Titanium Dioxide (TiO2, CAS 13463-67-7) is an inorganic mineral compound and one of only two UV filters currently recognised as GRASE (Generally Recognized as Safe and Effective) under the US FDA OTC drug framework — the other being Zinc Oxide. It provides broad-spectrum UV protection — particularly strong in the UVB range and short-wave UVA (UVA II), with more limited long-wave UVA I coverage — primarily by absorbing and scattering UV energy while remaining on the skin surface. The SCCS has concluded that TiO2 (nano form) is safe as a UV filter at concentrations up to 25% for dermally applied cosmetic products — and confirms that TiO2 nanoparticles do not significantly penetrate intact human skin. SkinSenseDiary safety rating: 2/10 (low risk). Harmonised CLP classification: Carc. 2 H351 — this applies exclusively to the inhalation route and is not relevant to dermal application in cream, lotion, or stick sunscreens. The EU Cosmetics Regulation (Annex VI entry 27a) does not permit nano TiO2 in applications that may lead to inhalation exposure. No allergen flags. No conflicts. Also used as a colorant (CI 77891). Found in 14,565 products.
Titanium Dioxide (INCI: TITANIUM DIOXIDE, CAS 13463-67-7) is an inorganic mineral compound with the molecular formula TiO2 and a molecular weight of 79.87 Da. It is a bright white, odourless powder that occurs naturally in several crystal forms — rutile (the most stable and commonly used in cosmetics), anatase, and brookite. In cosmetics, titanium dioxide serves three functions: as a UV filter providing strong UVB and partial UVA protection, as a white pigment and opacifier (CI 77891) used extensively in foundations, concealers, and colour cosmetics, and as a viscosity modifier. It is one of only two UV filters classified as GRASE under the US FDA OTC drug framework — the other being Zinc Oxide — and has been used in commercial sunscreen products for decades.
As a mineral UV filter, titanium dioxide works primarily by absorbing and scattering UV radiation (with both mechanisms contributing significantly — the balance depends on particle size and crystal form) while remaining on the skin surface. The SCCS has confirmed through its opinion SCCS/1516/13 (and subsequent revisions) that TiO2 nanoparticles do not significantly penetrate intact human skin when applied dermally. Both nano and non-nano forms are considered safe for dermal application at concentrations up to 25%. Titanium dioxide is particularly effective at blocking UVB and short-wave UVA, making it a strong UVB protector often combined with Zinc Oxide (which provides better long-wave UVA coverage) for comprehensive broad-spectrum protection. Our database identifies titanium dioxide in 14,565 products — by far the most of any UV filter, reflecting its dual use as both sunscreen active and cosmetic pigment.
A critical safety distinction: titanium dioxide has a harmonised EU CLP classification of Carc. 2 (H351) — suspected of causing cancer. This classification applies exclusively to the inhalation route, based on animal studies showing lung tumour development after chronic inhalation of TiO2 dust in occupational settings. It does NOT apply to dermal (skin) application. The SCCS has explicitly confirmed that TiO2 is safe for dermally applied cosmetics. However, the EU Cosmetics Regulation (Annex VI entry 27a) does not permit nano TiO2 in applications that may lead to inhalation exposure (such as sprays and loose powders). Additionally, the SCCS Scientific Advice of 2024 raised concerns about the genotoxicity potential of most TiO2 grades used in oral cosmetic products (such as toothpaste and lipstick), concluding that available evidence is insufficient to exclude genotoxicity for most grades — an area of active regulatory review. No CIR Expert Panel safety assessment exists specifically for titanium dioxide, as it is primarily regulated as an OTC drug ingredient in the US.
Titanium dioxide provides broad-spectrum UV protection covering UVB (290–320 nm) and UVA II (320–340 nm), with some extension into UVA I. It is particularly strong in the UVB range, making it an excellent protector against sunburn. For comprehensive long-wave UVA I coverage, it is commonly paired with Zinc Oxide. As a single ingredient, titanium dioxide covers a wider UV range than most individual chemical filters, which typically address only a narrow portion of the spectrum.
Titanium dioxide works by absorbing and scattering UV radiation while remaining on the skin surface. The SCCS confirms that TiO2 nanoparticles do not significantly penetrate intact human skin — meaning negligible systemic absorption occurs from dermal application. This makes it a preferred choice for those concerned about systemic exposure from chemical UV filters (several of which have been detected in blood at levels exceeding proposed FDA safety thresholds, though without established clinical harm to date). Titanium dioxide provides immediate protection upon application with no wait time required.
Titanium dioxide is among the most well-tolerated UV filters available. The SCCS has noted it is a weak or non-sensitiser for skin applications. It is routinely recommended for sensitive, reactive, and compromised skin — including babies, individuals with rosacea or eczema, and post-procedure skin. Unlike some chemical UV filters that may cause stinging or photoallergic reactions, titanium dioxide rarely causes skin irritation. Its gentle profile makes it a staple ingredient in paediatric and dermatologist-recommended sunscreens.
Beyond UV protection, titanium dioxide is one of the most widely used white pigments in cosmetics (CI 77891). It provides opacity, coverage, and a brightening effect in foundations, BB creams, concealers, and tinted sunscreens. Its oil-absorbing properties can create a natural mattifying effect, beneficial for oily skin. Iron oxide pigments are commonly blended with TiO2 in tinted sunscreens to neutralise white cast while adding visible-light and blue-light protection.
Suitable for: All skin types, including sensitive, reactive, rosacea-prone, eczema-prone, and post-procedure skin. Recommended during pregnancy and nursing (non-spray formats). Suitable for babies and children. Particularly recommended for those who prefer mineral sunscreens or experience irritation from chemical UV filters. Available in both nano (less white cast) and non-nano formats.
Titanium Dioxide carries a SkinSenseDiary safety rating of 2/10 — low risk for dermal use. It is one of only two UV filters with GRASE recognition under the US FDA OTC drug framework. The SCCS has concluded it is safe at up to 25% for dermally applied cosmetic products, and confirms that TiO2 nanoparticles do not significantly penetrate intact human skin. The harmonised CLP classification (Carc. 2 H351) applies exclusively to inhalation and is not relevant to cream, lotion, or stick products. No allergen flags and zero conflicts. Key limitations: nano TiO2 must not be used in spray/aerosol products (EU Annex VI/27a), and oral use (toothpaste, lipstick) is under active genotoxicity review. Found in 14,565 products in our database.
Inhalation safety concern — H351 Carc. 2 (inhalation route only): Titanium dioxide has a harmonised EU CLP classification of Carc. 2 (H351) — suspected of causing cancer via inhalation. This is based on animal studies involving chronic inhalation of TiO2 dust in occupational settings. This classification does NOT apply to dermal (skin) application — when applied as a cream, lotion, or stick sunscreen, TiO2 particles remain on the skin surface and do not enter the lungs. The EU Cosmetics Regulation (Annex VI entry 27a) does not permit nano TiO2 in applications that may lead to inhalation exposure and applications that may cause lung exposure. If you use TiO2-based sunscreen, choose non-spray formats.
Oral use under review (toothpaste, lipstick): The SCCS Scientific Advice of 2024 concluded that available evidence is insufficient to exclude the genotoxicity potential of most TiO2 grades used in oral cosmetic products. Only two specific nano grades (RM09 and RM11) were cleared. This concern relates to products that may be ingested (toothpaste, lipstick) — it does not affect dermal-only sunscreens or colour cosmetics not applied to the lips. Note: the EU has already banned TiO2 as a food additive (E171) since 2022.
White cast: Like Zinc Oxide, titanium dioxide is a white mineral that can leave a visible white residue on the skin — particularly noticeable on darker skin tones. TiO2 generally produces a less intense white cast than ZnO at the same concentration. Nano forms produce less white cast than non-nano. Tinted formulations with iron oxides effectively eliminate white cast while adding visible-light protection. Modern formulation technology has significantly improved cosmetic elegance.
Nano vs non-nano — both safe on skin: The SCCS has confirmed that both nano and non-nano TiO2 are safe for dermal application at up to 25%. Neither form significantly penetrates intact human skin. The SCCS has noted that pigmentary (non-nano) grades may contain a sizeable proportion of nano-sized particles, blurring the traditional distinction. The key restriction is on inhalation exposure — nano TiO2 must not be used in products causing lung exposure.
Titanium dioxide is widely regarded as among the most well-tolerated UV filters during pregnancy and nursing when applied to the skin in non-spray formats. As a mineral UV filter, it remains on the skin surface — the SCCS confirms that TiO2 nanoparticles do not significantly penetrate intact human skin, meaning systemic exposure from dermal application is negligible. The harmonised CLP classification (Carc. 2 H351) applies exclusively to inhalation and is not relevant to creams, lotions, or stick sunscreens. TiO2 has no harmonised GHS reproductive or developmental toxicity codes (no H361d, no H362). Titanium dioxide sunscreens (non-spray) are routinely recommended by dermatologists and obstetricians during pregnancy, particularly as an alternative to chemical UV filters — some of which have raised concerns about endocrine activity. Both nano and non-nano forms are considered safe for dermal application during pregnancy. Avoid spray or loose powder TiO2 products during pregnancy as a precaution. Consult your healthcare provider for individualised advice.
After cleansing, toning, applying serums, and moisturising, apply titanium dioxide sunscreen as the final step of your morning skincare routine. Sunscreen should always be the last skincare product applied (before makeup). Titanium dioxide provides immediate protection upon application — unlike some chemical sunscreens, there is no 15–20 minute wait time. Many TiO2 sunscreens double as makeup primers due to their mattifying properties.
Most people apply far too little sunscreen. For the face alone, use approximately two finger-lengths of product (about 1/4 teaspoon or 1.25 ml). Apply evenly to the face, ears, and neck. For the entire body, approximately 35 ml (about 7 teaspoons) is needed for full coverage. Insufficient application dramatically reduces the effective SPF. Mineral sunscreens like TiO2 can feel thicker than chemical formulations — ensure even, thorough coverage.
No sunscreen provides all-day protection from a single application. Reapply every 2 hours during prolonged sun exposure, and immediately after swimming, heavy sweating, or towel-drying. For office workers with minimal sun exposure, a morning application with a midday touch-up is generally sufficient. Pressed powder TiO2 sunscreens can be convenient for reapplication over makeup without disturbing your look.
Under the EU Cosmetics Regulation, nano titanium dioxide is not permitted in applications that may lead to inhalation exposure. Choose cream, lotion, fluid, tinted, stick, or pressed powder formats. Do not use loose powder or aerosol spray TiO2 products. If white cast is a concern, try tinted formulations or nano TiO2 in cream/fluid formats. For comprehensive protection, look for products combining TiO2 with Zinc Oxide for comprehensive UVA + UVB coverage.
Combined TiO2 and ZnO formulation for the broadest mineral UV coverage. TiO2 excels at UVB, ZnO at UVA I. Best for sensitive skin, babies, and during pregnancy. May have white cast. SPF 30–50+ available.
TiO2 sunscreen with iron oxide tints that eliminate white cast and provide light coverage. Iron oxides also protect against visible light and blue light. Excellent for daily wear under or instead of makeup. Many double as BB creams or tinted moisturisers.
Combines titanium dioxide with chemical UV filters for better cosmetic elegance while maintaining broad-spectrum coverage. Lighter texture, less white cast. Good balance of protection and wearability. Not suitable if you want to avoid chemical filters entirely.
The classic mineral sunscreen combination. TiO2 provides strong UVB and short-wave UVA protection; ZnO provides superior long-wave UVA I protection. Together they deliver comprehensive broad-spectrum coverage without any chemical filters. Most mineral-only sunscreens use both ingredients.
An excellent pairing. Niacinamide strengthens the skin barrier, regulates sebum, and has brightening and anti-inflammatory effects — all complementing mineral sunscreen. Neither ingredient interacts negatively with the other. Apply niacinamide serum first, then TiO2 sunscreen on top.
Retinol increases UV sensitivity, making daily sunscreen essential. Titanium dioxide is an ideal sunscreen partner for retinol users — it provides immediate, broad-spectrum protection with minimal skin penetration. Use retinol in the evening, TiO2 sunscreen in the morning.
L-ascorbic acid serums with a pH below 3.5 may theoretically affect titanium dioxide stability, though in practice most well-formulated products coexist without issues. Apply vitamin C serum first, wait 10–15 minutes for absorption and pH neutralisation, then apply TiO2 sunscreen.
If using glycolic acid, lactic acid, or salicylic acid in the morning, TiO2 sunscreen is a good protective partner — these exfoliants increase UV sensitivity. However, some acid products may destabilise mineral sunscreen formulations. Apply acid, wait for absorption, then apply sunscreen. Consider using acids in the evening if pilling occurs.
Layering multiple silicone-heavy products over TiO2 sunscreen can cause pilling. Titanium dioxide sunscreens often contain dimethicone. To reduce pilling: allow each layer to fully dry before applying the next, use lighter formulations, or choose a tinted TiO2 sunscreen that replaces your foundation step.
