The core of the additive is aluminum lactate, and the main ingredients of the liposome include lecithin, cholesterin and vitamin E.
Description
Technical field
The invention belongs to the additive technology field in the fine chemicals, relate to a kind of aluctyl. additive, relate in particular to a kind of nanometer grade liposome aluctyl. additive that is used for cosmetics of everyday use.
Background technology
Aluctyl. (Aluminum Lactate), molecular formula Al[CH
3CH (OH) COO]
3, molecular weight 294.20, white or yellow powder shape solid, soluble in water.
In recent years, countries such as the U.S., Japan, Britain, Germany have carried out big quantity research to the application and development and the biological characteristics of aluctyl., test shows that aluctyl. is the novel interpolation reagent of cosmetics of everyday use determined of a kind of effect ([J] such as application/Xu Hong, the Gou Jing of aluctyl. in daily-use chemical industry, Chen Xin, " daily chemical industry ", 2001,5:64-65,68).Be applied in the toothpaste as aluctyl., can prevent and cure odontohyperesthesia; Aluctyl. makes an addition in the cosmeticses of everyday use such as the deodorizer of human body skin, the emulsion of going acne, skin protection facial cream, colorful lip pomade, hair jelly, anti-perspirant, shampoo, liquid cleaner, is a kind of active substance, plays effects such as stable, convergence, sterilization.In the prior art, problem such as aluctyl. is to add in the cosmetics of everyday use with the pressed powder state as additive, exists penetration not good enough, and biocompatibility is undesirable.
Nowadays, obtained good effect with nanometer grade liposome as the cosmetics of everyday use additive carrier, nanometer grade liposome is a kind of novel control delivery, it can overcome emulsion carrier and add the physical instability that occurs after traditional cosmetics of everyday use additive, and additive is easy to shortcomings such as leakage; Also can overcome macromolecular material, polymer particles and polymer nanoparticle (polymeric material commonly used has polylactic acid, lactic acid-ethanol copolymer, paracyanogen base alkyl acrylate etc.) shortcoming as carrier, if any cytotoxicity, accumulation easily in vivo, unfavorable to human body, some prices of raw and semifnished materials costliness etc.The major ingredient of nanometer grade liposome is made up of biocompatibility, the good material of toleration, because particle diameter is very little, liposome has similar adhesion characteristic, can form film on skin, the damaged adipose membrane on can repair of skin, good stability.Therefore, above-mentioned aluctyl. being prepared into nanometer grade liposome aluctyl. additive is used for cosmetics of everyday use and can produces the effect more excellent than aluctyl. undoubtedly.
But, at specific cosmetics of everyday use additive aluctyl., want the next level liposome of receiving of an obtained performance excellence aluctyl. additive, how to select the major ingredient of suitable nanometer grade liposome, need to adopt what kind of processing step, process conditions, these all are that prior art can't directly be instructed acquisition, also have many technical difficult problems.
Summary of the invention
The object of the present invention is to provide a kind of nanometer grade liposome aluctyl. additive that is used for cosmetics of everyday use, select the major ingredient of suitable nanometer grade liposome, by selecting specific processing step and process conditions, obtain nanometer grade liposome aluctyl. additive with higher envelop rate and preferable particle size range.
The objective of the invention is to realize by the following method:
The nanometer grade liposome aluctyl. additive that is used for cosmetics of everyday use is to be the liposome major ingredient with lecithin, cholesterol, vitamin E, the liposome major ingredient is dissolved, seal aluctyl. behind the formation lipid film and obtain nanometer grade liposome aluctyl. additive suspension or solid, preparation process is as follows:
(a) liposome major ingredient dissolving: with mass ratio is that the volume ratio that 1.0: 0.5～1.0: 0.1～0.8 lecithin, cholesterol, vitamin E are dissolved in 10～20mL is in the mixed solvent of 0.5～1.5 absolute methanol/chloroform, and wherein lecithin content is 2.5～10mg/mL.
(b) lipid film forms: under 30～60 ℃ of conditions, remove fully with speed reduction vaporization to mixed solvent on Rotary Evaporators of 60～90r/min, the round-bottomed flask inwall forms one deck homogeneous film.
(c) adding of encapsulation object: (diameter 0.1～0.5mm) mode adds 15～20mL in the flask to (b) step, and to be dissolved with mass ratio be 0.5～2 the nonionic surfactant and the aqueous solution of aluctyl. with continual small fluid column.
(d) the nanometer liposome mixed liquor forms: under 500～1200r/min condition, and magnetic agitation 4～6h.Then, at room temperature ultrasonic 5～20min in ultrasonic generator promptly gets the nanometer liposome mixed liquor that wraps up aluctyl..
(e) nanometer liposome turbid liquor forms: it is 8000～12000 bag filter that this mixed liquor is placed the molecular weight that dams, dialysis 24～48h in 0～4 ℃ PBS buffer solution (pH=7.4 ± 0.1), remove free non-encapsulated aluctyl., promptly get the nanometer liposome turbid liquor of sealing aluctyl., envelop rate is 70 ± 10%.
Further also the nanometer liposome turbid liquor of aluctyl. can be made the nanometer liposome solid: do lyophilized preparation with 50～200mg glucide, nanometer liposome turbid liquor is freezed to rapidly-60～-40 ℃, lyophilization 36～72h on the freezer dryer promptly gets the powder needle-like solid.The nanometer liposome solid can be stablized preservation 3 months under 0～4 ℃ of condition.
Nanometer liposome characterizes: this powder needle-like solid is water-soluble, be diluted to colourless transparent solution, and observation is spherical under transmission electron microscope, is evenly distributed, and particle size range is about 100～300nm.
Advantage of the present invention mainly shows the following aspects:
1, additive is an aluctyl., has good anti-dentin hypersensitiveness, skin contraction and bactericidal action;
2, additive has better biocompatibility with the carrier of liposome as aluctyl. with human body skin, and effect is continual and steady; The liposome major ingredient is selected for use to lecithin, cholesterol, vitamin E, and is safe, has no adverse effects.
3, liposome is the bimolecular hollow ball structure, loads water soluble ingredient aluctyl., envelop rate height in the middle of ball.
4, the particle diameter of additive is a nanoscale, because when corpuscle reaches nano-scale, some character of material will be undergone mutation, and many new kink characteristics occur, have characteristics such as quantum size effect, small-size effect, skin effect, macroscopic quantum effect as nano material.Therefore, strengthen the biological agent of additive, higher penetration has been arranged, helped bringing into play its biological effect, active high; Environmentally friendly, be a kind of ideal novel cosmetics of everyday use additive, can be widely used in the cosmeticses of everyday use such as toothpaste, deodorizer, emulsion, facial cream, lip pomade, hair jelly, anti-perspirant, shampoo, liquid cleaner.
5, obtain nanometer grade liposome aluctyl. additive by above-mentioned specific processing step and process conditions, can make the particle diameter of additive be controlled at 100～300nm scope, higher penetration is arranged; And preparation technology is simple, and easy to operate, cost is lower, good reproducibility, and the envelop rate height can be used as the foundation of scale-up.
