Description

Description Cleaning composition Technical field

The present invention relates to a detergent composition which is mild to the skin, has good foaming, and is excellent in a feeling of feeling after rinsing and stability at low temperatures. Background art

Detergent compositions that come into direct contact with the skin, such as shampoos and whole body cleansers, are required to have low irritation to the skin in addition to detergency, foaming properties, and feeling of use. Sulfate surfactants, which are widely used as cleansing ingredients, have high foaming performance, but may seep when shampooing, and if used for a long period of time, may cause sensitive hands and skin to become rough. In addition, if the cleaning power is high, there is a problem that the shampoo squeezes the hair during rinsing and deteriorates the usability. When a conditioning component such as a cationic polymer or a silicone compound is added to improve the rinsing property, the foaming property is reduced.

In contrast, ether carboxylic acid surfactants, N-acyl amino acid surfactants, acyl isethionates, acyl taurine surfactants, polyoxyethylene fatty acid amide ether sulfate surfactants, amidoamine amphoteric surfactants Surfactants with low irritation to the skin, such as agents, have been developed. However, all of these surfactants have poor foaming properties. Therefore, when used in a detergent composition, it is necessary to use a large amount of a sulfate type surfactant or a betaine type surfactant. Was. When the amount of the surfactant used in combination is increased, the foaming property is improved, but the characteristic of these surfactants, which is inherently low irritation, cannot be utilized. Some of these surfactants were inferior in low-temperature stability depending on the type. An object of the present invention is to provide a detergent composition that is less irritating to the skin, has good foaming, and has excellent low-temperature stability. Disclosure of the invention
