Description

Technical Field

[0001] The present invention relates to a foam cleaning agent composition that can be used to clean with elastic foam during cleaning, can provide a refreshing feeling after cleaning, and has excellent stability over time, without using gases such as carbon dioxide.

Background Art

[0002] Foam-type cleaning agents have less burden on the skin compared to liquid-type cleaning agents and have conventionally been widely used as cleaning agents for face washing and body washing. For example, in Patent Document 1, a composition for a non-gas former characterized by containing one or more of N-long-chain acyl-α-amino acids or salts thereof has been proposed, but the foam performance may be insufficient in some cases. In Patent Document 2, a cleaning agent for foam containing a stock solution containing N-acylglutamate, α-olefin sulfonate, and alkyl dimethylaminoacetic acid betaine and carbon dioxide has been proposed. However, in order to use compressed gas such as carbon dioxide, a pressure-resistant container is required and a large amount of various packaging materials are used, which requires a great deal of labor for recycling. In addition, there is a concern that the compressed gas released into the atmosphere during use promotes global warming, and there is still room for improvement in order to use it with an environmental load equivalent to that of a product that does not use compressed gas. In Patent Document 3, a cleaning agent combining an anionic surfactant such as acylglutamic acid, a nonionic surfactant, and a thickener has been proposed. Although it improves the foam performance, it may be inferior in the refreshing feeling after cleaning, and there is room for improvement.
