Description

Technical Field

[0001] The invention relates to the technical field of skin care products, and in particular to a compound essential oil for alleviating skin aging and a preparation method thereof. Background Art

[0002] Due to the rapid development of today's society, changes in the internal and external environment and increased mental stress have led to more and more women experiencing premature aging. In particular, women aged 40 to 50 have entered a comprehensive aging stage due to decreased estrogen levels, increased iron deposition, and excessive loss of collagen. Skin aging is gradually becoming more obvious. Skin aging not only affects beauty, but also causes many skin diseases, such as pruritus and skin keratosis. Among them, wrinkles are an important sign of skin aging and are also the focus of anti-aging.

[0003] Currently, there are many methods for treating aging, such as: (1) Skin care product repair therapy: Use skin care products with antioxidants such as vitamin A, vitamin E, and vitamin C to resist the damage of ultraviolet rays and other free radicals, help fade fine wrinkles, promote collagen deposition, and improve the physiological function of the skin, thereby achieving the purpose of anti-aging. However, in recent years, anti-aging cosmetics have problems such as ineffectiveness, long action period, and lack of standardized raw materials, which can easily cause other skin health problems.

[0004] (2) Estrogen replacement therapy: Transdermal estrogen supplementation therapy such as Itelite can replenish the epidermal growth factor, cell protection factor and cell activation factor required for skin cell renewal or repair in a timely manner, so that skin cells can always maintain a normal, young and healthy state. However, this therapy can increase the risk of heart disease, stroke, blood clots, endometrial cancer and breast cancer.

[0005] (3) Diet therapy: by supplementing the body's intake of foods rich in antioxidant vitamins, special antioxidant nutrients and trace elements, such as honey, peanuts, sesame seeds, ginger, turtles, beans, apples, etc., the purpose of beauty and anti-aging can be achieved. However, the progress of diet therapy is slow and must be persisted.

[0006] In general, there are various anti-aging drugs and skin care products with moisturizing and beauty functions on the market, but there are problems such as poor efficacy, many adverse reactions, inconvenience in use, and high prices. In addition, most skin care products contain more or less chemical raw materials.

[0007] In recent years, as consumers' natural, green and safe consumption concepts have been strengthened, people have put forward more requirements for skin care products. How to effectively avoid the "secondary damage" of chemical raw materials to the skin and use pure natural plant ingredients to resist skin aging is the current research direction.

[0017] d. The Himalayan cedar essential oil, frankincense essential oil, rock rose essential oil, lavender essential oil, helichrysum essential oil, petitgrain essential oil, rosewood essential oil, white orchid essential oil, jasmine essential oil, argan oil, camellia seed oil, and cactus seed oil obtained above are mixed to obtain essential oil.

[0018] Preferably, in step a), when the steam distillation method is used to extract the essential oils of each plant, the mass ratio of water to the crushed plant solid fragments is 4 to 6:1.

[0019] Preferably, in step b), when extracting the plant essential oil by supercritical extraction, the supercritical fluid used is CO2.

[0020] Preferably, the specific operating steps of extracting by supercritical extraction are: using cooling water to cool CO2 into a liquid state, using a high-pressure pump to push the liquid CO2 into a supercritical extraction device to ensure that the CO2 reaches a supercritical condition and becomes a CO2 supercritical fluid; using a preheater to preheat jasmine flowers and sending them into the supercritical extraction device, fully contacting the CO2 supercritical fluid and jasmine flowers in the supercritical extraction device, and dissolving the target components in the jasmine flowers; separating the CO2 supercritical fluid and the jasmine flower extract into gas and liquid in a separator, the CO2 becomes gaseous, and the jasmine flower extract remains in a liquid state; collecting the liquid phase component, which is jasmine essential oil.

[0021] Preferably, in step c), the specific process of extracting plant essential oil by cold pressing is: physical pressing by machine → separating the oil by centrifugal separator → filtering the extracted product and collecting the second filtrate, and the obtained second filtrate is the corresponding essential oil.

[0022] Preferably, the temperature during the mechanical physical pressing process does not exceed 60°C.

[0023] The alpha-pinene in the compound essential oil for alleviating skin aging of the present invention can cause DNA damage by generating active oxygen, thereby increasing lipid peroxidation to destroy cell membrane integrity and improve oxidase levels, and finally producing an antioxidant effect.
