Question

Based on the context of formulating a liquid light-diffusing base with a dewy finish (likely a Water-in-Silicone or Water-in-Oil emulsion), can Pearl Red Mica, Pearl Blue Mica, and SoftGlow™ (Alumina) be combined in this type of formulation?

Answer

This formula for a liquid light-diffusing base with a dewy finish appears to be a Water-in-Silicone or Water-in-Oil emulsion, characterized by a high content of silicones and emollients.

Key components and their functions:

  • Silicones (Cyclopentasiloxane, Cyclohexasiloxane, Cyclomethicone, Dimethicone/Vinyl Dimethicone Crosspolymer, PEG/PPG-19/19 Dimethicone, Cetyl PEG/PPG-10/1 Dimethicone): These form the base structure, providing a lightweight, non-greasy feel, slip, and helping to suspend pigments. Dimethicone/Vinyl Dimethicone Crosspolymer can also offer a blurring effect. Cetyl PEG/PPG-10/1 Dimethicone and PEG/PPG-19/19 Dimethicone act as emulsifiers.
  • Emollients (Caprylic/capric triglyceride, Diisostearyl Malate): These contribute to the smooth texture and skin feel.
  • Humectants (Butylene Glycol, Sodium Hyaluronate): Provide hydration, contributing to the "dewy" look.
  • Thickeners/Stabilizers (Ozokerite, Magnesium Aluminum Silicate, Sodium Chloride): Help stabilize the emulsion and adjust viscosity.
  • Effect Pigments/Powders (Pearl Powder, Silica, and likely others): These are crucial for the light-diffusing, shimmer, and glow effect. As the staff mentioned, ingredients like Titanium Dioxide (for brightening), Bismuth Oxychloride (for glossiness/glow), and Synthetic Fluorphlogopite (as a glowy base) are commonly used to achieve this look. Pearl Powder in the ingredient list also contributes to shimmer. Silica can provide a soft-focus effect and help absorb oil.
  • Plant Extracts: Numerous extracts are included, likely for added skin benefits such as soothing, antioxidant, or conditioning properties.
  • Preservative (Phenoxyethanol): Ensures product stability and safety.
  • Fragrance: Provides scent.

To achieve the dewy, light-diffusing effect with fine shimmer and glow, the combination of silicones for texture, humectants for dewiness, and specific effect pigments like Pearl Powder, Titanium Dioxide, Bismuth Oxychloride, and Synthetic Fluorphlogopite is key.

Regarding your question about combining Pearl Red Mica, Pearl Blue Mica, and SoftGlow™ (Alumina): Yes, as confirmed by the staff, these can be combined. Pearl Mica pigments provide color and shimmer/pearlescence, while SoftGlow™ (Alumina) is an effect pigment that enhances glow and smoothness. Combining them allows for adjusting the color tone and enhancing the overall luminous effect of the base.
