Description

  The present invention relates to a foam container filled liquid detergent composition.

  Conventionally, as a cleaning base for liquid detergent compositions, for example, fatty acid salts, polyoxyethylene alkyl ether sulfates, monoalkyl phosphates and the like are known. Also, in the field of liquid cleaning, foam can provide a sense of satisfaction with cleaning as a kind of staging effect. The fatty acid salt is blended in many liquid detergent compositions because it is excellent in foamability and fineness of foam quality (see, for example, Patent Document 1). However, since the fatty acid salt has a strong detergency, crystals are likely to be precipitated due to the skin becoming thick after rinsing, pH change with time, temperature change, etc., and the former may be filled in a former container. There is a problem that clogging occurs in the porous membrane of the pump of the container, making it difficult to push the pump smoothly.

  In order to solve such problems, for example, it does not contain a fatty acid salt, and (A) aminopropionic acid amphoteric surfactant, (B) betaine amphoteric surfactant, and (C) N-acyl amino acid salt And / or N-acylmethyl taurine salt and / or alkyl sulfosuccinate salt, and (D) containing a sugar alcohol, the foam quality is fine, and the skin cleansing which can suppress the bulkiness of the skin after rinsing Have been proposed (see, for example, Patent Document 2). However, in this proposal, there is room for improvement in the elasticity of the foam and the durability of the foam, and there is a problem that the post-rinsing feeling remains slim and the refreshing feeling after the rinsing is insufficient.

  Therefore, the foam cleaner contained liquid detergent composition which has good foam elasticity and foam persistence, is less likely to clog the pump of the foamer container, does not have a heavy skin after rinsing, and provides a refreshing feeling after rinsing. It is desirable to provide
