Description

Viscous cleaning agent composition with sterilizing power

The present invention is a viscous liquid detergent composition having bactericidal power, more specifically, 3 to 10% by weight of nonionic surfactant, 5 to 15% by weight of alkali (earth) metal metasilicate, 1 to 5% by weight of alkanolamine It consists of a cleaning agent composition and a disinfectant composition containing 0.2 to 2% by weight of glutaraldehyde and / or quaternary ammonium salt that has a cleaning effect, and has an excellent cleaning effect and a sterilization function. It can be effectively used inside elevators, bathrooms, household cookware, industrial equipment, etc.

Conventional cleaning agents have been directly or indirectly damaged by the use of excessive surfactants, caustic soda, which is designated as phosphates and hazardous chemicals, methanol, isopropyl alcohol, etc., as solvents, in order to increase the cleaning effect. In addition, the washing power is the same, but is commercially available using a cellulose-based midpoint agent to represent a high concentration of the detergent. Such a detergent composition is difficult to manufacture, expensive to manufacture, there is a problem that the liquid is unstable long-term storage difficult.

The present invention is composed of a nonionic surfactant, an inorganic detergent, an alkanolamine, and a quaternary ammonium salt and / or glutaraldehyde having a bactericidal power, thereby having an excellent washing effect and a sterilizing function. In addition, it does not use caustic soda, phosphate, methanol and isopropyl alcohol, which is designated as a hazardous chemical substance, to provide an environmentally friendly cleaning composition.

The present invention is a viscous liquid detergent composition having a bactericidal power, more specifically 3 to 10% by weight of nonionic surfactant, 5 to 15% by weight of alkali (earth) metal metasilicate, 1 to 5% by weight of alkanolamine The present invention relates to a disinfectant composition comprising a detergent composition, a quaternary ammonium salt having a washing effect, and / or 0.2 to 2% by weight of glutaraldehyde and water.

The nonionic surfactant used in the present invention is 3 to 10% by weight, preferably 4 to 7% by weight, the structure is represented by the following formula (1).

[Formula 1]

R-Ph-O- (CH ₂ CH ₂ O) nH, (polyoxyethylenealkylphenyl ether)

In the above formula, R is an alkyl group having 8 to 10 carbon atoms, Ph is a phenyl group, and n has a form in which the added mole number of ethylene oxide is 8 to 15. If the content of the nonionic surfactant is less than 3% (hereinafter, by weight%), the washing power is low, and when the content of the nonionic surfactant is more than 10%, bubbles are excessively generated, and a large amount of water is required to remove it during use.

Alkaline (earth) metal metasilicate, which is an inorganic detergent, is used in an amount of 5 to 15%, preferably 7 to 12%, and the structural formula is represented by Chemical Formula 2.

[Formula 2]

M ₂ O. SiO ₂ nH ₂ O

In the formula, M is Na, Mg, Ca, Ba ions, n represents an integer.

(When n is 5, Pentahydrate is shown, and when n is 9, it shows Nonahydrate)

The use of alkali (soil) metal metasilicates increases the washing power and at the same time acts as a thickener, thereby eliminating the need to add a cellulose system or other thickeners separately. In addition, alkali (soil) metal metasilicate is used for rust preventive use of the cleansing agent, it can be useful because there is no corrosion when used in industrial equipment and the inside of the metal elevator.

Alkanolamine is used 1 to 5%, preferably 1 to 2% of alkanolamine, and the group formula is represented by the formula (3).

[Formula 3]

(HOCH ₂ CH ₂ ) _x NH _y

In the formula, x + y = 3, x represents 1 to 3, y represents 0 to 2. Namely mono-, di-, tri-ethanolamine. If the content of alkanolamine is less than 1%, the washing power is low, and if more than 5%, a lot of foam is generated.

A quaternary ammonium salt and / or glutaraldehyde used as a bactericide is used in an amount of 0.2 to 2%, preferably 0.7 to 1.5%, and the structural formula is represented by the formulas (4) to (6).

[Formula 4]

[Formula 5]

Wherein R 1 is an alkyl group having 8 to 14 carbon atoms, R 2 and R 3 are each an alkyl group having 1 or 2 carbon atoms, and [X] is two monovalent inorganic or organic anionic groups or one divalent inorganic or Organic anion group.

[Formula 6]

OHC (CH ₂ ) ₃ CHO

The quaternary ammonium salt and glutaraldehyde which have a bactericidal effect are used alone or in combination, respectively, 0.2 to 2%, preferably 0.7 to 1.5%.

The water content is 100% of the detergent composition, and the coloring and deodorant function (2,6-Di-t-Butyl-p-Cresol, BHT) are added.

Such detergent composition has an excellent cleaning effect and at the same time have a sterilization function can be effectively used in elevators, bathrooms, household cooking utensils, industrial equipment, etc., which require contamination and sterilization at the same time.

Hereinafter, the present invention has been described in detail with reference to Examples, but the present invention is not limited by Examples.

[Examples 2 to 4]

Next, a detergent composition was prepared in the same manner as in Example 1 with the content and composition as shown in Table 1, and the prepared detergent was compared with the commercially available detergent and the cleaning ability is shown in Table 2. In the present invention, in order to use the stainless steel sheet as a specimen, cut and polished to 2 × 10 cm and immersed in 5% caustic soda solution for 2 minutes to remove the alkaline solution with water and washed with ethanol and dried for 1 hour in 100 ℃ oven Cooled. Synthetic oil was evenly applied to the specimen with a roll coater and then weighed. The detergent composition prepared in Examples 1 to 4 was diluted 20 times with water, and the specimen was immersed and washed with ultrasonic waves for 5 minutes.

In addition, potato starch and water were well mixed in a 250 ml transparent glass bottle to measure the bactericidal effect, and left in an oven at 30-35 ° C. for 2 weeks to generate a fungal bacterium. Two weeks later, the fungus was confirmed to be formed, and the detergent composition prepared in Examples 1 to 4 was diluted 20 times with water, and 50 ml was placed in a transparent glass bottle. After 3 minutes, the presence or absence of bacteria was confirmed. Shown in
