FIELD OF INVENTION
[001] The present disclosure relates to a personal cleansing composition in general
and in particular to liquid cleansers. There is provided a transparent cleansing
composition and a process to prepare the aforementioned transparent cleansing
5 composition.
BACKGROUND OF THE INVENTION
[002] Cleansing of body, along with following other hygiene-improving practises helps in getting away with visible dirt, as well as germs. To achieve the same, a lot of cleansing compositions are available in the market. In particular, liquid personal
10 cleansing compositions are gaining popularity because of the ease of use and
convenience they offer. These are available in both, transparent as well as opaque versions, of which the transparent ones are more preferred by the end-users, largely for aesthetic reasons. [003] Many of the available transparent liquid cleansing products are associated with
15 certain problems; low transparency, lump formation, crystallization, and discoloration
to name a few. Transparent soaps have aesthetic appeal and are perceived to be milder than the opaque soap compositions. Soap based transparent liquid cleansers which are known in the prior art typically utilize ricinoleic acid soaps to attain transparency. Few other types of liquid soaps known in the art are surfactant based liquid soaps, tallow
20 soap based compositions, and triethanolamine based compositions. However, it has
been found that triethanolamine based soaps cause visible color changes, which is undesired. Reducing agents like alkali metal sulfite, bisulfite and metabisulfite can also be used as discoloration preventing additives in transparent soaps, but these additives are effective only in the presence of citric acid. Moreover, the problem with the
25 reducing agents is that they have a finite solubility in the soap system which leads to
their crystallization, resulting in loss of transparency of the liquid soap composition. [004] Accordingly, there remains a need for an improved soap based composition which is transparent as well as stable.

[008] These and other features, aspects, and advantages of the present subject matter
will be better understood with reference to the following description and appended
claims. This summary is provided to introduce a selection of concepts in a simplified
form. This summary is not intended to identify key features or essential features of the
5 claimed subject matter, nor is it intended to be used to limit the scope of the claimed
subject matter.
DETAILED DESCRIPTION OF THE INVENTION
[009] Those skilled in the art will be aware that the present disclosure is subject to
variations and modifications other than those specifically described. It is to be
10 understood that the present disclosure includes all such variations and modifications.
The disclosure also includes all such steps, features, compositions, and compounds referred to or indicated in this specification, individually or collectively, and any and all combinations of any or more of such steps or features.
Definitions
15 [0010] For convenience, before further description of the present disclosure, certain
terms employed in the specification, and examples are delineated here. These definitions should be read in the light of the remainder of the disclosure and understood as by a person of skill in the art. The terms used herein have the meanings recognized and known to those of skill in the art, however, for convenience and
20 completeness, particular terms and their meanings are set forth below.
[0011] The articles “a”, “an” and “the” are used to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article.
[0012] The terms “comprise” and “comprising” are used in the inclusive, open sense, meaning that additional elements may be included. It is not intended to be construed as
25 “consists of only”.
[0013] Throughout this specification, unless the context requires otherwise the word “comprise”, and variations such as “comprises” and “comprising”, will be understood
4

to imply the inclusion of a stated element or step or group of element or steps but not the exclusion of any other element or step or group of element or steps.
[0014] The term “including” is used to mean “including but not limited to”.
“Including” and “including but not limited to” are used interchangeably.
5 [0015] The terms, ‘transparent’ and ‘translucent’ refer to complete clarity and partial
clarity respectively. Thus, compositions which have been described as ‘transparent’ were clear in appearance, allowed light completely to pass through it as any other transparent object would allow, and one could see through the composition. Contrarily, compositions which have been described as ‘translucent’ were typically characterized
10 by some turbidity, didn’t allow light to completely pass through them, and one could
not see through them with same clarity as was possible in case of transparent compositions.
[0016] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which
15 this disclosure belongs. Although any methods and materials similar or equivalent to
those described herein can be used in the practice or testing of the disclosure, the preferred methods, and materials are now described. All publications mentioned herein are incorporated herein by reference. [0017] The present disclosure is not to be limited in scope by the specific
20 embodiments described herein, which are intended for the purposes of exemplification
only. Functionally-equivalent products, compositions, and methods are clearly within the scope of the disclosure, as described herein.
[0018] Although salts of fatty acids which were used as soaps in the instant disclosure were prepared in-situ from fatty acids and alkali metal hydroxides, commercially
25 available readymade fatty acid salts, i.e. soaps are contemplated to fall within the
scope of the present disclosure.
[0019] As discussed above, known liquid soaps such as triethanolamine based soaps undergo excess colour change during shelf life. Although addition of reducing agents is one of the remedies to this problem, it suffers from its own drawbacks like
5

crystallization of these reducing agents resulting in loss of transparency. To address
the problem as discussed above, the present disclosure provides a cleansing
composition containing a specific combination of C14 fatty acid soap, surfactant,
solubilizer, and humectant. The disclosed composition overcomes the aforementioned
5 drawbacks by preventing crystallization at room and/or at low temperatures and also
the discoloration due to thermal ageing or UV exposure.

15 Example 1
Transparent cleansing compositions having different constituents in varying
amounts
[0050] Various liquid cleansing compositions were prepared by varying the amount of
constituents used. Further, based on the results obtained in terms of the transparency,
20 or the lack thereof, a correlation was established between weight percentages of the
constituents and the effect it has on the transparency. Compositions that exhibited
excellent transparency are described in Tables 1 and 2 below.

[0051] As can be inferred from Tables 1 and 2, all the compositions exhibited
excellent transparency. Based on these results, weight percentage ranges for all
components were arrived at. These ranges have been described in details in the
5 detailed description herein above. Further, viscosities for all the compositions were
also good, in general. On other parameters like lather volume too, these compositions performed well. Lather volume was calculated as follows.2 gm of sample was added to a blender vessel and 98 g of 60 FH water was added subsequently. The mixture was blended for a minute and the resultant lather was collected in a measuring cylinder and
10 its volume recorded.
[0052] These results were further confirmed by recording results for experiments, wherein the weight percentages were varied to fall outside the ranges arrived at based on results obtained for Compositions 1 – 3. Details of the same are provided in Tables 3 – 6 below.

[0053] Data provided in Tables 3 – 6 clearly indicates that, when components were
used in weight percentages outside the ranges determined based on results obtained for
5 Compositions 1 – 3, resulting compositions yielded disappointing results in terms of
transparency. In the discussion hereafter in this paragraph, terms ‘higher’ and ‘lower’
have been used with reference to the weight percentage ranges mentioned in the
detailed description section. When CMEA was used in higher amount (Composition
4), the resulting composition was translucent, with crystals appearing in the
10 composition. Similarly, when compositions completely devoid of CMEA were
prepared, these compositions turned out to be completely opaque (Compositions 5 and 6). Composition 7 which had the humectant in a quantity lower than required, was
37

opaque like the previous two compositions. Further, when attempts were made to prepare compositions containing triethanolamine, it was found that these compositions too were opaque. One such compositions for which details are mentioned above in Table 4 was Composition 8. Composition 9 (Table 5) comprised the solubilizer (PEG 5 40 hydrogenated castor oil) in higher amount, and it was found that this composition too suffered from the problem of translucency. Finally, Composition 10 (Table 6) containing the solubilizer (PEG 40 hydrogenated castor oil) in lower amount was prepared and tested similarly for transparency characteristics. This composition too was translucent with crystallization being observed. 10 [0054] Thus, based on the results presented in Tables 1 - 6, it can be concluded that desired transparency in the liquid composition could be achieved only when the components were used in certain weight percentage ranges. Any deviation from these ranges either resulted in translucency accompanied by crystal formation or outright opacity.
15 Example 2
Preparation of the cleansing composition:
[0055] The composition of the instant disclosure was prepared using the following procedure: (a) fatty acid and non ionic surfactant was weighed and added to the main vessel and heating was started to ensure melting of the components (70-85 ℃); (b)
20 humectant was weighed and added to the mixture from step (a) and heating continued at 70 - 85 ℃ along with stirring; (c) alkali metal salt was weighed and added to the mixture from step (b) under hot conditions (70-85 ℃) with stirring; (d) polymer dispersed in small portion of propylene glycol was then added under hot conditions (70-85 ℃) with stirring; (e) amphoteric surfactant was weigh and added under hot
25 conditions (70-85 ℃) with stirring; and (f) solubilizer was weighed and added around 40-55 ℃ and mixing continued to get a homogenous mixture.
[0056] All examples, working as well as non-working were prepared using the process described in Example 2.
38

[0057] The present disclosure thus provides a soap based transparent liquid cleansing
composition which owes its transparency to presence of the components that constitute
the composition in certain weight percentage ranges. This transparency is achieved
without any compromise on other desired attributes like viscosity and lather volume.
5 [0058] Although the subject matter has been described with reference to specific
embodiments, this description is not meant to be construed in a limiting sense. Various
modifications of the disclosed embodiments, as well as alternate embodiments of the
subject matter, will become apparent to persons skilled in the art upon reference to the
description of the subject matter. It is therefore contemplated that such modifications
10 can be made without departing from the present subject matter as defined.
