Triclosan / Triclocarban
Antibacterial agents in soaps and personal care
Also seen as: triclosan, triclocarban, TCS, TCC
At a glance
Triclosan and triclocarban are antibacterial chemicals once widely added to soaps, body washes, and personal care products. The FDA banned them from over-the-counter consumer antibacterial soaps in 2016 after concluding the manufacturers had not shown the chemicals worked better than plain soap and water — and that there were unanswered questions about hormone effects and antibacterial resistance. They still appear in some toothpastes and a handful of medical products.
Quick facts
- What it isSynthetic antibacterial chemicals
- Main jobKill or inhibit bacteria in soaps and personal care
- How exposure happensSkin contact (soaps), ingestion (toothpaste residue), oral mucosa
- Most relevant forHouseholds still using 'antibacterial' labelled products, people using triclosan-containing toothpaste
- Easy to spot?Yes — usually listed by name; 'antibacterial' label is a flag
- US snapshotFDA banned triclosan and triclocarban from OTC consumer antibacterial wash products in 2016. Toothpaste and some other uses still allowed.
- EU snapshotTriclosan restricted in cosmetics to specific concentrations and product types.
- Global contextMultiple regulators have moved against widespread antibacterial use in everyday consumer products.
Where it commonly shows up
- Personal CareSome toothpaste (e.g., Colgate Total historically), Older 'antibacterial' soaps and body washes
- Cosmetics & MakeupLess common
- Oral CareToothpaste (some), Mouthwash (some)
- Baby & KidsRare now
- Kitchen & FoodSome 'antibacterial' kitchen products (most now removed)
- Cleaning & LaundrySome 'antibacterial' cleaners
- Clothing & TextilesSome 'odour-resistant' clothing and gym wear
- Home & LivingSome 'antibacterial' kitchen utensils and cutting boards
- Other Daily ItemsSome toys and electronics with 'antibacterial' marketing
What to do about it
If you still buy soaps or cleaners labelled 'antibacterial', switch to plain. Plain soap and water works just as well and avoids the unnecessary chemical.
Better choices
- Plain (non-antibacterial) soap and body wash
- Toothpaste without triclosan — check the active ingredients list
Common questions
Each answer is tagged with how settled the evidence is: Established, Estimate, or To check.
What are triclosan and triclocarban in simple terms?Established
They're chemicals designed to kill or stop the growth of bacteria. Triclosan was added to soaps, body washes, and toothpaste; triclocarban was used mainly in bar soaps. For decades they were the go-to antibacterial additive in consumer products.
Why is it used in everyday products?Established
Marketing, mostly. 'Antibacterial' sells. Adding triclosan let companies put 'kills 99.9% of germs' on the label. Trouble is, plain soap and water already does that for normal household use — the FDA looked at the evidence and concluded the antibacterial chemicals weren't actually adding benefit.
What names does it go by on product labels?Established
Triclosan (sometimes 'TCS'), triclocarban (sometimes 'TCC'). On marketing copy, watch for 'antibacterial', 'antimicrobial', 'germ-killing', 'odour-fighting'. These don't always mean triclosan — but they're worth a label check.
Where do we commonly find it at home?Established
Mostly historical now. The biggest remaining everyday exposure is in some toothpastes (notably some versions of Colgate Total) and in older household products people may still have under the sink. Newer products have largely moved away.
How does it enter the body?Established
Skin absorption (from soaps and washes), oral mucosa (from toothpaste — it can be detected in blood and urine after toothpaste use), and ingestion of residues.
How does it affect women, especially during pregnancy?Estimate
Triclosan has shown weak endocrine-disrupting activity in animal studies, with possible effects on thyroid hormone and oestrogen signalling. Human evidence is mixed but real enough that reducing exposure during pregnancy is reasonable. Triclosan crosses the placenta.
How does it affect men's health and fertility?Estimate
Some research links higher triclosan exposure to altered reproductive hormones in men. Effects look small at typical exposure. Lower priority than other chemicals on this list, but easy to reduce.
How does it affect babies, children, and teenagers?Estimate
Concern is mostly about thyroid hormone disruption during sensitive developmental windows. Most baby products no longer use triclosan, but check toothpastes — kids' toothpastes are usually fine, but check the adult one shared with the family.
Does it affect older adults differently?To Check
Less studied. Some interest in thyroid effects and metabolic markers, but not a primary concern group.
What does the strongest evidence say?Established
The strongest case is what the FDA actually said in 2016: there's no evidence that triclosan-containing consumer antibacterial soaps work better than plain soap and water, and there are reasonable concerns about hormone effects and contribution to antibacterial resistance. That regulatory verdict carries weight.
How serious is the risk from normal daily use?Estimate
Low for most people because most products have already removed it. Higher if you're still using older 'antibacterial' soaps or a triclosan-containing toothpaste twice daily.
What are safer alternatives?Established
Plain soap and water for hands, body, and cleaning. For toothpaste, any fluoride toothpaste without triclosan is fine. (Note: fluoride toothpaste is recommended — that's a separate, well-established public-health benefit not to confuse with triclosan.)
How easy or hard is it to avoid?Estimate
Very easy now. Most products have removed it. The main step is a quick check of your toothpaste ingredients and ignoring 'antibacterial' marketing.
What's one simple first step right now?To Check
Check your toothpaste ingredients. If you see 'triclosan' in the active ingredients, switch to a different fluoride toothpaste at the next tube.
What this means for youEstimate
This is mostly a 'done deal' in regulatory terms — but check the corners. Older products in the bathroom cabinet, niche toothpastes, and 'antibacterial' marketing claims still exist. Plain soap is fine. Don't pay extra for antibacterial.
Where can I find reliable information?To Check
FDA on triclosan, EPA on triclosan as a pesticide-registered substance, and ECHA on triclosan in cosmetics. See References below.
