FILED OF INVENTION
[001] The present disclosure relates to the field of liquid cleansing formulations suitable for use in personal care applications. In general, the present disclosure provides a process for preparation of stable cleansing formulation, and in particular a shampoo formulation free of precipitate. BACKGROUND OF INVENTION
[002] Cleansing products play an essential role in our daily lives. By safely and effectively removing soil, germs and other contaminants, they help us to stay healthy. Hair care products constitute an important category of cleansing products. Analyzing and knowing hair needs is of particular importance to keep it healthy. Hair cleansing is somewhat different from cleansing other body parts because of vulnerability of hair to entanglement. To avoid this problem, process of hair care thus involves conditioning, along with washing. To cater to these needs, health care and cosmetic industry has come up with a number of products; some purely shampoos, some purely conditioners, and some a combination of both. [003] However, preparation processes of all these hair care formulations (shampoos, conditioners, and combinations thereof) present a few difficulties. The primary ingredient of all shampoo (hair cleansing) formulations is anionic surfactant responsible for cleansing action and lathering properties. These surfactants play a big role in determining hair's condition after shampooing. Generally, products comprising conditioners along with shampoo also have quaternary ammonium salts and these quaternary salts are incompatible with the anionic surfactant used in shampoo formulation. This incompatibility can be attributed to a possible formation of salt, resulting in precipitation of the conditioning active. Also, use of combination of various surfactants and pH adjustment using alkali raises the viscosity of the formulation drastically. [004] Shampoo formulations are supposed to be excellent cleansers and should get rinsed easily from the hair without any issue of remnants being left behind. It is also expected that surfactants do not precipitate onto hair or in hard water, nor should they leave a residual sticky or tacky feel on to the hair surface.

[005] Therefore, a process for preparation of hair care formulations, which is not marred by problems like precipitation and excessive viscosity build-up, and which results in a product which remains stable without any in-use precipitation, until successful use by the consumers is much required.

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 shampoo formulation:
[0058] The present disclosure focusses on adjusting process of preparation of the shampoo formulation, so as to achieve precipitate free process along with desired viscosity. After various preliminary experimentation the following process comprising of the components as provided in Table 1, a stable shampoo formulation (A) was achieved, which had a desired viscosity and no precipitate formation was observed during the process of preparation.
[0059] The stable shampoo formulation was prepared as follows: Water having temperature in the range of 75 - 80 °C was charged into a mixer. Sodium laureth sulphate (SLES), was added to it and homogenized while temperature was maintained in the range of 75 - 80 °C to obtain a premix-1. After complete homogenization, vacuum was applied in the premix-1 for a time period in the range of 20 - 25 minutes to obtain a premix-2. Further, CMEA, PPG-3 benzyl ether myristate, EGDS, cetyl alcohol, and a dilute solution of EDTA were added to the premix-2 to obtain a a premix-3, while maintaining the temperature of 75 - 80 °C. Furthermore, a mixture of cocoglucoside and glyceryl oleate was prepared

separately by dissolving in water having a temperature in the range of 75 - 80 °C and added to the a premix-3 and the contents were then circulated through in-line homogenizer to obtain a premix-4.
[0060] Water was added in a separate container at a temperature in the range of 25 - 30 °C. To this water in the container orthophosphoric acid was added and further addition of carbomer was carried out using an overhead stirrer in a time period of few minutes. Any lumps formed were dispersed and the contents of the container were added to the premix-4 and contents were homogenized during addition using in-line homogenizer to obtain a premix-5.
[0061] Again, water was taken in a separate container having a temperature in the range of 25 - 30 °C and free flowing polyquaternium -10 (PQ-10) was added to it to obtain a premix-6. Moreover, methylchloroisothiazolinone, methylisothiazolinone and guar hydroxypropyltrimonium chloride were added to the premix-6 while homogenizing. After complete addition, homogenizer was stopped and then CAPB was added to the premix-6 to obtain a first mixture. Further, to the first mixture, a solution of sodium hydroxide, dimethicone (and) cocoamidopropyl betaine, bis-isobutyl PEG/PPG-20/35/amodimethicone copolymer (and) cetyl ethylhexanoate (and) polysorbate 80 (and) butylene glycol, was added to the container to obtain a second mixture, and finally, flow rate of second mixture was adjusted either by adding 1:3 salt solution or sodium xylene sulfonate solution while keeping the temperature in the range of 75 - 80 °C to obtain the cleansing formulation (shampoo) exhibiting desired properties.

Non-working process of preparation:
[0063] Before arriving at the process of the instant disclosure (as described in
Example 1), multiple experiments were carried out to obtain the formulation with
desired properties. The discussion that follows hereafter in Example 2 describes
problems encountered in these experiments, before the process of Example 1 was
arrived at. Issues with viscosity build were observed in the formulations prepared.
To overcome this issue and precipitate formation, sodium xylene sulfonate was
used, . But, with this formulation was found to contain precipitate. Accordingly to
overcome the precipitation/curdling issues certain modifications in the process for
preparation of a cleansing composition (shampoo) were tried.
[0064] Parameter that was found to be critical for the process of preparation
cleansing composition (shampoo) was the addition of hydrotrope, post adjustment
of pH with an alkali. Addition of hydrotrope, post the pH adjustment resulted in a
precipitate free process of preparation of cleansing composition besides the desired
viscosity.
[0065] However, any change in the sequence resulted into precipitate formation
leading into an unstable product.
[0066] In order to ascertain the efficacy of the method of the instant disclosure, an
identical composition was prepared wherein the components were in the working
range as mentioned in Table 1, by deviating from the manner of addition of the
hydrotrope. It was found that when sodium xylene sulphonate was mixed with
sodium hydroxide and then added to the formulation, the formulation precipitated
thereby making product non-acceptable.
[0067] Overall, based on the disclosures above, it can be appreciated that critical
elements of the process of preparation of a cleansing composition are based on
sequence of addition of sodium hydroxide and hydrotrope (sodium xylene
sulfonate), so as to achieve a precipitate free cleansing composition exhibiting
desired viscosity. The process of the instant disclosure is advantageous for the
reason that it achieves precipitate free formulation.
[0068] 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 can be made without departing from the present subject matter as defined.
