Charles Ross and Son Company - Mixing Equipment for Sunscreen and Sun Tan Lotions

Mixing is a critical step in the production of sunscreen, largely because proper dispersion of the active ingredients and additives directly impacts the end product's efficacy and stability.

This bulletin describes several high shear mixing technologies utilized in the manufacture of sunscreen and sun tan lotions. Mixer selection is based on a number of factors, primarily viscosit... (read more)

Charles Ross and Son Company - Mixing Equipment for Pigment Dispersions

Pigment dispersions are typically prepared in a two-step process: (1) powder wet-out in a batching tank and (2) one or more passes through a mill to achieve the desired fineness of grind.

The costly and time-consuming milling step is often a production bottleneck which in the past has forced manufacturers to add more milling equipment to handle multiple passes or simply keep up wi... (read more)

Charles Ross and Son Company - Recommended Mixing Equipment for Dental Composites

Dental composites are synthetic polymers filled with reinforcing glass and/or ceramic particles.

A typical mixing procedure starts with blending two or more monomers often of significantly different viscosities. Various particle size fillers are then added to the liquid binder and mixed under vacuum until a homogenous paste is obtained. High amounts of fillers render most dental c... (read more)
