studies mainly involve two aspects. One is synthetic fatty acid polyoxyalkylene ester
phosphates, such as oleic acid, linoleic acid, and ricinoleic acid. Its derivatives can
be used in organophosphorus insecticides and bactericides of organophosphorus in
emulsifiable concentrates. The other is epoxidized vegetable oils. Several vegetable
oil epoxides are commonly used, including soybean oil, linseed oil, rapeseed oil,
and cottonseed oils. Arsenic epoxide has also been used as stabilizers in emulsifiable
concentrates.
Some vegetable oils can be used as synergists of insecticides. The synergistic
effect of sesame oil and deltamethrin on the control of cotton bollworm was studied,
the results showed that by mixing sesame oil and deltamethrin at 1:1 ratio, and the
amount of deltamethrin could be reduced by a half to achieve a similar effect as
straight deltamethrin. According to the analysis, the main synergistic mechanism is
that sesamin in sesame oil contains methylene dioxyphenyl group, which inhibits the
multifunctional oxidase in the worms [38]. Edible vegetable oil also can increase the
control of avermectin EC against Plutella xylostella, and cottonseed oil could be used
as a synergist of monocrotophos to prevent blind piles. Experimental results showed
obvious synergistic effects on pyrethrum ester, carbamate, and organophosphorus
agrochemicals [39].
9.3 Outlook
At present, the cosmetic market of vegetable oil is keeping growing. A large number
of new multifunctional cosmetics components are based on vegetable oils, and their
hydrogenation products and fatty acid esters are widely used in the cosmetics industry.
With the increasing market demand of people to “return to nature and advocate
green”, as well as the improvement of plant extraction and purification techniques,
the application of natural vegetable oils has gradually become a hot spot. At the same
time, with the improvement of cosmetic efficacy evaluation technology, people’s
understanding of skin metabolism process, as well as the integration of personal
care products industry, we believe there will be more and better oils and fats to be
used in cosmetics that will also give more new, unique and special functions and
characteristics to personal care products to bring people more beauty and happiness.
The world is facing problems of increasing population, deteriorating environment, food and energy resources shortage. Agrochemicals play a pivotal role in
food production. But petroleum-based agrochemicals and their additives as chemical substances not only need to consume energy, but also pose a great threat to our
environment. Oils and fat have the advantages of being environmentally friendly,
biodegradable, strong affinity with targets, readily available, relatively low cost, and
using less dosage of additives when processed, which should be widely promoted in
the processing and use of agrochemicals.
