DESC:The following specification particularly describes and ascertains the nature of this invention and the manner in which it is to be performed:-
TECHNICAL FIELD
The embodiments herein relate to cleansing composition and a method for preparing the same. More particularly, the embodiments relate to cleansing concentrate solution which provides desired viscosity on dilution, thus enhancing the cleansing experience. The embodiments also relate to the reconstituted cleansing composition prepared from the cleansing concentrate solution having the desired viscosity and the method for preparing the same.
BACKGROUND
The demand for cleansing, sanitizing, and cleaning solutions have increased exponentially in the light of the COVID Pandemic. May it be in the form of handwashes, cleansing bath compositions, cleansing detergents or surface cleaners, the demand for production and utilization of cleansing products have also increased substantially across all sectors. Due to the increased demand of such solutions on a regular basis, especially in private homes, hospitals, hospitality industry, public and private enterprises, storage of these products has become an important aspect and all the more challenging. Also, due to the increased quantity of the product the resources and effort of packaging further adds to the cost of the product. Moreover, transport of these products from the manufacturing units to the shelves of businesses and from there to the consumer location has also become a significant cause of cost and cause of excessive carbon emission and pollution and a concern due to sheer increase in their production and demand.
There was therefore a need for solving the problem of storage and transport without compromising on the quality and user experience of the cleansing composition. One approach undertaken to address above problem was to make an anhydrous powder form of the cleansing composition that could be reconstituted at the location of use, thus reducing the burden on storage and transport facilities. Several manufacturers have attempted this solution. However, there were several challenges that made this approach less desirable. First and foremost, when reconstituted with water, these products were unable to provide desired viscosity in the reconstituted form, thus dampening the user experience. Moreover, the challenge of manufacturing, packaging and emptying a powdered form into the container both at manufacturing facilities and at consumer location led to wastage of product and caused the aerosols to escape making them a source of pollutants in the air. Furthermore, potential health hazards due to aerosols was another cause of concern.
Considering the problems and potential environmental and health concerns with aforementioned approach, another approach involving concentrated cleansing solution that can be diluted into a container at the location of use was attempted to overcome the aforementioned issues and to take care of the wastage, health and environmental problems. However, such another approach required a product that can be diluted by the consumer without too much difficulty, with desired viscosity, keeping intact the user experience of the store-bought, ready-to-use liquid cleansing solutions.
The quality of the existing products in the market was noticed to be below average since not many of the existing products managed to provide the viscosity comparable to store-bought, ready-to-use liquid cleansing solutions. The existing products when diluted by consumer either provide a free flowing non viscous solution or a turbid solution which is disagreeable. Some were seen to form lumps in the container making the product inconsistent. Not many products in the market provided a diluted/ reconstituted solution that is desirably viscous, clear, and of the consistency of a store bought ready to use product.
Therefore, there exists a need for a product that obviates the aforementioned drawbacks.

The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
After several trials and experimentations, the optimum composition that would not only provide the optimum viscosity for the concentrate but also provide the desired viscosity when diluted for use was arrived at. Once the right proportion of the key elements were determined several studies were conducted to prove their efficiency in achieving the desired results.
Various parameters were considered to determine the sensory characteristics of the product. For instance, foam ability and viscosity plays an important role for user experience of any cleaning composition. The embodiments of the composition were tested for both foaming profile and viscosity.
Foam Measurement
Given that foaming is one of the important factors that provide the sensory experience for a cleaning product, several experiments for Foam measurements were conducted. The Foam was measured by using the Kitchen blender method. Foam generated by Kitchen blender in medium speed of definite quantity of 5% solution of cleansing composition diluted with standard hardness water. Kitchen blender was run for 60 seconds, and the foam was transferred to a 1000ml measuring cylinder and height is measured in ml and represented as Foam Height.
Since foam ability of cleansing solution is often affected by the hardness of water, the foam ability of the diluted cleansing compositions disclosed in embodiments was measured using Hard water. In one embodiment, 5grams of formulation sample after dilution and 95grams of 600ppm hard water were weighed in a glass beaker and mixed well to become homogeneous liquid.
Weighed test solution liquid was then transferred into medium size kitchen blender jar with liquidizer blade type. The blenders were operated at an input voltage of 230 ± 10 V at the low setting. The blender was run for 60 seconds sharply in medium speed. After 60 seconds, the jar was inverted into 1000ml graduated measuring cylinder and the lather adhering to the jar was scooped out and allowed to drain completely. The lather volume was then measured after levelling off the top surface of the foam. The experiment was carried out at an ambient temperature of 27 ± 2°C. All apparatus and chemicals involved also was maintained at the ambient temperature.
Viscosity Measurement
An important factor that impacts sensory characteristic of a cleansing composition is the viscosity. Viscosity is the measure of a liquid’s resistance to flow under an applied force. Viscosity is measured by Brookfield DV I + Viscometer. This instrument has a rotating spindle attached to a force measuring meter. When the spindle is submerged in the sample, it gives a viscosity reading based on the force required to maintain a specific rotating speed. In one embodiment, 100ml of sample was taken in beaker and incubated in ambient temperature between 27±2°C. Viscosity was measured at standard 20 rpm with LV4 spindle.
Several experiments were conducted to determine the foam height and viscosity profile of the embodiments disclosed here.
A set of experiments were conducted to optimize the composition of embodiments disclosed here in.
Experiment 1: Comparison of property based on change in Non-ionic surfactant:
Three distinct compositions of the cleansing composition concentrate were prepared to understand the effect of change of Non-ionic surfactant on the viscosity, pH, foaming properties and consistency of the composition. The non-ionic surfactants used in these formulations were Laureth 3 (Example 3), Laureth 7 (Example 4) and Alkyl polyglucoside (Example 5). It was observed that the value of viscosity at LV4 50 rpm of formula developed for Example 3 was highest followed by value of viscosity in Example 4 and Example 5 in the decreasing order. It was further observed that adding Laureth 3 in a composition made a synergistic combination with PEG150 DS at 7X dilution. While the formulation developed using Laureth 3 in Example 3 exhibited as a gel type concentrate, formulations in Example 4 and Example 5 exhibited Watery appearance both before and after dilution. A tabular representation of this experiment has been provided in Table 6.

Experiment 5: Effect of change in proportion of Laureth 3 and PEG150 DS on viscosity profile
Six distinct examples of the embodiments were prepared by varying the ratio of Laureth 3 and PEG150DS used in the composition. The ratio of Laureth 3 to PEG150DS was 1:3 in Ex.3, 2:3 in Ex.18 and Ex.19, 1:1 in Ex.19, 2:1 in Ex.20 and 3:1 in Ex.21. While the viscosity of all these were within the desirable range, there was nevertheless a significant change in viscosity that can be attributed to the change in proportion of Laureth 3 and PEG150 Distearate. A tabular representation of this experiment can be found in Table 10. A graphical representation of the comparative viscosity and foam height of the compositions has been provided as Fig 3.
