Description

gel cleanser composition

The present invention relates to a gel-like detergent composition used on hard surfaces such as toilet bowls, glass, windows, doors, and bathroom walls.

Conventionally, various detergents have been used to create a hygienic environment by removing dirt adhering to hard surfaces such as toilet bowls. For example, as a cleaning agent for a flush toilet, an on-tank or water tank designed to dissolve the cleaning agent into the flush water (flush water) is used by being installed in the hand washing part or the water storage tank of the flush toilet. Toilet detergent for in-tank use. However, in recent years, flush toilets without a tank have been popularized, and there is a disadvantage that toilet detergents for use on or in the tank cannot be applied to flush toilets without a tank.

On the other hand, there is known a toilet cleanser for a rim, which is installed on the rim of a toilet bowl and allows the cleanser to flow out into flushing water flowing into the toilet bowl. The toilet cleaner for the rim part can be applied to a flush toilet without a tank, but it has disadvantages in terms of sanitation, such as dismantling the rim part before and after use, so it is not widely used at present.

Therefore, in recent years, a gel-like cleanser that is attached to the surface of the toilet bowl and used has been developed. For example, in Patent Document 1, it is reported that a toilet made of a polyoxyethylene alkyl ether composed of a polyoxyethylene group having a degree of polymerization of 13 to 50 and an alkyl group having 12 to 18 carbons The gel-like detergent is attached to the surface of the toilet bowl, and even if it comes into contact with running water, it can maintain the attached state of the toilet bowl surface, and in this state, the detergent is continuously released into the running water. In addition, Patent Document 2 discloses that a gel-like detergent containing a specific polyoxyalkylene block polymer suppresses liquefaction and maintains its properties stably even under high-temperature conditions.

On the other hand, in order to maintain the hard surfaces of toilets and other toilets in a hygienic state, it is necessary not only to clean the dirt, but also to remove miscellaneous bacteria or inhibit the formation of biofilm by sterilization. The formulation of antibacterial components is effective for removing miscellaneous bacteria and inhibiting biofilm formation, but conventionally, sufficient research has not been conducted on gel-like detergents in which anti-bacterial components are formulated.

In addition, the present inventors found that by combining polyoxyethylene polyoxypropylene block polymers (polyoxyethylene polyoxypropylene block polymers) selected from polyoxyalkylene alkyl ethers, specific structures, And at least one of the group consisting of water-soluble inorganic chlorides and benzalkonium chloride and polyoxyethylene polyoxypropylene block polymers with specific structures are formulated to produce gel-like detergent composition The adhesion of the gel-like detergent composition to the hard surface also becomes good.

Furthermore, the present inventors found that by combining polyoxyalkylene alkyl ether with water-soluble inorganic chloride or combining water-soluble inorganic chloride with amphoteric surfactant, benzalkonium chloride and specific structure of poly Oxyethylene polyoxypropylene block polymers are formulated together to produce a gel-like detergent composition, which can stably form a gel state even after storage at high temperature.

Hereinafter, although an Example is given and demonstrated to this invention, this invention is not limited to these Examples. Furthermore, in the following examples, ethylene oxide is sometimes abbreviated as EO, propylene oxide is abbreviated as PO, and butylene oxide is abbreviated as BO.

Test example 1 (1) Preparation of detergent composition A detergent composition (in 50 g in a container). In addition, the abbreviation of each component shown in Table 1 and Table 2 is as follows. In addition, the content shown in Table 1 and Table 2 represents the substantial amount of each component except the solvent contained in the added additive (commercial product).

(2) Determination of gel strength Gel strength was measured using a rheometer CR500DX (manufactured by Sun Science Co., Ltd.) with a pressure sensitive shaft having a diameter of 10 mm at 25° C. and a shear rate of 60 mm/min (mode 20). Regarding the measured gel strength, the gel strength was judged according to the following judgment criteria. Furthermore, if the gel strength is 50 gf or more, it can be said that the gel-like detergent composition attached to the hard surface has moderate gel strength, and if the gel strength is 80 gf or more, it can be It can be said that it has moderate gel strength as a gel-like detergent composition that adheres to hard surfaces, and if the gel strength is 100 gf or more, it can be said that it has a gel-like detergent composition that adheres to hard surfaces. Particularly moderate gel strength. (Criteria for judging gel strength) ⊚: The gel strength is 100 gf or more. ◯: The gel strength is 80 gf or more and less than 100 gf. Δ: The gel strength is 50 gf or more and less than 80 gf. ×: The gel strength is less than 50 gf, or the gel strength cannot be measured due to liquefaction.

(3) Evaluation of adhesion to hard surfaces 3.5 g of each detergent composition was filled in a container of "BLUELET DECORAL" (Kobayashi Pharmaceutical Co., Ltd.), and placed on the surface of the bowl of toilet C730 manufactured by TOTO Corporation, so as to have 5 pieces Apply in a petal-shaped shape from the center to the outermost edge of about 20 mm. Immediately after the application, rinsing was performed continuously 50 times using a water tank S731B manufactured by TOTO Corporation, and the state of the detergent composition on the surface of the bedpan was observed. (Criteria for judging the adhesion to hard surfaces) ⊚: Even if the number of times of flushing was 50, it did not peel off from the bedpan and adhered stably. ◯: Does not peel off from the bedpan until the number of times of flushing is 9 times, but peels off from the bedpan after the number of times of flushing is 50 times. △: Does not peel off from the bedpan when the number of times of flushing is 3, but peels off from the bedpan after the number of times of flushing is 9. ×: Peeled off from the bedpan until the number of times of flushing was 3 times.

Δ: Significant softening or hardening was confirmed, and a change in the gel state was confirmed. ×: Liquefied or too hard to take out from the container.

The appearance of the obtained detergent composition was observed, and the transparency was evaluated according to the following criteria. (Criteria for judging transparency) ○: Transparent. Δ: Slightly cloudy. X: Clearly cloudy.

In addition, in addition to benzalkonium chloride and EO-PO block polymers, polyoxyethylene cetyl ether, EO-BO-PO block polymers, and water-soluble inorganic chlorides ( In the case of at least one of ammonium chloride and sodium chloride), the adhesion to hard surfaces was also good (Example 3 to Example 10). Furthermore, when polyoxyethylene cetyl ether and water-soluble inorganic chlorides (ammonium chloride, sodium chloride) are contained in addition to benzalkonium chloride and EO-PO block polymer , can stably form a gel state even after high-temperature storage (Example 5). In addition, in addition to benzalkonium chloride and EO-PO block polymers, water-soluble inorganic chlorides (ammonium chloride, sodium chloride) and amphoteric surfactants are included, even after high-temperature storage A gel state was also formed stably (Example 6).
