Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, and in particular relates to a squalane lip essence oil and its preparation process. Background Technology

[0002] Lip skin differs significantly from skin on other parts of the body. The stratum corneum of the lips is very thin, making it extremely sensitive and prone to dryness, cracking, and peeling, which can lead to cheilitis in severe cases. Compared to facial skincare products, lip care products have extremely high requirements for safety and gentleness. Existing gentle lip care products are not effective at moisturizing and locking in moisture, and cannot repair damaged lip skin. Natural squalane is mainly derived from plants and deep-sea shark livers. Shark-derived squalane, due to increasingly severe marine environmental pollution, wide range of activity, and diverse food sources, as the apex predator in the marine food chain, accumulates relatively large amounts of heavy metals and various toxins, making it less safe than plant-derived squalane. Summary of the Invention

[0003] To address the aforementioned technical problems, the objective of this invention is to propose a squalane lip essence oil and its preparation process.

[0004] The technical solution of this invention is implemented as follows:

[0005] A squalane lip serum oil comprising the following ingredients:

[0006] Phase A

[0007] SOLE F1306S (tetranol trimellitate) 35%-50%;

[0008] COSMOL 222 (diisostearyl malate) 5%-15%;

[0009] 2EHP (ethylhexyl palmitate) 1%-3%;

[0010] 972 hydrogen powder (dimethylsilylated silica) 0.5%-1.5%;

[0011] Phase B

[0012] NOMCORT HK-G (glyceryl behenate / eicosanoate) 0.5%-1.5%;

[0013] PB2400 (polyisobutylene) 13%-17%;

[0014] C phase

[0015] Ellamera BI-THIN™ 602 (Hydrogenated (styrene / isoprene) copolymer / pentaerythritol tetra(bis-tert-butylhydroxyhydrogenated cinnamic acid) ester) 13%-17%;

[0016] Plant-derived squalane 18%-24%;

[0017] Camellia seed oil 2%-3%;

[0018] Shea butter 1%-3%;

[0019] Avocado oil 0.05%-0.2%;

[0020] Baobab oil: 0.1%-0.3%;

[0021] Comfrey oil 0.1%-1%;

[0022] Vitamin E acetate 0.1%-0.3%;

[0023] Phase D

[0024] Pigment paste (G68-2235 / G75255 / G459860) 0.05%-0.2%.

[0025] A preparation process for a squalane lip serum oil includes the following steps:

[0026] Step 1: Mix the phase A oils together and stir evenly. Then add 972 hydrogen powder while stirring and quickly disperse (at or above 1800 rpm) until uniform and free of particles.

[0027] Step 2: First, mix and stir the Ellamera BI-THIN™ 602 and plant squalane in the C phase (100 rpm) until uniform. Then, heat and keep warm in an 80°C water bath for more than 24 hours until the soaking is transparent and free of particles. Then, take it out, stir it evenly, cool it down to below 45°C, and then add the other raw materials of the C phase all at once and stir evenly.

[0028] Step 3: Add phase B to the prepared phase A, stir and heat to 85°C, stir thoroughly (100 rpm) until completely dissolved and free of particles, then pour the prepared phase C into phases A and B, stir thoroughly and quickly (above 1800 rpm) until uniform, cool to below 65°C, add the prepared phase D color paste and stir evenly, cool to below 45°C and discharge.

[0029] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0030] This invention creates a squalane lip essence oil through a formulation of ingredients. This formula, by adding plant-based squalane and synergistically combining it with comfrey root extract and plant oils, can significantly moisturize and nourish the lips, and also has a repairing effect on damaged, chapped, and inflamed lip skin. By combining squalane with other oils, it not only retains the glossy appearance of traditional lip glosses, but more importantly, it exerts repairing, moisturizing, anti-inflammatory, and soothing effects when in contact with the lip skin.

[0058] Step 1: Mix the phase A oils together and stir evenly. Then add 972 hydrogen powder while stirring and quickly disperse (at or above 1800 rpm) until uniform and free of particles.

[0059] Step 2: First, mix and stir the Ellamera BI-THIN™ 602 and plant squalane in the C phase (100 rpm) until uniform. Then, heat and keep warm in an 80°C water bath for more than 24 hours until the soaking is transparent and free of particles.

[0061] The core of the development of squalane lip serum oil lies in utilizing the excellent affinity and stability of squalane, while combining it with other active ingredients to achieve deep moisturizing, repair and barrier strengthening in the special area of ​​the lips.

[0062] The following analysis will focus on the characteristics of raw materials, formulation technology, and preparation process.

[0063] The properties and functions of squalane, a core ingredient:

[0064] like Figure 1 As shown, squalane is the key functional base of this type of product, and its physicochemical properties determine the product's feel and basic efficacy.

[0065] Origin and Structure: Originally derived from the hydrogenation of squalene in deep-sea shark liver oil, it is now also commonly synthesized from plant-based raw materials such as olive oil. It is a chemically very stable hydrocarbon oil.

[0066] Squalane is absorbed by the skin 5-10 times more readily than other oils; compared to other oils, squalane can transport active ingredients more effectively.

[0067] Natural squalane primarily originates from plants and the livers of deep-sea sharks. Shark sources are particularly problematic due to increasingly severe marine pollution. Sharks, being apex predators in the marine food chain, accumulate relatively large amounts of heavy metals and other toxins, making them less safe than those from plant sources. Plant sources, mainly annual grasses such as rice bran and soybeans, and perennial woody plants such as olives and camellias, offer more controllable growing environments, resulting in shorter toxin accumulation periods and higher safety. More specifically, annual grass sources are generally safer than perennial woody sources.

[0068] The squalane used in this invention is derived from plants, and its core skincare properties are:

[0069] Excellent affinity: Squalane is one of the lipids with a structure most similar to human sebum, and it can quickly integrate with the sebum film of the lip skin to form a natural protective barrier.

[0070] Penetration and Spreadability: It has moderate spreadability, is pure, colorless, and odorless, and feels thick and moisturizing without being greasy. More importantly, it promotes the penetration of other active ingredients in the formula into the skin.

[0071] Repair and promote regeneration: Studies have shown that squalane can inhibit lipid peroxidation in the skin, promote the proliferation of basal cells in the skin, accelerate the repair of damaged cells, and has a repairing effect on dry and damaged lips.

[0072] Formulation technology and synergistic effects

[0073] While squalane alone is moisturizing, modern lip oils typically employ compounding techniques to achieve more comprehensive moisturizing and repairing effects.

[0074] The squalane used in this research and development is plant-derived squalane. By combining it with other core active ingredients and optimizing different formulas, we have obtained a squalane lip serum oil with excellent final results.

[0075] Highly effective compositions typically contain the following synergistic components:

[0076] Core compound system:

[0077] Phytosterols / Ocyldodecyl lauroyl glutamate: This is an amino acid derivative that acts as a mild emulsifying stabilizer and emollient, enhancing the luxurious feel and moisturizing power of the formula.

[0078] Comfrey root extract: As a natural plant extract, it provides anti-inflammatory and soothing effects, targeting inflammation and chapped lips that are prone to occur.

[0079] Vegetable oils: As a complementary source of oils, they complement squalane, providing different fatty acids and a moisturizing feel.

[0080] Synergistic Effect: The above ingredients, when combined with squalane, do not simply add up, but rather achieve a synergistic effect. The composition not only significantly moisturizes and hydrates, but also has a good repairing effect on damaged, dry, and inflamed lip skin.

[0081] The specific implementation examples are as follows:

[0082] Example 1

[0083] SOLE F1306S (tridecyl trimellitate) 46.9%;

[0084] COSMOL 222 (diisostearyl malate) 7.0%;

[0085] 2EHP (ethylhexyl palmitate) 2.0%;

[0086] 972 hydrogen powder (dimethylsilylated silica) 1.0%;

[0087] Phase B

[0088] NOMCORT HK-G (glyceryl behenate / eicosanoate) 1.0%;

[0089] PB2400 (polyisobutylene) 15.0%;

[0090] C phase

[0091] Ellamera BI-THIN™ 602 (Hydrogenated (styrene / isoprene) copolymer / pentaerythritol tetra(bis-tert-butylhydroxyhydrogenated cinnamic acid) ester) 1.5%;

[0092] Plant-derived squalane 20.0%;

[0093] Camellia seed oil 2.5%;

[0094] Shea butter 2.0%;

[0095] Avocado oil 0.1%;

[0096] Baobab oil 0.2%;

[0097] Comfrey oil 0.5%;

[0098] Vitamin E acetate 0.2%;

[0099] Phase D

[0100] Pigment paste (G68-2235 / G75255 / G459860) 0.1%.

[0101] The preparation process of the squalane lip serum oil in Example 1 includes the following steps:

[0102] Step 1: Mix the phase A oils together and stir evenly. Then add 972 hydrogen powder while stirring and quickly disperse (at or above 1800 rpm) until uniform and free of particles.

[0103] Step 2: First, mix and stir the Ellamera BI-THIN™ 602 and plant squalane in the C phase (100 rpm) until uniform, then grind them three times using a three-roll mill. Then, add the other raw materials of the C phase at once and stir until uniform.

[0104] Step 3: Add phase B to the prepared phase A, stir and heat to 85°C, stir thoroughly (100 rpm) until completely dissolved and free of particles, then pour the prepared phase C into phases A and B, stir thoroughly and quickly (above 1800 rpm) until uniform, cool to below 65°C, add the prepared phase D color paste and stir evenly; cool to below 45°C and discharge.

[0105] The material obtained in Example 1 above showed poor transparency, poor gloss, and insufficient moisturizing properties. It did not fully achieve the desired moisturizing, repairing, soothing, and anti-inflammatory effects. Overall analysis revealed two main problems: first, the use of oils with high refractive index was insufficient, requiring further adjustments to the formulation and process; second, during the dispersion and grinding of Ellamera BI-THIN™ 602, the plant squalane was not allowed enough time to disperse, resulting in insufficient swelling and remaining as fine particles within the plant squalane. Consequently, the final product did not form a continuous and uniform interfacial film on the skin.

[0106] like Figure 2 As shown, under a polarizing microscope, the white fine particles are Ellamera BI-THIN™ 602. Some squalane exists in the fine particles with a relatively large specific surface area, which also leads to a low content of squalane and incomplete release. Therefore, Example 2 was carried out.

[0107] Example 2

[0108] Phase A

[0109] SOLE F1306S (tetranol trimellitate) 40.1%;

[0110] COSMOL 222 (diisostearyl malate) 12.0%;

[0111] 2EHP (ethylhexyl palmitate) 2.0%;

[0112] 972 hydrogen powder (dimethylsilylated silica) 1.0%;

[0113] Phase B

[0114] NOMCORT HK-G (glyceryl behenate / eicosanoate) 1.0%;

[0115] PB2400 (polyisobutylene) 15.0%;

[0116] C phase

[0117] Ellamera BI-THIN™ 602 (Hydrogenated (styrene / isoprene) copolymer / pentaerythritol tetra(bis-tert-butylhydroxyhydrogenated cinnamic acid) ester) 1.5%;

[0118] Plant-derived squalane 22.0%;

[0119] Camellia seed oil 2.5%;

[0120] Shea butter 2.0%;

[0121] Avocado oil 0.1%;

[0122] Baobab oil 0.2%;

[0123] Comfrey oil 0.3%;

[0124] Vitamin E acetate 0.2%;

[0125] Phase D

[0126] Pigment paste (G68-2235 / G75255 / G459860) 0.1%.

[0127] The preparation process of the squalane lip serum oil in Example 2 includes the following steps:

[0128] Step 1: Mix the phase A oils together and stir evenly. Then add 972 hydrogen powder while stirring and quickly disperse (at or above 1800 rpm) until uniform and free of particles.

[0129] Step 2: First, mix and stir the Ellamera BI-THIN™ 602 and plant squalane in the C phase (100 rpm) until uniform. Then, heat and keep warm in an 80°C water bath for more than 24 hours until the soaking is transparent and free of particles. Then, take it out and stir it evenly. Then, add the other raw materials of the C phase at one time and stir evenly.

[0130] Step 3: Add phase B to the prepared phase A, stir and heat to 85°C, stir thoroughly (100 rpm) until completely dissolved and free of particles, then pour the prepared phase C into phases A and B, stir thoroughly and quickly (above 1800 rpm) until uniform, cool to below 65°C, add the prepared phase D color paste and stir evenly; cool to below 45°C and discharge.

[0131] The material obtained in Example 2 showed significantly improved transparency and excellent gloss. Example 2 reduced the amounts of SOLE F1306S (tridecyl trimellitate) and comfrey oil, increased the amounts of COSMOL 222 (diisostearyl malate) and plant squalane, and improved the preparation process by using a water bath process, such as... Figure 3 As shown, under a polarizing microscope, no fine white particles of Ellamera BI-THIN™ 602 were observed. No fine particles were observed under the polarizing microscope, and the moisturizing effect was sufficient. After use, it fully achieved the effects of moisturizing, repairing, soothing and anti-inflammatory. However, the viscosity of the material is relatively high, and the spreadability is slightly poor. Therefore, Example 3 was implemented.

[0132] Example 3

[0133] Phase A

[0134] SOLE F1306S (tridecyl trimellitate) 40.6%;

[0135] COSMOL 222 (diisostearyl malate) 12.0%;

[0136] 2EHP (ethylhexyl palmitate) 2.0%;

[0137] 972 hydrogen powder (dimethylsilylated silica) 0.8%;

[0138] Phase B

[0139] NOMCORT HK-G (glyceryl behenate / eicosanoate) 1.0%;

[0140] PB2400 (polyisobutylene) 15.0%;

[0141] C phase

[0142] Ellamera BI-THIN™ 602 (Hydrogenated (styrene / isoprene) copolymer / pentaerythritol tetra(bis-tert-butylhydroxyhydrogenated cinnamic acid) ester) 1.2%;

[0143] Plant-derived squalane 22.0%;

[0144] Camellia seed oil 2.5%;

[0145] Shea butter 2.0%;

[0146] Avocado oil 0.1%;

[0147] Baobab oil 0.2%;

[0148] Comfrey oil 0.3%;

[0149] Vitamin E acetate 0.2%;

[0150] Phase D

[0151] Pigment paste (G68-2235 / G75255 / G459860) 0.1%.

[0152] The preparation process of the squalane lip serum oil in Example 3 includes the following steps:

[0153] Step 1: Mix the phase A oils together and stir evenly. Then add 972 hydrogen powder while stirring and quickly disperse (at or above 1800 rpm) until uniform and free of particles.

[0154] Step 2: First, mix and stir the Ellamera BI-THIN™ 602 and plant squalane in the C phase (100 rpm) until uniform. Then, heat and keep warm in an 80°C water bath for more than 24 hours until the soaking is transparent and free of particles. Then, take it out, stir it evenly, cool it down to below 45°C, and then add the other raw materials of the C phase all at once and stir evenly.

[0155] Step 3: Add phase B to the prepared phase A, stir and heat to 85°C, stir thoroughly (100 rpm) until completely dissolved and free of particles, then pour the prepared phase C into phases A and B, stir thoroughly and quickly (above 1800 rpm) until uniform, cool to below 65°C, add the prepared phase D color paste and stir evenly; cool to below 45°C and discharge.

[0156] The material obtained through the above-described embodiment 3, while maintaining the advantages of embodiment 2, had its formulation ratio appropriately adjusted. The amount of SOLE F1306S (tridecyl trimellitate) was increased, while the amounts of 972 hydrogen powder and Ellamera BI-THIN™ 602 were reduced. The preparation process was also improved by adding other raw materials in the C phase at a temperature below 45°C to ensure that the efficacy of other plant oils (extracts) was not reduced due to heat sensitivity. The slight change in the formulation ratio reduced the viscosity of the material, giving it a certain degree of fluidity and making it easy to apply. Ultimately, embodiment 3 was determined to be the best.

[0157] The results of the test on the material in Example 3 after 28 days showed that CREAM A, a squalane lip essence oil, could significantly improve skin elasticity after 28 days.

[0158] As shown in the table below, the material in Example 3 passed the 12-week stability test and showed no abnormalities.

[0159]

[0160] Through the above research and development, Ellamera BI-THIN™ 602 was dispersed in plant squalane. It was verified that the water bath temperature must be controlled at 80°C and the soaking time must be more than 24 hours to ensure better dispersion of Ellamera BI-THIN™ 602 and optimal transparency of the material.

[0161] This invention addresses the deficiencies in the prior art and offers the following beneficial effects: This invention provides a squalane lip essence oil and its preparation process. This formula, by adding plant-based squalane and synergistically enhancing it with comfrey root extract and plant oils, can significantly moisturize and nourish the lips. It also has a repairing effect on damaged, dry, and inflamed lip skin. Through the combination of squalane and other oils, it not only retains the glossy appearance of traditional lip glosses but, more importantly, exerts repairing, moisturizing, anti-inflammatory, and soothing effects when in contact with the lip skin.

[0162] 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.
