Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to an alcohol agent that forms frost when in contact with water and application of the alcohol agent in cosmetics. Background Art

[0002] Ester-soluble and alcohol-soluble active ingredients, such as 4-hexylresorcinol and 4-tert-butylcyclohexanol, are usually formulated into essence oils or cream preparations during use because they are insoluble in water. However, these active ingredients in the cream are easily affected by pH, oxygen, light, and heat, causing the product to change color and lose biological activity. Essence oils are greasy on the skin and easily cause acne, so they are not widely used and have certain limitations. Therefore, some ester-soluble and alcohol-soluble active ingredients on the market currently have great limitations in use and are not fully applied. Based on this, the present invention proposes an alcohol agent that forms frost when in contact with water and its application in cosmetics. Summary of the invention

[0003] In view of the above problems, the present invention provides an alcohol agent that forms frost when in contact with water and application of the alcohol agent in cosmetics to solve the problems of the background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: An alcohol agent that forms frost when in contact with water, comprising the following components by total weight: (a) 5 to 35 parts of fatty alcohol; (b) 0.5-10 parts of a surfactant; (c) 40-94 parts of polyols; (d) 0.5-15 parts of fat.

[0005] The alcohol agent of the present invention is a transparent product in appearance, and can be formed into frost by shaking it evenly when it meets water at room temperature. The frost refers to a dispersion formed under the co-existence of oil, water and surfactant. The alcohol agent of the present invention will produce a warm feeling when used, and can be formed into frost by shaking it evenly or applying it when it meets water.

[0006] In some embodiments, the fatty alcohol includes at least one of lauryl alcohol and myristyl alcohol.

[0007] In some embodiments, the surfactant includes at least one of a polyglycerol ester emulsifier, a polyether emulsifier, a PEG emulsifier and a cationic surfactant.

[0008] In some embodiments, the polyglycerol ester emulsifier includes at least one of polyglyceryl-10 oleate, polyglyceryl-2 laurate and polyglyceryl-10 laurate.

[0009] In some embodiments, the cationic surfactant includes at least one of cetrimonium chloride, octadecyltrimethylammonium chloride, hexadecyltrimethylammonium chloride and behenyltrimethylammonium chloride.

[0010] In some embodiments, the polyol includes at least one of propylene glycol, butylene glycol, ethanol and pentylene glycol.

[0011] In some embodiments, the oil includes at least one of cyclopentasiloxane, propylene glycol laurate, ethylhexyl palmitate, 26% white oil and DC345.

[0012] The DC345 is a mixture of polydimethylcyclosiloxanes, the main components of which are cyclopentasiloxane and cyclohexasiloxane.

[0013] The present invention also provides the use of the alcohol agent that forms frost when in contact with water in the preparation of cosmetics, wherein the cosmetics include skin care products and hair care products.

[0014] The present invention also provides a liquid hair mask, comprising the alcohol agent as described above and a common base for external hair care product formulations, wherein the alcohol agent comprises 5-35 parts of fatty alcohol, 0.5-10 parts of surfactant, 40-94 parts of polyol and 0.5-15 parts of oil, and the common base for external hair care product formulations comprises 0.3-0.6 parts of polyquaternium-11, 0.1-0.4 parts of menthol, 8-11 parts of anhydrous ethanol, 0.3-0.7 parts of phenoxyethanol and 0.5-2 parts of essence.

[0015] In some embodiments, the liquid hair mask comprises the following components in percentage by weight: Myristyl alcohol 5-20%, Octadecyltrimethylammonium chloride 1-2%, Hexadecyltrimethylammonium chloride 1-1.3%, Behenyltrimethylammonium chloride 1-1.5%, Cyclopentasiloxane 3-6%, Propylene glycol laurate 1-3%, Fragrance 0.5-2%, Menthol 0.1-0.4%, Anhydrous ethanol 8-11%, Phenoxyethanol 0.3-0.7%, Polyquaternium-11 0.3-0.6%, Propylene glycol balance.

[0016] Hair mask is a hair care product that nourishes hair. The nutrients and moisture contained in it will penetrate deeply into the hair through the hair scales, help repair damaged tissues, improve hair quality, and make the hair instantly smooth. Traditional hair masks are generally thick and paste-like in texture. The method of use is to squeeze out excess water on the hair, take an appropriate amount of hair mask on the palm, gently and evenly apply it on the hair with both hands, let it stand for 10 minutes, and finally rinse with warm water. The present invention can produce a liquid hair mask with a transparent appearance, which is different from the traditional paste texture. It will also generate heat when used, achieving the effect of hair treatment.

[0017] The present invention also provides a skin care preparation, comprising component A and component B, wherein the component A comprises the alcohol agent as described above and a common matrix of an external skin care formulation, the alcohol agent comprises 5-35 parts of a fatty alcohol, 0.5-10 parts of a surfactant, 40-94 parts of a polyol and 0.5-15 parts of oil, and the common matrix of the external skin care formulation comprises 0.5-1.5 parts of 4-tert-butyl cyclohexanol and 1-3 parts of anhydrous ethanol; the component B is water; and the mass ratio of the component A to the component B is 1:1.

[0018] In some embodiments, the skin care preparation comprises component A and component B, wherein component A comprises the following components in percentage by mass: 25-35% myristyl alcohol, 2-4% polyglycerol-10 oleate, 2-5% propylene glycol laurate, 0.5-1.5% 4-tert-butyl cyclohexanol, 1-3% anhydrous ethanol, and the remainder propylene glycol; component B is water; and the mass ratio of component A to component B is 1:1.

[0019] The skin care preparation of the present invention can apply 4-tert-butyl cyclohexanol in non-cream and non-oil formulations, thereby expanding its application scenarios. It should be noted that in actual applications, the skin care preparation of the present invention can be only component A, which can be used alone when used, or mixed with water when used to form a cream.

[0020] Compared with the prior art, the alcohol agent that forms frosting when in contact with water and its application in cosmetics of the present invention have the following beneficial effects: The invention adopts the concept that fatty alcohol precipitates when it meets water and is re-emulsified into cream by surfactant to produce a liquid alcohol agent with transparent appearance. The liquid alcohol agent turns into cream when it meets water, and the operation is simple, which can be realized during the use of the product. Moreover, the liquid alcohol agent can generate heat by itself, and is warm and moisturizing when it is just used. After meeting water, it can be turned into cream by gently circling with fingers, and can be used in skin care products and hair care products.

[0021] By dissolving active ingredients such as ester-soluble and alcohol-soluble active ingredients in the liquid alcohol agent of the present invention, and then adding water agent to apply it into a cream before use, the active ingredients are prevented from being emulsified in the cream in advance, which may cause discoloration and loss of activity. In addition, since the state is an essence during storage and a cream during use, the problem of greasy skin feeling and acne is solved at the same time, and the application scenarios of such active ingredients are expanded.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below in conjunction with specific embodiments.

[0024] Embodiment A, B, C, D The effects of different amounts of fatty alcohol added on the frosting technology of the alcohol agent of the present invention when it meets water are investigated by designing the amount of fatty alcohol with a certain gradient concentration. The formula is shown in Table 1 below: Table 1

[0025] The samples of Examples A, B, C, and D all appear as transparent liquids. Figure 1 , and all embodiments will frost when exposed to water, see Figure 2 .Depend on Figure 1 and Figure 2 It can be seen that in the present invention, the addition amount of fatty alcohol (myristyl alcohol) is 5-35% to form a transparent liquid, which turns into frost when it comes into contact with water.

[0026] Comparative Example E, Examples F, G, H The effects of different amounts of surfactant added on the frosting technology of the alcohol agent in the present invention when it meets water are investigated by designing the amount of surfactant used in a certain gradient concentration. The formula is shown in Table 2 below: Table 2

[0027] Comparative Example E has a transparent liquid appearance, and precipitates after contacting water. Examples F, G, and H all have a transparent liquid appearance, and emulsify into a cream when contacting water. Figure 3 and Figure 4 .Depend on Figure 3 and Figure 4 It can be seen that without adding surfactant (polyglycerol-10 oleate), it is difficult to emulsify into frost when it comes into contact with water. When the surfactant (polyglycerol-10 oleate) is added in an amount of 0.5-10%, a transparent liquid can be formed, and it can frost when it comes into contact with water.

[0028] Examples I, J, K, L By designing and comparing different surfactants, the effects of different surfactants on the frosting technology of the alcohol agent of the present invention when it meets water are investigated. The formula is shown in Table 3 below: Table 3

[0029] The above-mentioned Examples I, J, K, and L are tests using the same amount of different surfactants, respectively. The surfactant used in Example I is polyglyceryl-10 oleate; the surfactant used in Example J is polyglyceryl-2 laurate; the surfactant used in Example K is polyglyceryl-10 laurate; and the surfactant used in Example L is glyceryl stearate / PEG-100 stearate.

[0030] The samples of Examples I, J, K, and L all have the appearance of transparent liquids and turn into frost when exposed to water. Figure 5 and Figure 6 .Depend on Figure 5 and Figure 6 It can be seen that the different surfactants used in the above embodiments I, J, K, and L can all be emulsified into frost when exposed to water.

[0031] Embodiments M, N, O, P, Q, R The effects of different amounts of added oil on the frosting technology of the alcohol agent of the present invention when it meets water are investigated by designing the amount of oil with a certain gradient concentration. The formula is shown in Table 4 below: Table 4

[0032] The samples of Examples M, N, O, P, Q, and R all have a transparent liquid appearance and turn into frost when exposed to water. Figure 7 and Figure 8 .Depend on Figure 7 and Figure 8It can be seen that the oil (propylene glycol laurate) with different contents in the above embodiments M, N, O, P, Q, and R can all be emulsified into cream when exposed to water.

[0033] Embodiment S, T, U, V Different oils were designed to investigate the effects of different oils on the frosting technology of the alcohol agent of the present invention when it meets water. The formula is shown in Table 5 below: Table 5

[0034] The above-mentioned Examples S, T, U, and V are tests using the same amount of different oils, wherein the oil in Example S is propylene glycol laurate, the oil in Example T is ethylhexyl palmitate, the oil in Example U is 26% white oil, and the oil in Example V is DC345.

[0035] The test results show that the samples of Examples S, T, U, and V all have a transparent liquid appearance and turn into frost when exposed to water. Fig. 9 and Fig.10 The experimental results show that different types of oils and fats in the above embodiments S, T, U, and V can be emulsified into frost when exposed to water.

[0036] Embodiment W, X, Y By designing different polyols, the influence of different polyols on the frosting technology of the alcohol agent of the present invention when it meets water is investigated. The formula is shown in Table 6 below: Table 6

[0037] The above-mentioned Examples W, X, and Y are tests using the same amount of different polyols, wherein the polyol used in Example W is propylene glycol, the polyol used in Example X is butylene glycol, and the polyol used in Example Y is ethanol.

[0038] The test results show that the samples of Examples W, X, and Y all have a transparent liquid appearance and turn into frost when exposed to water. Fig.11 , 12 The experimental results show that the different types of polyols in the above examples W, X, and Y can all be emulsified into frost when exposed to water.

[0039] Test Example 1-3 A liquid hair mask, comprising the raw materials shown in Table 7 below: Table 7

[0040] The preparation process of the above-mentioned test examples 1-3 is as follows: after heating phase A to 80 degrees to dissolve, phase A1 is added in sequence and stirred for 3-5 minutes, and then the mixture is cooled to 50 degrees and the premixed phases B and B1 are added and stirred evenly.

[0041] Test Example 1-3 is a liquid hair mask preparation, which is a transparent liquid in appearance and turns into cream when it comes into contact with water. The method of use is as follows: directly apply the liquid hair mask to the hair that has just been rinsed. When the liquid hair mask comes into contact with the wet water on the hair, it turns into cream, which will then generate heat by itself, producing an effect similar to hair treatment.

[0042] After mixing the liquid hair mask of Test Example 1 with pure water in a mass ratio of 1:1, the mixture was placed under a microscope for observation, and droplets in the dispersion were visible. Fig.14 . It shows that when the liquid hair mask is mixed with pure water in a ratio of 1:1, a cream is formed.

[0043] Take natural hair bundles as the test object, use the sample to be tested for care and wash it clean, measure the width of the hair bundle after washing and drying, and measure two positions on the same hair bundle. The larger the measured hair bundle width value, the better the hair bundle fluffiness effect. Among them, the blank group (tap water), the matrix group (hair mask without HCPOLYMER 1S(M)), and the experimental group (liquid hair mask in test example 1). The test results are shown in Fig.15 , Figure 24-Figure 29 .Depend on Fig.15 , Figure 24-Figure 29 It can be seen that compared with the blank group and the matrix group, the hair bundle width of the experimental group after use is wider, indicating that the liquid hair mask of the present invention has a good fluffy effect.

[0044] Use the liquid hair mask of Test Example 1 according to the instructions, blow dry your hair after use, and test the hair fluffy and smooth effect. Fig.16 .Depend on Fig.16 It can be seen that the hair was dry and frizzy before shampooing, but after using the liquid hair mask of Test Example 1, the hair became fluffy and smooth. This shows that the alcohol agent of the present invention can greatly improve the fluffy and smooth effect of hair in hair care products, and is easy to use.

[0045] Test Example 4-6 A skin care preparation comprises component A and component B, wherein component A is composed of the raw materials shown in Table 8 below: Table 8

[0046] The preparation process of the component A of the above-mentioned test example 4-6 is as follows: after heating the phase A to 80 degrees to dissolve, add the premixed phase B and stir evenly.

[0047] The components A of test examples 4-6 all have the appearance of transparent liquids and turn into frost when in contact with water.

[0048] After mixing the component A of Test Example 4 with the pure water of component B at a mass ratio of 1:1, the mixture was placed under a microscope for observation, and droplets in the dispersion could be seen. Fig.18It shows that after the A component and pure water are mixed in a ratio of 1:1, a cream is formed. After testing at 45℃ for half a month, there is no color change.

[0049] Nicotinic acid ester irritates the skin, producing erythema and dividing into two areas. Fig.19 Then one of the areas was treated with the skin care preparation of Test Example 4, and the other area was not treated as a blank group. After 15 minutes, the redness reduction effect of the two areas was observed. Fig. 20 .from Fig. 20 It can be seen that the skin care preparation of Test Example 4 has a more significant redness-removing effect after treatment, and the redness is removed faster than that of the untreated group in the same period of time. This shows that the skin care preparation of the present invention has a redness-removing and soothing effect, and the preparation successfully applies 4-tert-butyl cyclohexanol to non-cream and non-oil formulations, expanding its application scenarios.

[0050] Test Examples 7-9 A skin care preparation containing 4-hexylresorcinol comprises a component A and a component B, wherein the component A is composed of the raw materials shown in Table 9 below: Table 9

[0051] The preparation process of the component A of the above-mentioned test example 7-9 is as follows: after heating the phase A to 80 degrees to dissolve, add the premixed phase B and stir evenly.

[0052] The appearance of component A in test examples 7-9 is a transparent liquid, and it forms frost when it comes into contact with water. Component A and component B pure water are mixed in a mass ratio of 1:1 to form a cream.

[0053] Most creams on the market that contain 0.5% 4-hexylresorcinol will oxidize and lose their activity if stored at high temperature (45°C) for 3 months, which is manifested by the product turning yellow. Fig. 22 The formula of the cream containing 0.5% 4-hexylresorcinol on the market is shown in Table 10 below: Table 10

[0054] When component A of test example 7 was stored at high temperature (45°C) for 3 months, it still maintained a colorless and transparent appearance or only slightly yellowed, which significantly slowed down the yellowing speed and reduced the degree of oxidative deactivation. Fig.23 It is shown that the skin care preparation of the present invention successfully applies 4-hexylresorcinol to non-cream and non-oil formulations, thereby expanding its application scenarios, protecting its activity, and slowing down its yellowing rate.

[0055] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
