Is Silica safe when breathed in?
Cosmetics2 uses researched2 sourced claims
Where it turns up: filler, mattifier, oil absorption, common. Detox My Life researched silica under 2 different uses, because the same substance means something different in each. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.
Level by use and lens
Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.
Safer swaps: the app's swap catalog has no entry tied to this ingredient yet. When you scan a product that contains it, the app suggests cleaner alternative types for that product; the swap categories list what the catalog covers today.

Under the default Cautious lens silica when breathed in rates Swap: the app would put this near the top of your swap plan. Mainstream (consensus only) rates it Swap; Based (adds the fringe) rates it Swap. Researched 2026-09-03.
Sourced concerns (1)
ConsensusSuspected carcinogenconfidence 100%
Inhalation of respirable crystalline silica dust is carcinogenic to humans and causes silicosis, an incurable lung disease, as well as chronic obstructive pulmonary disease (COPD), and kidney disease.
- Why here
- This claim applies to the inhalation of fine crystalline silica particles that can reach deep into the lungs, leading to inflammation, scarring, and systemic health issues.
- What would have to be true
- Long-term occupational exposure to airborne respirable crystalline silica dust, typically above regulatory limits such as the OSHA Permissible Exposure Limit (PEL) of 50 µg/m³ averaged over an 8-hour workday. Disease can develop after years of exposure, or in acute cases, after months of very high exposure.
- The other side
- Not applicable, as this is a widely recognized health hazard by major regulatory and health organizations.

On skin, left on Low
Under the default Cautious lens silica on skin (left on) rates Low: a little concern, nothing the app would ask you to swap. Mainstream (consensus only) rates it Clean; Based (adds the fringe) rates it Low. Researched 2026-09-03.

EmergingIrritant · allergenconfidence 80%
Studies suggest that nano-silica (particles less than 100 nm) in dermal leave-on products may penetrate the skin, particularly through compromised skin, and has been linked to immune-modulating effects, such as the size-dependent aggravation of atopic dermatitis-like skin lesions in animal models, raising questions about potential systemic exposure and toxicity.
- Why here
- Nano-silica in leave-on products remains on the skin for extended periods, increasing the opportunity for absorption, especially if the skin barrier is compromised.
- What would have to be true
- Dermal application of leave-on cosmetic products containing silica nanoparticles (e.g., <75 nm) on intact or damaged skin.
- The other side
- The Scientific Committee on Consumer Safety (SCCS) has stated that there is no proof that nano-silica penetrates the skin or is toxic, but also indicated insufficient data to definitively rule out these possibilities, calling for more evidence on dermal penetration, particularly through damaged skin, and to exclude potential genotoxic, carcinogenic, and reproductive effects if internal exposure were to occur. Additionally, a 90-day dermal toxicity study in rats with 20 nm colloidal silica nanoparticles found no internal organ damage up to a dose of 2,000 mg/kg.

Not researched here
The engine has no dossier for silica when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
