Description

Three-layer hair care composition and preparation method and application thereof

Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to a three-layer hair care composition and a preparation method and application thereof.

Background

In real life, people pay more and more attention to appearance and pursue fashion, and the whole image and comfort of people can be obviously improved by having smooth, smooth and glossy hair and scalp, however, the hair and the scalp are usually damaged by various external factors, including hair washing, heating, combing, sizing, perm, dyeing, and exposure to various natural environments such as ultraviolet rays, dust and the like, and the factors are easy to cause protein loss, hair scale abrasion and scalp moisture loss in the hair, so that the hair is always in dry, rough and dull states, and the scalp is in dry, tight and itching unhealthy states.

At present, a plurality of leave-on hair care products are developed on the market to solve the problems of dry hair and dry scalp, most of the products adopt natural vegetable oil or cyclopentadimethylsiloxane (D5) as a hair care base material, the natural vegetable oil is independently used for conditioning the hair of people, the hair can be quickly absorbed by the hair, but the hair care base material has insufficient lubricity, brings unwelcome sticky feeling to users, and is easy to rancidity. In addition, D5, used alone, is not readily rancid and off-flavored, but is not absorbed by the hair, and is used as a volatile silicone oil in hair care to provide a silky feel, but leaves the hair with an unnatural shine and an easily absorbed artifact.

CN107184430A discloses a hair care composition containing no silicone oil, which contains natural vegetable oil, natural essential oil, sunscreen component, butyl hydroxy toluene, phenoxyethanol and essence. The hair care composition containing no silicone oil has mild property, can improve the smoothness of hair by more than 35 percent after being used, has the ultraviolet blocking rate of more than 50 percent on UVB area, and reduces the scalp percutaneous water loss rate by more than 35 percent. But the natural vegetable oil and essential oil contained in the hair conditioner can cause the hair to have very serious sticky feeling, and the use experience is poor.

Therefore, the development of a hair care composition which can effectively solve the problems of dry hair, rough hair, dull hair, dry scalp, tight hair, pruritus and the like and can enable the hair to keep a smooth and glossy state for a longer time is a very big challenge in the field of makeup and make-up at present.

The preparation method is the same as that of example 1.

TABLE 3

And (3) performance testing:

two commercial products, namely commercial product a and commercial product B, were used in the following two test procedures, with specific product names, manufacturers and brands as follows:

commercially available sample a was: opal florescent essential oil (luxurious essence) (purchased from warship, beiya kyoto, inc., under the designation 74S 50020220503); commercial sample B was: opal florescent essential oil (rose treasure) (purchased from warship, beiya kyoto, inc., mark 74S 80120220805).

1. Dynamic combing test of hair tresses:

(1) testing an instrument: a hair softness detector SK-3A.

(2) The test principle is as follows: the sensory quantification process is realized through constant pressure and automatic operation, the combing data are processed results, the lower the numerical value is, the better the combing performance is represented, and the more flexible the hair is. The hair flexibility detector used in the experiment mainly comprises a shower nozzle, a displacement meter, a loading unit, an electrostatic sensor and other parts.

(3) The test method comprises the following steps: the hair Combing effects of the examples, comparative examples, commercially available samples A and commercially available samples B of the present invention were evaluated by applying the same 19 prepared hair tresses to a dynamic Combing Tester (Comgang Tester SK-3A, Techno Hashimoto Co.) and applying the products of examples, comparative examples, commercially available samples A and commercially available samples B to the hair tresses using dry hair tresses without any hair care products as a blank, and the results are shown in Table 4:

TABLE 4

As can be seen from the data in table 4: the three-layer hair care compositions prepared in examples 1-13, when applied to hair switches, exhibited substantially lower combing performance than both the blank and commercial samples, indicating that the hair care compositions prepared in the examples significantly improved the dry and rough hair and improved hair smoothness.

The hair care compositions of examples 6-9 of the present invention, when applied to the hair bundle, showed significantly lower dry combing performance than example 1. This is because, compared to example 1, the hair care compositions of examples 6-9 have a liquid upper layer comprising only a single vegetable base oil, while the liquid upper layer of example 1 comprises four vegetable base oils, which can cooperate with each other to achieve synergistic effects, so that the softness of hair strands is significantly improved, and the problems of dry and rough hair are significantly improved.

The hair care compositions prepared in examples 10-13 of the present invention, when applied to the hair bundle, also showed significantly lower dry combing performance than that of example 1. The reason is that the liquid upper layer in example 1 comprises four kinds of vegetable base oil, the four kinds of vegetable base oil can be matched with each other and have synergistic effect, and compared with example 1, the liquid upper layers in examples 10 to 13 lack one kind of vegetable base oil, and the improvement effect on the softness of hair bundles is obviously inferior to that of example 1, which indicates that the four kinds of vegetable oil must exist simultaneously, are matched with each other and lack one, and only the four kinds of vegetable oil are reasonably compounded for use, so that the softness of hair bundles can be obviously improved, and the problems of dry hair and rough hair can be obviously improved.

The hair care compositions of comparative examples 1 to 3 according to the present invention, which comprise only two of the three layers of the liquid upper layer, the liquid intermediate layer and the liquid lower layer, lack the liquid intermediate layer in the hair care composition of comparative example 1, lack the liquid upper layer in the hair care composition of comparative example 2, lack the liquid lower layer in the hair care composition of comparative example 3, produced hair care compositions which, after being applied to hair strands, had a significantly lower reduction in the combing performance data than in any of the examples. The reason is that only by compounding the upper liquid layer, the middle liquid layer and the lower liquid layer, the easy absorbability of the natural vegetable oil, the smoothness of the siloxane and the moisturizing performance of the polyol can be well combined together, and the problems of dry and rough hair can be effectively solved.

2. Scalp moisturizing test:

(1) and (4) testing standard: in the test, the hair care compositions obtained in the examples and the comparative examples, a commercially available sample A and a commercially available sample B are subjected to moisturizing efficacy test according to the light industry standard 'cosmetic moisturizing efficacy evaluation guideline';

(2) the test principle is as follows: the capacitance method is used for measuring the moisture content of the human skin horny layer, and is based on the obvious difference of dielectric constants of water and other substances, the capacitance values of the measured skin are different according to the moisture content of the human skin horny layer, and the parameters can represent the moisture content of the scalp.

(3) The test method comprises the following steps: selecting 50 subjects who are dyed with perm substance, wherein all the subjects have no history of scalp allergy or scalp diseases, the tested parts have no abnormality, all the subjects are female and are 21-45 years old, the whole testing process is carried out in a constant temperature and humidity laboratory, the room temperature is 20-22 ℃, and the humidity is 40-60%; skin moisture content was measured using Corneometer CM825 (Courage + Khazaka, germany, available from hokyo gold sail), 19 sites were selected on the back side of the heads of 50 subjects, each site was 5CM × 5CM, hair care compositions prepared according to examples and comparative examples of the present invention and commercially available products were applied to each site in sequence, one site was left without any hair care product as a blank, and the higher the value, the higher the moisture content of the stratum corneum;

before testing, subjects wash hair with the same shampoo, blow the hair, keep a certain posture for 30min, respectively coat the samples of examples 1-13 and comparative examples 1-3, the samples A and B on the market on the test part, set blank control areas, and respectively set the test time points of (0h) before coating, 1h and 2h after coating, wherein the sample coating amount is 2.0 +/-0.1 mg/cm²。

The specific test results are shown in table 5.

TABLE 5

As can be seen from Table 5, the scalp moisture content was increased compared to the blank control group after applying a certain amount of the hair care compositions or hair oils of examples 1 to 5 of the present invention, comparative examples 1 to 3 and commercially available A, B.

Compared with example 1, the hair care compositions prepared in examples 6-9 of the present invention had a scalp moisture content significantly lower than that of example 1 after being applied to the scalp. This is because, compared to example 1, the hair care compositions of examples 6-9 have a liquid upper layer comprising only a single vegetable base oil, while the liquid upper layer of example 1 comprises four vegetable base oils, which can be matched with each other to synergistically enhance the efficacy, and are reasonably combined with the liquid middle layer and the liquid lower layer, so that the moisture retaining components brought into the scalp by the liquid lower layer can be well prevented from running off, the moisture of the scalp skin can be retained, and the moisture content of the scalp can be significantly increased.

Compared with example 1, the hair care compositions prepared in examples 10-13 of the present invention applied to the scalp had a scalp moisture content significantly lower than that of example 1. The reason is that the upper liquid layer in example 1 includes four kinds of vegetable base oil, which can cooperate with each other to achieve synergistic effect, but compared with example 1, the upper liquid layers in examples 10 to 13 lack one kind of vegetable base oil, and the effect of improving the moisture content of the scalp is obviously inferior to that of example 1, which indicates that the four kinds of vegetable oil must exist simultaneously, cooperate with each other, and lack one, and only the four kinds of vegetable oil are reasonably compounded to prevent the moisture retention component brought into the scalp from losing from the lower liquid layer, so that the moisture content of the scalp is retained, that is, the moisture content of the scalp is obviously improved.

The hair care compositions of comparative examples 1 to 3 according to the present invention, which comprise only two of the three layers of the liquid upper layer, the liquid intermediate layer and the liquid lower layer, were lacking in the liquid intermediate layer in the hair care composition of comparative example 1, were lacking in the liquid upper layer in the hair care composition of comparative example 2, and were lacking in the liquid lower layer in the hair care composition of comparative example 3, produced hair care compositions having a scalp skin moisture content significantly lower than that of any of the examples. The reason is that the easy absorbability of the natural vegetable oil, the smoothness of the siloxane and the moisturizing performance of the polyalcohol can be well combined only by compounding the upper liquid layer, the middle liquid layer and the lower liquid layer, so that the effects of moisturizing and nourishing the scalp can be achieved.

In conclusion, the three-layer hair care composition provided by the invention adopts the combination of the natural vegetable oil, the siloxane and the polyalcohol, so that the absorbability of the natural vegetable oil, the smoothness of the siloxane and the moisturizing performance of the polyalcohol are well combined together, four kinds of natural vegetable oil are screened out, and after the four kinds of natural vegetable oil are compounded with the siloxane and the polyalcohol according to a certain proportion, the problems of dry hair, rough hair, dull hair, dry scalp, tightness, pruritus and the like are effectively solved, the hair is kept to be smooth for a longer time, and the scalp is kept to be moist and comfortable for a long time, so that the three-layer hair care composition has wide application prospect and market value.

The applicant declares that the present invention illustrates the detailed structural features of the present invention through the above embodiments, but the present invention is not limited to the above detailed structural features, that is, it does not mean that the present invention must be implemented depending on the above detailed structural features. It should be understood by those skilled in the art that any modifications of the present invention, equivalent substitutions of selected components of the present invention, additions of auxiliary components, selection of specific modes, etc., are within the scope and disclosure of the present invention.
