The present invention relates to a liquid detergent composition, and more particularly includes a hydroxyethyl cellulose (Hydroxyethyl cellulose) to maintain a viscosity of 100 cps or more without precipitation caused by the reaction with a cationic surfactant And a liquid detergent composition having excellent cleaning power.

Liquid detergents are surfactants and other auxiliaries, which consist of polymers, solvents, metal ion encapsulants, scents, fuels, pH adjusters, etc. The polymers used in conventional liquid detergents are mostly anionic and settle by reacting with cationic surfactants with excellent sterilizing power. Therefore, there is a disadvantage in that the cationic surfactant and the polymer cannot be used together. In addition, it is not convenient to use as a liquid detergent when the diluted detergent is used because it does not maintain the viscosity of 100 cps or more, and the amount of cleaning agent must be used, and the amount necessary for cleaning cannot be properly adjusted. Many problems arise.

In order to solve the conventional problems, the present inventors invented a liquid detergent composition having excellent viscosity and detergency.

An object of the present invention is to maintain a viscosity of 100 cps or more using a hydroxyethyl cellulose polymer that does not react with a cationic surfactant having excellent sterilizing power, and the viscosity and detergency that can be diluted 10 to 100 times depending on the purpose of use To provide a good liquid detergent composition.

Methylene phosphoric acid is selected from the group consisting of salts with 1 to 8 substituted sodium.

The fragrance uses a lavender flavor, apple flavor, green tea flavor, pine oil.

[Experimental example]: Experimental evaluation of physical properties of the liquid detergent of Examples and Comparative Examples

The physical properties of the liquid cleaners prepared in Examples 1 to 5 and Comparative Examples 1 to 3 were carried out as follows, and the results are shown in Table 2.

* Phase stability evaluation: After leaving the liquid detergent at 20 ° C. for 1 day, the phase separation or precipitation phenomenon was visually observed. If there is no phase separation or precipitation, O is indicated. If phase separation or precipitation occurs, it is indicated by X. Table 2 Indicated.

* Viscosity evaluation: The liquid detergent was left to stand at 20 degreeC for 1 day, and it evaluated by the viscometer (manufacturer: Brookfield, model name: DV-1 + Viscometer).

* Evaluation of bactericidal power: E. coli as a bacterium and black mold (A. niger) as a mold were precultured as a test strain, and then a 106 CFU / ml bacterial suspension was prepared. The bacterial suspension was added 100 times diluted with 0.8% saline, and the bacterial count was observed after 10 minutes.

* Evaluation of cleaning power: 10 kinds of fatty acids are reacted with calcium and magnesium at high temperature to make the pollutants evenly coated on tiles 30cm wide and 30cm long to make pollutants. After soaking for 5 minutes, push and pull back and forth while pressing with a weight of 500g and wash with water. Observe the degree of decontamination visually. If the degree of decontamination is 90% or more, 5 points, 80% or more 4 points, 70% or more 2 points, 60% or more, 1 point was less than 60%. Table 2 shows the average values of 10 such repeated experiments. If it is 4 or more, it can be seen that washing | cleaning power is excellent.

* Ease of use after dilution: After diluting 50 to 100 times of liquid cleanser to 50 expert evaluators, evaluate the ease of use, and if it is inconvenient to use as a cleanser, use one point as a cleanser. In the case of convenience, the average value after giving 5 points is shown in Table 2, and more than 3.6 points can be seen as good.

As shown in Table 2, in Examples 1 to 5, no sediment was generated, so that the phase stability was excellent, the viscosity was maintained at 100 cps or more, and the sterilizing power and the cleaning power of the liquid detergent diluted 100-fold were also excellent, and 50-fold dilution Ease of use after dilution with one liquid detergent was good, above 3.7.

On the contrary, in Comparative Example 1, in which the cationic surfactant having excellent sterilization power was not added, it was excellent in phase stability, viscosity, detergency, and ease of use, but showed very low sterilization power, and is widely used as a conventional viscosity increasing agent. In Comparative Example 2 to which (Cabopol) was added, phase separation due to precipitates was observed, and Comparative Example 3, in which hydroxyethyl cellulose was not added, showed little discomfort and was very inconvenient when diluted.

As shown in the results of the above examples, the present invention comprising hydroxyethyl cellulose (Hydroxyethyl Cellulose) as a viscosity enhancer is easy to use as a liquid detergent even after dilution due to its excellent viscosity, and excellent sterilizing power Can be used with active agents.
