FIELD OF INVENTION
[001] The present disclosure relates to the field of hygiene in general and personal cleansing goods in particular. The present disclosure provides a stable cleansing formulation and a process for its preparation.
BACKGROUND OF THE INVENTION
[002] Personal cleansing formulations include soaps, shower gel, body washes, face washes, cleansing milk and hand washes. All the cleansing products attain their cleansing effect either from soaps or surfactants or their combinations. Using ordinary soaps and cleanser can dry the skin and sometimes could also harm the skin. Soap based formulations are known to give quick rinse feel on skin but often result in skin dryness and irritation. In general, the soap based formulations possess good rinsability but the pH is high, around 9.5-10.5, affecting the natural balance of skin. The problem can be solved by replacing soaps with synthetic detergent based formulations in order to provide lower pH and improved mildness.
[003] It is well known that detergent based cleansing formulations consist of surfactants such as sodium lauryl ether sulphate (SLES) which effectively lower the pH, and are often found to be harsh on skin and have rinsability issues. Another commonly used surfactant, generally in liquid cleansing products is sodium cocoyl isethionate (SCI) which is known to be very effective in terms of lowering the pH, but it fails to exhibit soap like rinsability.
[004] In view of limitations in the existing soap based or surfactant based cleansing products, it is desirable to have a formulation which is preliminarily soap based and stable at lower pH, but does not result in post-wash dryness.

EXAMPLES
[0054] 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. Example 1
Process for the preparation of stable cleansing formulation: The stable cleansing formulation prepared as follows:
[0055] Zinc acetate, at least one fatty acid, and propylene glycol were mixed at a temperature in the range of 65 °C to 75 °C to obtain the homogeneous mixture; (b) octyl methoxy cinnamate was then added to the homogeneous mixture and mixed at a temperature in the range of 50 °C to 60°C for a period in the range of 2-5 minutes to obtain the first mixture; (c) further, potassium hydroxide solution was added dropwise to the first mixture to obtain second mixture comprising of in-situ generated metal oxide composite.; (d) at least one surfactant was further added to the second mixture at a temperature in the range of 50 °C to 60°C for a period in the range of 10 -

15 minutes to obtain the third mixture; (e) corn starch and xanthan gum were dispersed in PEG 400 and glycerin to obtain a fourth mixture; (f) fourth mixture was then added to the third mixture, at a temperature in the range of 50 to 60°C under homogenization for a period of 15-20 minutes, followed by optionally contacting with at least one emulsifier at a temperature in the range of 50 °C to 60°C for a period in the range of 10-15 minutes, to obtain the fifth mixture; (g) further, water was added to the fifth mixture at a temperature in the range of 50 °C to 60°C for a period in the range of 10-15 minutes, followed by optionally contacting with at least one active ingredient selected from the group consisting of anti-acne agent, skin lightening agent, moisturizing agent, antioxidant, and combinations thereof, at a temperature in the range of 30 to 40°C for a period in the range of 2-5 minutes to obtain a stable cleansing formulation. Example 2
Study of the various formulations prepared:
[0056] Various working formulations A, B, C, D, E, F, G, and H were prepared following the process as discussed in example 1.

[0057] The observation drawn for the formulations of Table 1 was that, all the formulations (A-H) containing UV absorbers which is stable at a pH of about 8.5 provides thick glossy creamy texture and creamy foam. For all the formulations mentioned in Table 1, ratio of xanthan gum to starch was in the range of 0.1:1-0.15:1. For all the formulations, no post-wash dryness was observed.
Example 3
Formulations without starch:
[0058] To study what effect absence of starch, i.e., corn starch can have on the
formulation, experimentation was done, wherein starch was not added (formulation I
and J), while preparing the formulation, and the results of those experiments are
tabulated in Table 2.
[0059] It was observed that, phase separation was occurred, both at room temperature
and higher temperature. Thus the cleansing formulation was not found to be stable,

Formulations without xanthan gum:
[0061] Similar experiments were carried out to find out if absence of xanthan gum too
has an adverse effect on the quality of formulation. Formulations K and L from Table
2 clearly indicated that when xanthan gum was not added to the formulation, although
no phase separation was observed, viscosity drop at room temperature was evident.
Such formulations fail the likability test and are typically not preferred by the
consumers.
Example 4
Formulation without xanthan gum and starch:
[0062] To establish the effect of the absence of the essential components on the
formulation, another experiment was carried out, wherein both xanthan gum and starch
were kept absent as exemplified in Formulation M of Table 2. The result of this
experiment was that, although the formulation was stable at higher temperatures of
about 50 °C to 60 °C, phase separation was observed at room temperature over a
period of time.
Example 5:
Formulations without decyl glucoside
[0063] Table 3 tabulates the formulations (N to T) prepared without the addition of
decyl glucoside. A general observation for these formulations was that phase
separation was observed at room temperature after a period of one month, suggesting
that decyl glucoside was an essential component for the preparation of cleansing
formulation.

Formulations with variation in the amount of fatty acids:
[0064] Table 4 provides formulation wherein the variations were done with respect to the weight percentages of the fatty acid. Formulation U comprised of fatty acids below 15%, whereas formulation V had fatty acids above 25 %. This variation in the weight percentage of fatty acids, besides, less foam led to the phase separation in the final formulation. Therefore, these cleansing formulations were concluded to be not stable. [0065] Fatty acid weight percentage greater than 25% as exemplified in example V, led to formation of lump and could not be processed further. [0066] Table 4

[0058] The average value often panellists was considered for comparison between the formulations. Formulations C, D and E were subjected to evaluation by panelist and were garnered highest ratings from the test panel with respect to moisturization and post was dryness sensorial. In the sensorial assessment the panellists were subjected to the application of the cleansing formulation on their forearm and wash with water. Panelists were asked to rate immediately as well as after 5minutes and 10 minutes of application of the products to rate in 1 to 10 scale on the skin moisturization, and less post-wash dryness. The cleansing formulation C, D and E indicated more moisturization and less post-wash dryness, as the average score rated by panelist for moisturization and post wash dryness was consistently high across the panel, i.e., an average score of 9 was provided
[0067] Overall the present disclosure provides us with a soap based cleansing
formulation containing UV absorbers which is stable at a pH of about 8.5 and provides
thick glossy creamy texture and creamy foam. Further, the formulation also doesn't
cause any post-wash dryness.
