Definitions

  • the present invention relates to the production of fragrance-containing wax formulations in which the fragrance is dispersed in high concentration and which are present as free-flowing particles.
  • Solid, free-flowing, fragrance-containing waxes lead to manufacturing and product advantages, particularly in the manufacture of scented candles. For example, a significant proportion of the candles are made using the powder pressing process
  • the wax mixture which is in powder, chip or granulate form, is pressed in an extruder with a wick to form an endless strand and cut to length, or the wax mixture is press-molded in stamp presses around the wick inserted with tubular needles.
  • Fragrance substances can generally only be introduced by means of immersion, which is followed by pressing.
  • the dipping mass again essentially consists of a wax component, since the solubility of fragrance substances in waxes is generally only very low, the concentration of the fragrance substances is only about 2 to 3 percent by volume. Due to the strong temperature dependence of the solubility of fragrances in waxes, the fragrance can also be displaced when the liquid wax cools or crystallizes out, so that the fragrance is predominantly on the surface.
  • the wax particles according to the invention can be produced with a wax which has a higher melting point than the wax melt present in the candle-drawing process. It is therefore by means of the wax particles according to the invention not only possible to introduce the fragrances into the wax melt with considerably lower losses, but also to distribute them homogeneously in the wax melt and thus in the candle strand.
  • oily fragrances can act as release agents and, for example, complicate further processing in pressing processes, such as are used in the case of soaps, candles, etc., with regard to the strength of a shaped body or lead to undesirably high tack on its surface.
  • fragrance substances in a solvent containing an ester and in turn to introduce or dissolve the solution in paraffin.
  • the fragrance content of a solution prepared in this way can be more than 10% by weight and up to 80% by weight.
  • Liquid or oily fragrance substances can be solidified in a simple manner by introducing them into an organic ester.
  • the production of paraffin-based objects, in particular candles, is based on the mixture of the fragrance concentrate described above with paraffin with a setting point below 55 ° C.
  • the fragrance content is with a preferred upper limit of
  • WO95 / 28912 describes a production route for encapsulated sunscreens.
  • the matrix material is melted.
  • a component that absorbs UV light is then mixed in.
  • the melt is emulsified in an aqueous medium which contains a surface-active substance.
  • the size of the emulsion drops is in the range between 0.01 and 100 ⁇ m.
  • the emulsion is cooled to room temperature.
  • the resulting particles are also in the size range between 0.01 and 100 ⁇ m.
  • fragrance-containing wax powder can not only be mixed with the candle wax, but also with additives such as. B. dyes.
  • the burning behavior should not be adversely affected.
  • Fragrance-containing wax formulations were found which contain wax particles with a diameter of 1 to 500 ⁇ m, a fragrance content of 1 to 80% by weight and an emulsifier content of 0.1 to 10% by weight.
  • the wax formulations according to the invention fix the fragrance, so that, in particular in the powder pressing or extrusion process, the handling of raw materials is made considerably easier, the distribution of the fragrance in the pressings is largely homogeneous and there is less loss / emission of fragrance.
  • the compactness is sufficiently high; the fragrance does not act as a release agent and does not separate on the surface.
  • Fragrance-containing wax formulations containing wax particles with a diameter of 10 to 200 ⁇ m, a fragrance content of 30 to 60% by weight and an emulsifier content of 0.5 to 2% by weight are preferred.
  • Waxes for the wax formulations according to the invention are natural, chemically modified and synthetic waxes or other fuel.
  • Natural waxes can be of vegetable (eg camauba wax) or animal (eg beeswax) origin.
  • the category of natural waxes also includes mineral waxes, such as ceresin, and petrochemical waxes, such as Paraffin waxes (hydrocarbon mixtures), micro waxes etc.
  • the chemically modified waxes include hard waxes, such as montan ester waxes.
  • synthetic waxes include polyalkyl waxes or polyethylene waxes.
  • synthetic waxes can also be produced by esterifying fatty acids of vegetable origin and alcohols.
  • Fuel masses can be, for example, solid or hardened vegetable fats or fats of animal origin.
  • Preferred waxes for the wax formulations according to the invention are stearins and paraffins.
  • fragrances for the wax formulations according to the invention can be found, for example, in S. Arctander, Perfume and Flavor Materials, Vol. I and II, Montclair, NJ, 1969, Dverlag or K. Bauer, D. Garbe and H. Surburg, Common Fragrance and Flavor Materials, 3 rd . Ed., Wiley-VCH, Weinheim 1997.

The candle is pressed into its final shape by means of piston pressure in the press cylinder. This process is carried out at approx. 18-20 ° C in a cold pressing process. After completing the Pressing the candle blanks (press blanks) are pushed out of the cylinder and fed to the candle dipping machine for further surface finishing.
  • Candles are produced as follows by the extrusion process using a piston extruder: 92-98% by weight paraffin or paraffin wax composition in powder form are homogeneously mixed with 4-8% by weight fragrance-containing powder according to Example 5 in the cold process. The mixed material is then fed to the reservoir on the piston extruder. From there, the material becomes one
  • the emerging candle strand is then cut to the desired length.
  • the candle head and foot are then milled to the desired shape.
  • the candle is fed to the diving machine for further surface finishing.
