Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and specifically relates to a color developing composition and a method for using and application thereof, and in particular to a preparation of a layered structure (vesicle or liquid crystal) with a color developing effect prepared by using a surfactant and its application. Background Art

[0002] At present, there are a wide variety of cosmetics on the market. Each product highlights its appeal in its own unique way to stimulate consumers' desire to buy. In order to increase product sales, brands focus on the design of color and texture in containers and packaging. In terms of contents, most of them are currently working on the makeup formula, enhancing the appearance of the formula through a combination of three-dimensional molding and high-brightness pearlescent agents, and conveying the message to consumers that "you will become beautiful after using it." However, in the field of skin care, there is a relative lack of cases in the study of the appearance of preparations. Basically, mica, cholesteric liquid crystals, and high-carbon alcohol crystals are used to make pearlescent materials or pigments (natural or synthetic) to attract consumers. However, these solutions also have some flaws: mica has bright pearl luster but high density. Mica tends to sink to the bottom when stored for a long time, making it unsuitable for aqueous solutions, emulsions and essences, and the color development mechanism is mainly light reflection; the pearlescent color development mechanism formed by cholesteric liquid crystals and high-carbon alcohol crystals is mainly light reflection, but due to changes in temperature conditions and long-term storage, the liquid crystal and crystal state will change, the color will disappear or there will be problems with the stability of the formula, and the pearlescent color is only white or silver, and the color is not rich; the color development mechanism of pigments is the complementary color of natural visible light, but pigments (natural) are sensitive to ultraviolet rays, have poor heat stability, and are prone to color attenuation or discoloration; pigments (synthetic) do not conform to current environmental protection and green trends. Summary of the invention

[0039] In a third aspect, the present invention provides a use of the aforementioned color-developing composition in the preparation of color-developing cosmetics, mouthwashes, or food and beverages.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] 1) The present invention develops an optical principle produced by a layered structure (lamellar liquid crystal or vesicle) produced solely by the compounding of surfactants, so that the formulated color-developing composition has a color appearance including colorful aurora colors (aurora color definition: a single color or a combination of multiple colors); the color seen by the front reflected light and the color seen by the back transmitted light are two different colors of light in a complementary color relationship; when the observation angle deviates from the incident light angle, it can be seen that the color will also change and different colors will be observed; some preparations have fire color or rainbow luster under a polarizing plate, and the color stability is excellent over time, thereby providing the expected effects that these traditional appearances cannot achieve, and have excellent moisturizing effects.

[0042] 2) The present invention can further improve the color development effect and color development stability by further optimizing the type selection of each component in the color development composition, the overall HLB value range of the non-ionic surfactant used, and the mass ratio of the non-ionic surfactant used to the ionic surfactant used.

[0061] In a specific embodiment of the present invention, the specific method for performing performance testing is as follows:

[0062] 1) Evaluation of color development effect and color development stability

[0063] The instant color development of each color developing composition was visually evaluated in a dark room or under indoor light according to the following criteria. The color developing composition was also observed for stability under specific conditions (color development stability criteria), then returned to room temperature and subjected to the same visual evaluation to evaluate the color development stability.

[0064] - Instant color rendering criteria -

[0065] Acceptable (Excellent) ◎: No turbidity is observed at all, the color is good, and there is an aurora color.

[0066] Acceptable (good) ○: Some turbidity is observed, but the color development is good; or, no turbidity is observed at all, but the color development is weak.

[0067] Unqualified (slightly poor) △: Some white turbidity and weak color development.

[0068] Unqualified (very poor) ×: Severe turbidity, almost no color development; or some turbidity, no color development.

[0069] - Criteria for determining color stability -

[0070] Pass (Excellent)◎: Cycle test (-10~40℃: stored at -10℃ for 24h; stored at 25℃ for 24h; stored at 40℃ for 24h; stored at 25℃ for 24h and 4 days as a cycle), no obvious change in color for 1 month.

[0071] Acceptable (good) ○: No significant change in color after 24 hours at room temperature.

[0072] Unqualified ×: The color disappears or is significantly weakened within 24 hours at room temperature.

[0073] 2) Criteria for determining the formation of layered structures

[0074] Observe whether there is a layered liquid crystal texture through the polarizing plate

[0075] ○: There is polarization phenomenon

[0076] ×: No polarization

[0077] 3) Measurement of skin moisture content and evaluation of moisture retention function

[0078] The moisture content of the stratum corneum of the skin was tested using the Corneometer CM825 (Courage-Khazaka) instrument for 4 hours. The test method was QB / T 4256-2011. The percentage increase in the moisture content of the stratum corneum of the skin was calculated. The higher the value, the higher the moisture retention capacity.

[0079] Moisturizing efficacy criteria

[0080] ○: After 4 hours, the increase rate of moisture content in the stratum corneum of the skin is ≥10%

[0081] ×: After 4 hours, the increase rate of moisture content in the stratum corneum of the skin is <10%

[0082] In the preliminary research of the present invention, according to the reports in the existing literature, the critical packing parameter (CPP) has a close relationship with the aggregates. When CPP < 1 / 3, it is a spherical micelle; when 1 / 3 < CPP < 1 / 2, it is a rod-shaped micelle; when 1 / 2 < CPP < 1, it is a vesicle; when CPP ≈ 1, it is a flat sheet; and when CPP > 1, an inverse micelle is formed. Therefore, vesicles can be formed by using amphiphiles with 1 / 2 < CPP < 1 or mixing an appropriate amount of various amphiphiles to form an amphiphile mixture system with 1 / 2 < CPP < 1. So, the present invention selects a combination of surfactants with an overall HLB value in the range of 5 - 10 to attempt to develop a color-developing preparation.

[0083] The state of surfactants dissolved in water generally varies with changes in temperature and concentration, accompanied by various changes in the aggregate morphology, such as single-molecule dispersions, micellar solutions, or liquid crystal formation. Many existing surfactants do not show spherical micelles at low concentrations and can be classified as water-insoluble surfactants. The dissolution behavior of water-insoluble surfactants is different from that of ordinary surfactants, and its uniqueness lies in that it is easy to form liquid crystals even at low concentrations. Many so-called double-chain ionic surfactants in the dissolved state, such as lecithin and dialkyldimethylammonium chloride, have been reported to exhibit this unique dissolved state. Based on this theory, the present invention focuses on water-insoluble surfactants with an overall HLB value in the range of 5 - 10, among which surfactants with a single highly linear alkyl group and a hydrophilic structure of hydroxyl have this property.

[0084] Based on this, in the preliminary experiments of the present invention, surfactants were screened. A single non-ionic surfactant with an HLB value in the range of 5 - 10 was added to water to observe color development. The formulations (mass percentages) of each experimental group are shown in Table 1 below, and the color development results are shown in Table 1 and Figure 1 as shown. From the results in Table 1 and Figure 1 it can be seen that the immediate color development evaluations of experimental groups 1-1, 1-2, 1-3, and 1-4 are all unqualified (very poor). Therefore, a single non-ionic surfactant cannot develop color.

[0085] Table 1

[0086]

[0087] The present invention further compounded two non-ionic surfactants and controlled the overall HLB value to be in the range of 7.0 - 8.0, and then added them to water to observe color development. The formulations (mass percentages) of each experimental group are shown in Table 2 below, and the color development results are shown in Table 2 and Figure 2 ( Figure 2 in which, the upper figure is the front view and the lower figure is the vertical view) as shown. From Table 2 and Figure 2The results show that the instant color development evaluation of experimental groups 1-5, 1-6, 1-7, 1-8, and 1-9 is unqualified (very poor), so when non-ionic surfactants are compounded in pairs and the overall HLB value is controlled under the conditions that meet the formation of vesicles, color development is still not possible.

[0088] Table 2

[0089]

[0090]

[0091] The present invention further adds a single nonionic surfactant and a single anionic surfactant to water for color development. The formula (mass percentage) of each experimental group is shown in Table 3 below. The color development results are shown in Table 3 and Figure 3 As shown in Table 3 and Figure 3 The results show that the instant color development evaluation of experimental groups 1-10 and 1-11 is unqualified (very poor), so the use of a single nonionic surfactant and a single anionic surfactant in combination also fails to develop color.

[0092] Table 3

[0093]

[0094] Based on the above experimental studies, the present invention further optimizes the selection of surfactants, thereby obtaining the color developing composition of the present invention. The following examples will describe the color developing composition of the present invention in detail.

[0095] Examples 1-5

[0096] Embodiments 1-5 provide a color development composition, which includes a nonionic surfactant (a) polyglycerol-2 laurate and b) propylene glycol laurate), and also includes c) an anionic surfactant or a cationic surfactant. The specific raw materials used in the color development composition of Embodiments 1-5 are shown in Table 4. Each color development composition prepared in Embodiments 1-5 is added to water according to the mass percentage shown in Table 4, and the color development is observed. The specific method is:

[0097] S1: Weigh the raw materials of the color developing composition and water according to the ratio shown in Table 4;

[0098] S2: Put all the ingredients into the main pot, heat to above 75°C while stirring, and continue stirring for 10 minutes at a stirring speed of 450 rpm;

[0099] S3: Cool in a water bath to below 35°C, stirring at 450 rpm throughout the process.

[0100] The solution after the color-developing composition was mixed with water was evaluated. The results of the immediate color development evaluation, color development stability evaluation, and layer structure formation state evaluation are shown in Table 4 and Figure 4 ( Figure 4 , the upper figure is a front view and the lower figure is a vertical view).

[0101] Comparative Example 1-2

[0102] Comparative Example 1-2 provides a color development composition, which includes a nonionic surfactant (a) polyglycerol-2 laurate and b) propylene glycol laurate), and also includes c) a zwitterionic surfactant. The specific raw materials used in the color development composition of Comparative Example 1-2 are shown in Table 4. Each color development composition prepared in Comparative Example 1-2 is added to water according to the mass percentage shown in Table 4, and the color development is observed in the same manner as in Example 1-5.

[0103] The solution after the color-developing composition was mixed with water was evaluated. The results of the immediate color development evaluation, color development stability evaluation, and layer structure formation state evaluation are shown in Table 4 and Figure 4 ( Figure 4 , the upper figure is a front view and the lower figure is a vertical view).

[0104] Table 4

[0105]

[0106] From Table 4 and Figure 4 It can be seen from the results that the ionic surfactants used in Implementation Columns 1-4 are anionic surfactants, and the instant color development evaluation is qualified (excellent), and the layered structure formation state evaluation has polarization phenomenon. Among them, Examples 1 and 4 use a monoalkyl chain anionic surfactant, and its color development stability evaluation is qualified (good), while Examples 2 and 3 use Gemini anionic surfactants, and its color development stability evaluation is qualified (excellent). The ionic surfactant used in Implementation Column 5 is a cationic surfactant, and the result is that the instant color development evaluation is qualified (excellent), the color development stability evaluation is qualified (good), and the layered structure formation state evaluation has polarization phenomenon. The ionic surfactant used in Comparative Columns 1-2 is an amphoteric surfactant, and its instant color development evaluation is unqualified (very poor), and the layered structure formation state evaluation has no polarization phenomenon.

[0107] The results of Example 1-5 and Comparative Column 1-2 show that both anionic surfactants and cationic surfactants in ionic surfactants are helpful for color development, and Gemini anionic surfactants are more helpful for color development stability. The reason may be that single-chain anionic surfactants such as sodium methyl cocoyl taurate and fatty acid salts will separate from the layered structure due to their own structural reasons and form spherical micelles by themselves, while Gemini ionic surfactants are not easy to separate from the layered structure.

[0108] Embodiment 6-11

[0109] Embodiment 6-11 provides a color development composition, which includes a nonionic surfactant (a) polyglycerol-2 laurate and b) propylene glycol laurate), and also includes c) an anionic surfactant. The specific raw materials used in the color development composition of Embodiment 6-11 are shown in Table 5. Each color development composition prepared in Embodiment 6-11 is added to water according to the mass percentage shown in Table 5, and the color development is observed in the same manner as in Embodiment 1-5.

[0110] The solution after the color-developing composition was mixed with water was evaluated. The results of the immediate color development evaluation, color development stability evaluation, and layer structure formation state evaluation are shown in Table 5 and Figure 5 ( Figure 5 , the upper figure is a front view and the lower figure is a vertical view).

[0111] Comparative Examples 3-4

[0112] Comparative Examples 3-4 provide a color development composition, which includes a nonionic surfactant (a) polyglycerol-2 laurate and b) propylene glycol laurate), and also includes c) an anionic surfactant. The specific raw materials used in the color development composition of Comparative Examples 3-4 are shown in Table 5. Each color development composition prepared in Comparative Examples 3-4 is added to water according to the mass percentage shown in Table 5, and the color development is observed in the same manner as in Examples 1-5.

[0113] The solution after the color-developing composition was mixed with water was evaluated. The results of the immediate color development evaluation, color development stability evaluation, and layer structure formation state evaluation are shown in Table 5 and Figure 5 ( Figure 5 , the upper figure is a front view and the lower figure is a vertical view).

[0114] Table 5

[0115]

[0116]

[0117] From Table 5 and Figure 5The results show that the overall HLB value of the nonionic surfactants used in Examples 6-11 is between 7.00 and 8.5, and the mass ratio of nonionic surfactants to ionic surfactants is between 147 and 586.

In the concentrated color-developing composition, the overall HLB value of component a) and component b) is 7.247.44, and the total weight of component a) and component b) is 729 times the weight of component c).

[0166] The preparation method of the concentrated color developing composition is as follows:

This shows that the surfactant used in the present invention forms a layered structure in a low-concentration aqueous solution, and the arrangement of the bimolecular membrane is within a specific range, which can show a variety of different colors of visible light.
