Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a liquid detergent composition which can be used as a kitchen detergent and a household detergent suitable for cleaning hard surfaces.

[0002]

2. Description of the Related Art Satisfactory detergency has been obtained as a cleaning agent for cleaning hard surfaces such as various tableware, cooking utensils and counters, various glassware ceramics and porcelain.
Further, since it is inevitable to directly contact the hands and the skin during cleaning using these liquid cleaning agents, the rough skin on the skin such as the hands during use has been a problem. As a result, the development of a cleaning agent that has excellent detergency so that it does not interfere with direct contact with the skin of the hands and the like and is mild to the hands and the skin has been promoted. Based on such needs, it has been proposed to use a nonionic surfactant using a sugar fatty acid ester or an amphoteric surfactant using an amino acid derivative. Further, it has been proposed to use an anionic surfactant which has been conventionally used as a detergent, to reduce and alleviate skin irritation caused by the combined use of an amine oxide or an amphoteric surfactant. Certainly, these cleaning agents are considerably effective as compared with the conventional ones, but in the present situation, they are not yet sufficient.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid detergent composition for hard surfaces which satisfies the performance as a detergent such as detergency and is mild to the skin such as hands. Especially.

[0004]

According to the present invention, a liquid detergent composition containing 0.001% to 5% by weight of an extract of flowers and / or leaves of Bodaiju is used for hard surfaces. A liquid detergent composition is provided.

BEST MODE FOR CARRYING OUT THE INVENTION The bodige used in the present invention includes Tilia europaea of the family Tiliaceae and its homologous plants T. cardata, T. platyphyllos, T. sylves.
Examples include tris and T. nigneliana. The method for extracting flowers and / or leaves of Bodaiju used in the present invention is based on the method described below. Prior to the extraction, the flowers and / or leaves of Bojdju are thoroughly dried and subjected to a pretreatment of shredding and crushing. The solvent treatment is performed after the powder is formed and the solvent is easily extracted. The solvent used is water, a hydrophilic organic solvent, a water-containing hydrophilic organic solvent, other organic solvents, etc., and particularly water, lower alcohols such as methanol and ethanol, water-containing methanol, water-containing ethanol, propylene glycol, butylene glycol, chloroform. , Acetone, benzene, etc. are used. These solvents may be used as a mixture of two or more kinds. The solvent is used in an amount of about 500 to 1000 ml with respect to 100 g of the powder. The solvent extraction can be performed in a state where the temperature is elevated from room temperature, specifically 30 to 100 ° C. In addition to keeping the powder in a stationary state in the solvent for effective solvent extraction, the solvent containing the powder is agitated so that the solvent sufficiently penetrates into the powder. Is effective. After a certain period of time, the residue of the extract is removed by means such as filtration or centrifugation when the solvent extraction is completed. The obtained extract is as it is,
Alternatively, it is added to the liquid detergent in the form of a powder obtained by concentrating or by removing the solvent by evaporation in some cases to dryness. In the case of addition and use, the extract of Bodaiju (the state in which the solvent is removed) obtained by the above method is 0.001 to 5% by weight, preferably 0.1 to 1% by weight in the liquid detergent composition. It is blended so as to be%. If the amount is less than this range, the effect of alleviating the irritation to the hand skin is insufficient. On the other hand, if the blending amount is more than this range, the liquid detergent will turn brown and the aroma will be inferior, so that it will not be suitable as a product.
