Problems solved by technology

[0005] 1) The effect of removing heavy dirt in the kitchen is not good;
[0006] 2) Alkaline is too strong, easy to hurt hands;
[0007] 3) Product ingredients contain refractory substances, causing environmental problems
Tea tree essential oil is non-toxic, fresh, and has antibacterial and anti-virus effects and strong decontamination and degreasing ability. However, due to its high price, it is only used in toothpaste and cosmetics at present. If it is used in detergents, the cost will increase dramatically. so difficult to use in practice
[0010] In addition, U.S. Patent US2006 / 0241011A1 also proposes to use fluorine-containing nonionic surfactants, amine oxides or anionic surfactants for compounding, and obtains a high oil stain removal effect, but the cost is relatively high
In addition, although some detergent compositions contain a large amount of surfactants and lemon essential oil, the compatibility between the components is poor, and phase separation is prone to occur, resulting in white turbidity and it is difficult to achieve a satisfactory and uniform cleaning effect.
[0011] In summary, although there are many products that can effectively remove animal and vegetable oils, they cannot provide a cost-competitive cleaner that can solve the above three problems at the same time
As a comprehensive solution, the cleaning agent should be phosphorus-free, low VOC, reasonable alkaline level and low cost, however, it is quite difficult to obtain such degreasing agent that can effectively remove oil stains, is safe and environmentally friendly, and is inexpensive

Embodiment

[0140] The source of the raw material that adopts in the embodiment is as follows:

[0141] Berol 226, cationic surfactant, purchased from Akzol Nobel company;

[0142]D-limonene (D-limonene) was purchased from Florida chemical company.

[0143] Orange terpene was purchased from Florida chemical company.

[0144] 23E7, fatty alcohol polyoxyethylene ether with 12 to 16 carbon chains of 7 EOs, purchased from Sasol;

[0145] Lauryl dimethyl amine oxide is available from Sasol;

test approach 1

[0147] Test method 1: detergency test test

[0148] Prepare with the ratio of tallow: lard: vegetable oil=0.5:0.5:1, and add glyceryl monostearate accounting for 5% of the total mass to prepare artificial oil stain. Among them, the butter is bright butter purchased in supermarkets, the lard is refined, and the vegetable oil is arowana. Put the artificial oil in a beaker and heat it on an electric furnace at 180°C, stir to maintain this temperature for 10 minutes, and cool it naturally to the required temperature of 80°C for later use. At this time, the room temperature is 20°C.

[0149] Prepare a clean 75mm×26mm×2mm microscope glass slide, weigh it, and record it as M0.

[0150] Immerse the slide glass in the oil, take it out after 1-2 seconds, let the slide slide dry at room temperature for 12 hours, weigh it accurately with an analytical balance, and record it as M1.

[0151] Prepare a mechanical stirrer and a 300ml glass beaker. Pour 200ml of the test solution into the b...

[0160] Test Method 2: Skin Irritation Test

[0161] The cleanser composition was dropped on one side of a four-ply gauze measuring 2.5 cm x 2.5 cm and applied to the skin. The application time is 4 hours. After the test, remove the residual detergent composition with warm water or a non-irritating solvent. Observe the degree of skin irritation reaction 1h after removing the cleanser composition, and carry out the skin irritation reaction integral and stimulation intensity evaluation according to Table 1 and Table 2.

Abstract

The invention relates to a cleanser combination which contains cationic surfactant and citrus essential oil constituent, which relates to a method using the combination to remove dirt from the surface of basic material. The cleanser combination includes: (a) cationic surfactant, the weight of which is 0.5-30 percent of the combination; (b) citrus essential oil, the weight of which is 0.01-5 percent of the combination; (c) equilibrium amount of carrier.

Description

technical field [0001] The present invention relates to cleaning compositions, and more particularly to cleaning compositions comprising a cationic surfactant and a citrus essential oil component, and to methods of using such compositions to remove soil from substrate surfaces, especially hard surfaces. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for housing are no longer satisfied with simple living functions, but they are paying more and more attention to the beauty, cleanliness and hygiene of the environment. As a very important aspect of the modern home environment, restaurants and kitchens have increasingly become important indicators for people to measure and judge food safety, living standards and tastes by the health and sanitation of their surrounding environments. Therefore, people pay more and more attention to the sanitation of restaurants, kitchens and their surrounding environments, mainly fo...
