Description

Liquid detergent composition

The present invention relates to a liquid detergent composition, particularly a liquid detergent composition for textiles such as clothing.

There are two types of clothes washing methods: hand washing and washing machine washing.

In the Asian region, clothes are often washed by hand, and even in the case of washing machine washing, preliminary washing by hand is often performed before washing machine washing.

This is because in Asia, people often eat oil-rich foods, and such cooking oil stains on clothing are difficult to remove effectively with a washing machine alone, and are washed by hand. It is possible to effectively remove oil stains from cooking only after pre-treatment such as pre-applying clothes cleaners to places with oil stains and then washing them in a washing machine. It is.

In the field of cleaning agents, cleaning ability against dirt, richness of foam at the time of washing, and ease of rinsing after washing are all important issues. This is particularly evident in hand-washing cooking oil stains.

In washing, oil stains in cooking are very stubborn, so an excellent cleaning ability against this is required, and in hand washing, sufficient foaming during scouring is reminiscent of high washability, and a cleaning agent Sufficient foaming is required because it affects user satisfaction. From the viewpoint of saving water and saving labor, it is strongly desired that the foam disappears quickly during rinsing and that rinsing is completed with a small amount of water. Conventional cleaning agents cannot combine the three points of washing ability against dirt during washing, especially cooking oil stains, richness of foam when washing, and ease of rinsing after washing. There is a need for new technologies that can serve as both.

Patent Document 1 discloses a kitchen containing an alkyl (C = 10-18) amine oxide and a polyoxyethylene alkyl (C = 10-20) ether sulfate having an average addition mole number of 0.5-5. Although it has been disclosed that liquid detergents can provide excellent cleaning performance, rinsing properties and storage stability at low temperatures, technical suggestions for the use of hydrocarbon-based sulfates or hydrocarbon-based sulfonates There is no.

Patent Document 2 discloses that a liquid detergent composition containing an alkyl or hydroxyalkyl (C = 10 to 18) amine oxide and a predetermined polyoxyalkylene alkyl ether sulfate has a high cleaning ability and beneficial low temperature storage. Although it is disclosed that the effect of stability can be obtained, there is no technical suggestion about the use of hydrocarbon group sulfate or hydrocarbon group sulfonate.

<Preparation method of "cotton short sleeve shirt for evaluation">
A “cotton short sleeve shirt for evaluation” was prepared by the following method. Specifically, a washing machine (Qingdao Haier Washing Machine Co., Ltd., Standard: XQS60-ZY1128) and 2.5 kg of a commercially available cotton short-sleeved shirt (Shanghai Three Gun (group) Co., Ltd. Manufacture, round neck, size: L, 100% cotton), add detergent, hard water (CaCl ₂ and MgCl ₂ .6H ₂ O 6: 4 at a temperature of 20 ° C. and 89.5 mg / L calcium carbonate equivalent) The mixture was mixed at a molar ratio of 5), and the conditions described below were set, and washing was repeated 5 times. The conditions for washing each time were a water amount of 54 L and a cleaning agent dose of 27 g (that is, the cleaning agent dose with respect to the water amount (the cleaning agent (g) / water (L)) was 0.5 g / L) and the washing time was 12 minutes. Rinse the water twice and dehydrate for 5 minutes. The detergent is a nonionic surfactant (polyoxyethylene alkyl ether obtained by adding an average of 6 moles of oxyethylene groups to a primary alcohol having 12 alkyl groups, trade name: EMULGEN 108) And a mixture of amorphous sodium silicate and sodium carbonate at a mass ratio of 1: 1: 3.
Put the last dehydrated cotton short-sleeved shirt into a two-tank washing machine (Matsushita Manufacturing, XPB52-500S) and use hard water with a temperature of 20 ° C. and a calcium carbonate equivalent of 89.5 mg / L. Rinse with running water until the water disappeared completely, followed by dehydration for 5 minutes and then air drying to obtain a “cotton short sleeve shirt for evaluation”.

<Measurement method of alkalinity>
The measurement method of the alkalinity of the water used for preparation of the said water dilution is shown below (Hereinafter, unless otherwise specified, the alkalinity of this invention says what was measured by this method).
Take 100 mL of test water in a 200 mL beaker and add 0.15 mL of bromocresol green-methyl red / ethanol solution (manufactured by Wako Pure Chemical Industries, Ltd.) as an indicator. When there is residual chlorine in the test water, a sodium thiosulfate solution (0.3 w / v%) is added to 100 mL of the test water in advance to remove the residual chlorine. This solution is titrated with 10 mmol / L sulfuric acid while gently stirring until the color of the solution changes from blue to reddish purple. The alkalinity is calculated by the following formula.
Alkalinity (CaCO ₃ mg / L) = a × 10
Here, a: 10 mmol / L sulfuric acid (mL) required for titration
When the color change due to the indicator is not clear, such as a colored sample, a pH meter is used instead of the indicator, and the amount of 10 mmol / L sulfuric acid (ml) required until the pH value is 4.8 is defined as a.
