Description

本発明は硬質表面用液体洗浄剤組成物に関する。   The present invention relates to a liquid cleaning composition for hard surfaces.

食器や調理器具等の硬質表面の手洗い洗浄に用いられる洗浄剤組成物は、利便性から液体であることが好ましい。このような洗浄剤組成物には、皿、茶碗、湯呑み等の食器、包丁、鍋、フライパン等の調理器具、換気扇や台所周辺の壁、ガラス、冷蔵庫等に付着した強固な油汚れを簡単に除去する高い洗浄力と、豊かな泡立ち(起泡性)が求められる。そのため、通常の界面活性剤だけでは満足する洗浄力を得ることができず、従来、直鎖アルキルベンゼンスルホン酸塩等の陰イオン界面活性剤とアミンオキシド型界面活性剤等とを組み合わせることにより、良好な洗浄力や起泡性を有する液体洗浄剤組成物が開発されている。   The cleaning composition used for hand-washing hard surfaces such as tableware and cooking utensils is preferably a liquid for convenience. Such cleaning compositions can easily remove strong oil stains attached to dishes such as dishes, teacups, and cups, kitchen utensils, cooking utensils such as pans and pans, ventilation fans and kitchen peripheral walls, glass and refrigerators. High detergency to remove and rich foaming (foaming property) are required. For this reason, satisfactory detergency cannot be obtained only with ordinary surfactants. Conventionally, a combination of an anionic surfactant such as a linear alkylbenzene sulfonate and an amine oxide surfactant is favorable. Liquid detergent compositions having excellent detergency and foaming properties have been developed.

特許文献1には、陰イオン界面活性剤、アミンオキシド型界面活性剤、及びアルキルグリセリルエーテルを含有する、洗浄効果に優れる食器洗い用洗浄剤が開示されている。また、特許文献2には、陰イオン界面活性剤、両性界面活性剤、非イオン界面活性剤、及び分子内に複数の水酸基を有する化合物を含有する、洗浄力、泡立ち、泡質、低温安定性に優れた液体洗浄剤組成物が開示されている。しかしながら、これらの液体洗浄剤組成物は、洗浄力、起泡性の点で十分ではなく、これらの性能をさらに向上させた液体洗浄剤組成物の開発が望まれている。   Patent Document 1 discloses a dishwashing detergent containing an anionic surfactant, an amine oxide surfactant, and an alkyl glyceryl ether, which has an excellent cleaning effect. Patent Document 2 discloses an anionic surfactant, an amphoteric surfactant, a nonionic surfactant, and a compound having a plurality of hydroxyl groups in the molecule, detergency, foaming, foam quality, and low temperature stability. An excellent liquid detergent composition is disclosed. However, these liquid detergent compositions are not sufficient in terms of detergency and foamability, and development of liquid detergent compositions that further improve these performances is desired.
