The active ingredients of laundry detergent are mainly non-ionic surfactant, and its structure includes hydrophilic end and oil-loving end, in which oil-loving end combines with stain, and then separates stain and fabric through physics movement ( such as hand rub, machine movement ). At the same time, surfactants reduce the tension of water, so that water can reach the surface of fabric, so that the effective ingredients play a role.
洗衣液的有效成分主要是非離子型表面活性劑，其結構包括親水端和親油端，其中親油端與汙漬結合，然後透過物理運動（如手搓，機器運動）使汙漬和織物分離。同時表面活性劑降低水的張力，使水能夠達到織物表面，使有效成分發揮作用。
