Description
Technical field
The present invention relates to a kind of anti-blue light skin protection cosmetics and preparation method thereof, belong to cosmetic field.
Background technique
Damage of the ultraviolet light to human skin in sunlight, most consumer compares concern, and usually has ignored visible
The damage to skin of light.At present in people's daily life, other than the blue light in sunlight, the blue light of electronic product production
Also it can not look down upon, with popularizing for electronic product, such as mobile phone, computer, TV, reading machine, LED light, also can produce blue light, increase
The risk for having added people to injure by blue light.
For blue light as one of visible light, wavelength is up to 400-500nm, obvious to the damage of skin.Blue light
It is that visible spectrum medium wavelength is most short, the highest wave band of energy, penetration capacity is stronger compared with ultraviolet light, so blue light is easier to permeate
To under skin skin corium, and a large amount of active oxygen can be generated under the radiation of blue light, excessive active oxygen can be such that collagen drops
Solution, causes oxidative damage, leads to skin aging, to cause serious damage to skin.
Specifically, people, which contact blue light for a long time or before sleeping, can not only upset the operating of human normal biological clock, can also lead
The reduction of internal melatonin is caused to cause a series of health problems such as insomnia.In daily life, people contact the frequency of blue light
Increasingly increase, so that skin over-exposure in blue light, reduces so as to cause self barrier maintenance ability of skin, aging is accelerated etc.
Consequence.Skin is exposed in visible light or high energy visible light KEV, so that Skin Cell can generate a series of following bad influences:
Such as: the increase of active oxygen, mitochondrial DNA damage, epidermal barrier reparation delay, cascade of response of inflammation increasing, Langerhans are thin
Born of the same parents' immunosupress etc..Therefore, as resisting UV or air pollution, it is also very necessary that protection skin resists blue light contamination, this
Help to slow down the early ageing and damage of skin.
It is spraying that citation [1] provides a kind of hydrosol, contains the following parts by weight: glycosylglycerol 0.01-3
Part, 0.01-5 parts of gentian root extract, 0.01-5 parts of flat peach Cactus Pedicel extract, 0.1-5 parts of silandiol salicylate,

Refluxing extraction is carried out after mixing after camellia is dry, crushing with the aqueous solution of alcohol, obtains extracting solution；
The extracting solution is concentrated, concentrate is obtained；
The concentrate is diluted using butanediol, obtains camellia flower extract.
Specifically, when preparing camellia flower extract, the temperature of the extraction is 60-70 DEG C, and the time of the extraction is
60-90min；In the aqueous solution of the alcohol, the mass concentration of alcohol is 65-85%, dry, smashed camellia and alcohol it is water-soluble
The mass ratio of liquid is 1:3-20；The number of extraction is 1-5 times, such as: it can be 3 times.
In terms of the gross mass of the anti-blue light skin protection cosmetics, the additional amount of camellia flower extract is 2-4%, such as:
2.2%, 2.5%, 2.8%, 3%, 3.2%, 3.5%, 3.8% etc..Also contain tea polyphenols in Camellia extract of the invention, it can
Lipid peroxidation is blocked to remove harmful free radicals.Harmful free radicals effect is removed when the additional amount of camellia flower extract is less than 2%
Fruit is bad, and when the additional amount of camellia flower extract is greater than 4%, cost is too high.
Safranine flower extract
Safranine flower extract is the safranine anthoxanthin extracted from safflower and safranine carthamin etc.；Safflower extracts
Object have the effects that promoting blood circulation, it is anti-inflammatory, anti-oxidant, by improve skin blood circulation, promote skin metabolism, remove freely
Base, inhibition melanin deposition, the decoloration of acceleration ecchymose removing, absorption ultraviolet light etc., play whitening, sun-proof, anti-aging function.
In the present invention, the preparation method of the safranine flower extract includes the steps that extracting from safflower using alcohol.
Specifically, the preparation method of the safranine flower extract includes:
Refluxing extraction is carried out after being mixed after safflower is dry, crushing with the aqueous solution of alcohol, obtains extracting solution；The alcohol
It can be ethyl alcohol, propyl alcohol, propylene glycol, glycerine etc., preferably ethyl alcohol.
The extracting solution is concentrated, concentrate is obtained；
The concentrate is diluted using butanediol, obtains safranine flower extract.
Specifically, when preparing safranine flower extract, the temperature of the extraction is 60-70 DEG C, and the time of the extraction is
60-90min；In the aqueous solution of the alcohol, the mass concentration of alcohol is 65-85%, dry, smashed safflower and alcohol it is water-soluble
The mass ratio of liquid is 1:3-20；The number of extraction is 1-5 times, such as: 3 is inferior.
In terms of the gross mass of the anti-blue light skin protection cosmetics, the additional amount of safranine flower extract is 1-4%, such as:
1.5%, 2%, 2.2%, 2.5%, 2.8%, 3%, 3.2%, 3.5%, 3.8% etc..In the present invention, safflower also has easypro
Slow antiallergic effect.When the additional amount of safranine flower extract is less than 1%, antiallergic releive act on it is bad；The addition of safranine flower extract
When amount is greater than 4%, cost is too high.
By the present invention in that collaboration can be generated with the combination of camellia flower extract, carrotene and safranine flower extract
Effect, to play the effect of anti-blue light.
Specifically, in the present invention, in terms of the gross mass of the anti-blue light skin protection cosmetics, the anti-blue light composition
Additional amount is 2-14%, preferably 4-14%, such as: 3%, 5%, 6%, 7%, 8%, 9%, 10%, 12% etc..Anti- blue light combination
There is preferable anti-blue light effect, anti-blue light effect is more excellent when additional amount is 4-14% when the additional amount of object is 2-14%.When anti-
The additional amount of blue light composition less than 2%, when anti-blue light it is ineffective, when the additional amount of anti-blue light composition be greater than 14% when,
Cost is too high and anti-blue light effect is without particularly apparent increase.
