What Affects Laundry Pods Dissolution in Cold Water?

B2B buyers often ask about laundry pods dissolution in cold water. Therefore, they need to understand the factors. Cold water washing is very popular today. However, it creates a technical challenge for cold water laundry pods. If the pod does not melt fully, it leaves a residue on clothes. As a result, checking laundry pods quality is essential for OEM production.

01. The Role of Water Soluble Film

The outer film is the most critical part. First, the film must protect the liquid inside. Next, it must melt completely in the wash. Furthermore, the thickness of the water soluble film matters. If the film is too thick, it will dissolve slowly. Conversely, if it is too thin, it might break during shipping.

02. How Water Temperature and Flow Affect Melting

Water temperature plays a major role. Hot water makes the film melt fast. However, cold water slows down the process. Therefore, formulators must test the film carefully. In addition, water flow is important. Strong water flow helps the capsule break open. As a result, the ingredients mix into the water quickly.

03. Formula and Wash Cycle Impact

The liquid inside the pod also affects melting. For example, some thick liquids dissolve slowly. Furthermore, the wash cycle is key. A short wash cycle may not give the pod enough time. Therefore, we recommend testing the laundry capsule dissolving speed with your local machines.

04. How We Test for Residue and Quality

OEM factories must run strict tests. First, we use a standard washing machine. Next, we test the pods at different temperatures. After that, we check the clothes for any sticky residue. Finally, we adjust the formula or the film thickness. Consequently, we ensure the best laundry pods quality for your brand.
