Cream Formulation: Mixing Time and pH for a Corrected Recipe
Question
Regarding the corrected cream formulation steps provided:
Phase A: Heat Macadamia Oil + Shea Butter to 60°C until Shea Butter melts. Cool to room temperature. Add Tocopheryl acetate (Vitamin E) and Light Cream Maker.
Phase B: In distilled water, add Vitamin B5, Hydro Protein, Vitamin B3, MOIST72, Phenoxyethanol. Dissolve in warm water at 40°C. Stir until dissolved. Add Glycerin when cool to room temperature.
After combining phase (A) and (B) and mixing until a cream forms, how long should the mixing take? Also, is it correct that pH adjustment to 5.5 is not needed as the formula will naturally have a slightly acidic pH?
Answer
Based on the corrected steps provided by the staff:
Mixing Procedure:
- Phase A: Heat Macadamia Oil and Shea Butter to 60°C until the Shea Butter is completely melted. Let it cool down to room temperature. Add Tocopheryl acetate (Vitamin E) and Light Cream Maker™ to this oil mixture.
- Phase B: In a separate beaker, add Distilled Water. Warm it to 40°C and add dl-Panthenol (Vitamin B5), Hydrolyzed Vegetable Protein (Hydro Protein), Niacinamide (Vitamin B3), MOIST72™, and Phenoxyethanol. Stir with a glass rod until everything is dissolved. Let it cool down to room temperature. Add Glycerin.
- Combine: Add Phase A to Phase B and mix until a homogeneous cream is formed.
Mixing Time:
The time it takes to form a cream after combining phases A and B depends on the quantity you are making and the mixing equipment used. Generally, you should mix continuously until the mixture becomes a uniform, creamy consistency. This might take a few minutes of steady stirring.
pH Adjustment:
According to the staff's response, pH adjustment is not necessary for this specific formula. The formula is expected to be slightly acidic on its own, which is suitable for the skin.
