Whitening and Moisturizing Lotion Formulation

Here is a suggested formulation for a whitening and moisturizing lotion using the ingredients you provided. This formula aims to combine the skin brightening effects of multiple actives with strong hydration.

Important Considerations:

• This is a sample formulation. Adjustments may be needed based on desired texture and stability.
• Always perform a small test batch before making a large quantity.
• Ensure accurate weighing of all ingredients.
• Maintain good manufacturing practices and hygiene.
• The final pH of the lotion should be adjusted to 4.5-5.5 for optimal stability and efficacy of the whitening agents.
• Protect the finished product from light by using opaque packaging.
• Sun protection is crucial when using whitening products. An SPF ingredient like SPF Protect Ultra should be included in a daytime lotion, but the specific usage rate for SPF Protect Ultra is not provided here.

Ingredients:

• Water: 50.3%
• Disodium EDTA: 0.2%
• Tranexamic Acid (Trans-White): 3.0%
• Oxyresveratrol: 5.0%
• White Cumin 2x: 3.0%
• Moist 24: 8.0%

Instructions:

1. Water Phase: In a beaker, combine Water and Disodium EDTA. Stir until dissolved. Add Tranexamic Acid, Oxyresveratrol, White Cumin 2x, Moist 24, and Allantoin. Stir to disperse/dissolve. Add Water-Film and blend with a high-shear blender for at least 15 minutes until fully dissolved and the water phase is slightly thickened.
2. Oil Phase: In a separate beaker, combine Soft Cream Maker and LipidSoft Lite. Heat this mixture to 60-70°C and stir until Soft Cream Maker is completely melted.
3. Emulsification: Slowly add the Water Phase to the heated Oil Phase while stirring continuously with a mixer or homogenizer. Maintain stirring until the emulsion is formed and the mixture begins to cool.
4. Cooling Phase: Continue stirring the lotion as it cools down. Once the temperature is below 40°C, add Activated Resorcinol, Sym-White, Perfect-C, Mild Preserved Eco, and Fragrance. Stir until uniformly mixed.
5. pH Adjustment: Check the pH of the final lotion. If necessary, adjust the pH to 4.5-5.5 using a suitable acid (e.g., Lactic Acid, Citric Acid) or base (e.g., Triethanolamine).
6. Packaging: Package the finished lotion in opaque containers to protect the light-sensitive ingredients.

This formulation provides multiple pathways for skin brightening through ingredients like Oxyresveratrol, White Cumin 2x, Sym-White, Activated Resorcinol, and Tranexamic Acid, while Moist 24, Water-Film, and Allantoin contribute to skin hydration and a comfortable feel. LipidSoft Lite provides a light, non-greasy emollient feel, and Soft Cream Maker creates the lotion texture. Disodium EDTA helps maintain stability, and Mild Preserved Eco provides preservation.
