3. Pigment
Gives color to Lipstick. These pigments are often hydrophobic to ensure long-lasting lip color and keep the color intense, not fading when exposed to water or humidity. For example, carmine and iron oxide.
4. Emollient
Softens and moisturizes lips, provides a comfortable feeling, and helps Lipstick glide more easily when applied. Some emollients are hydrophobic and form a protective layer on the lips. Examples include lanolin, shea butter, and aloe vera.
5. Solvent
Solvents help unite all the ingredients in Lipstick or are substances that can dissolve other substances. The solvents used in Lipstick are organic solvents such as ethyl acetate, propylene glycol, and alcohol. Solvents can also help keep Lipstick from drying out too much. Solvents are divided into 2: volatile solvents, which provide a calm and light sensation but can make the lips dry more quickly, and non-volatile solvents, which add softness and durability but can make the lips dry. The product feels heavy.
6. Conservative
Additional ingredients commonly used to prevent the growth of bacteria, fungi, and other microorganisms. A conservative attitude is essential in cosmetic products to maintain their safety and quality over the long term, mainly because they are often exposed to air and potential contaminants during use. For example, Parabens, Phenoxyethanol, Benzyl Alcohol, and Chlorphenesin.
Lipstick works by capturing and playing with light in fascinating ways. The colors in Lipstick come from pigments that grab onto specific light colors. So, the color you see on your lips is closely tied to the colors of light that bounce back. The interplay of absorbed and reflected light gives lipsticks their wide range of colors. The wavelength of the reflected light is critical in creating a unique and attractive shade on your lips. This dynamic interaction produces a visually appealing effect that is both charming and subtle.
Wavelength means measuring the distance between two consecutive peaks or troughs in a wave. In science and physics, we often use the Greek letter lambda () as a symbol to represent wavelength. This distance is typically measured in units of length, such as meters (m), centimeters (cm), or even nanometers (nm), depending on the scale of the wave. These units provide us with a standardized way of understanding the size or scale of wavelengths in different contexts.
