What is Microcrystalline Wax?
Microcrystalline wax is a type of refined wax derived from the refining process of heavy crude oil. It consists of minute crystals, making it more flexible and tacky compared to other waxes like paraffin. Its melting point and levels of oil content can vary based on its specific formulation.
This wax is commonly used in cosmetics and personal care products for its emollient and tactile properties. It helps create a protective barrier on the skin, providing moisture retention and enhancing the texture of products. While there are no major health concerns, its safety as an ingredient in leave-on products continues to be evaluated.
When you see microcrystalline wax on a label, it often indicates its role in stabilizing or thickening the formulation, providing durability and consistency to the product.
Commonly found in: lip balms, lotions, creams, mascaras, stick deodorants
What to watch

Benefits
