How to Use Starphere F5-BL45 in Your Formulations
Understanding Starphere F5-BL45
Think of Starphere F5-BL45 as tiny, colorful treasure chests for your formula. These vibrant blue beads are designed to do two things: make your product look amazing and deliver an active ingredient in a fun, satisfying way. They are solid spheres made from natural corn starch that hold a core of Tocopheryl Acetate (Vitamin E). In your product, they stay suspended as beautiful blue specks. When your customer rubs the product onto their skin, the gentle pressure and moisture cause the starch shell to break down, releasing the Vitamin E exactly where it’s needed.
For the expert formulator, these beads are a multi-functional sensory and delivery system. The matrix—composed of corn starch, microcrystalline cellulose, and mannitol—is engineered for controlled release upon mechanical friction. The 500–700 μm particle size is optimized for suspension in moderately viscous systems and provides a noticeable but non-abrasive sensory burst.
Formulation Tips
To get the best results, add Starphere F5-BL45 during the cool-down phase when your batch is below 40 °C (104 °F). Adding them to a hot mixture can soften the starch matrix and cause premature breakdown.
- Usage Rate: 0.5–3% of total formula. Use 0.5–1% for a subtle sprinkle; 1–3% for a more dramatic visual density.
- Suspension: In low-viscosity systems the beads will sediment. Build viscosity with rheology modifiers (e.g., carbomer, xanthan gum, or other gelling polymers) to create a network capable of holding 500–700 μm beads uniformly.
- Mixing: Fold gently with a spatula or use low-shear mixing at the end of processing. High shear can fracture beads before the consumer uses the product.
Key Formulation Benefits:
- Dramatic Visual Appeal: Bright blue spheres add premium, eye-catching aesthetics and communicate a unique feature story in clear gels, serums, and creams.
- Engaging Sensory Experience: Provides a satisfying burst-on-application that transforms routine use into a memorable, multi-sensory moment.
- Targeted Antioxidant Delivery: Releases Tocopheryl Acetate (Vitamin E) during rub-in to help protect skin against environmental stressors.
- Natural & Biodegradable: Starch-based, plastic-free beads offer an environmentally responsible alternative to microplastics.
- Optimized Particle Size: 500–700 μm is visible for a striking effect yet breaks down smoothly without a scratchy feel.
- Versatile & Easy to Use: Suitable for serums, gels, lotions, masks, and cleansers when added during cool-down with appropriate viscosity control.
