Cream Thinning Issue with Silky Serum Base Plus

Based on the information for Silky Serum Base Plus (Face/Eye, Oil), the issue of your cream thinning after about two weeks can be caused by several factors, especially when adding other ingredients to the base.

Here are the potential causes and recommended solutions:

• Mixing Method: Silky Serum Base Plus requires a specific mixing method. Adding a large amount of water or water-based ingredients all at once can prevent the base from forming a stable gel structure. You should add water gradually, in small portions, stirring or blending well before adding more. Using a blender with appropriate speed can help achieve better homogeneity.
• Adding a Stabilizer: The instructions for Silky Serum Base Plus state that you should add 1-2% Magnesium Sulfate in the final step of mixing and blend it until it dissolves completely into the cream. This ingredient helps increase the stability of the formula and prevents separation, which could be the reason for the cream thinning over time.
• Ingredient Ratios: Check the proportion of water and oil you are adding. Silky Serum Base Plus can accommodate oils up to 30% of the total formula, and the formula should contain at least 60% water (70% is recommended for stability). If the oil ratio is too high, or the water ratio is too low, the formula may become unstable and thin out.
• Other Added Ingredients: Some ingredients you add might affect the stability of the base. Check if these ingredients are compatible with the base.
• Storage Conditions: The product should be stored at temperatures not exceeding 30 degrees Celsius and kept away from direct sunlight, as heat can impact the stability of the cream texture.

Summary of Recommendations:

1. Verify that you are using the correct mixing method by gradually adding water-based ingredients to the base.
2. Most importantly: Try adjusting your formula by adding 1-2% Magnesium Sulfate in the final mixing step and blend thoroughly.
3. Review the ratios of water and oil used to ensure they are within the recommended range for Silky Serum Base Plus (oil maximum 30%, water minimum 60-70%).

Adding Magnesium Sulfate is often the most effective way to solve the thinning issue for this type of base.
