Description
Technical field
The present invention relates to oral care composition, it is specifically related to containing lauroyl arginine ethyl ester derivative (ion pair
Compound) oral care composition, the lauroyl arginine ethyl ester ion pair have antibacterial effect, oral care can be helped
Composition is while playing it and cleaning the teeth, treats or prevents odontopathy, moreover it is possible to keep composition stable and play antibacterial imitating
Fruit.
Background technique
Plaque is the soft sludge formed on tooth, and the accumulation including bacterium and bacterial by-products.In addition to not
Except refined, bacterial plaque is also related with the generation of gingivitis and the periodontosis of other forms.It has proposed cationic antibacterial agent
(for example, being based on arginic ester, Sn (II) compound, cetylpyridinium chloride) is used for oral care, and especially uses
To resist bacterial plaque formation and form relevant mouth infection to bacterial plaque.However, these reagents usually with dentifrice (i.e. mouthwash,
Toothpaste, tooth powder and chewing gum) in visible other compositions it is incompatible, to reduce its antimicrobial work in the preparation
Property.
Due to the almost epidemic incidence of dental erosion, oral care composition (such as dentifrice) how is improved
Antimicrobial acivity and stability, there is lasting demands.
Lauroyl arginine ethyl ester (Ethyl lauroyl arginate, LAE) is one kind by fatty acid and binary amino
Organic matter made of acid condensation is white hygroscopic solid, and chemical property is stablized in the range of pH3~7,50~58 DEG C of fusing point,
The LAE of 247g is dispersed in the water of 1kg at this temperature, its distribution coefficient in water and in oil is greater than 10, that is, is primarily present in
In water phase.The study found that lauroyl arginine ethyl ester LAE has, strong antibacterial, bio-toxicity is low, internal metabolic effects are good,
The high feature of being compatible with the environment property.And wherein most representative feature is the metabolism noresidue of lauroyl arginine ethyl ester, it is related
Researches show that lauroyl arginine ethyl esters can quickly carry out natural metabolism in human body and animal body, is hydrolyzed into laurel first
Acyl arginine (LAS) and ethyl alcohol, LAS is hydrolyzed to naturally occurring dietary ingredient lauric acid and arginine, lauric acid again later
It can be further metabolized carbon dioxide and water, arginine is then metabolized as ornithine, urea and carbon dioxide.Lauroyl essence
Generated all metabolites and final product are all nontoxic in propylhomoserin ethyl ester metabolic process, with humans and animals
The metabolite of the food of daily ingestion in vivo is identical.
2005, it was GRAS (generally accepted safety) based food additive that U.S. FDA, which ratifies LAE, had passed through Europe within 2007
The safety food of continent food safety management office (EFSA) authenticates, and LAE is included in food additive by Codex Alimentary Commission in 2011
Add in the general code standard of agent, license LAE is as preservative in 20 numerous foods and fresh agricultural products.
Chinese invention patent 200980104596.7, " using cationic surfactant protect tooth erosion " disclose with
LAE is as cationic surfactant as the composition forms application orally used, the oral care group orally used
Closing object is, for example, sweet food, candy, tablet, lozenge, lollipop, toffee, jelly, glycocoll, drops or the drink for being intended for use in dissolution
The powder mixture of feed powder, wherein the LAE compound is with by weight 0.001% to 5%, preferably by weight 0.001%
Concentration to 2% is present in composition.In the composition, due to LAE presence and generate microbial change rules, and provide
The source for neutralizing bacterial plaque acid, obtains good effect.
Chinese invention patent 201480081262.3 " includes peroxide source and N- acetyl-L-arginine alkyl ester salt
Mouthrinse composition " discloses LAE and its salt and hydrogen peroxide (H2O2) proportion mouthwash, wherein the LAE and its salt are to press
The concentration of poidometer 0.05% to 0.4%, preferably by weight 0.1% to 0.3% is present in composition, can have
Effectively whitening and antimicrobial acivity double effects, and the effect can brighten work described in passage maintenance at any time
Property and antimicrobial acivity.
In conclusion having carried out the research to LAE in the prior art, but it yet there are no and LAE derivative is used to prepare mouth
The relevant report of chamber nursing product.

Bacterium effect.
Embodiment eight: suspension quantitative method tests the effect that oral care product kills oral bacteria
Mouthrinse composition as shown in Table 2 is prepared using conventional method, removes H2O2Indicate outer with volume, remaining group component
It is indicated with mass percent (%).Wherein, control 1-2 is to contain cetylpyridinium chloride (CPC) and/or H2O2Mouthwash,
Negative control is blank water.
Streptococcus oralis (ATCC:43146) is seeded to 50mL dextrose bouillon, 37 degree of cultures are for 24 hours.
1ml culture is drawn, with 20000g centrifugation 10 minutes, separation of bacterial precipitating.Then, by cell precipitation resuspension
Afterwards, take 100 μ l drops in 5ml test fluid, after mixing, respectively at 2min, 5min, 10min, 20min.Then, it takes
0.5ml mixed liquor is placed in 5ML PBS test tube, is mixed and is suitably diluted, then takes 2-3 dilution, draw 0.5ml respectively,
Two plates are placed in, is poured into bacteria Agr culture medium, plate is overturn after solidification, with 37 degree of culture 48h, bacterium colony meter of laboring
Number.
Test is repeated 3 times, and calculates bacteriostasis rate:
Bacteriostasis rate=(A-B) × 100%/A
Wherein, A=control sample average colony number
B=test sample average colony number
The results are shown in Table 2.
Table 2
Interpretation of result:
Fungistatic effect testing result shows, 0.01% LAE acetato- is to having been achieved with close to hexadecyl
Pyridine (CPC) and H2O2Combination effect, but be better than single use H2O2Fungistatic effect.
Although in above-mentioned experiment, the fungistatic effect and detergency of 0.2% dosage group are highests, and first from applicant
(denomination of invention: " lauroyl arginine ethyl ester derivative and the use as animal antibacterial agent from the point of view of the patent application of submission
On the way ", application number: 201810648982.3) from the point of view of cell assay in vitro data, 0.0032% concentration has generated antibacterial effect
Fruit, and fungistatic effect can be improved in LAE and its a certain range of dosage increasing of derivative, but relative to 0.1% dosage group
Fungistatic effect does not increase significantly, illustrates that the dosage range of 0.01%-0.2% has met production needs
In addition, being made in regulation using concentration guidelines according to existing relevant national standard (GB15797-2002, appendix C 4)
With in the time, if bacteriostasis rate is to have bacteriostasis in 50-90%, > 90% is stronger bacteriostasis.Although improve LAE and its
The additive amount of derivative can correspondingly increase bacteriostasis rate, but excessively high bacteriostasis rate means more residual, is not conducive to human body
Health.Even so, the bacteriostatic agent due to LAE and its derivative of the invention is at belonging to the nontoxic ingredient of natural environmental-protective, because
The addition of this high dose has the advantages that using still than traditional chemicals bacteriostatic agent friendly to human body affine.
Accordingly, it is considered to arrive production cost and needs of production, therefore LAE and its ion pair are cleaned as kitchen greasy dirt
