Description

Technical Field

[0001] The present invention relates to the field of daily chemicals, and in particular to a hair care composition and application thereof. Background Art

[0002] With the market trend of rising consumption levels and the rise of the appearance economy, consumers' demand for scalp care products has increased. With the rise and growth of a new generation of consumer groups, the popularity of "self-pleasing consumption" has increased, and it has become a key word for many young people. Influenced by this, more and more people are paying more attention to the investment in refined washing and care, which has also received high attention from consumers, and its market growth rate is also accelerating. On the other hand, due to people's frequent use of perming and dyeing products, as well as work and life pressure, irregular work and rest, and changes in eating habits, a series of problems brought about by a fast-paced life are indirectly accelerating the deterioration of the hair and scalp environment. Dry hair, hair loss, strong oil secretion, and dandruff have become the "top priority" that plagues contemporary young people.

[0003] There are various hair conditioners on the market, such as hair essence, hair conditioner, hair mask, hair mold, hair essence, hair essence cream, hair spa, hair oil, hair essence, etc. The hair conditioners currently used have the following disadvantages: (1) There is no significant improvement in hair quality; (2) The scalp is prone to itching and even inflammation. People with strong sebum secretion feel that their hair is greasy and difficult to wash, and dandruff cannot be effectively removed; (3) Some sensitive people experience symptoms such as hair loss, premature graying, hair damage and degeneration. Moreover, they often only treat the symptoms but not the root cause. For example, hair oil only physically reduces static electricity and friction between hair, but cannot fundamentally improve the condition of hair. And hair care products often emphasize the cleaning and soothing effects, but ignore the scalp barrier problem.

[0004] Therefore, there is an urgent need for a hair care composition with multiple functions. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a hair care composition and its application which can resist bacteria, reduce inflammation, improve scalp environment, strengthen hair and prevent hair loss.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a hair care composition, comprising the following components in parts by weight: 2-5 parts of cedarwood essential oil, 2-5 parts of bergamot essential oil, 0.5-1 part of cypress essential oil, 1-2 parts of eucalyptus essential oil, and 1-2 parts of lavender essential oil.

[0007] In some embodiments, the mass ratio of the cedarwood essential oil, cypress essential oil and eucalyptus essential oil is cedarwood essential oil: cypress essential oil: eucalyptus essential oil = 3-4: 0.6-0.8: 1.3-1.7.

[0008] In some embodiments, the cedarwood essential oil includes the following components in parts by weight: 26-30 parts of cedarol, 24-28 parts of cedrene, 15-17.5 parts of α-longifolene, 4.5-6.5 parts of B-cedrene, and 0.1-0.5 parts of longifolene.

[0009] In some embodiments, the cedar essential oil includes the following components in parts by weight: 10-14 parts of α-pinene, 9-14 parts of ocimene, 2-5 parts of limonene, 2-5 parts of cedarwood, 1.5-4 parts of linalyl propionate, 1.5-3.5 parts of terpineol-4, 1-5 parts of terpineol acetate, 0.5-3 parts of linalool, 0.1-3 parts of B-cedrene, and 0.01-0.1 parts of L-carvone.

[0010] In some embodiments, the eucalyptus essential oil includes the following components in parts by weight: 75-80 parts of eucalyptol, 5-9 parts of α-pinene, 4-8 parts of γ-terpinene, 1.5-3.5 parts of α-phellandrene, 1-4.5 parts of myrcene, 0.5-3.5 parts of β-pinene, and 0.01-1.5 parts of L-carvone.

[0011] In a second aspect, the present disclosure provides use of the hair care composition in hair care cosmetics.

[0012] In a third aspect, the present disclosure provides a hair care cosmetic comprising the hair care composition.

[0013] In some embodiments, the weight of the hair care composition is 1-10 wt % of the weight of the hair care cosmetic.

[0014] In some embodiments, the hair care cosmetic is a rinse-off cosmetic or a leave-on cosmetic.

[0015] In some embodiments, the hair care cosmetic is at least one of shampoo, conditioner, hair mask, hair oil, and hair essence.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention adds cedarwood essential oil, cypress essential oil and eucalyptus essential oil to the hair care combination, and the three have a synergistic effect, which effectively improves the antibacterial, anti-inflammatory, scalp environment improvement and hair loss prevention effects of the hair care combination. In addition, the hair care combination of the present invention is all plant oil, has no toxic side effects, is not addictive, has no drug resistance, and can be used for a long time.

[0101] Table 4

[0102]

[0103]

[0104] Performance Testing

[0105] The hair care compositions of the test examples and comparative examples have the effects of increasing the moisture content of hair, improving hair frizziness, enhancing glossiness, and strengthening hair and preventing hair breakage. The comprehensive performance of each example was comprehensively evaluated by using the methods of sensory evaluation by volunteers and hair bundle testing.

[0106] (1) Volunteer test: 40 female volunteers with normal / dry hair and shoulder-length hair were selected to use two products per week. After each week, they rated the hair care oils used that week using a 10-point scale to rate the glossiness, combability, and smoothness of the hair. The average value was taken, and the higher the score, the better the performance. The test results are shown in Table 5.

[0107] Table 5

[0108]

[0109]

[0110] From the experimental results in Table 5, it can be seen that the glossiness, combing properties and smoothness of Examples 1-10 are better than those of the comparative example, and the effects of Examples 7-9 are the best, indicating that the examples have good effects of enhancing the moisture content of hair, reducing frizziness and caring for hair, and at the same time indicating that there is a synergistic effect between cedarwood essential oil, cypress essential oil and eucalyptus essential oil.

[0111] (2) Instrument testing: combability, anti-hair breakage, glossiness, moisturizing

[0112] The combing property test of the hair care compositions provided in Examples 1-10 and Comparative Examples 1-4 was conducted, and the specific steps were as follows: 14 test hair bundles were soaked in 10% SLES solution for half an hour, and then dried naturally overnight under laboratory conditions. The combing work value of the hair bundles before using the hair care essential oil composition was tested using a hair tester as a control value. The hair care compositions of Examples 1-10 and Comparative Examples 1-4 were evenly applied to each test hair bundle and massaged for 2 minutes. After the test hair bundles were placed in a laboratory environment for 10 minutes, the wet hair combing work was tested using a hair tester. The test hair bundles were dried and tested using a hair tester, and the hair gloss, dry hair combing work and tensile strength were tested in sequence. The test results are shown in Table 6.
