Description

[0001] LIQUID DETERGENT COMPOSITION [0002]

The present invention relates to a liquid detergent composition used for a hair detergent such as a shampoo, a rinse-in shampoo, a body soap, a hand soap, a foam hand soap, a skin cleanser such as a cleansing foam, a kitchen detergent and a medical detergent.

The liquid detergent composition has low irritation to the skin and is expected to have a high sterilizing effect against pathogenic bacteria such as Escherichia coli as well as excellent foaming performance such as foam generation, creaming property of foam, and rinsing property. Conventionally, a fatty acid salt has been used as a cleaning component having excellent bubble performance and having a high sterilizing effect on pathogenic bacteria such as Escherichia coli. However, when the above-mentioned fatty acid salt is used in the liquid detergent composition, there is a problem that fatty acid is precipitated due to a decrease in pH, clogging of a mesh of a former container accompanied thereby, deterioration of rinsing property and skin irritation.

In order to solve the above problems, it has been proposed to improve the pH of a liquid detergent composition that causes precipitation by using a counter ion of a fatty acid salt, that is, a nitrogen compound for neutralizing fatty acids (see Patent Document 1). According to this proposal, although the pH stability of the liquid detergent composition is improved by using the salt of the alkanolamine of the fatty acid, it is insufficient in terms of the sterilizing effect against the pathogenic bacteria such as Escherichia coli, the rinsing property, and the skin irritation.

In addition, a detergent composition comprising an anionic surfactant and an alkyl amino acid surfactant (see Patent Document 2 and Patent Document 4), a detergent composition comprising an anionic surfactant and an alkylaminodicarboxylic acid surfactant (Patent Document 3 and Patent Reference 5) has been proposed.

According to these proposals, prescriptions excellent in hypoallergenic, foamy, and rinse-off properties can be realized, but they are not sufficiently satisfactory for the bactericidal effect against pathogenic bacteria such as Escherichia coli and pH stability.

Accordingly, it is desired to provide a liquid detergent composition that is excellent in bactericidal effect against E. coli, pH stability, foam performance, and rinsability, and has little skin irritation.

The water was finally balanced to 100% by mass, and the pH was measured after stirring well. In addition, the pH was measured by using a pH meter (HM-30V, made by Do-Kake KK) and stabilizing a sample at 25 캜 for 2 minutes.

Thereafter, the container was filled in a container (discharge amount: 1 mL, nozzle diameter (inner diameter) 3.5 mm, manufactured by Cyanide) equipped with a pump dispenser, and was provided for each evaluation.

Subsequently, various properties were evaluated for each of the obtained liquid detergent compositions (hand soap) of Examples 1 to 42 and Comparative Examples 1 to 12 as follows. The results are shown in Tables 1 to 10.

&Lt; Evaluation method of sterilizing power &

(1) Preparation of bacterial liquid

The following Escherichia coli was prepared so that the initial bacterial count was 10 ⁸ cells / mL.

E. coli: Escherichia coli NBRC3972 (obtained from NBRC, Seihinkokagi, Tokuritsu Kyosai)

(2) Test liquid

Each of the obtained liquid detergent compositions (hand soap) was diluted 6 times with 3-degree water hardness to prepare a test liquid.

(3) Sterility Test

(1) was added to 9 mL of the test solution (2) at 25 DEG C and sufficiently stirred. After 60 seconds of addition, 4.5 mL of SCDLP agar medium (Soybean-Casein Digest Broth with Lectin & Polysorbate 80, manufactured by Wako Pure Chemical Industries, Ltd.) to prepare a 10-fold diluted solution. The same procedure was repeated to obtain each dilution. 1.0 mL of each dilution was collected in a CHAREA, and 15 mL of SCDLP agar medium was added to homogenize and cultured for 1 day (agar flat plate dilution method), and the number of viable cells was counted. The sterilizing power was calculated based on the following formula from the initial bacterial count and viable count, and the sterilizing effect was evaluated based on the following criteria. In addition, the larger the value, the higher the sterilizing power.

Sterility = -log ₁₀ (number of viable cells / number of viable cells)
