Description

A CLEANSING COMPOSITION AND METHODS THEREOFFIELD OF INVENTION

[0001] The subject matter of the present disclosure relates to the field of personal care products, in particular, to a cleansing composition for keratin surfaces, preferably skin. The present disclosure further relates to a method of cleansing keratin surfaces, such as skin.BACKGROUND OF THE INVENTION

[0002] The use of cleansing products is an essential part of a personal care routine. A good cleanser removes dirt, oil, and other impurities, helping to unclog the pores of the skin. It also removes dead skin cells, and makeup, helps maintain the natural moisture of the skin, and prevents dryness, and irritation. These products also help maintain the natural pH balance of the skin, which is important for preventing damage and dryness.

[0003] However, to fully utilize the cleaning compositions, it is essential to optimize the texture and packaging. An optimum viscosity of the composition is desirable for its packaging and complete utilization. Over the years several polymeric components have been used to control the viscosity of these compositions. Consumers are increasingly turning away from chemi cal -based polymeric components to other alternatives to optimize the viscosity of the composition. Therefore, cleansers that not only offer effective cleansing, foaming, and transparent texture but also ensure a minimal environmental footprint are appreciated by today’s consumers.

[0004] Hence, there is a need in the art to develop a cleansing composition with optimum viscosity and thickness using environmentally friendly components instead of high molecular weight polymers.SUMMARY OF THE INVENTION

[0005] In an aspect of the present disclosure, there is provided a composition comprising: (a) at least one foaming surfactant, preferably an anionic surfactantselected from sulfonate surfactant(s); (b) at least one fatty acid ester of monoglycerol; and (c) at least one linear fatty acid ester of polyglycerol.

[0006] In another aspect of the present disclosure, there is provided a method for cleansing a keratin surface, such as skin, the method comprising: applying the composition as disclosed herein, with water on the skin, followed by working the composition into a foam and rinsing off the composition.

Functionally equivalent products, compositions, formulations, and methods are clearly within the scope of the disclosure, as described herein.

[0022] As discussed in the background, there is a need in the state of art to develop a cleansing composition with optimal viscosity using environmentally friendly components. In general, cleansing composition suffers from low viscosity making them prone to dripping and leakage, which complicates packing and transport. Additionally, the low viscosity and thickness of the composition can make it difficult to control the amount of product dispensed during use, leading to inconsistent application and potentially inadequate cleansing. Hence, over the years acrylate-based polymers have been commonly used to increase the viscosity, texture, stability and thickness of cleansing compositions. However, theenvironmental impact of using these polymers is of great concern. Therefore, consumers are looking for cleansing formulations that do not use non-biobased and non-biodegradable components.

[0023] Accordingly, the present invention provides a composition comprising foaming surfactants, preferably an anionic surfactant selected from sulfonate surfactant(s), at least one fatty acid ester of monoglycerol and at least one linear fatty acid ester of polyglycerol, designed to deliver the right texture and viscosity without using non biobased / biodegradable polymer.

[0127] In the following examples, unless indicated otherwise, the percentages are indicated by weight of the total weight of the composition. The percentages are weight percentages by active ingredient, or active material.Example 1Cleansing compositions

[0128] Composition Cl- For preparation of composition Cl (according to the present invention) 2.45 % (w / w) of disodium laureth sulfosuccinate (sulfonate surfactant), 2.64 % (w / w) of sodium lauroyl sarcosinate, 1.5 % (w / w) of disodium cocoyl glutamate (and) sodium cocoyl glutamate (amino-acid surfactants), 4.5 % (w / w) of coco-betaine (amphoteric surfactant), and quantity sufficient water were mixed and heated to 65-70 °C to obtain base. Subsequently, 0.50% (w / w) of glyceryl laurate (fatty acid ester of monoglycerol), and 0.95% (w / w) of polyglyceryl 4-caprate (fatty acid ester of polyglycerol) were added to the prepared base and cooled to 40-45°C to obtain a base mixture. Simultaneously, chelating agent, additives premix comprising 0.01% (w / w) tetrasodium EDTA, 1.80% (w / w) of lactic acid, 0.88% (w / w) of potassium hydroxide, 0.98% (w / w) of sodium chloride and 0.19% (w / w) sodium benzoate (additives) were mixed in quantity sufficient water separately. The prepared chelating agent, and additive premix were then added to the prepared base mixture, continuously stirred and cooled to obtain composition Cl (Table 1).

[0129] Similarly, compositions C2 and C3 (according to the invention) and comparative compositions CPI to CP7 were also prepared with the set of components in their corresponding weight % as indicated in Table 1 and Table 2 below.Table 1Table 2Example 2Stability studies

[0130] Compositions prepared in Example 1 were analyzed at 50°C for their accelerated stability, for 2 weeks in stability chamber.

[0131] Protocol: The compositions prepared in Example 1 were analysed to determine its prototype scoping by visual examination of their aspect / clarity. The pH of the prepared compositions was also measured at room temperature, using calibrated Mettlor Toledo pH instrument.

[0132] Observations: The aspect / clarity observations and observed pH for compositions Cl to C3 and CPI to CP7 are summarized in Table 3.Table 3Viscosity measurement

[0133] Protocol: The compositions prepared in Example 1, Cl to C3 (according to the present invention) and comparative compositions CPI to CP7 were subjected to viscosity measurements using LR Lamy Rheology instrument, RheometerRM200 Touch with M3 spindle were determined for various time period and at varying temperatures, in particular at 25°C for about 10 minutes. Each composition was filled independently in the cup attached to the rim of the instrument and the viscosity was measured.

[0134] Observations: The observed viscosity for all the compositions Cl to C3 and comparative compositions CPI to CP7 are summarised in the Table 4 below.Table 4

[0135] Results: As shown in Table 4, compositions Cl to C3 exhibited considerably higher viscosities (> 200 CPS) compared to the comparative compositions CPI to CP7. The higher viscosities of Cl to C3, could be attributed to the unique combination of the sulfonate surfactant, fatty ester of monoglyceroland linear fatty acid ester of polyglycerol. It is noteworthy that the comparative compositions CPI to CP7 were devoid of either sulfonate surfactant or fatty acid ester of monoglycerol or / and linear fatty acid ester of polyglycerol, and hence were free flowing and less suitable for packaging.EXAMPLE 3Foam stability

[0136] Protocol: Compositions C2 (according to present invention) and CP3 and CP4 (comparative compositions) as prepared in Example 1 were subjected to test their foam stability by preparing a 1% w / v solution of composition using hard water (2.652gm calcium chloride in 4000ml distilled water). The solution obtained was poured into a grinder and mixed for 60 seconds. The mixed solution was then transferred to a measuring cylinder and its initial foam volume was measured. Further, at 1 min, 2 min, and 5 min the foam volumes were recorded. The difference in foam volume between TO min and T5 min was calculated.

[0137] Observation: The foam volume of C2, CP3 and CP4 at different time are mentioned in below Table 5.Table 5

[0138] Results: As shown in Table 5, the foam volume difference (T0-T5 min) was lower for C2 compared to CP3 and CP4. Hence, the composition C2 according to the invention exhibited more stable foam formation.EXAMPLE 4Solubilization

[0139] The active solubilization of the composition C3 (prepared according to the present invention) and comparative compositions CP6 and CP7 were analysed. Each of the compositions were independently taken in a transparent beaker and evaluated against black background in light-chamber. The appearance of the compositions were observed.

[0140] The observations were recorded and mentioned in Table 6.Table 6

[0141] Results: The composition C3 did not separate, was stable as transparent system and remained completely solubilized for a longer time period.

[0142] Hence, the composition according to present invention, due to the presence of sulfonate surfactant, fatty acid ester of monoglycerol and linear atty acid ester of polyglycerol optionally along with other ingredients, synergistically provided a transparent cleansing composition. All these components helped to achieve active solubilization, higher (>200 CPS) viscosity, better foam stability and at the same time showed skin friendly low pH (~ 5).ADVANTAGES OF THE PRESENT DISCLOSURE
