Specification

FIELD OF INVENTION
[001] The present disclosure broadly relates to field of personal hygiene and particularly relates to a translucent soap composition.
BACKGROUND OF INVENTION
[002] Translucent soap bars are commonly available in market. These bars are liked for their sensory appeal clubbed with pleasing aesthetics. However, cost effective preparation of translucent soap bars is a technical challenge. Especially so, because these soap bars need a specific mix of ingredients which lend them translucency without compromising on opaque soap like product sensorial such as creamy lather.
[003] Achieving specific translucency from commonly available ingredients is a challenge that the soap making industry routinely comes across. The weight percentage of humectants and soaps are generally crucial in achieving a translucent soap composition. Also, lot of onus lies in the process which is used for preparation of translucent soap composition. It is therefore pertinent to constantly strive for alternate compositions and alternate methods for preparing such translucent soap composition.
[004] Generally translucent soaps are made from soap noodles comprising humectants, such as, glycerine added at concentration of 8-10% and moisture present in concentration of 10-14%. Translucent soap bars made from such conventional soap noodles typically comprises moisture in the range of from 8 -11%. There is a continuous need felt in the art to successfully arrive at soap bars comprising significantly higher moisture concentrations. This is essentially because higher moisture levels in soap bars lend better sensorial capabilities to soap bar. [005] US20040043913A1 discloses a soap bar composition including a soap mixture, a polyalkylene glycol, at least one of glycerin and sorbitol, water; and optionally, free fatty acid. The soap bar composition exhibits translucent properties. [006] US6838420B2 discloses a translucent or transparent composition comprising soap, at least one synthetic surfactant, water, lower monohydric

alcohol, a humectant, a structurant, a gellant with the proviso that either of the structurant and gellant are always present in the composition. [007] In spite of availability of various translucent soap composition, efforts have been made continuously in the industry to achieve a translucent soap composition made using soap noodles comprising a higher moisture content and cheaper ingredients, such efforts have not been successful.

[0062] The disclosure will now be illustrated with working examples, which is intended to illustrate the working of disclosure and not intended to take restrictively to imply any limitations on the scope of the present disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice of the disclosed methods and compositions, the exemplary methods, devices and materials are described herein. It is to be understood that this disclosure is not limited to particular methods, and experimental conditions described, as such methods and conditions may apply. [0063] The following section details the working and non-working example with respect to the composition and also with respect to the process for preparing the soap composition. The examples have been compared with respect to the translucency of the soap composition, bar hardness, and processability of the composition.

Example 1
Working and Non-working examples with respect to the soap composition
[0064] The translucent soap composition as disclosed in the present disclosure includes the following components in the described weight percentages. The weight percentages mentioned below are with respect to the final translucent soap composition.
1. Soap noodle comprising:
a. First liquid component (12.76% to 20%) comprising:
i. Moisture in range of 12-17%
ii. Glycerine in the range of 0.76-2.55%
b. Solid mass in the range of 60-70%
2. Second liquid component comprising:
a. Bonded moisture from sodium silicate in the range of 1.0- 2.5 %
b. Glycerine in the range of 7-11 wt%
c. Optional additives in the range of 0.05 - 1.5 wt%
3. At least one solid surfactant (sodium olefin sulfate) in the range of 2 - 4%.
4. Sodium silicate having a weight percentage in range of 1-4%.
[0065] The translucent soap composition as described herein is categorized into a combined solid content and a combined liquid content in the following manner:
1. A combined solid content comprising: i) the solid mass, ii) sodium silicate, and iii) the at least one surfactant; and
2. A combined liquid content comprising: i) the first liquid component, and ii) the second liquid component.
[0066] One of the crucial aspects in the working example is the ratio of combined solid content to combined liquid content which is to be maintained in a range of 2:1 to 3:1; and wherein the translucent soap has a lux value in a range of 150 to 200. [0067] The solid mass comprises: (a) sodium salt of fatty acids selected from the group consisting of C8-C22 fatty acids, and combinations thereof having a weight

percentage in a range of 40-70% with respect to the solid mass; (b) surfactants having a weight percentage in the range of 2%-10% with respect to the solid mass, and c) sodium sulfate having a weight percentage in the range of 0.1%-0.6% with respect to the solid mass. The surfactants present in the solid mass can be selected from any commercial grade anionic surfactants, non-ionic surfactants, and combinations thereof well known in the art.
[0068] The soap noodles comprising solid mass was prepared by the following process: As described previously, soap noodles comprises solid mass (comprising sodium salt of fatty acids, surfactants, and sodium sulfate), and the first liquid component. Briefly, saponification or neutralization of fat blends or mixed fatty acid blend using caustic lay was done and after the completion of saponification, sodium sulfate was added, and consecutively surfactants were added in the soap crutcher at a higher temperature in the range of 100 to 180°C Further, the first liquid component was added to obtain the soap noodles. All commercial grade of anionic and non-ionic mix are applicable in this stage during the process of opaque soap noodle preparation.
[0069] Table 1 depicts the working and non-working example with respect to the composition.

[0070] Referring to Table 1, it can be appreciated that working example 1 has all the mentioned components within the working ranges. Thus, it can be observed that the example is giving a translucency value within 150-200 lux. The lux value of the opaque soap noodle on the other hand remains in the range of 10 - 20. The working example can be easily obtained by the disclosed process and has a bar hardness of about 3.1. Thus, the present working example provides a translucent soap composition having a desired bar hardness.
[0071] Table 1 depicts two non-working examples 1 and 2. Non-working example 1 has greater quantities of moisture (free and bonded) than that of claimed range. Also, it has greater quantities of glycerin beyond the disclosed range. Hence, the non-working example 1 is not processable amounting to be sticky which cannot be stamped. The present non-working example is also non-working with respect to the translucency value (lux) of 100 which is below the disclosed range of 150-200. Also, because of the overall higher liquid content, the ratio of combined solid to combined liquid content is below than the disclosed range of 2:1 to 3:1. [0072] Referring to Table 1, non-working example 2 has greater quantities of solid content in the example. The quantity of solid surfactant (8%) is more than the disclosed range, on the other hand quantity of glycerin (6%) is lesser than the disclosed range. Thus, the ratio of combined solid content to combined liquid content is 3.13:1 which is beyond the disclosed range of 2:1 to 3:1. Also, the bar hardness is beyond the disclosed range. The non-working example 2 also suffers

from processability issues in a manner that it cannot be stamped in form of a bar on account of being sticky.
Example 2
Working and Non-Working Examples with respect to the process of
preparation
[0073] The process for preparing translucent soap composition as disclosed in the present disclosure (Example 1) comprises following steps:
a. The solid mass was contacted with the first liquid component to obtain
opaque soap noodle;
b. The at least one second humectant of the second liquid component was
contacted with the soap noodle to obtain a soap mixture;

composition;
d. A second part of sodium silicate was contacted to the translucent soap
mix to obtain a hard translucent soap mix, wherein the second part of
sodium silicate is 25% to 40% with respect to total sodium silicate
content present in the composition;
e. The at least one surfactant was contacted to the hard translucent soap
mix to obtain the final translucent soap composition,
wherein the at least one second humectant was continuously added at a flow rate in a range of 0.3%-0.8% per minute through step (b) to step (e).
[0074] Optional additives can be added along with the second liquid component. The optional additives can be surfactants, pH regulator, preservatives, water-soluble actives, fragrance, colourants, electrolytes, humectants, structurants, chelating agents, and combinations thereof.

As per requirement, certain optional additives can be added after step (e) to complete the process. The process comprises manufacturing steps of extrusion, cutting, and stamping to obtain the translucent soap bar.
The surfactants were added at three different stages during the entire process of preparation of translucent soap composition.
1. Surfactants were added during the stage of soap noodle preparation. Appropriate list of surfactants along with weight percentage ranges have been disclosed in the present disclosure, at this stage the surfactants are added at a temperature in a range of 100°C-180°C
2. Surfactant was added to the hard translucent soap mix. At this stage, the surfactant used was sodium alpha olefin sulfate in a weight percentage in a range of 2-4% with respect to the translucent composition. The surfactant was added in a temperature in a range of 20-50°C
3. Surfactant may be added as an optional additive after the final step. Appropriate list of surfactants have been disclosed in the present disclosure. At this stage, the surfactant can be added in a colder condition.
[0075] Working example A and non-working example B as described in the paragraphs below dictate process relating to preparation of preparation of the translucent soap composition.
[0076] Working example A - The process of preparation of the soap composition as disclosed in example 1 complies to the process as disclosed in the present disclosure. It consists of the following steps:
1. The solid mass was contacted with the first liquid component to obtain opaque soap noodle;
2. Glycerine of the second liquid component was added at the rate of 0.3 to
0.8% /minute to crushed soap noodles to obtain soap mixture;
3. The soap mixture of step (2) was contacted with at least 60% of sodium silicate to obtain soap mix;
4. The soap mix of step (3) was mixed and remaining amount of sodium silicate was added to obtain hardened soap mix;
5. At least one solid surfactant was mixed with the soap mix of step (4) to obtain soap surfactant mass;

6. Optional ingredients were mixed with the soap surfactant mass of step (5) to obtain translucent soap mass; and
7. The translucent soap mass of step (6) was extruded, cut, and stamped to obtain translucent soap. The second liquid component was constantly added through steps 2 - 6, at the rate of 0.3 to 0.8% /minute.
Result obtained: The obtained soap is translucent having a lux value within the range of 150 to 200 obtained from the soap noodle in the range of 10-20. [0077] Non-Working Example B - The process of preparation of the soap composition as disclosed in Example 1 as per the present Non-Working Example B is as follows:
1. The solid mass was contacted with the first liquid component to obtain opaque soap noodle;
2. The total amount of glycerine of the second liquid component immediately
added to crushed soap noodles to obtain soap mixture;
3. The soap mixture of step (2) was contacted with at least half of sodium silicate to obtain soap mix;
4. The soap mix of step (3) was mixed with remaining amount of sodium silicate to obtain hardened soap mix;
5. At least one solid surfactant was mixed with the soap mix of step (4) to obtain soap surfactant mass;
6. Optional ingredients was mixed with the soap surfactant mass of step (5) to obtain soap mass; and
7. The soap mass was of step (6) was extruded, cut, and stamped to obtain soap. Result obtained: The obtained soap composition is not translucent and lux value of the composition does not fall in between the range of 150-200.
[0078] As can be inferred from working example A and non-working example B, in case of working example A, glycerin of the second liquid component is added at a flow rate of 0.3% to 0.8% throughout the process after obtaining opaque soap noodles resulting in a translucent soap composition. Whereas, in case of non-working example B, entire glycerin of the second liquid component is added at a single step immediately after the preparation of opaque soap noodles. Therefore, the soap composition obtained in case of non-working example B is not translucent.

Thus, the criticality of the process as disclosed in the present disclosure is substantiated with the help of the examples A and B as depicted above. The addition of glycerin at a flow rate of 0.3% to 0.8% throughout the process after obtaining soap noodles is therefore required to obtain the translucent soap composition from opaque soap noodles.
[0079] Overall, the example 1 and example 2 asserts the importance of the process for preparing the translucent soap composition as described in the present disclosure as well as the criticality of the weight ratios and percentages of the components as a part of the soap composition. Advantages of the present disclosure
[0080] The present disclosure discloses a process for preparing a translucent soap composition from an opaque soap noodle and also discloses the composition of the translucent soap obtained by the process.
