Titanium dioxide micronised 30 g

Optical SPF filter

Stabilized titanium dioxide made in Japan. With a particle size of approximately 0.21 μm, it creates an optically smoothing effect on the skin, improves formula sensitivity, and increases the stability of formulations. Ideal for BB creams, CC creams, primers, SPF bases, powders, and foundations with a natural skin finish.

What is Titanium Dioxide and what are the differences between its types read in the article “Titanium Dioxide in cosmetics”.

Types of UV Filters

UV filters in cosmetics are divided into chemical (organic) and physical (mineral). Chemical filters absorb UV radiation and convert it into thermal energy, while physical filters work primarily by reflecting and scattering light.

One of the main mineral UV filters is titanium dioxide (TiO₂), a photostable inorganic pigment widely used in SPF systems due to its effective protection against UVB and part of the UVA spectrum.

Titanium Dioxide Forms

Titanium dioxide is used in the cosmetics industry primarily in two crystalline modifications: anatase and rutile.

• Anatase is unstable and, when exposed to UV rays, can generate reactive oxygen species (ROS), accelerating oil oxidation, component degradation, and reducing formula stability. While it offers higher whiteness and opacity, it is actually used in cheaper formulations.
• Rutile is considered the standard for cosmetic and SPF systems. It is less prone to oxidation and is more compatible with oils, UV filters, and pigments. In decorative cosmetics, rutile TiO₂ provides softer light diffusion, a natural soft-focus effect, and a less pronounced "putty effect." It is used in premium SPF, BB/CC creams, primers, and foundations.

This type of titanium dioxide does not belong to the classic nano-range (usually 15-60 nm), but rather to titanium dioxide with a small particle size. This is an important technological difference:

• 20-60 nm - transparent sunscreen-grade UV filters
• 210 nm - optical pigment with a soft-focus effect
• 250-350+ nm - pigments with a high degree of coverage

The key nuance is that the particle size of 210 nm is the zone where titanium dioxide begins to act not only as a UV reflector, but as a full-fledged optical texture pigment. This is where the characteristic Japanese "tone-up skin effect" appears, rather than just a white covering pigment, like theatrical makeup.

Specific features of this SPF system

Aluminum hydroxide is an inert isolating coating. It reduces the formation of free radicals under UV rays, increases the photostability of the pigment, and protects the formula from oxidation and yellowing. Additionally, it improves pigment compatibility with emulsion systems and makes the optical finish more stable.

TMP - increases TiO₂ compatibility with oils, silicones, and esters. This coating improves pigment dispersion, reduces the dry, chalky feel, increases glide, and makes the coating thinner and more uniform. As a result, DT provides a softer, soft-focus effect and less pronounced whitening.

UV protection level of finely dispersed titanium dioxide:

• 2-3% - predicted SPF 2-5
• 5% - predicted SPF 5-7
• 10% - predicted SPF 10-18
• 15% - predicted SPF 15-20
• 20% - predicted SPF 20-25

However, SPF increases nonlinearly: after 15-20%, effectiveness begins to increase significantly more slowly; it is advisable to combine it with chemical filters.

Technological nuances of incorporation into formulations

This form of diesel fuel has a pronounced dependence on the quality of dispersion. The final SPF, whitening, sensory properties, and stability are determined not so much by the incorporation percentage as by the state of the particles in the finished system.

The main goal is to prevent secondary agglomeration. This is achieved by properly combining the oily phase (silicones + emollient cascade) and an optimal system (inverse emulsifiers, etc.). Low-stability, high-water systems without good dispersion should be avoided. Acrylate copolymers are the preferred choice for gelling the aqueous phase. They are most effective in hybrid SPF systems, in combination with Uvinul A Plus and Tinosorb S Lite Aqua.

Micronized titanium dioxide combines well with other fillers:

• silica
• boron nitride
• mica

Cosmetics that use titanium dioxide:

• Sunscreen emulsions
• BB cream
• CC cream
• Skin tint
• Foundations
• Soft-focus primers
• HD makeup products
• Cream correctors
• Concealers
• Compact powders
• Loose powders
• Finishing powders
• SPF sticks
• Cream blush and highlighters
