Titanium Dioxide in EU Cosmetics After the CMR Ruling

Titanium dioxide is one of those ingredients where the headline "it's been classified as a concern" gets repeated without the detail that actually matters for most formulators, which is that the concern is specifically about inhalation. If you're making a cream, a lotion, or a liquid foundation, the situation looks very different than if you're making a loose setting powder or an aerosol spray.

The distinction is about form, not the ingredient itself

Titanium dioxide's classification as a carcinogenic, mutagenic, or reprotoxic (CMR) substance under EU rules is tied to powder form and the inhalation route of exposure, meaning the concern is about breathing in fine particulate titanium dioxide, not about it sitting on your skin in a lotion. That's a meaningful distinction because it changes which product formats actually carry the relevant risk profile.

• Loose powders (setting powders, mineral foundation powders, pressed powders that can produce airborne dust when applied): squarely in the category the inhalation concern targets
• Sprays and aerosols that can aerosolize the ingredient: also squarely relevant
• Creams, lotions, liquid foundations, lipsticks: titanium dioxide isn't airborne in these formats in normal use, so the inhalation-based concern doesn't apply the same way

What this means practically if you formulate powders

If your product line includes a loose powder, whether that's a setting powder, a mineral foundation, or a powder blush, this is worth taking seriously rather than assuming it's a synthetic-fragrance-style issue that only affects mass manufacturers. The EU treats this ingredient's use in powder form as a genuine regulatory question under Regulation (EC) No 1223/2009, and it's exactly the kind of ingredient-specific detail your Cosmetic Product Safety Report and Product Information File need to address if titanium dioxide in powder form is part of your formula.

Since the specific labeling and formulation requirements attached to this classification can be updated and are genuinely a live regulatory area, this is a case where checking the current guidance directly, rather than relying on something you read a year ago, is worth the extra ten minutes.

What this doesn't mean for liquid and cream formats

If your titanium dioxide use is entirely in non-powder, non-aerosolized formats, like a tinted moisturizer or a cream foundation, you're working in a context where the inhalation route simply isn't in play the same way. That doesn't mean titanium dioxide is exempt from every other consideration (it's still an ingredient that needs proper documentation in your safety file like anything else), but the specific CMR inhalation concern is much less directly relevant to how your product is actually used.

Product format	Inhalation exposure risk	Relevance of CMR classification
Loose setting powder	Real, dust generated on application	High
Pressed powder	Some, less than loose powder	Worth reviewing
Aerosol spray	Real, by design	High
Cream/lotion/liquid foundation	Minimal in normal use	Low
Lipstick	Minimal	Low

The EU filing context around this

Remember the broader EU framework this sits inside: you notify through the CPNP portal, you need a Responsible Person established in the EU, and that Responsible Person maintains a Product Information File including a Cosmetic Product Safety Report signed by a qualified safety assessor. Titanium dioxide's classification and form are exactly the kind of ingredient-specific fact your safety assessor needs to weigh when they sign off on that report, particularly if your product is a powder.

Practical steps if titanium dioxide is in your formula

1. Identify the exact form your product takes, powder, spray, or non-aerosolized liquid/cream.
2. If it's a powder or spray format, flag this specifically for your Responsible Person and safety assessor as part of building the CPSR.
3. Check current EU guidance directly rather than relying on general summaries, since classification details and any associated labeling requirements can be updated.
4. Don't assume a non-powder format is automatically a non-issue either, just that the specific inhalation-based concern is less directly applicable.

Cosmetic Comply's EU support is on the way alongside the Canada notification system already live today, and ingredient-specific flags like this one, where the same INCI name carries different weight depending on product form, are exactly the kind of nuance the screening is built to surface rather than treat every use of an ingredient identically.
