Background technology
Camellia oil (also known as Wild camellia seed oil, tea-seed oil, camellia seed oil) is derived from the seed of tea oil tree.The manufacturing process of camellia oil
It can be divided into：Shell, dry, crush, extract oil, filtering, overall process is physical method, therefore it is real fully natural green food
With oil.Erucic acid, cholesterol, aflatoxins and other additives are free of in tea oil.After tested：Unrighted acid is up in tea oil
More than 90%, oleic acid reaches 80~83%, and linoleic acid reaches 7~13%, and is rich in protein and vitamin A, B, D, E etc., especially
It is that abundant leukotrienes contained by it is needed by human and can not synthesized.
Tea oil has five big characteristics,
1. the edible oil and fat with pollution-free food property：Tea oil is also known as camellia seed oil, and short, bristly hair or beard (cha) oil originates from wild tree
Kind-oil tea (tree), the tree is grown in high and steep mountains, it is not necessary to which labor management (as applied fertilizer, is sprayed insecticide), without any pollution.
2. it is easy to human consumption's absorption：In conventional edible oil and fat, high-quality aliphatic acid contained by tea oil at most (reaches 90.4
℅), saturated fatty acid (being commonly called as fat) content is minimum, without heavy erucic acid, is understood according to grease theory, tea oil portion big absolutely
Split-off, which is supported, to be easy to tissue and quickly absorbs.This property is also referred to as " skin-friendly ".
3. significant reducing blood lipid performance：Practical basis：No less than the practical experience of life of tens of millions of people.Because tea oil can be removed
Harmful blood fat (saturated fatty acid and cholesterol), so the effects such as it has blood clean, reduction blood viscosity and dredging vascellum.
The inoxidizability of the last 4.：Tea oil be typical oleic acid/linoleic acid grease, stronger inoxidizability be it is such not
The general character of saturated fatty acid；The vitamin E enriched contained by tea oil is generally acknowledged powerful antioxidant.
5. good biomembrane fluidity：Because tea oil has significant reducing blood lipid performance, so it can remove attachment
The metabolism of lipid and cholesterol on wall, dredges capillary and arteries in the blood vessels, and blood is moistened in increase blood vessel blood transfusion section, softening
Pipe, recovers its elasticity, blood vessel is kept young state.
And general camellia oil is divided into edible camellia oil and external-use skin care tea oil, edible-type tea oil typically selects fresh tea oil, always
Tea oil is used for skin effect more preferably, new tea oil alkalescence, and edible alkalescence is to healthy.By prolonged storage, tea oil
Acid value increase, become weakly acidic.The skin of people inherently weak acid, the cosmetics of weak acid are good to skin, so older
Tea oil to skin more it is good it is easier absorb.The general camellia oil seal that squeeze and filter is good, which is placed more than 10 years, to be referred to as always
Tea oil.
At present, existing many factors are proved relevant with aging, can be divided into Castle's intrinsic factor and extrinsic factor, wherein endogenous
Sexual factor maximum is injury of the free radical to body, for skin, and the maximum factor of exogenous aging is ultraviolet, outside
Property aging in source is otherwise known as " light aging ".When talking about anti-aging, we usually can be since anti-oxidant, removing free radical, freely
Base be a class very active bioactive molecule group (because the overwhelming majority contains free oxygen atom, be generally called oxygen from
By base) be typically body metabolism product.Free radical is endogenous aging factor be determined at present, most important, therefore, is resisted
Aging is exactly Green Tea Extract, anti-oxidant largely.If for external-use skin care, camellia oil needs sealing more than 10 years,
Need the time long, just can be more preferable for external-use skin care effect, even so, the camellia oil of oily is used for direct skin care, oil
Soapy feeling is not to be easy to allow people to receive.
