TECHNICAL FIELD
[001] The subject matter described herein in general relates to cosmetic
compositions, and in particular, relates to personal care compositions.
BACKGROUND OF INVENTION
[002] Cleansing compositions are typically applied to skin and rinsed-off with water. However, the application of cleansing materials to the skin, such as soap or other harsh detergents, removes oils that are naturally present on the surface of the skin thereby resulting in a loss of moisturization, and in extreme cases causes skin irritation and dry skin. Although, in the recent years, mild surfactants are being increasingly used in skin care compositions to clean skin without harming skin by stripping off essential proteins and lipids, these compositions are poor in skin mildness (US 4,673,525).
[003] Yet another approach that is popularly followed is the use of humectants and skin friendly polymers which at the most result in not drying the skin. Therefore, users typically must moisturize their skin in a separate step following cleansing, with the intent that the skin remains moist, for extended periods. Although some dual action cleansing/moisturizing rinse-off products exist, such as those compositions disclosed in US9399007 B2, and EP1051153A1, these products are difficult to formulate, because the cleansing ingredients, in general, tend to be incompatible with the moisturizing ingredients. Further, these products lack the ability to effectively moisturize the skin because the contact time of rinse-off formulations is very less (< 1 min) as opposed to leave-on skin products such as skin care creams and lotions which remain on skin longer.
[004] Therefore, there exists a need for cleansing compositions which are effective skin cleansers, mild on the skin, not cause post-wash dryness, and can also deliver a moisturizing agent to the skin. This would provide users with the convenience of obtaining both a cleansing and a moisturizing benefit from a single product.
SUMMARY OF THE INVENTION
[005] In an aspect of the present invention, there is provided a moisturizing composition comprising a) a cleanser mix; and b) an oil mix, wherein the cleanser mix to the oil mix weight ratio is in the range of 1:0.5 to 1:2.2. [006] In an aspect of the present invention, there is provided a process for preparing a moisturizing composition comprising a) a cleanser mix; and b) an oil mix, wherein the cleanser mix to the oil mix weight ratio is in the range of 1:0.5 to 1:2.2, said process comprising steps of: a) obtaining the cleanser mix; b) obtaining the oil mix; and c) contacting the cleanser mix with the oil mix to obtain the composition.

EXAMPLES
[0064] 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. [0065] As mentioned previously, conventionally used dual action cleansing/moisturizing rinse-off products are difficult to formulate, because the cleansing ingredients, in general, tend to be incompatible with the moisturizing ingredients. Further, these products lack the ability to effectively moisturize the skin because the contact time of rinse-off formulations is very less (< 1 min) as opposed to leave-on skin products such as skin care creams and lotions which remain on skin longer. The compositions of the present disclosure provide excellent skin feel characteristics, without dehydrating the skin or result in loss of skin suppleness, and also provide a level of skin conditioning performance in a
wash and rinse-off product which previously has only been provided by a separate post-cleansing moisturizer.
Example 1
Comparative analysis of compositions for establishing working weight ranges [0066] The moisturizing cleansing composition was obtained via an experimental effort in order to establish a working ratio between the various components. The Tables 1 and 2 below describes the various combinations attempted in order to establish the working weight ranges (provided in weight percentage with respect to the composition).

[0067] Moisturizing cleansing compositions as shown in Tables 1 and 2 were prepared; and their rinsability and post-wash oiliness were evaluated. Rinsability is the ease with which the compositions are rinsed off with water. For this purpose, panelists were asked to apply on face the way they use any face wash and rinse off. The ease of rinsing was assessed by panelists and scores given from 1 to 10, 1 being difficult and 10 being very easy to rinse. Post wash the extent of oiliness perceived by panelists were again rated by them scoring from 1 to 10, 1 being the least oily to 10 being very oily. The results are presented in Figure 1. [0068] From the Figure 1, it can be observed that the score for rinsability was found to be greater than 6 for all the compositions; however, compositions A2, A5, A6, A7, A8 and A10 seemed to outperform the others in terms of rinsability. Further, the oiliness on the skin was assessed after rinsing off the composition. Compositions A2, A5 and A6 showed very little oil on the skin, post-wash, which is indicative of excellent cleansing properties.
[0069] From the combined reading of Tables 1 and 2, and the results presented in Figure 1, it can be inferred that the ratio of cleanser mix: oil mix; and the ratio of mineral oil: petroleum jelly, was critical in determining the cleansing and moisturizing properties of the composition. It was observed that when the cleanser mix to the oil mix weight ratio is in the range of 1:0.5 to 1:2.2, and when the mineral oil: petroleum jelly is in the range of 1:0.03 to 1:0.5, the compositions showed excellent cleansing properties, and enhanced moisturizing property. The compositions A2, A5 and A6 were found to lie within the mentioned ratio ranges. Upon comparison, the compositions A2, A5 and A6 seemed to perform well in all aspects.
Advantages of the present disclosure:
[0070] The present disclosure reveals a composition that can cleanse a wide variety of substances from the skin including, for example, eye-shadow, mascara, make¬up, soil and the like in addition to imparting a moisturizing effect on the skin. Further, the composition provides excellent skin feel characteristics, without dehydrating the skin or result in loss of skin suppleness, and also provide a level of
skin conditioning performance in a wash and rinse-off product which previously has only been provided by a separate post-cleansing moisturizer.
