Butralin nano emulsion and preparation method thereof

Номер: CN102960337A
Автор: Chen Xingjiang, Liu Yong, Shang Shenghua, Cao Yi, Cai Liuti, Lu Ning
Принадлежит:

The invention discloses a butralin nano emulsion. The formula of the butralin nano emulsion comprises 25 to 70 percent of butralin oil phase, 0.6 to 2.4 percent of polyvinyl alcohol water phase and 0.1 to 1 percent of stabilizing agent, wherein the volume ratio of the butralin oil phase to the polyvinyl alcohol water phase is (1:1)-(1:9) and the butralin oil phase comprises 0.1 to 2 percent of emulsifier. The preparation operation is simple; an oil-in-water nano emulsion system is constructed by an ultrasonic treatment method; a butralin oil drop has a small particle size; under relatively low application concentration, an efficient and long-lasting effect of suppressing tobacco axillary bud germination can be achieved; and the safety of a application workers is protected, the dosage amount is reduced, and the environment is protected.

Принадлежит:

The invention discloses an abscisic acid nano-emulsion and a preparation method of the abscisic acid nano-emulsion. The abscisic acid nano-emulsion has the formulation: 25-70% of abscisic acid oil phase with the volume ratio of 1: 1-1: 9, 0.6-2.4% of polyvinyl alcohol water phase and 0.1-1% of stabilizer, wherein the abscisic acid oil phase contains 0.1-2% of emulsifying agent. The abscisic acid nano-emulsion is simple in preparation operation and capable of building an oil-in-water nano emulsion system by an ultrasonic treatment method; the obtained abscisic acid oil drops are small in particle size, even in particles and high in encapsulation rate; and the abscisic acid nano-emulsion effectively improves the stability of abscisic acid, an has slow release function, thus having higher application value.
