Problems solved by technology

However, the quaternary ammonium salt disinfectants on the market are not only few in variety, but also in a single dosage form, all of which are solutions, which not only have poor permeability but also have a short residence time on the surface of the object, and the disinfection effect lasts for a short time.

Embodiment 1

[0014] Embodiment 1, the preparation of the thickening type quaternary ammonium salt composition of stabilization

[0015] Unless otherwise specified, the sample contains 10% benzyltrimethylammonium chloride and 0.6%-1.2% hydroxypropyl cellulose. The preparation method of the composition is: mix hydroxypropyl cellulose with purified water, stir well, After the liquid is stable, slowly add benzyltrimethylammonium chloride solution (converted content) while stirring; add 0.5% water quality lemon essence, then use purified water to make up the volume, and after fully stirring, the thickened quaternary ammonium salt composition is obtained.

Embodiment 2

[0016] Embodiment 2, thickening type quaternary ammonium salt composition stability investigation and evaluation method

[0017] Unless otherwise stated, the following procedures were used for stability evaluation. The samples were placed in a 60°C oven. Measure the appearance properties and viscosity of the composition during the stability investigation, and in some cases also measure the content of benzyltrimethylammonium chloride active ingredient in the composition. Use the SYD-04 type full-automatic kinematic viscosity tester (produced by Jilin Dongfang Wei'an Science and Technology (Instrument) Co., Ltd.) to measure the viscosity of the composition, the viscosity unit is cP, and measure the content of benzyltrimethylammonium chloride by titrating with sodium tetraphenylborate concentration.

Embodiment 3

[0018] Embodiment 3, thickening type quaternary ammonium salt stability investigation test

[0019] This example shows the viscosity of a benzyltrimethylammonium chloride sample containing hypromellose thickener, fragrance and the variation of benzyltrimethylammonium chloride concentration therein. The following samples were prepared according to the general steps of Example 1, and the performance evaluation of the samples was carried out according to the stability investigation method of Example 2, and the results are listed in Table 1.

[0020] Sample 1 contained 10% benzyltrimethylammonium chloride and 0.6% hydroxypropyl cellulose.

[0021] Sample 2 contained 10% benzyltrimethylammonium chloride and 0.7% hydroxypropyl cellulose.

[0022] Sample 3 contained 10% benzyltrimethylammonium chloride and 0.9% hydroxypropyl cellulose.

[0023] Sample 4 contained 10% benzyltrimethylammonium chloride and 1.2% hydroxypropyl cellulose.

[0024] Table 1 Stability of benzyltrimethylamm...

Abstract

The present invention discloses a stabilized thickening quaternary ammonium compound which comprises the following components: quaternary ammonium, cellulose ester thickening agent and water. The compound has the advantages of transparency, easy dissolving into the water and stable capability. The stabilized thickening quaternary ammonium compound of the invention is suitable for sterilizing, cleaning and mildew prevention for household use, medical use and industrial use, eliminating algae in swimming pool, sterilizing in clothes washing process, daily sterilizing of pet, etc.

Description

technical field [0001] The present invention relates to stabilized thickened quaternary ammonium salt compositions. Specifically, the present invention relates to household, medical and industrial sterilization, disinfection, cleaning, mildew prevention, algae killing in swimming pools, disinfection in laundry process, daily disinfection of pets, etc. Background technique [0002] With the improvement of awareness of disease prevention and the expansion of pet breeding, more and more people have realized the importance of disinfection. The pursuit of safety, high efficiency and non-irritating, permeability and duration of disinfectants is the general psychology of consumers. Due to the disadvantages of the traditional hypochlorite solution, which is used in large amounts, due to its inherent disadvantages of irritating the mucous membranes and easily causing fabric discoloration, product manufacturers have developed alternative compositions based on quaternary ammonium salt...
