Lotion Formulation Review and Mixing Instructions

The lotion formula you've provided is a very good starting point for addressing both skin brightening and dryness, while aiming for a light, non-greasy feel. It contains key ingredients known for these benefits.

Formula Assessment

• Brightening: The formula includes Vitamin B3 (Niacinamide) at a good concentration (5%), which is well-known for its ability to improve skin tone, reduce hyperpigmentation, and strengthen the skin barrier. Roselle Extract also contributes to brightening through gentle exfoliation.
• Dry Skin: Ingredients like Allantoin, Glycerin, Jojoba Oil, and Aloe Vera Extract are excellent for providing moisture, soothing dry skin, and reducing irritation.
• Texture: Aristroflex AVC and Cyclopentasiloxane are included to help create a pleasant texture that is easier to absorb and less sticky. Soft Cream Maker™ acts as the primary emulsifier, contributing to the cream's structure.

Overall, this formula should effectively address your goals. The combination of moisturizing oils/extracts and texture enhancers is well-balanced.

Potential Adjustments

If you find the final texture is not quite as light and non-greasy as you desire, you might consider slightly reducing the percentage of Jojoba Oil (e.g., from 10% to 5-7%) or replacing a portion of it with a lighter emollient. However, try the formula as is first, as the Cyclopentasiloxane and Aristroflex AVC may provide sufficient lightness for your preference.

Mixing Instructions

Here is a step-by-step guide for mixing this lotion, based on the properties of the ingredients:

1. Phase A (Water Phase): Combine DI Water, Allantoin, Glycerin, Disodium EDTA, and Vitamin B3 in a heat-resistant container. Heat this phase to 70-75°C while stirring until all solids are dissolved.
2. Phase C (Oil Phase): In a separate heat-resistant container, combine Jojoba Oil, Cyclopentasiloxane, and Soft Cream Maker™. Heat this phase to 70-75°C, stirring until the Soft Cream Maker™ is fully melted and the oil phase is uniform.
3. Emulsification: Slowly pour the hot Phase C into the hot Phase A. Immediately begin using a high-shear mixer (such as a homogenizer or high-speed stirrer) to blend the two phases for 5-10 minutes. This is crucial for creating a stable emulsion.
4. Add Thickener: While continuing to mix the emulsion (you can reduce the speed slightly), gradually add Aristroflex AVC (Phase B) to the mixture. Continue mixing until the Aristroflex AVC is fully dispersed and the lotion starts to thicken.
5. Cool Down: Stop heating and continue mixing gently while the emulsion cools down to below 40°C.
6. Phase D (Cool Down Phase): Once the temperature is below 40°C, add the Aloe Vera Extract, Roselle Extract, Witch Hazel Extract, and Phenoxyethanol (Extra Pure). Mix thoroughly until all ingredients are evenly incorporated.
7. pH Adjustment: Check the pH of the lotion. For skin products, a pH between 5.0 and 6.0 is generally ideal. If needed, adjust the pH using a dilute solution of Citric Acid (to lower pH) or Triethanolamine (to raise pH), adding drop by drop and checking the pH after each addition.
8. Packaging: Once the lotion has cooled completely and the pH is adjusted, it is ready to be packaged.

This formula is well-designed to achieve your desired results. Happy formulating!
