Description

Technical Field

[0001] This application relates to the field of cosmetic technology, and more specifically, to a loose powder containing Bifida ferment filtrate and a method for preparing the same. Background Technology

[0002] Loose powder is a type of facial cosmetic, also known as "setting powder" or "setting powder." Its main function is to set makeup. It has a fine texture, low density, and high light transmittance. It can prevent oily skin from becoming overly smooth or sticky, reduce sweat and sebum, enhance the longevity of cosmetics, smooth pores, brighten color, and give the skin a soft, velvety feel.

[0003] Currently, most setting powders on the market use talc, silica, and boron nitride as the main powder fillers. To increase the transparent and lightweight makeup effect, the overall particle diameter of these powder fillers is controlled between 10-100μm when selecting these raw materials. In addition, to prevent clumping, setting powders do not add too much oil as a binder. Therefore, the problem of powder fallout often occurs. Moreover, although the powder fillers such as talc, zinc oxide, and titanium dioxide have strong coverage and absorption, excessive use can easily absorb moisture from the skin, leading to dry skin and resulting in caking, dryness, and makeup fading.

[0004] In the prior art, Chinese invention patent application document with application number CN2021104904645 discloses a moisturizing setting powder, comprising the following components: phase A 90-95%, phase B 2-6%, phase C 1-2%, phase D 0.1-0.2%, and balance water, wherein phase A consists of: synthetic fluorophlogopite 50%, mica 20%, silica 20%, titanium dioxide 0.55%, starch octenyl succinate aluminum 1%, and tin oxide 1%; phase B consists of: cetyl ethylhexanoate 2% and polydimethylsiloxane 3.8%; phase C consists of: ethylhexylglycerin 1% and 1,2-hexanediol 0.5%; and phase D consists of: gellan gum 0.15%, with a particle size of 1.5-2μm.

[0005] Regarding the aforementioned technologies, a small amount of phase B is added as an oil-phase binder, and gellan gum is used as a water-phase raw material. This results in good setting and moisturizing effects for the setting powder, a better skin feel, and less tendency for powder fallout. However, once the hydrophilic raw materials such as gellan gum are completely absorbed by the skin or evaporate externally, they lose their moisturizing effect, and the skin is prone to dryness and powder caking. Summary of the Invention

[0006] In order to prolong the moisturizing time of loose powder and improve its long-lasting moisturizing effect, this application provides a loose powder containing Bifida ferment filtrate and a method for preparing the same.

[0007] In a first aspect, this application provides a powder containing Bifida ferment filtrate, employing the following technical solution:

[0008] A powder containing Bifida ferment filtrate, comprising phases A, B, C and D;

[0009] Based on the weight percentage of the powder, phase A comprises the following raw materials by mass percentage: 3-44 parts filler;

[0010] Based on the weight percentage of the loose powder, phase B comprises the following raw materials by weight percentage: 1-50 parts of Bifida ferment lysate, 0.1-0.5 parts of preservative, and 0.1-0.5 parts of cooling agent;

[0011] Based on the weight percentage of the loose powder, the C phase comprises the following raw materials in the following mass percentages: 1-10 parts of 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine pretreated silica;

[0012] Based on the weight percentage of the loose powder, phase D comprises the following raw materials by weight percentage: 0.5-1.5 parts of preservative and 0.1-0.5 parts of humectant.

[0013] By employing the above technical solution, Bifida ferment lysate is added to phase B, and silica is pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine to encapsulate it, thereby allowing the slow release of the Bifida ferment lysate. The main component of the silica pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine is silicon dioxide, which is hydrophilic. After pretreatment with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine, the silica becomes hydrophobic, thus increasing its oil-controlling ability and achieving a long-lasting oil-controlling effect. The Bifida ferment lysate contains abundant vitamins, minerals, amino acids, and biopolysaccharide complexes essential for the human body. Biotechnology-derived active substances specifically support skin protection and gene repair, providing preventative care for normal skin and gene repair solutions for problem skin. As a moisturizer and antioxidant, it visibly reduces fine lines and wrinkles, whitens and fades blemishes, significantly improves skin radiance and evenness of skin tone, promotes the skin's natural DNA repair mechanism after UV exposure, prevents collagen breakage, and promotes youthful, healthy, safe, and resilient genes from the source. The slowly released bifida ferment lysate continuously nourishes the skin, keeping it supple, radiant, soft, and delicate. The cooling agent allows the loose powder to slowly release a cooling sensation after application, providing a refreshing feeling while moisturizing.

[0014] Optionally, the filler may comprise, by weight percentage, the following raw materials: 1.5-32 parts silica powder, 1-10 parts HDI / trimethylolhexyl lactone crosspolymer modified silica, and 0.5-2 parts vinyl polydimethylsiloxane / polymethylsiloxane sesquioxane crosspolymer.

[0015] By adopting the above technical solution, silica powder has a certain oil-absorbing capacity. Using it in loose powder can give the powder a certain oil-control effect and improve its staying power. On the other hand, selecting HDI / trimethylolhexyl lactone crosspolymer and vinyl polydimethylsiloxane / polymethylsiloxane-silsesquioxane crosspolymer as filler raw materials can give the loose powder a certain degree of water resistance, reducing the possibility of makeup fading and further improving its staying power. This avoids makeup fading and dullness caused by prolonged wear. Furthermore, vinyl polydimethylsiloxane... Vinyl dimethylsiloxane / polymethylsiloxane silsesquioxane crosslinking polymer is an organosilicon elastic powder with excellent smoothness and elasticity. It can thicken and matte the skin while also increasing moisturizing effects. The addition of vinyl dimethylsiloxane / polymethylsiloxane silsesquioxane crosslinking polymer can not only work synergistically with silica to improve the oil absorption capacity of the powder, but also work together with HDI / trimethylolhexyl lactone crosslinking polymer to fill the grooves and pores on the skin surface, visually improving skin wrinkles without clogging pores, making the skin smooth, soft, and naturally translucent.

[0016] Optionally, the silica powder comprises 1-30 parts silica and 0.5-2 parts yeast fermentation material, based on its weight percentage in the loose powder.

[0017] By adopting the above technical solution, yeast fermentation products are used in the filler. The yeast fermentation products can be filled into HDI / trimethylolhexyl lactone crosspolymer modified silica, silica and other fillers, thereby releasing slowly. In addition, the yeast fermentation products are rich in various amino acids, sugars, minerals, vitamins and so on, which have a good repairing effect on the skin. Furthermore, it is weakly acidic, which can gently remove old keratin and achieve antioxidant and deep moisturizing effects.

[0018] Optionally, the yeast fermentation product includes a yeast fermentation broth and lauroyl lysine in a mass ratio of 1:3-5.

[0019] By adopting the above technical solution, lauroyl lysine is an amino acid derivative that not only has high lubricity, smooth skin feel, and low coefficient of friction, but also antistatic and antioxidant properties. When added to fillers together with yeast fermentation liquid, it gives fillers such as silica good skin feel, smoothness, and hydrophobicity, making the loose powder delicate, with strong skin feel, better performance, and waterproof and non-smudging properties.

[0020] Optionally, the yeast fermentation product also contains dioctyl carbonate and litchi peel extract, wherein the mass ratio of dioctyl carbonate, litchi peel extract and yeast fermentation broth is 0.5-1:0.2-0.4:1.

[0021] By employing the above technical solution, dioctyl carbonate possesses a relatively dry and delicate skin feel, spreads easily on the skin surface, has good breathability, and has low polarity, exhibiting good dispersibility for silica powder. It improves the dispersion effect of silica powder, thus forming a barrier on the skin, and is smooth and non-greasy, giving the loose powder a silky feel. Lychee peel extract contains phlorizin, whose hydrolysis product, phlorizin, can inhibit the activity of tyrosinase in melanocytes, interfering with melanin formation, thereby enhancing the whitening effect of the loose powder. It also has antioxidant properties. It promotes transdermal absorption, moisturizes, and inhibits bacteria. In addition, during the stirring process, phlorizin combines with yeast fermentation broth, Bifida ferment lysate, HDI / trimethylolhexyl lactone cross-linked polymer modified silica, and vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane cross-linked polymer. The large molecules formed by this binding force can prevent molecular aggregation due to steric hindrance, increase the binding force with the base makeup, maintain a certain degree of breathability, inhibit the secretion of oil molecules, and achieve an oil control effect.

[0022] Optionally, the mass ratio of the Bifida ferment lysate to the silica pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine is 4.5-5:1.

[0023] By adopting the above technical solution, the Bifida ferment lysate and 1,1,1-trimethyl-N-(trimethylsilyl)silane amine pretreated silica in the above mass ratio facilitate the encapsulation of the Bifida ferment lysate by the 1,1,1-trimethyl-N-(trimethylsilyl)silane amine pretreated silica, thereby enabling slow release and achieving the effect of keeping the skin moisturized at all times.

[0024] Optionally, the Bifida ferment filtrate comprises the following raw materials: 1-2 parts of Bifida ferment filtrate, 0.01-0.02 parts of 1,2-hexanediol, 0.001-0.002 parts of octanoyl hydroxamic acid, and 0.005-0.01 parts of p-hydroxyacetophenone.

[0025] By employing the above-mentioned technical solution, Bifida ferment lysate has a good skin-strengthening effect. Its main components are amino acids, organic acids, and cytoplasm, belonging to small molecule peptides, and it is rich in B vitamins. It can fundamentally resist and repair damaged skin, strengthen the skin barrier function, replenish the skin's required vitamins, brighten skin tone, awaken skin elasticity and vitality, regulate the skin's water-oil balance, and achieve long-lasting oil control.

[0026] Optionally, the Bifida ferment filtrate further includes walnut inner seed coat polyphenols and litchi leaf extract fermentation broth, wherein the mass ratio of the Bifida ferment filtrate, walnut inner seed coat polyphenols and litchi leaf extract fermentation broth is 1:0.3-0.5:0.1-0.3.

[0027] By adopting the above technical solution, walnut inner seed coat and lychee leaf extract, which are often discarded as byproducts, are added to the fermentation product of Bifida ferment lysate. The phenolic acid monomers in walnut inner seed coat polyphenols mainly include gallic acid, vanillic acid, chlorogenic acid, and caffeic acid, which can inhibit tyrosinase activity and have a significant effect on inhibiting melanin synthesis and scavenging free radicals. The fermentation broth of lychee leaf extract has a high whitening effect and can inhibit melanin synthesis, thereby further improving the whitening effect and anti-oxidation effect of loose powder.

[0028] Optionally, the litchi leaf extract fermentation broth is prepared by mixed fermentation of litchi leaf extract and Lactobacillus plantarum added at an amount of 0.5-1% of the mass of litchi leaf extract.

[0029] By adopting the above technical solution, the litchi leaf extract contains quercetin and kaempferol, which can inhibit melanin formation by inhibiting tyrosinase activity and the expression of melanin-related enzymes. The fermentation of Lactobacillus plantarum enhances the whitening effect of litchi leaf extract.

[0030] Optionally, the preservatives in phase D include phenoxyethanol and ethylhexylglycerin.

[0031] By adopting the above technical solution, ethylhexylglycerol affects the surface tension on the cell membrane of microorganisms, thereby improving the preservative ability of phenoxyethanol; it has a good inhibitory effect on bacteria, yeast and mold, and is a typical antibacterial and preservative product, while also having a certain bactericidal ability.

[0032] Secondly, this application provides a method for preparing a powder containing Bifida ferment filtrate, using the following technical solution:

[0033] A method for preparing a powder containing Bifida ferment filtrate includes the following steps:

[0034] Mix the A phase raw material evenly, add the D phase raw material, mix well, and obtain powder A;

[0035] Heat the B-phase raw material to 60-65℃, mix well, and obtain the solvent;

[0036] The solvent was added to phase C and mixed well to obtain powder B;

[0037] Mix powder A and powder B evenly to obtain loose powder.

[0038] By adopting the above technical solution, fillers, preservatives, and humectants are mixed to obtain powder A. Phase B raw materials and phase C raw materials are mixed, and silica is pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine to encapsulate the Bifida ferment lysate in phase B to obtain powder B. Powder B and powder A are mixed to make loose powder. No oil is added to avoid the poor compatibility between water-based active moisturizing ingredients and oils, which makes it difficult to form a powder with a uniform texture.

[0039] In summary, this application has the following beneficial effects:

[0040] 1. Because this application uses silica, yeast fermentation products, HDI / trimethylolhexyl lactone cross-linking polymer, and vinyl polydimethylsiloxane / polymethylsiloxane-silsesquioxane cross-linking polymer as fillers, and utilizes the special adsorption properties of silica pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine to encapsulate the Bifida ferment lysate, when the loose powder is applied, it first forms a delicate filling layer on the skin surface, making the skin delicate and smooth, achieving the effects of setting makeup, controlling oil, and increasing skin radiance. As the makeup wear time increases, the Bifida ferment lysate is slowly released, thereby achieving long-lasting moisturizing, keeping the skin hydrated at all times, and preventing the skin from experiencing makeup patchiness or caking due to long makeup wear time.

[0041] 2. In this application, it is preferred to add lychee peel extract and dioctyl carbonate to the yeast fermentation product, which can improve the lubricity of silica powder, making the loose powder easy to apply, light and breathable, and not clogging pores. It can also effectively resist the damage of ultraviolet rays to the skin, prevent melanin synthesis, and remove free radicals, thereby achieving the effects of whitening and anti-makeup oxidation.

[0042] 3. In this application, it is preferred to add walnut inner seed coat polyphenols and lychee leaf extract fermentation liquid to the Bifida ferment filtrate. This can inhibit tyrosinase activity and melanin synthesis to achieve a whitening effect. In addition, it can remove free radicals, making the loose powder have a good anti-oxidation effect and less likely to cause dull skin due to oxidation. Detailed Implementation

[0086] Performance testing

[0087] I. Oil control and long-lasting moisturizing effect test: The loose powder was prepared according to the methods in the examples and comparative examples, and the performance of the loose powder was tested with reference to the following methods. The test results are recorded in Table 2.

[0088] Maintaining constant ambient temperature and humidity, 20 subjects were selected. After facial cleansing, the T-zone of the face was divided into three areas. The initial value of skin oil content (μg / cm2) was measured. The unmade-up area served as the blank control group, and the area with evenly applied loose powder served as the experimental group. The amount of loose powder applied was 50±0.5mg. Skin oil content and hydration were measured at 2, 4, 6, and 8 hours. Skin oil content was measured using an NJ8-SHM100 skin oil analyzer, and hydration was measured using a German Courage+Khazaka CM825-MDD analyzer. Oil absorption rate was calculated using the following formula: Oil absorption rate (%) = (Oil content of blank group - Oil content of experimental group) / Oil content of blank group × 100%. The higher the oil absorption rate, the better the oil control effect. Maintaining a high oil absorption rate over a long period of time indicates a good long-lasting oil control effect. Higher hydration indicates a higher water content.

[0089] Table 2. Test results of the oil control and long-lasting moisturizing effects of loose powder.

[0090]

[0091]

[0092] As can be seen from the data in Table 1, in Examples 1 and 2, Bifida ferment lysate and 1,1-trimethyl-N-(trimethylsilyl)silaneamine were added to phases B and C respectively at mass ratios of 1:4.5 and 1:5, and silica, yeast ferment lysate, and HDI / trimethylolhexyl lactone crosspolymer modified silica were used as fillers. The resulting loose powder still achieved an oil absorption rate of over 55% after 8 hours, demonstrating excellent long-lasting oil control. Moreover, the skin's hydration level remained above 55% after 8 hours, indicating a good long-lasting moisturizing effect and preventing dryness and makeup smudging.

[0093] Compared with Example 1, Example 3 reduced the amount of yeast fermentation products added and increased the amount of silica used. As a result, the long-lasting moisturizing effect, oil control and makeup smudge prevention effect of the loose powder made in Example 3 were weakened.

[0094] In Example 4, silica was used instead of yeast fermentation products. Compared with Example 1, the oil control ability of the loose powder was weakened, and the long-lasting moisturizing effect was reduced.

[0095] In Example 5, a larger amount of silica was used as a filler, and no other raw materials were used as fillers. As can be seen from the data in Table 2, the oil control and long-lasting moisturizing effects of the loose powder made in Example 5 were significantly reduced, indicating that the combination of multiple components as fillers can improve the long-lasting oil control and constant moisturizing ability of the loose powder.

[0096] In Examples 6 and 7, dioctyl carbonate and litchi peel extract were added to the yeast ferment. Compared with Example 1, the loose powder prepared in Examples 6 and 7 had enhanced oil control effect, and the oil absorption rate after 8 hours was still higher than that in Example 1, indicating that the long-term oil control ability was also improved. In addition, the moisturizing effect of the loose powder was enhanced, and the long-term moisturizing ability was increased.

[0097] In Example 8, dioctyl carbonate was added only to the yeast ferment. Table 2 shows that the long-lasting oil-controlling effect of the loose powder was weakened, but the hydration level did not change much. This indicates that dioctyl carbonate can enhance the oil-controlling effect of the loose powder, but has little impact on the long-lasting moisturizing effect.

[0098] In Example 9, only lychee peel extract was added to the yeast ferment. The moisturizing effect of the loose powder prepared in Example 9 was weakened, but the oil control ability did not change much, indicating that the addition of lychee peel extract can improve the long-lasting moisturizing effect of the loose powder.

[0099] Compared with Example 7, Examples 10 and 11 also added walnut inner seed coat polyphenols and litchi leaf extract fermentation liquid to the Bifida ferment lysate. As shown in Table 2, the oil control and moisturizing effects of the loose powders prepared in Examples 10 and 11 are not much different from those in Example 7.

[0100] Compared to Example 7, Examples 12 and 13 added walnut inner seed coat polyphenols and litchi leaf extract fermentation broth to the Bifida ferment lysate, respectively. The oil absorption rate and hydration degree detected in Table 2 are similar to those of Examples 7 and 10-11.

[0101] In Comparative Example 1, silica was treated with hydroxydimethylsiloxane as the C phase. In Comparative Example 2, untreated silica was used instead of silica pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine. In Comparative Example 3, silica was not pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine. As can be seen from the data in Table 2, the oil control and moisturizing effect of Comparative Example 3 was not as good as that of Comparative Example 2. The oil control and moisturizing effects of Comparative Example 2 were not as good as those of Comparative Example 1. The oil control effect of Comparative Example 1 was not as good as that of Example 1. This shows that treating silica with silanes can improve the long-term oil control and moisturizing effects of silica. However, the choice of silane is more important. After treating silica with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine, its adsorption of Bifida ferment lysate can be improved, thereby improving the long-term oil control and moisturizing effects of the loose powder.

[0102] Compared with Example 1, Comparative Example 4 did not add Bifida Ferment Lysate. The data comparison in Table 2 shows that Bifida Ferment Lysate has a significant impact on the long-lasting moisturizing effect of the loose powder.

[0103] Comparative Example 5 is a raw material and preparation method for a loose powder provided by the prior art. Its oil absorption rate and hydration degree test values ​​are both lower than those of Example 1, indicating that the oil control and moisturizing effects of the loose powder are not as good as those of this application.

[0104] II. Whitening and Anti-makeup Oxidation Effect Test: Loose powder was prepared according to the methods in the examples and comparative examples, and the performance of the loose powder was tested with reference to the following methods. The test results are recorded in Table 3.

[0105] 1. Whitening Efficacy: Subjects with daily makeup needs were selected. Loose powder prepared according to the examples and comparative examples was used. Five subjects were selected for each example or comparative example. Before applying makeup, the skin melanin content of the subjects was measured using a skin melanin tester (CKMC-760, Germany) as the baseline value. The subjects applied makeup according to the normal makeup process every day. The duration of outdoor activities during the test period was consistent with the usual duration of outdoor activities. After 7 days of use, the change in the melanin content of the subjects' skin was measured. The melanin inhibition rate (%) before and after the subjects' use was calculated as follows: (pre-test value - post-test value) / pre-test value × 100%. The average value of each test was taken.

[0106] 2. Antioxidant effect: Weigh 1 mg of DPPH reagent, add 50 ml of anhydrous ethanol, and dissolve thoroughly to prepare DPPH-ethanol solution;

[0107] Experimental group: Add 0.05g of loose powder to 5ml of DPPH-ethanol solution, mix well, let stand in the dark at room temperature for 30min, and measure the absorbance value A1 at 517nm. Use the same method to test three times and take the average value.

[0108] Control group: Add 1ml of distilled water to 5ml of DPPH-ethanol solution, mix well, and follow the same procedure as the experimental group. Record the absorbance value as A0. Test three times and take the average value. Calculate the clearance rate according to the following formula: DPPH clearance rate = (A0-A1) / A1×100%; The higher the DPPH clearance rate, the better the anti-oxidation effect of the loose powder.

[0109] Table 3. Test results of the whitening and anti-oxidation effects of loose powder.

[0110] project Melanin inhibition rate / % DPPH removal rate / % Example 1 0.53 50.6 Example 2 0.51 50.3 Example 3 0.51 50.4 Example 4 0.50 50.6 Example 5 0.48 50.5 Example 6 0.86 54.5 Example 7 0.91 54.8 Example 8 0.52 50.7 Example 9 0.85 54.2 Example 10 1.49 59.6 Example 11 1.52 59.8 Example 12 1.25 58.5 Example 13 1.21 58.7 Comparative Example 1 0.51 50.2 Comparative Example 2 0.50 50.4 Comparative Example 3 0.50 50.1 Comparative Example 4 0.51 49.5 Comparative Example 5 0.21 49.2

[0111] As can be seen from the data in Table 3, the whitening effect and anti-makeup oxidation ability of the loose powder prepared in Examples 1-5 need to be improved. However, in Examples 6 and 7, dioctyl carbonate and lychee peel extract were added to the yeast fermentation product, which enhanced the whitening ability of the loose powder prepared in Examples 6 and 7 and improved the anti-makeup effect.

[0112] In Examples 8 and 9, dioctyl carbonate and litchi peel extract were added to the yeast fermentation product, respectively. The loose powder prepared in Example 8 showed a decrease in whitening and anti-oxidation effects, indicating that litchi peel extract can improve the whitening and anti-oxidation effects of the loose powder. The loose powder prepared in Example 9 showed little change in melanin inhibition rate and DPPH scavenging rate, indicating that dioctyl carbonate did not significantly improve the whitening and anti-oxidation effects of the loose powder.

[0113] Compared with Example 7, Examples 10 and 11 also added walnut inner seed coat polyphenols and litchi leaf extract fermentation liquid to the Bifida ferment lysate. As shown in Table 3, the SPF value and DPPH scavenging rate of the powder increased, indicating that the walnut inner seed coat polyphenols and litchi leaf extract fermentation liquid can improve the whitening and antioxidant capabilities of the powder.

[0114] Compared to Example 7, Examples 12 and 13 added walnut inner seed coat polyphenols and litchi leaf extract fermentation broth to the Bifida ferment lysate, respectively. As shown in Table 2, compared to Example 10, the powders prepared in Examples 12 and 13 showed a decrease in both antioxidant effect and whitening ability.

[0115] In Comparative Example 1, silica was treated with hydroxydimethylsiloxane as the C phase. In Comparative Example 2, untreated silica was used instead of silica pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine. In Comparative Example 3, silica pretreated with 1,1,1-trimethyl-N-(trimethylsilyl)silaneamine was not added. The anti-oxidation and whitening effects of the loose powder prepared in Comparative Examples 1-3 were not significantly different.

[0116] In Comparative Example 4, no Bifida ferment lysate was added. The resulting loose powder showed a decreased DPPH scavenging rate and weakened antioxidant capacity, but the whitening effect remained largely unchanged.

[0117] The loose powder prepared in Comparative Example 5 had lower SPF and DPPH removal rates, and its whitening and anti-makeup oxidation abilities were inferior to those of this application.

[0118] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
