Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a composite suspension thickening composition and application thereof. Background Art

[0002] Emulsion skin care products on the market often use emulsifiers to form a monolayer on the interface between water and oil phases, reduce their interfacial tension, and mix to form a uniform dispersion. Emulsifiers are unstable and skin-friendly, and can easily penetrate the skin. Excessive use may cause skin irritation, dryness, sensitivity, inflammation, etc. At the same time, due to the presence of emulsifiers, the spreading resistance of the emulsion is increased, and the texture appears to be thick and sticky. Therefore, in order to reduce the burden on the skin, more and more cosmetics are reducing the use of emulsifiers and adding functional ingredients to achieve scientific simplification of ingredients while ensuring multiple functions, so as to meet the requirements of precise care.

[0003] CN116889527A discloses a mild and oil-free facial mask and a preparation method and application thereof. The mild and oil-free facial mask is obtained by immersing a facial mask matrix in a facial mask liquid. The raw materials for preparing the facial mask liquid include, by weight, 1-10 parts of an emollient, 0.1-5 parts of fermented oil, 5-15 parts of a humectant, 0.01-1 parts of a thickener, 0.01-1 parts of a pH regulator, 0.1-2 parts of an antioxidant, and 80-95 parts of water. The mild and oil-free facial mask prepared by the invention does not require the addition of an emulsifier, is less irritating than a traditional emulsified oil-applied facial mask, and also has excellent moisturizing properties, and is suitable for people with skin allergies.

[0004] CN110101627A discloses an essence with suspended micro beads and a preparation method thereof, belonging to the technical field of skin care products and their preparation. An essence with suspended micro beads and a preparation method thereof, the essence has a novel micro bead suspension appearance, good skin adhesion when used, oily and silky without being greasy, and the skin is moisturized and soft after absorption. In the absence of an emulsifier, the protective effect of the emollient is achieved, and the loss of skin moisture is effectively reduced. Polyacrylic acid polymers are used to evenly suspend oil-soluble ingredients such as emollient oils and oil-soluble active substances in the form of spherical micro beads, and the size, softness and hardness of the micro beads are moderate. The product is safe, mild and has good stability. Water-soluble active substances such as moisturizing and anti-aging are absorbed by the skin with polyols such as glycerol as carriers; at the same time, the oil-soluble active ingredient shark liver alcohol that slows down photoaging damage uses squalane and other oils as carriers to protect the skin; the product achieves a dual approach of slowing down natural aging and photoaging to comprehensively repair and tighten the skin.

[0005] However, most of the active ingredients in the prior art are ionic, and their addition may make the system thinner or unstable, limiting the amount added in the formula and the efficacy of the product. If the amount of thickener is increased at the same time, it may cause the product to feel sticky, slow to absorb, and have a heavy residual feeling. Therefore, it is necessary to optimize a suspension thickening composition that is suitable for streamlining the skin care system while stabilizing oils and active ingredients and providing a refreshing skin feeling after use. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide a composite suspension thickening composition and its application. The composition can solve the problem of poor viscosity of a single thickening system after adding multiple active ingredients. A small amount of the composition can stabilize oils and functional active ingredients and keep the system stable. The cosmetic product prepared by using this combination has the advantages of simple formula, light skin feel, non-greasy and easy absorption.

[0095] Comparative Application Example 1-2

[0096] The comparative application example provides two kinds of essence milks, which differ from application example 1 only in that the composite suspension thickening composition of embodiment 1 is replaced by the composite suspension thickening composition of comparative example 1-2 in equal amounts, and the remaining components and amounts are consistent with those of application example 1, and the preparation method refers to application example 1.

[0097] Comparative Application Example 3

The remaining components and amounts are consistent with those of Application Example 1, and the preparation method refers to Application Example 1.

[0099] Test Example 1

[0100] The viscosity of the essence milk of application examples 1-9 and comparative application examples 1-3 was tested, and then the active ingredient (0.6% of the total amount of the essence milk) was added to the essence milk of application examples 1-9 and comparative application examples 1-3 and mixed and homogenized (the active ingredient added in application example 1 was a mixture of dipotassium glycyrrhizinate, carnosine and panthenol in a mass ratio of 1:1:1, the active ingredient added in application example 2 was dipotassium glycyrrhizinate and panthenol in a mass ratio of 1:1, the active ingredient added in application example 3 was panthenol, and the active ingredients added in the other application examples were consistent with those in application example 1), and the viscosity was continued to be measured, and centrifugation was performed to test whether it was layered. The results are shown in Table 1.

[0101] Table 1

[0102]

[0103] Note: In application example 5, since the viscosity has exceeded the range of 2#3r, the 3#12r rotor is replaced for testing.

[0104] In comparative application example 3, since the viscosity is too low, the rotation speed is adjusted to 60r.

[0105] As shown in Table 1, compared with Comparative Application Example 3, the viscosity of the essence milk provided by Application Examples 1-3 of the present invention with the composite suspension thickening composition added thereto remains basically stable before and after the addition of one or more active ingredients, and the centrifugal test is qualified.

[0106] It can be seen from Application Example 4 that when xanthan gum is not added to the composition, the viscosity of the system changes more significantly after the active ingredient is added;

[0107] It can be seen from Application Examples 5-6 that the ratio of the components in the composition also affects the viscosity of the system;

[0108] It can be seen from Application Examples 7-9 that the choice of oil has an impact on the centrifugal test of the system, and squalane, isononyl isononanoate and polydimethylsiloxane synergistically enhance the centrifugal stability of the system after the active ingredients are added;

[0109] By comparison with Application Examples 1-2, it can be seen that when the composition lacks any one of polyacrylate cross-linked polymer-6 and Sphingomonas fermentation product extract, the viscosity of the system changes significantly after the active ingredient is added.

[0110] Test Example 2

[0111] The stability test includes high temperature, low temperature and hot and cold cycle test. The samples provided in Application Examples 1-9 and Comparative Application Examples 1-3 with active ingredients added in the test examples were placed at 45°C, 25°C, -12°C, and -12 to 45°C for 1 month, and the appearance of the product was observed at 0 weeks and 1 month for abnormal phenomena such as turbidity and stratification, and the viscosity value was measured. The test results are shown in Table 2-5.

[0112] Table 2

[0113]

[0114]

[0115] Table 3

[0116]

[0117] Table 4

[0118]

[0119]

[0120] Table 5

[0121]

[0122] Note: In application example 5, since the viscosity has exceeded the range of 2#3r, the 3#12r rotor is replaced for testing.

[0123] In comparative application example 3, since the viscosity is too low, the rotation speed is adjusted to 60r.

[0124] It can be seen from the data in Tables 2-5 that, compared with Comparative Application Example 3, the essence milk provided in Application Examples 1-3 of the present invention has little change in appearance and viscosity after being placed in a high and low temperature environment for one month after adding active ingredients, and has excellent high and low temperature stability.

[0125] It can be seen from Application Example 4 that when xanthan gum is added to the composition, the stability of the system can be improved;

[0126] It can be seen from Application Examples 5-6 that when the polyacrylate cross-linked polymer-6, the extract of the fermentation product of Sphingomonas and the xanthan gum are within the defined range of the present invention, the stability of the system can be better;

[0127] From Application Examples 7-9, it can be seen that the choice of oil also affects the stability viscosity of the system, and squalane, isononyl isononanoate and polydimethylsiloxane work synergistically to make the stability of the system more excellent;

[0128] As can be seen from the comparison of Application Examples 1-2, when the composition lacks any one of polyacrylate cross-linked polymer-6 and Sphingomonas fermentation product extract, the stability of the system is poor.

[0129] Test Example 3 Human skin closed patch test

[0130] The specific method is as follows: 30 females aged 18-35 years old with no history of allergies were selected, and each subject tried the product prepared in Application Examples 1-9. After cleaning the subject's arm, the patch tester with the sample was applied to the selected position on the curved side of the arm with a non-irritating tape. After pasting, press it lightly with your fingers to make it evenly attached to the skin for 24 hours. The subject kept the patch area dry within 24 hours, avoiding intense exercise, scratching the patch area, and long-term sunlight exposure. After 24 hours, the test object was removed and marked, and after 30 minutes, the indentation disappeared and the judgment was made under sufficient light.

[0131] The grading standards for adverse skin reactions are shown in Table 6:

[0132] Table 6

[0133]

[0134] The results are shown in Table 7:

[0135] Table 7

[0136]

[0137]

[0138] It can be seen from the data in Table 7 that among the 30 subjects, no adverse skin reactions were observed 30 minutes, 24 hours, and 48 hours after the spot tester was removed, indicating that the product of the present invention is safe and non-irritating.

[0139] Test Example 4 Consumer Questionnaire Survey

[0140] 30 males / females aged 18 to 55 years old who met the inclusion criteria for the volunteers were selected. The subjects were randomly selected to use the sample of Application Example 1 on one half of their face and the sample of Comparative Application Example 3 on the other half of their face. After the subjects used the test samples on their faces, the results of the questionnaire survey on various satisfaction items were immediately counted and analyzed.

[0141] The results show that:

[0142] 90% of the subjects believed that the sample of Application Example 1 was not sticky (refreshing) when applied by fingers compared with the sample of Comparative Application Example 3;

[0143] 86.675% believed that the film remaining on the skin after 2 minutes of absorption of the sample of Application Example 1 was thinner than that of the sample of Comparative Application Example 3;

[0144] 90% of the subjects believed that the sample of Application Example 1 was easier to absorb during application than the sample of Comparative Application Example 3;

[0145] 93.33% of the subjects believed that the sample of Application Example 1 was less sticky on the skin / fingers (ie, more refreshing) 2 minutes after absorption compared with the sample of Comparative Application Example 3.

[0146] It can be seen that, compared with the product without adding the composition of the present invention, the essence milk of the present invention can have a good use effect by adding the composite suspension thickening composition, and consumers have a higher evaluation after use.
