Problems solved by technology

In the past, people have been using artificially synthesized BHA, BHT, TBHQ, etc. These artificially synthesized chemical substances can achieve certain effects, but at the same time they also bring certain side effects, which have irreversible damage to human liver and kidney, such as : Japanese experiments found that BHA has carcinogenic effect on the vestibule of rats. French scholars found that long-term consumption of BHT-containing food can cause liver enlargement. Therefore, Japan, the United States and other developed countries have limited or banned the use of artificial synthetic stabilizer

Embodiment 1

[0009] Add 0.2% rosemary extract (existing product) of active pyrethrin content to the natural pyrethrin raw medicine, mix thoroughly and evenly, and prepare the pyrethrin raw medicine that resists oxidation decomposition and light decomposition.

Embodiment 2

[0011] When preparing natural pyrethrin cream preparation, add 5% rosemary extract with pyrethrin active ingredient content, then add tangerine oil (Tangerine Oil) with pyrethrin active ingredient content 15% (main component is limonene), and then use turpentine oil Dilute and mix evenly to make a natural pyrethrin emulsifiable oil preparation containing 0.5-5% of pyrethrin active ingredients to resist oxidation decomposition and light decomposition.

Embodiment 3

[0013] When preparing wettable powder of natural pyrethrins, add 10% rosemary extract with active content of pyrethrins, mix well, then add dispersant with active content of pyrethrins at 10% (product name is emulsifier 5202) and 10% Wetting agent (ammonium alkylbenzene sulfonate), then add tangerine oil with 3% content of active pyrethrins, and finally add an appropriate amount of filler (diatomaceous earth: calcium carbonate = 8:2) to make active pyrethrins The natural pyrethrin wettable powder with the content of 0.5-1.5% is anti-oxidative decomposition and anti-light decomposition.

Abstract

The invention provides an optically stable and oxidization stable pyrethrin product, wherein rosemary extract containing 0.2-10% of pyrethrin is charged into Pyrethrum carneum crude medicament, emulsion, powder, and are mixed homogeneously. The rosemary extract provided by the invention is extracted from the natural plant of rosemary, and causes no toxic and side effect to human body.

Description

technical field [0001] The invention relates to a light-stable and oxidation-stable pyrethrin product made from pure natural rosemary extracts (rosemary extracts) as a light stabilizer and an antioxidant. Background technique [0002] The photostability and oxidation stability of natural pyrethrins are a difficult problem in the world. In the past, people have been using artificially synthesized BHA, BHT, TBHQ, etc. These artificially synthesized chemical substances can achieve certain effects, but at the same time they also bring certain side effects, which have irreversible damage to human liver and kidney, such as : Japanese experiments found that BHA has carcinogenic effect on the vestibule of rats. French scholars found that long-term consumption of foods containing BHT can cause liver enlargement. stabilizer. Therefore seek a kind of safer, more effective pure natural stabilizer and just become a key point in the present pyrethrum development field. Contents of the...
