Adjusting BB Cream Shade and Understanding Titanium Dioxide Functions
Question
The color of the BB cream using Iron oxides ID: 31475, 31473 looks too dark.
- If I want to adjust the tone to be lighter, which product would you recommend?
- And for the "white oxide," is it added only for color adjustment, or does it also help the color adhere to the skin?
Because I would like to maintain the same percentage of whiteness that sticks to the skin.
Answer
To lighten the tone of your BB cream while maintaining high coverage and skin adhesion, it is recommended to use a Coated Titanium Dioxide that matches the coating of your current Iron Oxides.
1. Recommended Products for Lightening the Tone
Since your current pigments are coated with Triethoxycaprylylsilane for better adhesion and water resistance, you should use a Titanium Dioxide with the same coating for optimal compatibility and ease of dispersion:
- Titanium Dioxide 400nm WaterProof™ (Super Coverage): This grade provides very high opacity. It is ideal if you want to lighten the shade while maintaining maximum "whiteness" and coverage on the skin.
- Titanium Dioxide 300nm SilkTouch™ (Triethoxycaprylylsilane Treated): This grade offers a silky feel and natural brightening effect, making it suitable for formulas where a smooth texture is a priority.
2. The Role of White Oxide (Titanium Dioxide)
Titanium Dioxide serves two primary purposes in your formulation:
- Color Adjustment: It acts as the white base. To achieve a lighter shade, you simply increase the ratio of Titanium Dioxide relative to the darker Iron Oxides.
- Coverage & Adhesion:
- Coverage: The pigment particles themselves provide the opacity needed to hide imperfections.
- Adhesion: The long-wear and "sticking" property is primarily provided by the Triethoxycaprylylsilane coating. By using a coated version, you ensure the product remains waterproof and adheres well to the skin, consistent with the performance of your current iron oxides.
Summary: To lighten the shade while keeping the same level of coverage, increase the dosage of Titanium Dioxide 400nm WaterProof™ in your formulation. This will dilute the intensity of the red and yellow oxides while providing a strong white base that stays on the skin.
