Problems solved by technology

However, when the pellets are applied to the laundry detergent, the laundry detergent is a liquid environment, which can destroy the coating layer, resulting in direct contact between the pellet core and the laundry detergent during storage, resulting in suspended matter in the laundry detergent, and the vitality of the functional additives. Loss, reduced washing or builder effectiveness

Abstract

A micropill for laundry detergent and a preparation method thereof, the micropill includes a pellet core and a coating layer covering the pellet core, and the coating layer includes the following raw materials in parts by weight: 5 to 20 parts of high-carbon fatty alcohol , 5 to 30 parts of microcrystalline wax, 20 to 50 parts of polyethylene glycol, and 5 to 20 parts of hydrogenated castor oil, wherein the sum of the content of high-carbon fatty alcohol and microcrystalline wax is 5 to 5 parts of the content of hydrogenated castor oil 7 times. In the present invention, by adjusting the composition and ratio of the coating layer of the pellets, the coating layer can be stably present in the laundry liquid environment, and the coating layer of the pellets is prevented from being dissolved and destroyed by the laundry liquid after being stored in the laundry liquid for a period of time; and , Under the water body environment and the impact of water flow during cleaning, the coating layer can be partially or completely destroyed, releasing the functional additives in the pellet core to improve the washing effect.

Description

technical field [0001] The invention relates to the field of washing products, in particular to a pellet used for laundry detergent and a preparation process thereof. Background technique [0002] Washing powder, soap powder, and laundry detergent are common washing products in life. When cleaning, people usually add additional functional additives such as bactericides, fragrance beads, enzyme preparations, and fabric conditioners to improve the washing and washing effects, and to effectively clean specific types of clothing. [0003] In order to achieve the washing effect, it is necessary to use a variety of additives. There are two ways to use them. The first way is to use a variety of products. For example, when consumers want to sterilize, deodorize and make clothes soft, they need to use laundry detergent and fungicides. , softener three products to achieve the above effects. [0004] The second way is to wrap a pellet core composed of various functional additives in ...
