Hello,
Regarding your request for a non-greasy, easily absorbed, moisturizing lotion formulation with a strong, long-lasting fragrance similar to Bath & Body Works, the staff has provided an adjusted formula and detailed instructions.
Here is the recommended formula:
- EDTA: 0.2%
- Niacinamide: 5%
- Glycerin: 5%
- Shea Butter: 5%
- Cyclomethicone: 10%
- Cetearyl Alcohol: 5%
- Activated Resorcinol: 1%
- Phenoxyethanol: 1%
- Fragrance: 5%
- Last-Fix: 5%
- Milk Lotion Maker: 3%
- Water: Remaining portion
Mixing Instructions:
- Combine Shea Butter, Cyclomethicone, Cetearyl Alcohol, Last-Fix, and Milk Lotion Maker. Heat this oil phase mixture to 80°C until fully dissolved.
- Combine EDTA, Niacinamide, Glycerin, and Water. Heat this water phase mixture to 70-80°C.
- Slowly add the heated water phase to the heated oil phase while continuously stirring or blending. Blend at low speed until the mixture cools down to below 50°C.
- Once the mixture is below 50°C, add Activated Resorcinol, Phenoxyethanol, and Fragrance. Blend for at least 5 minutes to ensure Activated Resorcinol is fully dissolved.
For fragrance, the formula includes 5% fragrance and 5% Last-Fix to help with longevity. The staff previously mentioned that you could try 2-3% fragrance and increase if needed, but advised patch testing for higher concentrations. The current formula uses 5%.
Please note that I cannot see the attached picture, so I cannot comment on how this formula's texture compares to the image.
Thank you.
