Specification

FIELD OF INVENTION
[001] The present disclosure broadly relates to field of personal hygiene and particularly relates to a cleansing composition.
BACKGROUND OF INVENTION
[002] Polymers, and silicones are indispensable ingredients that are commonly found in all the cleansing formulations known in the art. Polymers represent the second largest class of ingredients in cosmetics and personal care products. The synthetic polymers are widely used in preparation of cosmetic formulations under many categorises, namely: thickening and gelling polymers, conditioning polymers, fixative polymers, and silicones. Their use is popular because of the aesthetic quality they impart to the product and partly because the formulations are easy to prepare using these ingredients.
[003] The drawbacks associated with the use of such polymers are numerous. Environment is the worst-affected due to the presence of such synthetic polymers in the water bodies. One of the prime factors for the associated dangers with the synthetic polymers is that they are non-biodegradable and remain as a persistent-pollutant in various water bodies. Carbomer and sodium polyacrylate are widely used polymers during the manufacture of cosmetics. Carbomer act as thickening agents and control the viscosity flow in the cosmetic products. The manufacturing process of carbomer produces certain contaminating elements which are carcinogenic. Similarly, sodium polyacrylate has also been reported to be contaminated with certain toxic ingredients during processing. Also, the presence of large amount of alcohols, silicones, and polymers are associated with known risks to the skin. Presence of alcohols tend to cause dryness and irritation to the skin which is not preferred and not associated with the ideal sensorial expectation of a cosmetic formulation.
[004] Apart from the environmental and health hazards that are caused by the use of synthetic polymers, they are also not preferred while manufacturing liquid rinse-off preparations. The reason is partly because they lead to increase in

manufacturing cost. The other important factor is that the use of synthetic polymers interferes with the transparency of the formulation, leading to poor sensorial of the formulation. Thus, a cost-effective, transparent formulation possessing acceptable sensorial feature, and essentially free of silicones, synthetic polymers, and alcohol is highly sought after.
[005] WO2001019946A1 discloses a shower gel formulation having a clear appearance is described which suspends insoluble particles, water insoluble liquids or bubbles and contains an acrylate copolymer, an anionic surfactant, a cationic polymer and, optionally, an amphoteric surfactant. The method of use of the clear shower gel is also described.
[006] US4278570A discloses a skin cleanser formulation, which is one of four components used in a cosmetic regime, is disclosed. Applying the regime to the skin increases epidermal cell turnover without skin irritation. The other three components used in the regime are a cream, a lotion, and a tonic.

[0060] The working and non-working examples as depicted herein asserts the
criticality of the weight percentages and weight ratios of surfactants, and oils as
disclosed in the present disclosure.
EXAMPLES
Example 1
Working and Non-working examples of the formulation
[0061] Different types of working and non-working examples have been depicted
in Table 1. The Table 1 has been represented in three parts namely Table 1A, Table
IB, and Table 1C.

[0062] The Table 1 A, IB, and 1C depicts examples 1 to 23. The examples 1 to 14, and examples 21 to 23 represent non-working examples. Whereas, examples 15 to 20 represent working examples. The working examples depict the presence of surfactants, and oils within the working ranges.
[0063] The tables depict: (a) anionic surfactant - sodium cocoyl methyl taurate, sodium lauryl ether sulfate, disodium cocoyl glutamate, disodium laureth sulfosuccinate, sodium lauryl sarcosinate; (b) non-ionic surfactant - cocamide monoethanolamine (CMEA), PEG-7 glyceryl cocoate, polysorbate 20, lauryl glucoside, decyl glucoside, PEG 40 hydrogenated castor oil, linoleamidopropyl PG-dimonium chloride phosphate; (c) amphoteric surfactant - cocamidopropyl betaine (CAPB); (d) at least one oil - mineral oil, jojoba oil, sunflower oil, and isopropyl myristate; and (e) at least one humectant -glycerine, sorbitol, PEG 400.
The working ranges as disclosed in the present disclosure:
[0064] (a) at least one anionic surfactant has a weight percentage in a range of 4-8% with respect to the composition; (b) the at least non-ionic surfactant has a weight percentage in a range of 5-18% with respect to the composition; (c) at least amphoteric surfactant has a weight percentage in a range of 2-6% with respect to

the composition; (d) at least one oil has a weight percentage in range of 0.5-5% with respect to the composition; and (e) at least one humectant has a weight percentage in a range of 0. l%-7% with respect to the composition. [0065] In light of the same, the examples were categorized into working and non-working examples. The Table 2 depicts the sensorial features of the examples as

[0066] Referring to Table 1A, IB, 1C and 2, it can be appreciated that the non-working examples are considered to be unsuitable because of the presence of alcohol, silicone polymer, or polyacrylate. Also, certain non-working examples like NW2, and NW23 are unsuitable because of the absence of oil as an ingredient. Also, with respect to the sensorial (Table 2), NW4, NW 5, NW 6, NW 11 NW, NW 12, and NW 13 suffer from poor ability to rinse, whereas other non-working examples are having a huge drawback related to post-wash dryness.
[0067] It can be observed that although, non-working examples NW1-14, and 23 are transparent and possess fairly acceptable pH values but because of the unsuitable sensorial features associated with them, they are non-working examples of the present disclosure.
[0068] On the other hand, working examples 15 to 20 have good sensorial features of good foam, quick rinsing, and no dryness associated post-wash. The reason for the same may be attributed to the working examples have all the components within the disclosed ranges.
Example 2
Preparation of the composition
[0069] The process for preparing the disclosed composition is relatively simple. The process can be summarized in the following steps:
The non-ionic surfactants were contacted with the at least one oil in a mixer to obtain a first mixture. Subsequently, the anionic surfactants were contacted with the first mixture, to obtain a second mixture. The amphoteric surfactants were contacted with the second mixture, to obtain a third mixture. Water and the at least one humectant were contacted with the third mixture, to obtain a fourth mixture, and the at least one excipient was contacted with the fourth mixture and further processed to obtain the composition. All the mixtures were obtained by contacting the respective

ingredients at a temperature in a range of 50-55°C and by maintaining stirring at 100 rpm. The same procedure was followed for preparation of working and non-working examples as mentioned in the previous section.
[0070] Overall, the present disclosure provides a cleansing formulation is devoid of alcohols, silicone, and synthetic polymers. In spite of the same, the composition of the present disclosure was found to possess equivalent sensorial features as compared to known cleansing formulations available in the market. Advantage of the present disclosure;
[0071] The present disclosure discloses a cleansing formulation comprising: (a) a combination of at least one anionic surfactant, at least one non-ionic surfactant, and at least one amphoteric surfactant; (b) at least one oil in specific weight ratio. The composition can further comprise of at least one humectant and also at least one excipient. One of the significant advantage of the present disclosure is that the composition is essentially free of alcohol, synthetic polymers, and silicone which can be harmful to the skin and also is an environmental hazard. Despite of being free of the above-mentioned components, the composition is able to exhibit good sensorial features. Also provided, is a process for preparing the composition, which is relatively simple and is relatively inexpensive. The absence of polymers, and silicone also provide economical advantage as the cost of production can be minimized.
