BB/CC Cream Texture and Stability Issue After Ingredient Change
คำถาม
I made a BB/CC cream formulation based on a previous formula, but I replaced the original base (Aloe Vera Gel (Heavy) at 69.2%) with 30% Aloe Vera Extract and adjusted the water. The resulting cream has a non-smooth, grainy texture with white, clear particles. What caused this issue, and how can I achieve a smooth, stable texture?
คำตอบ
Based on your description and the formula provided, the issue with your BB/CC cream not being smooth and having white, clear particles is likely due to the significant change you made to the base ingredient and the resulting imbalance in the formula's emulsification system.
The original formula used "Aloe Vera Gel (Heavy)" as the base, which is a pre-made gel containing purified water, Aloe Vera Extract, Vitamin B5, Pro Polymer (a gel maker/thickener), Allantoin, and a preservative. This base provides structure and helps emulsify the other ingredients.
You replaced 69.2% of this complex gel base with 30% of "Aloe Vera Extract". While the original gel base contains Aloe Vera Extract, it also contains other crucial components like thickeners and a high percentage of water (92.2% in the base itself). By replacing the entire base with just the extract, you significantly altered the water content and removed the primary thickening and emulsifying system provided by the original gel base. This imbalance prevents the oil phase (containing Titanium Dioxide, Silk Mica Powder, and Dimethicone Light) from properly dispersing and emulsifying into the water phase, leading to separation and the grainy, non-uniform texture you observed. The white particles are likely poorly dispersed pigments and oils.
The staff's revised formula and steps address this issue by providing a proper emulsification system designed for the ingredients used. Key changes include:
- Increased Emulsifier: The amount of Luxury Cream Maker is significantly increased from 0.3% to 4%. Luxury Cream Maker is an emulsifier and thickener that helps bind the oil and water phases together to form a stable cream.
- Corrected Aloe Vera Extract Percentage: The Aloe Vera Extract is used at a more appropriate level (1%) for an extract, rather than attempting to replace a large percentage of the base with it.
- Defined Emulsification Process: The staff's steps outline a standard method for creating an emulsion by preparing separate oil and water phases and then carefully combining them with mixing and heating. This process is essential for achieving a smooth, uniform cream texture.
To achieve a smooth texture, please follow the staff's recommended formula and mixing steps precisely:
Revised BB/CC Cream Formula:
- Titanium Dioxide Nano EasyDisperse: 3.5%
- Silk Mica Powder: 10%
- Dimethicone Light: 17%
- Luxury Cream Maker: 4%
- Aloe Vera Extract: 1%
- Vitamin B5 (Panthenol): 1%
- Phenoxyethanol SA: 1%
- Purified Water: Remaining percentage
Revised Mixing Steps:
- Combine Titanium Dioxide Nano EasyDisperse, Silk Mica Powder, Dimethicone Light, and Luxury Cream Maker. Mix or blend these ingredients together with heat at 60-70°C until you get a smooth, uniform texture. This is your oil phase.
- In a separate container, combine Aloe Vera Extract, Vitamin B5 (Panthenol), Phenoxyethanol SA, and Purified Water. Mix until all ingredients are dissolved and the liquid is clear. Warm this water phase slightly to 50-60°C.
- Slowly add the water phase into the oil phase little by little. Mix well after each small addition before adding more of the water phase. Continue mixing until all of the water phase has been incorporated and you achieve a smooth cream texture.
Following these steps and using the correct percentages of ingredients, especially the increased Luxury Cream Maker, will help ensure proper emulsification and result in a smooth, stable cream.
