The effect of clothing care agent (fabric softener) and laundry detergent on clothing is fundamentally different.
(1) The washing liquid is to separate the dirt from the clothes, and the detergent itself should also be separated from the clothes after the washing is completed. It can be said that the effect of washing liquid on clothes is "subtraction".
(2) The effect of clothing care agent (fabric softener) on clothing is to be absorbed by the fibers and to be retained on the clothing. It can be said that clothing care agents (fabric softeners) are "additions" to clothing.

【Laundry liquid】
The working principle is the same as traditional washing powder and soap, and the active ingredients are all surfactants. The active ingredients of the laundry detergent are mainly nonionic surfactants, the pH is close to neutral, and its structure includes a hydrophilic end and a lipophilic end, wherein the lipophilic end is combined with the stain, and then the physical movement (such as hand rubbing, machine movement) makes the stain and Fabric separation. At the same time, the surfactant reduces the tension of the water, so that the water can reach the surface of the fabric, so that the active ingredients play a role.
The washing liquid is gentle on the skin and has no irritating effect. After being discharged into the nature, it degrades faster than washing powder, and has become a new generation of detergent products.

【Cloth Care Agent】
Clothing care agent (fabric softener) does not remove stains on clothing. It is a clothing finishing agent, which is mainly made of cationic surfactant.
Its role is mainly to:
(1) Improve the condition of the fiber and restore the deformation of the fiber after wearing or washing. Keep it fluffy, soft and relatively natural.
(2) Reduce the friction coefficient between the fibers, so that the relative movement between the fibers can be free, and improve the feel of the fabric.
(3) After the fiber absorbs the care agent, the fabric can appropriately improve the water-repellent performance.
The scope of application of clothing care agents is mainly fluffy and soft clothing, such as cardigans, cashmere sweaters, blankets, towels, bath towels and some underwear. Sometimes in order to make the living room more warm, some textiles in the home such as curtains, sofa covers, etc. will also be treated with clothing care agents (softeners).
