Formulation Check for Whitening Face Cream

Yes, the ingredients you listed are suitable for creating a whitening face cream.

• Safe-B3 (Niacinamide) 5% and n-acetyl glucosamine (GlucoBright™) 4% are effective active ingredients commonly used together for skin brightening and reducing dark spots. The concentrations you've chosen are within typical effective ranges.
• Light Cream Maker™ 1% is likely used as an emulsifier or thickener to create the cream texture.
• Ethoxydiglycol 1% acts as a solvent and helps with ingredient penetration.
• Water is the base.

However, for a complete and stable formulation, you would typically need to add:

• A preservative to prevent microbial growth, as the formula contains water.
• A pH adjuster to ensure the final product has a skin-friendly pH (usually between 5.0-6.0).
• You might also consider adding humectants or emollients for better hydration and skin feel, depending on your preference.

The combination of Niacinamide and N-acetyl glucosamine is a well-regarded pairing for whitening effects.
