Description

Technical Field

[0001] The present invention belongs to the technical field of hair care, and relates to an oil-control composition and a preparation method thereof. Background Art

[0002] Changes in modern lifestyles, such as high-fat diets, increased stress, hair dyeing and perming, etc., have led to the increasingly common problem of scalp oil imbalance. With consumers' increasing emphasis on personal image management and attention to scalp health, there are an endless stream of hair care products for scalp oil. At present, the oil-control products mainly include shampoo and hair care essential oil. The former achieves the oil-control effect by cleaning and conditioning the scalp, and the latter inhibits oil secretion by the penetration of active ingredients into hair follicles. However, at present, the washing and hair care oil-control products either achieve oil removal and control through surfactants, which are prone to over-cleaning and damage to the scalp barrier, or reduce oil secretion by introducing active ingredients. If the control of the active concentration is unbalanced, it is easy to stimulate the scalp; or add prebiotics to assist in conditioning the scalp microenvironment to achieve oil control, with high costs and the prebiotics are prone to inactivation, etc., and it is impossible to achieve effective oil control and scalp maintenance. Summary of the Invention

[0003] The purpose of the present invention is to provide an oil-control composition and a preparation method thereof. The present invention inhibits oil secretion and avoids oil accumulation through the compounding of Phellodendron amurense-Radix Scutellariae-Folium Sophorae Flavescentis-Folium Nelumbinis extracts; further regulates the scalp microecology through the compounding of Phellodendron amurense-Radix Rehmanniae-Folium Nelumbinis-Herba Artemisiae Capillaris extracts, thereby astringing pores and reducing the expansion of oil secretion channels; at the same time, encapsulated salicylic acid is introduced to slowly release salicylic acid during hair washing or hair strand care to adsorb the excess sebum that overflows, and nano-emulsified tea tree essential oil, with its antioxidant effect, improves the stability of other components and enhances the transdermal absorption of other raw materials; each component synergistically exerts the oil-control effect.

[0008] Step X2: Mix hydroxypropyl chitosan, lotus leaf extract, and deionized water to obtain a colloidal liquid;

[0009] Step X3: Add the salicylic acid solution to the colloidal liquid and disperse it to obtain an emulsion;

[0010] Step X4: Subject the emulsion to microcapsule spray drying to obtain encapsulated salicylic acid.

[0011] Further, the ethanol solution in Step X1 is a 34-38 wt% ethanol solution; the content of salicylic acid in the salicylic acid solution is 1.1-1.3 wt%; the temperature increase refers to increasing the temperature to 60-64 °C.

[0012] Further, the mass ratio of hydroxypropyl chitosan, lotus leaf extract, and deionized water in Step X2 is 1:0.4-0.6:44-46.

[0013] Further, the mixing in Step X2 refers to heating the deionized water to 40-42 °C, adding hydroxypropyl chitosan, stirring at a speed of 500-700 rpm for 28-32 min, then adding the lotus leaf extract, and continuing to stir for 14-18 min before cooling to room temperature.

[0014] Further, the mass ratio of the salicylic acid solution to the colloidal liquid in Step X3 is 1:3.8-4.2; the dispersion refers to stirring at a speed of 9000-11000 rpm for 20-30 min at room temperature.

[0015] Further, the parameters of the microcapsule spray drying in Step X4 are as follows: the inlet air temperature is 103-107 °C, the outlet air temperature is 58-62 °C, the atomization pressure is 0.7-0.9 MPa, and the feeding speed is 8-10 mL / min.

[0016] Further, the nano-emulsified tea tree essential oil is obtained by stirring the tea tree essential oil at a speed of 10000-12000 rpm for 4-6 min, setting the pressure of the high-pressure microfluidic treatment to 60-100 MPa, the flow rate to 40-60 mL / min, and treating it 3 times.

[0021] Advantages of the present invention:

[0022] (1) The present invention introduces Artemisia capillaris extract, Phellodendron amurense extract, Scutellaria baicalensis extract, Rehmannia glutinosa extract, Sophora flavescens extract, and Nelumbo nucifera leaf extract, and the oil control effect is exerted synergistically by various traditional Chinese medicine components. Among them, the berberine component in the Phellodendron amurense extract can also inhibit the growth of bacteria and fungi, further reducing the problems of oil secretion and pore blockage; the Scutellaria baicalensis extract is rich in flavonoids such as baicalin, which can reduce the overactivity of sebaceous glands, thereby controlling oil secretion; matrine in Sophora flavescens regulates the scalp oil secretion to avoid oil accumulation; nuciferine in Nelumbo nucifera leaf extract can inhibit the secretion of sebaceous glands, thereby reducing oil secretion; that is, through the compounding of Phellodendron amurense - Scutellaria baicalensis - Sophora flavescens - Nelumbo nucifera leaf extracts, the oil secretion is inhibited, the oil accumulation is avoided, and the oil control effect is achieved. On this basis, the Phellodendron amurense extract has the effect of clearing heat and drying dampness, promoting the qi and blood circulation of the scalp; the Rehmannia glutinosa extract can assist in nourishing the hair and improving the microecological balance of the scalp; tannin in the Nelumbo nucifera leaf extract has the effect of shrinking pores and can effectively reduce oil secretion; the Artemisia capillaris extract can inhibit or kill some pathogenic bacteria causing scalp inflammation, reduce inflammatory reactions such as itching, and thus condition the scalp microecology; that is, through the compounding of Phellodendron amurense - Rehmannia glutinosa - Nelumbo nucifera leaf - Artemisia capillaris extracts, the scalp microecology is further regulated, so as to shrink pores and reduce the expansion of oil secretion channels, and the oil control effect is exerted synergistically.

[0023] (2) The present invention introduces microencapsulated salicylic acid. Hydroxypropyl deacetylated chitosan swells into a gel in water, and at the same time adsorbs tannin in the Nelumbo nucifera leaf extract to enhance the stability of the gel structure, serving as the wall material for encapsulating low-concentration salicylic acid; salicylic acid is slowly released during shampooing or hair strand care, adsorbing the excess sebum that overflows, and the oil control effect is exerted synergistically; in addition, adding Nelumbo nucifera leaf extract to the wall material helps to improve the compatibility with other raw materials.

[0024] (3) The present invention also introduces nano-emulsified tea tree essential oil. By virtue of its antioxidant effect, the stability of other components is improved, and at the same time, the transdermal absorption of other raw materials is enhanced, further strengthening the oil control effect of the composition.

[0151] After wetting the hair, take an appropriate amount of shampoo in the palm of the hand, rub to produce foam, then evenly apply it on the head, rub for 3 minutes, and then rinse it clean with water. Use it once every morning. Observe the oiliness of the hair on the second morning after continuous shampooing for one week. It is considered significantly effective if the hair is free of grease, dry, and has no greasy feeling; it is considered effective if the hair is improved compared with before the test and the greasy feeling is not obvious; it is considered ineffective if the oiliness of the hair has no obvious change compared with before the test. The total effective rate is the ratio of the number of people given a significant effective or effective evaluation to the total number of people. After the statistics, the results are recorded as shown in Table 2 below.
