Description
Technical field
The present invention relates to field of oral care, be specifically related to heterogeneous unilamelar liposome parcel restructuring epithelical cell growth factor
With tetrahydropyrimidine mixing water gel composition.
Background technology
Epithelical cell growth factor (Epidermai Growth Factor), is called for short EGF;It is that one is widely present in people
Skin Cell, body fluid, kidney and cerebral tissue in the biologically active polypeptide being made up of 53 aminoacid, be that one has physiology
The bioactive substance of function, has the strongest biological effect.In human body, the epithelical cell growth factor of denier is with regard to energy
Play the biggest biological action, propagation and the growth of skin tissue cell can be promoted, make newborn young cell replace rapidly
Aging and dead cell.It is periodically Skin Cell supplementary table skin cell growth factor, it is possible to persistently promote the synthesis of cell, protects
Hold the metabolism that epidermis cell is vigorous, also have and promote skin and mucosa wound healing, anti-inflammatory analgetic, prevent and treat effect of ulcer.
But epithelical cell growth factor content in human body cell and tissue is extremely low, limited source is expensive.
Someone passes through escherichia coli, bacillus brevis, yeast gene recombination technology and zooblast, plants the most successively
Thing cell, alga cells In vitro culture, it is achieved that restructuring epithelical cell growth factor (Recombinant epidermal
Growth factor, rhEGF) mass production.But in actual use, the stability of restructuring epithelical cell growth factor is subject to
To the impact of the factors such as temperature, pH value, protease, additive (antibacterial, antioxidant etc.), activity is made to be substantially reduced.As for
Ulcerative conditions, the enzyme of wound face can be degraded restructuring epithelical cell growth factor, needs to add enzyme inhibitor.
Tetrahydropyrimidine (Isosorbide-5-Nitrae, 5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid) is N-
A kind of pyrimidine derivatives that acetylizad DAB is formed by intramolecular dehydration, is the master in most of Halophilic Bacterium
Want compatible solute.Tetrahydropyrimidine can stablize the biomacromolecule such as the hydration layer of native protein, protective enzyme, DNA, RNA and
Membrane structure, helps the characteristic of the various non-specific environment such as cell resistance high salt, high temperature, low moisture, freezing and radiation.
Tetrahydropyrimidine is compounded as a kind of protective agent and restructuring epithelical cell growth factor, on the one hand can protect restructuring
Epithelical cell growth factor is not affected by factors such as temperature, pH value, protease, additives (antibacterial, antioxidant etc.);Another
Aspect can protect the regenerative cell at inflammation, ulcer, wound surface.
Summary of the invention uses liposome can also improve the stability of biological preparation simultaneously.Liposome is in cosmetics
Application comparison many, mainly include two aspects: one, liposome avoids bioactive substance mutual as the carrier of functional components
Effect or generation biodegradation;Two, the phospholipid in liposome membrane and unsaturated fatty acid itself have good moisturizing and skin protection
Effect.Liposome particularly its lipoid similar to skin composition, the liposome formed such as sphingomyelin and skin keratin
Layer lipid has high similarity, can increase the medicine accumulation at local skin, strengthens skin targeting, and can sustained release medicine
Thing;There is the effect strengthened in medicine entrance horny layer and epidermis lipoid.
It is substantially the topical for skin that liposome is applied in cosmetics: designing fat with skin for targeting moiety
During plastid, retain in skin with should making medicine maximum, enter blood circulation as little as possible, i.e. effectiveness composition acts on skin
The horny layer on skin surface or enter epidermis or corium.I.e. liposome and other functional components transdermal penetration to be realized in cosmetics
And avoid entering blood circulation through skin, cause toxic and side effects. simultaneously.At present, the research of liposome percutaneous dosing shows: fat
The plastid particle diameter liposome more than 1000nm is mainly stranded in horny layer;The liposome of 600nm-1000nm can penetrate into epidermis
Layer and skin corium;Liposome less than 200nm then can be directly entered systemic circulatory system, causes toxic and side effects.Further contemplate simultaneously
To different dosage forms, therefore, we select preparation method time based on the method preparing single chamber multiphasic liposomes.
Summary of the invention
It is an object of the invention to provide a kind of oral care composition, by tetrahydropyrimidine and restructuring epidermal growth because of
Son is compounding, and the most in addition liposome improves all drawbacks being used alone restructuring epithelical cell growth factor, the most right
Oral inflammation, ulcer prevention have the effect of Synergistic.
The above-mentioned purpose of the present invention is achieved by following scheme:
A kind of oral care composition, described oral care composition is thin by heterogeneous unilamelar liposome parcel restructuring epidermis
The intracellular growth factor and tetrahydropyrimidine mixing water-setting agent are constituted.
Described liposome accounts for the 80%-99.8% of composition weight, is made up of a phosphate and a quaternary ammonium salt base
Hydrophilic radical and the lipophilic group of two longer alkyl composition, mean diameter is between 600-1600nm.Wherein fat
Plastid is including at least one or more compositions in lecithin, cholesterol, ceramide, sphingomyelins.
Described restructuring epithelical cell growth factor accounts for the 0.1-10.0% of composition weight, and its concentration is 100-
2000mg/kg, molecular weight is 5900-6500Da, and sedimentation coefficient is 1.20-1.30S, and isoelectric point, IP is pH4.5-4.9, for lyophilized powder
Shape.
Described tetrahydropyrimidine accounts for the 0.1-10.0% of composition quality ratio, and purity is 99%-100%, for powdery.
Compared with prior art, the method have the advantages that:
1, tetrahydropyrimidine can protect restructuring epithelical cell growth factor, (is not pressed down by temperature, pH value, protease, additive
Microbial inoculum, antioxidant etc.) etc. the impact of factor and reduce activity, it is provided that the stability of use.
2, tetrahydropyrimidine itself has protective effect to regenerative cell, and restructuring epithelical cell growth factor is to stomatitis
Disease, ulcer prevention have the effect of Synergistic.Such as make ulcer surface regenerative cell no longer be invaded and harassed by the secondary of antibacterial, accelerate to increase
Grow.
3, the oral care implement compositions that the present invention provides uses single chamber multiphasic liposomes parcel form, and liposome is to two
Plant biological preparation and protection is provided, meet the requirement of the different conditions such as water preparation and Emulsion, improve the stability of compositions simultaneously.
