The main ingredients of washing powder are: surfactant (commonly used is sodium dodecylbenzene sulfonate), soft water (commonly used is sodium tripolyphosphate), alkali agent (commonly used is soda ash and sodium silicate), Bleach (some laundry detergents use sodium borate for bleaching), enzymes (mainly complex enzymes composed of hazelnut agent, lipase, cellulase, etc.), bleach whitening agent, carboxymethyl cellulose (such as anti-redeposition function), flavors, pigments, and fillers (mainly sodium sulfate, which plays a filling role and makes the product look rich)

Washing powder has a shelf life. It will also expire. The shelf life of laundry detergent is usually affected by factors such as its ingredients, storage conditions, frequency of use and brand quality. Generally speaking, the shelf life of unopened laundry detergent is about three years, and the shelf life after opening is about one year. Especially in washing powder with added enzyme substances, the protease is active and may lose activity after about a year of storage, thus affecting the washing effect.

In order to extend the shelf life of laundry detergent, it should be stored in a dry, cool place. If the temperature is too high, the essence will evaporate and the enzyme will lose activity. Keep out of direct sunlight and keep tightly sealed to prevent moisture and odors from penetrating. In addition, reasonable control of usage to avoid waste and overuse is also an important measure to extend the shelf life of laundry detergent.

Please note that expired laundry detergent may not be effective. It is recommended that when purchasing the product, check the production date and expiration date and use it within the expiration date.
