Description
Technical field
The invention belongs to technical field of nanometer material preparation, particularly to a kind of lignin nanometer of high ultraviolet protection performance
Particle and preparation method and application.
Background technology
In recent years, because ozone layer is constantly destroyed, the amount of ultraviolet irradiation reaching earth surface is caused constantly to increase.
In general, the ultraviolet that ozone layer reaches earth surface can be passed through to have two kinds: uvb region (280～320nm) and uva area
Domain (320～400nm).The ultraviolet in uvb region can direct sun-damaged skin, and uva region ultraviolet has to the injury of skin
Cumulative, permanent irradiation can cause skin aging to even result in skin carcinoma.Long-time ultraviolet radioactive can cause pole to human body skin
Big infringement, sun-proof skin care is very urgent.
Conventional sunscreen is generally divided into physics and chemical two big class.Physical sunscreen agent includes titanium dioxide, zinc oxide etc.
Can effective uv reflectance inorganic particle, these sunscreen easy catalytic degradation carbohydrate and high molecular polymer produce
Harmful free radical and free oxygen.Chemical sun mainly includes octyl methoxycinnamate (omc), dimethylaminobenzoic acid
The small molecules such as pentyl ester, oxybenzone and benzyl Camphora (4-mbc), these small molecules can effectively absorb the ultraviolet of different wave length, but
Content in sunscreen cream for these compositions is often as high as 25%, and there are some researches show that these small molecules are also easy to produce certainly under light illumination
By base, the product that free radical be combined with each other can destroy cellularity or change cellular morphology.No matter physics or chemical sunscreen
Agent, penetrates into skin inner layer and is easier to cause anaphylaxiss, small-molecule chemical sunscreen penetrates into intracellular being also easy to further
Cause dna variation.
The insecurity of the discomfort of physical sunscreen agent and chemical sun promotes people's growing interest to derive from plant
Natural sun-screening agents in thing.At present, the research extracting natural substance having sun-screening function from the several plants such as Flos Lonicerae, Aloe has been reported
Road, but because directly from natural plants, extraction cost is higher, the research of therefore this respect is in the laboratory research stage mostly
(journal of cosmetic dermatology,2014,14:47-63).Additionally, the concrete composition of these natural extracts
Not clear, the security performance of Photodegradation Products is unknown, is therefore difficult to large-scale production at this stage and promotes.
Lignin as a kind of natural polymer aromatic polymer from plant, itself contain substantial amounts of phenyl ring,
Carbonyl equiconjugate structure, the phenolic hydroxyl group having is not only advantageous to absorb ultraviolet, can remove free radical, therefore lignin simultaneously
There is good uv absorption and antioxygenic property.Lignin is applied to sun-proof shield as natural polymer broad spectrum sunscreen
Attempt in skin product.Masson Pine alkali lignin is mixed by qian etc. with the hand cream not having anti-sunlight function, in alkali lignin volume
SPF (sun protection factor) (spf value) for mixing white body when 10% reaches 5.72；By it, the sunscreen cream for 15 mixes with commercially available spf value
Close, alkali lignin volume is that the spf value mixing white body when 2% has reached 35.32, and volume spf value when 10% more reaches
89.58, illustrate the substance having sun-screening function in alkali lignin and sunscreen cream have synergism (green chemistry, 2015,17:
320-324).When organosolv lignin is mixed with hand cream, the spf value of the white body of mixing obtaining is higher, and 10% volume just reaches
To 8.66, its synergy more preferably (acs sustainable chemistry＆ with substance having sun-screening function in Commercial sunscreens frost
engineering,2016,4:4029-4035).
By self-assembled modified for the lignin color prepared Nano microsphere, lignin can be desalinated, improve its optical property
(industrial&engineering chemistry research,2014,53:10024-10028).But, lignin exists
Self assembly in selective solvent, generally requires lignin hydrophobic modification.Qiu Xueqing etc. is by after alkali lignin acetylated modification
Be dissolved in oxolane, add water driving self assembly successfully prepare acetylation lignin colloid ball (Qiu Xueqing, Li Hao, Deng Yonghong.
The acetylation of alkali lignin and its preparation of spherical micelle. macromolecule journal, 2014,11:1458-1464).On the one hand, tetrahydrochysene
Furan has carcinogenecity, is unfavorable for health；On the other hand, acetylated modification occurs on the phenolic hydroxyl group of lignin, phenol hydroxyl
Base is substituted the uv absorption property reducing lignin, sacrifice simultaneously lignin excellent antioxygenic property.Therefore, need
Develop a kind of green method that can prepare uniform and ordered lignin nanometer colloid ball without chemical modification, lifted wooden simultaneously
The sun-proof performance of element.

| Size lignin nanoparticle+2%parsol 1789 in blank frost body+10% | 15.04±0.25 |
As can be seen that when the middle sized nanostructures particle that organosolv lignin is prepared to, though its sun-proof performance is improved,
But it is obvious that the degree improving is not so good as small size lignin nanoparticle.But when the chemical small molecule sunscreen commonly using it with market
The sun-proof finger of the white body of mixing after avobenzone compounds, because it has cooperative effect and small molecule between, can be improved further
Number.The volume of central size lignin nanoparticle is 10%, when avobenzone volume is 2%, mixes the sun-proof of white body
Index also can reach 15, and the SPF (sun protection factor) meeting Commercial sunscreens frost requires.In addition, the preparation work of middle size lignin nanoparticle
Skill is more simple, easily produces in enormous quantities, is expected to substitute traditional sunscreen, becomes the harmless natural polymer ultraviolet of a new generation and prevents
Shield agent, has wide market prospect.
