Abstract
Description
Field of the Invention
[0001] The present invention relates to the field of cosmetic compositions, in particular to a transparent essence-like cleaning composition. The present invention also relates to a preparation method of the composition and a method for treating a keratin surface. Background of the Invention An optimized cleansing regimen is the first critical step to achieving acne-free skin. Acne-prone skin is highly sensitive to soaps, harsh surfactants, and high pH, which are common in basic cleansing products on the market. Therefore, using such products can aggravate existing acne and is not the right way to cleanse acne-prone skin.
[0003] Some cleaning products claiming to be mild and moisturizing to the skin have captured the consumer market. In addition, these cleaning products contain certain anti-acne ingredients. However, the combination of mild cleansers and anti-acne agents leads to some deficiencies in product stability and ultimately fails to meet consumer expectations. In addition, such cleaning products suffer from stability issues due to elevated temperatures, which affects storage stability and shelf life. Furthermore, it is also important to keep such cleaning products homogeneous throughout their shelf life.
[0004] Therefore, there is a need to develop a cleansing composition that has an optimized combination of mild cleansing agents and acts as an effective anti-acne agent with desired product texture and stability. Summary of the invention

[0067] The present disclosure will now be described using examples, which are intended to illustrate the implementation of the present disclosure, rather than to restrictively imply any limitation to the scope of the present disclosure. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those of ordinary skill in the art to which the present disclosure belongs. Although methods and materials similar or equivalent to the methods and materials described herein can be used when practicing the disclosed methods and compositions, only exemplary methods, devices and materials are described herein. It should be understood that the present disclosure is not limited to the specific methods and experimental conditions described, and such methods and conditions are applicable.
[0068] In the following examples, unless otherwise specified, all percentages are based on the weight of the total weight of the composition. The percentages are the weight percentages of the active ingredients or active substances.
[0069] Example 1 Cleaning composition Cleaning compositions C(1) to C(6) according to the present disclosure provided in Table 1 were prepared as follows.
[0070] The method comprises mixing the phase A ingredients with water at a temperature of about 75 to 80° C. to obtain a first mixture. The phase B ingredients are added to the main container together with the first mixture at a temperature of about 75 to 80° C. and homogenized to obtain a second mixture. Then, the phase C ingredients are added to the second mixture at about 75 to 80° C., mixed thoroughly and cooled to below 65° C. to obtain a third mixture. The phase D ingredients are premixed and then added to the third mixture, and then the phase E ingredients are added at about 45 to 50° C. and mixed under continuous stirring to finally obtain a clear and uniform composition.
[0071] Similarly, comparative compositions CP(1) to CP(10) were prepared with the ingredient groups shown in Table 2 below in their respective weight %.
[0072] Table 1
[0073] Table 2
[0074] Example 2 Evaluation of composition Viscosity measurement The viscosity of the composition prepared in Example 1 was measured using an LR Lamy rheometer (Rheometer RM200 Touch with M3 spindle). Each test composition was filled into a cup fixed in the frame of the instrument, and then the viscosity was measured. The final reading at 600 seconds was recorded.
[0075] Determination of foam volume Prepare a 1% sample solution containing the test composition and hard water. The sample solution is mixed at a constant speed for a period of about 60 seconds and then transferred to a graduated cylinder. The foam is leveled and the foam volume of each sample solution is recorded.
[0076] pH Measurement The pH of the test composition was measured using a Mettlor Toledo pH meter, calibrated with buffer. The pH of the composition was measured at room temperature, about 25°C.
[0077] Measurement of transepidermal water loss (TEWL) Clean the surface of the stratum corneum (SC) sample with isooctane and place the sample in a container of TEWL. Then immerse the sample container in Evian water to wet the SC and then dry it in ambient atmosphere for at least 1 hour. The surface of the SC sample was pre-wetted with 10 μl of a mixture of water and n-propanol (8:2) and then conditioned in a glove box with a controlled atmosphere (30°C, 30% RH) for 8 hours. Record the reference TEWL measurement value "T0".
[0078] The SC samples were then immersed in the test composition diluted 4 times (25%) with Évian water for 2 hours, gently agitated on a shaker, and rinsed three times in succession with Évian water. The samples were left at room temperature for at least 4 hours to ensure drying. The SC samples were then placed in a temperature and humidity controlled chamber and equilibrated at 30°C and 30%RH. After overnight equilibration, the TEWL measurement "T1" was recorded.
[0079] Zein score The irritation of surfactants in the composition was evaluated using the Zein Solubility Test, where Zein is a yellow corn protein similar to keratin found in the skin, has limited solubility in water and is denatured (dissolved) by surfactants. The ability of surfactants to denature and dissolve zein is related to its skin irritation potential. Soluble zein was measured using a modified Lowry method using a spectrophotometer. The absorbance is related to the solubility of zein, which in turn is considered a measure of the irritation potential or irritation of the product. The irritation of the analyzed samples was graded and compared using a 1.5% sodium laureate sulfate (SLS) solution as a positive control. The irritation data of the test compositions are expressed as a percentage of the SLS score.
[0080] Appearance and texture analysis The appearance and texture of the compositions were analyzed using a Datacolor light box. The test samples were placed in a clear glass beaker against the black background of the Datacolor light box. The light source was adjusted and each test composition was observed for any particles or cloudiness or translucency.
[0081] Customer feedback To understand the cosmetic potential of the composition (for dry or wet face), a customer study was conducted. The study was conducted on 16 customers aged between 18 and 24 years. Customers were asked to provide feedback on texture, translucency and radiance.
[0082] Instrument testing According to the standard protocol ASTM 2783, the test microorganism Propionibacterium acnes ATCC 11827 ( Cutibacterium acnes ATCC 11827), the antimicrobial activity of the compositions was evaluated at a temperature of 25°C ± 1°C. The test compositions were neat (NEAT) C(7) and C(7) diluted to 75% in water. The % bactericidal activity was measured over a period of 1 minute.
[0083] Example 3 result Viscosity measurement The viscosity of the composition of the present disclosure and the comparative composition at different time periods and temperatures was measured. The obtained viscosity values are shown in Table 3 below.
[0084] Table 3 ND-not detected.
[0085] It can be observed that the viscosity of the disclosed composition is within the desirable range of 400 to 3000 cps, while the comparative composition exhibits a very low viscosity, is therefore easy to flow, and is not suitable for easy spreading and retention on the skin. The good viscosity of the disclosed composition can be attributed to the combination of anionic and nonionic surfactants. It can be noted that CP (1) and CP (2) do not contain nonionic surfactants, while CP (3) does not contain anionic surfactants (e.g., sulfonate surfactants), which is different from the disclosed composition. The disclosed composition presents an essence-like appearance with a desirable viscosity that is easy to spread on wet and dry skin. In addition, the disclosed composition provides the possibility of staying on the skin for 1 to 5 minutes, thereby providing sufficient time for skin nourishment.
[0086] Determination of foam volume The foam volume of the disclosed and comparative compositions was measured and is tabulated below. It was observed that the combination of surfactants (e.g., anionic, amphoteric, and nonionic surfactants) disclosed herein provided better foam volume compared to compositions not containing the combination of these surfactants.
[0087] Table 4
[0088] pH Measurement The measured pH of the composition is shown in Table 5 below, wherein the composition is in a favorable pH range of 5 to 5.5 even at elevated temperature.
[0089] Table 5
[0090] TEWL and zein measurements TEWL analysis and zein measurement were performed on the compositions of the present disclosure and the comparative compositions according to the above protocol, and the corresponding values are shown in Table 6 below.
[0091] The disclosed compositions containing the surfactant combination do not compromise the integrity of the SC barrier and thus exhibit lower TEWL. In addition, the disclosed compositions are milder to skin proteins as they exhibit lower zein scores compared to compositions not containing the desired surfactant combination.
[0092] Table 6
[0093] Appearance and texture analysis Observations on the appearance and texture of the compositions are shown in Table 7. It can be clearly understood that the compositions of the present disclosure are transparent and stable even at higher temperatures for a long period of time, thereby providing increased storage stability and shelf life.
[0094] Table 7
[0095] Customer feedback 15 out of 16 consumers believe that the composition of the present disclosure is more preferred than their conventional cleaning products for the benefits of improving skin clarity, radiance, and controlling acne. After using the composition of the present disclosure, consumers experience significant benefits in terms of acne and clarity.
[0096] Instrument testing The antimicrobial activity study of the disclosed composition demonstrated that the composition was effective in killing microorganisms both in neat (NEAT) form and in its diluted form, as shown in Table 8 below. Thus, even in dilution, the cleansing composition was effective in killing microorganisms, demonstrating its enhanced cosmetic benefits.
[0097] Table 8
[0098] Thus, it is observed that the use of specific ingredients within the disclosed weight ranges as disclosed in various embodiments herein facilitates achieving cosmetic compositions having desired sensory properties and stability.
