Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は貯蔵安定性の優れた漂白洗剤組成物に関する。TECHNICAL FIELD The present invention relates to a bleaching detergent composition having excellent storage stability.
〔従来の技術及び発明が解決しようとする課題〕 過炭酸ソーダは漂白剤又は酸化剤として知られており、
過硼酸ソーダと並び代表的な酸素系漂白剤である。[Prior Art and Problems to be Solved by the Invention] Sodium percarbonate is known as a bleaching agent or an oxidizing agent,
Along with sodium perborate, it is a typical oxygen bleaching agent.
しかしながら、過炭酸ソーダは過硼酸ソーダに比べ、保

らないが、洗剤と混合したり、開封で放置した場合に
は、吸湿性が高いため、その貯蔵安定性において劣る。However, compared with sodium perborate, sodium percarbonate has a considerably poor storage stability, and has a major drawback that it loses available oxygen fairly quickly during storage. Since sodium percarbonate has a strong affinity for water, even a small amount of moisture will cause the surface to adsorb moisture, causing decomposition, and iron,
In the presence of ions such as copper, manganese, and cobalt, decomposition is further promoted, and the stability thereof is inferior to that of sodium perborate. Storage stability of sodium percarbonate is the same as that of sodium perborate when stored alone in an airtight container, but when it is mixed with detergent or left open, it has high hygroscopicity, so its storage stability is high. Inferior in sex.
また、近年、環境汚染上の問題から、トリポリリン酸ソ

炭酸ソーダはゼオライトによる触媒的分解作用によって
急速に有効酸素を失って分解していく。However, sodium percarbonate is extremely unstable in the detergent containing the zeolite, and the sodium percarbonate in the detergent containing the zeolite rapidly loses available oxygen and decomposes due to the catalytic decomposition action of the zeolite.
この傾向はゼオライト含有量が従来洗剤より多い高嵩密
度洗剤（0.5〜1.5g／cm３）において更に著しい。This tendency is more remarkable in a high bulk density detergent (0.5 to 1.5 g / cm 3 ) having a zeolite content higher than that of a conventional detergent.
また過硼酸ソーダはゼオライトに対して比較的安定であ

過炭酸ソーダや過硼酸ソーダは、低温での漂白効果に優

特徴を有しており、ゼオライト含有洗剤に安定に配合す
る技術の開発が熱望されていた。Sodium percarbonate and sodium perborate are excellent in bleaching effect at low temperature, and their decomposition products are non-polluting, so there is an eager need to develop a technology for stably blending zeolite-containing detergents. It had been.

If it is less than 0.1% by weight, the stabilizing effect due to the combined use with a higher fatty acid salt is low, and 5
No significant effect can be obtained even if blended in excess of weight%,
Not economically desirable. Among these (b) components, the alkali metal salt of hydroxyethyliminodiacetic acid represented by the formula (1) is particularly preferable. The ethylene diamine tetraacetate, nitrilotriacetate, etc. which have been widely used in the past cannot provide a sufficient stabilizing effect.
