Definitions

  • the present invention relates to a bio-sourced composition for the manufacture of candles.
  • soybean wax was made from mixtures of soybean oil and beeswax or a mixture of coconut, palm and soybean oil....
  • liquid oils made it possible to no longer be dependent on concrete oils such as coconut (copra) or palm and palm kernel oils and to obtain "solid” oils capable of being used in the composition of candles.
  • compositions comprising palm oil and fatty alcohols have been described to address known flow and surface problems of palm oil-based candles.
  • compositions of renewable (bio-based) waxes are disclosed.
  • the composition of these candles comprises a fatty alcohol and according to another embodiment may comprise a fatty alcohol and a "vegetable-based wax".
  • the compositions described are free of alkanes, they all comprise ingredients derived from palm oil.
  • the fatty alcohols are derived from palmitic fatty acids and the majority of the compositions comprise palm "waxes" which are not clearly defined.
  • the aspects of certain compositions described seem to constitute counter-examples such as for example the "greasy and semi-transparent" aspect which cannot be the expected aspect.
  • the present invention makes it possible to solve all of the problems mentioned above and in particular both the problems of appearance of fragility and combustion and makes it possible to obtain candles comprising only completely bio-sourced ingredients and free of palm oil having performances at least equal to those obtained with waxes of mineral or animal origin and making it possible to comply with the standards EN15426, RAL GZ-041 EU Reach and ASTM title 16.
