Description

Technical Field

[0001] The present invention relates to an oil-control composition inclusion and its preparation and application, belonging to the technical field of washing and care products, and particularly to an inclusion of a composition with oil-soluble oil-control / anti-dandruff effects, its preparation method, and its application in washing and care products. Background Art

[0002] With the rapid economic development, many factors such as air pollution, climate change, accelerated pace of life, and increased work pressure have an impact on people's scalp health. Oily scalp, dandruff, hair loss, and itchy scalp are all common scalp problems. These scalp problems are interrelated and related to sebum secretion, damaged barrier, scalp inflammatory response, and scalp microecology. Abnormal sebum secretion, on the one hand, unsaturated fatty acids and squalene in sebum will be oxidized and stimulate the scalp, causing an inflammatory response in the scalp. On the other hand, excessive secreted oil is easily utilized by scalp microorganisms such as Malassezia, leading to the imbalance of the scalp microecology, damaged scalp barrier, and the generation of dandruff.

[0003] In past research, we found that magnolol and honokiol have excellent oil-control and anti-dandruff effects, and due to their oil-soluble characteristics, they are very suitable for use in wash-off products. In order to further improve the residual amount of magnolol or honokiol on the scalp, the present invention further upgrades the encapsulation of magnolol and honokiol.

[0004] In patent CN108743539A, cationic lipid nanoparticles encapsulating honokiol and their preparation and application are disclosed, and the encapsulation of honokiol is applied to the treatment of cardiovascular diseases. However, this method is cumbersome and costly, and is not suitable for use in washing and care products.

[0005] In patent CN113440426B, a double encapsulation of honokiol, its preparation method, and application are also disclosed, in which honokiol is dissolved in an oil and then wrapped into liposomes for application in regulating gastrointestinal function. This method is also not very suitable for shampoo products because the liquid oil used to dissolve honokiol will affect the foam performance of the shampoo product and the fluffiness of the hair after using the product.

[0091]

[0092] Table 3 is an application comparative example containing active ingredients.

[0093] Table 3 Formulation composition of application comparative examples in oil-control shampoo (mass percentage %)

[0094]

[0095] The preparation methods of the oil-control shampoos in application examples 1-5 and application comparative examples 1-5 of the present invention include the following steps:

[0096] S1. Add the water and cationic guar gum in phase A to the emulsifying pot, homogenize until completely dispersed, start stirring, heat up to 75-85 °C, and keep warm for 10-30 min;

[0097] S2. Add the lauryl hydroxysulfobetaine and sodium cocoyl isethionate in phase B to the emulsifying pot in sequence, and keep warm and stir at 75 °C for 20-30 min;

[0100] The following are the contents of the efficacy test examples respectively.

[0101] I. Stability test

[0102] Follow up the product stability of application examples 1-5 and application comparative examples 1-5 at 48 °C, and evaluate whether there is a problem of yellowing at high temperature. The high temperature stability test results are shown in Table 4.

[0103] Table 4 High temperature stability test of application examples and application comparative examples

[0104] Sample Day 1 Day 7 Day 14 Day 28 Application Example 1 Transparent and colorless Transparent and colorless Transparent and colorless Transparent and colorless Application Example 2 Transparent and colorless Transparent and colorless Transparent and colorless Transparent and colorless Application Example 3 Transparent and colorless Transparent and colorless Transparent and colorless Transparent and colorless Application Example 4 Transparent and colorless Transparent and colorless Transparent and colorless Transparent and colorless Application Example 5 Transparent and colorless Transparent and colorless Transparent and colorless Transparent and colorless Application Comparative Example 1 Transparent light yellow Transparent light yellow Yellow light yellow Yellow deepening Application Comparative Example 2 Transparent light yellow Transparent light yellow Yellow deepening Yellow deepening Application Comparative Example 3 Transparent light yellow Transparent light yellow Yellow light yellow Yellow deepening Application Comparative Example 4 Transparent light yellow Transparent light yellow Yellow deepening Yellow deepening Application Comparative Example 5 Transparent and colorless Transparent and colorless Transparent and colorless Transparent and colorless

[0105] As can be seen from the stability in Table 4, the applications of honokiol and magnolol in Comparative Examples 1-4 showed light yellow discoloration on the first day, while no discoloration occurred in Examples 1-5. This is because honokiol and magnolol are poorly soluble and the dissolution process requires heating, which has an impact on the stability of honokiol and magnolol in the product. However, in the present invention, the melting point regulator can make honokiol and magnolol become liquid at room temperature, which is not only beneficial to subsequent encapsulation but also beneficial to adding the product at low temperature, avoiding the yellowing caused by high-temperature dissolution.

[0106] In addition, as time goes by, the stability comparison between the 1st day and the 28th day is as Figure 3 shown. The yellowing of Comparative Examples 1-4 deepened, while the Examples remained transparent and did not turn yellow during the stability follow-up. This is because the inclusion body has a protective effect on the honokiol and magnolol encapsulated inside.

[0107] II. Oil Control Effect Test

[0108] Test Subjects: People with oily scalps aged 20-40 years old. 50 subjects were randomly divided into five groups, with 10 people in each group. No other hair products could be used during the test period. Each subject voluntarily participated in the trial and signed an informed consent form.

[0109] Test Method: The Examples and Comparative Examples were tested on half of the head, that is, the right side used the Example application and the left side used the Comparative Example application. Before the test, the subjects needed to wash their hair with a blank shampoo of the composition without the oil control effect for 1 week during the washout period. The subjects used it once every 2 days for 8 consecutive times, and the usage amount for half of the head each time was 10 ml. The hair washing process was carried out by the same hair care expert for half of the head cleaning of the subjects.

[0110] Grouping of Product Use: The Examples 1-5 and Comparative Examples 1-5 were blindly tested and numbered as HP1R, HP2R, HP3R, HP4R, HP5R, HP1L, HP2L, HP3L, HP4L, HP5L respectively.

[0111] The first group of subjects used HP1R (Example 1) on the right side of the head and HP1L (Comparative Example 1) on the left side; the second group of subjects used HP2R (Example 2) on the right side of the head and HP2L (Comparative Example 2) on the left side; the third group of subjects used HP3R (Example 3) on the right side of the head and HP3L (Comparative Example 3) on the left side; the fourth group of subjects used HP4R (Example 4) on the right side of the head and HP4L (Comparative Example 4) on the left side; the fifth group of subjects used HP5R (Example 5) on the right side of the head and HP5L (Comparative Example 5) on the left side.

[0112] Evaluation of oil control effect:

[0113] Determination of initial sebum secretion: The subjects were washed with a blank shampoo for 1 week. After the last wash, a specific area of 1.5 cm * 1.5 cm was shaved on each side of the top of the head symmetrically. Two days later, before the test wash, CK was used to measure the initial value of sebum content on the top of the head.

[0114] Determination of sebum secretion after using the product: The results were tracked once a week. Before the measurement wash (i.e., the 3rd wash and the 7th wash), the selected specific area was shaved, and CK was used to measure the sebum secretion on the scalp the day after the 4th wash and the 8th wash.

[0115] Change rate of scalp sebum secretion (%) = (sebum secretion after use - sebum secretion before use) / sebum secretion before use × 100%.

[0116] The results are shown in Table 5 below.

[0117] Table 5 Evaluation results of oil control efficacy of application examples and application comparative examples of oil control shampoo

[0118]

[0119]

[0120] It can be seen from Table 5 that the oil control effect of the oil control composition inclusion of the present invention used in shampoo is better than that of the unencapsulated components, and far better than that of the water-soluble oil control components used in shampoo.

[0121] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
