How to Use Starphere T5-PI34 in Your Formulations
Understanding Starphere T5-PI34
Starphere T5-PI34 are small, vibrant red spheres designed to make oral care products look and feel more engaging. Think of them as an eco-friendly evolution of the colorful specks seen in premium toothpastes. Made from natural corn starch, these beads provide a pop of color in the tube and gently dissolve during brushing—offering a safe, modern alternative to plastic microbeads.
For formulators, these beads are a simple, high-impact tool for product differentiation. They are engineered to remain intact in high-water toothpaste bases yet break down quickly with brushing. Mannitol in the system contributes to binding and a mild, pleasant sweetness suitable for oral care. The optimized particle size (600–850 μm) is visually distinct while remaining comfortable and non-abrasive in use.
Formulation Tips
Recommended Usage Rate: 0.5%–2.0%. Use ~0.5% for a subtle speckled look; 1.5%–2.0% for a dense, colorful effect.
When to Add: Add during the final step (cool-down phase) once the base is below 40°C (104°F). Avoid hot addition or high shear that could prematurely break the spheres.
Dispersion: Gently fold into the finished toothpaste or gel base until evenly distributed. Over-mixing can damage the beads.
Base Selection: Beads show best in clear or translucent gel bases. In opaque, white pastes the color effect is muted.
Suspension: Ensure sufficient viscosity to keep beads suspended (e.g., xanthan gum, carbomer, or comparable oral-care rheology modifiers).
