned out that the liquid perfumes, in the compression process, act as separation agents between the paraffin particles and, therefore, the compressed pieces can not be obtained with the desired solidity.

OBJECTIVES AND ADVANTAGES OF THE INVENTION Taking into account the state of the art indicated above, the invention has as a technical objective the provision of a process in which in a paraffin-based object, in particular a candle, a desired high concentration can be achieved of perfume. In addition, the invention deals with the technical problem of providing an advantageous perfume concentrate. Beyond, also of a paraffin-based object, with a high portion of perfume. This technical problem is solved first and essentially with the object of claim 1, the perfume having to be dissolved in an ester-containing solvent, in particular an organic ester, for example, triglyceride, and the solution thus obtained, on the other hand, Is incorporated or dissolved in the paraffin. It was observed that liquid or oily perfume substances, such as in particular essential oils, can be fixed in a simple manner when incorporated into an organic ester. Said organic ester can be individual or be a mixture of components such as palm oil, palm stearin, palm kernel oil, rapeseed oil or animal tallow. The term "perfume" that is used here not only includes natural products, as for example, essential oils, but also synthetic perfumes. In addition, also all those organic substances that have their own smell. A perfume concentrate obtained as indicated above, that is, a solution of a perfume oil or a perfume liquid in an ester, is then in solid form. The physical properties of a perfume concentrate thus obtained agree approximately with a mixture of 80% paraffin in paste with approximately 20% palm oil, in particular a palm oil which at approximately 30 ° C has a penetration of 6 mm " 1. Thus, a concentrate of perfumes such as this has all in all the property of a wax-like substance, with an essentially higher solidification point with respect to the oil portion of about 37 ° C and a penetration at 30 ° C. about 130 mm "1. The perfume concentrate is in solid form. The portion of perfume in the aforementioned solution can be more than 10% by weight and up to 80% by weight. It is also preferred that up to 50% by weight of the solution consists of microcera. Microwaxes, as it is known, are like paraffin mixtures of various hydrocarbons, but they mostly contain isoparaffins. It was surprising to observe that microwaxes advantageously influence the crystallization behavior of esters, in particular of triglycerides. In particular, the present invention relates to microwaxes which have a solidification point in the range of 68 ° C to 64 ° C, with a portion of isoparaffins of more than 75% and an oil content of more than 3.5%. A concentrate of perfumes obtained in this way can be easily incorporated into paraffin. For example, with respect to powder compression technology, it can be divided into small, powder-like components and, before compression, mixed with the mass of paraffin powder, so that a largely homogenous distribution is obtained of perfumes in a candle that is manufactured in this way. In the cited concentrate, a portion of perfumes of up to 60% is achieved. It is part of a portion by weight. The aforementioned perfume concentrate can be used not only in basic candle materials in the form of paste, but in principle in all candle raw materials, particularly in those paraffins, or in paraffin-based substances with a melting point of up to 105 ° C and / or a paraffin portion of at least 75%. With regard to the perfume concentrate, also unlike the above, it is preferred that it can also be incorporated in liquid form in the basic mass of the candle in liquid and then sprayed together with this basic candle mass for get a powder. The perfume concentrate, beyond the aforementioned 60%, may also possess a portion of up to 70% by weight of perfume oil. This corresponds to up to 35% (by weight) of perfumes in the finished product, the candle. A subject of the invention is also a perfume concentrate, which contains a portion of an ester, in particular an organic ester, such as, in particular, one based on triglycerides, such as, for example, palm oil, palm stearin, heart oil palm, rapeseed oil, tallow animal and / or a mixture of ester-acid wax, being contained in said perfume concentrate a perfume, in particular a perfume oil, such as for example, an etheric oil. An ester-wax acid mixture may also be contained, which, as a mixture, may be composed of fatty acid glycerides, wax acid ester, mountain waxes or the like. The portion of perfumes or perfume oils in this mixture can be between 20 and 80%, preferably one third to two thirds, based on weight. In another embodiment it is also preferred that the portion remaining after the perfume of one-third to two-thirds, based on the weight, consists of up to 50% of a micro-slice (microcrystalline waxor, paraffin). As regards the term microcera, it also refers to the embodiments indicated above. The perfumes, or the perfume oil, is preferably dissolved in the ester, or the aforementioned modifications and / or the microwell portion. Another subject of the invention is a paraffin-based object with a high portion of perfumes, for example, a candle. This object is characterized in that it consists of a wax-like substance with an organic ester portion and / or an ester-wax acid mixture, the paraffin portion as such having a solidification point of 55 ° C or less and the ester as such a solidification point of 35 ° C or more, and wherein, in addition, a portion of perfumes of 3% or more, in particular 5%, based on weight is contained in the object. The currently preferred upper limit is 35%. With regard to paraffin, low-burr paraffin is also referred to here. The mentioned paraffin portion, in the temperature range of a solidification point of 55 ° C or less, has a very low hardness. At approx. 40 ° C, for example, - you only have a pasty substance. On the other hand, the portion of organic ester or wax ester-acid mixture, already at temperatures of 30 ° or less, has a considerable hardness.

For example, both hardened palm oil and beef suet, both materials that fall within the above terms, at 30 ° have a penetration of 6 mm "1. The term" paraffin "is understood here as the technical paraffin, which, as is known, is obtained from petroleum, tars, in a partial synthesis or also by means of the Fischer-Tropsch synthesis.They are usually mixtures consisting of n-alkanes and iso-alkanes of various lengths of chains of carbon atoms. carbon, and in the case of iso-alkanes, in addition to different structures.The object may also contain a portion of microwaxes.The microwell portion (see in this respect also the above-mentioned embodiments) in the object, for example, the candle, it can be up to 30% It was surprising to observe that the aforementioned mixture of paraffin with organic ester and / or a micro-portion, results in a wax type material, which on the one hand has a hardness still to acceptable for the intended products, and on the other, it also shows a very good fusion behavior. Because the ester portion, or the micro-portion itself, has a high portion of perfumes, for example, up to 60% since, moreover, it is evenly distributed in the candle or the object made of paraffin, said object has altogether a portion of relatively high perfume, which is distributed homogeneously. Seen microscopically, it could also be observed that the perfume portion is concentrated in the ester and / or the microcera. The paraffin portion may consist in particular of a mixture of iso-paraffins and n-paraffins. Within this mixture, the iso portion is at least 50% with a carbon chain length of C 16 to C 45 and a maximum between C 26 and C 34. This portion of paraffin has a solidification point preferably below of 45 °. The organic esters, or wax ester-acid mixtures mentioned, are also very preferably triglycerides. Candles can be manufactured which, in the case of large dimensions in the cross section, produce a unitary fusion behavior in the same. Thus, they have an advantageous combustion behavior. In particular, the organic ester portion and / or wax ester-acid mixture in the wax-like substance can be compounded individually or in a mixture of the aforementioned palm oil, in addition to palm stearin, palm kernel oil, palm oil, and the like. rapeseed, animal fat, etc. The classes of compounds of the ester-acid mixture of wax include in particular also mountain waxes, beeswax, carnauba wax, etc. It is in this case of long chain esters. It is relevant that both the organic esters and also the ester-acid-wax mixtures have a high capacity for oil formation. However, this is a bit different in each case. This property of the classes of substances mentioned, with respect to the substance described herein, is particularly advantageous, since the paraffin portion, with a solidification point of 55 ° or less, has a certain portion of oil that increases when the points decrease of solidification. The paraffin portion can have a solidification point of up to approx. 30 °. A solidification point of the paraffin portion in the range of 30 ° to 45 ° is preferred. The paraffin portion in the wax-like substance described herein is preferably in the range of 45 to 95%. As regards the group of substances of the organic esters, for example, fatty acid glycerides, wax esters or also the abovementioned molar waxes can be used. The organic esters, or the mountain waxes can also be saponified.

Examples: A paraffin with a certain portion of oil, with a solidification point of 36 ° C, was mixed with hardened palm oil, this one presenting a portion of an etheric oil of 30%. While the paraffin portion alone had a pasty character, after mixing with the hardened palm oil, which at 30 ° C presents a penetration of approximately 6 mm "1, in a ratio of 1: 1, a penetration at 30 ° C from a little less than 46 In another test, beef fat was added instead of hardened palm oil.It was obtained with the same proportion of mixture and the same portion of perfume, a penetration of a little less than 43%. mm "1. In contrast, in both cases the solidification points of the wax-like substance obtained only increased slightly with respect to the solidification point of the paraffin starting material. While the paraffin starting product has a solidification point of approximately 36 ° C, the mixture of 50% of paraffin portion and 50% of hardened palm oil, presented one of 39 ° C. The mixture of 50% paraffin portion and 50% hardened beef tallow presented a 40 ° C. A triglyceride was also mixed with a solidification point of approximately 50 ° C and a penetration of 6"1 mm at 30 ° C, with the same portion of micro-glass with a solidification point of 71.5 ° C and a penetration of 79" 1 mm. The mixing is carried out at approx. 80 ° C, that is, in the liquid state of both portions. The mixed substance obtained in this way, to which the perfumes are then added in the desired amount, has a solidification point of approx. 67 ° to 70 ° and a penetration of 211 mm at 25 ° C. In particular, a mixture of substances like this can be added later - again an equal portion of a liquid perfume (lemon).

With respect to the carrier material mixed with perfume, a solidification point of 65.5 ° C and a penetration of 71"1 mm at 25 ° is then obtained.All the disclosed properties are essential for the invention.In the disclosure of the application it is included with all its content also the disclosure content of the corresponding / attached priority documentation (copy of the previous application), also for the purpose of including properties of said documentation in claims of the present application.
