Description

Liquid detergent composition for clothing

The present invention relates to a liquid detergent composition for clothing, and particularly relates to a liquid detergent composition for clothing that has excellent antibacterial performance and is suitable for hand washing.

In the Asian region, when washing clothes, there are still many cases in which washing is still done by hand, and the tendency to adopt the hand-washing method is particularly high for undergarment clothes.
In the process of hand washing, an appropriate amount of foaming provides a sense of fullness and security, and ease of rinsing can reduce the amount of water used and the feeling of fatigue during hand washing.
On the other hand, demand for antibacterial clothing is also increasing due to an increase in consumer awareness of bacteria. Currently, all common antibacterial liquid detergents use a combination of a cationic surfactant and an anionic surfactant, or a combination of a cationic surfactant and a nonionic surfactant. However, when a combination of a cationic surfactant and an anionic surfactant is combined, the antibacterial action of the cationic surfactant is weakened. Therefore, for antibacterial purposes, a larger amount than originally added alone. A cationic surfactant is required. However, if the concentration of the cationic surfactant is too high, it remains in the clothing and cannot be easily rinsed, and the stability of the composition system also deteriorates, and turbidity is likely to occur at low temperatures in the fall / winter season. Become.
Therefore, when designing antibacterial liquid detergent formulations, low temperature stability, foamability and rinsing performance must be considered together.

Hard water with 2.5 kg of commercially available underwear (made by THREEGUN, 100% cotton) using a washing machine (XQS60-ZY1128, made by Qingdao Haier) with a water temperature of 20 ° C. and a hardness converted to calcium carbonate of 89.5 mg / L Repeat the washing 5 times. Remove the treatment agent. The cleaning conditions are as follows. The amount of water was 54 L, washed for 12 minutes, rinsed with water twice, and dehydrated for 5 minutes. At that time, the mass of 1: 1: 3 nonionic surfactant (nonionic surfactant obtained by adding an average of 6 moles of ethylene oxide to linear primary alcohol having 12 carbon atoms), amorphous sodium silicate and sodium carbonate 0.5 g / L of the mixture mixed in ratio is used. Thereafter, using a two-tank washing machine (manufactured by Panasonic, XPB52-500S), the water was rinsed by flowing with hard water having a water temperature of 20 ° C. and a hardness converted to calcium carbonate of 89.5 mg / L.
Rinse tightly so that no foam remains, and dry the underwear from which the treatment agent and cleaning agent have been removed by air drying to obtain an underwear for evaluation.
3 L of tap water having a water temperature of 20 ° C. is poured into a circular basin (diameter 25 cm at the bottom, diameter 30 cm at the top, and height 12 cm). Thereto, 15 g of a liquid detergent composition for clothing (test sample) is added, and the mixture is stirred 30 times by hand and dissolved uniformly. Next, three sheets of evaluation underwear prepared by the above method were poured there, and one sheet of white cotton cloth (8 × 10 cm, made of cotton) in which the adjustment oil shown below was uniformly dropped to 0.7 g per sheet. Pour and leave for 5 minutes in a completely immersed solution. After leaving it for 5 minutes, the oil cloth is first washed 50 times (converted as one reciprocation (about 1 second) while rubbing the cloth and cloth). Rinse 10 times with each undergarment, and wash 20 times together in the basin. Then, the underwear is taken out and the state of the washing liquid immediately after squeezing on the basin and squeezing three sheets is confirmed. The bubble height is measured with a ruler inserted and expressed in centimeters.

* Preparation oil 1.0% by mass of lauric acid, 7.1% by mass of myristic acid, 5.3% by mass of pentadecanoic acid, 14.2% by mass of palmitic acid, 1.0% by mass of heptadecanoic acid, 3.6% by mass of stearic acid , 17.8% by mass of oleic acid, 30.0% by mass of triolein, 5.0% by mass of n-hexadecyl palmitate, and 15% by mass of squalene were heated to about 60 ° C. and uniformly dissolved and mixed.

(Iii) Evaluation of rinsability 5 L of tap water having a water temperature of 25 ° C. was poured into a circular washbasin (inner diameter of the bottom surface 25 cm, upper surface inner diameter 30 cm, height 12 cm), and the cotton short sleeve for evaluation narrowed down in the foaming evaluation Insert 3 shirts. After rinsing the cotton short-sleeve shirt for evaluation and loosening it in water, lift the loose cotton short-sleeve shirt for evaluation one by one, holding the Eli part up from the bath (clothing up to 5 cm above the surface of the washing water) Lift until the whole is removed), then rinse again and return to the water. Such rinsing by vertical movement is repeated 10 times for each cotton short-sleeve shirt for evaluation, and then the cotton short-sleeve shirt for evaluation is taken out, squeezed above the washbasin, and then the rinsing water is discarded. Then, the same operation as described above is performed once again, but the rinsing water of this time is retained and the height of the remaining foam is measured with a linear ruler. If there are too few bubbles and the height of the bubbles cannot be measured with a straight ruler, the ratio of the “area of the water surface covered with bubbles” to the “area of the entire water surface” is expressed in “%”. The evaluation results of AA and BB were regarded as acceptable.
Evaluation criteria:
AA: The water surface of less than 60% was covered with foam.
BB: The water surface of 60% or more and less than 100% was covered with foam.
CC: 100% of the water surface was covered with foam regardless of whether or not the height of the foam could be measured with a straight ruler.

Dispense 5 mL of diluted test sample into a non-bacteria-free test tube, add 0.1 mL of bacterial solution, and after 20 minutes of action, sterilize 4.5 mL into 0.5 mL of the mixture of test bacteria and test sample After adding a summing agent (1 g of peptone, 0.7 g of lecithin, 20 g of Tween (80), 1 L of distilled water and sterilized with 121 ° C. high pressure steam for 20 minutes), stirring and mixing, neutralizing for 10 minutes, Take 1 mL of the sample solution (or 2 to 3 different dilutions obtained by appropriate dilution), leave it in a sterile petri dish, and inoculate each sample solution or dilute solution into two dishes. After pouring onto an agar medium and homogenizing sufficiently, the petri dish is inverted after the agar has hardened and cultured, and then the number of viable bacteria is quantified (average value of two petri dishes). Instead of the test sample, PBS (2.83 g of anhydrous disodium hydrogen phosphate and 1.36 g of potassium dihydrogen phosphate was weighed and dissolved completely by adding 1 L of distilled water, and then the pH was adjusted to 7.2 to 7.4. A control sample is prepared according to the above-described procedure using a sterilized solution at 120 ° C. for 20 minutes. The sterilization rate is obtained by the following formula.

Bactericidal rate (%) = (viable cell count of control sample−viable cell count of test sample) / viable cell count of control sample × 100%
