Pressed Powder Formulation for Good Coverage and Oil Control

Creating a pressed powder with good coverage and oil control involves selecting the right combination of ingredients. Here are some key components commonly used:

Ingredients for Coverage

• Titanium Dioxide: Provides excellent coverage and contributes to UV protection. Look for types specifically designed for makeup with high coverage properties.
• Zinc Oxide: Offers coverage and also has oil-absorbing and soothing properties.
• Talc: A common base powder that provides slip and can contribute to coverage depending on particle size and treatment.
• Mica: Adds slip and can provide a smooth feel. Certain types can also contribute to coverage.
• Kaolin: A clay mineral that helps with coverage and oil absorption.

Ingredients for Oil Control

• Kaolin: Highly effective at absorbing excess oil.
• Silica: Can absorb oil and provide a mattifying effect. Different types offer varying levels of oil absorption and skin-blurring properties.

Ingredients for Pressing (Binding)

To press powder into a compact, binders are necessary to hold the powder together. Common binders include:

• Magnesium Stearate: A widely used binder in pressed powders that also improves adhesion and slip.
• Calcium Stearate: Another stearate that functions as a binder and anti-caking agent.

Notes on Pressing Powder

Pressing powder into a compact typically involves mixing the powder ingredients with a liquid binder (often an oil or silicone-based liquid) and then pressing the mixture under high pressure into the pan. The exact process and the amount of binder needed will depend on the specific ingredients used and the desired texture and hardness of the final product. Achieving a well-pressed powder requires careful formulation and proper equipment; it is not simply about putting loose powder into a compact.

By carefully selecting and balancing these types of ingredients, you can formulate a pressed powder that offers good coverage and helps control shine.
