Description

Title of the invention: Composition of cleansing milk and its application. Scope of the invention.

[0001] This disclosure relates to the field of personal care products, in particular, a cleansing milk composition. This disclosure also relates to a use of the composition for cleansing and makeup removal and associated processes. CONTEXT OF THE INVENTION

[0002] Cosmetic compositions that provide an aesthetic effect to the skin are widely used. These cosmetic products have been developed for longer wear and with transfer-resistant properties. However, removing such compositions has become a lengthy skincare routine. Therefore, a cleansing composition that can easily remove these cosmetic compositions from the keratinous surface is equally desirable.

[0003] Nevertheless, the use of such cleansing compositions presents associated challenges in achieving the desired texture, stability, and post-application effect. The use of oils in such compositions facilitates makeup removal. However, these compositions often leave a very oily or greasy feeling on the skin, which in turn necessitates the use of additional products to remove the oiliness and cleanse the skin. Thus, there has always been an imbalance between effective makeup removal and a less oily feeling after use, which has led to customer dissatisfaction with the use of these cleansers.

[0004] Therefore, there is a need to develop a cleansing composition with an optimized combination of cleansing agents, and with a desired product texture that is capable of ensuring makeup removal with less of an oily effect and cleansing the skin. Summary of the invention

[0005] In one aspect of the present invention, a cleansing milk composition is proposed comprising: a) propylene glycol laurate; b) at least one oil; c) at least one polymer; and d) water.

[0006] In another aspect of the present invention, a method for cleaning a keratinous surface is proposed, the method comprising the application of the composition as disclosed herein to the keratinous surface.

[0007] In another aspect of the present invention, a non-therapeutic makeup removal method is proposed, the method comprising the application of the composition as disclosed here on a made-up keratinous surface and rinsing to remove the makeup.

[0022] Existing cleansing compositions contain higher quantities of oils, which affects their stability and also results in poor makeup removal capabilities. The texture of the composition and the post-application effects are also important criteria and impact customer satisfaction. Thus, a stable composition with enhanced makeup removal capabilities while leaving a less oily feeling on the skin after use was the most sought-after. Therefore, a composition with a specific combination of oils and polymers in proportional quantities was used to obtain a stable cleansing milk composition with enhanced cosmetic properties.

[0023] Accordingly, the present invention provides a cleansing milk composition comprising: a) propylene glycol laurate; b) at least one oil; c) at least one polymer; and d) water. The cleansing milk composition is a milky white composition with improved stability, the desired texture, and enhanced ease of application. The cleansing milk composition of the present invention is less foaming or non-foaming and imparts less of a greasy effect to the keratinous surface. The present invention further provides a method for cleaning a keratinous surface, the method comprising applying the composition to the keratinous surface. The present invention also provides a non-therapeutic method for removing makeup, the method comprising applying the composition to a made-up keratinous surface and rinsing to remove the makeup.

[0160] Composition Cl (according to the present invention) was prepared by mixing the components in a specified weight and a sufficient quantity of water as shown in Table 1. Similarly, compositions C2, C3, C4 and C5 were also prepared by varying the amount of propylene glycol laurate as mentioned in Table 1 below.

[0161] The comparative CPI composition was prepared by mixing said components as mentioned in Table 1 without propylene glycol laurate.

[0163] For the purposes of this disclosure for the makeup removal studies, a frictiometer (Tribomaster TL-201- Sa Trinity Lab, Inc) and a colorimeter (Spectrophorometer Konica Minolta CM-700d) were used; and the makeup removal studies were performed on a bioskin (No 10C #WHITE).

[0164] Protocol: i. Preparation Protocol: The color of the bioskin was measured at 5 points within a 3 cm x 3 cm area using a handheld colorimeter. The color values ​​were indicated by "L", "a", and "b", where "L" represents lightness and "a" and "b" represent color elements. Next, approximately 0.015 g of liquid foundation was applied evenly to the 9 cm² area and dried with a hairdryer for 2 minutes until the surface was completely dry. Once the liquid foundation was completely dry, the color in the area of ​​the bioskin (made-up skin) with the dried foundation was measured with the colorimeter. The difference between the color value of the bare bioskin and the color of the bioskin with the dried foundation was calculated as follows (Equation i). Here, AEmax refers to the maximum value corresponding to the case where the foundation was completely removed compared to the bare bioskin.

[0165] AEmax = ^(AL^+Aa^+Ab!2) (i)

[0166] where ALi = value L for Bioskin nude - value L for Bioskin + foundation

[0167] Aai = a value for Bioskin nude - a value for Bioskin + foundation

[0168] Abi = value b for Bioskin nude - value b for Bioskin + foundation i. Removal Step: Foundation removal was studied using a frictiometer. The frictiometer parameters were set to a distance of 50 mm, a speed of 1200 mm / min, and 20 repetitions. The prepared (made-up) bioskin from the preparation step was placed and secured on the base of the frictiometer. It was positioned directly below its adapter. A cotton ball soaked in 1 g of the composition was attached to the frictiometer adapter and placed horizontally with the bioskin. The distance between them was adjusted and maintained so that they would simply adhere to each other. 100 g of external weight was placed on the adapter, and the measurement began. The base of the frictiometer was moved to the left, and the bioskin was wiped with the cotton ball to the right, as the adapter was secured in the 100 g force position. Once the frictiometer has been moved over cotton to a At a distance of 50 mm, the frictiometer was moved backward to return to its original position, and consequently, the adapter was held in place during its return. The adapter was then released, making contact with the bioskin again, and wiped by the frictiometer. This process was repeated until the bioskin had been wiped 20 times. Rinsing was performed using the same protocol. Cotton was soaked in 2 g of purified water and attached to the adapter. The bioskin was then removed and dried for 1 minute using a hairdryer. ii. Evaluation step: The completely dried bioskin was used for the evaluation step. 5 points within the area were measured and the % makeup removal (% of liquid foundation removal) was calculated as follows (Equation ii).

[0169] % makeup removal = (average AE / maximum AE)*100 (ii)

[0170] The average of 5 points was calculated by the following equation iii.

[0171] AEmean = a / (AL22+Aa22+Ab22) (iii)

[0172] where AL2 = L value for cleansed skin - L value for Bioskin+foundation

[0173] Aa2 = a value for cleansed skin - a value for Bioskin+foundation

[0174] Ab2 = value b for cleansed skin - value b for Bioskin+foundation

[0175] Observations and results: The % makeup removal data obtained for the prepared compositions are summarized in Table 2. As shown in Table 2, the makeup removal capacity in % for compositions Cl, C2, C3, C4, and C5 was > 60% (score A) and for CPI < 50% (score C). The comparative CPI compositions showed only 49% makeup removal capacity.

[0176] [Tables2] Composition Cl C2 C3 C4 C5 CPI Makeup Removal Ability 63% 65% 69% 63% 66% 49% Makeup Removal Ability Score AAAAAC

[0177] The makeup removal capacity data in % revealed that the cleansing milk compositions of the present invention were capable of effectively removing makeup. The comparative CPI composition without propylene glycol laurate exhibited minimal makeup removal, thus confirming that the composition comprising the specific components as disclosed in the present invention provided enhanced makeup removal with little or no oily effect on the skin.
