Long-acting mosquito repellent laundry detergent and preparation method thereof

Abstract

The invention belongs to the technical field of daily chemical cleaning products, and particularly relates to a long-acting mosquito repellent laundry detergent and a preparation method thereof. The long-acting mosquito repellent laundry detergent is prepared from the following raw materials in percentage by weight: 5.0%-30.0% of an anionic surfactant, 1.5%-40.0% of a nonionic surfactant, 5.0%-10.0% of a p-menthane-3,8-diol capsule microemulsion, 4.0%-10.0% of a suspension stabilizer, 0.02%-0.7% of a builder and the balance of water, wherein the suspension stabilizer is a composition of an acrylate copolymer, carboxymethyl cellulose and guar gum hydroxypropyl trimethyl ammonium chloride. The obtained long-acting mosquito repellent laundry detergent has the characteristics of strong decontamination, long-acting mosquito repelling, safety and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of daily chemical cleaning products, in particular to a long-acting mosquito repelling laundry liquid and a preparation method thereof. Background technique [0002] Practical experience tells us that fabrics treated with insect repellent are effective in preventing mosquito bites and are widely recommended by the WHO as a way to combat mosquito-borne diseases. Based on this, the laundry detergent obtained by adding the mosquito repellent with mosquito repellent effect can not only clean and decontaminate, but also make the treated fabric achieve the mosquito repellent effect. [0003] However, existing mosquito repellents for use in laundry detergent or fabric care compositions suffer from the following problems: [0004] 1. Commonly used mosquito repellents mostly use pyrethroids as active ingredients. Pyrethrins have the effect of knocking down, killing and repelling mosquitoes, but pyrethroids will caus...

AI Technical Summary

Problems solved by technology

However, pyrethroid insecticides belong to the category of pesticides, which are strictly controlled by the state, and pyrethroid insecticides are harmful to the human body, so they are not suitable for fabric washing

[0005] 2. Traditional natural plant mosquito repellants mostly use natural plant extracts such as citronella oil or lemon eucalyptus oil. Although they are safe and environmentally friendly, their smell is relatively irritating, which affects consumers' experience in use, and the washability is not good. The effective ingredients of mosquito repellent are easy to be lost with washing, and the long-term mosquito repellent effect cannot be achieved

For example, the invention CN201810314272.7 provides a mosquito repellent laundry detergent. The main components of the mosquito repellent are traditional vanilla essential oil, mugwort essential oil, geranium essential oil, camphor essential oil, and citrus essential oil. The mosquito repellent ingredients are directly added to the laundry detergent A certain mosquito repellent effect can be achieved in the liquid, but the smell of the obtained mosquito repellent laundry detergent is more irritating

[0006] 3. Natural mentediol mosquito repellent is insoluble in water, and it is difficult to make a high-concentration aqueous solution, so it cannot be directly applied to liquid laundry detergent or fabric care composition

For example, the invention CN201510419999.8 provides an anti-mite fabric care composition and its use method, which discloses that montanediol is used as an anti-mite agent in the anti-mite fabric care composition, which has an anti-mite effect, but its There is no mention of the application of mengdiol in laundry detergent and the mosquito repellent effect, and a large amount of solvents are needed to solubilize mengdiol

[0007] 4. The existing mentediol microcapsules are in the form of powder, and there will be a problem of poor suspension stability when used in laundry detergent

For example, the invention CN201811164903.8 provides a microcapsule slow-release mosquito repellent containing mentediol and 2-undecanone, which discloses a slow-release mosquito repellent made from microcapsules of mentediol and 2-undecanone The agent powder has the effect of mosquito repellent and sustained release, but it will have the problem of poor suspension stability when directly applied in laundry detergent
