The invention in this application does not make the foam volume decrease even with use of the small quantity, it designates that it was superior in bubble, was superior in foam quality, was superior in the adhesion pollution control effect of the dirty component, offers the cleaning agent composition of the shampoo, the body soap, the hand soap and the laundry detergent etc as purpose. Jointly using the building a bridge conversion soybean polysaccharide which did building a bridge conversion treatment in water soluble soybean polysaccharide, with the surface active agent, by the fact that you obtain the cleaning agent composition, you could obtain the foam volume and the foam quality improvement effect which are superior at the tonnage which is fewer than former water soluble soybean polysaccharides. Furthermore, it became dirty in the cleaning agent composition for laundry, it discovered the fact that it has possessed the adhesion depression effect to the clothing fiber of the component.本願発明は、少量の使用でも泡量を減少させない、泡立ちに優れ、泡質に優れ、汚れ成分の付着汚染防止効果に優れた、シャンプー,ボディーソープ,ハンドソープ,洗濯洗剤等の洗浄剤組成物を提供することを目的とする。水溶性大豆多糖類に架橋化処理を行なった架橋化大豆多糖類を、界面活性剤と併用して洗浄剤組成物を得る事で、従来の水溶性大豆多糖類よりも少ない量で優れた泡量と泡質向上効果が得られた。更に、洗濯用洗浄剤組成物において、汚れ成分の衣類繊維への付着抑制効果を有していることを見出した。
