Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, and in particular relates to a spray-type highlighting eyeshadow and its preparation process. Background Technology

[0002] Eyeshadow cosmetics use shadows to sculpt the contours of the eyes. Darker eyeshadow is applied to the eyelids, followed by lighter eyeshadow on the brow bone to make the eyes appear more vibrant. When using eyeshadow, attention should be paid to the harmony between the eyeshadow and the skin tone, and it should complement the color scheme of the clothing worn.

[0003] However, existing eyeshadows are prone to powder fallout, have loose powder particles with poor adhesion, produce a lot of dust during application, waste raw materials, and are likely to irritate the eyes; they tend to clump and form lines after absorbing oil, easily clumping and settling in the eyelid creases, resulting in an unclean makeup look; they have uneven color rendering and patchy appearance, with powder particles of varying coarseness, making it difficult to control powder pickup and resulting in inconsistent color depth; they feel heavy on the skin, with too much suffocating powder or film-forming agent, creating a heavy feeling during application and poor breathability; they are not easy to blend, have harsh edges, and are too tightly or too loosely pressed powder, making it difficult to pick up powder with a brush and resulting in weak makeup staying power. Summary of the Invention

[0004] To address the aforementioned technical problems, the objective of this invention is to propose a spray-type highlighting eyeshadow and its preparation process.

[0005] The technical solution of this invention is implemented as follows:

[0006] A spray-on highlighter eyeshadow contains the following raw material components:

[0007] Phase A

[0008] SOLEON F1014 (Vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosslinked polymer) 5%-8%;

[0009] Organosilicon elastic powder HSP3310 (polydimethylsiloxane / vinyl polydimethylsiloxane cross-linked polymer, silica) 3%-5%;

[0010] Phase B

[0011] Phenoxyethanol 0.5%-1%;

[0012] Ethylhexylglycerin 0.1%-0.5%;

[0013] Centella asiatica extract 0.005%-0.015%;

[0014] POLYSYNLANE (hydrogenated polyisobutylene, tocopherol (vitamin E)) 0.5%-2.5%;

[0015] C phase

[0016] COSMI 151 Shining Pearl (Mica, CI77891, Tin Oxide) 48%-50%;

[0017] COSMI 870-W Super Glitter Penguin White (Synthetic Fluorophytite, CI77891, Tin Oxide) 19%-21%;

[0018] COSMI 980-W 3D Glittering Diamond White (Calcium Aluminum Borosilicate, CI77891, Tin Oxide) 9%-11%;

[0019] Kingsica 5020 AS (Silica, Triethoxyoctylsilane) 7%-9%.

[0020] A manufacturing process for a spray-on highlighter eyeshadow includes the following steps:

[0021] Step 1, Powder dispersion: Put phase A into a pulverizer and stir at high speed of 2600-2900 rpm for 1 minute once. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at high speed once more at 2600-2900 rpm for 1 minute once.

[0022] Step 2, Oil Spraying: Heat phase B in a sterilized clean stainless steel container to 70-80℃, then transfer it to an oil spraying can. Spray phase B from the oil spraying can into the pulverizer containing phase A from step 1. Stir at medium speed (1500-1800 rpm, 1 min x 1). Open the lid and clean from the lid to the bottom of the pot to ensure there are no oil residues on the edges. Close the lid and stir at high speed (2600-2900 rpm, 1 min x 1).

[0023] Step 3, Pearl dispersion: Add phase C to the pulverizer containing the mixture of phase A and phase B from step 2 and stir at medium speed for 1500-1800 rpm, 1 min*1 time. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at medium speed again for 1500-1800 rpm, 1 min*1 time.

[0024] Step four: Discharge the material after it meets the required quality standards.

[0025] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] This invention creates a spray-type highlighting eyeshadow through a specific formulation. The formula rapidly and evenly combines the mixed powder and liquid phase in specialized equipment to form an oil-based powder. This ensures that each powder particle is coated with an extremely thin oil film, without the overall product becoming a "wet" paste. Mica, along with pigments and pearlescent agents responsible for color development, makes the powder smooth and fine, avoiding a grainy feel when spraying. It combines the color payoff and long-lasting effect of powder with the uniformity and blendability of liquid. A unique spray technology, combined with a special packaging structure, atomizes and sprays the powder upon pressing, preventing flyaways. The powder remains stably suspended and sprays smoothly, ensuring an instant, refined makeup effect upon contact with the skin. It applies smoothly and without brush marks, offering excellent spreadability and a pleasant skin feel. Attached Figure Description

[0047] A manufacturing process for a spray-on highlighter eyeshadow includes the following steps:

[0048] Step 1, Powder dispersion: Put phase A into a pulverizer and stir at high speed of 2600-2900 rpm for 1 minute once. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot.

[0049] Step 2, Oil Spraying: Heat phase B in a sterilized clean stainless steel container to 70-80℃, then transfer it to an oil spraying can. Spray phase B from the oil spraying can into the pulverizer containing phase A from step 1. Stir at medium speed (1500-1800 rpm, 1 min x 1). Open the lid and clean from the lid to the bottom of the pot to ensure there are no oil residues on the edges. Close the lid and stir at high speed (2600-2900 rpm, 1 min x 1).

[0050] Step 3, Pearl dispersion: Add phase C to the pulverizer containing the mixture of phase A and phase B from step 2 and stir at medium speed for 1500-1800 rpm, 1 min*1 time. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at medium speed again for 1500-1800 rpm, 1 min*1 time.

[0051] Step four: Discharge the material after it meets the required quality standards.

[0052] This invention is a spray-type highlighting eyeshadow that combines the form of solid powder with the powder dispensing method of spray, that is, a powder eyeshadow that is "sprayed".

[0053] Its core features are as follows:

[0054] Form and principle: It is in powder form. The powder is formed by a special packaging structure to form a unique jet technology. When pressed, the powder can be atomized and sprayed out. It combines the color rendering and long-lasting effect of powder with the uniformity and easy blending of liquid.

[0055] Its core advantage lies in its extremely fast makeup application, creating a professional airbrush-like finish (without brush strokes and a delicate texture), while also solving the problem of fallout and making it easy to control the boundaries of color blocks.

[0056] Shake well before use. Spray at a distance of about 10-15 cm from the eyelid. For more precise makeup application, spray onto a makeup palette or your hand first, then use a brush to apply the product.

[0057] The preparation of "solid powder spray eyeshadow" is an interdisciplinary technology that combines traditional powder formulation technology with modern aerosol canning technology; it is necessary to ensure that the powder can be stably suspended and smoothly sprayed out, and to ensure that the powder can be instantly transformed into a delicate makeup effect when it comes into contact with the skin.

[0058] This technology mainly consists of two parts:

[0059] 1. Core formulation technology: The balance between powder and liquid, which is the product's "powder particles" that determine the makeup effect, skin feel, and lasting power.

[0060] The powder component makes up the largest proportion of the eyeshadow and constitutes the main body of the product. The powder includes mica, which provides a smooth feel, as well as pigments and pearlescent agents, which are responsible for color rendering. The powder must be fine enough to avoid a grainy feel when spraying. At the same time, in order for the powder to adhere to the skin and not fall out, a small amount of oily ingredients (such as silicone oil and esters) and emollients need to be added. The content of these liquid ingredients needs to be extremely precise to ensure that the powder does not clump in the container and that it has good adhesion and spreadability on the skin.

[0061] The product material is drawn into the nozzle by a circulating compressed airbag and then sprayed out. The overall formulation needs to ensure that the powder can be evenly suspended in the propellant, rather than sinking to the bottom or clogging the nozzle.

[0062] 2. Unique preparation process: From powder to spray, this is the "face" of the product, determining how it is ultimately presented and used.

[0063] Material preparation: First, powder premixing: all powder raw materials are put into a special mixer and broken down and mixed into an absolutely uniform powder without particle agglomeration through high-speed shearing, ensuring a delicate foundation for makeup effect; Second, liquid phase preparation: oily binders, moisturizers and other liquid ingredients are precisely mixed to form a uniform liquid phase; Finally, "dry and wet" combination: the mixed powder and liquid phase are quickly and uniformly combined in special equipment. This process is very critical, to ensure that each powder particle is coated with an extremely thin oil film, but the whole thing does not become a "wet" paste.

[0064] Material filling powder atomizer: This is the core difference from the traditional powder pressing process. The above-mentioned "oil-containing powder" is filled into an aluminum can with a valve system through special equipment; then, a propellant (such as nitrogen) is filled through another set of equipment and the can opening is sealed; finally, the nozzle that the user presses is installed, and a series of strict quality tests are carried out, such as spray volume, atomization effect, and whether the nozzle is blocked.

[0065] In summary, the challenge of this technology lies in maintaining a delicate balance between "dry and wet": inside the can, it must be a "dry powder" that can be stably suspended; when sprayed, it must be a fine and even "mist"; and after landing on the skin, it must quickly transform into a skin-adhering and color-enhancing "film".

[0066] Based on the above description, the present invention first selected a matching packaging material structure that can atomize the raw material particle size. All powder raw materials used in the following implementation schemes have a particle size of less than 15 micrometers. After selecting the raw materials, the following three implementation schemes were carried out.

[0067] The specific implementation examples are as follows:

[0068] Example 1

[0069] Phase A

[0070] SOLEON F1014 (vinyl polydimethylsiloxane / polymethylsiloxane sesquioxane crosslinked polymer) 6.0%;

[0071] Organosilicon elastic powder HSP3310 (polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, silica) 4.0%;

[0072] Phase B

[0073] Phenoxyethanol 0.8%;

[0074] Ethylhexylglycerin 0.2%;

[0075] Centella asiatica extract 0.01%;

[0076] POLYSYNLANE (hydrogenated polyisobutylene, tocopherol (vitamin E)) 2.0%;

[0077] C phase

[0078] COSMI 151 Shining Pearl (Mica, CI77891, Tin Oxide) 49.03%;

[0079] COSMI 870-W Super Glitter Penguin White (Synthetic fluorophlogopite, CI77891, tin oxide) 20.0%;

[0080] COSMI 980-W 3D Glittering Diamond White (Calcium Aluminum Borosilicate, CI77891, Tin Oxide) 10.0%;

[0081] Kingsica 5020 AS (silica, triethoxyoctylsilane) 7.96%.

[0082] The preparation process of the spray-type highlighting eyeshadow in Example 1 includes the following steps:

[0083] Step 1, Powder dispersion: Put phase A into a pulverizer and stir at high speed of 2600-2900 rpm for 1 minute once. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at high speed once more at 2600-2900 rpm for 1 minute once.

[0084] Step 2, Oil Spraying: Heat phase B in a sterilized clean stainless steel container to 70-80℃, then transfer it to an oil spraying can. Spray phase B from the oil spraying can into the pulverizer containing phase A from step 1. Stir at medium speed (1500-1800 rpm, 1 min x 1). Open the lid and clean from the lid to the bottom of the pot to ensure there are no oil residues on the edges. Close the lid and stir at high speed (2600-2900 rpm, 1 min x 1).

[0085] Step 3, Pearl dispersion: Add phase C to the pulverizer containing the mixture of phase A and phase B from step 2 and stir at medium speed for 1500-1800 rpm, 1 min*1 time. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at medium speed again for 1500-1800 rpm, 1 min*1 time.

[0086] Step four: Discharge the material after it meets the required quality standards.

[0087] The material obtained through Example 1 above is filled into packaging materials, such as... Figure 1 As shown, the spraying effect is relatively poor, but it can be sprayed out, indicating that the particle size of the raw material used is sufficient to fill the packaging material. The formula ratio needs to be adjusted to reduce the oil content in order to improve the spraying effect. Therefore, Example 2 was carried out.

[0088] Example 2

[0089] Phase A

[0090] SOLEON F1014 (vinyl polydimethylsiloxane / polymethylsiloxane sesquioxane crosslinked polymer) 6.0%;

[0092] Phase B

[0093] Phenoxyethanol 0.8%;

[0094] Ethylhexylglycerin 0.2%;

[0095] Centella asiatica extract 0.01%;

[0096] POLYSYNLANE (hydrogenated polyisobutylene, tocopherol (vitamin E)) 1.0%;

[0101] Kingsica 5020 AS (silica, triethoxyoctylsilane) 8.96%.

[0102] The preparation process of the spray-type highlighting eyeshadow in Example 2 includes the following steps:

[0103] Step 1, Powder dispersion: Put phase A into a pulverizer and stir at high speed of 2600-2900 rpm for 1 minute once. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at high speed once more at 2600-2900 rpm for 1 minute once.

[0104] Step 2, Oil Spraying: Heat phase B in a sterilized clean stainless steel container to 70-80℃, then transfer it to an oil spraying can. Spray phase B from the oil spraying can into the pulverizer containing phase A from step 1. Stir at medium speed (1500-1800 rpm, 1 min x 1). Open the lid and clean from the lid to the bottom of the pot to ensure there are no oil residues on the edges. Close the lid and stir at high speed (2600-2900 rpm, 1 min x 1).

[0105] Step 3, Pearl dispersion: Add phase C to the pulverizer containing the mixture of phase A and phase B from step 2 and stir at medium speed for 1500-1800 rpm, 1 min*1 time. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at medium speed again for 1500-1800 rpm, 1 min*1 time.

[0106] Step four: Discharge the material after it meets the required quality standards.

[0107] The material of Example 2 above was obtained by reducing the amount of POLYSYNLANE (hydrogenated polyisobutylene, tocopherol (vitamin E)) and increasing the amount of Kingsica5020 AS (silica, triethoxyoctylsilane), as shown above. Figure 2 As shown, when filled into the packaging material, the spray effect was significantly improved, but there was still a slight excess of oil. At the same time, it was found that the makeup lasting power was slightly worse, so Example 3 was implemented.

[0108] Example 3

[0109] Phase A

[0110] SOLEON F1014 (vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosslinked polymer) 6.8%;

[0111] Organosilicon elastic powder HSP3310 (polydimethylsiloxane / vinyl polydimethylsiloxane crosslinked polymer, silica) 4.0%;

[0112] Phase B

[0113] Phenoxyethanol 0.8%;

[0114] Ethylhexylglycerin 0.2%;

[0115] Centella asiatica extract 0.01%;

[0116] POLYSYNLANE (hydrogenated polyisobutylene, tocopherol (vitamin E)) 0.8%;

[0117] C phase

[0118] COSMI 151 Shining Pearl (Mica, CI77891, Tin Oxide) 49.03%;

[0119] COSMI 870-W Super Glitter Penguin White (Synthetic fluorophlogopite, CI77891, tin oxide) 20.0%;

[0120] COSMI 980-W 3D Glittering Diamond White (Calcium Aluminum Borosilicate, CI77891, Tin Oxide) 10.0%;

[0121] Kingsica 5020 AS (silica, triethoxyoctylsilane) 8.36%.

[0122] The preparation process of the spray-type highlighting eyeshadow in Example 3 includes the following steps:

[0123] Step 1, Powder dispersion: Put phase A into a pulverizer and stir at high speed of 2600-2900 rpm for 1 minute once. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at high speed once more at 2600-2900 rpm for 1 minute once.

[0124] Step 2, Oil Spraying: Heat phase B in a sterilized clean stainless steel container to 70-80℃, then transfer it to an oil spraying can. Spray phase B from the oil spraying can into the pulverizer containing phase A from step 1. Stir at medium speed (1500-1800 rpm, 1 min x 1). Open the lid and clean from the lid to the bottom of the pot to ensure there are no oil residues on the edges. Close the lid and stir at high speed (2600-2900 rpm, 1 min x 1).

[0125] Step 3, Pearl dispersion: Add phase C to the pulverizer containing the mixture of phase A and phase B from step 2 and stir at medium speed for 1500-1800 rpm, 1 min*1 time. Open the lid and sweep from the lid to the bottom of the pot to ensure that there are no sharp edges or residual powder in the pot. Close the lid and stir at medium speed again for 1500-1800 rpm, 1 min*1 time.

[0126] Step four: Discharge the material after it meets the required quality standards.

[0127] The material of Example 3 above was obtained by reducing the amount of POLYSYNLANE (hydrogenated polyisobutylene, tocopherol (vitamin E)) and Kingsica 5020 AS (silica, triethoxyoctylsilane) and increasing the amount of SOLEON F1014 (vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosspolymer). Figure 3 As shown, when filled into the packaging material, the spray effect is very uniform and the makeup lasts significantly better, with no powder falling off. This indicates that the oil content decreased by 0.2% and the film-forming setting agent (SOLEON F1014) increased by 0.8%, making the overall formula effect optimal. Ultimately, Example 3 was determined to be the best.

[0128] This invention addresses the shortcomings of the prior art and offers the following advantages: This invention provides a spray-type highlighting eyeshadow and its preparation process. The formula rapidly and uniformly combines a mixed powder with a liquid phase in specialized equipment to form an oil-containing powder. This ensures that each powder particle is coated with an extremely thin oil film, while preventing the overall product from becoming a "wet" paste. Mica, along with colorants and pearlescent agents responsible for color development, makes the powder smooth and fine, avoiding a grainy feel when spraying. It combines the color rendering and long-lasting properties of powder with the uniformity and easy blending advantages of liquid. Furthermore, a unique spray technology is achieved through a special packaging structure. Upon pressing, the powder is atomized and sprayed out without flying powder. The powder remains stably suspended and sprays smoothly, ensuring that it instantly transforms into a refined makeup effect upon contact with the skin. It is also smooth and leaves no brush marks on the skin, with good spreadability and a pleasant feel.

[0129] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
