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 during 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 during 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 cleaning agents can provide excellent cleaning performance, rinsing properties, and storage stability at low temperatures, the use of hydrocarbon group sulfate or hydrocarbon group sulfonate and the total amount of surfactant There is no technical suggestion about.

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 and the ratio of water-miscible organic solvent to surfactant.
