Bright Blue Tone-Up Product: Pigment Selection for Easy Oil Dispersion

For creating a bright blue tone-up product similar to Jung Saem Mool Skin Setting Tone Filter Base, and considering your need for easy dispersion in oil without grinding, we recommend Ultramarine Blue EasyMix™.

Here's why:

• Ultramarine Blue EasyMix™ (CI77019, CI77007) is specifically designed for exceptional ease of dispersion. It is coated with Methicone, allowing it to mix smoothly and provide a consistent color tone even with simple stirring, eliminating the need for grinding. It disperses well in both silicone and oil, making it ideal for your oil-containing formula. Ultramarine Blue is also known for its vibrant blue shade, which can help achieve the bright tone you desire.
• FD&C Blue No.1 Lake (Brilliant Blue) (CI42090) is another excellent option for a bright blue. It is an organic pigment that can be dispersed in oil, making it suitable for your formulation. While it disperses in oil, the EasyMix™ feature of Ultramarine Blue offers a superior advantage for ease of mixing without grinding.
• FD&C Blue No.2 Lake (CI 73015) is also an oil-dispersible organic blue pigment. However, it has a regulatory note stating it is "Not allowed to be used around the eyes, such as eye shadow." While a tone-up product is generally for the face, this restriction might be a consideration for broad facial application.

Given your specific requirement for easy dispersion without grinding, Ultramarine Blue EasyMix™ stands out as the most suitable choice. If you are looking for a slightly different bright blue hue, FD&C Blue No.1 Lake (Brilliant Blue) would be a good alternative, though it may require more effort in dispersion compared to the EasyMix™ variant.
