Problems solved by technology

Traditionally, ethanol solution (Tincture of iodine, iodine tincture, commonly known as iodine) formulated with iodine is used, because its solvent is ethanol, which is irritating and cannot be used in patients with alcohol allergies; iodine complexed by surfactants and iodine Iodophor (Iodophor) is an unstable water-soluble disinfectant and detergent, which can be used as a replacement product for iodine, but has a disgusting iodine odor; ZL93101603.7 "Aromatic Iodine" announced by China Patent Office on June 25, 1997 "V", adding benzaldehyde as a flavoring agent on the basis of commercially available iodophor is an improvement, but the amount of sodium lauryl polyoxyethylene sulfate used in it is too large (the content in the finished product can reach 5-55%) , it is an anionic surfactant, and the literature on the toxicity of surfactants was reported in the 1970s

Embodiment 1

[0024] Example 1 Preparation of 2% (W / W) atomic iodine aqueous solution Iodine: cosolvent: water = 1:5: balance.

[0025] Co-solvent adopts β-cyclodextrin, its main technical indicators: appearance white powder, non-toxic, odorless, slightly sweet; content ≥ 99%; moisture ≤ 0.5%; residue on ignition ≤ 0.3%; heavy metal content (calculated as Pb )≤0.00001%; ​​arsenic (As) content≤0.00001%. Products of Shandong Xinda Fine Chemical Co., Ltd.

[0026] Including the following steps:

[0027] ① Grind 5g of iodine in a mortar, and prepare an ethanol solution of iodine with a dissolved amount of ethanol at 65-70°C (about 10ml, the amount is controlled so that the iodine can be completely dissolved during the preparation process);

[0028] ②Under the condition of 65~70℃, dissolve 5g of β-cyclodextrin in 50ml of water to prepare a saturated aqueous solution of co-solvent β-cyclodextrin;

[0029] ③Under stirring conditions at 65-70°C, pour the ethanol solution of iodine into the satur...

Embodiment 2

[0031] Example 2 Preparation of 30% (W / W) atomic iodine aqueous solution Iodine: cosolvent: water = 1:1: balance.

[0032] The auxiliary solvent is α-cyclodextrin, the amount of water is increased or decreased according to the calculated amount, and 0.01% benzaldehyde by weight of the solution is added, and the remainder is the same as in Example 1.

Embodiment 3

[0033] Example 3 Preparation of 20% (W / W) atomic iodine aqueous solution Iodine: cosolvent: water = 1:4: balance.

[0034] Cosolvent adopts γ-cyclodextrin, the amount of water is increased or decreased according to the calculated amount, and 0.1% benzaldehyde by weight of the solution is added, and the remainder is the same as Example 1.

Abstract

The present invention relates to inorganic sterilizing chemicals. The aqueous solution of atomic iodine consists of iodine in 0.5-30 wt%, cosolvent cyclodextrin derivative and water. It is compoundedthrough preparation of ethanol alcohol solution of iodine and saturated water solution of cyclodextrin derivative at 35-70 deg.c, mixing, and diluting with water to the said iodine content. The macromolecule of cyclodextrin as cosolvent can raise the solution degree of iodine, convert insoluble iodine into water soluble micron level iodine and thus increase the stability of medicine. The presentinvnetion has strong sterilization, no irritation to skin, mucous membrane and other sensitive parts and no toxic side effect, and is used as substitute of iodine tincture and iodoform.

Description

technical field [0001] The invention belongs to the category of disinfection products containing inorganic active ingredients, in particular to an atomic iodine aqueous solution and a preparation method thereof. Background technique [0002] Iodine can oxidize the active group of the protoplasmic protein of bacteria, and can also combine with its amino group to denature the protein, so it has a strong effect of killing common bacteria, fungi, viruses and protozoa. Traditionally, ethanol solution (Tincture of iodine, iodine tincture, commonly known as iodine) formulated with iodine is used, because its solvent is ethanol, which is irritating and cannot be used for patients with alcohol allergies; iodine complexed by surfactants and iodine Iodophor (Iodophor) is an unstable water-soluble disinfectant and detergent, which can be used as a replacement product for iodine, but has a disgusting iodine odor; ZL93101603.7 "Aromatic Iodine" announced by China Patent Office on June 25,...
