Description

Technical Field

[0001] The invention relates to the technical field of lip balms, and in particular to a moisturizing and repairing lip balm that is easy to spread and disperse, and a preparation method thereof. Background Art

[0002] In autumn and winter, lips often feel dry, and in severe cases, they may even become chapped. Lip balm can moisturize and care for the lip skin, helping to prevent dryness and chapped lips.

[0003] Currently, lip balms are typically made with natural waxes and plant oils as a base material, with other functional ingredients such as moisturizers and antioxidants added as needed. Traditional lip balms can become sticky and fall off in extreme environments, requiring frequent reapplication of medicated creams. However, most products suffer from poor color rendering or leave a white film, resulting in a layered appearance that hinders use in social settings and reduces moisturizing effectiveness. Therefore, a moisturizing and repairing lip balm that is easy to apply and disperse, and a method for its preparation, were proposed. Summary of the Invention

[0004] In view of this, the embodiments of the present invention provide a moisturizing and repairing lip balm that is easy to spread and disperse, and a preparation method thereof, so as to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0005] The technical solution of the embodiment of the present invention is achieved as follows: a moisturizing and repairing lip balm that is easy to spread and disperse, composed of the following ingredients: 1 part of beeswax, 3.5 parts of yak butter, 0.5 part of sea buckthorn fruit oil, 0.3 part of sweet almond oil, 0.3 part of vitamin E oil and 0.3 part of plateau local honey.

[0006] A method for preparing a moisturizing and repairing lip balm that is easy to spread and disperse, comprising the following steps: S1. Place beeswax, yak butter, and sea buckthorn fruit oil in a beaker, heat the beaker in water at 68±2°C, and stir until completely melted or transparent, thereby obtaining an oil phase mixture. S2. When the oil phase mixture is cooled to 53±2°C, sweet almond oil, vitamin E oil, and pre-emulsified honey are added and stirred for ≤30 seconds to obtain a lipstick emulsion; S3, after cooling the lipstick emulsion to 48-50°C, slowly pour the lipstick emulsion into the lipstick tube through a syringe; S4. Refrigerate the lipstick tube in S3 in a 4°C refrigerator for 0.3 h, then take it out and warm it up to increase the crystal density of the lipstick emulsion by 20% and the unscrewing resistance ≤ 0.5 N·m.

[0007] In some embodiments, in S1, the yak butter needs to be heated at 40° C., filtered to remove milk residue, and then vacuum degassed and pasteurized to eliminate the fishy smell.

[0008] In some embodiments, in S1, the beeswax needs to be chopped into particles ≤ 5 mm to accelerate melting.

[0009] In some embodiments, the pre-emulsified honey in S2 is mixed with honey and yak butter to prevent stratification, and the ratio of honey to yak butter is 1:10.

[0010] In some embodiments, in S3, the flow rate of the needle perfusion is 1 ml / s.

[0011] In some embodiments, in S3, the lipstick tube is pre-cooled to -10°C to prevent bubbles from being generated when the lipstick emulsion is poured.

[0012] The embodiment of the present invention adopts the above technical solution, which has the following advantages: The present invention uses refined yak butter to repair the lip barrier, sea buckthorn fruit oil and vitamin E oil to carry out antioxidant and low-temperature phase separation emulsification processes, thereby overcoming the pain points of traditional lipsticks such as stickiness and easy stratification, improving the effect of easy application and dispersion, and having protection for use in plateaus, thereby improving the effect of moisturizing and repairing the lips.

Therefore, limitations on features such as "first" and "symmetrical" may explicitly or implicitly include one or more of these features; similarly, when the quantity of certain features is not limited in the form of words such as "two" or "three," it should be noted that these features also explicitly or implicitly include one or more of the number of features.

[0016] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", and "fixation" should be understood in a broad sense; for example, it can be a fixed connection, a detachable connection, or an integral molding; it can be a mechanical connection, a direct connection, welding, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0017] The embodiment of the present invention provides a moisturizing and repairing lip balm that is easy to spread and disperse, and is composed of the following ingredients: 1 part of beeswax, 3.5 parts of yak butter, 0.5 part of sea buckthorn fruit oil, 0.3 part of sweet almond oil, 0.3 part of vitamin E oil, and 0.3 part of plateau local honey.

[0018] A method for preparing a moisturizing and repairing lip balm that is easy to spread and disperse, comprising the following steps: S1. Place beeswax, yak butter, and sea buckthorn fruit oil in a beaker, heat the beaker in water at 68±2°C, and stir until completely melted or transparent, thereby obtaining an oil phase mixture. S2. When the oil phase mixture is cooled to 53±2°C, sweet almond oil, vitamin E oil, and pre-emulsified honey are added and stirred for ≤30 seconds to obtain a lipstick emulsion; S3, after cooling the lipstick emulsion to 48-50°C, slowly pour the lipstick emulsion into the lipstick tube through a syringe; S4. Refrigerate the lipstick tube in S3 in a 4°C refrigerator for 0.3 h, then take it out and warm it up to increase the crystal density of the lipstick emulsion by 20% and the unscrewing resistance ≤ 0.5 N·m.

[0019] In this embodiment, specifically, in S1, the yak butter needs to be heated at 40° C., filtered to remove milk residue, and then vacuum degassed and pasteurized to eliminate the fishy smell.

[0020] In this embodiment, specifically, in S1, the beeswax needs to be chopped into particles ≤ 5 mm to accelerate melting.

[0021] In this embodiment, specifically, the pre-emulsified honey in S2 is mixed with honey and yak butter to prevent stratification, and the ratio of honey to yak butter is 1:10.

[0022] In this embodiment, specifically, in S3, the flow rate of the needle perfusion is 1 ml / s.

[0023] In this embodiment, specifically, in S3 , the lipstick tube is pre-cooled to -10° C. to prevent bubbles from being generated when the lipstick emulsion is poured.

[0024] In this embodiment, specifically, Sea buckthorn fruit oil replaces 20% of yak butter, eliminating the greasy feeling while improving antioxidant properties (DPPH clearance rate ↑25%).

[0025] In this embodiment, specifically, 1. Smear dispersion test 1. Test methods and objects • Equipment: rotational viscometer (to measure paste viscosity), electronic tensile testing machine (ETT-A model, to measure breaking force) and foam ball adhesion device (to simulate sticky feeling); • Test sample: This formula lipstick vs. commercially available Vaseline-based lipstick; • Volunteers: 30 adults (18-45 years old, half male and half female), with no history of lip damage, divided into Group A (this formula) and Group B (control group vaseline lipstick); 2. Test Data Mechanism of action: The low viscosity and high ductility are due to the small molecule permeability of sweet almond oil (friction coefficient reduced by 40%) and the optimized beeswax-to-ghee ratio (1:3.5), which allows the paste to liquefy quickly at body temperature.

[0026] Note: The breaking force test is carried out in accordance with GB / T 26513 at a rate of 10 mm / min.

[0027] 2. Moisturizing Test 1. Test methods and objects • Equipment: Corneometer® CM825 (stratum corneum water content) and Tewameter® TM300 (transepidermal water loss, TEWL); • Environment: temperature 22°C, humidity 30% (simulated dry environment); • Volunteers: 30 people with dry lips (lip moisture content ≤15%), use 4 times a day for 7 days; 2. Moisturizing time comparison Key Stats: • Instant hydration: Water content ↑166.9% in 1 hour (Vaseline version ↑100.7%) • Long-lasting moisture lock: retains 30.1% moisture after 8 hours (Vaseline version drops to 18.3%) • TEWL inhibition: 41% reduction in transepidermal water loss in 4 hours.

[0028] Honey + sea buckthorn oil form a dual pathway of "moisture absorption and moisture lock": honey's low-molecular sugar captures moisture, sea buckthorn's vitamin C (12 times the content of orange) maintains barrier integrity through antioxidant properties; yak butter simulates sebum structure and repairs the lip stratum corneum.

[0029] 3. Repairability Test (Clinical Verification) 1. Test methods and objects • Equipment: Confocal microscope (to observe the integrity of the stratum corneum); Clinical cracking score (0-4, 0 = no cracking); • Volunteers: 20 patients with severe cleft lip (cleft depth ≥ 2 levels), thick compress + plastic wrap closure at night; 2. Repair effect data Histological comparison: • Before use: stratum corneum damage rate 45%, collagen density 12.3μg / mm².

[0030] • After 7 days of use: the breakage rate dropped to 8% and the collagen density increased to 28.6μg / mm² (↑132.5%).

[0031] Extreme environment verification: • -10℃ protection: The incidence of cleft lip decreased by 70% among 10 plateau workers after using it (the control group decreased by 30%).

[0032] It has the following advantages: 1. Spreadability: Sweet almond oil reduces viscosity to 3150 mPa·s, increases spreadability by 115%, and has a foam ball adhesion count of only 12, demonstrating its light and non-sticky texture. 2. Moisturizing: The combination of sea buckthorn oil and honey maintains lip moisture content at 30.1% for 8 hours, reduces TEWL by 41%, and locks in moisture longer than Vaseline (18.3%). 3. Repair ability: Yak ghee promotes collagen regeneration + vitamin E anti-oxidation, the chapped skin repair rate is 92% in 7 days, and the protective effect in plateau environment is increased by 70%.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications and substitutions within the technical scope disclosed in the present invention, and such modifications and substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
