Making White Cream with Light Cream Maker Despite Colored Extracts

Asked by: cram-croo On: October 23, 2014 Product Type: Cosmetics

Question

When using Light Cream Maker™ to formulate a cream that includes colored extracts like green tea extract (e.g., Hi-EGCG™), how can I achieve a white cream? Specifically, how should I incorporate white pigments like Titanium Dioxide and Pearl Mica into the formulation to counteract the color from the extract?

Answer

Green tea extract, especially the liquid form like Hi-EGCG™, does have a dark green-brown color which can affect the final color of your cream, making it appear darker or tinted. Pure-EGCG™ is a light powder, so it is less likely to significantly darken the formula, but it has low solubility in water.

Yes, you can definitely make a white cream even when using Light Cream Maker™ by incorporating white pigments. The most common white pigments used in cosmetics are Titanium Dioxide and Pearl Mica, as mentioned in the previous reply.

Here's how they work and how to use them:

  • Titanium Dioxide: This provides opaque white color and coverage. It's commonly used in makeup products to lighten the shade or provide a tone-up effect. For use in creams, you would typically use pigment-grade Titanium Dioxide (like Titanium Dioxide 250nm Pigment or Titanium Dioxide 300nm Pigment) which needs to be dispersed in the water phase of your formulation. Alternatively, a pre-dispersed liquid form like WaterMix™ White (Titanium Dioxide 60%, Water-Dispersible Liquid) is easier to incorporate into water-based formulas like those made with Light Cream Maker™. The usage rate depends on the desired level of whiteness and coverage, typically ranging from 1% to 25%. Be mindful that using a high percentage can leave a white cast on the skin, as noted in the previous reply.
  • Pearl Mica: Mica powders, such as White Pearl Mica or Silver Pearl Mica, provide a white appearance with a pearlescent or shimmering effect rather than opaque coverage. They reflect light, making the cream look brighter and potentially helping to visually minimize imperfections. Mica is typically dispersed in the oil or silicone phase of a formulation. Since Light Cream Maker™ can emulsify oil and silicone, you can disperse the Mica in a small amount of oil or silicone suitable for your formula before adding it to the cream. Usage rates for Mica in creams are generally lower, often in the range of 1% to 3%, depending on the desired shimmer intensity.

To achieve a white cream using Light Cream Maker™:

  1. Formulate your cream base using Light Cream Maker™.
  2. Prepare your white pigment:
    • If using Titanium Dioxide powder, ensure it is well dispersed in the water phase before combining with the oil phase containing Light Cream Maker™.
    • If using WaterMix™ White liquid, you can add it directly to the water phase.
    • If using Pearl Mica, disperse it thoroughly in a small amount of oil or silicone suitable for your formula before adding it to the cream.
  3. Add the prepared pigment dispersion to your cream base and mix well until the desired white color and consistency are achieved.

The amount of pigment needed will depend on the concentration and color intensity of your green tea extract and the desired final whiteness. You will need to experiment with the percentages to find the right balance.
