Formulation Review and Mixing Method Correction

Here is a review of your formulation and mixing method for normal skin aiming for whitening and healthy-looking skin, incorporating the feedback provided:

Ingredient Compatibility and Suitability

The combination of Vitamin B3 (Niacinamide), N-Acetyl Glucosamine, and Activated Resorcinol is suitable for skin brightening and addressing dark spots. These ingredients are known to work well together for whitening purposes.

However, for normal skin, the combination of WaterLock and MOIST72 at the specified percentages (2% and 3% respectively) might result in a texture that feels too heavy or sticky, as noted in the feedback. Both ingredients provide significant moisture. You might consider reducing the percentage of one or both, or observing the texture and feel on your skin and adjusting in future batches if needed.

Phenoxyethanol is a standard preservative and is compatible with the other ingredients.

Mixing Method

The original mixing method is incorrect, specifically regarding Activated Resorcinol. Activated Resorcinol is oil-soluble, not water-soluble. Therefore, it needs to be dissolved in an oil phase before being incorporated into the water phase.

The suggested mixing method from the feedback is correct in principle:

1. Dissolve the Activated Resorcinol in a suitable oil, such as a LipidSoft type (e.g., LipidSoft C1215, LipidSoft Palm, or LipidSoft Lite) at the recommended usage rate (Activated Resorcinol is typically used at 1% in leave-on products, and LipidSoft can be used at 5% or more as a solvent/emollient). This forms the oil phase.
2. Mix the water-soluble ingredients (Vitamin B3, N-Acetyl Glucosamine, WaterLock, MOIST72) into the water phase.
3. If Satin Mousse is a thickener or emulsifier that needs to be dispersed in water, add it to the water phase and mix until uniform.
4. Slowly add the oil phase (containing Activated Resorcinol and LipidSoft) to the water phase while stirring or homogenizing to create an emulsion.
5. Once the emulsion is formed and uniform, add the preservative (Phenoxyethanol) and mix well.

This revised method ensures that the oil-soluble Activated Resorcinol is properly dissolved and dispersed in the final product.

• (Note: Information on "Satin Mousse" was not found in our product database, so its specific role and mixing instructions are based on typical formulation practices and your description.)*

In summary, the ingredients selected are appropriate for your goal, but you may need to adjust the percentages of WaterLock and MOIST72 for optimal texture on normal skin. The mixing method must be corrected to properly dissolve Activated Resorcinol in an oil phase before combining with the water phase.
