Lotion formula review for very dry skin and whitening (with ingredients)

Here is a review of your lotion formulation for very dry skin with whitening properties.

Based on the ingredients and their typical properties, this formulation appears compatible and well-suited for targeting both intense moisturization and skin brightening.

Here's a breakdown:

• Oil Phase: The combination of Sweet Almond Oil, Shea Butter, Horse Oil, and Fractionated Coconut Oil provides a rich blend of emollients and fatty acids, excellent for nourishing and softening very dry skin. Vitamin E adds antioxidant benefits and further supports skin conditioning.
• Water Phase: This phase contains a strong lineup of humectants and whitening agents. DI Water and EDTA are standard base ingredients. Safe-B3 (Niacinamide), GlucoBright (Acetyl Glucosamine), and Z-White (Zinc Glycinate) work through different mechanisms to target hyperpigmentation and improve skin tone. MOIST24 and Ammonium Lactate are powerful humectants that draw moisture into the skin, with Ammonium Lactate also offering exfoliating benefits at higher concentrations (your 5% usage is appropriate for moisturization and gentle exfoliation). VersaMoist acts as a penetration enhancer and additional moisturizer. Mild Preserved Eco provides preservation for the formula.
• Emulsification: You are using Silk Lotion Maker (Bis-PEG/PPG-16/16 PEG/PPG16/16 Dimethicone) as the emulsifier. According to its description, Silk Lotion Maker is suitable for cold-process mixing, meaning you can incorporate it by hand mixing without needing to heat the phases separately. This makes it a good choice if you don't have a homogenizer or high-shear mixer. It is designed to create a soft and smooth texture while minimizing greasiness.

Compatibility and Suitability:

• All the ingredients listed are generally compatible with each other in a lotion formulation.
• The percentages used are within the recommended ranges for the ingredients to provide significant moisturizing and whitening effects.
• The combination of Niacinamide and Acetyl Glucosamine (Safe-B3 and GlucoBright) is a well-researched pairing known for synergistic whitening effects.
• Ammonium Lactate at 5% is effective for moisturization and can help improve skin texture, which complements the rich oil phase.
• Silk Lotion Maker is indeed suitable for hand mixing as it works via a cold process. You can mix the oil phase ingredients with the emulsifier, then gradually add the water phase while continuously stirring by hand until an emulsion forms. Adding a small amount of a thickener or gel maker (like Carbomer or Xanthan Gum, though not listed in your formula) in the water phase can sometimes help stabilize hand-mixed emulsions, but Silk Lotion Maker is designed to be quite robust on its own.

Your formula seems well-constructed for your stated goals of intense moisturization and whitening for very dry skin, and the chosen emulsifier is suitable for hand mixing.
