Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a double-layer facial cleansing oil with a warm feel and a preparation method thereof. Background Art

[0002] In today's "face value era", people pay more and more attention to their appearance. Makeup, as a kind of etiquette and image-building concept, is accepted by more and more people, and the color cosmetics market has entered a stage of rapid development. As a result, consumers pay more and more attention to deep cleansing, and the makeup removal product market is booming, with an annual growth rate of more than 15%. The heavy makeup required for performances and the light makeup in daily life have different needs in different occasions, and the makeup removal products required in the makeup removal process are of course different. At the same time, with the continuous upgrading of consumer demand, sensory experience has added a new dimension to consumers' choice of products, and the concepts of temperature and physical sensation have exploded. The growth rate of many popular concepts exceeds 100%, among which ice feeling, water feeling, heat feeling, novel dosage forms, differentiated appearance, and unique usage methods have created new products with high market acceptance. Temperature breaking can attract the attention of people who try it out. There are still relatively few temperature products in China compared with Japan and Europe and the United States, which is a market selling point that can be expected.

[0003] Makeup removal also requires a sense of ritual. Currently, the double-layer products on the market are basically double-layer makeup removers, which do not have a warming effect. Double-layer makeup removers are too thin after shaking and still need to be used with makeup remover cotton. Shaking and rubbing can easily damage the cuticle. This kind of friction on the skin can also cause irritation and barrier damage, and is not suitable for sensitive skin. At present, most of the products that claim to have a warming effect are makeup remover creams. The texture of makeup remover creams is heavy, easy to make eyes and face blurry, difficult to emulsify and wash, and have poor stability. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a double-layer cleansing oil with a warm feeling that activates microcirculation and is clear and transparent. The oil adopts a warm feeling brought by polyol and skin massage, has a novel appearance, and forms a two-layer stable stratification of oil and alcohol through a golden ratio: upper layer: lower layer (light green transparent liquid) = 7:3. After shaking, a reverse micelle microemulsion is obtained, which is extremely rapidly emulsified when in contact with water, and can remove makeup efficiently and quickly without the need for secondary cleaning, while retaining moisture while removing makeup.

[0064] It can be seen from the experimental results in Table 3 that the double-layer cleansing oil prepared in the embodiment has a moderate delamination time, does not need to be shaken twice in one makeup removal, is convenient and labor-saving, and has a clear and flat interface. However, the cleansing oil in the comparative example has a slow delamination speed, an unclear interface, and is opaque, which affects the overall appearance and brings a bad usage experience to consumers.

[0065] 3. Makeup removal performance test:

[0066] Test samples: double-layer makeup remover oils of Examples 1-4 and Comparative Examples 1-3.

[0067] Study population: 30 female volunteers aged 20-40 were selected, 15 of whom had dry skin and the other 15 had oily skin. All of them had no serious systemic diseases, no immunodeficiency or autoimmune diseases, no active allergic diseases, no highly sensitive constitutions, and had not used hormone drugs and immunosuppressants in the past month.

[0068] Test method: For each sample, two female volunteers with dry skin and two female volunteers with oily skin were selected. The samples were used five times, once a day, for a total of five days. The test site was the face of the volunteers. After the volunteers used the same cosmetics to apply makeup, the same amount of the material was taken and rubbed for 20 seconds. After emulsification with water, the sample was rinsed for makeup removal test. The emulsification speed, easy rinsing degree, oil film feeling after use, light feeling, mildness and makeup removal speed were scored (1-5 points, 1 point is the worst and 5 points is the best), and the average score was taken. The results are shown in Table 4.

[0069] Table 4

[0070]

[0071] As can be seen from Table 4, the comparative examples and the examples show that when the ratio of oleyl alcohol is 7:3, the makeup removal effect is above 4 points.

[0072] 4. Temperature sensory effect test

[0073] 1) Environmental conditions: temperature 22-25℃, humidity 40-50%; number of testers: 10 people.

[0074] 2) Test method: The tester cleans the skin on the inside of the arm, then wipes the skin surface dry, tests the initial temperature of the skin on the inside of the arm, takes 30g of the product, massages on the skin surface of the same position of 25cm2, massages evenly for 5 minutes, and then uses an infrared thermometer to test the surface temperature. After the test, rinse with clean water.
