Definitions

  • the present invention relates to a new composition of paraffin 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 which constitutes, possibly supplemented with different additives, must have a relatively slow burning rate, i.e. a slower consumption of hydrocarbon products.
  • this combustion must take place in a perfectly regular manner and homogeneous, so that the upper surface of the candle remains substantially flat and that it avoids presenting, at its upper part concave surface, sometimes with an accentuated hollow at the level of the wick candle. In the latter case, in fact, the amount of air becoming insufficient to supply the flame, combustion results incomplete fuel mass, up to extinction of flame.
  • paraffin composition suitable for a use as a candle in a verrine is an operation complex because many parameters have to be taken into account consideration, such as the quality and speed of combustion, this the latter being directly linked to the melting point of the paraffin.
  • EP-A-0 860 472 describes a paraffin composition for a candle, the paraffin having a melting point between 45 ° C and 65 ° C.
  • the objective sought is, in fact, to obtain complete combustion, but the slowest possible of the combustible mass, including the long of the glass wall, with an illuminating and smokeless flame, and this despite the low combustion speed sought.
  • a candle composition which burns in a regular manner by producing a luminous flame, of a satisfactory height, and without smoke, which is not likely to go out at following an insufficient air supply.
  • the invention also aims to provide such a paraffin composition, which, when used in a verrine or container large dimensions, has a burning time largely higher than that of the compositions of the prior art.
  • the invention finally aims to provide a composition of this type, able to burn over long periods without risk of extinction and without smoke production.
  • methyl ester of at least one fatty acid it is possible to advantageously use a mixture of rapeseed methyl esters.
  • the copolymer used of the monoolefin-vinyl ester type is advantageously an ethylene vinyl acetate copolymer or for short E.V.A ..
  • the additives used may be present in amounts generally less than 10% and preferably less than 5% in weight of the paraffin composition and include a colorant, a perfume, insecticide, agent for improving the surface finish of composition or others.
  • the complement to 100% of the composition is carried out with a paraffin of petroleum or other origin, with a low melting point below 65 ° C, and preferably less than 58 ° C, measured according to standard NFT 60-114.
  • the total burning time of such a composition based on paraffin, equipped with an appropriate wick, in a verrine or a 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.
  • Characteristics of paraffin with low melting point are collated in Table 1 Characteristics of paraffin with low melting point. Characteristics standards Values Fusion point NFT 60-114 50.1 ° C Needle penetration at 25 ° C NFT 60-123 16 x 1/10 mm Luchaire flash point NFT 60-103 204 ° C Oil content NFT 60-120 ⁇ 0.5% by mass
  • the RADIA® 7961 used is a mixture of rapeseed methyl esters, the characteristics of which are given in Table 2.
  • Rapeseed methyl esters Characteristics Methods Values Acid number AOCS Cd 3a-63 ⁇ 1 mg KOH / g Iodine value 105 to 120 / g / I 2 / 100g Water content AOCS Ca 2a-45 ⁇ 0.02% Free glycerol content AOCS Ca 14-65 ⁇ 0.03% Total glycerol content AOCS Ca 14-65 ⁇ 0.25% Appearance at 20 ° C Pale yellow oily liquid Pour point -10 ° C Cloud point 8 ° C Specific mass at 25 ° C 875 kg / m 3 Specific mass at 100 ° C 825 kg / m 3 Viscosity at 40 ° C 4.2mm 2 / s Flash point 180 ° C
  • OKERIM® 5415H is a mixture of EVA copolymers, usually used as a modifier of the crystalline properties of hydrocarbon paraffins (see Table 3) Blend of EVA copolymers Characteristics standards Values Freezing point ASTM D938 59-65 ° C Penetration at 25 ° C ASTM D1321 12-18 dmm Penetration at 43.3 ° C ASTM D 1445 66-76 mm 2 / s Color Saybolt ASTM D 156 ⁇ 26
  • the glass thus produced has a total burning time at least 12 days.
  • the combustion of the paraffin composition is complete, including included along the glass wall, the heat of the flame being sufficient to melt the composition along its entire surface higher.
  • the resulting flame is bright and smoke-free and it lights up satisfactorily, despite the low rate of combustion of the composition.
