Description

Technical Field

[0001] This invention relates to the field of lipstick preparation technology, and in particular to an edible lipstick rich in grape seed oil and its preparation method. Background Technology

[0002] Cosmetics have become necessities in everyone's life. More and more consumers prefer to use products that are natural, safe, and have makeup effects. Lipstick is currently the most widely used lip makeup product. Some lipsticks in the mall generally use mineral oil, synthetic wax, artificial pigments, and chemical preservatives as core ingredients. Although they can achieve basic coloring and makeup-holding effects, they have significant drawbacks: they contain artificial pigments, which can cause skin allergies, dry lips, peeling, and deepened lip lines with long-term use. They may also cause redness and swelling of the lips. The threat to human health should not be underestimated. Therefore, for women, lipstick is not only a fashion issue, but its safety is also an urgent matter.

[0003] Currently available edible lipstick technologies mostly use conventional edible oils such as olive oil, coconut oil, and shea butter as a base. While this improves product safety, it still presents unresolved technical challenges. These challenges primarily manifest in the following ways: limited functionality – conventional edible oils only provide basic moisturizing and lack active lip care benefits such as antioxidant and anti-photoaging properties, failing to meet consumers' demand for a combined makeup and skincare experience; poor makeup performance – natural pigments have poor stability, leading to easy fading and transfer, failing to achieve the staying power of traditional synthetic lipsticks; and an imbalance between skin feel and taste – adding excessive wax to improve staying power results in a hardened lipstick that settles into lines, while a high oil ratio leads to a soft, easily melted lipstick. Additionally, some ingredients have unpleasant odors, affecting the user experience. Grape seed oil, rich in proanthocyanidins and unsaturated fatty acids (linoleic acid), possesses excellent antioxidant, skin barrier repair, and free radical scavenging effects. If it can be properly compounded and applied to edible lipsticks, it can effectively solve the core pain points of insufficient functionality and the difficulty in balancing safety and makeup performance in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide an edible lipstick rich in grape seed oil and its preparation method. All raw materials (grape seed oil, sweet almond oil, shea butter, candelilla wax, beeswax, capsanthin, and vitamin E) are food-grade, free of harmful additives such as mineral oil, synthetic pigments, and chemical preservatives, making it safe for accidental ingestion and suitable for all groups, including pregnant women and children. This fundamentally solves the safety hazards of traditional lipsticks. With grape seed oil as the core functional ingredient, its rich proanthocyanidins and unsaturated fatty acids effectively eliminate free radicals, repair lips, and improve lip lines. Combined with the deep-penetrating moisturizing of sweet almond oil, the soothing and repairing properties of shea butter, and the synergistic antioxidant effects of vitamin E, it achieves both makeup and daily care. Long-term use can improve lip health, solving the problem of traditional lipsticks that only provide makeup without nourishment and have limited functionality.

[0005] By optimizing the proportions of raw materials (7-9 mL grapeseed oil, 4-6 mL sweet almond oil, 1.3-1.7 g shea butter, 0.8-1.2 g candelilla wax, and 1.8-2.2 g beeswax), a scientific balance of oils and waxes is achieved. This ensures both the hardness and formability of the lipstick, preventing melting at high temperatures and oil separation at low temperatures, while also guaranteeing smooth application without drying out the lips or causing creasing. Furthermore, the use of natural capsanthin as a colorant results in even and rich coloring with strong staying power, addressing the industry pain points of natural pigment lipsticks being prone to fading and having poor makeup effects.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: This invention provides an edible lipstick rich in grape seed oil, which is prepared from raw materials comprising the following proportions: 7-9 mL grape seed oil, 4-6 mL sweet almond oil, 1.3-1.7 g shea butter, 0.8-1.2 g candelilla wax, 1.8-2.2 g beeswax, 0.8-1.2 g capsanthin, and 80-120 μL vitamin E.

[0007] Preferably, the edible lipstick is prepared from raw materials comprising the following proportions: 8 mL grape seed oil, 5 mL sweet almond oil, 1.5 g shea butter, 1 g candelilla wax, 2 g beeswax, 1 g capsanthin, and 100 μL vitamin E.

[0008] Preferably, the grape seed oil, sweet almond oil, shea butter, candelilla wax, beeswax, capsanthin, and vitamin E are all food-grade raw materials.

[0009] The present invention also provides a method for preparing the edible lipstick, comprising the following steps: (1) Weigh out grape seed oil, sweet almond oil, shea butter, candelilla wax, beeswax, capsanthin and vitamin E in proportion and set aside; (2) Mix grape seed oil, sweet almond oil, shea butter, candelilla wax and white beeswax, heat to dissolve, then add capsanthin and vitamin E. After the capsanthin is completely dissolved, the mixture is obtained. (3) After cooling the mixture, the edible lipstick is obtained.

[0010] Preferably, the heating in step (2) is performed using a water bath, and the temperature of the water bath is 75~85℃.

[0011] Preferably, the cooling temperature in step (3) is -16 to -20°C, and the cooling time is 15 to 25 minutes.

[0012] This invention provides an edible lipstick rich in grape seed oil and its preparation method. The edible lipstick is prepared from raw materials comprising the following proportions: 7-9 mL grape seed oil, 4-6 mL sweet almond oil, 1.3-1.7 g shea butter, 0.8-1.2 g candelilla wax, 1.8-2.2 g beeswax, 0.8-1.2 g capsanthin, and 100 μL vitamin E. The edible lipstick rich in grape seed oil prepared by this invention exhibits outstanding aroma and moisturizing properties, fully meeting the edible positioning of "light fruity flavor" and "non-greasy." Furthermore, its overall score is higher than commercially available lipsticks, indicating that the edible lipstick rich in grape seed oil prepared by this method demonstrates the competitiveness of a natural food-grade formula in terms of sensory experience, making it particularly suitable for those seeking safety and moisturizing benefits.
