Definitions

  • This invention relates to the processing of soap-containing feedstocks to introduce volatile components, for example perfumes.
  • a cavity transfer mixer provides an efficient route for incorporation because the processing temperatures are maintained, in general, below those usually encountered in soap processing. The processing time is low and the mixing occurs in an enclosed volume. The energy required will normally be lower than that required in conventional processes.
  • the present invention uses a device of the cavity transfer mixer class to introduce a volatile component into the soap base.
  • These devices comprise two closely spaced mutually displaceable surfaces each having a pattern of cavities which overlap during movement of the surfaces so that the material moved between the surfaces traces a path through cavities alternately in each surface so that the bulk of the material passes through the shear zone generated in the material by displacement of the surfaces.
  • Cavity transfer mixers are normally prepared with a cylindrical geometry and in the preferred devices for this process the cavities are arranged to give constantly available but changing ways path through the device during mutual movement of the two surfaces.
  • the devices having a cylindrical geometry can comprise a stator within which is journalled a rotor; the opposing faces of the stator and rotor carry the cavities through which the material passes during its passage through the device.
  • the temperature of processing is preferably from about 30°C to about 55°C, more preferably below about 40°C.
  • the device may also have a planar geometry in which opposed plane surfaces having patterns of cavities would be moved mutually, for example by rotation of one plane, so that material introduced between the surfaces at the point of rotation would move outwards and travel alternately between cavities on each surface.
  • auxiliary equipment As the rotor is turned.
  • auxiliary equipment are screw extruders and piston rams.
  • the auxiliary equipment is preferably operated separately from the mixer so that the throughput and work performed on it can be separately varied.
  • the separate operation may be carried out by arranging the auxiliary equipment to provide material for processing at an angle to the centre line of the shear-producing device. This arrangement allows rotational energy to be supplied to the device producing shear around its centre line. An in-line arrangement is more easily achieved when the external member of the device is the rotor. Separate operation of the device and auxiliary equipment assists in providing control of the processing.
  • GB-A-930 339) disclose longitudinal slots in the two surfaces.
  • the stator and rotor may carry slots, for example six to twelve, spaced around their periphery and extending along their whole length.
  • EPA 0048590 describes a specific form of cavity transfer mixer and suggests its application in soap processing.
  • EPA 0090644 (83301762.7) describes the processing of a superfatted soap formulation to improve the properties.
  • EPA 0090645 (83301763.5) describes the processing of a physically soft soap feedstock to provide a hardened product.
  • EPA 0090646 (83301764.3) describes the processing of soap compositions to reduce grittiness.
  • EPA 0090648 (83301766.8) describes the aeration of a detergent formulation.
  • EPA 0090649 (83301767.6) describes the manufacture of a transparent soap composition and EPA 0090650 (83301768.4) describes the control of phases in soap containing compositions.
  • one or both surfaces are subjected to thermal control.
  • the process allows efficient heating/cooling of the materials to be achieved.
  • the soap-containing feedstock may contain non-soap detergents in amounts which would not interfere with the desired effect.
  • these actives are alkane sulphonates, alcohol sulphates, alkyl benzene sulphonates, alkyl sulphates, acyl isethionates, olefin sulphonates and ethoxylated alcohols.
  • the processed feedstock was made into bar form using standard stamping machinery.
  • Other product forms e.g., extruded particles (noodles) and beads can be prepared from the feedstock. Drawings
  • a cavity transfer mixer is shown in Figure 1 in longitudinal section. This comprises a hollow cylindrical stator member 1, a cylindrical rotor member 2 journalled for rotation within the stator with a sliding fit, the facing cylindrical surfaces of the rotor and stator carrying respective pluralities of parallel, circumferentially extending rows of cavities which are disposed with:
  • the pattern of cavities carried on the stator 3 and rotor 4 are illustrated on Figure 3.
  • the cavities 3 on the stator are shown hatched.
  • the overlap between patterns of cavities 3, 4 is also shown in Figure 2.
  • a liquid jacket 1A is provided for the application of temperature control by the passage of heating or cooling water.
  • a temperature control conduit 2A is provided in the rotor.
  • the material passing through the device moves through the cavities alternately on the opposing faces of the stator and rotor.
  • the cavities immediately behind those shown in section are indicated by dotted profiles on Figure 1 to allow the repeating pattern to be seen.
  • the material flow is divided between pairs of adjacent cavities on the same rotor or stator face because of the overlapping position of the cavities on the opposite stator or rotor face.
  • the whole or bulk of the material flow is subjected to considerable working during its passage through the shear zone generated by the mutual displacement of the stator and rotor surfaces.
  • the material is entrained for a short period in each cavity during passage and thus one of its velocity components is altered.
  • the mixer has a rotor radius of 2.54.cm with 36 hemispherical cavities (radius 0.9 cm) arranged in six rows of six cavities.
  • the internal surface of the stator carried seven rows of six cavities to provide cavity overlap at the entry and exit.
  • the material to be worked was injected into the device through channel 5, which communicates with the annular space between the rotor and stator, during operation by a screw extruder. The material left the device through nozzle 6.
  • the cavity transfer mixer of Figure 8 had the external cylinder 11 journalled for rotation about the central shaft 12. Temperature control jacket 13 and conduit were present but the latter is not shown because the cavities on the central shaft are shown in plan view while the rotor is sectioned.
  • the central stator (diameter 52 mm) had three rows 14 of three cavities with partial, i.e., half cavities at the entry and exit points. On the rotor there were four rows 15 of three cavities.
  • the cavities on the stator and rotor were elongate with a total arc dimension of 5.1 cm normal to the material flow with hemispherical section ends of 1.2 cm radius joined by a semicircular sectioned panel of the same radius.
  • the cavities were arranged in the pattern of Figure 7, i.e. with their long dimension normal to material flow.
  • the rotor was driven by a chain drive to external toothed wheel 16.
  • the mixer used the cavity pattern of Figure 3 and had a rotor radius of 2.54 cm with 36 hemispherical cavities (radius 0.9 cm) arranged in six rows of six cavities.
  • the internal surface of the stator carried seven rows of six cavities to provide cavity overlap at the entry and exit.
  • a tallow/coconut superfat feedstock 60/40/72 was prepared. 2-phenylethanol (1.0%) was added to this base in a ribbon mixer to coat the noodles with this volatile material.
  • the base was divided with the first half being treated in the cavity transfer extruder with the aid of a soap plodder and the second being subjected to conventional treatment. Tablets were stamped and analysed by gas chromatography of the head space. Results showed less of the volatile component was lost by the cavity transfer mixer route.
  • a tallow/coconut (80/20) soap with a glycerol content of 1.25% was used as base.
  • Limonene (1.5% on base) was added to a sample of soap in chip form and conventionally processed.
  • a second sample was mixed with the same quantity of limonene and passed through a device of Figure 1 having cavities of diameter 2.4 cm arranged with six cavities in a circumferential circle.
  • the stator carried four complete cavities and the rotor three complete cavities with two half cavities at each end.
  • the soap temperature was 25°C input and 35°C at exit with cooling applied to the stator and rotor.
  • the throughput was 400 g/minute from a soap plodder with the rotor operated at 35 r.p.m.
