Overview of CI 77891 White titanium dioxide pigment powder in cosmetic
Metal powder is a common form of metal that has been processed into fine particles, ranging from a few micrometers to over 100 microns in diameter. It plays a crucial role in various industrial applications due to its unique properties and versatility.
Features of CI 77891 White titanium dioxide pigment powder in cosmetic
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of CI 77891 White titanium dioxide pigment powder in cosmetic
Titanium dioxide, also known as CI 77891, is a versatile and widely used pigment in the cosmetic industry due to its exceptional properties and benefits. This white pigment holds significant importance in various applications, from sunscreens to face powders, lipsticks, and even makeup foundations. The chemical formula for titanium dioxide is TiO2, which is derived from the oxide of titanium, a naturally abundant element.
One of the primary reasons for its popularity is its light-scattering ability, which gives it a brightening effect on the skin. When applied to cosmetic formulations, it acts as a natural sunscreen by reflecting ultraviolet (UV) rays, thus providing protection against sunburn and preventing premature aging caused by UV damage. It has a high SPF value, typically ranging from 15 to 50+, making it an essential ingredient in sunscreens and other sun-protective products.
In addition to its sun protection capabilities, titanium dioxide offers excellent coverage and opacity, enhancing the appearance of cosmetics. As a white pigment, it provides a smooth, matte finish, perfect for concealing imperfections and evening out skin tone. It is also known for its non-comedogenic nature, meaning it does not clog pores, making it suitable for all skin types, including sensitive ones.
Titanium dioxide’s superior light stability ensures that it maintains its whiteness and effectiveness over time, even when exposed to sunlight or heat. It is resistant to fading and yellowing, which is crucial for maintaining the integrity of cosmetic products’ color and performance. This property also contributes to its long-lasting wear, especially in formulations like eyeshadows and lipsticks.
Another advantage of CI 77891 is its compatibility with a wide range of cosmetic bases. It can be easily incorporated into creams, lotions, gels, and powders without affecting their texture or stability. Moreover, it is dermatologically tested and generally recognized as safe (GRAS), ensuring its suitability for use in personal care products.
However, it’s important to note that the particle size of titanium dioxide can impact its performance. Fine particles, often referred to as nano-titanium dioxide, provide better sun protection but may require additional safety precautions due to concerns surrounding their potential penetration into the skin. On the other hand, larger particles may provide more visible coverage but offer less protection against UV rays.
In summary, CI 77891 white titanium dioxide pigment powder is a cornerstone in the cosmetic industry due to its multifaceted benefits, including UV protection, coverage, and stability. Its widespread use is testament to its effectiveness and adaptability across various applications. As a result, it plays a crucial role in ensuring the quality, performance, and safety of countless beauty products available today.
