Technical Field
The invention belongs to the technical field of deodorization, and particularly relates to a natural deodorant.
Background
At present, the odor of the deodorant on the market is mainly covered by essence or a mint component containing odor, and the fragrance emission is accelerated by alcohol, but the deodorant cannot eliminate the odor, and the odor can continue to appear after the essence is dispersed; in addition, the existing essence deodorant can not cover the peculiar smell of sulfur-containing, acid-containing or aldehyde-containing structures.
Although there is a method of adsorbing odor by using a macroporous polymer material such as activated carbon or zeolite, this method is suitable for treating odor having a small concentration range, and has disadvantages that the adsorption efficiency is low and the adsorption amount is small and odor is released due to saturation of adsorption for odor having a large concentration range.

The deodorant comprises tromethamine, the structural formula of which is shown as formula (I), is multifunctional amino alcohol, has excellent safety, and can capture aldehyde and fatty acid; common chemicals that produce off-flavors are isovaleric acid (3-methylbutanic acid), 2-nonenal (2-nonenal), propionic acid, and the like.
The reaction of tromethamine with aldehydes can form imines or oxazolidines, the reaction formula is shown in formula (II):
tromethamine can also react with acid to generate ammonium salt, so that the chemical substances generating peculiar smell become odorless and tasteless; and the tromethamine can also effectively react with formaldehyde and hydrogen sulfide to achieve the effects of indoor odor purification and removal of some harmful substances.
The content of tromethamine in the natural deodorant is 25-35%, and if the content is higher than 35%, the skin is easy to dry when the natural deodorant is sprayed on the skin, so that the experience feeling is poor; at 25%, it is difficult to remove some odors, such as foot odor, odor protein odor, etc.
The glycolipid in the deodorant is selected from one or two of sophorolipid and mannosylerythritol lipid, the sophorolipid has certain antibacterial, antifungal and antiviral activities, when the mass concentration of the sophorolipid reaches 1mg/mL, the inhibition rate of the sophorolipid on escherichia coli can reach 87%, the inhibition rate on bacillus subtilis can reach 91%, and the change of temperature does not influence the emulsification characteristic of the sophorolipid; the sophorolipid has irreversible damage to fungi in logarithmic growth phase and has good inhibition effect on plant-derived decay-causing fungi; in addition, the sophorolipid can quickly and effectively inhibit HIV virus, and has good inhibition effect on herpes virus, cytomegalovirus, influenza virus A, influenza virus B and influenza virus C and respiratory virus.
The content of glycolipid in natural deodorant is 8-12%, and when the content is higher than 12%, the transparency of the product is affected, especially under low temperature condition, and in addition, the content of glycolipid is higher than 12%, the cost of the product is increased by 30%; when the content is less than 8%, the bacteriostatic ability of the product is reduced, so that the scalp odor and the oral odor cannot be effectively removed.
The tea fermentation extract can effectively resist oxidation, and prevent rancidity and bacterial breeding caused by oxidation of oil; meanwhile, the skin moisturizing cream can stimulate and resist pollution and free radical damage to skin, and is beneficial to moisturizing and skin repair.
The content of the tea fermentation extract in the natural deodorant is 8-12%, if the content is higher than 12%, the transparency and stability of the product can be affected, the cost can be increased by 50%, and if the content is lower than 8%, on one hand, the efficiency of removing peculiar smell of the product can be reduced, and on the other hand, the moisturizing effect of the product can also be reduced.
The deodorant disclosed by the invention takes the three components as cores, can exert a deodorizing effect under different systems, is mild and safe, and has a skin repairing function and a moisturizing effect.
On the other hand, the embodiment of the invention also provides a preparation method of the natural deodorant, which is characterized in that tromethamine, glycolipid and tea fermentation extract are dissolved in water according to a proportion.
Preferably, the tromethamine and the glycolipid are added into water and stirred and dissolved at 37-50 ℃ to obtain a mixed solution; adding the tea fermentation extract into the mixed solution, and stirring uniformly at 22-28 deg.C.
