Embodiment 1

[0041] see figure 1 , the silver phytate preparation process:

[0042] 1. Add silver nitrate to the phytic acid solution with a concentration of 6-10%, adjust the pH to 8-10 with citric acid monohydrate, and stir for 2 hours; use a constant temperature device to maintain the temperature at 80-95°C.

[0043] The salt-forming reaction is:

[0044] 2. After the salt-forming reaction is completed, the reaction solution is concentrated for 4 hours.

[0045] 3. Cool the concentrated solution to 5±2°C, add anhydrous acetone, the amount of anhydrous acetone added is 0.9 to 1.1 times the mass of the concentrated solution, and precipitates out.

[0046] 4. Dehydrate and dry the precipitate to obtain crystalline silver phytate.

[0047] Table 1 Comparison of silver phytate preparation experiments

[0048]

[0049] It can be seen from Table 1 that during the preparation of silver phytate, the reaction is better when the concentration of phytic acid is 10%, the pH is 10, ...

Embodiment 2

[0051] see figure 2 , silver phytate soap preparation process:

[0052] 1, palm oil is hydrolyzed to generate sodium carboxylate under the effect of sodium hydroxide, and the sodium carboxylate solution that obtains mass concentration is 35%.

[0053] The saponification reaction is: RCOOR+NaOH→RCOONa+ROH

[0054] Palm oil is mild to the skin and has strong cleaning power; the oleic acid content is 40%, and the moisturizing power is strong; the INS value is 145. The saponification reaction can be carried out between 25°C and 70°C, and the saponification reaction is best performed at a temperature of 50°C.

[0055] 2. After the silver phytate prepared by the third group of embodiment 1 was pulverized and crossed a 300 mesh sieve, it was added to react in the RCOONa solution;

[0056] The metathesis reaction is: RCOONa+Ag 12 C 6 N 6 o 24 P 6 → RCOOAg

[0057] The mass ratio of the silver phytate to the sodium carboxylate solution is 0.01-0.2:1, the temperature is contro...

Abstract

The invention relates to the field of toilet soap and provides phytic acid silver toilet soap and a preparation method thereof. The phytic acid silver toilet soap comprises phytic acid silver, wherein the phytic acid silver accounts for 0.01 to 0.5 percent of the mass of the toilet soap. The preparation method for the phytic acid silver toile soap comprises the following steps: hydrolyzing palm oil under the action of sodium hydroxide to generate sodium carboxylate solution, crushing phytic acid silver precipitate, adding the powder into the sodium carboxylate solution and reacting, wherein the pH value is adjusted to be 8 to 9 by citric acid monohydrate; and dehydrating, drying, adding essence and performing compression molding. The phytic acid silver toilet soap has a good effect of killing bacteria, viruses, fungi and other pathogenic microorganisms.

Description

technical field [0001] The invention relates to the field of soaps, in particular to a silver phytic acid soap and a preparation method thereof. Background technique [0002] Silver ions have excellent sterilization and detoxification effects. General antibiotics can only work on 6 kinds of bacteria on average, but silver ions can eliminate 650 kinds of bacteria. Silver ions can weaken the activity of enzymes in the germs, thereby preventing side effects and strengthening the resistance of germs, and fundamentally controlling the reproduction of germs. Ag+ can strongly adsorb the sulfhydryl group (-SH) on the protease in the bacterial body, and quickly combine with it to inactivate the protease and cause the death of the bacteria. When the bacteria are killed by Ag+, Ag+ will free from the dead body of the bacteria, and then contact with other colonies, and the above process will be repeated again and again, which is also the reason for the long-lasting bactericidal effect...
