Definitions

  • the invention relates to a candle made of a wax-like substance based on paraffin and with an ester component, the candle having a freezing point having.
  • the invention further relates to a method for producing a such a candle.
  • Such candles are already known in various embodiments.
  • the aim is to have a melting behavior that is as favorable as possible to reach such a candle. That means that even with candles with relative large diameter, melting as possible over the entire Diameter takes place so that none during the candle burning Hollow structures arise which lead to the extinguishing of the candle or a It is very difficult to re-light the candle.
  • DD-A-224 334 describes candles which have an ester component and one Paraffin component with a solidification point of 47 ° C to 50 ° C exhibit.
  • the candles formed from this have a freezing point of 47 up to 63 ° C.
  • the invention deals with the technical problem, specify a suitable candle when using low-baked paraffin, which still has good melting behavior even with a large diameter shows, and a related manufacturing process.
  • paraffin With regard to the paraffin, one also speaks of low-boned paraffin.
  • the paraffin content mentioned has a very low hardness in the temperature range of a solidification point of 20 to 45 ° C. At approx. 40 ° C, for example, there is only a paste-like substance.
  • the proportion of organic ester or the ester-wax acid mixture already has a very considerable hardness at temperatures of 30 ° C. or less. For example. shows both hardened palm oil and hardened beef tallow, both substances that fall under the terms mentioned, a penetration of 6 mm -1 at 30 ° C.
  • paraffin here refers to technical paraffin, which is known to be obtained from petroleum, tars, in a partial synthesis or also by means of the Fischer-Tropsch synthesis. These are usually mixtures consisting of n-alkanes and isoalkanes of different carbon chain lengths, and the isoalkanes additionally have different structures.
  • the proportion of iso-paraffins in the mixture is more preferably 40% or more, particularly preferably 50% or more.
  • These iso-paraffins suitably have a C chain length of approximately C 16 to approximately C 45, with a maximum between C 26 and C 34. Such a paraffin portion has a solidification point below 45 ° C.
  • the above-mentioned mixture of paraffin with an organic ester and / or an ester-waxic acid mixture leads to a waxy substance which on the one hand has a hardness that is still acceptable for the desired products, but on the other hand also shows very good melting behavior.
  • Candles can be produced which, even with large dimensions in cross-section, lead to a uniform melting behavior across the cross-section. They then have an advantageous burning behavior.
  • the proportion of organic ester and / or ester-wax acid mixture in the waxy substance can be composed individually or as a mixture of the palm oil already mentioned, further of palm stearin, palm kernel oil, rapeseed oil, animal tallow, etc.
  • the compound class of the ester-wax acid mixture includes especially montan waxes, beeswax, carnauba wax, etc. These are long-chain esters. It is important that both the organic esters and the ester-wax acid mixtures have a high oil-binding capacity. However, this is designed differently in each case.
  • This property of the substance classes mentioned is particularly advantageous with regard to the substance described here, since the paraffin component with a solidification point of 20 to 45 ° C. has a certain oil proportion which increases with decreasing solidification points.
  • the paraffin portion can have a solidification point down to about 30 ° C. A solidification point of the paraffin portion in the range from 30 to 45 ° C. is preferred.
  • the proportion of paraffin in the waxy substance described here is in the range from 45 to 95%.
  • organic esters For example, fatty acid glycerides, wax acid esters or the montan waxes mentioned are also used.
  • the organic esters or montan waxes can also be saponified his.
  • Another example is triglycerides. As is known, these contain glycerin as alcohol. Such Alcohols with few carbon atoms, below 10 C atoms are preferred in the context of the invention (glycerol: 3 carbon atoms).
  • esters or Ester / wax acid mixtures all have a content of C-16 compounds, for example a palmite content of at least 5%, preferably more than 25%.
  • the invention also relates to a method for Making a candle in one of the previously described embodiments in this connection is based on the fact that in the course of paraffin refining preserved low-boned paraffin with a solidification point of 45 ° C with an organic Ester or an ester-wax acid mixture added with the organic ester or ester-wax acid mixture a solidification point of 35 to 70 ° C having.
  • the proportion of organic Esters or ester-wax acid mixture which further include individual substances already mentioned above.
  • a mixture of 80% paraffinic, paste-like content with 20% palm oil which has a penetration at 30 ° C of 6 mm -1 , resulted in a waxy substance with a solidification point of 37 ° C and a penetration at 30 ° C of 134 mm -1 .
  • a mixture of 80% paraffinic, paste-like content with 20% palm oil which has a penetration at 30 ° C of 6 mm -1 , resulted in a waxy substance with a solidification point of 37 ° C and a penetration at 30 ° C of 134 mm -1 .
