Problems solved by technology

Azadirachtin preparation products are unstable under natural environmental conditions and are prone to photolysis and hydrolysis. To solve the stability problem of azadirachtin preparation products has always restricted the development of product formulations.
The dosage forms of the currently developed azadirachtin series products are emulsifiable concentrates, water-dispersible granules, and microcapsules. Among them, the formulations of emulsifiable concentrates usually contain benzene aromatic hydrocarbon solvents, which are harmful to humans and animals; The packaging and dosage are small, so water-dispersible granules and microcapsules are inconvenient to use and difficult to increase dosage in the home gardening market

Abstract

The invention discloses azadirachtin effervescent tablets for household gardening. The azadirachtin effervescent tablets comprises the following raw materials by weight percent: 0.1-3% of azadirachtin, 1-20% of neem oil, 6-45% of a disintegrating agent, 1-20% of a wetting agent, 1-20% of a dispersing agent and the balance being supplemented filler, and the total weight percent is 100%. The invention also discloses a production process of the azadirachtin effervescent tablets for household gardening. The production process comprises the following steps of mixing all the raw materials; milling the mixed raw materials by using a jet mill, sieving powder by using 75-micron testing sieve so as to obtain fine-particle powder with the particle diameter being less than 75 microns; wetting and kneading the powder by using a little amount of bonding agent; carrying out tabletting by using a tabletting machine; carrying out drying treatment, controlling the temperature to be 18-21 DEG C, controlling the humidity to be 20%-25%, carrying out package after the bonding agent is completely evaporated so as to obtain the azadirachtin effervescent tablets. According to the azadirachtin effervescent tablets disclosed by the invention, the problem that azadirachtin products are blank in the household gardening market is well solved; when the azadirachtin effervescent tablets are used, the effective components are fully contacted with a target, the medicinal effect can be exerted well and the low-toxicity and environmental-friendly effects are achieved.

Description

technical field [0001] The invention relates to an effervescent tablet and a production process, in particular to an azadirachtin effervescent tablet for home gardening and a production process. Background technique [0002] Due to the high packaging cost, strict packaging requirements, and high product safety requirements of pesticides used in home gardening, many pesticide companies are discouraged from this market segment. Therefore, there are basically no pesticide products specially used in the home gardening market. Pesticides are used in small packages of general pesticides, resulting in a blank market for pesticides for home gardening. [0003] At present, the commercially available preparations used in the home gardening market are relatively single in variety, mostly emulsifiable concentrates, and water-dispersible granules in addition. Because the emulsifiable concentrate contains organic solvents (such as toluene, xylene, etc.), it is flammable, easy to leak, po...
