FIELD OF INVENTION
[001] The present disclosure broadly relates to field of personal hygiene and
particularly relates to ploddable soap compositions.
BACKGROUND OF INVENTION
[002] Skin dryness is majorly caused due to the kind of soap used by a consumer. Skin dryness associated with soaps is a problem that the soap industry has been grappling with for more than four decades. Various attempts have been made to arrive at soap compositions with high moisturization effect. It has been a continuous
10 struggle to manufacture soaps with enhanced sensory properties and sensitive skin compatibility for personal washing and hygiene. Consumers value a feel of soft skin after cleaning with a soap.
[003] Achieving specific moisturization effect from commonly available ingredients is a challenge that the soap-making industry routinely comes across.
Finding and balancing the workable weight percentage of humectants and total fatty matter (TFM) are generally crucial in achieving ploddable compositions with high moisturization effect. Generally, glycerin is one of the most popularly used humectant that is used in manufacture of soaps. Use of high amount of glycerin in transparent soaps has been known and it is relatively easier to incorporate high
amount of glycerin and similar solvents in transparent soaps. However, it remains a challenge for translucent or opaque, ploddable soap compositions comprising higher TFM.
[004] Further, it remains a challenge to arrive successfully at composition for soaps, especially ploddable soap compositions combined with significantly higher moisture concentrations. This is essentially because higher moisture levels in soap lend better sensorial capabilities to finished bar and hence represents a desirable characteristic.
[005] US6218348B1 discloses a soap bar composition with specific equivalent molar ratios of fatty acid to protic acid salt and specific weight ratio of polyalkylene
glycol and salt of protic acid to free fatty acid. The resulting soap compositions

provide a refreshing sensory experience while retaining more moisture in the skin, producing lower levels of visual dryness and maintaining a stronger protective barrier than ordinary soap.
[006] US6630432B2 discloses a soap bar composition comprising primarily fatty acid soap as cleansing agent and containing salts of alpha-hydroxy acids (e.g., sodium lactate). Sodium lactate is known to have natural moisturizing humectant properties. It describes ploddable soap bars containing a-hydroxy acid produced by mixing 40% to 80% fatty acid soap, 2% to 15% salt of a-hydroxy acid and water with at least 3% of monoglycerate, free fatty acid or mixtures thereof. [007] Thus, the conventionally known plodding and stamping methods for manufacture of opaque soaps severely restricts the amounts of humectants that can be incorporated in a typical plodded soap bar. Despite several advances of extrusion process, there remains a need for a ploddable soaps that can offer a rich sensory experience combined with high moisturization effect, which may be experienced as a combination of a gel and cream effect.

DETAILED DESCRIPTION OF THE INVENTION

[0015] 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
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
[0016] 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
completeness, particular terms and their meanings are set forth below.
[0017] 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.
[0018] 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 "consists of only".
[0019] Throughout this specification, unless the context requires otherwise the word
"comprise", and variations such as "comprises" and "comprising", will be
understood 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.
[0020] The term "including" is used to mean "including but not limited to".
"Including" and "including but not limited to" are used interchangeably.
[0021] For the purposes of the present document, surfactant materials can also be an
emulsifier, the term "surfactant" does not exclude materials which also have
emulsification properties.
[0022] For the purposes of the present disclosure, "soap noodles" refer to a
composition comprising sodium salt of fatty acids ranging from C8-C22 fatty acids,
and combinations thereof, it further comprises glycerin in an amount ranging from
6% to 10%, and further comprise about 2% to 5 % surfactant. The surfactant used

can be any surfactant known to be used in the soap formulation. Total Fatty Matter (TFM) refers to the sodium salt of fatty acids ranging from C8-C22 fatty acids, and combinations thereof in the soap noodles. Moisture refers to the overall water content present in the ploddable soap composition of the present disclosure. [0023] Ploddable soap composition refers to the soap composition that is obtained after mixing all the necessary components as disclosed in the present disclosure. The composition thus obtained is further processed (including steps of extruding, plodding, and stamping), to obtain a plodded soap.
[0024] Ratios, concentrations, amounts, and other numerical data may be presented herein in a range format. It is to be understood that such range format is used merely for convenience and brevity and should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, TFM is having a weight percentage in a range of 50%-65% by weight with respect to the composition should be interpreted to include not only the explicitly recited limits of 50%-65% by weight, but also to include sub-ranges, such as 55%-60% by weight, 55%-65% by weight, and so forth, as well as individual amounts, including fractional amounts, within the specified ranges, such as 52% by weight, 59% by weight, 62% by weight, for example.
[0025] Soap compositions are characterized by a specific TFM range. The gel and cream effect diminish as the amount of TFM goes on increasing beyond a specific threshold. The conditioning agents present in the composition not only enhance the moisturizing effect of humectants such as glycerin but also contribute to the gel and cream texture of the soap composition.
[0026] Although there are hydrating soap compositions known in the art, but the high humectant such as high glycerin content comprising soap compositions and soap bars tend to be transparent, whereas ploddable soap compositions having high moisture content and prepared from opaque soap noodles are not known. It is routine and relatively simple to incorporate high amounts of humectants such as glycerin and similar solvents into transparent soap compositions. However, the

conventionally known plodding and stamping methods for manufacture of opaque soaps severely hampers the amounts of humectants that can be incorporated in a typical plodded soap bar. Thus, it remains a problem in the art to balance TFM levels in order to manufacture ploddable soap composition, which tend to be opaque with high humectant and hence, moisture levels so as to achieve soaps with rich sensory experience combined with high moisturization effect, to overcome the issues associated with skin dryness and sensitive skin. More so ever, achieving such a ploddable soap composition with desired high moisturization and a combination of gel and cream effect involves skilled intervention, experimentation and is not obvious to a skilled mind.
[0027] The present disclosure discloses a ploddable soap composition comprising a moisture content having a weight percentage in a range of 15% to 18% by weight with respect to the composition. The present disclosure discloses a ploddable soap composition comprising total fatty matter (TFM); at least one humectant; at least one conditioning agent; wherein the TFM is derived from soap noodles selected from a group consisting of sodium salt of C8-C22 fatty acid, the TFM to the at least one humectant has a weight-by-weight (w/w) ratio in a range of 3:1:: 10.5:1, and the TFM to the moisture content has a weight ratio in a range of 2.7:1 ::4.3:1. The present disclosure also provides a novel method of preparation of said ploddable soap composition.
[0028] Another technical problem associated with high use of humectants in ploddable soap compositions is that these compositions are prone to cracking. Further, these compositions also exhibit high mush.
[0029] The present disclosure addresses the aforementioned problems in the art by incorporating specific amounts of silicate based structurants. The present disclosure discloses a ploddable soap composition comprising total fatty matter (TFM); at least one humectant; at least one conditioning agent; at least one silicate based structurant; at least one optical brightener; at least one coloring agent; and at least one surfactant; and moisture content having a weight percentage in a range of 15% to 18% by weight with respect to the composition; wherein the TFM to the at least one humectant has a weight-by-weight (w/w) ratio in a range of 3:1:: 10.5:1. The present disclosure

provides ploddable soap compositions of that neither show cracks nor exhibit higher amount of mush.
[0030] 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 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.

(8) In a separate vessel, BHT (butylated hydroxytoluene) an antioxidant was first completely dissolved in the fragrance followed by dissolving the conditioning agent (silicone quaternium-18 (and) trideceth-6 (and) deceth-7 (and) cocamidopropyl betaine (and) dipropylene glycol) in an amount ranging from 0.025 to 0.2% to the above fragrance mixture.
(9) The above fragrance mixture was optionally mixed with another round of
additives as required.

(10) After completion of the combination of steps in point (8), the fragrance mixture
was added into the mixer containing the fifth mixture to form the ploddable soap
composition.
The ploddable soap composition as obtained can be further processed for obtaining
plodded soap having desirable qualities.
Example 2
[0064] Working and Non-Working Examples
[0065] The present example provides the working and non-working (NW)
examples of the soap composition of the present disclosure as demonstrated in Table
1 below.
Table 1

[0066] Referring to above Table 1, the compositions were evaluated based on the Panel data and also on the feasibility of producing ploddable soap composition. Working examples 1 and 2 as shown above, have the components within the acceptable weight percentage ranges, hence, they were observed to produce desired texture and sensorial properties and comprised of the requisite moisture content. With respect to the non-working example 1, NW1, the conditioning agent is out of range, glycerin is out of range, sodium silicate is out of range, surfactant is also out of range, further moisture is also out of range, therefore the composition did not yield the desired effect. With respect to the non-working example 2, NW2, glycerin is present in much higher weight percentage (20%) and as a result, the soap mass could not be processed to form ploddable soap bars. With respect to the non-working examples 3-5, NW3, NW4 and NW5, respectively, the TFM is outside the range, thus, though the soap bars could be formed, they did not have gel and cream effect, as desired, and were devoid of the special aesthetic effect i.e., the desired sensory effect was not present and also failed in terms of lather, and foam formation as desired. Example 3
[0067] Comparative data of the present disclosure with respect to the products in market
[0068] The present example provides the data demonstrating the sensorial features as experienced by a panel as shown in Table 2 below.
Table 2

[0069] A study was undertaken to estimate the moisturization effect of the soap composition of the present disclosure. The moisturization effect was measured by a skin moisture sensor (make: Moist Sense II). The study was conducted in 3 different stages to capture the moisture difference.
[0070] Specific skin area was identified with predetermined surface area of about 3x3cm. Moisturization value for the chosen skin area was measured using the skin moisture sensor and the values were recorded before any water or soap treatment of the skin. (Baseline).
[0071] After this, the chosen skin area of the participants was treated with only water and again the moisturization values were recorded. Specifically, base line is moisturization level of skin as such, water treated is when skin is treated with water without any cleansing agent, this is like placebo and the post-product application is after skin is treated with soap composition of the present invention [0072] Post-water treatment, the chosen skin areas of the participants was washed using soap composition of the present disclosure, and again the values were recorded. [0073] Same methodology was followed for all the test samples which included two market products (MP1 which is an opaque soap bar obtained by plodding) and (MP2 which is a transparent soap bar obtained by cast route) along with sample from the present disclosure (P). The sample "P" refers to the Working Example 1 of Table 1. Figure 1 corelates the observation on moisture difference as explained in the present Example.

[0074] It was found that the net moisturization effect measured as the difference between the moisturization values post product application and moisturization values obtained during base line treatment, was markedly better for product of the present application when compared with market product 1 and market product 2. [0075] It is therefore concluded that the soap composition of the present disclosure not only provided better moisturization effect when compared with normal opaque bar obtained by plodding route but it also provided enhanced moisturization effect as compared to the transparent soap prepared by cast route.
Example 4
[0076] Panel evaluation for Skin Feel for plodded soap obtained from the ploddable soap composition of the present disclosure with and without the conditioning agent
[0077] The present example provides the panel data demonstrating the skin feel as experienced by a panel as shown in Table 3 below. The conditioning agent used in the present composition is silicone quaternium-18 (and) trideceth-6 (and) deceth-7 (and) cocamidopropyl betaine (and) dipropylene glycol

[0078] Higher the number as indicated in the Table 3 above, better the skin feeling experienced by the panelists. Overall, the panelists preferred the plodded soap with the conditioning agent as disclosed in the present disclosure.
Example 5
[0079] Panel evaluation for Quality of Lather for plodded soap obtained from the ploddable soap composition of the present disclosure against ordinary Opaque Soap
[0080] The present example provides the panel data demonstrating the quality of lather as experienced by a panel as shown in Table 4 below.

■
[0081] Higher the number as indicated in the Table 4 above, creamier the lather as experienced by the panelists. Overall, the panelists preferred the plodded soap with the conditioning agent as disclosed in the present disclosure over the ordinary opaque soap.
[0082] Figure 2 refers to the density difference between the cast (PI) and plod (P2) forms of the ploddable soap composition of Working Example 1 of Table 1 compared to the market products (MP1, MP2 and MP3). It can be appreciated that the density difference is not much between the cast and plod, but it is much lower than the market products.
