Preferably the detergent composition comprises further at least one kind of alcohol-based solvent selected from the group consisting of ethanol, isopropanol, isobutanol, propylene glycol and ethylene glycol, or at least one kind of organic acid selected from the group consisting of benzoic acid, salicylic acid and sorbic acid.

Description

Kitchen detergent composition with citronella oil or citral

The present invention relates to a dish detergent composition. More particularly, the present invention relates to a dish detergent composition containing natural citronella oil and citral derived from natural lemongrass and having a pH of 4 to 8, and a dish detergent and an antimicrobial agent. In addition, it can avoid the hassle of using deodorant, and it has deodorant effect to remove antibacterial and bad odor and deodorant effect at the same time.

Tableware, dishcloth, and scrubbers used in the kitchen breed many kinds of germs through food waste or moisture, causing unpleasant odors, and frequently causing skin eczema on the hands by frequent washing dishes and food waste.

In particular, odors such as fish, meat, water fishy (amine odor) and kimchi (mercaptan odor) are difficult to remove with general dish detergent, and ammonia due to debris hanging in the drain of sink and bacteria Odor substances containing, amines, mercaptans and the like cause an unpleasant odor.

Conventionally, general detergents and special products for disinfecting and disinfecting are removed to remove them, and the unpleasant odor is mainly ventilated or a dedicated deodorant is used. In addition, the conventional antimicrobial products are mainly made of synthetic raw materials, but the degree of difference depending on the individual, but may exhibit various side effects such as skin spots, allergies.

Japanese Patent Documents JP92-298513 and JP90-217064 describe general deodorant compositions using green tea extracts and polyols, JP96-281042 describes carbonized bamboo powders, and US 4,906,462 deodorants using phosphoric acid and derivatives thereof. It describes.

For general sterilization and antimicrobial agents, ethanol, p-dichlorobenzene, chlorine compounds (lacx), benzalkonium chloride (benzalkonium chloride), etc. are mainly used. Deodorant preparations are mainly extracted from green tea and bamboo. I'm using them.

Conventional dishwashing agents mainly have a cleaning function or have a sterilization concept containing a synthetic disinfectant, but have little effect on deodorization. In addition, if the existing deodorant contains a content enough to have the effect in the dishwashing detergent, the price of the extract is difficult to apply, and also affects the stability in the product.

In addition, the compounds of p-dichlorobenzene, chlorine compounds (laxes) and benzalkonium chloride (benzalkonium chloride) are the main active ingredients in dishwashing agents, which are anionic surfactants. Decreases the function of or causes severe skin irritation.

Accordingly, the technical problem to be achieved by the present invention is to contain citricella oil or natural citrusella derived from natural lemongrass in a conventional detergent to solve the problems as described above more efficiently, breeding in the kitchen hygiene To effectively remove E. coli, food poisoning bacteria, bacterial dysentery, Salmonella, etc., which can harm the smell, and to remove the unpleasant odors such as dishware, dishcloth, loofah, cutting board, etc. Reached.

In order to achieve the above object, the present invention contains at least one active ingredient selected from citronella oil and citrus derived from lemongrass, while containing a surfactant and a solvent, the content of the active ingredient is total It is to provide a kitchen detergent composition that is 0.01 to 10% by weight of the weight.

Citronella oil, which is an active ingredient as a kitchen detergent composition of the present invention, extracts dried leaves of a monocotyledonous plant native to Sri Lanka, Southeast Asia, South America, etc. through steam distillation, and is used as a pest control agent because moles and mosquitoes do not like it. It acts as an excellent sterilization and antiseptic and is used as a deodorant by absorbing odor because of its high absorption power such as trimethylamine, ammonia and mercaptan.

In addition, light and fresh scent to stabilize the nerves, headaches, migraines, neuralgia, depression is also used as a direction therapy to relieve a lot.

Citronella oil in the detergent composition of the present invention is preferably contained in 0.01 to 10% by weight. When the content of citronella oil in the detergent composition is 0.01 or less, the sterilization deodorizing power is lowered, and when the content of the citronella oil is 10% by weight or more, the viscosity increases, the cleaning power and the foaming power are lowered, and the stability of the phase is lowered.

In addition, citral derived from natural lemongrass in the dishwashing agent composition of the present invention serves to mask unpleasant odor in a fresh direction with excellent bactericidal power against bacteria, the structure of which is represented by the following formula (1).

In the detergent composition of the present invention, citral is preferably contained in an amount of 0.01 to 10% by weight. When the content of citral in the detergent is 0.01% by weight or less, the sterilization deodorizing power is lowered, and when it is 10% by weight or more, there is a problem that the cleaning power and the foaming power are lowered.

In addition, the detergent composition of the present invention deodorizes the mercaptan generated in the sink and drain by additionally using an alcohol solvent such as ethanol, isopropanol, isobutanol, propylene glycol, ethylene glycol, or a mixture thereof as a sterilizing and deodorizing aid. And a bactericidal effect, and by using benzoic acid, salicylic acid, or sorbic acid as an organic acid, the bactericidal and deodorizing effect may be simultaneously exhibited.

The formulation of the detergent composition of the present invention is not particularly limited, but is preferably in the form of a liquid, a solid phase, or a gel, and the amount of use may be in accordance with a conventional amount of detergent.

The detergent composition according to the present invention preferably has a pH of 4-8 at room temperature, more preferably 5-7.

Hereinafter will be described based on Examples and Comparative Examples of the present invention, but these do not limit the technical scope of the present invention.

Among the representative bacteria that can be produced in a residential environment, a bacterial solution diluted (2.0 x 10 ⁶ / ml) of E. coli ATCC 8739, Staphylococcus aureus (S. Aureus ATCC 6538) and Pseudomonas ATCC 15522 After contaminating the test cloth (white cotton cloth sterilized at 105 ℃ for 1 hour or more) in the inside, after washing for 1 minute with the compositions of Examples and Comparative Examples, rinsed clean, placed on the bacterial culture medium and cultured bacteria at 37 ℃ to increase the degree of growth Measure

Evaluation of dish towel sterilization

◎: complete sterilization O: sterilization △: suppression X: growth

2) Sterilization Evaluation Method

Salmonella (Salmonella typhi ATCC 19430) and dysentery (Shigella flexneri ATCC 9199) are supported and evaluated after standing at 40 ° C for 24 hours.

Evaluation of bactericidal power

◎: complete sterilization O: sterilization △: suppression X: growth

3) Deodorizing force test method

Put the composition of Example and Comparative Example in a sealed container and put the same amount of three kinds of odor source, respectively, and after a certain time, the residual amount of odor which has not been deodorized is sucked into the detection tube to measure the concentration of residual gas. (Using Gas Decter detector)

① Ammonia: Use ammonia detector, 0.5ml of 0.03% aqueous solution

② Amine: Use ammonia detector, 0.5ml of 0.03% aqueous solution

③ Mercaptan: Using ammonia detector, 0.5ml of 0.03% aqueous solution

Determination of Deodorizing Power : Evaluation by Detection Concentration of Detector

-80ppm or more: No deodorizing power (X)

-50 ~ 80ppm: Minor deodorizing power (△)
