Cream Separation and Thinning Issue: Adjusting Emulsifiers

Hello,

Regarding the issue of the cream becoming liquid and separating slightly after several days, as the staff previously informed, the cause is likely the relatively high proportion of the oil phase in the formula. This makes the 1% Satin Cream Maker, which acts as the emulsifier, unable to fully bind the water and oil phases.

To fix this issue and help thicken the cream and prevent separation, we recommend following the staff's advice:

Add Milk Lotion Maker at 4% to the oil phase. This will help enhance the effectiveness of Satin Cream Maker in emulsifying the water and oil phases together better. Please keep using Satin Cream Maker in the water phase as before.

Adding Milk Lotion Maker will help stabilize the formula, resulting in a thicker cream that does not separate.

Summary of Formula Adjustment:

• Oil Phase:
  • Coconut Oil 5%
  • Vitamin C Ester 8%
  • Shea Butter 3%
  • Dimethicone 5%
  • Kojic Acid 3%
  • Milk Lotion Maker 4% (Added)
• Water Phase:
  • Moist 24 8%
  • Satin Cream Maker 1%
  • Preservative
  • Water (Remaining)

Mixing Instructions (as previously recommended by staff):

1. Heat the entire oil phase until completely dissolved.
2. Blend the water phase until it forms a gel texture.
3. Heat the water phase to a temperature close to the oil phase.
4. Gradually add the liquid oil phase into the gelled water phase while continuously blending the water phase.
5. While the formula is cooling down, blend at a low speed to ensure the formula sets evenly throughout.

We hope this advice helps you achieve the desired lotion texture.
