Definitions

  • the present invention relates to the field of multi-coloured cleaning articles, particularly soaps and extrudable non-soap cleaning articles, and methods for production of such multi-coloured cleaning articles.
  • the present invention is also applicable to extrudable articles such as laundry bars (also known as non-soap detergent bars).
  • Multi-coloured soaps and extrudable cleaning articles have been described by various terms including variageted, marbled, striated and striped.
  • Multi-coloured soaps within the ambit of the invention comprise a soap base and one or more coloured regions, achieving the appearance of spacial colour variation.
  • the soap base can be opaque or translucent, and may or may not be coloured itself.
  • the multi-coloured soap can be easily manufactured using inexpensive materials.
  • the manufacturing process should allow production of a multi-coloured soap with distinctive contras between different colours, particularly at the bar surface.
  • the addition of colour should not interfere with processes of forming the soap, e.g. pressing an extruded bar of soap to achieve a pre-defined texture or three-dimensional picture.
  • colouration of soap should not result in multi-coloured soaps tending to colour migration ("bleeding"), cracking for fissuring during storage or use.
  • the cleaning article is preferably a soap, such that the base mass is a soap mass, or generally a extrudable cleaning article and preferably a non-soap detergent article, such that the base mass is a non-soap detergent mass.
  • the invention is hereinafter described mainly for soaps, but is equally applicable to general extrudable cleaning articles and particularly to non-soap detergent articles such as, for example, non-soap cleaning bars, by substituting references to the soap or base mass by the respective extrudable base mass, e.g. a non-soap extrudable base mass.
  • the coloured particles according to the invention can be introduced to the soap mass at an initial mixing stage, after the milling process, prior to extrusion in a refining plodder and combinations thereof.
  • the temperatures of plodding and extrusion can vary and may be chosen appropriately in view of the melting point of the coloured particles.
  • the materials for forming the coloured particles may be chosen appropriately to conform to the extrusion and/or plodding temperatures. Since the coloured particles according to the invention can release their dye through conventional plodding and extrusion processes, no specialized equipment such as dye-injection modules, co-plodding soap appa- ratuses etc. are required.
  • the multi-coloured soaps according to the present invention can be produced in conventional double-barrel soap plodders as well as in single barrel soap plodders without vacuum chambers.
  • the invention thus allows to produce multi-coloured soaps without a high capital investment into specialized equipment.
  • the coloured particle according to the present invention preferably has a melting temperature, measured for the component with the highest melting temperature, of at least 45 0 C, preferably at least 55 0 C and most preferably at least 6O 0 C.
  • the upper limit for the melting temperature is preferably 7O 0 C.
  • the cleaning article is preferably formed using an extrusion or plodding step during which the base mass with added particle(s) is extruded or plodded at a temperature of at least 5 0 C lower than the melting temperature of the coloured particle(s).
  • the extrusion and/or plodding temperature is preferably at least 5 0 C below the lowest melting temperature of a particle "bleeding" of which is to be reduced or avoided.
  • the plodding or extrusion temperature generally is in the range of 30 to 6O 0 C, commonly in the range of 40 to 6O 0 C, preferably 45 to 5O 0 C.
  • the water-soluble component of a coloured particle preferably is or comprises a polyethylene glycol with an average molecular weight range of at least 1800, preferably at least 4000 and most preferably 5000 to 9000 g/mol, or a mixture of two or more such polyethylene glycols.
  • the water-soluble component preferably is a mixture of two or more of such polyethylene glycols, such that the melting temperature of the highest melting poylethylene glycol is between 45 0 C and 65 0 C. Therefore, the water soluble component preferably comprises a polyethylene glycol with an average molecular weight of at most 9000 g/mol.
  • polyethylene glycols with average molecular weights lower than 1800 g/mol tend to allow a fast release of the dye during forming of the soap - which is according to the invention generally done by plodding -, resulting in a nearly uniformly coloured soap if given enough time to release the dye. It is therefore preferred that the water-soluble component does not comprise a polyethylene glycol with an average molecular weight of less than 1800 g/mol.
  • Such high molecular weight polyethylene glycols have melting temperatures from 4O 0 C to 65 0 C.
  • the polyethylene glycols with higher molecular mass such as at least 4000 to 9000 or even 5000 to 9000 are particularly preferred. This allows to use in the process of the present invention coloured particles with melting temperatures above the extrusion and/or plodding temperatures of the soap forming step.
  • Polyethylene glycols preferably solid at room temperature (2O 0 C) with a weight average molecular weight (MW) of 1500 and above, can be obtained from BASF (Pluriol®), Clariant (Polyglykol®), Dow (CarbowaxTM) and various other suppliers.

  • fatty substances particularly allows to harness their super fatting properties as are known in the field of soap manufacturing.
  • Use of substances with a carbon chain length of more than 18 may introduce some grittiness into the soaps during washing and be perceived as rough to the skin.

  • Suitable commercially available transparent/translucent extruded fatty acid soaps are available from Uniqema and include Prisavon 1983 (Sodium Tallowate, Sodium Palm Kernelate, Water, Glycerin, Sorbitol, Tallow Acid, Palm Kernel Acid, Tetrasodium EDTA, Tetrasodium Etidronate) and Prisavon 1984 (Sodium Palmate, Sodium Palm Kernelate, Water, Glycerin, Sorbitol, Palm Acid, Palm Kenel Acid, Tetrasodium EDTA, Tetrasodium Etidronate).
  • Transparent/translucent extruded fatty acid soaps are also available from other regional soap manufacturers such as PT. Megasuryamas (Indonesia).
  • Transparent/translucent soap can also be converted from opaque soap of vegetable or tallow origin.
  • the process of converting opaque soap to transparent/translucent soap is well-documented in literature and involves extensive shearing of the soap base with adequate amounts of soap crystal retardant materials such as glycerine, sorbitol, polyethylene glycol, propylene glycol, alcohol etc.
  • the present invention is also applicable to combi-bars extruded from conventional soap plodders.
  • Combi-bars are hereby defined as a mixture of soap and surfactants. Combi- bars produced on conventional sigma mixers and soap plodders are carefully formulated to address the stickiness of the mixture due to the presence of surfactants that would otherwise pose problems in production. It is common to use dry, absorbent materials such as talc, kaolin, starch etc to address the stickiness in high-surfactants combi-bars. Alternatively, the combi-bar can have a higher soap to surfactant ratio for reasonable processing in conventional equipment.
  • the coloured particle according to the present invention comprises:
  • the soap according to the present invention comprises a total of 0,1 to 5 wt% of the coloured particles, preferably 0,5 to 2 wt%, based on the total of the soap.
  • mixture can be crushed in a blender or suitable device to form solid particles
  • Formulation 2 produced soaps with areas of varying contrast in colours. There are areas of intense yellow colour from the coloured particles against the blue colour of the soap.
  • Formulation 3 produced soaps with areas of varying contrast in colours. There are areas of intense yellow colour from the coloured particles against the blue colour of the soap.
  • Coloured particles B & C have polyethylene glycols with much higher melting points than Coloured particle A.
  • Formulations 6 and 7 used an oil-soluble colour dye as opposed to the water-soluble colour dye used in formulations 4 and 5.
  • the soaps showed varying contrast in colours with areas of intense colour from the coloured particles against surrounding lighter colour tones.
  • the soaps made according to formulation 7 retain much of the whiteness of the base soap indicating a lower degree of release for the colour dye from the coloured particle. This showed that the higher melting point of Polyethylene Glycol M. W. 9000 as against Polyethylene Glycol M. W. 6000 does exert an effect on the rate of release for the colour dye from the coloured particle.
  • the coloured particles can be used in a translucent soap base converted from an opaque soap base in a streamlined, procedural operation.
  • a common method, well-documented in literature, is to shear the opaque base with a blend of known soap crystal retardants in adequate quantities with sufficient heat till translucency is obtained in the soap mass.
  • an opaque soap base (Prisavon 9220 from Uniqema) with a blend of known soap crystal retardants and stearic acid is sheared in a jacketed sigma mixer with constant heat at 6O 0 C - 7O 0 C till translucency is obtained in the soap mass.
  • the shearing process is preferably conducted in a double-bladed sigma mixer with a counter- directional shearing action.
  • the perfume is added into the blend of soap crystal retardants to take advantage of the mixing and shearing process.
  • the coloured particles are introduced into the soap base at the initial mixing stage and processed under similar conditions. Both sets of soaps showed areas of contrasting intensity of colours. However, example 12 produced soaps whose primary base colour has taken on a slightly stronger bluish tone than soaps produced from example 11. The additional dye released from the coloured particles as a result of an increase in dosage showed that the colour effects in the soaps can also be manipulated by the amount of coloured particles used.
  • example 13 the same formulation as example 11 is used. However, the coloured particles are introduced into the soap mass at a later stage prior to extrusion.
  • the soaps produced by example 13 showed a whiter primary base colour with a stronger contrast against areas of intense colours in comparison with soaps produced by example 11. This example showed that manipulation in the stages for which the coloured particles are introduced into the soap mass can also influence the development of the coloured effects in the soap.
  • Figure 1 shows a corresponding soap.
  • Ethanol and water can be added to the base to enhance the translucency of the soap.
  • the soap samples showed areas of contrasting intensity of colours. This example showed that manipulation in the stages for which the coloured particles are introduced into the soap mass can also influence the development of the coloured effects in the soap.
  • Example 16 & 17 produced soaps with a lesser number of areas with high intense colours.
  • the soaps of Example 16 have a more gradual contrast of colour against the white background of the primary soap base.
  • the soaps of Example 17 have a more homogenous distribution of colour giving the soap a bluish shade against lesser white areas of the primary soap base.
  • the choice of solid fatty acids in the composition of the coloured particles can exert an influence on the distribution and release of the dye from the particles giving varied coloured effects on the surface of the soap.
  • mica is incorporated into the coloured particles for an added effect to the soaps.
  • the coloured effects are evident in both opaque and translucent soap.
  • the extruded detergent bar as depicted in figure 2, showed streaks of blue dye across the white primary base with areas of high-intense colours and soft tones.
  • the example demonstrated that the present invention is also applicable to the manufacture of detergent bar.
  • Example 21 The colour effects in soap are replicated in an example with the fatty acids replaced with glycol stearate (ester of ethylene glycol and stearic acid) in the composition of the coloured particles.
