Description

Technical Field

[0001] The invention belongs to the technical field of lipsticks, and in particular relates to a plant-derived lip balm and a preparation method thereof. Background Art

[0002] Lips are an extension of the human facial skin, but their stratum corneum is thinner than that of normal skin, and they do not have accessory organs such as sebaceous glands, hair follicles, and sweat glands. When the weather is cold or the air is dry, the lips usually peel, and in severe cases, they may crack and bleed.

[0003] As people's living standards gradually improve, people pay more and more attention to lip care. Lip balm has become one of the indispensable cosmetics in people's daily life. After use, it can make lips soft and shiny. Most of the lip balms currently sold on the market are mainly based on minerals and synthetic oils, such as vaseline, mineral oil, etc. Some products add colorants and flavors. Frequent use of lip balms containing chemical synthetic ingredients will irritate the lip mucosa and affect the oil secretion of the lips. Long-term use may induce chronic inflammation. In recent years, with the rise of pure beauty and cosmeceuticals, consumers' requirements for cosmetic ingredients are closer to nature.

[0004] Lip balms made from pure natural plant ingredients do not contain any colorants, flavors, or preservatives, minimizing the harm to human health caused by the raw materials of lip balms during use. However, existing plant lip balms not only have a single effect, but also need to be improved in terms of moisturizing, hydrating, and lightening lip lines. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a plant-derived lip balm and a preparation method thereof.

[0006] The first object of the present invention is to provide a plant-derived lip balm, wherein the raw materials of the plant-derived lip balm include, by weight:

[0007] Phase A: 0.5-1.5 parts of candelilla wax, 0.5-1.5 parts of carnauba wax, 7-9 parts of sunflower seed wax and 7-9 parts of rice bran wax;

[0008] Phase B: 30-40 parts of olive oil, 20-30 parts of sunflower seed oil, 1-3 parts of coconut oil, 1-3 parts of grape seed oil, 1-3 parts of camellia seed oil, 1-3 parts of avocado tree butter, 0.2-0.6 parts of jojoba seed oil and 0.2-0.6 parts of Melaleuca alternifolia leaf oil;

[0009] Phase C: 6-8 parts of polypeptide, 4-8 parts of emollient, 1-3 parts of antioxidant.

[0010] In one embodiment of the present invention, by candelilla wax, carnauba wax, sunflower seed wax and rice bran wax, compounding can be prepared soft and hard suitable lip balm, also have good emollient, and feel smooth and light, also reduce sticky feeling, thereby improve sensory effect. This is because candelilla wax, carnauba wax, sunflower seed wax and rice bran wax are all pure natural plant waxes, and their melting points are close, so not only the compatibility between these four kinds of wax is good, its superior oil binding ability makes these four kinds of waxes also have good compatibility with other components, thereby can improve the hardness and crystal structure of lip balm, improve its film forming property and lock water moisturizing ability. In addition, candelilla wax includes alkyl ester, free alcohol, hydrocarbon compound and free acid etc., is used in lipstick formula system, can improve product heat resistance stability, improve its product ductility, dispersibility, anti-shedding and other overall quality, simultaneously give lipstick bright gloss natural, lips feel very soft. The main components of Brazilian palm wax are palmitic acid beeswax and cerotic acid. Brazilian palm wax is thin and has low viscosity, low resin content, uniform coating, good flowability, good gloss, high finish, no greasy surface, and has a certain softening and lubricating effect. It also has good emulsification, adhesion, friction, release, slip and viscosity and hardness adjustment.

[0011] In one embodiment of the present invention, oleo-olive oil contains relatively high unsaturated fatty acids, vitamin E and other nutrients, which can improve the metabolism of the skin and improve the moisturizing performance. Squalane in oleo-olive oil is a natural moisturizing oil with a clear and transparent appearance, and has good antioxidant and thermal stability. Squalane is the main component of human sebum and hydrogen lipid layer, has natural affinity with the skin, can be integrated with the sebum membrane, form a natural barrier on the skin surface, and can inhibit the peroxidation of skin lipids, can effectively penetrate the skin, and promote the proliferation of skin basal cells, and has obvious physiological effects on delaying skin aging, improving and eliminating chloasma. Squalane can also open skin pores, promote blood circulation, enhance cell metabolism, and help repair damaged cells. Sunflower seed oil contains a large amount of linoleic acid and α-tocopherol, which has excellent effects of enhancing skin barrier function, improving skin immunity, and increasing skin permeability; it has the effect of lubricating the skin and fading lip lines, and has anti-inflammatory effects that promote the healing of skin wounds. Coconut oil has a unique coconut fragrance and is a vegetable saturated oil. Coconut oil contains a large amount of saturated fatty acid esters, free fatty acids, phytosterols, proteins, vitamin B1, vitamin C, etc. It is not easy to oxidize, can seal the skin, reduce water loss, and make the skin soft and smooth. In addition, it has a natural comprehensive antibacterial ability and can kill bacteria, fungi and viruses that cause diseases. Coconut oil is very similar to the lipid composition of the skin surface, so coconut oil can be quickly absorbed by the skin, minimize the loss of water in the epidermis, and play a moisturizing role. Coconut oil can also smooth and moisturize dry textures, increase the lipids on the surface of the skin, and deeply moisturize the skin. The main components of grape seed oil are linoleic acid and proanthocyanidins; linoleic acid helps the body absorb vitamin C and vitamin E, thereby promoting the antioxidant capacity of the body's cells, removing free radicals in the body, and delaying the aging of the body; proanthocyanidins can protect the lips from ultraviolet rays, prevent the destruction of collagen fibers and elastic fibers, and keep the lips elastic and tensile; in addition, grape seed oil contains minerals and proteins, which can enhance the moisturizing effect of the lips and relieve dry lips. The content of unsaturated fatty acids such as oleic acid and linoleic acid in camellia seed oil reaches 90%, which is the highest among natural plant oils. It also contains active ingredients such as vitamin E, squalene, sterols, camellia glycosides, tea polyphenols, etc., which can promote the synthesis of type I collagen and have anti-aging and anti-inflammatory effects. Avocado tree butter is rich in vitamin A, vitamin E, vitamin B6, protein and other elements. It is close to the various indicators of human sebum secretion. It contains rich non-saponifiable ingredients, which are easy for the human body to absorb, replenish the oil lacking in the human epidermal cells, have the effect of moisturizing and hydrating, and have the effect of delaying skin aging; in addition, avocado tree butter is also rich in unsaturated fatty acids, which can enhance the skin's moisturizing ability and moisturize dry skin with damaged keratin.After jojoba seed oil comes into contact with the skin, it will be quickly absorbed and penetrated, and soften the stratum corneum, making the skin soft and elastic; and jojoba seed oil has the advantages of not being easily oxidized and resistant to high temperatures, and has good touch and ductility in lip balm, can provide a soft and elastic skin feel, and is easily absorbed by the skin, and is rich in vitamins, calcium, magnesium and other substances, which can help improve the lips' absorption of external moisture. Melaleuca alternifolia leaf oil contains melaleuca, para-cymene, 4-terpineol, α-terpineol, 1,8-cineole, y-terpinene, carvacrol, ursolic acid and other ingredients, which have the effect of degrading the stratum corneum and enhancing the diffusion of other components on the skin, thereby promoting the penetration of other components. In this system, olive oil and jojoba seed oil can play a synergistic role, making the lip balm have significant moisturizing and repairing effects, and can be applied to lip products to improve their moisturizing and moisturizing properties, and reduce the irritation of lip products to the skin. In addition, this system can enhance the antioxidant capacity of catechins and other ingredients, further improve the anti-inflammatory effect of grape seed oil and other ingredients, and make the lip balm have an excellent repair effect on damage.

[0012] In one embodiment of the present invention, the polypeptide includes oligopeptide-1 and tripeptide-1. Oligopeptide-1 can not only promote the metabolism of the skin, thereby playing an anti-inflammatory role; it can also repair damaged skin cells, thereby playing a role in repairing the skin. In addition, oligopeptide-1 can also regulate cytokines in the skin, thereby regulating cytokines in the skin, improving the quality of the skin, thereby improving skin aging, etc. As a messenger peptide for collagen renewal, tripeptide-1 can stimulate fibroblasts to synthesize collagen and glycosaminoglycans, enhance the structural function of the dermis, regulate connective tissue reconstruction and cell proliferation, repair damaged stratum corneum, increase the stratum corneum barrier, improve skin resistance, and improve skin vitality.

[0013] In one embodiment of the present invention, the mass ratio of the oligopeptide-1 to the tripeptide-1 is (4-6):(1-3).

[0014] In one embodiment of the present invention, the emollient includes rice bran oil, sodium hyaluronate and di-diglycerol polyacyl adipate-2. Rice bran oil promotes the production of cholesterol and ceramide, which helps to improve the softness of the lips; activates glutathione reductase, promotes the repair of lip lines, and selects non-volatile plant oils, which can have a long-term moisturizing effect. Sodium hyaluronate can interact with water molecules, and its molecules are highly extended and entangled with each other to form a continuous mesh moisturizing film, while water molecules are combined with sodium hyaluronate molecules through polar bonds and hydrogen bonds in this network structure, so that sodium hyaluronate can absorb and retain a large amount of water; this protective film can form a good penetration environment on the skin surface, helping other active ingredients to better enter the deep layer of the skin; sodium hyaluronate can stimulate the synthesis of collagen, promote the regeneration and repair of skin cells, repair the skin, expand and fill the skin, and achieve the effect of solving lip lines and moisturizing. Bis-diglyceryl polyacyladipate-2 has high water-locking properties, excellent skin adhesion and smoothness, and can increase the gloss of the product. In addition, Bis-diglyceryl polyacyladipate-2 also has excellent emulsifying, dispersing, solubilizing and lubricating properties, and can be used as an emulsifier and thickener, significantly improving the compatibility of vegetable oils and making the lip balm easier to apply and absorb.

[0015] In one embodiment of the present invention, the mass ratio of the rice bran oil, sodium hyaluronate and bis-diglycerol polyacyl adipate-2 is (1-3):(2-4):(1-3).

[0016] In one embodiment of the present invention, the antioxidant includes catechin and tocopherol acetate. Catechins can reduce cell damage, and not only have good effects such as moisturizing lips, antibacterial and anti-inflammatory, but also have no side effects. Tocopherol acetate has antioxidant and anti-free radical effects, which can delay aging; it can also fade spots and lip lines, repair damaged lips, slow down the loss of moisture from the lip skin, and reduce the formation of lip lines. Long-term use can effectively enhance the elasticity of the lip skin, make the lips more plump, full, smooth, and firm, and improve the gloss of the lips. Adding a small amount of tocopherol acetate can synergistically improve the compatibility of active ingredients with catechins. Antioxidants such as catechins and tocopherol acetate are used in combination with natural raw materials such as olive oil, sunflower seed oil, coconut oil, grape seed oil, camellia seed oil, and emollients, which are more conducive to the lips absorbing active ingredients, making the lips more shiny and elastic, and achieving the repair of damaged lips.

[0017] In one embodiment of the present invention, the mass ratio of catechin to tocopherol acetate is (2-4):(1-3).

[0018] The second object of the present invention is to provide a method for preparing the plant-derived lip balm, comprising the following steps:

[0019] S1, stirring and heating candelilla wax, carnauba wax, sunflower seed wax and rice bran wax to obtain material A;

[0020] S2, cooling the material A described in S1, adding olive oil, sunflower seed oil, coconut oil, grape seed oil, camellia seed oil, avocado tree fat, jojoba seed oil and Melaleuca alternifolia leaf oil and stirring evenly to obtain material B;

[0021] S3, cooling the material B described in S2, adding an emollient and an antioxidant and stirring evenly, and obtaining the plant-derived lip balm through filling and demoulding.

[0022] In one embodiment of the present invention, in S1, the stirring and heating temperature is 90°C-95°C, and the speed is 1400rpm-1600rpm.

[0023] In one embodiment of the present invention, in S2, the temperature of material A after cooling is 80°C-85°C;

[0024] In S3, the temperature of material B after cooling is 60°C-65°C.

[0025] The technical solution of the present invention has the following advantages over the prior art:

[0026] The plant-derived lip balm of the present invention not only has excellent moisturizing, antioxidant and anti-inflammatory properties, but also has a certain preventive and therapeutic effect on cheilitis, and effectively protects the lips. DETAILED DESCRIPTION
