Embodiment 1
[0031] Embodiment 1 A kind of luminescent tooth whitening gel, preparation method and application
[0032] 1) Luminescent tooth whitening gel and preparation method thereof
[0033] 1) Take 1.2kg of carbomer and add it to 28kg of deionized water, soak and swell at 70°C. After the carbomer is completely swollen, add 20kg of glycerin and 30kg of propylene glycol, stir at 70°C and 2500rpm for 22 hours, and mix well to obtain mixture A 1 ;
[0034] 2) Under the condition of maintaining stirring, the mixture A 1 Add 0.03kg disodium edetate and 0.07kg sodium saccharin in 3 batches, stir at 40°C and 2500rpm for 5h and mix evenly, then add 8kg of nanoporous zinc oxide, stir at 40°C and 2500rpm for 5h and mix evenly to obtain a mixture B 1 ;
[0035] 3) Mixture B 1 Add 12kg of phthalimide peroxyhexanoic acid, stir at 40°C and 2500rpm for 4 hours, and then check the pH value. According to the test results, add 0.5kg of triethanolamine, adjust the pH value to 6.0, and thicken After...
[0045] Examples 2 to 9 are respectively a luminescent tooth whitening gel, its preparation method and its application. Their steps are basically the same as those of Example 1, the only difference being the difference in process parameters. See Table 1 for details; their application process It is basically the same as Example 1, the difference is only the difference of trial parameters and results, see Table 2 for details:
[0046] List of each process parameter in table 1 embodiment 2~9
[0047]
[0048]
[0049] List of each process parameter in table 2 embodiment 2~9
[0050]
[0051]
[0052]
[0053] The subjects in Examples 2-9 are different people, and the content of other parts is the same as that of Example 1.

Abstract
The invention belongs to the technical field of tooth whitening, and discloses a luminescent tooth whitening gel, a preparation method and an application thereof. The raw materials for making the active ingredients of the luminescent tooth whitening gel include: phthalimide peroxycaproic acid, stable agent, photocatalyst, thickener, humectant, pH regulator, sweetener, essence and deionized water; the prepared luminescent tooth whitening gel is applied on the teeth, and the teeth are whitened by LED yellow light irradiation. Under the catalysis of photocatalyst, the phthalimide peroxyhexanoic acid in the present invention has enough free radicals in the strong oxide produced by decomposition, which promotes the rapid decomposition of the pigment tissue on the surface and deep layer of the tooth, and realizes rapid whitening Teeth; LED yellow light has low energy and mildness, and is less irritating to eyes and skin, which solves the problem of safety hazards in the use of high-intensity blue light and hydrogen peroxide in the process of cold light teeth whitening. The luminescent tooth whitening gel of the present invention is suitable for luminescent tooth whitening.
Description
technical field [0001] The invention belongs to the technical field of tooth whitening, and relates to a tooth whitening gel, in particular to a luminescent tooth whitening gel, a preparation method and an application. Background technique [0002] Cold light tooth whitening is a popular tooth whitening technology in Europe and America. It uses high-intensity blue light with a wavelength in the range of 480-520nm to irradiate the peroxide bleaching agent, so that the bleaching agent can penetrate the enamel and dentin tubules in a short time. The deposited pigment undergoes oxidation-reduction reaction to achieve whitening effect. Although the luminescent tooth whitening technology is relatively mature, there are still some problems in the luminescent tooth whitening products currently on the market. First of all, luminescent teeth whitening needs to apply a high-concentration peroxide-containing gel on the teeth, and the general peroxide is hydrogen peroxide. Hydrogen per...
