Description

Liquid Toilet Bowl Cleaner Composition Containing Di-limonene

The present invention relates to a liquid toilet cleaner composition containing D-limonene for use in a toilet tank for the purpose of toilet bowl cleaning and for the purpose of deodorization that may come out of a toilet bowl.

More specifically, the present invention is used to put in a certain container and installed in a certain position of the toilet tank to use the toilet cleaning function, to provide a clean image coming from maintaining a uniform color as well as to remove the odor that can fly from the toilet bowl It relates to a liquid toilet bowl cleaning composition comprising a natural raw material D-limonene.

Solid toilet cleaners used in the prior art have limitations in the selection of a cleaning function material coming from a solid and imparting a clean image due to uneven color (for example, Korean Patent No. 8173, European Patent No. 0184416, (0055100, British Patents 1601123, 2021143, and 2061996). In addition, the conventional liquid toilet cleaner has been mainly used a low biodegradable surfactant containing petroleum-based synthetic surfactants and benzene with the main function of cleaning. In particular, even though the toilet cleaner contains a small amount of aroma in the existing technology, the cleanliness image due to the color impartment was not recognized at all because the toilet cleaner had no smell at all before and after the toilet.

As a type of general toilet cleaner, the first powerful cleaning product that is directly sprayed with a brush after spraying the cleaning agent, and the second product that is automatically cleaned by water supply after installing the cleaning product at a certain position of the toilet The present invention is classified into secondary cleaning products.

The liquid toilet bowl composition of the present invention is a hanger type automatic cleaner in a toilet bowl tank, which plays a role in cleaning the toilet bowl (howl or Lavoratory), and eliminates the inconvenience of using the toilet to directly remove the toilet contamination. Combining a clean image from the color after washing, it is possible to completely escape the preconceived notions of toilets that people have conventionally recognized.

The liquid toilet cleaner composition of the present invention may contain nonionic surfactants, solubilizers, phase stabilizers, dyes and D-limonene.

Since the liquid toilet cleaner composition of the present invention is a liquid containing natural D-limonene with excellent biodegradability, a surfactant, and a dye, it can maintain a uniform color to solve the conventional problem of poor biodegradability and uneven color coming from a solid. In addition, it contains D-limonene, which has a natural scent, to give a clean and visual image to the toilet after the toilet.

The present invention provides a liquid toilet bowl composition comprising 5 to 25 parts by weight of an alcoholic nonionic surfactant and 3 to 40 parts by weight of D-limonene.

In the present invention, the surfactant used for cleaning the toilet bowl includes an ionic surfactant and a nonionic surfactant, but since the present invention is an acidic base, a weak ionic surfactant is not suitable for an acidic base and an alcoholic nonionic surfactant is used. Suitable. The amount of the alcohol-based nonionic surfactant is preferably 5 to 25 parts by weight, and when used at 5 parts by weight or less, a true cleaning effect cannot be expected, and even when used at 25 parts by weight or more, a large amount of air bubbles are generated, resulting in cleanliness after cleaning. The effect is sharply lowered.

In the present invention, the nonionic surfactant may be alcohol phenolic, fatty alcohol sorbitan fatty acid derivative, etc., in particular, alcoholic nonionic having 3 to 20 ethylene oxide addition moles to secondary alcohol having 10 to 16 carbon atoms. Surfactants are preferred.

D-limonene, which is used in the present invention, is a material extracted from an orange peel that is easily encountered at home, and has a strong cleaning function and aroma function. Recently, literature on the toxicity stability of D-limonene has been poured out (for example, Veterinery Clinics of North America; Small Auimal Parclice P 383 Vol. 20 No. 2 1990). (Japanese Patent No. 13, No. 12, May 63, 63, European Patent No. 0467660, Japanese Patent No. 61-238940). The chemical formula of this D-limonene is 1-methyl-4- (1-methylethenyl) sirolohexene, and the molecular formula is to be.

D-limonene, an oil-based formulation material, is used together with nonionic surfactants to enhance the cleaning function and to give a clean image. The amount of D-limonene is preferably 3 to 40 parts by weight, and when used at 3 parts by weight or less, the cleaning effect is excellent, but the fragrance effect is insignificant.

Strong acid is preferable for cleaning the toilet, but citric acid is avoided by using strong acid such as phosphoric acid, hydrochloric acid and sulfuric acid in terms of human health and environmental pollution, and the amount of use is preferably 0.1 to 10 parts by weight. If it is used at 0.1 parts by weight or less can not be expected a true cleaning effect, when used at more than 10 parts by weight is too strong acid.

Dye is used to show a clean image, the amount of use is preferably 1 to 20 parts by weight, the use of less than 1 part by weight of the clean image appears weak, when using more than 20 parts by weight maintain a too dark color rather reject The reaction appears.

The solid toilet cleaner used in the prior art has low biodegradability when used as a NP (polyphenylglycol ether) system in which EO (ethylene oxide) addition mole number is several tens or more due to the specificity coming from solid. Deodorization direction and uniform color can not be maintained.

The toilet bowl cleaning composition of the present invention exhibits excellent biodegradability, including derivative surfactants such as palms and palms derived from nature, fatty alcohol surfactants without benzene ring, and LAS (linear alkylbenzene sulfonate) and NP (poly). In the case of containing a benzene ring such as phenylglycol ether, it has an excellent cleaning effect but shows a very low biodegradability due to the benzene ring (see Comparative Example 3).

Fatty acid-based surfactants with excellent biodegradability are contained, but when the sample base is a strong acid, the SO (sulfonate functional group) of the bonding terminal group of the anionic surfactant is broken by the strong acid, thereby preventing the surfactant from functioning. Rather, phase separation occurs (see Comparative Example 4).

As described above, the liquid toilet cleaner composition according to the present invention provides a clean image due to maintaining uniform color while having excellent cleaning and fragrance performance and exhibits a great effect on water quality protection by using natural raw materials.

Hereinafter, the present invention will be described in more detail with reference to Examples.

×: Not uniform every time

※ Theoretical Evaluation Method of Direction Effect

15 households a day for four households per family

-1 use: 1g

-D-limonene content in 1g of product: 0.1g

-Toilet water tank usage: 10ℓ

-D-limonene concentration in one use: 0.1ℓ / 10ℓ → 10mg / ℓ → 10ppm

-Aroma concentration that can be felt by humans: 4ppm or more

(Slightly fluid depending on flavor type and other phase mix)

The evaluation results are shown in Table 2 below.

As can be seen from the above, the liquid toilet bowl composition according to the present invention has a cleaning, aroma, and deodorizing effect compared to the conventional solid toilet cleaner due to the non-ionic surfactant having excellent biodegradability and the acid-based liquid solution. It can be seen that the clean image imparting effect is large.
