Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a composition having the dual functions of improving hair gloss and repairing scalp, as well as a preparation method and application thereof. Background Art

[0002] As people's quality of life improves, consumers' demand for hair care is also increasing. Hair is a natural, high-molecular-weight keratin fiber that covers the scalp, preventing heat loss and protecting it from damage, while also maintaining its appearance. However, daily brushing, friction, chemical treatments, high-temperature styling, UV damage, and air pollution can all cause varying degrees of hair damage. The main symptoms of hair damage include: frizzy, difficult-to-comb hair, a dull, matte appearance, reduced resilience and strength, and brittle, easily breakable hair. Because hair lacks self-repair capabilities, once damaged, it is difficult to repair itself. The scalp, the "soil" in which hair grows, directly determines its health and well-being. Therefore, daily hair care should not only focus on basic hair shaft care but also on scalp maintenance.

[0003] Therefore, it is urgent to develop a product that takes both scalp and hair care into consideration. Summary of the Invention

[0004] The present invention aims to address at least one of the technical problems existing in the aforementioned prior art. To this end, the present invention provides a composition, a preparation method, and its use. This composition not only has soothing and anti-inflammatory effects, but also forms a sebum layer on the skin surface, effectively protecting against external aggressions and effectively repairing the skin barrier, fundamentally addressing the problem of damaged scalp barriers. It also nourishes hair and regulates its glossiness.

[0005] A first aspect of the present invention provides a composition comprising the following components: squalane, ginger root oil, PPG-3 benzyl ether myristate and phenyl trimethicone.

[0006] In the composition provided by the present invention, the functions of each component are as follows:

[0007] Squalane, preferably plant-based squalane, is obtained by hydrogenating squalene, a natural olive oil source. Its molecular structure is similar to squalene in the sebum layer. Squalane is a rare chemically stable substance with good affinity for the skin. It can integrate with the body's own sebum membrane to form a natural barrier on the skin surface. It can also inhibit the peroxidation of skin lipids, effectively penetrate into the skin, and promote the proliferation of skin basal cells, thereby delaying skin aging and helping to repair damaged stratum corneum.

[0008] Ginger root oil is rich in geranyl aldehyde, eugenol, tea polyol, gingerol, zingerone, gingerdiol and other ingredients. It has excellent antioxidant and antibacterial effects. It not only has a strong scavenging ability against DPPH free radicals, ABTS free radicals, and hydroxyl free radicals, but also has a good inhibitory effect on various foodborne pathogenic fungi and bacteria.

[0009] PPG-3 benzyl ether myristate is a synthetic oil with a high refractive index. It is highly safe and non-irritating or non-sensitive. Its unique chemical structure determines its excellent skin affinity and lubricity, forming a thin and uniform film on the skin surface.

[0010] Phenyl trimethicone, also known as a "hair lightener," imparts a silky, moisturizing, and non-greasy feel to the skin and hair in the formula of this invention. It can reduce the greasiness of other ingredients in the formula of this invention and is an excellent emollient.

[0011] Specifically, the refractive index of oil refers to the degree of light deflection caused by changes in the speed of light as it propagates across its surface. Based on this, the present invention uses a combination of the above-mentioned oils to control the refractive index of the oils, thereby adjusting the optical properties of the hair surface, thereby affecting the reflection and refraction of light and improving the gloss of the hair.

[0012] Specifically, the scalp barrier is composed of a "brick wall structure" formed by the stratum corneum and the sebum membrane, dermal mucopolysaccharides, mucopolysaccharides and other components. Among them, sebum is the outermost component of the skin, and its main components are: triglycerides, free fatty acids, wax esters, squalene, cholesterol esters, cholesterol and other components. It plays a vital role in the skin barrier function. Its main functions are to prevent skin moisture loss, reduce ultraviolet damage to the skin, and protect against biological invasions. Therefore, the sebum layer plays a vital role in the skin barrier function; based on this, the present invention adopts the above-mentioned compound of several oils to form a sebum layer on the skin surface, which effectively resists external invasion and plays a good role in repairing the skin barrier.

[0013] In some embodiments of the present invention, the composition comprises the following components, calculated by weight: 0.1-40 parts of squalane, 0.1-20 parts of ginger root oil, 1-50 parts of PPG-3 benzyl ether myristate, and 1-70 parts of phenyl trimethicone.

[0014] In some embodiments of the present invention, the composition comprises the following components, calculated by weight: 3-30 parts of squalane, 1-15 parts of ginger root oil, 1-45 parts of PPG-3 benzyl ether myristate, and 1-50 parts of phenyl trimethicone.

[0015] In some embodiments of the present invention, the composition comprises the following components: 15-30 parts of squalane, 7-15 parts of ginger root oil, 20-45 parts of PPG-3 benzyl ether myristate, and 30-50 parts of phenyl trimethicone.

[0016] By optimizing the appropriate amount of oil, the present invention can change the thickness and shape of the oil film formed on the hair surface, thereby affecting the reflection and refraction of light on the surface, and can increase the refractive index of the hair surface, so that more light is refracted rather than reflected, thereby making the hair present a softer and more natural luster. In addition, a more uniform and dense oil film is formed on the hair surface, which can reduce the scattering of light on the surface, improve the refraction effect of light, and thus enhance the gloss of the hair.

[0017] In general, the present invention can more effectively regulate the reflection and refraction of light on the hair surface by adopting appropriate types of oils and adjusting the dosage, thereby achieving precise control of the hair gloss.

[0018] The second aspect of the present invention provides a method for preparing the composition according to the first aspect of the present invention, comprising the following steps:

[0019] The squalane, ginger root oil, PPG-3 benzyl ether myristate and phenyl trimethicone are mixed to prepare a composition.

[0020] The third aspect of the present invention provides use of the composition described in the first aspect of the present invention in preparing a product having the effects of improving hair gloss and / or repairing the scalp.

[0021] In some embodiments of the present invention, the composition is added to the product in an amount of 0.01-10 wt %, preferably 0.1-10 wt %, and more preferably 1-10 wt %.

[0022] A fourth aspect of the present invention provides a cosmetic comprising the composition according to the first aspect of the present invention.

[0023] In some embodiments of the present invention, the content of the composition in the cosmetic is 0.01-10 wt %, preferably 0.1-10 wt %, more preferably 1-10 wt %.

[0024] In some embodiments of the present invention, the cosmetic comprises an essential oil, a cream, a shampoo, or a conditioner.

[0025] In some embodiments of the present invention, the cosmetic is selected from a cream, which includes the composition of the first aspect of the present invention, isopropyl myristate, polydimethylsiloxane, PEG-10 polydimethylsiloxane, cetearyl alcohol, glyceryl stearate, PEG-100 stearate, cetearyl glucoside, glycerin, propylene glycol, acrylates / C10-30 alkyl acrylate crosspolymer, 1,2-hexanediol, parahydroxyacetophenone, phenoxyethanol, aminomethyl propanol and water.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention provides a composition comprising squalane, ginger root oil, PPG-3 benzyl ether myristate and phenyl trimethicone through the selection of specific oils. The components cooperate with each other, which can not only accurately control the glossiness of hair, enhance the glossiness of hair and maintain hair, but also has soothing and anti-inflammatory effects. It can also form a sebum layer on the skin surface to effectively resist external aggression, play an excellent role in repairing the skin barrier, and fundamentally solve the problem of damaged skin barrier. The composition of the present invention can achieve dual care for the scalp and hair. BRIEF DESCRIPTION OF THE DRAWINGS

[0177] Comparing Application Comparative Examples 10-13 with Application Example 2, when the raw materials plant squalane, ginger root oil, PPG-3 benzyl ether myristate, and phenyl trimethicone are replaced with raw materials with similar functions, the brightening effect is reduced, indicating that the components of the composition of the present invention have a good synergistic effect, and the absence of any component will lead to a significant decrease in the effect.

[0178] 2. Scalp status change test

[0179] Samples to be tested: cream samples provided in Application Example 2 and Application Comparative Example 1.

[0180] Testing method: Apply an appropriate amount of cream to the red scalp and massage until absorbed. Take photos of the scalp before applying the cream and 2 hours after applying the cream to observe the actual repair effect of the sample.

[0181] The results are as follows Figure 1 and Figure 2 As shown. Figure 1 It can be seen that after 2 hours of application of the cream of Example 2, the redness is basically eliminated; Figure 2 It can be seen that after 2 hours of application of the cream of Comparative Example 1, the redness phenomenon was not significantly improved.

[0182] 3. Transepidermal water loss test

[0183] Samples to be tested: cream samples provided in Application Examples 1-6 and Comparative Examples 1-13.

[0184] The specific test method is as follows:

[0185] A total of 190 subjects, including 95 females and 95 males, aged 20-40 years old (mean age 28 years old), were randomly divided into groups of 10 volunteers each, and used each group of creams for 4 weeks;

[0186] The subjects sat quietly for 30 minutes at a temperature of 21±1°C and a humidity of 50±10%. The transepidermal water loss rate was measured 5 cm from the forehead. After the test, the subjects took the sample home and used it after each shampooing. The shampooing frequency was: 3 times / week. After 28 days of use, the transepidermal water loss rate was measured at the same location under the same conditions.

[0187] During the test, the hair should be washed with base shampoo. The hair should be washed one day before the test. The test should be performed using Biox's Aquaflux Skin Water Loss Tester. The test should be repeated 5 times and the average value should be recorded.

[0188] The results are shown in Table 4.

[0189] Table 4

[0190]

[0191]

[0192] It's understood that skin moisture content is a key indicator of skin barrier function. Impaired skin barrier function increases transepidermal water loss (TEWL). Table 4 shows that the creams of Examples 1-6 significantly reduced TEWL after 28 days of use, demonstrating significant improvement in scalp barrier function.

[0193] In summary, the composition provided by the present invention and the cosmetics containing the same have outstanding effects of repairing the scalp barrier, soothing and anti-inflammatory, protecting hair, and improving hair gloss. This is because the four oils in the composition provided by the present invention have a synergistic effect, which can accurately control the refractive index and distribution of the oils to regulate the gloss of the hair. It can also form a sebum layer on the skin surface, effectively resisting external aggression and playing a good role in repairing the skin barrier.

[0194] It is understood that oils form an oily film on the hair and scalp, and distribution refers to the differences in the oily film formed by different oils in the composition of the present invention.

[0195] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments.
