Definitions

• the present invention relates to a new paraffin composition and its use as a main constituent for candles with improved burning time, arranged in particular in a glass enclosure or other containers.
• paraffin composition suitable for use as a lighting candle in a verrine is a complex operation, since many parameters must be taken into account, such as the quality and the rate of combustion, the latter being directly related to the point. of paraffin fusion.
• the objective sought is, in fact, to obtain a complete, but as slow as possible, combustion of the combustible mass, including along the wall of the glass, with an illuminating and smokeless flame, despite the low speed. of combustion sought.
• a candle composition which burns in a regular manner producing a luminous flame, of a satisfactory height, and without fumes, which is not likely to extinguish following an insufficient air supply. .
• the combustion speed then becomes too high, which reduces the life of the candle, and it turns out to be necessary to incorporate, in the paraffin composition, an additive capable of reducing its combustion speed, without altering either the ability of the candle to melt at low temperature, nor the quality of its combustion, in particular, the absence of production of black smoke.
• the present invention proposes to solve and it aims to propose for this purpose a paraffin composition usable as a candle in verrines, or any other type of container, with a relatively large cross section, which lends itself to combustion. very slow and perfectly regular, and whose flame causes the fusion along its entire upper surface, even when the glass enclosure has large transverse dimensions, without causing emission of fumes.
• the invention also aims to provide such a paraffin composition, which, used in a verrine or a container of large dimensions, has a burning time much greater than that of the compositions of the prior art.
• the invention finally aims to provide a composition of this type, capable of burning over long periods without risk of extinction and without production of fumes.
• the subject of the invention is a paraffin composition which can be used as a candle with a long burning time, characterized in that it comprises:
• a copolymer of the monoolefin-vinyl ester type intended to limit the rate of melting of the paraffin, the content of which by weight in the paraffin composition is less than 10% and, preferably, less than 7.5%; - A complement to 100% by weight of the composition consisting of at least one paraffin having a melting point of less than 65 ° C, and preferably less than 58 ° C, and possibly, the usual additives in such compositions.
• methyl ester of at least one fatty acid it is advantageously possible to use a mixture of methyl esters of rapeseed.
• the copolymer used of the monoolefin-vinyl ester type is advantageously an ethylene vinyl acetate copolymer or in short E.V.A.
• the additives used may be present in amounts generally less than 10% and preferably less than 5% by weight of the paraffin composition and include a colorant, a perfume, an insecticide, a surface-improving agent composition or others.
• the complement to 100% of the composition is produced with a paraffin of petroleum or other origin, with a low melting point of less than
• the total burning time of such a paraffin-based composition, equipped with an appropriate wick, in a verrine or other cylindrical container of large diameter and great height can reach, or even exceed, 12 days without incident.
• the invention also relates to the use of such a paraffin composition in a verrine or other container.
• paraffin composition in accordance with the invention has the following formulation, in% by weight:
• E.V.A an ethylene vinyl acetate copolymer, abbreviated as E.V.A., intended to slow down the rate of combustion (trade name OKERIM® 5415 H or equivalent): 5%.
• Table 1 Characteristics of paraffin with a low melting point.
• the RADIA® 7961 used is a mixture of rapeseed methyl esters, the characteristics of which are given in Table 2.
• OKERIM® 5415H is a blend of E.V.A copolymers. , usually used as a modifier of the crystalline properties of hydrocarbon paraffins (see Table 3)
• a candle was made comprising a wick armed with tin number 3, the combustion speed of which is 3 g / h and which is housed in a 30 cm glass cylindrical container of height and 8.5 cm in diameter.
• the glass thus produced has a total burning time of at least 12 days.
• the combustion of the paraffin composition is complete, including along the glass wall, the heat of the flame proving sufficient to melt the composition along its entire upper surface.
• the resulting flame is bright and smoke-free and it lights up satisfactorily, despite the low rate of combustion of the composition.
