How to Use Starpearl SP-RA4-BK2535 in Your Formulations
Understanding Starpearl Black Caviar Pearls
Starpearl SP-RA4-BK2535 provides an instant visual upgrade to any formulation, making your product look and feel exceptionally luxurious. Think of them as tiny, soft bubbles that hold beneficial ingredients. These large, glossy black pearls are made from agar (a seaweed derivative) and are designed to float beautifully in a thick gel or cream. When a user rubs the product onto their skin, the pearls gently burst, releasing a dose of skin-soothing ingredients like Panthenol (Pro-Vitamin B5) and Beta-Glucan. This creates a multi-sensory experience, combining stunning visuals with a delightful application feel that signals a high-performance product.
For the advanced formulator, these gel-based pearls serve as a sophisticated delivery system. The agar matrix encapsulates water-soluble actives, protecting them within the formulation until the moment of application. This ensures a fresh delivery and enhances the user’s engagement with the product. The large 2.5–3.5 mm particle size makes them a prominent visual feature, ideal for products where a bold aesthetic is desired.
Formulation Tips
Always add the pearls during the final step of your formulation, the cool-down phase, when the batch temperature is at or below 40°C (104°F). Adding them to a hot mixture will cause them to soften or melt.
Because these pearls are large and relatively dense, they require sufficient viscosity to remain suspended. Use a gelling/thickening system (e.g., carbomer, xanthan gum, cellulosic polymers, or modern acrylate copolymers) to create a medium-to-high viscosity gel, lotion, or cream. Typical usage is 0.5–3% depending on desired visual density; start around 1% and adjust. The pearls are pre-preserved, but your finished product still needs a robust, broad-spectrum preservative system.
