Definitions
- the invention relates to improved detergent bar compositions having a variegated, striped or mottled appearance and a process for producing the same.
- Detergent compositions for fabric or hard surface cleaning typically comprise a surfactant system whose role is to assist in removal of soil. Such detergent compositions predominantly comprise non-soap surfactants. Various abrasives, fillers, builders, and other ingredients such as colour, perfume, preservatives, etc. may also be incorporated suitably.
- Variegated, striped, marbled or mottled soap bars have been known for many years and allow for more than one colour in the bar in specific or mosaic pattern.
- colouring materials such as bluing agents, which functioned as aids for the whitening of clothing.
- interest in such bars has been primarily due to the possibility of producing attractive designs therein, which would be preferred by consumers.
- Multicoloured soap bars are now mainly used for skin cleansing purpose.
- a marble pattern on soap gives it a rich appearance and stripes or other similar configurations make the soap distinctive.
- the manufacture of non-soapy striped detergent bars is more difficult than the production of striped soap bars by the methods used for striping soap bars.
- Striped soap bars are generally manufactured by (i) using different coloured soap or scarp soap (ii) extrusion of different strands of coloured soap through a die to get multicoloured bars (US-A-4, 196,163, Henkel) or (iii) injection of a fluid during the process of extrusion (US-A-3 , 890, 419, Armour- Dial, Inc. ) .
- Point (i) relates to the making of soap bars and the same has not been disclosed for NSD bars in literature. If scrap NSD bars were to be made as in point (i) , there would not be any integrity in the bar, as NSD bars have lesser binding force than the soap bar. NSD bars produced through point (i) would thus disintegrate and would not produce a proper striped bar. Therefore, it is not possible to employ the processes described in prior art for the manufacture of striped non-soap detergent bars used for fabric wash or hard surface cleaning. It is specifically advantageous to develop a process to manufacture non-soap detergent bars with stripes because such bars will give a visual cue and it gives a rich appearance, and stripes also make the detergent bar distinctive.
- a striped predominantly non-soap detergent bar composition comprising 5 to 50% by weight detergent active wherein the soap level is not greater than 25 % of the total detergent active, 0.1 to 10 % by weight of the said bar being a striping formulation comprising soap, non-soap or a mixture thereof.
- the said striping formulation comprises either 0 to 80% wt soap or 0 to 50% wt synthetic non-soap detergent or combinations thereof, with 5 to 30% wt water and 0 to 70% wt inorganic fillers .
- a striped predominantly non-soap detergent bar composition comprising 10 to 30 % by weight detergent active wherein the soap level is not greater than 10 % of the total detergent active, 1 to 5 % by weight of the bar being a striping formulation comprising soap, non-soap or a mixture thereof .
- striping is achieved by using a dough comprising 50 to 80% by weight of soap, 10 to 40% by weight of water and 0 to 20% by weight of inorganic fillers.
- the formulation may be prepared using preformed detergent actives or can be prepared by generating the actives by reacting the precursor of the detergent active with an alkali.
- a process for preparing a striped predominantly non-soap detergent bar composition comprising 5 to 50 % by weight detergent active wherein the soap level is not greater than 25 % by weight of the total active detergent, 1 to 5 % by weight of the bar being a striping formulation comprising soap, non- soap or a mixture thereof , which process comprises the steps of: i. reacting a precursor of the detergent active with an alkali . ii.
- the striping formulation is prepared separately by mixing soap, non-soap or a mixture optionally with upto 70% by weight inorganic particulates and converting the same into noodles.
- the essential feature of the invention is a striping detergent bar composition that comprises predominantly non-soap detergent actives and is striped with a striping formulation comprising soap or non-soap or a mixture.
- the detergent active is a mixture of the detergent active:
- the detergent active used in the bar is predominantly non-soap although some amount of soap can also be incorporated.
- the actives are selected from soap or non-soap actives that may be anionic, nonionic, cationic, zwitterionic or amphoteric in nature and it is particularly preferred that the soap level does not exceed 25% by weight of the composition.
- anionic and specific detergent actives used in detergent bar technology are described in literature, for example in Surface Active Agents and Detergents, Volume II by Schwartz, Perry and Berch (Interscience Publishers, N.Y. 1958) .
- Suitable anionic actives useful in this invention is soap or non soap selected from linear and branched alkyl benzene sulphonates, alkane sulphonates, secondary alcohol sulphates, primary alcohol sulphates, alpha olefin sulphonates, alkyl ether sulphates, fatty acyl ester sulphonates, alkyl carboxylates and mixtures of these.
- the term total fatty matter is used to denote the percentage by weight of fatty acid and triglyceride residues present in soaps without taking into account the accompanying cations .
- an accompanying sodium cation will generally amount to about 8% by weight.
- Other cations may be employed as desired for example zinc, potassium, magnesium, alkyl ammonium and aluminium.
- soap denotes salts of carboxylic fatty acids.
- the soap may be derived from any of the triglycerides conventionally used in soap manufacture - consequently the carboxylate anions in the soap may contain from 8 to 22 carbon atoms.
- the other detergent active compounds may be anionic, nonionic, cationic, zwitterionic or amphoteric surfactants, or mixtures thereof as are well known to those skilled in the art can also be incorporated in the formulation.
- the anionic detergent active comprises of alkyl benzene sulphonate (LAS) .
- the striping formulation The composition used for striping the bar may be entirely soap or non-soap and it is also possible to use a mixture of both soap and non-soap actives. It is preferred that the striping is to an extent of 0.1 to 10% by weight of the bar and more preferably 1 to 5% by weight of the bar. It is preferred that the striping formulation is achieved by using a dough comprising of 50 to 80% soap, 10 to 40% water and 0 to 20% inorganic fillers. In a typical example, the marbling formulation could be: 77% soap, 1% salt or inorganic fillers and 22% water.
- the detergency builders used in the formulation are preferably inorganic and suitable builders include, for example, alkali metal aluminosilicates (zeolites) , alkali metal carbonate, sodium tripolyphosphate (STPP) , tetrasodium pyrophosphate (TSPP) , citrates, sodium nitrilotriacetate (NTA) and combinations of these. Builders are suitably used in an amount ranging from 0 to 30%.
- Inorganic particulate phase is not an essential ingredient of the formulation but may be incorporated especially for hard surface cleaning compositions.
- the particulate phase comprises a particulate structurant and/or abrasive, which is insoluble in water.
- Suitable inorganic particulates can be selected from, particulate zeolites, calcites, dolomites, feldspars, silicas, silicates, other carbonates, bicarbonates, borates, sulphates and polymeric materials such as polyethylene .
- the most preferred inorganic particulates are calcium carbonate (as Calcite) , mixtures of calcium and magnesium carbonates (as dolomite) , sodium hydrogen carbonate, borax, sodium/potassium sulphate, zeolite, feldspars, talc, koalin and silica. Calcite, talc, kaolin, feldspar and dolomite and mixtures thereof are particularly preferred due to their low cost and colour.
- alumino silicate such as alumino silicate, boro-silicate structuring, boro-alumino silicate or calcium alumino silicate may be generated in situ or readily available forms can be incorporated.
- additives such as one or more water insoluble particulate materials such as polysaccharides such as starch or modified starches and celluloses may be incorporated.
- Minor and conventional ingredients preferably selected from enzymes, antiredeposition agents, fluorescers, colour, preservatives and perfumes, also bleaches, bleach precursors, bleach stabilisers, sequestrants, soil release agents (usually polymers) and other polymers may optionally be incorporated up to 10 wt%.
- the detergent formulation and the marbling formulation in the form of noodles are mixed during extrusion.
- the ratio of the torque of the striping formulation to the torque of the base formulation is maintained in the range 0.3 to 1.5.
- Detergent bars having a composition described in Table 1 was prepared by mixing the ingredients in the proportion mentioned and extruding the bar in a conventional manner.
- Comparative Example A no striping formulation was introduced where as Example 1 the striping formulation described in Table 1 was converted into noodles and introduced during extrusion.
- the ratio of the non-soap detergent formulation to the striping formulation was 95:5.
- Different torques were maintained by varying the moisture content of the marbling formulation. The torque was measured using a Rheocord -90 Haake.
- striping can be obtained if the torque of the striping base is in the range of 2 to 25 Nm, and the best striping is obtained if the torque in the range of 5 Nm - 10 Nm. Less than 2 Nm (obtained with striping material having higher moisture content) will give uniform smearing of the striping material on the surface of the bar, whereas greater than 25 Nm (obtained by drying off some moisture off the striping material) will give clumps of non-uniform colour intensity.
- Detergent bars having a composition described in Table 1 were prepared.
- Comparative Example B the 2% soap and 1% fluorescer was incorporated into the composition thoroughly mixed and in Example 2, 2% soap with 1% fluorescer was used to stripe the detergent bars .
- These bars were tested for fluorescer delivery on fabrics. Soiled fabric was washed using the bars of Comparative Example B and Example 2 and the fluorescer delivery benefit was measured by taking the difference in the reflectance of soiled and cleaned fabric at 460nm (R460) , with contribution from ultra-violet radiation incorporated. The measurements were carried out on a Macbeth Colour-eye 7000A reflectometer.
- the protocol used for detergency was as follows.
- the bars of Examples B and 2 were fixed in the rate of wear (ROW) j ig apparatus.
- WFK 10D cloth was cut into 10x30 cm swatches.
- the swatches were fixed on the trays and rubbed in a to and fro manner with the respective bar for 10 seconds in the ROW jig and then brushed for 10 sec.
- the fabrics were then rinsed three times with water, dried and the reflectance then measured.
- the data is presented in Table 4. The data shows that the striped bars showed enhanced fluorescer delivery as compared to the one where the ingredients were blended in the formulation.
