Test design of fixed dispersed oil suspension formulation mesotrione TC (15%), OF-3472 (3%) dispersing agent and synergistic agent: 6300 (3%), MF-33 (2%), stabilizer, thickener, emulsifier SK04 (1.5%): OF-3468.
Test design of fixed dispersed oil suspension formulation mesotrione TC (15%), OF-3472 (3%) dispersant and emulsifier OF-3468 (20%): 6300 (3%) synergistic agent, thickening agent SK04 (1.5%), a MF-33 (Jiangsu Haian chemical stabilizer), acetic acid (lactic acid (commercially available).
The suitable synergistic agent can make the product have good development and permeability.
In this work, 4A zeolite ([Na.sub.2]O[Al.sub.2] [O.sub.3]x2Si[O.sub.2]x9/2[H.sub.2]O) is chosen as a synergistic agent, which is cheap but has commercial significance.
In order to improve the flame retardancy of materials, various kinds of synergistic agents have been used in the IFR system to reinforce the flame retardancy, such as zeolites, expandable graphite, organoboron siloxane, and some transitional metal oxides, metal chelates, and metal compounds [17-24].
Piperonyl butoxide (PBO) is the synergistic agent most used industrially (ROCHA & MING, 1999) and had been in commercial formulations of several synthetic pyrethroid insecticides for many years (FARNHAM, 1998).
After an investigation in the health risks of ITX following the incident, the European Food Safety Authority (EFSA) concluded that the levels of it found in foods, "while undesirable, does not give cause for health concern." It also came to a similar conclusion about another photoinitiator, 2-ethylhexyl-4-dimethylaminobenzoate (EHDAB), which is used as a synergistic agent with ITX and was included in the inquiry.
It can be seen that the curves of HTTA and HP vary practically in the same manner as those including a synergistic agent. In addition, the heavier lanthanoids are extracted more effectively with a binary mixture HTTA-PAR than with HP alone although HTTA is a weaker acid than 4-acylpyrazolones.
It is known that the major factor in synergism is an increase in the hydrophobic character of the extracted metal complex upon addition of the synergistic agent [26, 27].
Some synergistic agents such as poly(2-morpholiny1-4-pentaerythritol phosphate 1,3,5-triazine) (PMPT) (12), borocalcite (13), layered double hydroxides (14), nickel catalyst (15), natural zeolite (16), (17), mesoporous silica (18), hydroxy silicone oil (19), organic montmorillonite (0-MMT) (20), ultrafine full-vulcanized rubber powder (21) etc., were used in APP/PER system.
Thererfore, to solve this problem, an effective route is the incorporations of some HFFR synergistic agents with MH.
MH combined with some HFFR synergistic agents, such as red phosphorous (RP), expandable graphite (EG), etc., could improve flame retardancy of MH and decrease its loading level.
