Description

Technical Field

[0001] The invention belongs to the technical field of daily cosmetics, and particularly relates to a soft emulsified composition and application thereof. Background Art

[0002] Emulsification technology is a common synthetic technique in cosmetic formulations, often used in lotions, creams, and other cosmetics. The emulsification system primarily consists of the following components: The oil phase: Contains oils, waxes, esters, and other ingredients, providing moisturizing and hydration. Common ingredients include vegetable oils, silicone oils, and fatty alcohols. The aqueous phase: Contains water, humectants, and thickeners, providing hydration and moisturizing. Common ingredients include water, glycerin, and butylene glycol. Emulsifiers: Connect the oil and aqueous phases to form a stable emulsion. As a key component of cosmetic raw materials, they provide emulsification, dispersion, solubilization, lubrication, softening, and stabilization. Common ingredients include Tween, Span, and lecithin.

[0003] The principle of emulsification is that the hydrophilic and lipophilic groups in the emulsifier molecules reduce the interfacial tension between the oil and water phases, allowing the oil and water phases to disperse evenly and form a stable emulsion. Common emulsification systems include water-in-oil (W / O) and oil-in-water (O / W). W / O emulsions are highly moisturizing and have a thicker texture, making them suitable for dry skin. In contrast, O / W emulsions are lightweight, easy to apply, and refreshing, non-greasy, making them suitable for all skin types and popular with consumers. The emulsification system is the core of formulations for creams and lotions, directly affecting the product's skin feel, texture, stability, and efficacy. Therefore, selecting the right emulsifier is an essential and fundamental step in the development of cosmetics.

[0004] However, although cosmetic emulsification technology is becoming more and more mature, there are still some problems. First, some emulsification systems have stratification and flocculation problems. For example, after long-term storage or long-term exposure to high and low temperatures, the oil phase and the water phase may separate, resulting in product stratification or flocculation; second, there is the problem of skin feel. The combination of emulsifiers has a great influence on skin feel and texture. Due to the characteristics of their molecular structure, some emulsifiers feel sticky and greasy on the skin, and the texture is relatively rough, not delicate and soft enough. The emulsification particle size of some emulsification systems is large, which will lead to slower skin absorption; the third is the problem of efficacy and performance. The emulsifiers and emulsification systems currently on the market generally only have emulsification functions, no efficacy effects, and no auxiliary or improvement effects on the efficacy and performance of the formula system; the fourth is the safety issue. Some lotions or creams on the market will add some raw materials with safety risks, such as glyceryl stearate, stearic acid, isostearic acid, cyclopentasiloxane, etc., to provide the product with a delicate, soft, easy-to-spread, and easy-to-absorb skin feel. However, the addition of these raw materials may cause skin or eye irritation problems and are not suitable for infants or people with sensitive skin. In summary, there is an urgent need to provide an emulsification product with excellent emulsification properties, more comprehensive efficacy, and safety to meet application needs. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a soft emulsified composition and its application. The composition provided by the present invention has excellent emulsification power, small emulsified particle size, good stability, and can assist and enhance moisturizing, soothing, repairing and other functional effects through scientific combination. In addition, the emulsified composition of the present invention also has a special sustained-release technology, which can not only slow down the permeability of the functional ingredients, but also ensure the effective release of the functional ingredients.

[0006] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present invention provides a softening emulsion composition, comprising cetearyl alcohol, cetearyl glucoside, polysorbate 60, squalane, and hydrogenated coconut glycerides.

[0008] In the composition of the present invention, the cetearyl alcohol and cetearyl glucoside can replace the ethoxylated groups that are one of the characteristics of traditional nonionic surfactants. The structure is composed of hydrophilic glycosides and lipophilic coconut oil chains. Cetearyl alcohol and cetearyl glucoside are natural plant-derived ingredients extracted from coconut oil and glucose, and have good mildness and safety. Squalane is derived from plant fermentation and can form a skin-friendly protective film on the skin surface, preventing water loss, with a deep moisturizing effect, can improve the skin's ability to absorb moisture and other nutrients, and repair the skin's barrier function. The hydrogenated coconut glycerides are natural plant-derived, mild and non-irritating, with a melting point close to body surface temperature, and have a soft, melt-in, and comfortable, smooth skin feel. The special glycoside structure and polyoxyethylene group show outstanding emulsification properties and compatibility with various oil phases, and can emulsify various difficult-to-emulsify oils. The polysorbate-60 not only acts as an emulsion stabilizer, but is also often present as a moisturizing and hydrating ingredient. It can combine water and oil substances to form a stable emulsion system.

[0009] The soft emulsified composition of the present invention, through the combination of the above components, not only contains polyoxyethylene groups but also possesses a unique glycoside structure. It exhibits outstanding emulsifying properties and compatibility with various oil phases, capable of emulsifying a wide range of difficult-to-emulsify oils. It also possesses high chemical stability and resists degradation even in strong acidic or alkaline media. When applied to cosmetics, it exhibits excellent cosmetic qualities, is easy to use, has a soft touch, a smooth appearance, melts on contact, and has a cotton-like feel.

[0010] In addition, the soft emulsion composition of the present invention can form skin moisturizing molecules with a liquid crystal structure at the O / W interface, which can limit transepidermal water loss and prevent epidermal dehydration, thereby having a moisturizing effect. Therefore, it has good moisturizing, nourishing and repairing effects, and can help enhance the moisturizing and nourishing effect of the formula system.

[0011] Preferably, the softening emulsion composition comprises, by weight, 25-45 parts of cetearyl alcohol, 1-10 parts of cetearyl glucoside, 1-15 parts of polysorbate 60, 5-45 parts of squalane, and 10-50 parts of hydrogenated coconut glycerides.

[0012] The amount of cetearyl alcohol added to the soft emulsified composition of the present invention can be 26 parts, 28 parts, 30 parts, 32 parts, 35 parts, 38 parts, 40 parts, 42 parts or 44 parts.

[0013] The added amount of the cetearyl glucoside can be 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts or 9 parts, etc.

[0014] The added amount of the polysorbate 60 can be 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts or 14 parts, etc.

[0015] The amount of squalane added can be 6 parts, 8 parts, 10 parts, 12 parts, 15 parts, 18 parts, 20 parts, 22 parts, 25 parts, 28 parts, 30 parts, 32 parts, 35 parts, 38 parts, 40 parts, 42 parts or 44 parts, etc.

[0016] The added amount of the hydrogenated coconut glycerides can be 11 parts, 13 parts, 15 parts, 18 parts, 20 parts, 22 parts, 25 parts, 28 parts, 30 parts, 32 parts, 35 parts, 38 parts, 40 parts, 42 parts, 45 parts, 47 parts or 49 parts, etc.

[0017] Preferably, the mass ratio of the cetearyl alcohol to hydrogenated coconut glycerides is 1:(0.3-1.5), for example, it can be 1:0.4, 1:0.5, 1:0.6, 1:0.7, 1:0.8, 1:0.9, 1:1, 1:1.1, 1:1.2, 1:1.3 or 1:1.4, etc.

[0018] Any specific point value within the above numerical range can be selected and will not be described in detail here.

[0019] In a second aspect, the present invention provides a method for preparing the soft emulsion composition as described in the first aspect, the preparation method comprising: heating cetearyl alcohol, cetearyl glucoside, polysorbate 60, squalane and hydrogenated coconut glycerides to 80-100° C., mixing, and homogenizing to obtain the soft emulsion composition.

[0020] Here, "80-100℃" can be 81℃, 83℃, 85℃, 88℃, 90℃, 93℃, 95℃, 97℃ or 99℃, etc.

[0021] Any specific point value within the above numerical range can be selected and will not be described in detail here.

[0022] In a third aspect, the present invention provides a use of the soft emulsified composition according to the first aspect in preparing cosmetics;

[0023] The cosmetics include any one of essence, gel, jellies, creams or lotions.

[0027] The present invention's facial cream, prepared by adding a soft emulsifying composition, possesses a liquid crystal structure. Structurally, the liquid crystal structure is highly ordered, with alternating lipid bilayers and water layers forming a three-dimensional network. Regarding stability, the liquid crystal structure's viscoelasticity and high interfacial energy reduce oil droplet aggregation or component precipitation, preventing delamination or demulsification. Furthermore, the liquid crystal's lamellar structure can encapsulate active ingredients, isolating them from oxygen and photodegradation, slowing oxidation and preventing discoloration and precipitation. Therefore, creams with a liquid crystal structure exhibit improved stability. Efficacy-wise, the liquid crystal's lamellar structure resembles that of stratum corneum lipids (like dissolves like), disrupting the order of stratum corneum lipids and promoting transdermal penetration of active ingredients. The cubic liquid crystal phase forms "nanochannels," enabling sustained-release technology that effectively protects active ingredients and allows for their sustained release, slowing their diffusion rate and duration of action, thereby promoting their absorption and enhancing their efficacy. The strong water-binding capacity of the liquid crystal interlayers effectively enhances long-lasting moisturizing effects. Efficacy tests have shown that the liquid crystal cream of the present invention exhibits significantly greater moisturizing efficacy for 8 hours compared to conventional creams.

[0133] This comparative application example provides five moisturizing and soft facial creams, which differ from Application Example 1 only in that the soft emulsified composition provided in Example 1 is replaced with the soft emulsified compositions provided in Comparative Examples 1-5 in equal amounts. The remaining components and addition amounts are consistent with those in Application Example 1, and the preparation method refers to Application Example 1.

[0134] Test Example 1: Stability Evaluation

[0135] Test conditions: Samples from Application Examples 1-14 and Comparative Application Examples 1-5 were stored at -16°C, 25°C, and 45°C for 3 months, respectively. The appearance of the materials after 3 months under each condition was observed, and the results are recorded in Table 4 below.

[0136] Table 4

[0137]

[0138] As shown in Table 4, the cream prepared with the soft emulsified composition has good stability, while the cream without the soft emulsified composition is a stratified liquid that cannot form a soft and moisturizing cream.

[0139] It can be seen from Application Examples 4-5 that the ratio of cetearyl alcohol and hydrogenated coconut glycerides will affect the stability of the cream.

[0140] Comparative Application Examples 1-5 show that cetearyl glucoside and polysorbate 60 have a greater impact on stability, and cetearyl alcohol can also affect the properties of the product.

[0141] Test Example 2: Moisturizing Efficacy Test

[0142] (1) Test materials: samples of Application Examples 1-14 and Comparative Application Examples 1-5;

[0143] (2) Subjects: 133 volunteers with sensitive skin, aged 18 to 35 years old, were randomly divided into 19 groups, with 7 people in each group. Each group of volunteers tried the samples of Application Examples 1-14 and Comparative Application Examples 1-5 respectively;

[0144] (3) Test method: Volunteers washed their arms and dried them, and then stabilized them in a constant temperature and humidity laboratory for at least 30 minutes. A 2 cm × 2 cm area was drawn on each of the left and right forearms as the test area. The Corneometer CM825 skin moisture test probe was used to test the stratum corneum moisture content before use and 8 hours after use. The average of the three measurements was taken as the test value.

[0145] The results are shown in Table 5.

[0146] Table 5

[0147]

[0148] As shown in Table 5, the soft moisturizing cream prepared using the soft emulsion composition of the present invention can increase the moisture content of the skin even after 8 hours of use, showing an excellent moisturizing effect. The addition and selection of skin conditioners have a significant impact on the moisturizing effect.

[0149] Test Example 3: Crowd Trial Evaluation Test:

[0150] The subjects were the same group of volunteers as in Test Example 2, and each group of volunteers tried the samples of Application Examples 1-14 and Comparative Application Examples 1-5 respectively;

[0151] Test Method: After washing their faces and letting them dry naturally, volunteers applied an appropriate amount of the test substance to their hands and massaged their faces in circular motions for full absorption. This was repeated twice daily for 28 consecutive days. Follow-up questionnaires were conducted, with volunteers rating the experience based on softness, moisturizing, mildness, and soothing. A 5-point scale was used, with 5 indicating the best experience and 1 the worst. Any value between 1 and 5 could be selected. The average value was calculated, and the results are shown in Table 6.

[0152] Table 6

[0153]

[0154] As can be seen from Table 6, the facial cream prepared using the soft emulsion composition of the present invention has an excellent soft feel.

[0155] Comparative Application Examples 1-5 illustrate that the absence of any component in a soft emulsion composition will affect the softness and performance, especially in unstable formulations. Emollients have a certain impact on the softness and moisturizing feel of the cream.

[0156] In addition, skin conditioners have a greater impact on the performance of efficacy. Alpine Scutellaria flower / leaf / stem extract, algal oligosaccharides and hyaluronic acid have a greater impact on mildness and soothing degree, while algal oligosaccharides, glyceryl glucoside, camellia extract and hyaluronic acid have a greater impact on moisturizing effect.

[0157] Test Example 4: Safety Evaluation Experiment

[0158] The specific method is as follows: 40 women aged 18-35 years with no history of allergies were selected. Each subject was treated with the samples prepared in Examples 1-14. After cleaning the subject's back, a patch tester containing the sample was applied to the selected area on the back using non-irritating tape. After application, lightly press the patch with your finger to evenly adhere to the skin. This was continued for 48 hours. The subject was instructed to keep the patch area dry for 48 hours and avoid strenuous exercise, scratching, or prolonged sunlight exposure. After 48 hours, the patch tester was removed and marked. After 30 minutes, once the indentation had disappeared, the test was performed under adequate lighting.

[0159] The grading standards for adverse skin reactions are shown in Table 7:

[0160] Table 7

[0161]

[0162] The results are shown in Table 8:

[0163] Table 8

[0164]

[0165] The data in Table 8 show that after removing the spot tester, no adverse reactions were observed on the skin of the volunteers. This indicates that the raw materials used in the essence of the present invention are safe and non-irritating, have no adverse reactions to the human body, and are highly safe.
