Description

Technical Field

[0001] The present invention relates to the technical field of washing and care, and in particular to a two-in-one washing and removing composition and its application and products. Background Art

[0002] Women usually use some makeup products or sunscreens. These products usually contain things like color powder and physical sunscreens that are difficult to remove. So to remove these ingredients, you need to use makeup remover oils and makeup remover creams. In recent years, with the improvement of some film-forming agent technologies, film-forming agents used in makeup products and sunscreen products have become more and more common. These film-forming agents are usually highly water-resistant, and conventional surfactants are difficult to clean. After removal, you need to clean the grease and dust on the face for a second time, so you need to use cleaning products containing surfactants, which means you have to clean the skin twice, which is not only troublesome, but also due to excessive degreasing, it will damage the stratum corneum of the skin, and it is very easy to dry out, redden, and peel. According to consumer surveys, 90% of users hope to complete makeup removal and cleaning work in one go, which is efficient, convenient, and time-saving. In addition, in the cleaning category, consumers prefer products with rich foam.

[0003] Cleansing is generally achieved by using a water-based surfactant composition, and makeup removal is generally achieved by using oils and emulsifiers. However, oils and emulsifiers will greatly reduce the foaming ability of surfactants. At the same time, if oils are added to the water-based surfactant composition, emulsification is likely to occur, causing the entire system to fail. Traditional fatty alcohol polyether sulfate surfactants have better effects, strong foaming power, and strong anti-grease ability, but they are more irritating and have poor effects on makeup and sunscreen removal. Amino acid surfactants have good stability and low degreasing power, but the effect of removing makeup and sunscreen is very weak. If oils and emulsifiers are added, it is easier to defoam.

[0004] Therefore, it is difficult to strike a balance between the six points of cleansing ability, makeup removal ability, foaming ability, degreasing ability, moisturizing, and mildness and non-irritation.

[0005] Patent CN115006269A discloses a two-in-one washing and removing composition, which comprises the following components by weight: 1-10 parts of decyl glucoside; 1-10 parts of potassium cocoyl glycinate; 1-3 parts of potassium cocoate; 1-5 parts of sodium lauroamphoacetate; 1-8 parts of diethoxyethyl dicarboxylate; 1-5 parts of propylene glycol fatty acid ester; 1-3 parts of caprylic / capric glyceride polyglycerol-10 ester; and 1-10 parts of dicarboxylic acid dimethicone. Ethoxyethyl ester is compounded with propylene glycol fatty acid ester, and supplemented with specific weight portions of decyl glucoside, potassium cocoyl glycinate, potassium cocoate, sodium lauroylamphoacetate, caprylic / capric glycerides polyglyceryl-10 esters. Through the synergistic cooperation of various components, the prepared two-in-one cleaning and removing composition has strong cleaning ability and no residue; it is mild and non-irritating, has a good skin feel, and is friendly to dry skin and sensitive skin; and the overall pH value is neutral, the foam is rich, and the product has a transparent appearance.

[0006] This patent has both good makeup removal and foaming properties, but potassium cocoate is used to improve the foaming ability, which is a soap-based ingredient. In the experiment, it was found that some people would have a positive reaction in the patch test, which is not very friendly to certain groups of people, especially children. In addition, the degreasing performance of the soap base is relatively large, and there will be a feeling of dryness after cleansing; another problem with this system is that the foam has poor durability, it is easy to defoam after foaming, and it is not easy to foam again, and it is difficult to achieve the best washing feeling, so a two-in-one washing and removing composition with better mildness, good foaming, foam stability and more balanced makeup removal power is needed. Summary of the invention

[0007] The object of the present invention is to provide a two-in-one washing and removing composition with excellent foaming property and makeup removing power, wherein the composition comprises, by mass percentage:

[0008]

[0009] As an embodiment of the present invention, the fatty acyl amino acid surfactant is at least one of sodium lauroyl sarcosinate, sodium lauroyl alanine, sodium lauroyl glutamate, and sodium lauroyl glycinate.

[0010] As an embodiment of the present invention, the alkyl glycoside is at least one of C8-C10 alkyl glycoside, C10-C12 alkyl glycoside, C12-C14 alkyl glycoside and C14-C16 alkyl glycoside.

[0011] As an embodiment of the present invention, the polyglyceryl fatty acid ester nonionic surfactant is selected from at least one of caprylic / capric glyceride polyglyceryl-10 esters, polyglyceryl-10 caprylate, polyglyceryl-10 caprate, polyglyceryl-10 laurate, polyglyceryl-10 myristic acid ester, polyglyceryl-10 oleate, polyglyceryl-10 stearate, polyglyceryl-6 caprylate, polyglyceryl-6 dicaprate, polyglyceryl-5 laurate, and polyglyceryl-4 caprate.

[0012] As an embodiment of the present invention, the two-in-one washing and removing composition further comprises water-soluble polyoxyethylene glycerol fatty acid ester.

[0013] As an embodiment of the present invention, the water-soluble polyoxyethylene glycerol fatty acid ester is selected from at least one of PEG-20 glyceryl triisostearate, PEG-20 glyceryl isostearate, PEG-15 glyceryl isostearate; PEG-20 sorbitan isostearate; sorbitan polyether-40 tetraoleate and sorbitan polyether-60 tetraoleate.

[0014] As an embodiment of the present invention, the mass ratio of the fatty acyl amino acid surfactant: cocamidopropyl betaine: sodium lauroylamphoacetate: polyglycerol fatty acid ester nonionic surfactant: PEG-20 glyceryl triisostearate is 10:5:5:8:2.

[0015] As an embodiment of the present invention, the fatty acyl amino acid surfactant is sodium lauroyl sarcosinate.

[0016] The second aspect of the present invention provides the use of the two-in-one cleansing and removing composition in skin cleaning products.

[0017] As an embodiment of the present invention, the skin cleaning product is selected from facial cleanser, facial honey, facial bubble, facial mousse or shower gel.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects:

[0019] The components prepared by the present invention have a transparent product appearance and a neutral pH value. When cleaning, the skin can be cleaned by removing sunscreen, makeup, grease, dust, etc. at the same time; and the skin is also non-irritating. The makeup removing emulsifier in the ingredients forms a self-assembled layered emulsified micelle in a clean foaming surfactant (lauroyl sarcosine, cocamidopropyl betaine, decyl glucoside) system. During use, the clean foaming surfactant can form rich and dense foam, and the self-assembled layered emulsified micelle will then be released on the skin surface, quickly dissolving and removing the makeup and sunscreen ingredients on the skin surface, achieving the effect of efficient cleaning + makeup removal. At the same time, the secondary foaming and foam stabilization performances are good, and the patch is non-irritating. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The ingredients of the specific embodiments and comparative examples are shown in the following table:

[0035] Table 1 Composition and test results of each embodiment and comparative example

[0036]

[0037]

[0038] Among them, the performance test method is as follows:

[0039] (1) The cleaning power test method is as follows:

[0040] 34 qualified volunteers were selected (ensuring that the number of valid cases was no less than 33). The volunteers cleaned the curved side of the left and right forearms uniformly, and gently dried the moisture with a paper towel. Then, three skin areas with an area of ​​3cm×3cm were marked as test areas. There was at least 2cm between each area. The three test areas on the left arm were numbered L1, L2, and L3, and the three test areas on the right arm were numbered R1, R2, and R3. Sit quietly for 30 minutes, and use a microscope to collect images of each test area. According to 2.00mg / cm 2 Use the amount of BB cream sample evenly on each test area on the curved side of the left forearm; apply the lipstick sample evenly on each test area on the curved side of the right forearm. Use a microscope to capture images of each test area. Use a 1mL syringe to quantitatively use the products of Example 1 to Comparative Example 10 to clean the L1, L2, L3 and R1, R2, R3 areas, then rinse with water and gently dry with a paper towel. Sit still for 30 minutes, and use a microscope to capture images of each test area. Observe the BB cream and lipstick residues in the skin texture. Very good means that the six areas can be removed completely, good means that there is a little residue in the six areas, average means that there is a certain amount of residue in the six areas, and poor means that there is more residue in the six areas.

[0041] (2) The foaming test method is as follows: Use the Roche foam tester to test the foam height. For specific operation methods, please refer to the test method of the Roche foam tester. A foam value greater than 100 mm represents very good, a foam value greater than 80 mm represents good, and a foam value less than 60 mm represents poor.

[0042] (3) The foam persistence test method is as follows:

[0043] Take an appropriate amount (1 ml) of the product, rub your hands together to produce foam, and use a stopwatch to record the defoaming time.

[0044] Very good: The foam can last for more than 1 minute.

[0045] Good: Foam can last for 30s-1min.

[0046] Normal: Foam lasts for 5-30 seconds.

[0047] Poor: The foam disappears within 5 seconds.

[0048] Very bad: The foam disappears during kneading.

[0049] (4) The secondary foaming ability greatly reflects the washing feeling of the cleaning product. Because during the cleansing process, people usually wet their hands and face first, take the product with their hands and rub it to produce foam, and then rub it on the face after a certain amount of foaming. If the secondary foaming ability is poor, the foam will gradually disappear during the rubbing process on the face, and the washing feeling will be poor. If the secondary foaming ability is strong, the foam will become more and more abundant during the rubbing process, and the washing feeling will be comfortable.

[0050] The secondary foaming ability test method is as follows:

[0051] Wet your hands, take an appropriate amount (about 1 ml) of the product, rub your hands together to form foam. After foaming, drop clean water (about 5 ml) on your hands again, continue rubbing, and observe the foaming.

[0052] Good: It can foam twice, and the foam is rich.

[0053] General: Can foam twice, with less foam.

[0054] Poor: Very little secondary foaming.

[0055] Very bad: unable to foam again.

[0056] (5) The appearance test method is as follows: observation with naked eyes.

[0057] (6) The appearance test method after 14 days / 28 days of hot and cold shock is as follows:

[0058] Stability of hot and cold cycles: One cycle is 2 days of hot and cold cycles. Place the solution in a -18℃ constant temperature box for 1 day and in a 48℃ constant temperature box for 1 day. After returning to room temperature, observe whether the appearance of the solution has changed, such as milky white, stratification, precipitation, emulsification, turbidity, etc. Test the conditions for 14 days and 28 days respectively.

[0059] (7) The test method for makeup removal (sunscreen) is as follows:

[0060] Apply sunscreen on the arm, then wash it with the example and comparative example compositions (sunscreen products, clear strength and time are consistent), use an ultraviolet camera to take pictures, observe the residual sunscreen, and compare the performance of removing sunscreen.

[0061] Strong: Very clean, no fluorescent reflection;

[0062] Very good: taking photos in multiple dimensions, we can find its slight fluorescence emission;

[0063] Good: Slight fluorescent reflection;

[0064] Fair: Fluorescence faded, but still visible;

[0065] Poor: Compared with no cleaning, basically no removal.

[0066] (8) Makeup removal (makeup) test method is as follows:

[0067] Apply makeup to the inside of the arm, then wash it with the product, and use a stereo microscope to observe the crevices of the skin and compare the makeup residue in the crevices;

[0068] Strong: In-body observation shows that there is absolutely no residue in the gap;

[0069] Very good: In-body observation requires moving the field of vision to find slight residues;

[0070] Good: In-body observation, there is a slight residue in the gap of the visual field;

[0071] General: Residues are left in the gaps and are not completely removed, which is visible to the naked eye;

[0072] Poor: Not completely removed, visible to the naked eye.

[0075] (9) The degreasing force test method is as follows:

[0076] Sample preparation: Take smooth fresh pig skin, clean it with water, cut it into several small pieces of 50mm×50mm, take 0.01g of white oil 26#, olive oil and dimethyl silicone oil (100cst) respectively and apply them evenly on the test skin to make test pig skin small pieces, then take the same mass of cleansing bubble / cleansing honey / cleansing cream for comparative testing.

[0077] Sebum content determination: using a sebum test analyzer SM 815, using Sebumeter method to measure the lipid content of the test skin surface. The specific method is: after turning on the instrument and connecting it to the computer, open the software, replace the test probe tape by pulling it, press the test probe lightly into the instrument test hole and start timing, take out the probe and press it vertically on the skin surface, insert the probe again after 30 seconds, and press the test hole lightly once, the tape absorbs lipids and becomes transparent, the software measures the transmittance of the tape and calculates the sebum content (unit: μg / cm 2 ). For the determination of lipid content on the same skin surface, three points were randomly selected and the average of the two closest determination results was taken. The difference between the determination results of each point should not exceed 15 μg / cm 2 Otherwise, it is considered that the lipid distribution on the surface of the tested skin is not uniform and the experimental data is invalid.

[0078] The measurement environment temperature is 20°C and the relative humidity is 50%. Determination of washing effect: Use a small piece of pig skin coated with oil as the test skin. First, measure the lipid content on the surface of the test skin. Then take 3g of the prepared composition and pour it evenly on a 50mm×60mm cotton piece. Wipe the test skin from top to bottom once. After the water is naturally dried, measure the lipid content on the surface of the test skin again. Calculate the sebum reduction rate based on the sebum content measured before and after washing. Sebum reduction rate = (sebum content before washing - sebum content after washing) / sebum content before washing × 100%.

[0079] Perform three parallel experiments. If the sebum content measurement result before washing differs from the experimental results of other groups by more than 15 μg / cm2, discard the data and perform another parallel experiment. Select the two groups of data with the closest sebum reduction rate from the experimental results that meet the conditions, and take the average value of the sebum content and sebum reduction rate before and after washing.
