[0002] Hair is composed of high-molecular keratin fibers, which play a role in protecting and regulating the scalp. Light, hot hair, acid, alkali, oxidants, and reducing agents can all destroy the structure of keratin fibers. In daily life, perming, dyeing, straightening, curling, and hair dryers can cause varying degrees of damage to the hair, causing the hair scales on the hair cuticle to curl up and become damaged, making the hair frizzy, difficult to comb, and dull. Hair repair has become an important aspect of hair care.

[0003] Consumers have an increasing demand for instant hair repair. In the current instant repair technology, damaged hair is repaired by providing leave-in products such as hair oil or single / double-layer hair spray emulsion. After research and testing, it was found that the existing double-layer hair spray emulsion has incomplete emulsification of the oil phase and the water phase of the system, resulting in unsatisfactory high and low temperature stability, especially low temperature stability of the product. Patent CN202311812839.0 discloses a double-layer spray composition. This technical solution adopts an oil-in-water system to solve the high and low temperature stability of the system. However, there is still a gap in solving the problem of low-temperature freezing stability of double-layer hair care emulsions of oil-in-water system. Summary of the invention

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific embodiments.

[0027] The following are non-limiting examples of shampoo compositions of the present invention. These examples are given for illustrative purposes only and are not to be construed as limitations of the present invention, as many variations may be made without departing from the spirit and scope of the present invention. In these examples, all concentrations are by weight unless otherwise indicated. The term "minor substances" used refers to those optional substances, such as preservatives, viscosity modifiers, pH modifiers, fragrances, pigments, etc., and the selection of these minor substances will vary with the physical and chemical properties of the specific ingredients selected to prepare the present invention.

[0028] Example

[0029] A water-in-oil double-layer hair care spray emulsion composition, embodiments 1 to 5 are shown in Table 1:

[0030] Table 1

[0031]

[0032] Preparation process of Example 1-5: Mix phase A and phase B materials separately, heat to 75-85°C, pour phase B into phase A and homogenize for 5 minutes, cool to 48°C and then discharge, and after standing, obtain a double-layer hair care lotion with a milky white upper layer and a transparent lower layer.

[0033] Comparative Example 1

[0034] The difference between Comparative Example 1 and Example 1 is that the auxiliary emulsifier in phase A is omitted, the amount of the main emulsifier cetyl PEG / PPG-10 / 1 polydimethylsiloxane is increased to 1.3 parts, and the rest is the same as Example 1.

[0035] Comparative Example 2

[0036] The difference between Comparative Example 2 and Example 1 is that the main emulsifier cetyl PEG / PPG-10 / 1 polydimethylsiloxane in phase A is omitted, and the amount is added to the auxiliary emulsifier, and the rest is the same as Example 1.

[0037] Comparative Example 3

[0038] The difference between Comparative Example 3 and Example 1 is that the silicone conditioning agent in Example 1 is changed, and the bis(C13-15 alkoxy)PG-amino-terminated polydimethylsiloxane is replaced by trifluoropropyl polydimethylsiloxane, and the rest is the same as Example 1.

[0039] Comparative Example 4

[0040] The difference between Comparative Example 4 and Example 1 is that the oil in Example 1 is changed, and isononyl isononanoate is replaced by isododecane, and the rest is the same as Example 1.

[0041] Commercially available comparison

[0042] Two commercially available double-layer hair spray products (water-in-oil system) were used as comparative examples, namely, commercial comparative example A and commercial comparative example B.

[0043] Effect Example 1

[0044] Stability test:

[0045] Examples 1-5 and Comparative Examples 1-2 were placed at different temperatures (48°C, -20°C) for high and low temperature stability tests, and the appearance of the samples after returning to room temperature was recorded every week and rated as excellent, medium, or poor. The test period was 42 days.

[0046] Stability assessment criteria:

[0047] Excellent: The upper emulsion is uniform, the lower layer is clear and uniform, without flocculation or oil separation;

[0048] Middle: The upper emulsion has slight oil separation and stratification, and slight flocculation;

[0049] Poor: The upper emulsion is severely demulsified and stratified, uneven, and the lower layer is turbid.

[0050] The test results are shown in Table 2 and Table 3.

[0051] Table 2

[0052]

[0053]

[0054] Table 3

[0055]

[0056] As can be seen from Tables 2 and 3, the high and low temperature stability of Examples 1-5 are better than those of Comparative Examples 1-4 and commercially available Comparative Examples A and B. This is because compared with Examples 1-5, the components or proportions of the emulsifiers, silicone conditioning agents or oils in Comparative Examples 1-4 have changed, thereby affecting the stability of the system.

[0057] In summary, it is shown that it is crucial to reasonably set the specific ingredients and proportions of emulsifiers, silicone conditioning agents, oils and fats in the present invention. The composition of the present invention is an incompletely emulsified dosage form, which is different from other completely emulsified dosage forms. It is not only the selection of emulsifiers, but also the matching of emulsified ingredients and the control of a specific ratio range to achieve a stable balance point of the formula combination system.

[0058] Effect Example 2

[0059] Examples 1-5 were manually shaken at the same temperature (25° C.) with the same intensity to mix, and the shaking time, the time to maintain a uniform state after shaking, and the time to restore the double layer were recorded.

[0060] The results are shown in Table 4.

[0061] Table 4

[0062]

[0063] As can be seen from Table 4, in Example 1 and Example 2, the weight ratio of the emulsifier, silicone conditioning agent, and oil is preferably controlled in the range of (0.8-1.5): (0.5-1): (4-7), and can be mixed evenly in no more than 10 seconds. After stopping shaking, the uniform state can be maintained within 10 minutes, and the double-layer structure can be reformed within no more than 15 minutes, ensuring that consumers have enough time to use the product before it is layered again.

[0064] Effect Example 3

[0065] Hair bundle dynamic combing test:

[0066] Test equipment: Instron 2343 electronic universal material testing machine, hair comb fixture (stand), hair bundle fixture (suspension), Instron LLC

[0067] Test principle: The combing test of hair bundles is to dynamically simulate the process of people combing hair with a comb through a combing test instrument when the hair bundle is dry or wet, and record the change of friction resistance during the combing process to characterize the smoothness of hair after using the product. In this test, the hair bundle passes through the comb on the combing test instrument at the same speed, and the combing force (or combing work) is calculated based on the data.

[0068] Test method: The treated hair bundle was fixed at the test position of a universal material testing machine (Instron 2343Q5353, Instron LLC). A dry hair bundle without any product was used as a blank control. The products of Examples 1-2 of the present invention and Comparative Examples A and B available on the market were applied to the hair bundle to evaluate the effects of the Examples of the present invention and the comparative examples available on the combing properties of the hair. The specific test results are shown in the following table.

[0069] Test parameters:

[0070] 1. Combing force: average pulling force throughout the process, externally manifested as combing properties (including smoothness and tangling);

[0071] 2. Entanglement force: the average tension of the entanglement section during the stretching process, which is manifested as a sense of entanglement;

[0072] 3. Remaining %: The ratio of the test data after the sample is used to the test data before use. The lower the remaining value, the better the improvement effect.

[0073] The results are shown in Table 5.

[0074] Table 5

[0075]

[0076] It can be seen from the table that the residual values ​​of the combing force and the entanglement force of Examples 1-2 of the present invention are lower than those of the commercial comparative examples, indicating that the composition of the present invention is superior to other commercial comparative examples in improving the combing performance of dry hair and enhancing the smoothness of hair.

[0077] The above disclosure is only the preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
