Description

Liquid detergent composition for clothing

technical field

The invention relates to a liquid detergent composition for clothing, in particular to a liquid detergent composition for clothing which has good antibacterial properties and is suitable for hand washing.

Background technique

In Asia, when washing clothes, the frequency of hand washing is still very high, especially for some intimate clothes, people prefer to use hand washing.

The right amount of sudsing performance provides a sense of enrichment and peace of mind during hand washing, and the ease of rinsing reduces water usage and hand washing fatigue.

On the other hand, as consumers become more and more aware of bacteria, people's demand for antibacterial clothing is getting higher and higher. At present, the combination of cationic surfactant and anionic surfactant, or the combination of cationic surfactant and nonionic surfactant are used in conventional antibacterial laundry detergents. However, when anionic surfactants and cationic surfactants are used in combination, the antibacterial effect of cationic groups will be weakened, so in order to achieve the purpose of sterilization, it is usually necessary to mix a larger amount of cationic surfactants than the original alone. agent. However, if the concentration of the cationic surfactant is too high, it will not only remain on the clothes and make the foam difficult to rinse off easily, but also make the system stability worse, and it is easy to precipitate turbidity at low temperatures in autumn and winter.

Therefore, when designing antibacterial laundry detergent formulations, it is also necessary to take into account low temperature stability, foaming performance and rinsing performance.

(ii) Evaluation of foamability

Undershirts for evaluation were prepared in the following manner.

2.5 kg of commercially available singlets (manufactured by Sangun, 100% cotton) were repeatedly washed with a washing machine (XQS60-ZY1128, manufactured by Qingdao Haier) using hard water with a water temperature of 20°C and a hardness of 89.5 mg/L when converted to calcium carbonate for 5 Second, remove the treatment agent. The washing conditions were 54 L of water, washing for 12 minutes, rinsing with stored water twice, and dehydration for 5 minutes. At this time, a nonionic surfactant (surfactant in which an average of 6 moles of ethylene oxide was added to a straight-chain primary alcohol with 12 carbon atoms), amorphous sodium silicate was used at 0.5 g/L 1. The mixture in which sodium carbonate is mixed in a mass ratio of 1:1:3. Thereafter, the water temperature was 20° C., and the hardness in terms of calcium carbonate was 89.5 mg/L, and the running water rinse was performed with a 2-tank washing machine (XPB52-500S, manufactured by Panasonic).

The rinsing was carried out until the foam completely disappeared when the rinsing was stopped, and the undershirt from which the treatment agent and cleaning ingredients had been removed was dried naturally and used as an undershirt for evaluation.

Inject 3L of tap water with a water temperature of 25° C. into a circular washbasin (25 cm in diameter at the bottom, 30 cm in diameter at the top, and 12 cm in height). 15 g of the liquid detergent composition for clothing (test sample) was added thereto, and stirred by hand for 30 times to completely dissolve it uniformly. Then, put 3 undershirts for evaluation prepared according to the above method into it, and then add a piece of cotton white cloth (8×10cm cotton) with 0.7g of adjusted oil dripped evenly, completely soak in the solution and place it for 5 minutes. After 5 minutes, Scrub the oilcloth 50 times first (convert the cloth and the cloth to rub each other back and forth (about 1 second) into 1 time), scrub each sweater 10 times respectively, and then rub the clothes in the basin 20 times together. After that, take out the sweater and put it on the face. Wring out the undershirt above the basin, and confirm the state of the washing liquid level immediately after wringing out three undershirts. Insert a straight edge to measure the height of the foam and express it in centimeters.

Adjustment oil: lauric acid 1.0 mass%, myristic acid 7.1 mass%, pentadecanoic acid 5.3 mass%, palmitic acid 14.2 mass%, margaric acid 1.0 mass%, stearic acid 3.6 mass%, oleic acid 17.8 mass%, 30.0% by mass of glyceryl trioleate, 5.0% by mass of n-hexadecyl palmitate, and 15% by mass of squalene were heated to 60° C., dissolved and mixed uniformly, and the resulting mixture was used as an adjustment oil.

The case where the evaluation result was "(circle)" and "(triangle|delta)" was set as pass.

Judgment criteria:

◯: The foam height is 2 cm or more.

Δ: The foam height is more than 0.3 cm and less than 2 cm.

×: Foam height is 0.3 cm or less.

(iii) Evaluation method of rinsability

Inject 5L of tap water with a water temperature of 25° C. into a circular washbasin (25 cm in diameter at the bottom, 30 cm in diameter at the top, and 12 cm in height). Three cotton half-sleeved shirts for evaluation that had been wrung out in the evaluation of foam properties described above were put in. After loosening the cotton half-sleeve shirts for evaluation in the rinse water, grasp the collar part of each loose cotton half-sleeve shirts for evaluation and lift them up (up to a height of 5 cm from the surface of the washing liquid as a whole), and then Put back in the rinse water again. For each cotton half-sleeved shirt for evaluation, repeat the rinsing with up and down movements 10 times, take out the undershirt, wring the undershirt over the washbasin, and then discard the rinse water, and then perform the same operation as above again, but Keep the rinse water from this rinse and use a ruler to measure the residual suds height. Assuming that there is too little foam and the ruler cannot measure the foam height, the ratio of the "area of the water surface covered by foam" to the "area of the entire water surface" is marked with "%". The case where the evaluation result was "(circle)" and "(triangle|delta)" was set as pass.

evaluation standard:

○: Less than 60% of the water surface is covered with foam.

Δ: 60% or more and less than 100% of the water surface are covered with foam.

X: 100% of the water surface is covered with foam, whether or not the height of the foam can be measured with a ruler.
