Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cosmetics, in particular to a transparent scrubbing powder stick and a preparation method and application thereof. BACKGROUND

[0002] In the development process of the beauty industry, people's attention to skin care and beauty modification continues to increase. With the improvement of living standards, consumers' demand for beauty products is increasingly diversified, not only requiring the products to have basic beauty effects that can improve the appearance of the skin, but also expecting more convenience and comfort in the use process, bringing people more choices to enhance their own image and self-confidence, which further promotes the beauty market to continuously explore new products and technologies.

[0003] In the traditional beauty market, in order to improve the appearance of the skin, people usually adopt various ways. Among them, the physical scrub is one of the common choices, which removes the aging keratin on the surface of the skin through the friction of particles, so that the skin looks smoother. Chemical exfoliation products use chemical ingredients to dissolve keratin to achieve similar effects. In addition, some high-end skin care brands have launched serums or creams with slight scrubbing effects, and there are also beauty instruments combined with microdermabrasion technology for exfoliation and beauty in professional beauty institutions.

[0004] However, these methods have obvious defects. The size of the particles of ordinary scrubbing cream is difficult to control accurately, which can easily cause excessive irritation and damage to the skin, and the skin can also be dry after use. Chemical exfoliation products can cause allergic reactions, and need to be carefully washed after use, which is more cumbersome to operate. The serums or creams with slight scrubbing effects have thick texture and can leave a sticky feeling after application, and the scrubbing effect is limited. Beauty instruments are expensive and bulky, which are not convenient to carry and use, and cannot meet the needs of consumers to care for their skin anytime and anywhere. SUMMARY

[0005] In order to at least overcome one of the problems existing in the prior art, one of the purposes of the present application is to provide a transparent scrubbing powder stick which is moisturizing and non-sticky after use, has a scrubbing and modifying effect, and is convenient to carry, meeting the needs of consumers to care for their skin anytime and anywhere. The second purpose of the present application is to provide a preparation method of the transparent scrubbing powder stick. The third purpose of the present application is to provide an application of the transparent scrubbing powder stick.

[0006] To this end, the present application adopts the following technical solutions: The first aspect of the present application provides a transparent exfoliating powder stick, which raw material components include: moisturizing and emollient, film forming agent, skin feel modifier, emulsifier, viscosity modifier, stabilizer, antioxidant, preservative, odorant and colorant; the moisturizing and emollient is a mixture of at least two different chain length amino acyl compounds; the film forming agent is phenylsiloxane.

[0007] In the raw material components of the transparent exfoliating powder stick, the amino acyl compounds with different chain lengths can form a synergistic effect, which helps to quickly penetrate into the skin surface to moisturize and form a long-lasting moisturizing film on the skin surface, significantly improving the moisturizing durability and skin feel adaptability of the product; the phenylsiloxane has excellent film forming property and transparency, and can form a uniform and light-transmitting film on the skin surface after film forming, which not only meets the appearance requirements of the transparent powder stick, but also smooths fine lines and hides pores through the slight modification effect of the film, realizing the "exfoliating" effect; the components cooperate with each other, so that the transparent exfoliating powder stick of the present application is moisturizing and non-drying after use, has exfoliating modification effect, and has a refreshing and non-sticky skin feel, which meets the market demand of the exfoliating powder stick in the cosmetic field.

[0008] Preferably, the moisturizing and emollient is selected from at least two of dibutyl ethylhexyl glutamide, dibutyl lauroyl glutamide, sodium isostearoyl glutamate, sodium stearoyl glutamate, palmitoyl glycine, sodium cocoyl glutamate, and sodium lauroyl alaninate. Further preferably, the moisturizing and emollient is selected from at least two of dibutyl ethylhexyl glutamide, dibutyl lauroyl glutamide, sodium isostearoyl glutamate, sodium stearoyl glutamate, and sodium lauroyl alaninate. Still further preferably, the moisturizing and emollient is selected from at least two of dibutyl ethylhexyl glutamide, dibutyl lauroyl glutamide, and sodium isostearoyl glutamate.

[0009] Preferably, the moisturizing and emollient is a mixture of dibutyl ethylhexyl glutamide and dibutyl lauroyl glutamide, and the weight ratio of the dibutyl ethylhexyl glutamide to the dibutyl lauroyl glutamide is (1-1.5):1.

[0010] In the above technical solution, the moisturizing and emollient belongs to the amino acid derivative moisturizing agent, which has a similar structure to the amino acid of the skin keratin layer, has a natural skin-friendly property, and reduces the irritation of the transparent exfoliating powder stick to sensitive skin; on the other hand, the at least two different chain length amino acyl compounds play a performance synergistic complementary role, such as dibutyl ethylhexyl glutamide with 8 carbon atoms, which is easy to penetrate the skin and has a refreshing skin feel, and dibutyl lauroyl glutamide with 12 carbon atoms, which has strong water-locking ability, the combination of the two can achieve long-acting water-locking and refreshing and non-sticky skin feel, solving the problem that traditional moisturizing agents are sticky after long-term moisturizing, and refreshing but short-term moisturizing.

[0011] Preferably, the phenylsilicone is selected from at least one of phenyl trimethicone, polyphenylsilsesquioxane, diphenylsiloxy phenyl trimethicone. Further preferably, the phenylsilicone is selected from at least one of phenyl trimethicone, polyphenylsilsesquioxane. Still further preferably, the phenylsilicone is phenyl trimethicone.

[0012] The phenylsilicone has high light transmittance, good ductility, and fast film formation, and is tightly attached to the skin surface, and does not produce a false face when smoothing skin texture, achieving a natural exfoliation effect, high fusion with the skin, a light skin feel, and no whitening phenomenon after film formation, in line with the consumer orientation of fast exfoliation and a refreshing use. At the same time, the chemical properties of the phenylsilicone are relatively stable, and it is not easy to react with other components, prolonging the shelf life of the transparent exfoliation powder stick.

[0013] Preferably, the skin feel adjuster includes skin feel adjuster I and skin feel adjuster II, the skin feel adjuster I is a mixture of polydimethylsiloxane and polydimethylsiloxane / vinyl dimethicone crosspolymer in a weight ratio of (7-8):(2-3), and the skin feel adjuster II is a mixture of polydimethylsiloxane and polydimethylsiloxane crosspolymer in a weight ratio of (8-9):(1-2).

[0014] The polydimethylsiloxane in the skin feel adjuster I provides a basic refreshing feel, and the polydimethylsiloxane / vinyl dimethicone crosspolymer increases the silky feel of the skin feel, both reducing the tightness after use on dry skin, and not causing stickiness due to too much crosspolymer. The polydimethylsiloxane in the skin feel adjuster II has a higher proportion, and the crosspolymer has a lower proportion, and the skin feel is stronger, reducing the stickiness caused by easy oiling after use on oily skin, while the small amount of crosspolymer maintains the smoothness of the skin surface, avoiding the dryness caused by too much refreshing. The skin feel adjuster I and the skin feel adjuster II together achieve skin feel adaptation for different skin types, expanding the range of people who can use the product.

[0015] Preferably, the emulsifier is selected from at least one of polyglyceryl-10 pentaisostearate, polyglyceryl-3 diisostearate, polyglyceryl-4 isostearate, polyglyceryl-6 distearate, sorbitan sesquioleate, PEG-30 dipolyhydroxystearate. Further preferably, the emulsifier is selected from at least one of polyglyceryl-10 pentaisostearate, polyglyceryl-3 diisostearate, polyglyceryl-4 isostearate, polyglyceryl-6 distearate, sorbitan sesquioleate. Still further preferably, the emulsifier is selected from at least one of polyglyceryl-10 pentaisostearate, polyglyceryl-3 diisostearate, polyglyceryl-4 isostearate.

[0016] Preferably, the viscosity adjuster is a synthetic wax.

[0017] Preferably, the synthetic wax is selected from at least one of polyethylene wax, oxidized polyethylene wax, Sasol wax, Honeywell wax powder. Further preferably, the synthetic wax is selected from at least one of polyethylene wax, oxidized polyethylene wax, Sasol wax. Still further preferably, the synthetic wax is selected from at least one of polyethylene wax, oxidized polyethylene wax.

[0018] The emulsifier in the above technical solution has a more refreshing and less irritating skin feel, belongs to a low HLB value emulsifier, has a much greater lipophilicity than hydrophilicity, is more compatible with oil components such as film-forming agents, moisturizing and emollient agents, and uniformly disperses the oil components, thereby avoiding problems such as local clumping and reduced stability of the product.

[0019] The melting point of the synthetic wax is relatively fixed, and is used to adjust the viscosity of the transparent exfoliating stick, which ensures that the stick is in a rod-shaped solid state at room temperature and is not prone to breaking, and can be smoothly formed into a film at the time of application due to body temperature melting, thereby avoiding the problems of easy softening in summer and easy brittle cracking in winter caused by unstable melting point of natural wax. In addition, the synthetic wax has high light transmittance and will not affect the transparency of the product after being added.

[0020] Preferably, the stabilizer is selected from at least one of hydrogenated polyisobutylene, hydrogenated polydecene, tridecanol trimellitate. Further preferably, the stabilizer is selected from at least one of hydrogenated polyisobutylene, hydrogenated polydecene.

Still further preferably, the preservative is a mixture of phenoxyethanol and octoxinol in a weight ratio of 6.5:3.5.

[0023] Preferably, the fragrance is selected from at least one of methyl vanillin, ethyl vanillin, eugenol, linalool, cinnamaldehyde. Further preferably, the fragrance is selected from at least one of methyl vanillin, ethyl vanillin, eugenol, linalool. Still further preferably, the fragrance is selected from at least one of methyl vanillin and ethyl vanillin.

[0024] Preferably, the colorant is selected from at least one of CI 42090, CI 19140, CI 15850, CI 77499, CI 77492, CI 77491, CI 77891. Further preferably, the colorant is a mixture of CI 42090, CI 19140, CI 15850, CI 77499, CI 77492, CI 77491, CI 77891.

[0025] Preferably, in the colorant, the weight fraction ratio of CI 42090, CI 19140, CI 15850, CI 77499, CI 77492, CI 77491, CI 77891 is (0.1-1):(0.1-1):(0.1-1):(0.1-1):(0.1-1):(0.1-1):(0.1-1).

[0026] In the above technical solution, the stabilizer is an oil-soluble carrier with high stability, which can wrap components such as film-forming agents and moisturizing and emollient agents to prevent molecular aggregation or decomposition caused by changes in external factors such as temperature and light during storage, thereby extending the shelf life of the product. The antioxidant is beneficial to inhibit the oxidation of moisturizing and emollient agents, film-forming agents, etc., and avoid skin irritation caused by oxidation products. The preservative formed by the mixture of phenoxyethanol and octisalate forms a synergistic preservative system, in which phenoxyethanol mainly achieves efficient inhibition of bacteria by destroying bacterial cell membrane structure and inhibiting bacterial metabolic enzyme activity; octisalate inhibits fungal growth by changing the permeability of fungal cell membranes and interfering with fungal cell wall synthesis. The two have clear division of labor, covering both bacteria and fungi, and octisalate can reduce the irritation of phenoxyethanol. The selected odorant has a mild and long-lasting odor that can mask the slight odor of the raw material components and improve the pleasantness of product use. The colorant does not destroy the transparency of the transparent scrubbing powder stick, but can enhance its modification of the scrubbing effect, such as hiding and darkening through skin color correction.

[0027] Preferably, in the raw material of the transparent scrubbing powder stick, the weight fraction ratio of the moisturizing and emollient agent, the film-forming agent, the skin feel modifier, the emulsifier, and the viscosity modifier is (4-6):(30-35):(40-60):(1-2):(0.1-1).

[0077] 3. Cold and hot cycle: freeze at -10°C for 24 h, place at 40°C for 24 h, and cycle 3 times, and observe whether the product melts, cracks, and whether it returns to the original form after cooling.

[0078] 4. Randomly select 25 women to test the moisturizing degree, softening degree, and scrubbing modification effect after use, and the specific method is as follows: Apply equal amounts of the transparent scrubbing powder stick samples of Examples 1-7 and Comparative Examples 1-3 to the left and right cheeks, respectively, and score the moisturizing degree, 1-10 points, 10 points for moisturizing, and 1 point for completely not moisturizing.

[0079] Apply equal amounts of the transparent scrubbing powder stick samples of Examples 1-7 and Comparative Examples 1-3 to the left and right cheeks, respectively, and score the softening degree, 1-10 points, 10 points for smooth and soft, and 1 point for very sticky.

[0080] Apply equal amounts of the transparent scrubbing powder stick samples of Examples 1-7 and Comparative Examples 1-3 to the left and right cheeks, respectively, and then carefully observe the changes in the pores of the left and right cheeks, and score the scrubbing modification effect, 10 points for very effective, invisible pores; 8 points for very effective, relatively invisible pores; 6 points for effective, relatively invisible pores; 4 points for a little effective, relatively large pores; 2 points for no effect, large pores.

[0081] The tester scores according to the above scoring standard, and finally calculates the average value of all scores.

[0082] The test performances of the transparent scrubbing powder sticks of Examples 1-7 and Comparative Examples 1-3 are shown in Table 1 below: Table 1 Test results of the performances of Examples 1-7 and Comparative Examples 1-3 The transparent scrubbing powder sticks of Examples 1-7 have high stability, strong heat and cold resistance, and after use, they are not dry, have scrubbing and modifying effects, and have a refreshing and non-sticky skin feel, are convenient to carry, and meet the needs of consumers for skin care anytime and anywhere.

[0083] Comparative Example 1 has the same preparation method and amounts of raw materials as Example 1, except that the moisturizing and emollient agent in Comparative Example 1 is prepared according to Comparative Example 1. The results show that the moisturizing degree of the powder stick of Comparative Example 1 is reduced to 7.1 points, and the emollience is only 7.6 points. This may be because the content of the long-chain component, i.e., dibutyl lauroyl glutamine, in the moisturizing and emollient agent is too high, the skin penetration is slow, and stickiness is easily produced.

[0084] Comparative Example 2 has the same preparation method and amounts of raw materials as Example 1, except that the amount of the film-forming agent phenyl trimethicone in Comparative Example 2 is 28 g. The results show that the heat resistance test of the powder stick of Comparative Example 2 appears to be slightly softened, and deformation occurs after cold and hot cycles, and the scrubbing effect is reduced to 7.2 points. This may be due to the insufficient amount of the film-forming agent phenyl trimethicone in the raw materials of Comparative Example 2, which causes incomplete film-forming effect.

[0085] Comparative Example 3 has the same preparation method and amounts of raw materials as Example 1, except that the skin feel regulator in Comparative Example 3 is prepared according to Comparative Example 2. The results show that the emollience of the powder stick of Comparative Example 3 is reduced to 6.8 points. This may be due to the excessive amount of skin feel regulator I cross-linked polymer and the insufficient amount of skin feel regulator II refreshing component in the skin feel regulator of Comparative Example 3, which enhances the stickiness of the prepared transparent scrubbing powder stick.
