, Description:[002] Soap bars are generally used for the purposes of maintaining personal hygiene. According to the Bureau of Indian Standards (BIS), there are two major types of soaps available in the market: toilet soaps and bathing soaps. Toilet soaps often contain high percentage of fatty material ranging from 60% to 80% depending on the grade of toilet soap and on the other hand bathing soap bars have lesser fatty acid matter of around 40%.
[003] Transparent soap bars are categorized under bathing soap bars and are popular for its aesthetics and good sensorial properties. One important concern to be addressed while making transparent soap is that the other qualities of cleansing ability, rich lather, and longevity should not be compromised. The total fatty acid matter of a soap is composed of both soluble and insoluble fatty acids as soaps are generally made up of salts of fatty acids of C8 to C18 chain length. Apart from the salts of fatty acids, common surfactants like sodium lauryl sulfate, sodium laureth sulfate and cocamidopropyl betaine are used to modify the lathering properties of the soap bar. In order to obtain a transparent soap bar which is equally rated high in hardness, longevity, and lathering a balanced amount of solvents like glycerine, propylene glycol, triethanolamine, sorbitol, sucrose and water need to be used along with fatty acids, surfactants and electrolytes.
[004] Because of the ever-rising demand for vegetable oils and other sustainability concerns including high costs of these raw materials, the trend is shifting towards manufacture of soaps that employ lower amounts of fats. Such compositions with low Total Fatty Matter (TFM) comprise relatively higher levels of solvents. As a result, such bars are susceptible to high wear rate. Further, such soap bars prepared by such combinations are structurally soft. Still further, these soaps are also prone to exhibit high sweating rate (glycerine dew effect) upon usage in high humid conditions on account of higher amounts of glycerine. Therefore, it would be prudent to say that preparation of transparent soap bars is quite challenging as one should consider the qualities of hardness, transparency, and sweating at the same time to arrive at a good soap bar product. One also cannot ignore the high cost of formulation that goes into preparation of such soaps.
[005] There remains a void in inventing a composition that not only fares well on the sustainability front by lowering the amount of fatty acids, but also delivers on the sensorials along with properties equivalent or superior to available transparent soap bars. Thus, the object of the present invention is to provide a transparent soap bar which is hard, producing rich lather, low on sweating, low on wear rate and at the same time having good sensorial qualities.

[0097] The fatty acid components are contributed in the composition by hystric acid, coconut fatty acid, and lauric acid. The weight percentage of solvents is contributed by sorbitol, glycerin, and propylene glycol (PG). Sodium chloride (NaCl) is the electrolyte in the soap composition, while acetic acid is the optional transparency enhancer. SLES 1EO (anionic surfactant) and decyl glucoside (non-ionic surfactant) are the surfactants in the composition and EDTA and EHDP are the chelating agent, while BHT performs the role of an antioxidant.
[0098] The working examples have all the components in the working ranges as disclosed in Table 2 below:
Table 2: Working ranges of the components
Category Components Working Range
Total Soap Content Alkali metal salts of hystric acid, coconut fatty acid, and lauric acid 13% - 32.5% w.r.t total composition
Insoluble soap content Alkali metal salts of hystric acid, coconut fatty acid At least 61% w.r.t total soap content
Electrolyte NaCl 0.5% - 2% of the total composition
Solvents (Humectants) Glycerin, Sorbitol, and PG 35% - 45% of the total composition
Solvents (Humectants) Sorbitol At least 40% of the total solvent composition
Surfactant SLES 1EO and Decyl glucoside Combined weight percentage of 6% - 18% of the total composition
Water - 18% - 30% of the total composition

[0099] The working examples A1 to A7 varies in weight percentages of the essential constituents. A1 has the lowest weight percentage of total fatty matter and A7 has the highest weight percentage of total fatty matter with respect to the total soap composition. The example A8 displays the composition of the soap by using a combination of two surfactants – SLES 1EO (anionic) and decyl glucoside (non-ionic). Each one of the working example has at least 61% of insoluble soap content with respect to the total soap content in the composition. The total soap content in the composition is calculated by using a multiplication factor of 1.08 to the total fatty acid content. The minimum weight percentage of insoluble fatty acids varies from 11.19% in A1 to approximately 20% in A7 w.r.t total composition. The weight percentage of solvents varies from 33.1% w.r.t total composition in A7 to 38% w.r.t total composition in A2. It can also be appreciated that the example A2 has the highest weight percentage of sorbitol in it compared to the other working examples. Similarly, A1 has the lowest percentage of electrolyte (NaCl-0.5%) and A7 has the highest percentage of the electrolyte (2%). Thus, it can be observed that all the working examples are prepared using the constituents in the working ranges as mentioned above (Table 2).
[00100] It can be appreciated from Table 1 that all the working examples are rated high on transparency parameter, therefore, in spite of having high insoluble soap content (at least 61% w.r.t total soap) the working examples are able to maintain their transparent nature. It can also be observed that wear rate of the soap (A1 to A7) is inversely proportional to its hardness. The hardness of the soap follows a decreasing trend from A1 to A7, wherein lesser values of hardness in soaps is undesirable, whereas the wear rate decreases from A1 to A7, wherein lesser wear rate is desirable. The example A8 depicts a combination of two surfactants (SLES 1EO and decyl glucoside) which provides a better lather volume along with uncompromised transparency, mush parameter, and sweating parameter.
Although all of the working examples (A1 to A8) maintain high transparency and reasonable scale of other parameters, A3 and A8 are the best working examples which rate high on mush scale, lather volume, and transparency. The example A3 also ranks high in hardness scale therefore has a low wear rate. Thus, the examples fulfil all the parameters for a transparent soap.

[00102] Referring to Table 3, the examples A9 and A10 have weight percentage of soap outside the working range. Similarly, the examples A11 and A12 have weight percentage of solvent outside the working range. The examples A13 and A14 have weight percentage of electrolyte outside the working range, and the examples A15 and A16 have weight percentage of water outside the working range.
[00103] It can be appreciated that the example A9 has a low weight percentage of total soap content, around 11.88% w.r.t. total composition, which is lesser than the working range of total soap content. Thus, although the transparency is maintained but the wear rate is very high and also it is not acceptable in terms of sweating parameter and mushiness. The example A11 has a low weight percentage of total solvents, around 27.6% w.r.t total composition. Observing the parameters from the table, it can be appreciated that the composition A11 cannot be processed because of low solvent content. Thus, cannot be considered as an ideal soap composition. The example A13 has a low weight percentage of electrolyte (NaCl) around 0.3% w.r.t total composition, although it has an acceptable transparency and mushiness, however is unacceptable with regards to sweating property and hardness of the composition is also on a lower side. The example A14 is non-working w.r.t high electrolyte weight percentage (around 2.50%), it can be appreciated that although the sweating property is acceptable as compared to A13 (having less electrolyte weight percentage) but it still remains unacceptable in terms of its low level of lather production (only 270ml). The examples A15 and A16 depict that even varying levels of water content makes the composition unacceptable in terms of its transparency and hardness parameters.
[00104] The non-working examples clearly illustrate the importance of weight percentages of total soap content, solvent, electrolyte, and moisture in the preparation of a transparent soap bar having high sensorial features. It can be well appreciated that, preparing the compositions using weight percentages of different components outside the mentioned working ranges (Table 2) do not fulfil all the parameters required for preparing a transparent soap bar.
[00105] On comparing the working and non-working examples, it can be observed that the problem of unacceptable sweating in the compositions (A9, A10, A12, and A13) accompanied by high solvent weight percentage is countered by using unique combinations of solvents and low weight percentage of electrolyte in working examples such as A1 and A2 (Table 1). The problems in preparing a desirable transparent soap bar rated high on sensorial appeal have been addressed using various strategies. Thus, considerable research efforts are required to arrive at specific weight percentage ranges for different components that can be used for preparing a transparent soap bar having less wear rate, acceptable sweating and hardness parameters, high on mush scale and producing rich lather.

Example 3
Process for preparing a transparent soap bar
[00106] The present example highlights the specific process that can be used for preparing a transparent soap bar having all the desirable features as mentioned in the previous example sections.
[00107] The preparation process has been defined in a manner so as to distinguish the composition obtained after every step from the previous steps.
[00108] A combination of 50.0 g of coconut fatty acid, 170.0g of hystric acid, 40.0 g of lauric acid, 110.0 g of glycerin, 120.0 g of propylene glycol, 0.3 g of BHT, 0.6 g of tetra sodium EDTA, 0.75 g of EHDP were taken together in a reaction vessel and heated at a temperature of 700C with a stirring speed of 100 rpm till the fatty acid components melt. The temperature was increased from 700C to 900C, and the stirring speed was increased to 130 rpm after complete melting of fatty acids. The obtained mixture of Part A was further neutralized with 89g of 48% alkali solution to get Part B. Post complete neutralization, 15.0 g of sodium chloride in aqueous solution was added followed by the addition of 100.0 g of sodium lauryl ether sulfate, and 205.0 g of sorbitol to get part C. To the obtained Part C, 5.0 g of acetic acid (transparency enhancer), color components, fragrance, water was added to complete the soap making process. The molten mixture was casted in the molds and allowed to cool to room temperature in order to get desired transparent soap bar.
[00109] The component of transparency enhancer is optional, and components of fragrance, and color are and can be changed according to the demand of a particular type of soap composition in the market. The weight percentage of insoluble fatty acids, electrolyte, solvents, and surfactants are the essential ingredients and the process disclosed herein describes in detail the strategies adopted to prepare the soap having the desirable features using the essential ingredients.
[00110] Overall, different working and non-working examples are depicted in the present disclosure that highlight the importance of working ranges of important components used for preparing the soap. The examples are followed with a process described for preparation of the transparent soap bar having key qualities of transparency, mushiness, hardness along with other parameters.
Advantages of the present disclosure:
[00111] The present disclosure reveals a transparent soap composition which maintains its transparent property despite having high insoluble soap content. Also, the rate of wear is at par with conventionally known products despite having high amount of solvents. The disclosed soap composition at the same time has a high sensorial appeal as compared to other available transparent soap compositions. The soap composition has a low total soap content t, and within the low total soap content window, it has a high weight percentage of at least 61% w.r.t the total soap composition. The blend of such a fatty matter composition along with presence of high amount of solvents, and low amount of electrolytes results in a soap bar that exhibits enhanced key bar properties of hardness, mushiness, lather, transparency, low wear rate and acceptable sweating parameter.
