How to Use Starpearl SP-RA5-PI3545 in Your Formulations
Understanding Starpearl SP-RA5-PI3545
Think of these Starpearls as tiny, soft bubbles of skincare that make your product look beautiful and feel special. For beginners, they are an easy way to add a dramatic “wow” factor and skin-benefiting ingredients to your formula. When you apply the product, the soft pearls gently burst, releasing soothing actives onto the skin.
For the expert chemist, Starpearl SP-RA5-PI3545 is a hydrogel-based delivery system. The pearls are primarily composed of agar, forming a soft, dissolvable shell that encapsulates a hydrating gel phase containing Panthenol (Pro-Vitamin B5) and Beta-Glucan. Their large particle size (3.5–4.5 mm) creates a prominent visual feature in clear or translucent systems, enabling premium, differentiated products where sensory payoff and aesthetics are key.
Formulation Tips
Usage rate: Use 0.5%–3%. Start near 1% for a subtle visual effect; increase for a more pearl-forward presentation.
When to add: Always incorporate during the cool-down phase below 40°C (104°F). Adding at elevated temperatures will soften the agar shell and can cause premature dissolution.
Suspension: These large pearls require sufficient viscosity and yield value to remain evenly dispersed. Build structure with suitable rheology modifiers (e.g., carbomer, xanthan gum, acrylates copolymers) to create a stable gel network that suspends the pearls.
Preservation: While the pearls are preserved, your final water-based product must include a robust, broad-spectrum preservative system to ensure overall formula safety and stability.
