Methods of making personal care compositions, such as dentifrices, involving the addition of rheology modifiers at a later stage in the personal care composition formation process.

Late stage addition of rheology modifier

A static mixer having one or more stages and/or elements. The static mixer may be scaled from bench size to any commercially desired size. During scale-up the surface area to void volume ratio is maintained constant. Maintaining this ratio constant may be accomplished by increasing the number of bars in each element of the static mixer.

Apparatus for in-line mixing and process of making such apparatus

A method of making high internal phase emulsions is described. The method forms high internal phase emulsion (HIPE) using a single pass through the static mixer. In alternative embodiments, the HIPE may be further processed to farther modify the size of dispersed phase droplets, to incorporate additional materials into the HIPE, to alter emulsion temperature, and the like.
