Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent for hard surfaces, and more specifically, it is excellent in detergency and foaming property, and does not deteriorate in performance even during long-term storage at low temperature, and The present invention relates to a detergent composition for hard surfaces which is not irritating to hands and skin.

2. Description of the Related Art In today's world where safety awareness for human body is increasing more and more, in the case of detergents such as residential cleaners and kitchen cleaners which are often exposed to human skin, in order to moderate the effect on the skin. Various attempts have been made.
For example, the pH of the composition is adjusted to 5 to 6 (weakly acidic) to bring it closer to the pH of human skin so that its action on the skin becomes mild, and the main washing base is as mild as possible. There is a tendency to use things. Amino acid-based surfactants and alkylphosphoric acid-based surfactants have been introduced as such mild detergent bases (Japanese Patent Publication No. 50-4).
0125, Japanese Patent Publication No. 51-426023, Japanese Patent Publication No. 55
-9033, Japanese Patent Publication No. 58-27319). But,
Although these surfactants are hypoallergenic, they have drawbacks such as that they cannot always exhibit sufficient foaming power / cleaning power and poor low temperature stability.

Conventionally, sodium alkylbenzenesulfonate and sodium alkylethoxysulfate have been widely used as bases having excellent cleaning performance. However, these also have a strong degreasing power from the skin and are liable to cause rough hands. Was.

Therefore, in addition, a tertiary amine oxide,
It has been attempted to further improve various properties by using a co-surfactant such as higher fatty acid diethanolamide and at the same time to make the action on the skin milder.

However, although the action of various detergents on the skin has become milder than in the past, the present situation is that it has not yet reached a sufficiently satisfactory level.

[0006]

Therefore, a detergent composition for hard surfaces which is excellent in detergency and foaming property, does not cause performance deterioration even during long-term storage at low temperature, and has no irritation to the skin of hands. Things were wanted.

[0007]

In view of such circumstances, the inventors of the present invention have diligently studied, and as a result, the specific amidobetaine type amphoteric surfactants, nonionic surfactants, water-soluble solvents and water, which will be described later, were respectively added.
