preparation example Construction

[0010] Preparation of chara mosquito repellent air freshening slow-release agent:

[0011] Raw material formula: chara essential oil 15%-20%, sodium percarbonate 5%-10%, Tween 60 or Tween 80 1%-5%, super absorbent resin (SAP) 2%-5%, sodium benzoate 0.5%-1%, appropriate amount of spices, and the rest is pure water.

[0012] The preparation method comprises the following steps:

Embodiment 1

[0014] Select fresh charophytes, wash them to remove impurities, dry them in the shade at room temperature and grind them; firstly mix the water and the prepared charophyta powder according to the ratio of 10:1, and then extract the semi-finished charophyta essential oil from them by steam distillation. The vapor pressure of the steam distillation is 0.05Mpa, and the distillation time is 1 hour; the prepared semi-finished Chara essential oil is concentrated under reduced pressure to obtain the required Chara essential oil; add the chara essential oil prepared in the steps into purified water, and stir Add Tween 60 and mix thoroughly; add superabsorbent resin to the prepared liquid to form a gel system, then add sodium percarbonate, and finally add sodium benzoate and spices, and mix well to form a gel liquid, that is, the wheel Algae Mosquito Repellent Slow Release.

[0015] In this example, the mass percentage of each raw material is: 15% of Charophyll essential oil, 5% of so...

Embodiment 2

[0019] Select fresh charophytes, wash them to remove impurities, dry them in the shade at room temperature and grind them; firstly mix the water and the prepared charophyta powder according to the ratio of 10:1, and then extract the semi-finished charophyta essential oil from them by steam distillation. The vapor pressure of steam distillation is 0.25Mpa, and the distillation time is 2 hours; the prepared semi-finished Chara essential oil is concentrated under reduced pressure to obtain the required Chara essential oil; add the prepared Chara essential oil into purified water and stir Add Tween 60 and mix thoroughly; add superabsorbent resin to the prepared liquid to form a gel system, then add sodium percarbonate, and finally add sodium benzoate and spices, and mix well to form a gel liquid, that is, the wheel Algae Mosquito Repellent Slow Release.

[0020] In this example, the mass percentage of each raw material is: 18% of Charophyll essential oil, 8% of sodium percarbonate...

Description

technical field [0001] The invention relates to a series of air freshening products for repelling mosquitoes from chara, in particular to an air freshening slow-release agent with mosquito repelling effect made by using the essential oil of the lower algae plant chara as the main active ingredient. Background technique [0002] The main ingredient used in air fresheners currently on the market is o-dichlorobenzene, which is the main ingredient in mothballs. Related reports have shown that o-dichlorobenzene can weaken lung function and affect the respiratory system. Moreover, most of the current air freshening products do not have the effect of repelling mosquitoes. Even if there are products with this effect, the main components of the mosquito repellent and antibacterial are mostly pyrethrins and other chemically synthesized products, and relevant reports show that pyrethrum Ester compounds can cause poisonous effects on fish, and long-term use is also harmful to human heal...
