How to Use Starphere S5-YE45 in Your Formulations
Understanding Starphere S5-YE45
Starphere S5-YE45 are golden, starch-based cosmetic beads designed to add instant visual appeal while delivering Tocopheryl Acetate (Vitamin E) on application. These 500–700 μm spheres suspend in gels, creams, and cleansers, then gently collapse when rubbed into the skin, releasing their contents and disappearing without residue.
For the formulating chemist, the bead matrix is composed of Zea Mays (Corn) Starch, Microcrystalline Cellulose, and Mannitol—biodegradable, plant-derived materials that provide mechanical integrity in the pack yet break easily under shear during use. The 500–700 μm particle size provides a refined, visible effect that feels smooth and non-abrasive.
Formulation Tips
Add Starphere S5-YE45 in the cool-down phase below 40°C (104°F). Avoid high shear after addition to prevent premature breakage; gentle folding or slow paddle mixing is sufficient for even dispersion. Ensure adequate viscosity or yield value to keep beads suspended over shelf life.
- Usage Rate: 0.5–3% as supplied. Start at ~1% for a noticeable but elegant bead density; increase for a more dramatic visual effect.
- Suspension: Build viscosity with gums (e.g., Xanthan), carbomers, or acrylate copolymers. In emulsions, ensure sufficient internal structure or use polymeric thickeners.
- Compatibility: Suitable for water gels, emulsions, and surfactant systems. Add after neutralization/viscosity build and at final color to minimize shear exposure.
- Processing: Add last, under slow agitation. Scrape vessel walls/bottom to prevent bead clustering and ensure uniform distribution.
Key Formulation Benefits
- Instant Visual Appeal: Golden beads provide a premium, eye-catching look that signals efficacy and elevates perceived value.
- Antioxidant Delivery: Releases Tocopheryl Acetate upon application to help protect skin from environmental stressors.
- Smooth Sensory Payoff: Soft-bursting structure collapses cleanly with no grit or residue.
- Biodegradable Matrix: Starch/cellulose/mannitol shell is plant-derived and biodegradable for eco-conscious formulations.
- Refined Particle Size: 500–700 μm spheres are visibly distinct yet comfortable on the skin.
- Versatile Integration: Works in gels, creams/lotions, and clear cleansers with appropriate suspension.
