Technical Field

[0001] The present invention relates to the technical field of cosmetics, and specifically relates to a plant essential oil composition with skin repair function and its application. Background Art

[0002] The skin is the largest organ of the human body, playing a role in protecting various tissues and organs in the body from physical, chemical, and pathogenic microorganism attacks. With the progress of chemistry and biology, scientists have begun to develop more complex formulations and ingredients. In the 20th century, the skincare industry has experienced huge innovations, including the introduction of synthetic chemical components, breakthroughs in dermatology, and research on anti-aging technologies. In recent years, the rise of natural and organic ingredients, personalized skincare, and technological advancements (such as high-efficiency ingredient release systems) have further promoted the development of skincare products.

[0003] When choosing inappropriate cosmetics, the skin will be irritated, and the skin barrier will be damaged, further triggering an inflammatory response. According to statistics, the proportion of people with sensitive skin globally has exceeded 60% (Expert Consensus on the Diagnosis and Treatment of Sensitive Skin in China 2023). Chinese Patent with publication number CN119280085A discloses a natural skin repair composition, which uses a variety of plant extracts as the main ingredients and can effectively repair the irritating problems of the skin, but it cannot effectively repair skin aging and oxidation; Chinese Patent with publication number CN117137830A discloses a skin repair composition and its application, which uses a combination of various chemical components and short peptides to effectively repair skin aging and oxidation problems, but its skin repair function is limited, and long-term use will cause dependence and cannot effectively solve other skin problems; consumers' demand for multi-functional products with barrier repair, anti-inflammatory, antioxidant, and anti-aging functions has increased sharply.

[0004] In view of the above problems, the present invention provides a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide a plant essential oil composition with skin repair function and its application, which can provide long-lasting moisturization, oil control, and repair of the skin barrier.

[0006] To achieve the above purpose, the present invention adopts the following technical scheme: A plant essential oil composition with skin repair function is composed of the following percentage components: 35 - 50% coconut oil, 15 - 20% Limnanthes alba seed oil, 5 - 10% sandalwood oil, 5 - 10% Cupressus sempervirens oil, 1 - 2% Salvia sclarea oil, 1 - 3% Ocimum basilicum oil, 2 - 5% Ligusticum wallichii oil, 1 - 2% azulene, 0.5 - 1% Portulaca oleracea extract, and 0.5 - 1% rosemary essential oil;

[0007] The preparation method of rosemary essential oil includes the following steps:

[0008] A1: Select freshly picked fresh rosemary branches and leaves, add them to deionized water for cleaning. After cleaning, remove the damaged rosemary branches and leaves. Put the cleaned rosemary branches and leaves into an ultrasonic cleaner, set the ultrasonic frequency to 60KHz, and ultrasonically clean for 10 minutes;

[0009] A2: Feed the ultrasonically cleaned rosemary branches and leaves into a crusher, set the crushing particle size to 3 - 5mm, and crush for 30 minutes. After crushing, obtain rosemary segments;

[0010] A3: Feed the rosemary segments into the reaction chamber of the distiller. During the placement process, pay attention to placing them loosely and do not compact them.
