Cream Formulation for Brightening, Hydration, and Sun Protection

Subject: Proposed Cream Formulation and Mixing Instructions

Thank you for your inquiry! Based on your desired properties for a lightweight, fast-absorbing, moisturizing, brightening, and non-irritating cream with sun protection for your dry, sun-damaged skin, and the ingredients you provided, here is a proposed formulation and mixing guide.

We have calculated the percentages for Fractionated Coconut Oil and Zinc Oxide, and adjusted the DI Water percentage to complete the formulation to 100%.

Proposed Formulation:

• DI Water: 64%
• Safe-B3 (Niacinamide): 5% - Known for brightening, improving skin barrier, and reducing redness.
• GlucoBright (N-Acetyl Glucosamine): 4% - Works with Niacinamide for brightening and improving hydration.
• Alpha Arbutin: 1.5% - A popular skin brightening agent that helps reduce dark spots.
• Active Resveratrol: 5% - An antioxidant that can help protect the skin and has some brightening properties.
• Satin Cream Maker: 1% - The emulsifier that helps create the cream texture.
• Shea Butter (Ultra Soft): 5% - Provides rich moisture and a smooth feel.
• Cyclomethicone / Cyclopentasiloxane: 1% - A silicone that provides a lightweight, silky feel and helps with spreadability.
• Perfume: Just Milk: 0.5% - For fragrance.
• Phenoxyethanol SA: 1% - A broad-spectrum preservative.
• Fractionated Coconut Oil: 3% - A lightweight emollient that adds moisture without feeling heavy.
• Zinc Oxide 200nm EasyDisperse: 10% - A physical sunscreen agent providing broad-spectrum UV protection. Note: 10% Zinc Oxide provides some level of sun protection (typically SPF 10-15), suitable for daily incidental exposure. For prolonged or intense sun exposure, a higher percentage of Zinc Oxide (15-20%) or a dedicated high-SPF sunscreen is recommended. Higher percentages of Zinc Oxide may affect the cream's texture and feel.

Mixing Instructions:

This formulation involves heating and emulsifying. Please ensure you have appropriate equipment (like a scale for accurate measurement, heat-resistant beakers, and a homogenizer or stick blender).

• Phase A (Water Phase):

  • DI Water: 64%
  • Safe-B3: 5%
  • GlucoBright: 4%
  • Alpha Arbutin: 1.5%
  • Active Resveratrol: 5%
    Combine ingredients in Phase A. Heat gently to 70-75°C and stir until all powders are dissolved.

• Phase B (Oil Phase):

  • Satin Cream Maker: 1%
  • Shea Butter (Ultra Soft): 5%
  • Fractionated Coconut Oil: 3%
    Combine ingredients in Phase B. Heat gently to 70-75°C until Shea Butter is completely melted and ingredients are combined.

• Phase C (Silicone/Zinc Oxide Phase):

  • Cyclomethicone / Cyclopentasiloxane: 1%
  • Zinc Oxide 200nm EasyDisperse: 10%
    In a separate container, combine ingredients in Phase C. Mix thoroughly using a mortar and pestle or a small grinder if necessary to ensure the Zinc Oxide is fully dispersed and there are no clumps.

• Phase D (Cool Down Phase):

  • Perfume: Just Milk: 0.5%
  • Phenoxyethanol SA: 1%

Steps:

1. Heat Phase A and Phase B to 70-75°C.
2. Slowly add Phase B to Phase A while mixing continuously and vigorously with a homogenizer or stick blender. Maintain high shear mixing for 3-5 minutes to create a stable emulsion. Continue mixing gently while the emulsion cools.
3. Once the emulsion has cooled to below 50°C, add the prepared Phase C dispersion. Mix thoroughly to ensure the Zinc Oxide is evenly incorporated throughout the cream.
4. Continue cooling the mixture with gentle stirring. Once the temperature is below 40°C, add the ingredients from Phase D and mix until uniform.
5. Check the pH of the final product and adjust if necessary (many skin actives work best in a slightly acidic range, e.g., pH 5.0-6.0).
6. Package the cream in a suitable container.

Important Notes:

• Always follow good manufacturing practices (GMP) and ensure all equipment and containers are clean and sanitized.
• This is a suggested formulation. Small-scale testing is highly recommended to evaluate the texture, stability, and skin feel before making a larger batch.
• The effectiveness of the sun protection depends on accurate measurement, proper dispersion of Zinc Oxide, and application amount.
