How to Use Starphere G5-BR39 in Your Formulations

Understanding Starphere G5-BR39

Starphere G5-BR39 offers a simple way to make your products more engaging and visually exciting. Think of them as tiny, solid spheres filled with bronze pigment. They stay suspended in your product as attractive specks, and when the product is massaged onto the skin, gentle pressure and friction cause the spheres to break, releasing a warm, bronze color in a delightful burst. This provides an instant visual cue that the product is activating.

For the technical-minded formulator, these granules use a matrix of Zea Mays (Corn) Starch and Microcrystalline Cellulose. This natural, biodegradable structure is firm enough to withstand mixing and storage, yet soft enough to break down easily upon application without harsh abrasion. The 250–850 μm particle size is optimized for visual impact and a pleasant, mild exfoliating feel.

Formulation Tips

Usage Rate: Use 0.5%–3%. Start at ~1% for noticeable speckling and color payoff; increase for a more dramatic transformation or denser visual effect.
When to Add: Incorporate during cool-down (below 40°C / 104°F). Avoid high temperatures and high shear to prevent premature breakage.
Suspension Is Key: Formulas should be sufficiently viscous to suspend the granules (gels, thick creams, or anhydrous systems). In thinner lotions, use rheology modifiers (e.g., carbomer, natural gums) to prevent settling.
Mixing: Fold in gently with a slow paddle or anchor mixer. Avoid high-speed or high-shear mixing.

Key Performance Benefits

Transformative Visual Effect: Creates an exciting color-burst experience that signals product activation. The warm bronze hue imparts an elegant, sun-kissed look.
Enhanced Sensory Experience: Provides a gentle, pleasant exfoliating sensation that smooths and refines without harshness.
Excellent Stability: Granules remain intact and visually distinct in the base until intentionally broken during application.
Natural and Biodegradable: Based on corn starch and cellulose for an eco-friendly alternative to plastic microbeads.
