Eyeshadow products must possess the following characteristics:

They should be easy to apply and blend into an even tone, with good adhesion;

The color should remain stable and not alter due to exposure to sunlight, sebum, or sweat;

The applied film should not break down in the presence of sweat or sebum, ensuring long-lasting wear;

They must be safe for use, given their application in the delicate area around the eyes.

As cosmetics applied to the eyelids and corners of the eyes, eyeshadows create shadows and color contrasts that enhance the eyes' dimensionality and beauty, making them look more captivating. Eyeshadows offer the widest color range among eye cosmetics-including blues, greens, browns, tans, and purples, alongside black, white, red, and yellow for blending-with shades evolving according to fashion trends and individual needs regarding skin tone, clothing, seasons, and occasions. High coverage is not a requirement for eyeshadows; instead, quality standards focus on ease of application, a non-greasy finish, and resistance to smudging or wearing off due to sweat. To ensure product safety, strict hygiene supervision and management are essential throughout production-covering raw material selection, manufacturing processes, and packaging design. Regarding raw materials, the sterilization of powders is crucial, with radiation sterilization serving as a convenient method. Individuals with sensitive skin around the eyes should exercise caution when using these products.
