Okay, I understand you're looking for a body cream formula with a water-burst texture that is easy to spread, non-sticky, moisturizing, helps brighten skin, and is suitable for sensitive skin, using the ingredients you mentioned and a 300W blender.

Based on your requirements and the ingredients you selected, particularly the desire for a "water-burst" texture, the Satin Cream Maker you mentioned is not typically used for this effect. A water-burst or water-drop texture requires a specific type of emulsifier that creates a water-in-oil macroemulsion.

Based on the search, WaterDropper™ is an emulsifier specifically designed to create this water-burst effect. We can incorporate this along with the beneficial ingredients you selected (Glycerin, Safe-B3, GlucoBright, Reservoir-Tech, Mild Preserved Eco) and a suitable oil phase like Mineral Oil (Very Light).

Here is a proposed formula and method:

Water-Burst Body Cream Formula (for 100g)

This formula is designed to provide a water-burst texture, moisture, brightening, and be suitable for sensitive skin.

• Phase A (Oil Phase):
  • Mineral Oil (Very Light): 15 g
  • WaterDropper™: 7 g
• Phase B (Water Phase):
  • Water (Distilled or RO): 63.9 g
  • Disodium EDTA: 0.1 g
  • Glycerin: 5 g
  • Safe-B3™ (Vitamin B3, Niacinamide): 3 g
  • GlucoBright™ (Acetyl Glucosamine): 2 g
  • Reservoir-Tech: 3 g
  • Mild Preserved Eco™ (Preservative-Free): 1 g

Total: 100 g

Mixing Instructions:

1. Prepare Phase B: In a separate container, add Disodium EDTA to the water and stir until completely dissolved. Then add Glycerin, Safe-B3, GlucoBright, and Reservoir-Tech. Stir well until all powders are fully dissolved and the mixture is clear.
2. Prepare Phase A: In your main mixing container, combine Mineral Oil and WaterDropper™. Stir briefly to combine.
3. Emulsification: Using your blender with a disperser head (if available) or an immersion blender, start blending Phase A at a low speed. While blending, slowly add Phase B to Phase A in a thin, steady stream. It is crucial to add the water phase slowly and blend at low speed to properly form the water-in-oil emulsion and achieve the water-burst effect. Do not add all the water phase at once. Continue blending at low speed until all of Phase B is incorporated and the mixture is uniform with the desired texture starting to appear. Avoid high-speed blending or using a homogenizer head, as this can prevent the water-burst effect.
4. Final Step: Add Mild Preserved Eco™ to the mixture and blend briefly at low speed to ensure it is fully incorporated.
5. Check the pH of the final product. The target pH is typically between 4.0-7.0 for optimal stability and efficacy of the actives. If needed, a very small amount of Citric Acid solution can be used to lower the pH, or a weak base solution (like Sodium Hydroxide solution) to raise it, adding drop by drop and checking the pH after each addition.

This formula utilizes the WaterDropper™ to achieve the unique water-burst texture while incorporating the moisturizing and brightening benefits of Glycerin, Safe-B3, and GlucoBright. Reservoir-Tech helps enhance the delivery of the water-soluble actives, and Mild Preserved Eco provides gentle preservation. Mineral Oil serves as a suitable, non-irritating oil phase.
