• Product details: Mascara is a cosmetic product that can thicken, lengthen, color, and curl eyelashes. It is available in different formulations, including waterproof and non-waterproof. Some mascaras are vegan, cruelty-free, and free from parabens, alcohol, fragrance, and microplastic particles.

• Positive: Mascara can enhance the appearance of eyelashes by making them look longer, thicker, and darker. It can also help to curl the lashes and make the eyes look more open and awake.

• Negative: Some mascaras may contain harmful ingredients such as parabens, formaldehyde, and mercury-based elements. These ingredients can be absorbed through the skin and considered toxic to the body. Some emulsifiers used in mascara formulations, such as triethanolamine and stearic acid, can also have negative effects on the body and the environment.

Mascara formulations typically include water as a carrier, volatile solvents, LGN emulsifiers, waxes, pigments, film formers/waterproofing polymers, humectants, preservatives/potentiators, dispersing agents, emulsion stabilizers, and lash lengthening fibers/volumizing powders. The most common pigments used in mascara formulations are black, yellow, and red iron oxides, while other pigments include ultramarines, titanium dioxide, carmine, chromium oxide greens, chromium hydroxide green, manganese violet, ferric ferrocyanide, and D&C Black No2 (carbon black) . Some mascaras are made with clean ingredients, such as plant-derived materials, and are cruelty-free and dermatologist-tested. Waterproof mascaras usually include a volatile organic solvent as the main ingredient, such as isododecane.
