, Description:FIELD OF INVENTION
[0001] The present disclosure relates to the field of a bubble soap solution. In particular the present disclosure relates to a composition for making a bubble soap solution that yields high bubble density per blow as well as with multiple blows, and process for preparing the same.

BACKGROUND OF THE INVENTION
[0002] Making of soap solution and blowing bubbles has amused children ever since. Blowing bubbles is an interplay between chemistry, physics and art. Blowing bubble can teach many aspects of science to children, especially blowing pressure, wind directions, use of correct type of wand, and art of blowing bubbles. One of the important criteria for a soap solution for making bubbles is that the solution should have sufficient stickiness that can form a film on the wand. The bubbles produced either manually or with the aid of toy gun should displays good luster and shine and they should last longer in the air while travelling. Besides, shine and luster, if the bubbles have fragrance children prefer such soap solution more. Additionally, more the bubbles formed more children find is amusing without having to blow with too much of force or repeatedly. Thus, soap solution needs to include components that fulfill all such criteria.
[0003] There are different types of formulations and processes of making soap solutions known in the art.
[0004] One of the approaches known utilizes sugar and corn syrup, a dishwash detergent and 40 wt% water. Though such formula would make bubble solution for domestic play but not very cost effective for commercial scale production and sale. Another approach requires heating to dissolve the cellulose powder at around 70 degrees Celsius. Heating and cooling increase the process time. Further, the formula utilizes secondary solvent which adds to the raw material cost. Thus, such approach for process of making bubble solution costly.
[0005] However, the approaches known heretofore are however do not provide formulation or process for making soap solution that can provide bubble in desired quantity and attributes.
[0006] For making the bubbles it is necessary that the soap solution stays on the wand. For this reason, appropriate surfactant in sufficient quantity and proportion is used. In order to make more numbers of bubble, formulations use high concentration of surfactant, this makes the solution cost prohibitive. Besides, such soap solution may not have desired attributes of bubbles to make them more enjoyable for children.
[0007] Thus, there remains an unmet need for providing a soap solution formula of appropriate quality that can yield bubbles with desired attributes, high bubble density per blow, with multiple blows and process for producing said soap solution with reduced cost.

It is to be understood that this disclosure is not limited to particular methods, and experimental conditions described, as such methods and conditions may vary.
Example 1
Preparation of bubble soap solution of the present invention
[00072] In water obtained by reverse osmosis (RO water) (500 mL), hydroxyethyl cellulose (Natrosol 250 HHR) (0.46 g) was added while stirring at room temperature. The pH of the solution was raised to pH 8 by dropwise addition of dilute sodium hydroxide solution. To this solution, pre-dissolved aqueous solution EDTA, 2Na (0.05 g in 25 mL RO water) was added at once while stirring continuous. Premix of surfactant system solution (2g of secondary alkyl sulfonate (SAS-60) 2.5g of lauryloxide amine (LOA), and 2g of cocamidopropyl betain, (CAPB) all added to 20.7 RO water) was added at slow stirring. Preservative Phenoxy ethanol (0.3g) was added at once. Food grade purple color and vanilla perfume was added in sufficient quantity. After 30 minutes of mixing a clear viscous liquid was obtained having pH value of 7.2. Viscosity measured by Ford Cup B-4 was 24 sec and density of 1 as measured by density bottle.
[00073] After 24 hours of maturation the bubble solution was able to yield at least 35 bubbles in a single blow, and at least 4 blows can be easily done in a single dip of wand in this solution. Thus, the soap solution yielded more than 100 bubbles in one dip with excellent shine and they lasted minimum 30 seconds in the outdoor environment.
[00074] The formulation thus prepared was subjected stability chamber for four weeks in its selected packaging with wand inserted in it at 75% relative humidity and 35 deg Celsius. The performance of this solution was checked every week for formulation stability, color fading, perfume loss. The product showed no deterioration.
Example 2
Comparative examples
[00075] Formulations of bubble soap solutions in accordance with the present invention as well as comparative formulations were prepared as per the process detailed in Example 1 using the composition in Table 1.
[00076] Below tables demonstrates the effect of variation in formulations on the quality of bubble solution.
[00077] Table 1 shows the effect of formulation variation on the physical properties of the bubble solution.

[00078] It is evident from Table 1 that the formulation comprising surfactant system with SAS-60, LOA and CAPB exhibited unexpected synergism to yield stable formulation with desired viscosity. When the formulation was devoid of either SAS-60, LOA or CAPB, the product was unstable and formation of two layers was observed in the stability run.
[00079] Table 2 illustrates the effect of formulation variation on the performance parameters of the bubble solution.

[00080] From Table 2, it is observed that the hydroxyethyl cellulose (HEC) in defined provides stable matrix to the surfactant combination and yield bubbles with desired performance. Upon increasing the HEC concentration the formulation turn-out to be hazy while reducing the HEC concentration resulted into very thin waterlike solution.
[00081] The findings of Table and Table 2 illustrate the presence of HEC and ternary surfactant system comprising anionic surfactant, non-ionic surfactants and amphoteric surfactant in defined concentrations is essential to provide a stable formulation.
[00082] Overall, the present invention provides a novel and inventive composition and process for preparing soap solutions, which is stable, can yield greater number of bubbles having desired attributes.
[00083] From the foregoing, it will be appreciated that, although specific embodiments of the invention have been described herein merely for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention and should not be construed so as to limit the scope of the invention or the appended claims in any way.
