Need for Liquid/Binders in Pressed Powder/Blush

For pressed powder or pressed blush formulations, it is generally necessary to include liquid or semi-solid ingredients that act as binders. Simply using only dry powders and pressing them usually results in a product that does not hold together well, breaks easily, and is not durable.

These binders help the powder particles adhere to each other, allowing them to be pressed into a solid cake and providing strength to the product so it doesn't crumble easily during use. There are various types of binders commonly used, such as various oils (e.g., Mineral Oil, Jojoba Oil), silicones (e.g., Dimethicone), or certain types of waxes.

Therefore, to achieve a good quality pressed powder or blush that does not break easily and stays cohesive, it is necessary to include liquid ingredients or binders in the formulation.
