New cosmetic raw material - shea butter

During plant growth, they carry out many metabolic and biochemical processes, forming and accumulating various chemicals Substances that form the chemical components of plants. Plant extracts are very complex and also contain a variety of chemical components, no The composition of the same parts is also different. Usually plants contain a variety of chemical components: alkaloids, glycosides, organic，Acids, resins (including resinous acids, resinous alcohols and hydrocarbon resins), volatile oils, sugars (including starch, inulin,Gum and mucus, etc.), amino acids, proteins and enzymes, tannins, plant Extract pigments (including chlorophyll, carotenoids Foraphane, flavonoids, betaine and quinones, etc.), oils and waxes, and inorganic ingredients (trace elements).

There are many varieties of Herbal Extract whose main functions are included in skin medicine, efficacy cosmetics and cosmetics Including: anti-irritation, anti-inflammation, wound healing, anti-infection, sterilization, wetting, skin protection, etc., none Whether it is a single plant extract or a compound extract, it often has multiple effects, especially compound The clinical efficacy of the extract is reflected in the synthesis and overall effect of the combination, and its efficacy is sometimes purer than that of the isolation.

The mixture of chemical components is Boosting immunity extract more excellent. According to the formula of plant extracts, it can be divided into: water-soluble plant extracts (including water and propylene glycol, Propylene glycol, butanediol and glycerol extracts), oil-soluble plant extracts (including various vegetable oils, such as sunflower) Flower seed oil, coconut oil and olive extract oil, sometimes using isopropyl myristate extract) essential oil, spray Mist drying powder, enzymatic hydrolyzed plant protein powder, pure active ingredient, peeled fruit core powder, liposome microcapsules, polysaccharide Or other porous polymer microcapsules and microspheres adsorbed extracts. It is also used in freshly prepared fruit or vegetable juices Professional beauty salon or home.

If the plant part used for the plant extract is Sleeping aid extract diffrent, the active ingredient is different, Including: roots, stems, leaves, bark, flowers, garlands, fruits, seeds, shoots, etc. This classification method is in The preparation, application, storage and transportation aspects are more meaningful and are very useful in the manufacture of some plant extracts Quotient is often used. With the development of extraction, separation, composition and structure determination techniques and pharmacological effects, some The separation and purification of plant extracts began to receive attention, and some plant extracts production enterprises are actively studying And develop these new types of products.

Some of the larger cosmetics companies have done a lot of research work, points Isolate and extract pure extracts and further apply to various products. This plant extract contains highly effective chemicals Contains or does not contain other unrelated substances, but contains one or more pure ingredients. These ingredients are accurate The chemical composition and chemical composition content and structural composition, relatively clear quality standards and inspection methods, andPharmacological test, clinical test and activity test of its products were carried out.

The application of such plant extracts is more effective, It is more practical to facilitate product corrosion protection and quality control, but generally we will discuss some of the applications below Plant extracts in cosmetics, they have a clear composition and structure, and have been isolated and purified. Plant extracts are made from plants as raw materials and processed according to the needs for the use of the extracted final product Physicochemical extraction separation process, the directed acquisition and concentration of one or more active ingredients in plants, while A product formed without changing the structure of its active ingredients.

According to the different components of the extracted plant, glycosides, acids,Polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc. According to different characters, it can be divided into vegetable oil, extract, Powder, lens, etc. Plant extracts can be used in health industry, pharmaceutical industry, feed industry, food industry, The beauty industry and other industries. There are many kinds of plant extracts, and at present, more than 2000 kinds of plant extracts are produced in China More than 5,000 companies. In 2017, China's plant extract industry sales revenue of about 17.23 billion yuan, the amount of imports About 3.79 billion yuan, the export amount is about 13.57 billion yuan, the domestic plant extract industry market size is about 7.45 billion yuan

Avocado jelly (sB) has been used as an excellent new cosmetic raw material in Africa and European countries for hundreds of years. However, it has only been recognized in China in recent years. There are still few reports on the research of avocado, and the author will focus on the basic composition, characteristics and application of it in the cosmetics industry.

1 source of avocado

Avocado is found in the fruit of a woody oil plant, Shea, grown in the western and central African regions where there is little rain and dry heat. It is a new natural oil raw material. China was introduced in the dry heat valley of Yuanjiang, Yunnan Province in the 1970s. Usually, shea is 4m to 13m high with milk. The flowering period is from December of the following year to February of the next year. The fruit period is from April to June. The berry is spherical and the diameter is 4cm~5cm. It is brown when mature.

In Africa, the outer nuts can be eaten in March and April, and the content of avocado in the innermost chocolate-colored pits is 45% to 55%. The oil content of the avocado nuts from Yuanjiang, Yunnan, China is about 48% to 56%. Every year, Henkel of Germany and Fancor Cosmetics Raw Materials of the United States go to West Africa to buy shea nuts and process them into primary refining oil, and then refine and purify them in Europe or North America. The avocados used in cosmetics and chocolate in China are mainly from these two companies.

2 composition and characteristics of avocado

The avocado lipid is mainly composed of monounsaturated triglyceride, and its appearance is hard paste-like. It is softly covered with small granular crystals. It has a large odor before refining. The color is yellow or light green according to its processing and production process, and it has a light after refining. The unique aroma of avocado trees is white, making storage and transportation extremely convenient.

The glyceride component of avocado is mainly glyceryl oleate distearate (45.9%), glyceryl dioleate stearate (45.0%), glyceryl oleate palmitate stearate, glycerin Palmitic acid stearate and glycerol trioleate (6.8%).
