Formula Review and Enhancement Suggestions

Thank you for submitting your lotion formula for review. You are looking for a lotion for both face and body use, targeting whitening, increased moisture, and a non-greasy texture, considering your skin type (normal face, slightly oily nose, dry and uneven body skin).

Based on the formula and the staff's response, the original formula had a compatibility issue between the emulsifier (Satin Cream Maker) and the electrolyte (Ammonium Lactate), which would prevent proper emulsification.

Revised Formula Review

The staff has provided a revised formula and mixing method to resolve the emulsification problem. The revised formula includes:

• Ammonium Lactate (5%): Effective for moisturizing dry skin and improving texture. As noted by the staff, 5% might be high for normal facial skin. Using 2-2.5% for a single formula or applying a thinner layer on the face is recommended.
• Phenoxyethanol SA (1%): Acts as a preservative.
• GlucoBright™ (Acetyl glucosamine, 4%) and Safe-B3™ (Niacinamide, 4%): These are excellent whitening agents that work synergistically to reduce hyperpigmentation and improve skin tone.
• Satin Cream Maker™ (1.5%), Clay Thick Ready (15%), and Xanthan Gum (0.5%): This combination is designed to create a stable emulsion with a non-greasy feel, addressing the texture requirement.
• Grape Seed Oil (Refined, 5%): Provides light nourishment and moisture.

The revised formula is well-structured to address the technical challenges and includes effective ingredients for your goals. The texture should be non-greasy, and the combination of Ammonium Lactate, Acetyl glucosamine, and Niacinamide should provide good moisturizing and whitening benefits.

Suggestions for Additional Whitening Ingredients

To further enhance the whitening effect, adding Alpha-Arbutin is a great suggestion, as mentioned by another user. Alpha-Arbutin works by inhibiting melanin production at a different step than Niacinamide and Acetyl glucosamine, offering a complementary mechanism for improved results. A typical concentration for Alpha-Arbutin is 0.2-2%.

Adding Alpha-Arbutin to the revised formula would likely boost its effectiveness in achieving a brighter and more even skin tone.
