What is Piperonyl butoxide?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Piperonyl butoxide which has developed particularly rapidly in recent years. Do you know about Piperonyl butoxide?

The official answer: Piperonyl butoxide, abbreviated ENT -14250, is a colorless to light yellow oily transparent liquid. It has a slightly peculiar odor and bitter taste. Relative density 1.059, refractive index 1.50, flash point 171ºC (open cup). Easily discolored when exposed to light. Insoluble in water, miscible with methanol, ethanol, benzene, freon, grease, and other organic solvents. Acute oral LD50 11500mg/kg in rats, acute percutaneous LD50 1880mg/kg in rabbits, non-carcinogenic.

What’s the application of Piperonyl butoxide?

It is used as an insecticide to kill insects produced during the storage of rice, wheat, beans, and other grains, such as grain weevils. Often used in combination with pyrethrins to form complexes for synergistic effects. It is used as an insecticide synergist. It can improve the insecticidal activity of pyrethrins and various pyrethroids, rotenone, and carbamate insecticides.

The synergistic ether can improve the insecticidal activity of pyrethrins and various pyrethroids, rotenone, and carbamate insecticides, and also has a synergistic effect on fenitrothion, dichlorvos, chlordane, triclopyr, atrazine, etc., and can improve the stability of pyrethrum infusion. It has a higher synergistic effect on aminopyralid than octadecafluoro when it is used in housefly control; however, it cannot synergize cypermethrin in knockdown effect on houseflies. When used in mosquito coils, it has no synergistic effect on cypermethrin, and even its efficacy is reduced.

Efficacy and use: When pyrethrin 0.025g is contained in 100ml of refined kerosene alone, the mortality rate of house flies is only 19%, 32% when 0.050g is contained and 50% when 0.100g is contained, and the mortality rate of house flies can be as high as 85% when pyrethrin 0.025g + 0.25g of this product is contained in 100ml of kerosene. In the lice control test, when the preparation contains pyrethrin 0.005% and this product 0.05%, the mortality rate of body lice is 78%; if it contains pyrethrin 0.025% and this product 0.125%, the mortality rate of body lice can reach 100%, but in the treatment containing pyrethrin alone, the mortality rate of body lice is all 0. Using this product as a highly effective agent for controlling sanitary insects, warehouse pests, and horticultural pests as an insecticide, generally It is used 5 to 10 times as much as pyrethrins, which can increase the efficacy by 3 times, and the effect is remarkable. For example, in the storage of grain, use the mixture of this product (1:10) with cyhalothrin to control a variety of warehouse pests, and one application can protect the stored grain from pests for about one year. For agricultural pests such as cotton bollworms, this product is used in combination with cypermethrin, cyfluthrin, deltamethrin, and cyhalothrin respectively, and the efficiency index reaches 230, 167, 80, and 65.7, which is also very significant.

Toxicity of synergistic ether: acute oral LD50 for rats and rabbits >7.5g/kg; acute percutaneous LD50 for rabbits is 1.88g/kg, acute percutaneous LD50 for rats >7950mg/kg, no irritation to skin and eyes, no sensitizing effect on the skin. Acute inhalation LC50 for rats >5.9mg/L. No effect dose in feeding test: 30mg/kg BW-d for rats and mice (2 years), 16mg/kg BW-d for dogs (1 year). ADI for human is 0.2mg/kg bw. No teratogenicity, no mutagenicity, no carcinogenicity. No harmful effects were observed in rats fed with feed containing 10g/kg of this product per day for 3 generations. It is not toxic to fish and bees. The acute oral LD50 for quail was >2250mg/kg. carp LC50(24h) was 5.3mg/L. honeybee LD50 was >25μg/bee. Daphnia LC50(24h) 2.95mg/L.

WHY THEY SAY TO US

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
