Definitions

  • the present invention relates to a process for producing transparent soap material comprising one or more functional additives by subjecting shear-sensitive soap material to transparency-generating working as well as to transparent soap material comprising functional additives thus obtained, particularly shaped transparent soap bars, noodles or pellets.
  • Soap bars which are transparent have an aesthetic appeal to consumers, also because transparency is sometimes associated with "naturalness”. Therefore, there is a demand for transparent soap bars.
  • a production line for the manufacture of transparent soap bars usually comprises a mixer, then a multiple roller mill and a vacuum refiner/plodder, followed by a " cutter and a stamper.
  • a batch of soap is usually recirculated over part of the production line to impart sufficient shear energy to bring the soap into a transparent state.
  • the present invention relates to a process for producing transparent soap material comprising one or more functional additives by subjecting shear-sensitive soap material to transparency-generating shearing and working, which is characterized in that first the required degree of transparency is imparted to the soap material, after which an effective amount of the functional additive is mixed with the transparent soap material and, optionally, the final mixture obtained is converted into shaped form.
  • the final mixture may be converted into bars, noodles, pellets or any other suitable form or shape by methods known per se .
  • the functional additive may be selected from the group consisting of antioxidants, such as tocopherols, BHA, BHT and the like; chelating agents, such as EDTA and the like; colouring agents; deodorants; dyes; emollients; enzymes; foam boosters, which may be selected from anionic, amphoteric, nonionic and certain cationic surfactants, such as sodium cocoyl isethionate, sodium lauryl ether sulphate and the like; foam stabilizers; germicides; lathering agents; moisturizers; optical dyes; pearlescers; perfumes; sequestering agents; skin conditioners, such as dimerized fatty acids; solvents such as propylene glycol, glycerol, sorbitol, at least partially hydrogenated sugars and the like; stabilizers; superfatting agents, such as fatty acids; UV absorbers and mixtures of these functional additives.
  • antioxidants such as tocopherols, BHA, BHT and the like
  • the functional additives may be used in any desired quantity to effect the desired functional characteristics, and usually minor amounts from about 0.01% by weight up to 10% by weight are used. Some of the additives such as, for instance, foam boosters, foam stabilizers or solvents, may be used in larger amounts of up to 50% by weight or more.
  • the soap material comprises a mixture of soluble soaps and insoluble soaps.
  • soluble soaps are to be understood throughout this specification and the attached claims : the salts of saturated monocarboxylic acids or fatty acids having from 8 to 14 carbon atoms and additionally the salts of at least ono-unsaturated monocarboxylic or fatty acids having from 8 to 22 carbon atoms.
  • insoluble soaps are to be understood throughout this specification and the attached claims : the salts of saturated monocarboxylic or fatty acids having from 16 to 24 carbon atoms.
  • the salts of the monocarboxylic or fatty acids are preferably sodium salts, but small amounts of potassium soaps, ammonium soaps or alkanolamine soaps may also be present. The selection of the soaps depends on availability and cost, but suitable soaps are derived from coconut oil, palm kernel oil, tallow, hydrogenated tallow, palm oil, and the like and mixtures thereof.
  • the soap material may also comprise a crystallization modifier, such as hydroxystearic acid, polymerized unsaturated fatty acids, like dimerized and/or trimerized fatty acids, iso-stearic acid and their alkali metal soaps.
  • a crystallization modifier such as hydroxystearic acid, polymerized unsaturated fatty acids, like dimerized and/or trimerized fatty acids, iso-stearic acid and their alkali metal soaps.
  • the soap material may also comprise an effective amount of one or more synthetic or non-soap detergents, which may be of the anionic, nonionic, amphoteric or cationic type, or mixtures thereof. Usually, up to 25% by weight of the total composition of synthetic or non-soap detergent is used.
  • Suitable cationic detergents include quaternary ammonium compounds, such as stearyl dimethyl benzyl ammonium chloride, and the like.
  • Suitable amphoteric detergents include the alkyl- ⁇ - iminodipropionates and iminopropionates and long-chain imidazole derivatives.
  • Suitable anionic detergents include the alkyl aryl sulphonates, such as C 10 -C, 5 alkyl benzene sulphonates; the olefin sulphonate salts; the C n) -C 20 paraffin sulphonate salts; the C 8 -C 22 fatty acyl sarcosinates; the C 8 -C 22 fatty acyl isethionates and C ii -C 22 fatty acyl N-methyl taurides; the C ⁇ -C 22 fatty acid alkanol amides; the C 8 -C 20 alkyl sulphates and the sulphate esters of the reaction product of 1-20 moles of an alkylene oxide with 2 to 5 carbon atoms and a saturated, straight- or branched-chain aliphatic monohydric C 8 -C 20 alcohol, such as sodium lauryl ether sulphate.
  • alkyl aryl sulphonates such as
  • Suitable nonionic detergents include the reaction products of 1-50 moles of C 2 -C 4 alkylene oxide with C 8 -C 20 primary or secondary alkanols, with dihydric alcohols, and the like.
  • the shear-sensitive soap material is subjected to shearing and working in a manner known per se , such as according to European Patent Specification EP-B-0, 090,649 (Unilever) or United States Patent Specification US-A-2,970, 116 (Lever Brothers Company) .
  • the method according to the present invention has the following advantages : a higher level of perfume and also different types of perfumes can be incorporated, the final soap bar is less sticky so that higher stamping rates are possible, the form stability of the soap is better, there is less rework on the soap-manufacturing line and particularly this method offers a far greater flexibility in the further conversion into a finished soap bar than the prior art processes.
  • a soap formulation was prepared, consisting of: 56.4% by weight of sodium soap of palm oil fatty acids, 14.1% by weight of sodium soap of palm kernel fatty acids, 2.5% by weight of free palm oil fatty acids, 5% by weight of sorbitol, 7% by weight of glycerol and 15.1% by weight of water.
  • 1% by weight of perfume based on the weight of the soap present, was admixed.
  • the temperature of the composition was 22.5°C.
  • 5 Kg of the soap composition was passed once through a triple roll mill having a gap setting of 200 microns between roll 1 and roll 2 and 100 microns between roll 2 and roll 3.
  • the temperature of the composition after passage was 26.6°C.
  • the composition was passed through a laboratory Mazzoni M-100 duplex refiner/plodder with refining sieves of 0.5 mm and provided with a rectangular extrusion die of " 45 mm x 19 mm at the end of the conical outlet.
  • the cylinder temperatures were set at 30°C and the cone temperature was 57°C.
  • the speed of the plodder screw was fixed at 2.5 (related to rotation speed) .
  • the temperature of the composition after passage through the duplex refiner/plodder was 37.3°C.
  • the output velocity was 44.5 kg/h.
  • the transparency of a soap bar obtained from this composition was 1.8.
  • the transparency was evaluated by measuring the light absorption of a slice of soap having a thickness of 18.5 mm and expressing this value as a percentage of the light transmission of a matted glass standard, using a reflectometer according to Dr B.Lange, Type LMG 008.
  • the transmission of the standard compared to air is 8.3% and this value is taken as 100% throughout the measurements.
  • a transparency value of 15 is generally rated as acceptable for transparent soaps.
  • the same soap composition (without added perfume) was first imparted a transparency value of 8.3 by passing it 4 times through the laboratory Mazzoni M-100 duplex refiner/plodder, and 5 kg of this transparent soap having a moisture content of 13.4% by weight was mixed with the same amount of perfume of the same type as previously mentioned. After mixing, the temperature of the soap composition was 21.4°C. After 1 passage through the triple roll mill, the temperature of the soap composition was 27.5°C and after 1 passage through the duplex refiner/plodder the temperature was 37.1°C. The transparency of a soap bar obtained from this composition was 24.9 and the output velocity was 55.8 kg/h.
  • Example II Mazzoni M-100 refiner/plodder with refining sieves of 0.5 mm and having the same die as in Example I.
  • the cylinder temperature was set at 30°C and the cone temperature was 57°C.
  • the speed of the plodder screw was fixed at 2.5 (related to rotation speed) .
  • the output velocity was 24.8 kg/h and the final transparency of the soap was 4.5 (measured with a 20 mm thickness soap bar) .
  • the output velocity was 43.6 kg/h and the final transparency was 45.5 (measured with a 20 mm thickness soap bar) .
