Description

Technical Field

[0001] This invention belongs to the technical field of personal care cosmetic products, specifically relating to a cosmetic composition, its preparation method, and its application. Background Technology

[0002] As living standards continue to improve, people's desire for beauty has become stronger. Eyeliner products can highlight and enhance the charm of the eyes, giving them a captivating look. Commercially available products mainly include solid eyeliner compacts and liquid eyeliners. Liquid eyeliners are currently widely used due to their greater convenience.

[0003] The quality of the film-forming substance in liquid eyeliner determines the overall quality of the product. A superior liquid eyeliner should be free from microbial contamination, toxicity, odor, and irritation; it should dry quickly; apply smoothly and glossily to the eyelids; and maintain its durability even under conditions of oily skin, sweat, tears, and rain. It should not dry out, bleed, or crack with long-term use. However, most liquid eyeliners on the market currently suffer from several problems, such as poor water resistance and insufficient staying power; low skin adhesion and easy smudging; poor pigment dispersion and product instability; uneven application, resulting in a grainy texture and poor user experience; and complex formulas containing many irritating and potentially risky substances, leading to symptoms like redness and itching after application. The most fundamental issues lie in maintaining the eyeliner's staying power and ensuring a gentle, low-irritant formula.

[0004] CN109381370A uses styrene / acrylate / ammonium methacrylate copolymer and styrene / acrylate copolymer as film-forming agents to prepare an eyeliner with features such as easy application, water resistance and long-lasting wear, smudge-proof properties, and removability. In order to maintain the excellent durability of the eyeliner, styrene-acrylate polymers are selected as film-forming agents. However, due to the influence of their molecular rigidity, the product is too hard, which may cause discomfort to the eyes.

[0005] CN110200893A describes the preparation of an eyeliner using octylacrylamide copolymer of acrylates and polyvinylpyrrolidone as film-forming agents. The eyeliner contains magnetic substances, which can give it the special function of wearing false eyelashes. It also contains some plant-based soothing ingredients, which can have a certain soothing effect on the eyes. However, it does not mention improving its waterproofness, abrasion resistance and durability.

[0006] CN113018244A includes stem cell secretions and graphene-polyacrylic acid-RADA16-A nanoparticles, mainly used in skincare products. Its function is to mimic the surface structure of the extracellular matrix, promoting cell migration and proliferation, providing a suitable microenvironment for cell proliferation and differentiation, and allowing the transfer of nutrients, oxygen, and metabolites within the structure, providing antibacterial, heavy metal adsorption, and nuclear contamination removal effects. CN110041497A uses graphene oxide to generate graphene-containing polyurethane, mainly used in the materials field for slow release, thus achieving long-lasting antibacterial properties. CN109369964A applies graphene to prepare composite antibacterial films, significantly improving the antibacterial activity of the composite film, possessing advantages such as broad antibacterial spectrum, high antibacterial efficiency, heat resistance, UV resistance, and good mechanical properties. However, the above patents only utilize the antibacterial effect of graphene.

[0007] Existing liquid eyeliners generally suffer from poor water resistance, poor stability, high irritation, and poor skin feel. Therefore, there is an urgent need to develop a cosmetic composition that, when applied to liquid eyeliner, can give it the characteristics of good water resistance, good sweat resistance, good stability, low irritation, good skin feel, good antibacterial properties, good abrasion resistance, and easy makeup removal. Summary of the Invention

[0008] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a cosmetic composition, its preparation method and application. When the cosmetic composition is applied to eyeliner liquid by screening and compounding the various components, the eyeliner liquid can have the characteristics of good water resistance, good sweat resistance, good stability, low irritation, good skin feel, good antibacterial properties, good friction resistance and easy makeup removal.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] In a first aspect, the present invention provides a cosmetic composition comprising, by weight, the following components: 1-30 parts by weight of graphene oxide and rhamnolipid-modified waterborne polyurethane dispersion, 5-30 parts by weight of color developer, and 40-94 parts by weight of aqueous carrier.

[0011] The cosmetic composition provided by this invention contains a waterborne polyurethane dispersion modified with graphene oxide and rhamnolipids, free of irritating solvents such as ethanol and acetone. This reduces the total solvent content in the cosmetic composition and imparts excellent water resistance, sweat resistance, abrasion resistance, and antibacterial properties. Furthermore, it provides skin-soothing effects, is soft and skin-friendly, has low irritation, and is easy to apply. Due to the stable structure of graphene oxide, the cosmetic composition is less susceptible to the effects of sweat or rain, exhibiting excellent durability and gloss. Rhamnolipids possess antibacterial capabilities, and their unique rhamnosyl ring structure has a significant soothing effect on the skin. Grafting it onto the polyurethane chain segment imparts significant antibacterial and skin-soothing effects to the polyurethane. Moreover, the cosmetic composition provided by this invention is a water-based system, which is more environmentally friendly and safer than oil-based systems, with less irritation and harm to the human body.

[0158]

[0159] The components of Comparative Examples 1-4 were mixed by stirring at room temperature to obtain the cosmetic composition.

[0160] Performance testing:

[0161] (1) Appearance and stability tests:

[0162] Take 20 g of the prepared sample and place it in a 20 mL glass bottle (28 mm in diameter, 60 mm including the cap). After leaving it at room temperature for 24 h, observe the appearance of the cosmetic composition with the naked eye. Then place it in a -5 ℃ refrigerator for 24 h, remove it and observe it after returning to room temperature. Then place it in a 40 ℃ oven for 24 h, remove it and observe the appearance of the cosmetic composition after returning to room temperature. If crystallization, precipitation, or stratification occurs and the stratification height exceeds 5 mm, it is scored as 1 point. The stratification is mainly caused by the precipitation of water, color developer, or preservative in the cosmetic composition. When water or color developer precipitates, the stratification height is the height of the lower layer. When preservative precipitates, the stratification height is the height of the upper layer. If only stratification occurs and the stratification height is between 3-5 mm (inclusive), it is scored as 2 points. If only stratification occurs and the stratification height is between 1-3 mm (inclusive), it is scored as 3 points. If only stratification occurs and the stratification height is between 0-1 mm, it is scored as 4 points. If there is no stratification, no crystallization, and no precipitation, it is considered to have good stability and is scored as 5 points.

[0163] (2) Water resistance test:

[0164] The cosmetic composition was applied to the skin and allowed to dry completely to form a film. After rinsing under tap water for 3 minutes, the residue of the cosmetic composition on the skin was observed. A score was assigned based on the residue, with 5 tests performed for each sample, and the average value was taken. The score ranged from 1 to 5 points, with higher scores indicating more residue and better water resistance. Specifically, a residue / total amount after rinsing was <0.2, scored as 1 point; 0.2 ≤ residue / total amount <0.4, scored as 2 points; 0.4 ≤ residue / total amount <0.6, scored as 3 points; 0.6 ≤ residue / total amount <0.8, scored as 4 points; and residue / total amount ≥0.8, scored as 5 points. When the average score was below X.3, it was assigned X; when the average score was between X.3 and X.7 (excluding X.3), it was assigned X.5; and when the average score exceeded X.7 (excluding X.7), it was assigned X+1.

[0165] (3) Sweat resistance test:

[0166] The cosmetic composition was applied to the skin and allowed to dry completely to form a film. A non-woven fabric soaked in artificial sweat was then used to wipe the applied area. The area was wiped 10 times with even pressure. The residue of the cosmetic composition was scored from 1 to 5 points. A higher score indicates more residue and better sweat resistance. Five tests were conducted for each sample, and the average result was taken. The score was as follows: 1 point for residue / total amount < 0.2; 2 points for 0.2 ≤ residue / total amount < 0.4; 3 points for 0.4 ≤ residue / total amount < 0.6; 4 points for 0.6 ≤ residue / total amount < 0.8; and 5 points for residue / total amount ≥ 0.8. The average score was X when below X.3, X.5 when between X.3 and X.7 (excluding X.3), and X+1 when exceeding X.7 (excluding X.7).

[0167] (4) Friction resistance test:

[0168] The cosmetic composition was applied to the skin and allowed to dry completely to form a film. Then, the applied area was wiped off with a dry non-woven cloth, wiping 10 times with even pressure. The residue was scored from 1 to 5 points, with higher scores indicating more residue and better abrasion resistance. Five tests were conducted for each sample, and the average score was taken. A score of 1 was given for a residue amount / total amount < 0.2; 2 points for 0.2 ≤ residue amount / total amount < 0.4; 3 points for 0.4 ≤ residue amount / total amount < 0.6; 4 points for 0.6 ≤ residue amount / total amount < 0.8; and 5 points for residue amount / total amount ≥ 0.8. The average score was X when below X.3, X.5 when between X.3 and X.7 (excluding X.3), and X+1 when exceeding X.7 (excluding X.7).

[0169] (5) Makeup removal performance test:

[0170] The cosmetic composition was applied to the skin and allowed to dry completely to form a film. Then, a dry non-woven cloth soaked in the same amount of makeup remover was used to wipe the composition off. The cloth was wiped twice with even pressure. The ease of removal was scored from 1 to 5 points, with higher scores indicating easier removal, less residue, and better makeup removal performance. Five tests were conducted for each sample, and the final result was the average. A score of 5 is given if the residual sample amount / total amount is <0.2; 4 is given if 0.2 ≤ residual sample amount / total amount is <0.4; 3 is given if 0.4 ≤ residual sample amount / total amount is <0.6; 2 is given if 0.6 ≤ residual sample amount / total amount is <0.8; and 1 is given if the residual sample amount / total amount is ≥0.8. When the average score is below X.3, X is given; when the average score is between X.3 and X.7 (excluding X.3), X.5 is given; and when the average score exceeds X.7 (excluding X.7), X+1 is given.

[0171] (6) Skin feel test:

[0172] Twenty-one participants, aged 18-45 years with a male-to-female ratio of 1:2, rated the skin feel of the cosmetic composition after it was applied to the upper eyelids and formed a film. Scores ranged from 1 to 5, and the average score was calculated. A higher average score indicated a better skin feel. 1 point represented a grainy and heavy feel with noticeable oiliness; 2 points represented no graininess but some heaviness and oiliness; 3 points represented no graininess, moderate feel, and no noticeable oiliness; 4 points represented no graininess, good feel, and no oiliness; and 5 points represented no graininess, light feel, and no oiliness. Scores below X.3 were assigned the value X; scores between X.3 and X.7 (excluding X.3) were assigned X.5; and scores above X.7 (excluding X.7) were assigned X+1. The details of the test group are shown in Table 1 below.

[0173] Table 1

[0174]

[0175] (7) Antibacterial test:

[0176] The diameter of the inhibition zone of the cosmetic composition against the test strains (Staphylococcus aureus, Escherichia coli, and Candida albicans) was determined using the agar perforation method. Kathon was used as a positive control, and sterile water as a negative control. The size of the inhibition zone was scored, with 5 points for Kathon results (inhibition zone diameter greater than 2 cm) and 1 point for sterile water results (inhibition zone diameter less than 0.5 cm). A higher score indicated a better antibacterial effect of the cosmetic composition. Five tests were performed for each sample, and the final result was the average. The score is as follows: 4 points for a diameter of inhibition zone between 1.5-2 cm (excluding 1.5 cm), 3 points for a diameter of inhibition zone between 1-1.5 cm (including 1.5 cm), and 2 points for a diameter of inhibition zone between 0.5-1 cm (including 1 cm). When the average score is below X.3, X is taken; when the average score is between X.3 and X.7 (excluding X.3), X.5 is taken; when the average score exceeds X.7 (excluding X.7), X+1 is taken.

[0177] (8) Stimulation test:

[0178] The irritation of cosmetic compositions was tested using a human patch test. Subjects (with the same distribution as the skin sensitivity test group) were given a comprehensive score based on their subjective feelings and the resulting redness and swelling. The score ranged from 1 to 5 points, with higher scores indicating a milder cosmetic composition. Five tests were conducted for each sample, and the final result was the average. A score of 1 indicates the presence of skin damage or blisters; 2 indicates no skin damage or blisters, but noticeable redness and swelling; 3 indicates no skin damage or blisters, but relatively noticeable redness and swelling (slight swelling); 4 indicates no skin damage or blisters, but slight redness and swelling (no swelling); 5 indicates almost no change in skin condition. When the average score was below X.3, it was assigned the value X; when the average score was between X.3 and X.7 (excluding X.3), it was assigned the value X.5; and when the average score exceeded X.7 (excluding X.7), it was assigned the value X+1.

[0179] The cosmetic compositions provided in Examples 1-8 and Comparative Examples 1-4 were tested according to the above test methods, and the results are shown in Table 2:

[0180] Table 2

[0181]

[0182] As shown in Table 2, the cosmetic compositions provided in Examples 1-8 exhibit significantly good water resistance, sweat resistance, and abrasion resistance, with the cosmetic compositions provided in Examples 1-3 demonstrating even superior overall performance. Example 6, due to the excessive addition of isocyanate hard segments, suffers from a poor skin feel and is more difficult to remove makeup from. Examples 2 and Comparative Example 1 demonstrate that introducing a certain amount of graphene oxide into the polyurethane segments can improve the abrasion resistance, water resistance, and sweat resistance of the cosmetic compositions. Examples 2 and Comparative Example 2 show that introducing a certain amount of rhamnolipids into the polyurethane segments can significantly improve the antibacterial properties of the cosmetic compositions and reduce their irritation. As can be seen from Example 3 and Comparative Example 4, simply performing physical mixing without grafting graphene oxide and rhamnolipid onto the polyurethane segments cannot effectively improve the various properties of the cosmetic composition. Overall, the examples show that introducing appropriate amounts of graphene oxide and rhamnolipid segments onto the polyurethane segments is beneficial for improving the waterproof, sweatproof, friction-resistant, skin-feel, and antibacterial properties of the cosmetic composition. It can also soothe the skin, reduce the irritation of the cosmetic composition, and does not affect its makeup removal performance.
