WITHOUT TITANIUM DIOXIDE

Quick Facts:

• Category: other
• Also Known As: Ohne Titandioxid, 이산화 티타늄 없음, Sans dioxyde de titane, Sin dióxido de titanio, Sem dióxido de titânio, 酸化チタン不使用, Senza biossido di titanio, Zonder titaniumdioxide

Proven Benefits At A Glance:

• Titanium dioxide (TiO2) is a white additive widely used in skincare and other products, but safety concerns are driving interest in alternatives
• Calcium carbonate is currently used as an alternative to TiO2 in white coatings, though it produces less whiteness
• New porous film technologies inspired by beetle scales can achieve high whiteness without TiO2 or pigments
• Research on TiO2 alternatives is still developing, with limited data on skincare applications specifically

Safety tier is a starting heuristic from regulatory status and comedogenic rating, not a dermatological verdict — see our Terms for the full disclaimer. Research confidence reflects how many real cited studies back this ingredient, not the strength of their findings.

🔬 The Science

Titanium dioxide has been a standard ingredient for creating white, opaque products in skincare and pharmaceuticals for decades. However, growing health concerns about TiO2 have motivated researchers to develop alternatives (2026 peer-reviewed research). #1: Calcium carbonate is the most common replacement currently in use for white coatings, but it delivers inferior whiteness compared to TiO2 (2026 research). #2: Scientists have developed a new approach using porous films made from polyvinyl alcohol (PVA) and polyethylene glycol (PEG)—polymers that create tiny air pockets within the film. These air pockets scatter light differently than solid materials, generating whiteness through a physical mechanism rather than chemical opacity.

The porous films achieved whiteness scores (measured on the CIELab scale) of 80 to 87, significantly higher than denser films using other plasticizers (2026 research). #3: The specific shape of calcium carbonate particles also matters: quasi-rhombohedral forms (a particular crystal shape) increased whiteness by 8.2% compared with spindle-shaped aggregates when used in the same porous structure (2026 research). The research suggests these bioinspired porous films represent a promising direction for TiO2-free white formulations in tablets and coatings. It’s important to note that the available research focuses on tablet coatings and pharmaceutical applications rather than skincare products specifically, so direct claims about skincare benefits should be considered preliminary.
