Mixing process impacts finished properties

Milling not only provides intimate mixing, but also eliminates variation in ribbon thickness and cmshes lumpy materials, eg, overdried soap, which might impact finished bar texture. Milling is also used for the formation of the proper bar soap crystalline phase, which plays a critical role in both the performance properties of the soap bar and the handling characteristics of the in-process soap. For example, too hot a milling temperature can create sticky soap that is difficult to process further. 

All of the mix ingredients are added together to form a slurry. Part of the formulation will include some solvents. These are used to dissolve other mix chemicals such as binders during the milling process. In addition, these solvents add to the formulation s rheological properties and effect the manner in which the finished mix flows. This directly impacts the manner in which the particular formulation performs on...
