FIELD OF INVENTION
[001] The present disclosure relates to the field of cosmetics, in general, and a moisturizing cosmetic in particular. There is provided a moisturizing formulation primarily comprising a combination of caesalpinia spinosa gum and aluminium starch octenylsuccinate, and a process for the preparation of this formulation.
BACKGROUND OF THE INVENTION
[002] Cosmetics constitute a big pie of the fast moving consumer goods (FMCG) segment of products. Skin care creams/lotions; an important subclass of cosmetics, are much in demand because of the protection they offer against harm to the skin caused by various factors like pollution and exposure to sun. Moisturizing cosmetics are a class of cosmetics used for rejuvenating over-dried or dehydrated skin by retaining the inherent moisture. Over-drying and dehydration of the skin is a common problem which may be due to environmental factors, skin conditions, lower concentration water in skin layer and the like. It is known that dehydrated skin is typically linked with poor barrier function thereby reducing protection from environment, microorganisms, toxins, and the like. Further, the dehydrated skin makes the make-up very hard to apply evenly. There are a number of moisturizing formulations available in the market. Most of these moisturizers though, are either day or night moisturizers which are used to provide light or heavy deep moisturization depending upon the requirements, and are generally available as lotions and creams. However, some of the existing formulations suffer from disadvantages such as short-term hydration, oily residue post application, and being abrasive on skin.
[003] There are moisturizing formulations known in the prior art and one such formulation disclosed in US626496 provides an improved skin care composition having enhanced skin hydration, moisturizing, conditioning, and cosmetically acceptable tactile properties. The composition includes skin hydration system comprising glycerine and plant-derived oil, petroleum or mineral oil, a di-lower alkyl

di-higher alkyl ammonium emulsifier, a fatty alcohol, a fatty ester emollient, and
water.
[004] Another moisturizing formulation disclosed in US201440303229 provides a
less irritating skin moisturizing composition comprising at least one natural
moisturizing factor, butyrospermum parkii, at least one silicone, and pantheon,
formulated into a topically applicable, pharmaceutically acceptable medium therefore.
[005] The aforementioned moisturizing formulations disclosed in the prior art suffer
with disadvantages such as short-term hydration, oily residue post application, being
non-gentle on skin, and causing irritation to sensitive skin due to presence of harsh
ingredients.
[006] In view of the aforementioned limitations of the prior art methods, a better
formulation of moisturizing cosmetic is much needed.

EXAMPLES
[0061] 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 vary. Example 1: Efficacy Study: Agar Plate Method
[0062] Initial experiments were first carried out to test the effectiveness of formulation comprising caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum and aluminum starch octenylsuccinate in retaining moisture, vis-a-vis moisture retention achieved using the individual components of the formulation. As a control, placebo was also tested. Base formulation without moisturizing actives/agents was used as a placebo for the purpose of these experiments. Placeboes are substances which are known not exhibit the effect for which they are being tested. Use of a placebo helps establish the fact conclusively that the effect exhibited by the tested substance/formulation being evaluated, is a specific property of that substance/formulation, and that the same property is not possessed by any serendipitously chosen substance/formulation. In context of the present disclosure, the

placebo is known to not exhibit any moisture retention effect. Thus the results obtained using a placebo can be used as a standard against which the results yielded by the formulation of present disclosure can be evaluated. The experiments were carried out using Agar as a substrate. Its weight before and after application of the test substance/formulation/placebo was measured and the difference in final and initial weight was taken as an indication of the extent of moisture loss. The results are summarized in Table 1 below.

As can be seen from the data in Table 1, individually caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum and aluminum starch octenylsuccinate did not exhibit drastically superior results compared to the placebo. However, the combination

of caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum and aluminum
starch octenylsuccinate yielded startlingly better results as compared to both, the
placebo as well as the individual components.
[0063] It can be seen from Table 1 that the weight loss difference was observed to be
very less for finished product compared to placebo, and the moisturizing agents
aluminum starch octenyl succinate (0.5%) and caesalpinia spinosa gum (1%) when
used in isolation. The order of hydration was found to be: finished product> with 1%
caesalpinia spinosa >with 0.5% aluminum starch octenyl succinate >Placebo.
[0064] Hence, based on the data in Table 1, it can be concluded that a formulation
comprising aluminum starch octenyl succinate (0.5%) and caesalpinia spinosa gum
(1%>) gives synergistic results when tested for the ability to retain moisture.
Example 2: Effect of variation in weight ratio of aluminum starch
octenylsuccinate to caesalpinia spinosa gum and hydrolysed caesalpinia spinosa
gum
[0065] Further experiments were carried out to check what range of weight ratios
between aluminium starch octenylsuccinate and caesalpinia spinosa gum and
hydrolysed caesalpinia spinosa gum yielded similar results as the ones obtained for the
formulation described in Table 1. The details of various formulations that were tested
are summarized in Tables 2 and 3 below.

[0066] Formulations described in Table 2 yielded similar results for moisture retention as those for the formulation in Table 1. The detailed results are provided in Tables 4-7. It can be seen from the data contained in Tables 4-7 that all formulations yielded superior results compared to experiments, wherein components of the formulation were used in same amount but individually. Table 3 shows formulations prepared by making further variations in the weight ratios. The differentiating factor though, between formulations of Table 2 and Table 3 is that in Table 3, all formulations have caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum in lower quantities than aluminium starch octenylsuccinate. In case of formulations of Table 3, lump formation was observed in the final formulation, which is undesirable. Thus, based on the data provided in Tables 2 and 3, it was concluded that to obtain formulation which had all other properties sought in a moisturizing formulation, in addition to its moisture retention capacity, weight percentage of caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum had to be higher than that of aluminium starch octenylsuccinate, and the ratio of octenylsuccinate to caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum had to be in the range of 1:1.1 — 1:4.

Example 3: Process for the preparation of formulation:
Step I. In the first step, glycerin, propylene glycol, EDTA, carbomer, acrylates/Cio-C3o alkyl acrylates and xanthan gum were mixed while stirring at 600-900 rpm, with water at a temperature in the range of 75-85 °C to obtain an aqueous phase.
Step II. Capric/caprylic triglyceride, cetyl alcohol, glyceride, cetyl alcohol, glyceryl stearate (and) PEG-100 stearate, polymethylsilsesquioxane, PPG-15 stearyl ether, isopropyl palmitate, and cetearyl alcohol (and) ceteareth-20 were contacted at a temperature in the range of 80-85 °C to obtain an oil phase.
Step III. Further, the oil phase was homogenized with the aqueous phase to obtain an emulsion by stirring at a speed of 2800 rpm. This was followed by addition of triethanolamine to the emulsion.
Step IV. A premix of aluminum starch octenylsuccinate (0.5% - 1.00%) and caesalpinia spinosa gum (0.5%-2.00%) was then added to the emulsion above at a temperature in the range of 42-48 °C, at mixing speed of 20 - 30 rpm.
Step V. Finally, preservatives phenoxyethanol, methylparaben, propyl paraben, methylisothiazolinone (and) phenoxyethanol, butylated hydroxytoluene (BHT) and fragrance were mixed to obtain a smooth cosmetic composition which was free of lumps.
Table 8 below describes the complete formulation along with the acceptable weight percentage ranges for all the components.

Example 4: Panel Study
I) Comparison of present product with placebo
[0067] In addition to the agar plate method for determining moisture retention capacity, panel analysis was also carried out to collect data on how people perceive the formulation in terms of the moisturization it provides. Accordingly, a panel of ten volunteers was constituted. All panellists were asked to use the placebo and report their views on how moisturized their skin felt on application of the placebo. Panellists were provided only the test formulations and were not informed that it was a placebo. Similar procedure was then asked to be carried out using the formulation of the present disclosure. The data are summarized in Table 9 below. It can be inferred from the data that almost all panellists rated the formulation of instant disclosure better than the placebo.

II) Aluminum starch octenylsuccinate alone Vs. caesalpinia spinosa gum alone
Similar panel studies were carried out to find out how the panellists rate the components of formulation when used individually. Accordingly, aluminium starch octenylsuccinate and caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum were subjected individually to panel analysis. The data are summarized in Table 10 below. Panellist's ratings for aluminium starch octenylsuccinate and caesalpinia spinosa gum and hydrolysed caesalpinia spinosa gum when applied individually were similar to how they rated the placebo. This makes it amply clear that even in terms of user perception, the formulation was far superior to the individual components.

[0068] The present disclosure thus provides a formulation of a moisturizing cosmetic, comprising of a combination of moisturizing agents to provide a high moisturizing effect. The formulation of present invention scores over the prior art formulations with reference to higher hydration/moisture value.
[0069] 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.
