Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel liquid detergent composition for hard surfaces, and more particularly to a liquid detergent composition for foaming and detergency, which satisfies basic functions as a detergent and has sufficient sterilization performance. And a liquid detergent composition for hard surfaces that is excellent in mildness and finish on hard surfaces.

[0002]

2. Description of the Related Art Conventionally, anionic surfactants, nonionic surfactants, and amphoteric surfactants have been used for cleaning hard surfaces of various dishes and utensils, and glass and ceramics of houses. A cleaning agent appropriately combined with an activator or the like is used. These have sufficient foaming performance and detergency, and are commercially available as mild detergents for hand skin. On the other hand, in recent years, with an increase in consumers' awareness of hygiene, detergents provided with sterilization performance have begun to be marketed. However, these detergents provided with a disinfecting property have a problem that mildness of hand skin and finish of a hard surface after washing are impaired by the disinfectant added.

[0003]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, essential oils or extracts obtained from tea trees or their simulated compositions, surfactants, and organic compounds. A liquid detergent containing an acid or a salt thereof satisfies basic performance as a detergent such as foaming performance and detergency, as well as disinfecting performance and mildness to hand skin at the time of use, In addition, they have found that the finish of the hard surface is excellent, and have completed the present invention.
That is, according to the present invention, (a) an essential oil or extract obtained from a tea tree or a simulated composition thereof,
A liquid cleaning composition for hard surfaces, comprising (b) a surfactant and (c) an organic acid or a salt thereof is provided.
