Ingredient review
Titanium Hydroxide
INCI: Titanium Hydroxide
Titanium hydroxide is a gentle mineral opacifier that helps give makeup a smooth, opaque finish, but it's less common than titanium dioxide and offers no UV protection on its own.
In plain English
Titanium hydroxide is a mineral powder that helps make makeup look more solid and less transparent. It's similar to titanium dioxide but has a slightly different chemical structure. In skincare and makeup, it's used to add whiteness or opacity to products like foundations and powders. It's generally considered very safe and unlikely to clog pores or irritate skin.

Quick decision guide
Useful, but context matters
Titanium Hydroxide is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Titanium Hydroxide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Titanium hydroxide is an inorganic compound derived from titanium. It appears as a white powder and is used in cosmetics to provide opacity and whiteness. It is chemically related to titanium dioxide but contains hydroxyl groups instead of oxygen atoms.
How it works
When added to a cosmetic formula, titanium hydroxide particles scatter and reflect light, making the product appear more opaque and covering the skin more effectively. It does not absorb into the skin but sits on the surface, creating a physical barrier that helps even out skin tone.
Pros
Gentle on skin
Titanium hydroxide has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Provides smooth opacity
It helps foundations and powders achieve a uniform, non-sheer finish without heavy or greasy feel.
Cons and cautions
Can look chalky
If used in high amounts, titanium hydroxide may leave a white, powdery cast on the skin, especially on deeper skin tones.
No UV protection
Unlike titanium dioxide, this ingredient does not provide meaningful sun protection, so it shouldn't be relied on for SPF.
Best for
- People with oily or combination skin
- Those looking for a matte, opaque finish in makeup
Use caution if
- Individuals with very dry or flaky skin (may emphasize texture)
- Those seeking broad-spectrum sun protection (use titanium dioxide instead)
Usage tips
Safety summary
Titanium hydroxide is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential. However, inhalation of loose powder forms should be avoided, as with any fine particulate.
Research notes
Research on titanium hydroxide specifically is limited, but it is closely related to titanium dioxide, which has been extensively studied and deemed safe by the Cosmetic Ingredient Review (CIR) panel. No significant safety concerns have been raised for cosmetic use.
Common label clues
- Typical concentration
- Typically 1–10% in color cosmetics; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. Not classified as a UV filter, so it is not regulated as a sunscreen active ingredient.
- Common uses
- Foundations, Concealers, Powders, Sunscreens
- Environmental note
- Titanium hydroxide is mined from natural ores. Its environmental impact is similar to other mineral pigments, with low toxicity to aquatic life when used in typical cosmetic concentrations.
Good to know
- Titanium hydroxide is sometimes listed as 'Titanium Hydrate' on labels.
- It is not a substitute for titanium dioxide in sunscreen products.
