FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10 and Rule 13) SHAPED TOILET BARS HINDUSTAN UNILEVER LIMITED, a company incorporated under the Indian Companies Act, 1913 and having its registered office at 165/166, Backbay Reclamation, Mumbai -400 020, Maharashtra, India The following specification particularly describes the invention and the manner in which it is to be performed Shaped Toilet Bars The present invention relates to a toilet bar suitable for cleansing. In particular, it relates to a toilet bar that has a specific formulation and plasticity or surface properties. Toilet bars are well known for providing a wide range of skin care and cleansing benefits and are frequently made available to consumers in aesthetically pleasing shapes. Toilet bars that contain high levels of soap and synthetic surfactants are excellent for cleaning and usually have sufficient hardness to be economically extruded into a billet and stamped into a final attractive shape. Stamping, however, does not provide for creating intricate three dimensional shapes. Toilet bars that are transparent or translucent and/or contain high levels of components that are liquid at room temperature are usually too soft to be stamped and must usually be cast in a shaped mould or frame from a flowable feedstock. Casting also has limitations regarding the creation of intricate shapes. The cast bar will often have at least one fiat surface upon hardening and will thus limit the choice of shape of the finished bar unless further process steps are employed to shape the flat surface(s). Additional steps will add to the complexity and cost of making such bars. Manufacturers have sought to provide to the consumer aesthetically pleasing shaped toilet bars that are shaped on their entire surface while attempting to meet a wide range of skin conditioning qualities, manufacturing and formulation constraints. A brief representation of the prior art is set forth below. U.S. Patent No. 3,856,449 issued to Fisher on Dec. 24, 1974 discloses a wire trimmer for trimming soap extrusions to obtain improved surface finish for soap. The cut lines will all be parallel to the direction of motion of the extruded soap. U.S. Patent No. 5,083,486 issued to Allison et al. on Jan. 28, 1992 discloses a method and apparatus for trimming non-soap solid stick deodorants to provide for a protruding rounded deodorant stick in the container. U.S, Patent No. 6,024,967 issued to Fattori et al. on Feb. 15, 2000 discloses a method and apparatus for shaping a top surface of a non-soap antiperspirant or deodorant product to have a compound-curved shape using a plurality of cutting blades. It has been discovered that three-dimensional shaping via cutting can be usefully employed to produce aesthetically pleasing bar shapes for specifically formulated toilet bars that unexpectedly possess a defined range of plasticity in order to produce a bar with an acceptable appearance (i.e. having minimal or no visually detectable surface defects such as cracks and gouges). Such plasticity can be quantified by the fracture initiation energy (Gic) and the fracture energy parameter (Gc) from a three-point bending test described below. Moreover, a specific range of yield stress (σy) was also unexpectedly found to be an important property for preparing a bar with an acceptable appearance after cutting i.e. avoiding surface defects, as well as for generally efficient processing of the inventive bar. The inventive bar was discovered to have a distinctive striated topographic pattern compared to bars shaped by stamping or casting, and this striated pattern can be quantified using microscopic analysis techniques described below.

Anionic Surfactants The inventive toilet bar composition optionally contains one or more non-soap anionic detergent(s) (syndets) as discussed above. The anionic detergent active which may be used may be aliphatic sulfonate(s), such as a primary alkane (e.g., C8-C22) sulfonate(s), primary aJkane (e.g., C8-C22) disulfonate(s), C8-C22 alkene sulfonate(s), C8-C22 hydroxyalkane sulfonate(s) or alkyl glyceryl ether sulfonate(s) (AGS); or aromatic sulfonate(s) such as alkyl benzene sulfonate.

Kic indicates the magnitude of the stresses around a crack tip. The higher the value of Kic, the greater the stresses. Units: Pa. Kic values are reported as kPa for convenience. Fracture initiation energy: where v is Poisson's ratio. Poisson's ratio is assumed to be 0.5, meaning that there is no change in the total billet volume during the fracture process. The fracture initiation energy is the energy required to initiate cracking. Units: J/m2 Plastic zone radius: The pfastic zone radius is a measurement of the size of the plastic region around the crack tip resulting from Kic. Materials with higher r values are more ductile (plastic) than those with lower r values. Units: m. Plastic zone radius values are reported as mm for convenience. Measurement of Gc by wire cutting: A simplified analysis of wire cutting yields the following equation: Where F is force exerted on wire as it cuts through the sample B is length of cut µ is coefficient of friction σy is yield stress d is wire diameter Therefore a plot of normalized cutting force vs. wire diameter should be a straight line having a slope of (1+µ)σy and an intercept of Gc. See: Kamyab I., Chakrabarti S., Williams J.G.; Cutting Cheese With Wire; J. Materials Sci.; 33, 2763-2770 (1998) incorporated herein by reference in its entirety. The fixture used for the wire test is illustrated in Figure 9A. The yoke assembly for securing and tensioning the wire fits into the crosshead of the Instron 5567 test machine. Stainless steel wires of various diameters were obtained from Malin Company (location Brook Park, OH). Wire diameters below about 0.03 cm were found to be impractical for use on soap billets/bars because of the tendency of the thin wire to break during the test. The upper limit of wire diameter is dependent on the particular test rig design used. The wire test was carried out by first equilibrating billets overnight at the desired test temperature in an oven, in the same way as was done for the 3-point bending test. Billets were then taken out one at a time and attached to the base of the test rig. The wire was positioned just above the billet; then the Instron crosshead was set in motion at 10 mm/min, with data logging to a computer. The Instron was stopped when the "plateau" region in the force vs. displacement curve was reached, which was usually when the wire had penetrated halfway through the billet. Five replicate tests were run on each billet. Three wire diameters were used: 0.020" (0.508 mm), 0.032" (0.813 mm), and 0.051" (1.295 mm)" Tests were run on three wire diameters for each of four temperatures (23.5, 30, 40, and 50°C) for a total of 60 individual tests. The width of the billet was checked at the midpoint of the depth for each test to get the F/B value (see above equation). The data were normalized to set the point of first contact between wire and billet at 0 force and 0 displacement. The normalized data were then pfotted to locate the "plateau value" of the cutting force. Surface analysis: A method was developed for quantitatively analyzing the surface topography of inventive and comparative skin cleansing bars, using both instrumental and image processing protocols described below. The instrument used comprises a stripe projector, micro-mirrors, and digital camera. Three dimensional scans of the bar to be tested are obtained by placement of the bar or bar segment on a stage. Visible stripe patterns are rapidly projected on the surface (<1 sec). Surface coordinates in all three dimensions are computed from the distortion of the stripe patterns and inputted to a computer for further analysis. A MATLAB algorithm (MathWorks, Natick, MA) was used to convert the surface patterns into feature vectors that were then inputted into a classifier routine. Images of each bar were obtained from three different areas, each 13 mm by 18 mm. The images were loaded into a database. An ~11 mm square was placed over each image, and the area outside the square was cropped away to remove artefacts and noise that occurs at the edges. A 5th order polynomial filter was applied to remove the waviness of the image. All image processing was done using MATLAB software. The texture of the images was enhanced by convoluting images with a Prewitt filter fit = [11 1; 0 0 0;-1 -1 -1]. The filtered images were used for calculating the directional variation array (DVA). The DVA in turn forms the input for a feature vector. The three feature vectors for the three areas scanned in each bar make up the feature matrix. The procedure is as follows: 1. Pre-processing 1.1. Input: Micrographic images (1024x768 pixels) as shown in Fig 6(a) were processed as described in section 1.3 below to yield an output image as shown in Fig. 6(b), an image of size 565x764 pixels with the horizontal texture enhanced. 1.2. Output: an image with size 565x764 pixels with the horizontal texture enhanced 1.3. Procedure 1.3.1. Cut the rectangular area of 567x766 pixels from the input image 1.3.2. Use Prewitt filter flt = [1 1 1; 0 0 0; -1 -1 -1] 1.3.3. Convolve the result of 1.3.1 with the filter in 1.3.2, take the valid range of the result with size 565x764 pixels as the output of pre-processing. Use the Matlab function conv2, the Matlab command to perform this function is outimg=conv2(inimg,f!t, 'valid'); where fit is the filter defined as above, and inimg and outimg are the input and output images, respectively. 2. Compute a Directional Variation Array (DVA) 2.1 Input: output from step 1.3.3. 2.2 Output; a DVA vector with length of 21 2.3 Procedure 2.3.1 Do the following steps 2.3.2 to 2.3.6 with ang ~ -10° to 10° 2.3.2. Rotate the pre-processed image to the angle ang, output is an image of varied size holding the rotated image with four triangle blank areas in its corners. 2.3.3 Calculate the mean along each of the line, parallel to the long axis, to get a mean array. Note: Do not take the blank area (caused by the rotation) into the mean computation. 2.3.4 Cut off the two ends and leave the center part (of length 561 pixels) of the mean array 2.3.5 Compute the SD (standard deviation) of the mean array 2.3.6 Take the output value of 2.3.5 as the N-th element in the DVA, where N=ang+11 Steps to compute one element in the DVA array from a rotated image are shown in Fig. 7 3. Compute feature vector based on the DVA 3.1 Input: output from step 2.3. 3.2 Output: a feature vector with length of 6 3.3 Procedure 3.3.1 Feature 1 = angO where DVA takes its maximum 3.3.2 Feature 2 = maximum of the DVA 3.3.3 Feature 3 = minimum of the DVA 3.3.4 Feature 4 = SD of the DVA 3.3.5 Feature 5 = frequency of the mean array at angle angO computed as follows ( 3.3.5.1 With angle equals angO, re-do the steps 2.3.2, 2.3.3, and 2.3.4. 3.3.5.2 Count the number of peaks in the resulting array as the frequency. The Matlab command codes to perform this function are mary(dsff(mary)~=0) = Q; peakjnum - sum(diff(diff(mary)>0)==1); where mary is the mary obtained from 3.3.5.1. 3.3.6 Feature 6 = frequency of the smoothed mean array at angle angO as follows 3.3.6.1 Same as 3.3.5.1. 3.3.6.2 Smooth the obtained mean array by (1D) convolution with filter [111]. The Matlab command codes to perform this function are Smoothed_mary=conv(mary,ones(3,1)); where mary is the mary obtained from 3.3.6.1. 3.3.6.3 Same as 3.3.5.2. Steps to create a Feature Vector, FV=(F1, F2, F3, F4, F5, F6), from one DVA are shown in Fig. 8 4. Classification 1.4. Input: a feature matrix FM, and associated truth value array t 1.4.1. For each sample image of the soap bars, get the output from step 3.3, a row vector of length 6 1.4.2. The collection of all such feature vectors form a vector matrix, with size Nx6, where N is the number of the samples. This is the input feature matrix FM. 1.4.3. t is a list (must be with length N) of 0 and 1 's telling whether a sample belongs to class 0 or class 1 4.2 Output: A classifier—a rule to discriminate different sample toilet bar images 4.3 Procedure 4.3.1 Create a classification tree T for predicting response t as a function of the feature matrix FM. The Matlab function treefit, the Matlab command code to perform this function is: T=treefit(FM, t, 'method', 'classification', 'splitmin' ,3); where FM and t are defined as above, and T is the output tree. 4.3.2. Analyze the tree, and decide the classifier. 4.3.2.1. View the tree with the help of the Matlab tools, the Matlab command codes to perform this function are FNAMES={'peak_angle', "sgm', 'max', 'min', 'freq 1', 'freq2'}; treedisp(t, 'names',FNAMES); 4.3.2.2. Examine the tree from the graphic display, each branch in the tree is labelled with its decision rule, and each terminal node is labelled with the predicted value for that node. A computer pointing device click on any node reveals more information about that node. 4.3.2.3. Ignore the lower levels of the tree if it has more than 3 levels, with the pop-up menu 'click to display' set to be 'class membership', right click the left and right nodes of the second level, to find out how much error would be caused if only the first level decision rule is used. 4.3.2.4. If the error rate is satisfied, output the rule, in the form of feature_name [> or <] critical value 5. Classifier 5.1. To determine if a soap sample was prepared by cutting or a non-cutting process such as casting or stamping the following procedure is used: 5.2. Do steps 1, 2, and 5.3. Do 3.3.4 (generally, do the step 3.3.x to compute the feature_name, as found in 4.3.2.3), and obtain a single value. If the resultant value is larger than 0.6493(generally, critical value), the sample will be classified as class 0 (inventive cut bar), otherwise it will befong to the comparative non-cut bar class.
