Creating a Liquid Primer-Foundation from Mineral Powder

To convert a mineral makeup powder formula into a liquid foundation with added pore coverage and a primer effect, you can indeed add emollients like LipidSoft and silicones. Here's a guide:

1. Liquid Base

As you mentioned, adding an emollient like LipidSoft C1215 is the correct approach to turn the powder into a liquid. You will add enough of this liquid base until you achieve the desired liquid consistency for your foundation.

2. Adding Pore Coverage and Primer Effect

To enhance pore coverage and provide a primer-like effect, you can incorporate specific silicones or blurring powders into the liquid base. Suitable options include:

• Silicone Gel (Ultra Clear, Super Silky): This is a liquid silicone gel that provides a soft, smooth, and light feel, and helps blur the skin. It's suitable for liquid foundation formulas.
• SiliSilk™ Powders: Various SiliSilk™ powders offer blurring effects. For liquid formulas that don't require significant thickening, consider SiliSilk™ 5L or SiliSilk™ 10L. If you need higher blurring and sebum absorption, SiliSilk™ 10M or SiliSilk™ 10H are good options.
• UltraBlur™: This is a specially processed silica powder designed for high skin blurring.

A typical usage rate for these blurring silicones or powders is between 1-10% of the total formula, depending on the desired level of pore blurring and texture modification.

3. Increasing Coverage

As the staff reply mentioned, increasing the amount of mineral powders, such as Talc Powder (Methicone Coated) or Mica Powder (Methicone Coated), can improve the overall coverage of the foundation. For good coverage in BB/CC creams, at least 20% powder content is often used, but you can adjust this percentage based on your desired coverage level.

4. Mixing Steps

The correct mixing method is to first combine your liquid ingredients (LipidSoft C1215 and any liquid silicone like Silicone Gel Ultra Clear). Then, gradually add your mineral powders (including Talc Powder or Mica Powder) and the chosen blurring powder (like SiliSilk or UltraBlur) to the liquid phase. Mix thoroughly to ensure all powders are evenly dispersed in the liquid base, creating a smooth liquid foundation.

By adjusting the ratio of the liquid base to the powders and incorporating a suitable blurring agent, you can effectively transform your mineral powder into a liquid primer-foundation with enhanced pore coverage.
