Description

Pellet for laundry detergent and preparation method thereof
Technical Field
The invention relates to the field of washing products, in particular to a pellet for laundry detergent and a preparation process thereof.
Background
Washing powder, soap powder and laundry detergent are common washing products in life. In washing, people usually add functional aids such as bactericides, fragrance-retaining beads, enzyme preparations, fabric conditioners and the like additionally to improve washing and washing-assistant effects and effectively wash specific types of clothes.
In order to achieve the washing effect, a plurality of auxiliary agents are used, and the first way is to use a plurality of products, for example, when a consumer wants to sterilize and deodorize and soften clothes, three products, namely a laundry detergent, a bactericide and a softener, are needed to achieve the effect.
The second mode is that the pellet core made of various functional auxiliary agents is wrapped in the pellet structure. When the washing product is stored, the functional auxiliary agent is wrapped in the coating layer, so that the direct contact between the functional auxiliary agent and the washing product is effectively avoided, and the influence on the washing effect caused by the reaction of the components with incompatibility is prevented. When the washing article is used, the coating layer is dissolved and cracked when clothes are washed, and the internal functional auxiliary agent is contacted with the fabric to generate a specific function and improve the washing and washing assisting effects.
Patent CN108330034A discloses a pellet particle added in laundry soap, which uses polyvinyl chloride, polyvinyl alcohol, polyethylene glycol and other substances as heat insulation filler, and combines with binder and pigment to form a coating layer, so that protease enzyme inside the coating layer can be stably present in the coating layer, and when the washing product is used, the coating layer is peeled off to release the enzyme, thereby improving the decontamination capability. Patent CN102433225B discloses an alkaline protease coated pellet, wherein the coating layer of the pellet mainly adopts dextrin, starch and bean powder, the mixing uniformity with washing powder is good, the dissolving speed is high, the storage period is long, and the activity loss of the functional auxiliary agent in the pellet is small.
In the prior art, the coating layer of the pellet is mainly applied to washing powder and cleaning soap. Washing powders and soaps are solid environments and require a coating layer that is isolated in storage and rapidly dissolved in the rinse state. However, when the pellets are applied to a laundry detergent, the laundry detergent is a liquid environment, which can damage the coating layer, resulting in direct contact between the pellet core and the laundry detergent during storage, resulting in generation of suspended substances in the laundry detergent, loss of activity of functional auxiliaries, and reduction of washing or washing-assistant effects.

The purpose is realized by the following technical scheme:
the pellet for the laundry detergent comprises a pellet core and a coating layer for coating the pellet core, wherein the coating layer comprises the following raw materials in parts by weight: 5-20 parts of high-carbon fatty alcohol, 5-30 parts of microcrystalline wax, 20-50 parts of polyethylene glycol and 5-20 parts of hydrogenated castor oil.
In the technical scheme, the structure of the pellet is the same as that in the prior art, and the pellet comprises a pellet core and a coating layer, wherein the coating layer coats the pellet core in the pellet core so as to isolate the pellet core from the external space.

And (3) testing the stability of the pellets:
and (3) adding 5 parts of acetic acid bacteria cellulose into 100 parts of the commercially available laundry detergent A, stirring at the rotating speed of 1000rpm for 20 minutes to obtain a test laundry detergent environment, respectively adding the pellets M1-M4 into the laundry detergent, and uniformly stirring to obtain the laundry detergents D1-D4.
The laundry liquids D1-D4 were placed in environment 1, environment 2 for 7 days and 14 days. Wherein the environment 1 is an oven at 40 +/-2 ℃, and the environment 2 is a refrigerator at-5 +/-2 ℃. And (3) pouring the liquid laundry detergents D1-D4 into a washing machine for washing for 1 hour, wherein the volume of clothes accounts for one third of the total volume of the washing drum, the rotating speed of the washing drum is 800rpm, and sampling to detect whether unbroken pellets exist in the washing liquid. The test results are shown in table 1:
