How to Use Starpearl SP-RA4-GO2535A in Your Formulations
Understanding These Gold Pearls
Starpearl SP-RA4-GO2535A is a functional delivery system that adds both visual luxury and skincare benefits to your products. Think of them as soft, golden gel pearls suspended in your base. When the product is rubbed onto the skin, the pearls burst and release their actives, creating a memorable multi-sensory experience and a visible signal of performance.
Technically, these are agar-based hydrogel capsules. The agar matrix encapsulates a blend of humectants and skin-conditioning actives, including Panthenol (Pro-Vitamin B5) and Beta-Glucan. Cosmetic-grade iron oxides and titanium dioxide create the rich gold appearance, while the soft shell collapses completely upon application for a smooth finish.
Formulation Tips
- When to Add: Add during the cool-down phase below 40°C (104°F). Heat will soften or melt the pearls.
- Usage Rate: Use 0.5%–3%. Start at ~1% for a clear visual impact; increase for a denser, more dramatic look.
- Suspension is Key: These large pearls (2.5–3.5 mm) need a sufficiently viscous base. Build structure with rheology modifiers (e.g., carbomer, xanthan gum, or other polymer thickeners) to prevent settling.
- Mixing: Fold gently into the finished, thickened base. Avoid high shear to prevent damaging the pearls.
- Preservation: The pearls are preserved, but your final water-based formula still requires a robust, broad-spectrum preservative system.
Key Performance Benefits:
- Dramatic Visual Appeal: Large, uniform gold pearls instantly communicate luxury and quality on the shelf and in use.
- Multi-Sensory Experience: Satisfying burst on application enhances user engagement and perceived efficacy.
- Targeted Active Delivery: Encapsulates Panthenol and Beta-Glucan and releases them at the moment of application.
- Smooth Application: Soft agar shell collapses fully without grit or residue, leaving only the feel of your base.
- Formulation Versatility: Elevates clear serums, thick gels, hydrating masks, and rich body lotions.
