Cream Primer Formulation for Makeup Longevity

Question

I want to create a cream or gel primer to help makeup last longer. I was considering using Magnesium Stearate, but the staff mentioned it might not be suitable in a cream base.

Cream Primer for Makeup Longevity

Regarding your question about using Magnesium Stearate in a cream primer for makeup longevity, Magnesium Stearate is primarily used in powder formulations to help with adhesion. However, incorporating it into a cream base will not provide the same long-lasting effect for your makeup.

To create a cream or gel primer that helps makeup, particularly powder components in products like BB cream, adhere better and last longer on the skin, formulators typically use ingredients like silicones or certain types of emollients from the LipidSoft™ range.

These ingredients form a thin layer on the skin that provides a smooth surface for makeup to grip onto, improving its wear time.

Suitable ingredients for this purpose include:

Silicones: Such as Dimethicone (Light, Low-Odor) or Silicone Blender.
LipidSoft™ Emollients: Options like LipidSoft™ CC or LipidSoft™ Lite are suitable.

Additionally, the type of powder used in your BB cream or other makeup also affects longevity. Powders that have been coated, such as Talc Powder (Methicone Coated) or Mica Powder (Methicone Coated), tend to adhere better to the skin or to the primer base compared to uncoated powders.
